    Executive summary

    Purpose o the guideline1

    Severe acute malnutrition affects nearly 20 million preschool-age children, mostly rom the World

    Health Organization (WHO) Arican Region and South-East Asia Region. Malnutrition is a signiicantactor in approximately one third o the nearly 8 million deaths in children who are under 5 years

    o age worldwide (1). WHO established guidelines or the treatment o severe acute malnutrition

    in 1999 and Member States have requested WHO to update their 1999 document Management

    of severe malnutrition: a manual for physicians and other senior health workers (2). This guideline

    presents the updated evidence and practice or key interventions and will also serve to inorm

    revisions o the manual. This guideline does not relect all WHO recommendations related to the

    management o children with severe acute malnutrition but only those related to areas that were

    prioritized by the guideline development group: the WHO Nutrition Guidance Advisory Group

    Subgroup on Nutrition in the Lie Course and Undernutrition 20102012. This group reviewed the

    previously published guidelines and indicated the areas o care and speci ic recommendations that

    should be revised irst in the process o updating all WHO recommendations. Relevant standingrecommendations are included adjacent to updated recommendations, to contextualize updated

    recommendations. Other WHO recommendations will be addressed in uture guideline updates.

    Guideline development methodology

    WHO has developed the present evidence-inormed recommendations using the procedures

    outlined in the WHO handbook for guideline development (3). The steps in this process included:

    (i) identiication o priority questions and outcomes; (ii) retrieval o the evidence; (iii) assessment o

    the quality o evidence and synthesis o the indings; (iv) ormulation o recommendations, including

    uture research priorities; and (v) planning or dissemination, implementation, impact evaluation

    and updating o the guideline. The Grading of Recommendations Assessment, Development and

    Evaluation (GRADE) methodology was ollowed to prepare evidence proiles related to preselected

    topics, based on up-to-date systematic reviews. The WHO Nutrition Guidance Advisory Group

    Subgroup on Nutrition in the Lie Course and Undernutrition 20102012, comprised content experts,

    methodologists, representatives o potential stakeholders and consumers. These experts, together

    with external resource people, participated in three WHO technical consultations, held in Geneva,

    1 This publication is a WHO guideline. A WHO guideline is any document, whatever its title, containing WHO recommen-dations about health interventions, whether they be clinical, public health or policy interventions. A recommendationprovides inormation about what policy-makers, health-care providers or patients should do. It implies a choicebetween different interventions that have an impact on health and that have ramiications or the use o resources. A ullguideline is one that provides complete coverage o a health topic or disease. It is expected to include recommendationsin relation to all aspects o the topic (e.g. surveillance, diagnosis, public health and clinical interventions) and to be ullybased on systematic reviews o the evidence or each aspect. All publications containing WHO recommendations are

    approved by the WHO Guidelines Review Committee.

    GUIDELINE: UPDATES ON THE MANAGEMENT OF SEVERE ACUTE MALNUTRITION IN INFANTS AND CHILDREN

    Switzerland, on 24 June 2010, 1416 March 2011 and 13 February 2012, to scope questions or

    the systematic reviews, review and discuss the evidence, draf the recommendations, and vote on

    their strength, taking into consideration: (i) desirable and undesirable effects o this intervention;

    (ii) the quality o the available evidence; and (iii) values and preerences related to the intervention

    in different settings. The cost o options available to health-care workers in different settings was

    not ormally assessed, owing to lack o primary data in the literature or elsewhere. However, cost

    implications were considered as part o general discussion by the guideline development group,

    namely the Nutrition Guidance Advisory Group members and the external resource people.

    Members o the external experts and stakeholders panel were identiied through a public call or

    comments and peer reviewed the guideline. Everyone involved in the development o this guideline

    submitted declarations o interests. All guideline development group members submitted them

    beore each meeting and also made verbal declarations o interest at the beginning o meetings.

    Available evidence

    The evidence, available or the development o recommendations, was in general o very lowquality, as deined in the WHO handbook for guideline development(3). This was due to the limited

    availability o randomized controlled trials, trials comparing existing WHO recommendations with

    new treatment options, or trials documenting comparisons o diagnosis and treatment methods

    identiied by the guideline development group as requiring review. Where direct evidence was not

    available, indirect evidence rom different population groups, or different intervention strategies has

    been noted, i appropriate. The need or uture research directly addressing several o the areas o

    concern was highlighted. Owing to the scarcity o data on the cost o proposed recommendations,

    it is not possible to directly estimate the inancial implications o implementation o these

    recommendations.

    Recommendations

    1. Admission and discharge criteria or children who are 659 months o age with severe

    acute malnutrition

    Criteria or identiying children with severe acute malnutrition or treatment

    1.1 In order to achieve early identiication o children with severe acute malnutrition in

    the community, trained community health workers and community members should

    measure the mid-upper arm circumerence o inants and children who are 659 months

    o age and examine them or bilateral pitting oedema. Inants and children who are 659

    months o age and have a mid-upper arm circumerence

  • 8/10/2019 Who Reccomendation Malnutrition

    10/123

    3

    Criteria or inpatient or outpatient care1

    1.3 Children who are identiied as having severe acute malnutrition should irst be assessed

    with a ull clinical examination to conirm whether they have medical complications and

    whether they have an appetite. Children who have appetite (pass the appetite test) andare clinically well and alert should be treated as outpatients. Children who have medical

    complications, severe oedema (+++), or poor appetite (ail the appetite test), or present

    with one or more Integrated Management o Childhood Illness (IMCI) danger signs2should

    be treated as inpatients (strong recommendation, low quality evidence).

    Criteria or transerring children rom inpatient to outpatient care3

    1.4 Children with severe acute malnutrition who are admitted to hospital can be transerred

    to outpatient care when their medical complications, including oedema, are resolving

    and they have a good appetite, and are clinically well and alert. The decision to transer

    children rom inpatient to outpatient care should be determined by their clinical condition

    and not on the basis o speciic anthropometric outcomes such as a speciic mid-upperarm circumerence or weight-or-height/length (strong recommendation, low quality

    evidence).

    Criteria or discharging children rom treatment

    1.5. a. Children with severe acute malnutrition should only be discharged rom treatment

    when their:

    weight-or-height/length is 2 Z-score and they have had no oedema or at least

    2 weeks, or

    mid-upper-arm circumerence is 125 mm and they have had no oedema or at

    least 2 weeks.

    b. The anthropometric indicator that is used to conirm severe acute malnutrition should

    also be used to assess whether a child has reached nutritional recovery, i.e. i mid-

    upper arm circumerence is used to identiy that a child has severe acute malnutrition,

    then mid-upper arm circumerence should be used to assess and conirm nutritional

    recovery. Similarly, i weight-or-height is used to identiy that a child has severe acute

    malnutrition, then weight-or-height should be used to assess and conirm nutritional

    recovery.

    c. Children admitted with only bilateral pitting oedema should be discharged rom

    treatment based on whichever anthropometric indicator, mid-upper arm circumerence

    or weight-or-height is routinely used in programmes.

    d. Percentage weight gain should not be used as a discharge criterion

    (strong recommendation, low quality evidence).

    Follow-up o inants and children afer discharge rom treatment orsevere acute malnutrition

    1.6. Children with severe acute malnutrition who are discharged rom treatment programmes

    should be periodically monitored to avoid a relapse (strong recommendation, low

    quality evidence).

    EXECUTIVE SUMMARY

    1 Necessar y resources and serv ices need to be in place i children are reerred to outpatient care.2 Danger signs: unable to drink or breasteed; vomits every thing; has had convulsions (more than one or prolonged

    >15 min); lethargic or unconscious; convulsing now.3 Necessar y resources and serv ices need to be in place i children are reerred to outpatient care.

    GUIDELINE: UPDATES ON THE MANAGEMENT OF SEVERE ACUTE MALNUTRITION IN INFANTS AND CHILDREN

    2. Where to manage children with severe acute malnutrition who have oedema

    2.1 Children with severe acute malnutrition who have severe bilateral oedema (+++),1even i

    they present with no medical complications and have appetite, should be admitted or

    inpatient care (strong recommendation, ver y low quality evidence).

    3. Use o antibiotics in the management o children with severe acute malnutrition in

    outpatient care

    3.1 Children with uncomplicated severe acute malnutrition, not requiring to be admitted

    and who are managed as outpatients, should be given a course o oral antibiotic such as

    amoxicillin (conditional recommendation, low quality evidence).

    3.2 Children who are undernourished but who do nothave severe acute malnutrition should

    not routinely receive antibiotics unless they show signs o clinical inection (strong

    recommendation, low quality evidence).

    4. Vitamin A supplementation in the treatment o children with severe acute malnutrition

    4.1 Children with severe acute malnutrition should receive the daily recommended nutrient

    intake o vitamin A throughout the treatment period. Children with severe acute mal-

    nutrition should be provided with about 5000 IU vitamin A daily, either as an integral part

    o therapeutic oods or as part o a multi-micronutrient ormulation (strong recommen-

    dation, low quality evidence).

    4.2 Children with severe acute malnutrition do not require a high dose o vitamin A as a

    supplement i they are receiving F-75, F-1002 or ready-to-use therapeutic ood that

    complies with WHO speciications (and thereore already contains sufficient vitamin A),

    or vitamin A is part o other daily supplements (strong recommendation, low quality

    evidence).

    4.3. Children with severe acute malnutrition should be given a high dose o vitamin A (50 000 IU,100 000 IU or 200 000 IU, depending on age) on admission, only i they are given therapeutic

    oods that are not ortiied as recommended in WHO speciications and vitamin A is not

    part o other daily supplements (strong recommendation, low quality evidence).

    5. Therapeutic eeding approaches in the management o severe acute malnutrition in

    children who are 659 months o age

    5.1 Children with severe acute malnutrition who present with either acute or persistent

    diarrhoea, can be given ready-to-use therapeutic ood in the same way as children

    without diarrhoea, whether they are being managed as inpatients or outpatients (strong

    recommendation, very low quality evidence).

    5.2 In inpatient settings, where ready-to-use therapeutic food is provided as the therapeutic foodin the rehabilitation phase (following F-75 in the stabilization phase)

    Once children are stabilized, have appetite and reduced oedema and are thereore ready

    to move into the rehabilitation phase, they should transition rom F-75 to ready-to-use

    therapeutic ood over 23 days, as tolerated. The recommended energy intake during this

    1 + Mild: both eet; ++ moderate: both eet, plus lower legs, hands, or lower arms; +++ severe: generalized oedemaincluding both eet, legs, hands, arms and ace. Source: Module 2. Principles o care. In: WHO training course on themanagement of severe malnutrition. Geneva: World Health Organization; 2002 (updated 2009).

    2 F-75 and F-100 are ormula diets used or the management o children with severe acute malnutrition in inpatient care.F-75 (75 kcal or 315 kJ/100 mL) is used during the initial phase o treatment, while F-100 (100 kcal or 420kJ/100 mL) is

    used during the rehabilitation phase.

  • 8/10/2019 Who Reccomendation Malnutrition

    12/123

    5

    period is 100135 kcal/kg/day. The optimal approach or achieving this is not known and

    may depend on the number and skills o staff available to supervise eeding and monitor

    the children during rehabilitation (strong recommendation, very low quality evidence).

    Two options or transitioning children rom F-75 to ready-to use therapeutic ood are

    suggested:

    a. start eeding by giving ready-to-use therapeutic ood as prescribed or the transition

    phase. Let the child drink water reely. I the child does not take the prescribed amount

    o ready-to-use therapeutic ood, then top up the eed with F-75. Increase the amount

    o ready-to-use therapeutic ood over 23 days until the child takes the ull requirement

    o ready-to-use therapeutic ood, or

    b. give the child the prescribed amount o ready-to-use therapeutic ood or the

    transition phase. Let the child drink water reely. I the child does not take at least hal

    the prescribed amount o ready-to-use therapeutic ood in the irst 12 h, then stop

    giving the ready-to-use therapeutic ood and give F-75 again. Retry the same approach

    afer another 12 days until the child takes the appropriate amount o ready-to-usetherapeutic ood to meet energy needs.

    5.3 In inpatient settings where F-100 is provided as the therapeutic food in the rehabilitation

    phase

    Children who have been admitted with complicated severe acute malnutrition and are

    achieving rapid weight gain on F-100 should be changed to ready-to-use therapeutic ood

    and observed to ensure that they accept the diet beore being transerred to an outpatient

    programme (strong recommendation, ver y low quality evidence).

    6. Fluid management o children with severe acute malnutrition

    6.1 Children with severe acute malnutrition who present with some dehydration or severe

    dehydration but who are not shockedshould be rehydrated slowly, either orally or by naso-gastric tube, using oral rehydration solution or malnourished children (510 mL/kg/h up

    to a maximum o 12 h) (strong recommendation, low quality evidence).

    6.2 Full-strength, standard WHO low-osmolarity oral rehydration solution (75 mmol/L o

    sodium) should not be used or oral or nasogastric rehydration in children with severe

    acute malnutrition who present with some dehydration or severe dehydration. Give either

    ReSoMal or hal-strength standard WHO low-osmolarity oral rehydration solution with

    added potassium and glucose, unless the child has cholera or prouse watery diarrhoea

    (strong recommendation, low quality evidence).

    Dissolve one sachet of standard WHO low-osmolarity oral rehydration solution in 2 L water

    (instead of 1 L). Add 1 level scoop of commercially available combined minerals and vitaminsmix1or 40 ml of mineral mix solution (5), and add and dissolve 50 g of sugar. In some countries,

    sachets are available that are designed to make 500 mL of standard WHO low-osmolarity

    oral rehydration solution. In this situation, dilution can be revised to add 1 L.

    6.3 ReSoMal2 (or locally prepared ReSoMal using standard WHO low-osmolarity oral

    rehydration solution) should not be given i children are suspected o having cholera

    EXECUTIVE SUMMARY

    1 A speciic electrolyte micronutr ient product ormulated according to WHO speciications or use in the management ochildren with severe acute malnutrition.

    2 ReSoMal (short or rehydration solution or severely malnourished children) is the generic name or a powder or thepreparation o an oral rehydration solution exclusively or oral or nasogastric rehydration o people suffering romsevere acute malnutrition. It must be used exclusively under medical supervision in inpatient care, and must not be

    given or ree use to the mother or caregiver.

    GUIDELINE: UPDATES ON THE MANAGEMENT OF SEVERE ACUTE MALNUTRITION IN INFANTS AND CHILDREN

    or have prouse watery diarrhoea.1 Such children should be given standard WHO low-

    osmolarity oral rehydration solution that is normally made, i.e. not urther diluted (strong

    recommendation, low quality evidence).

    6.4 Children with severe acute malnutrition and signs o shock or severe dehydration and whocannot be rehydrated orally or by nasogastric tube should be treated with intravenous

    luids, either:

    a. hal-strength Darrows solution with 5% dextrose, or

    b. Ringers lactate solution with 5% dextrose.

    I neither is available, 0.45% saline + 5% dextrose should be used (conditional recommen-

    dation, very low quality evidence).

    7. Management o HIV-inected children with severe acute malnutrition

    7.1 Children with severe acute malnutrition who are HIV inected and who qualiy or lielong

    antiretroviral therapy should be started on antiretroviral drug treatment as soon aspossible afer stabilization o metabolic complications and sepsis. This would be indicated

    by return o appetite and resolution o severe oedema. HIV-inected children with severe

    acute malnutrition should be given the same antiretroviral drug treatment regimens, in

    the same doses, as children with HIV who do not have severe acute malnutrition. HIV-

    inected children with severe acute malnutrition who are started on antiretroviral drug

    treatment should be monitored closely (inpatient and outpatient) in the irst 68 weeks

    ollowing initiation o antiretroviral therapy, to identiy early metabolic complications and

    opportunistic inections (strong recommendation, ver y low quality evidence).

    7.2 Children with severe acute malnutrition who are HIV inected should be managed with the

    same therapeutic eeding approaches as children with severe acute malnutrition who are

    not HIV inected (strong recommendation, ver y low quality evidence).7.3 HIV-inected children with severe acute malnutrition should receive a high dose o vitamin

    A on admission (50 000 IU to 200 000 IU depending on age) and zinc or management o

    diarrhoea, as indicated or other children with severe acute malnutrition, unless they are

    already receiving F-75, F-100 or ready-to-use therapeutic ood, which contain adequate

    vitamin A and zinc i they are ortiied ollowing the WHO speciications (strong recom-

    mendation, very low quality evidence).

    7.4 HIV-inected children with severe acute malnutrition in whom persistent diarrhoea does

    not resolve with standard management should be investigated to exclude carbohydrate

    intolerance and inective causes, which may require different management, such as

    modiication o luid and eed intake, or antibiotics (strong recommendation, very low

    quality evidence).

    8. Identiying and managing inants who are less than 6 months o age with severe acute

    malnutrition

    8.1 Inants who are less than 6 months o age with severe acute malnutrition and any o the

    ollowing complicating actors should be admitted or inpatient care:

    a. any serious clinical condition or medical complication as outlined or inants who are

    6 months o age or older with severe acute malnutrition;

    b. recent weight loss or ailure to gain weight;

    1

    Three or more loose or watery stools in a day, or more than 14 days.

  • 8/10/2019 Who Reccomendation Malnutrition

    14/123

    7

    c. ineffective eeding (attachment, positioning and suckling) directly observed or

    1520 min, ideally in a supervised separated area;

    d. any pitting oedema;

    e. any medical or social issue needing more detailed assessment or intensive support

    (e.g. disability, depression o the caregiver, or other adverse social circumstances)

    (strong recommendation, ver y low quality evidence).

    8.2 Inants who are less than 6 months o age with severe acute malnutrition should receive the

    same general medical care1as inants with severe acute malnutrition who are 6 months

    o age or older:

    a. inants with severe acute malnutrition who are admitted or inpatient care should be

    given parenteral antibiotics to treat possible sepsis and appropriate treatment or

    other medical complications such as tuberculosis, HIV, surgical conditions or disability;

    b. inants with severe acute malnutrition who are not admitted should receive a courseo broad-spectrum oral antibiotic, such as amoxicillin, in an appropriately weight-

    adjusted dose

    (strong recommendation, ver y low quality evidence).

    8.3 Feeding approaches or inants who are less than 6 months o age with severe acute

    malnutrition should prioritize establishing, or re-establishing, effective exclusive breast-

    eeding by the mother or other caregiver (strong recommendation, very low quality

    evidence).

    8.4 Inants who are less than 6 months o age with severe acute malnutrition and who are

    admitted:

    a. should be breasted where possible and the mothers or emale caregivers should besupported to breasteed the inants. I an inant is not breasted, support should be

    given to the mother or emale caregiver to re-lactate. I this is not possible, wet nursing2

    should be encouraged;

    b. should also be provided a supplementary eed:

    supplementary suckling approaches should, where easible, be prioritized;

    or inants with severe acute malnutrition but no oedema, expressed breast milk

    should be given, and, where this is not possible, commercial (generic) inant ormula

    Research priorities

    Guideline group members and stakeholders identiied several research priorities to improve the

    body o evidence at the basic, clinical, epidemiological and operational levels on the management

    o severe acute malnutrition in inants and children. Major research gaps were identiied in each o

    the sections covered. SeeAnnex 7or a compiled list.

    Scope and purpose

    This guideline provides global, evidence-inormed recommendations on a number o speciic issues

    related to the management o severe acute malnutrition in inants and children. In conjunction

    with other World Health Organization (WHO) recommendations,1 it provides evidence-inormed

    guidance on the care o inants and children with severe malnutrition, including in the context oHIV.

    The guideline will help Member States and their partners in their efforts to make inormed decisions

    on the appropriate nutrition actions or severely malnourished children, and contribute to achieving

    the Millennium Development Goals (MDGs), particularly reduction in child mortality (MDG 4). It will

    also support Member States in their efforts to achieve global targets on the maternal, inant and

    young child nutrition comprehensive implementation plan, especially global target 1, which entails

    achieving 40% reduction by 2025 o the global number o children under 5 years who are stunted

    and global target 6, which aims to reduce and maintain childhood wasting to less than 5%. (6).

    The guideline is intended or a wide audience, including policy-makers, their expert advisers, and

    technical and programme staff in organizations involved in the design, implementation and scaling-

    up o nutrition actions or public health. The guideline will orm the basis or a revised manual onthe management o severe malnutrition or physicians and other senior health workers), a training

    course on the management o severe malnutrition and other training materials.

    This document presents the key recommendation and a summary o the supporting evidence.

    1 This guideline does not relec t all WHO recommendations related to the management o children with severe acutemalnutrition but only those related to areas o care that were prioritized by the guideline development group advisingWHO or this guideline. Relevant standing recommendations are included adjacent to updated recommendations, to

    contextualize updated recommendations.

    Background

    It is estimated that 19 million preschool-age children, mostly rom the WHO Arican Region and

    South-East Asia Region, are suffering rom severe wasting (7). Childhood undernutrition is a major

    global health problem, contributing to childhood morbidity, mortality, impaired intellectual

    development, suboptimal adult work capacity, and increased risk o diseases in adulthood (7). Othe 7.6 million deaths annually among children who are under 5 years o age (1), approximately

    35% are due to nutrition-related actors and 4.4% o deaths have been shown to be speciically

    attributable to severe wasting (7). Severe acute malnutrition remains a major cause o child mortality

    worldwide. While pneumonia and diarrhoea are ofen the inal steps in the pathway, severe wasting

    is estimated to account or around 400 000 child deaths each year (7). For this reason, the improved

    management o severe acute malnutrition is an integral part o the World Health Resolution on Infant

    and Young Child Nutrition(WHA 63.23), to improve child survival and to reduce the global burden o

    disease.

    In 2006, WHO released new growth standards or children aged 05 years (8). These represent the

    standards on which all WHO deinitions and estimates o malnutrition, including moderate and

    severe acute malnutrition, and obesity are now based. In children who are 659 months o age,severe acute malnutrition is deined as weight-or-height less than 3 Z-score1 o the median o

    the WHO growth standards, or clinical signs o bilateral oedema o nutritional origin, despite other

    measures being above speciied cut-off values (9). Since publication o the WHO Management of

    severe malnutrition: a manual for physicians and other senior health workers (2), a joint statement by

    the World Health Organization, World Food Programme, United Nations Standing Committee on

    Nutrition and United Nations Childrens Fund (UNICEF) in 2007 (10)acknowledged the easibility o

    community health workers or volunteers identiying children affected by severe acute malnutrition,

    using simple coloured plastic strips that are designed to measure mid-upper arm circumerence.

    In children who are 659 months o age, a mid-upper arm circumerence less than 115 mm also

    indicates severe acute malnutrition, allowing early identiication o affected children within the

    community beore the onset o complications.Major challenges remain to implementation o effective use o growth monitoring in primary

    health-care settings, to identiy the most at-risk inants and children who need medical and

    nutritional interventions to prevent serious morbidity and mortality. The importance o this is

    highlighted by the strong epidemiological evidence that low weight-or-height, weight-or-length

    or mid-upper arm circumerence are highly associated with a 520-old increased risk o mortality

    (11). At the same time, it is necessary to examine the implications o very low anthropometry in

    different epidemiological settings, especially South East Asia, and to establish the equivalent

    anthropometric thresholds or older children and adolescents.

    1 A Z-score (or standard deviation score) is the deviation o the value or an individual rom the median value o thereerence population, divided by the standard deviation or the reerence population. We reer herein to the median o

    the WHO growth standards.

    Malnutrition in children typically develops during the period rom 6 to 18 months o age, when growth

    velocity and brain development are especially high. Young children are particularly susceptible

    to malnutrition i complementary oods are o low nutrient density and have low bioavailability

    o micronutrients. In addition, childrens nutritional status will be urther compromised i

    complementary oods are introduced too early or too late, or are contaminated.

    The nutritional status o children can also be affected by chronic inections such as HIV. It is

    estimated that over 2 million children worldwide are living with HIV, 90% o them in sub-Saharan

    Arica (12). In a report describing children admitted to hospital in southern Arica, the prevalence o

    HIV in children with severe acute malnutrition was 29% and these children were more likely to die

    than malnourished children who were not inected with HIV (13). Higher HIV prevalence, i.e. up to

    50%, has been reported among children with severe acute malnutrition (14).

    Children with severe acute malnutrition have prooundly disturbed physiology and metabolism,

    such that i intensive reeeding is initiated beore metabolic and electrolyte imbalances have

    been corrected, mortality rates are high. For this reason, WHO developed clinical guidance (2) on

    the management o the child with severe acute malnutrition. This guidance was updated in partthrough subsequent WHO publications on the outpatient management(10)and inpatient treatment

    o children with severe acute malnutrition (15, 16). Outpatient treatment o uncomplicated severe

    acute malnutrition is increasingly provided, using ready-to-use therapeutic oods (10). These are

    high-energy, ortiied, ready-to-eat oods that have a nutrient content/100 kcal similar to that o

    F-100, the therapeutic diet used to treat children with severe acute malnutrition in hospital settings.

    Unlike F-100, however, ready-to-use therapeutic oods are not water based, meaning that bacteria

    are less likely to grow in them. These oods can thereore be used saely at home or in hospital

    without rerigeration and even in areas where hygiene conditions are not optimal. Ready-to-use

    therapeutic ood can be consumed easily by children rom the age o 6 months and have been

    shown to be effective in treating children with severe acute malnutrition in communities or in

    hospital afer the stabilization phase. The technology to produce ready-to-use therapeutic ood

    is simple and can be transerred to any country with minimal industrial inrastructure, while still

    complying with the Recommended international code of hygienic practice for foods for infants and

    childreno the Codex Alimentarius Standard CAC/RCP 21-1979 (17).

    These signiicant advances have not been matched by research and development in other key areas

    o clinical management o children with severe acute malnutrition. Furthermore, the HIV epidemic

    has produced a number o new research questions related to the basic science and clinical

    management o undernutrition in children inected with HIV. While some o the basic principles and

    lessons or managing children without HIV can be extended to HIV-inected children, there is little

    empirical evidence to guide management o this speciic population.

    Increasingly, severe acute malnutrition is being documented among inants who are less than

    6 months o age. However, there are ew data describing to what extent the pathophysiology inthis population is the same as that in older children and how to approach therapeutic eeding,

    including the support and/or supplementation o breasteeding. The lack o epidemiological and

    intervention data in young inants is common also or children who are older than 5 years. WHO

    has commissioned systematic reviews and convened a guideline development group to ormulate

    guidelines or this important age group.

    Lastly, the epidemiological and clinical implications o the WHO child growth standards and the

    populations that will be deined as having severe acute malnutrition need to be examined. While

    increased mortality has been reported among children with severe acute malnutrition in several

    Arican countries and Bangladesh, the burden o disease based on the revised growth standards

    has not been estimated, especially in India and other settings in South Asia.

    GUIDELINE: UPDATES ON THE MANAGEMENT OF SEVERE ACUTE MALNUTRITION IN INFANTS AND CHILDREN

    Given developments in treatment options or severely malnourished children and the increasing

    prevalence o HIV as an adjunct to undernutrition, certain aspects o the existing guidelines on the

    management and treatment o severe acute malnutrition needed updating and revision. Following

    the review (18)o the existing recommendations (2, 9, 10), WHO identiied the eight ollowing major

    areas where revision o guidelines was needed:

    1. Admission and discharge criteria or children who are 659 months o age with severe acute

    malnutrition

    Admission cut-off values or the respective screening indicators

    Discharge cut-off values or the different admission indicators

    Admission criteria or inpatient care and outpatient care

    Transition rom inpatient care to outpatient care afer stabilization

    2. Where to manage children with severe acute malnutrition who have oedema

    Which children with severe acute malnutrition who also have oedema should be managed inhospital compared to at home?

    3. Use o antibiotics in the management o children with severe acute malnutrition in outpatient

    care

    Do children with uncomplicated severe acute malnutrition need to be treated with antibiotics

    and, i so, then which antibiotic should be used?

    4. Vitamin A supplementation in the treatment o children with severe acute malnutrition

    What is the effectiveness and saety o giving high-dose vitamin A supplementation to

    children with severe acute malnutrition when they are receiving a WHO-recommended

    therapeutic diet containing vitamin A?

    How does the timing o high-dose vitamin A supplementation (i.e. at the beginning, afer

    stabilization or afer rehabilitation) affect the effectiveness and saety o the management o

    children with severe acute malnutrition?

    5. Therapeutic eeding approaches in the management o severe acute malnutrition in children

    who are 659 months o age

    Does ready-to-use therapeutic ood given to children with severe acute malnutrition as

    outpatients increase the incidence o acute diarrhoea or worsen acute diarrhoea i already

    present?

    Do children with severe acute malnutrition and acute diarrhoea who are managed as

    outpatients require modiication o therapeutic eeding approaches? Does ready-to-use therapeutic ood given to children with severe acute malnutrition in

    the rehabilitation phase, as either inpatients or outpatients, increase the prevalence o

    diarrhoea or worsen diarrhoea i already present, in comparison to F-100?

    Can ready-to-use therapeutic ood be given saely to children with severe acute malnutrition

    who have persistent diarrhoea?

    What is the most appropriate transition eeding approach or changing rom F-75 to F-100,

    or rom F-75 to ready-to-use therapeutic ood, or children with severe acute malnutrition

    who are managed in hospital?

    What is the optimal timing or initiating and dosing o antiretroviral drug treatment?

    What are the optimal eeding regimens or HIV-inected children with severe acute malnutri-

    tion and do these differ rom those or uninected children with severe acute malnutrition?

    What is the value (effectiveness and saety) o vitamin A supplementation?

    What are the most effective therapeutic strategies or managing diarrhoea?

    What are the criteria or deining severe acute malnutrition in inants who are less than 6

    months o age?

    What are the criteria or hospital admission o inants who are less than 6 months o age with

    severe acute malnutrition?

    What are the essential interventions, especially eeding approaches, or inants who are less

    than 6 months o age with severe acute malnutrition?

    What are the criteria or transerring inants who are less than 6 months o age and have

    been treated in hospital or severe acute malnutrition to outpatient care, or discharging

    them rom treatment?

    Recommendations

    1. Admission and discharge criteria or children who are659 months o age with severe acute malnutrition

    Preamble

    Severe malnutrition in children who are 659 months o age was deined in previous publications(2)

    as weight-or-height (or length) less than 3 Z-score, or less than 70% o the median National Center

    or Health Statistics (NHCS)/WHO reerence values, or the presence o oedematous malnutrition.

    The manual recommended admitting children with severe acute malnutrition to hospital or initial

    treatment and rehabilitation, and to continue treatment as outpatients (transer to a nutritional

    rehabilitation centre) when children have completed the initial phase o the treatment, have no

    complications, and are eating satisactorily and gaining weight (2). Since ready-to-use therapeutic

    ood became available in the 1990s, reports have demonstrated that most children with severe

    acute malnutrition can be treated saely without admission to hospital (19). Consequently, in 2007

    a joint United Nations statement endorsed outpatient care o children who are 659 months o

    age with severe acute malnutrition and who present with no medical complications and with

    good appetite (10). The same statement also endorsed the use o mid-upper arm circumerence

    measurements as an independent criterion or screening.

    The transition rom the NCHS growth reerence to the WHO growth standards in 2006 (4)prompted

    the revision o cut-off values or indicators o severe acute malnutrition. A 2009 joint United Nations

    statement endorsed a low mid-upper arm circumerence less than 115 mm as a criterion or

    diagnosing severe acute malnutrition in children, in light o the high predictive value or mortality

    (9). Mid-upper arm circumerence is measured using simple arm bands that are marked in millimetre

    graduations and are sometimes colour coded. These armbands can be used and interpreted by

    health-care workers who receive appropriate training. The statement also noted the programmatic

    advantage o using a single mid-upper arm circumerence cut-off value to identiy children with

    severe acute malnutrition in this age group (9). However, mid-upper arm circumerence and weight-

    or-height indicators do not always correlate when used to identiy children with severe acute

    malnutrition(2022). About 40% o children who are classiied as having severe acute malnutrition

    using one o these indicators are similarly classiied using the other indicator (8). The agreement

    between these criteria varies considerably between settings and geographic location (9, 23).

    Comparison o the sensitivityspeciicity curves (receiver operating characteristic curves) in

    community studies shows that mid-upper arm circumerence is better at identiying children with

    a high risk o death (24).

    The 1999 recommendations included discharging children rom hospital care when they achieved a

    weight-or-height 1 Z-score or 90% o the median NCHS/WHO reerence values (2). The 2009 joint

  • 8/10/2019 Who Reccomendation Malnutrition

    22/123

    15

    United Nations statement proposed using a single discharge criterion o 15% (or 20%, depending on

    the local context) weight gain over oedema-ree weight on enrolment, or children admitted based

    on weight-or-height or mid-upper arm circumerence, as well as absence o oedema or 2 weeks (9).

    Data rom children treated or severe acute malnutrition in outpatient care in Malawi and Ethiopia

    have suggested that 15% weight gain would result in 50% o children with severe acute malnutrition

    meeting or exceeding 80% o the median weight-or-height o the NCHS reerence (25). However,

    while some programmes adopted this approach, there was concern about its validity as an indicator

    o nutritional recovery, and in many settings only the mid-upper arm circumerence cut-off value

    o 125 mm was applied (26). The discharge cut-off value or mid-upper arm circumerence o 125

    mm was based on historical cohort studies rom Bangladesh, Malawi and Uganda that suggested

    that mortality risk at this cut-off value did not exceed 1/10 000 per day (25). The saety o using

    changes in mid-upper arm circumerence as an indicator o progress o recovery during nutritional

    rehabilitation, and a single cut-off value to indicate recovery, has not been validated.

    In light o these experiences, WHO, with support rom the guideline development group aimed to

    provide guidance on the ollowing:

    Admission and discharge criteria or children who are 659 months o age with severe acute

    malnutrition:

    Admission cut-off values or the respective screening indicators

    Discharge cut-off values or the different admission indicators

    Admission criteria or inpatient care and outpatient care

    Transition rom inpatient care to outpatient care afer stabilization

    Summary o the evidence

    A systematic review was conducted to examine admission and discharge criteria or severeacute malnutrition in children who are 659 months o age (27). The search identiied 11 relevant

    epidemiological studies. Three o the 11 studies used cut-off values or admission that did not

    correspond to the WHO deinition o severe acute malnutrition, namely mid-upper arm circumerence

  • 8/10/2019 Who Reccomendation Malnutrition

    (mid-upper arm circumerence initially 114 mm) was 47 25 days, which was longer than or the less

    malnourished children (initial mid-upper arm circumerence between 115 mm and 119 mm) who

    were discharged on average afer 33 16 days. These observations provide indirect evidence that

    15% weight gain is not an appropriate discharge criterion, because it results in the more severely

    malnourished children getting the shortest duration o treatment and being discharged when still

    malnourished. In this study, the mortality risks up until the end o treatment when using 15% weight

    gain versus mid-upper arm circumerence 124 mm as a discharge criterion were comparable and

    were 1.5 %. The second study in Guinea-Bissau used a mid-upper arm circumerence 130 mm as

    a discharge criterion but did not separate outcomes or children who were admitted with severe

    acute malnutrition rom those with moderate acute malnutrition (29).

    No published data were ound that reported the inal outcome status o children with severe acute

    malnutrition ollowing discharge rom treatment programmes, e.g. relapse rates; subsequent

    mortality when discharged was based on a mid-upper arm circumerence measurement compared

    to other indicators such as weight-or-height Z-score, mid-upper arm circumerence-or-age Z-score,

    or mid-upper arm circumerence-or-height Z-score.

    The overall quality o evidence was rated as low or the relationship between anthropometry and

    mortality risk on admission. There was no evidence available inorming the relationship between

    anthropometry and the risk o mortality post discharge. The quality o evidence or other important

    outcomes, including time to recovery, growth and daily weight gain was rated very low or low, owing

    to methodological and reporting issues. A Grading o Recommendations Assessment, Development

    and Evaluation (GRADE) summary o the evidence was not developed, as the published data were

    epidemiological reports rather than comparative studies.

    Only one o the studies reported outcomes in children identiied, monitored or discharged based

    on mid-upper arm circumerence and also by weight-or-height, and this was carried out among

    hospitalized children. Few o the studies addressed the precision and accuracy o anthropometric

    measurements, which may affect reliability. The act that most o the studies were done in Malawi,where the majority o cases are oedematous and the prevalence o HIV inection is high, may affect

    the external validity (30, 3438). No studies were retrieved reporting on a number o important

    outcomes, i.e. costs, adverse effects and population coverage.

    Discussion

    The guideline group noted that the development o ready-to-use therapeutic ood has made

    outpatient management o children with severe acute malnutrition more easible and saer.

    Active community screening makes it possible to identiy and treat these children early as

    outpatients. It also allows children to be appropriately managed while avoiding the risk and

    problems o inpatient care, such as nosocomial inections, patient transport and costs anddisruptions to amilies. Screening in the community has been acilitated by the easibility o

    using mid-upper arm circumerence to identiy severely malnourished children.

    Depending on the age group, and excluding consideration o oedematous malnutrition,

    anthropometric assessments based on weight-or-height using the WHO growth standards

    (8)are likely to identiy a larger population with severe acute malnutrition than NCHS growth

    reerence values. This has a major implication or countries in South and South-East Asia,

    where large numbers o inants and young children would be deined as having severe acute

    malnutrition, using the WHO growth standards.

    The guideline group noted that while weight-or-height and mid-upper arm circumerence are

    good methods to assess wasting, both require training and methodical implementation to

    achieve reliable assessments. Even afer training, signiicant variation has been noted in health-

    care workers measurements and classiication during standardization tests.

    The guideline group agreed that children with severe acute malnutrition identiied using weight-

    or-height do not consistently have a mid-upper arm circumerence

    26/123

    19

    The guideline group noted that the decision to transer children rom inpatient care to outpatient

    care (i.e. discharge rom hospital) afer the initial phase o stabilization should be guided

    primarily by the childrens clinical condition, including appetite and response to treatment, and

    also social circumstances.

    The guideline group noted that percentage weight gain should no longer be used as a criterion

    or discharge rom treatment.

    The guideline group noted that correlations o anthropometric indicators with risk o death and

    response to treatment are urgently needed to inorm clinical recommendations and guidelines

    or managing severe acute malnutrition in inants less than 6 months old and in children 5 years

    and older, especially in the context o HIV.

    The guideline development group noted that the quality o evidence was low or the relationship

    between anthropometry and mortality risk on admission and very low/low or the relationship

    between anthropometr y and time to recovery, growth and weight gain. However, the guideline group

    agreed that the recommendation should be strong. The group recognized that the associations

    between anthropometric outcomes and high mortality risks originated largely rom observational or

    population-based studies rather randomized trials. Other evidence inorming the recommendations

    was also based on programmatic experience and this characteristically downgrades the quality o

    evidence. However, it was elt that examining these issues through randomized trials would be very

    difficult and possibly unethical. The guideline group also considered that there is high biological

    plausibility or the associations between poor anthropometry and mortality. The beneits o

    identiying and treating children with severe acute malnutrition through screening with mid-upper

    arm circumerence were determined to ar outweigh the possible disadvantage o overdiagnosing

    malnutrition and causing children to be urther assessed. The recommendations were considered

    to be easible and sustainable in low-resource settings, even though there were no cost data

    available. As has been reported in a limited number o settings, community screening does increase

    the rate o identiication o children with severe acute malnutrition. This will result in increased

    costs to the health system as treatment, either as inpatients or in the community. However, it is also

    likely that earlier identiication will enable children to be successully treated at home without the

    costs o hospitalization or complications associated with later presentation, or through nosocomial

    inection. Community-based management will also probably reduce transportation costs to the

    amily and time away rom home. The guideline group viewed the other recommendations in asimilar way and that their overall beneits ar outweighed any potential harm. However, there are

    several important research questions that need to be addressed to give greater certainty to these

    recommendations.

    2. Where to manage children with severe acute malnutritionwho have oedema

    Preamble

    The standard recommendation or the management o severe acute malnutrition has been

    inpatient care during the stabilization phase and the irst part o the rehabilitation phase, and then

    transer to a nutrition rehabilitation centre (when they exist) or the rest o the rehabilitation phase

    (42). However, inpatient treatment is resource intensive (43), disrupts the amily and places children

    at risk o nosocomial inections. Reports o children with severe acute malnutrition being effectively

    treated at home (34, 35, 44)have prompted categorization o severe acute malnutrition as being

    with or without medical complications (43, 45). Cases are uncomplicated i there are no signs o

    severe clinical illness and the child has a good appetite. Using this classiication, WHO, UNICEF

    and the World Food Programme recommend treating children with uncomplicated severe acute

    malnutrition as outpatients whenever possible (10). Children with severe acute malnutrition whohave severe bilateral oedema (+++) have an increased risk o mortality compared to children with

    severe acute malnutrition but with lesser degrees o oedema. For this reason, it is unclear whether

    the severity o oedema, in the absence o other complications and with adequate appetite, should

    independently inluence where to treat children with severe acute malnutrition.

    The guideline development group aimed to review the evidence and provide guidance on the

    ollowing question:

    Which children with severe acute malnutrition who also have oedema should be managed in

    hospital compared to at home?

    Summary o the evidence

    A systematic review examined the evidence on the effectiveness o managing children who are more

    than 6 months o age with uncomplicated oedematous malnutrition grade +/++, 1 in ambulatory

    settings (46). No randomized controlled trials comparing the outcomes achieved in inpatient and

    outpatient care or this speciic group were identiied. However, eight reports were ound that

    described outcomes o children with severe acute malnutrition who had bilateral oedema and who

    were treated as outpatients. The data were rom case-series that did not have control groups and

    so comparisons were not thereore possible.

    Among uncomplicated cases o oedematous malnourished children, recovery rates exceeded 88%

    and case-atality rates remained below 4%. Oedema classiication varied among the studies and in

    some studies it was not clear whether children with severe oedema were excluded rom outpatient

    treatment. These outcomes are consistent with those recommended in the Sphere guidelines(47)

    and the Prudhon index or case-atality rates (48). However, complicated cases were associated

    with high case-atality rates during the irst 4 days o inpatient stabilization, especially in the context

    o HIV inection (49). The weight gain o children with oedema who were treated as outpatients was

    reported in only two studies and the time to nutritional recovery was prolonged and did not meet

    the minimum Sphere standards (47). Authors suggested that this was due to sharing o ready-to-use

    therapeutic ood at home or absence o ood supplementation in the home-based treatment group

    (51). Methods to assess weight gain were not, however, uniorm across the studies. No association

    was reported between the severity o oedema and the likelihood o nutritional recovery or not.

    GUIDELINE: UPDATES ON THE MANAGEMENT OF SEVERE ACUTE MALNUTRITION IN INFANTS AND CHILDREN

    The quality o the evidence was rated as very low, as the absence o a control group in the reports

    o outpatient treatment o children with severe acute malnutrition and oedema make it difficult

    to make conclusions about the effectiveness and saety o outpatient treatment or children with

    oedema +/++. As a result, no GRADE table or this evidence base was developed.

    Discussion

    The guideline development group considered that the systematic review supported the general

    principle that severely malnourished children with oedema, but no other medical complications,

    can be effectively and saely treated as outpatients.

    It was also noted that the severity o oedema reported in children is inluenced by the

    amiliarity o the staff with seeing oedematous cases. Inexperienced staff have been observed

    to overestimate the extent o oedema.

    While data were not available to comment on the severity o oedema and the saety and effective-

    ness o managing children with severe malnutrition and oedema at home, the association oincreased mortality risk with more severe oedema (independent o site o care) was noted by

    the guideline group.

    The guideline group considered that evidence rom inpatient settings supported managing

    children with severe malnutrition who have oedema +++ as inpatients and those with oedema

    +/++ as outpatients.

    The guideline group noted, however, that caution is required in interpretation o these results,

    as there are limitations in the quality o the design o the included studies.

    Relevant standing recommendations

    The recommendations were conirmed as current in the context o existing WHO recommendations

    included in the WHO Management of severe malnutrition: a manual for physicians and other senior

    health workers, 1999 (2)and Joint United Nations statement on Community-based management of

    severe acute malnutrition, 2007 (10), noting in particular that:

    inants and children who have only + or ++ bilateral pitting oedema but present with medical

    complications or have no appetite should be admitted or inpatient care;

    inants above 6 months o age and children who have + or ++ bilateral pitting oedema but who

    have no medical complications and have appetite should be managed as outpatients;

    children with bilateral pitting oedema who are admitted or inpatient care should transition

    rom the stabilization to the transition phase when appetite returns and oedema is reducing.

    Recommendations

    2.1 Children with severe acute malnutrition who have severe bilateral oedema +++,1even i they

    present with no medical complications and have appetite, should be admitted or inpatient

    care.

    Rationale

    The guideline group noted that the quality o evidence was very low but was in consensus that

    the recommendation should be strong. The recommendation essentially makes explicit what ispresently implicit in existing WHO recommendations. The recommendation is thereore not new

    but clariies where children with severe bilateral oedema should be treated, i.e. in hospital. The

    recommendation prioritizes the saety o children with this complication. The recommendation

    is easible, as, in previous guidelines, all children with severe acute malnutrition were admitted.

    Hence, this recommendation places no additional cost burden on health systems than previously.

    Implications or uture research

    evidence available in themes related to the priority areas listed next.

    GUIDELINE: UPDATES ON THE MANAGEMENT OF SEVERE ACUTE MALNUTRITION IN INFANTS AND CHILDREN

    3. Use o antibiotics in the management o children withsevere acute malnutrition in outpatient care

    Preamble

    Epidemiological and clinical studies have documented the high prevalence o pneumonia,

    bacteraemia and urinary tract inections in children with severe acute malnutrition, which ofen

    may not be symptomatic.

    The WHO Management of severe malnutrition: a manual for physicians and other senior health

    workers, 1999 recommended that all children with severe acute malnutrition should be admitted

    to hospital and treated with a course o antibiotics (2). I clinical complications were present, then

    parenteral antibiotics were recommended, depending on local resistance patterns and availability.

    For children without obvious clinical sepsis, oral antibiotics were recommended. Because severe

    acute malnutrition suppresses the immune response, it is hard to detect inection.

    The availability o ready-to-use-therapeutic oods now allows large numbers o children who have

    severe acute malnutrition and are over 6 months o age, but who do not have medical complications,

    to be treated as outpatients. These children were previously treated in hospital because ready-to-

    use therapeutic oods that could be saely used in the community were not available. The 2007

    joint United Nations statement on Community-based management of severe acute malnutrition

    (10)recommends that, in addition to the provision o ready-to-use therapeutic ood, children with

    severe acute malnutrition receive a short course o basic oral medication to treat inections.

    In 2007, however, the evidence to support the use o oral antibiotics in children without signs o

    clinical sepsis was limited. The emergence o successul outpatient management o children who

    have severe acute malnutrition but do not demonstrate clinical complications, has raised the

    question o whether these children would beneit rom a course o oral antibiotics as par t o routinemanagement in line with WHOs 1999 recommendation or treatment in hospitals (2).

    The choice o antibiotic, or either inpatient or outpatient management, should consider patterns

    o antibiotic resistance, which vary between countries (52, 53); high rates o resistance to second-

    line antibiotics such as chloramphenicol, gentamicin and cephalosporins have been reported (52),

    while sensitivity to ciproloxacin remains generally high. In vitro resistance, however, does not

    necessarily relect clinical efficacy.

    The guideline development group aimed to update guidance on the ollowing question:

    Do children with uncomplicated severe acute malnutrition need to be treated with antibiotics

    and, i so, then which antibiotic should be used?

    Summary o the evidence

    A systematic review was conducted to examine the clinical saety and efficacy o antibiotic inter-

    ventions among children with uncomplicated severe acute malnutrition (54).

    One study reported outcomes in hospitalized children with severe acute malnutrition who all

    received antibiotics. In a randomized controlled trial (20022003), there were no signiicant

    differences in any o the efficacy outcomes among Sudanese children with severe acute malnutrition

    (complicated and uncomplicated) who were treated with either 5 days o oral amoxicillin or 2 days

    o intramuscular (IM) cefriaxone (55). Given that the study population was restr icted to hospitalized

    children and there was no control group, this study did not provide direct evidence on the saety

    and efficacy o antibiotics in children with uncomplicated severe acute malnutrition.

  • 8/10/2019 Who Reccomendation Malnutrition

    34/123

    27

    Two studies provided evidence on the efficacy o antibiotics in children managed as outpatients.

    In a retrospective analysis o children in Malawi with uncomplicated severe acute malnutrition

    managed as outpatients, outcomes in one cohort who received 7 days o oral amoxicillin in addition

    to ready-to-use therapeutic ood were compared with those o a cohort who received ready-to-use

    therapeutic ood only. At 12 weeks ollow-up, mortality rates were less than 5% in both cohorts

    and rates o nutritional recovery were similar (56). However, these two cohorts o children were

    quite different at baseline and thereore the results are difficult to interpret.

    In a prospective, randomized, double-blind trial in southern Malawi, children with uncomplicated

    severe acute malnutrition managed as outpatients were randomized to receive either 1 week o

    amoxicillin 8090 mg/kg/day, cedinir 14 mg/kg /day or placebo(57). The rate o nutritional recovery

    o children who received antibiotics was signiicantly better than that o those who received placebo

    (amoxicillin 89.0%, cedinir 91.4%, placebo 85.1%, P < 0.0002). This result was consistent among

    both children with bilateral oedema (amoxicillin 91.6%, cedinir 92.9%, placebo 88.3%, P< 0.007)

    and those with severe wasting (amoxicillin78.9%, cedinir 85.1%, placebo 73.7%, P< 0.03). Mortality

    rates were signiicantly lower in the groups that received antibiotics (amoxicillin 4.63%, cedinir

    3.86%, placebo 7.48%, P< 0.002). When analysed by type o malnutrition, mortality was reduced in

    children who had bilateral oedema (amoxicillin 3.49%, cedinir 3.56%, placebo 7.48%, P< 0.0006).

    However, the study was not speciically powered to undertake the latter analysis.

    One beore-and-afer study o ampicillin and gentamicin as second-line antibiotics was also identi-

    ied. The design o the study was such that it was not possible to estimate the relative effect o the

    introduction o the antibiotic regimen independently o an algorithm or managing hypoglycaemia

    that was introduced in parallel (58).

    No studies o cefriaxone, ciproloxacin or co-trimoxazole as a irst-line treatment or children with

    severe acute malnutrition were identiied.

    The overall quality o this evidence was rated as low, owing to methodological and reporting bias.

    SeeAnnex 1, Table 1or details o the GRADE assessment o the evidence.

    Discussion

    The guideline group considered that the use o broad-spectrum antibiotics such as amoxicillin

    or children with severe acute malnutrition is supported by epidemiological data demonstrating

    a high prevalence o inections in these children, including children with uncomplicated severe

    acute malnutrition receiving outpatient management.

    It is possible that providing antibiotics will result in some adverse events such as diarrhoea, skin

    reactions and hypersensitivities. However, it is unlikely that the requency o such complications

    will be signiicantly more than in well-nourished children.

    However, it was noted that the one randomized trial that speciically examined outcomes in this

    population was in a setting where the pattern o severe acute malnutrition is predominantly

    oedematous and HIV is also prevalent.

    Increased antimicrobial resistance is a potential consequence o prescribing broad-spectrum

    antibiotics or the outpatient treatment o children with severe acute malnutrition.

    However, children with severe acute malnutrition are at high risk o mortality higher or

    example, than inants with ast breathing, where antibiotics are also currently recommended.

    The reported reduction in mortality in children with uncomplicated severe acute malnutri-

    tion treated with antibiotics as outpatients (7.48% to 4.63%) is signiicant and the guideline

    group thought it was justiied to recommend this intervention to this population, even at the

    risk o increasing antimicrobial resistance in the community.

    GUIDELINE: UPDATES ON THE MANAGEMENT OF SEVERE ACUTE MALNUTRITION IN INFANTS AND CHILDREN

    Community-level antimicrobial resistance is not a certain consequence o providing

    antibiotics to children as part o outpatient care but will depend on actors that include the

    prevalence o uncomplicated severe acute malnutrition, the quality o health-care worker

    counselling and adherence to medications at home.

    Antimicrobial resistance o community-acquired inections may be already present and the

    consequence o antibiotic use or other reasons.

    Research is needed to examine these issues.

    It was noted that small bowel bacterial overgrowth is common in children with severe acute

    malnutrition and affects intestinal unction.

    The mechanism by which oral antibiotics may beneit children with uncomplicated severe

    malnutrition is unclear but may include reducing excessive prolieration o small bowel lora,

    translocation o gut bacteria into the bloodstream, or modiication o the microbiome.

    The cost o providing oral antibiotics to all children with uncomplicated severe acute mal-

    nutrition as outpatients would be about US$0.45 to US$0.60 per child or 5 days treatment (59).WHO guidelines previously recommended that all children with severe acute malnutrition

    should be admitted and all children given appropriate antibiotics (2). Hence, while guidelines

    have changed to provide treatment or these children in outpatient care, treating all children

    with antibiotics has been the standard o care. While the budget to pay or antibiotics may be

    different between hospital and primary health-care acilities, the total cost to the national

    health authority would theoretically not be different. It is likely that all children in hospital are

    indeed given antibiotics and hence this cost is real. Reports rom programmes indicate that

    the introduction o community-based screening has increased the identiication o children

    with severe acute malnutrition both those requiring hospital care and those that can be

    managed as outpatients. The unds required or antibiotics have thereore increased because

    o community-based screening improving coverage and service uptake. Managing children as

    outpatients is likely to be cheaper than hospital care, even i oral antibiotics are included as part

    o standard care. No cost analysis o these approaches was available.

    While providing antibiotics would increase the transaction time between health-care workers

    and mothers/caregivers o children, and highlights the importance o reliable supply-chain

    management, the potential reduction in mortality justiies these opportunity costs.

    WHO endorses the principle that antimicrobials should only be given to patients when

    inection is present. In the context o severe acute malnutrition, uncomplicated should not be

    understood to mean that inection is not present. Rather uncomplicated implies the absence

    o symptoms or inection and that the child can be otherwise managed as an outpatient.

    The guideline group noted that research is urgently needed to examine outcomes in populations

    where wasting predominates, such as in South-East Asia, and where HIV is less common.

    Relevant standing recommendations

    The recommendations were conirmed as current in the context o existing WHO recommendations

    included in the WHO Management of severe malnutrition: a manual for physicians and other senior

    health workers, 1999 (2), noting in particular that:

    children admitted with severe acute malnutrition and complications such as septic shock,

    hypoglycaemia, hypothermia, skin inections, or respiratory or urinary tract inections, or who

    appear lethargic or sickly, should be given parenteral (IM or intravenous [IV]) antibiotics;

    children admitted with severe acute malnutrition and with no apparent signs o inection andno complications should be given an oral antibiotic.

    The guideline group noted that the quality o evidence regarding the efficacy o antibiotics in children
