Children with neurological deficits Convenience sample

3 clinic days: 2 in Mrauk Oo, 1 in Sittwe Simple histories & physical information via

an interpreter 17 cases of neurological deficits

Out of 48 children seen

Page 17: Acute encephalitis syndrome in Rakhine State

Children with neurological deficits Mild cases

Hand or foot weakness Severe cases

Global developmental delay Speech/language deficits Intellectual deficits Gross motor deficits

Page 18: Acute encephalitis syndrome in Rakhine State

Children with neurological deficits Generally described as developing

normally prior to illness History of febrile illness

7 – 10 days duration “unconscious” during illness

Neurological deficits subsequently

Health services in rural areas of Rakhine State Rudimentary to non-existent

Most parents described caring for children during acute encephalitis (brain infection) syndrome at home

Diagnostic capabilities limited Specific diagnoses not made

Acute encephalitis syndrome WHO definition: acute onset of fever and

altered mental status new onset of seizures, or both

1,578 enrolled patients, Japanese encephalitis virus JEV (16.2%) dengue virus DV (10.8%) herpes simplex virus HSV (9.3%) measles virus (8.9%) mumps virus (8.7%) varicella zoster virus VZV (4.4%) enterovirus (0%)

Page 28: Acute encephalitis syndrome in Rakhine State

In Assam 223 hospitalized AES cases: 30% JE positive Among the JE patients: 15% died before discharge 64% complete recoveries 21% had some sort of disability at the time of discharge.

From: Richard Yanagihara Date: Thu, Jan 29, 2015 at 9:19 AM Subject: Re: neurologic sequelae of febrile illness among children in Western Myanmar To: Seiji Yamada <[email protected]> Cc: Vivek Nerurkar, Pamela Bullard, Sandra Chang The situation you mention has dogged clinicians for many years in southeast Asia. Clearly better diagnostics are needed to find the causative agent for acute neurological diseases of unknown etiology. Japanese encephalitis virus is a possibility, but other yet-to-be-discovered neurotropic viruses should also be explored.

Page 30: Acute encephalitis syndrome in Rakhine State
Page 31: Acute encephalitis syndrome in Rakhine State

A mosquito-borne disease 20%–30% case-fatality rate 30%–50% of survivors neurologic or psychiatric sequelae

Risk is highest in rural, agricultural areas

Occurs mainly among children aged ≤15 years No specific treatment for JE is available. Vaccination is the single most important preventive measure

Page 32: Acute encephalitis syndrome in Rakhine State

Myanmar does not have an immunization program. WHO recommends that JE vaccination be extended to all areas where JE is a public health problem The most effective immunization strategy is a one-time campaign in the target population . . . followed by incorporation of JE vaccine into routine childhood immunization

Page 33: Acute encephalitis syndrome in Rakhine State

Live attenuated SA14-14-2 vaccine simple schedule good safety profile improved international availability

Chengdu Institute of Biological Products

has guaranteed a low public sector price for lower-income countries

Rakhine State children with neurological deficits Large numbers of children with

neurological deficits A consequence of acute encephalitis

syndrome Causative agents not understood Needs to be studied from microbiological,

epidemiological perspectives

Page 35: Acute encephalitis syndrome in Rakhine State

Rakhine State children with neurological deficits

Regional literature points to some role played by Japanese encephalitis

Vaccination for Japanese encephalitis should be instituted in Myanmar
