The Newlands Clinic (NC)

• A Public Private Partnership with AIDS & TB unit in MOHCC

• Commenced operations in 2004 offering free, comprehensive HIV care & treatment for over 5000 patients: lab & pharmacy, diagnosis & management of OIs including TB, women’s health service (WHS), pyscho-social programme, adolescent corner & a nutrition programme

• Nurse-led model of care3

The Newlands Clinic (NC)

• Training school: o National Advanced HIV Management for

Adults & Children o Visual Inspection with Acetic Acid &

Cryotherapy (VIAC) training

• Partner in the National VIAC programme

4

The Newlands Clinic WHS

• Launched in January 2011 to offer cervical cancer screening, STI diagnosis & treatment for all sexually active female patients registered at NC

• Currently 2550 females > 18 years of age in

care

• Nurse-led service supervised by Dr Magure (UZ Dept O&G)

5

The Newlands Clinic WHS

• ‘See & treat’ approach – VIAC & cryotherapy

• Loop Electrosurgical Excision Procedure (LEEP) for more advanced lesions

• Referral system for patient’s requiring complicated surgical procedures eg TAH

Screening for Cervical Abnormality

• Cytology (pap smear)

• Visual methods (VIAC, VILI)

• HPV DNA testing – screen for high risk HPV types, not recommended for routine practise

Normal Cervix

Normal Cervix

VIA Positive

VIAC Positive

VIAC Positive

Invasive cervical cancer

Case Study 1 – Mrs EC

• 49 years old• Commenced ART in January 2005 (9½ years)• On 1st line (TDF/3TC/NVP)• Baseline CD4 count 83, June 2014 573

• Viral load undetectable since April 200515

Mrs EC - routine VIAC screening in April 2012

16

LEEP:histology - koilocytosis

VIAC positive: eligible for LEEP

Mrs EC – VIAC screening April 2013

17

VIAC positive - eligible for LEEP

Histology – micro-invasive carcinoma of the cervix

Mrs EC - outcome

• TAH done at Karanda Mission Hospital in Dec 2013

• Histology confirmed micro-invasive carcinoma of the cervix

• Reviewed in WHS June 2014 – all well• For repeat VIAC (vaginal vault Dec 2014)

18

Case study 2 – Ms MM

• 19 year old • Commenced ART in March 2005 (at 10 years

of age)• Baseline CD4 was 224, June 2014 was 710

• Viral load undetectable19

Ms MM – routine VIAC screening August 2014

VIAC positive – eligible for LEEP

LEEP done 13/08/2014 – CIN I

HIV, HPV and Cervical Cancer

• >140 HPV types identified, 40 infect female genital tract & 18 (incl types 16 & 18) are high risk for oncogenesis

• Pre-existing HPV infection is associated with a 2-fold increase in the risk of HIV acquisition in women (1)

• It has been recognized that HIV+ve people: - more likely to have HPV - carry ↑ number of HPV types - less likely to spontaneously clear HPV infection

• HIV changes the natural history of HPV infection → 10 fold ↑ incidence of cervical dysplasia & 5 fold ↑ incidence of cervical neoplasia

• HIV causes chronic inflammation – markers present in blood and urine (2)

• Recurrence rates of HPV infection are higher in HIV+ve women than in HIV-ve women

• HIV+ve women with a low CD4 count are more likely to experience progression of cervical cancer

• ARV’s will prolong the life of women infected with HPV & allow the development of cervical cancer

HPV infection in HIV+ve Women

HPV infection in HIV+ve Women

The most common types of lower genital tract disease caused by HPV infection in HIV+ve women:• Cervical intraepithelial neoplasia (CIN)• Genital warts• Vulval intraepithelial neoplasia• Anal intraepithelial neoplasia• Vaginal intraepithelial neoplasia• Cervical cancer• Anal cancer 23

Purpose of the record review

The purpose of this review was: • To establish the prevalence of VIAC

positive lesions at initial screening in women registered in care at NC

• To determine the histological diagnosis in women with VIAC positive lesions undergoing the LEEP procedure

24

Methodology

• A record review of patients undergoing initial cervical screening from January 2011 to December 2013 was done

• The percentage of VIAC positive lesions was assessed

• Histological specimens obtained from 235 LEEP procedures were analysed

25

Results

• The age range of women with VIAC positive lesions screened was 18 – 63 years

• The % of women with VIAC positive lesions was:

- 2011 - 34.9% (314/899) - 2012 - 30.1% (269/895) - 2013 - 31.0% (126/406)• The mean over the 3 years was 32.0% 26

Results

Histological diagnosis for 235 LEEP specimens confirmed pre-cancerous lesions in 69%

• CIN I - 12%• CIN II - 27%• CIN III - 30% • Cervical cancer in 2%

27

Histological Diagnosis

28

CIN I 12%

CIN II 27%

CIN III 30%

HPV-related changes 17%

Cervical Cancer 2%

Other 12%

Conclusions

• These data illustrate a 32% prevalence of VIAC positive lesions

• Histological diagnosis confirmed moderate to severe dysplasia (CIN II and III) in 57% and invasive cancer in 2%

• Cervical screening, plus appropriate treatment, is an essential component of care for HIV-infected women in care at Newlands Clinic

Recommendations

• VIAC must be introduced as standard of care for all HIV+ve women in Zimbabwe

• In order to prevent HPV infection & consequent cervical disease, pre-adolescent girls must be vaccinated (3)

• Due to the parallel epidemics of HPV & HIV in Zimbabwe, we should consider HPV vaccination as a additional preventive strategy for pre-adolescent girls, in an attempt to reduce the acquisition of HIV in this key population (3)
