1 Predictors of Immunological Failure Among Adult Patients Receiving ART at an urban, HIV Clinic in Uganda Dr. Muhumuza Simon (M.D, MPH) Mulago-Mbarara Teaching Hospitals’ Joint AIDS Program [MJAP] 16 th International Conference on AIDS & STIs in Africa (ICASA 2011) Addis Ababa, Ethiopia, December 4-8, 2011
In recent years, there has been a rapid scale up of HAART in resource limited settings In Uganda, ART coverage is ~ 50% (290,000) Monitoring patients on ART remains a challenge Most ART centers use immunological criteria (CD4 cell count) to monitor HIV treatment success 2
Established in November 2004 with funding from CDC-PEPFAR Supports provision of comprehensive HIV/AIDS services in 2 National Referral Hospitals and 11 HIV clinics Currently, the program supports > 29,000 patients on ART (~ 10% of the national ART coverage) ~ 97% of ART patients are on first line treatment 3

5 To determine factors associated with immunological failure among adult patients receiving HAART
Retrospective cohort analysis of data of 5,306 patients at Mulago ISS clinic between , on 1 st line treatment for 1 year Immunological failure was defined as having a CD4 cell count < pre-therapy value after 1 year on HAART This was compared to the patients demographics, pre- therapy CD4 count, WHO stage, HAART regimen, mean adherence levels and incidence of OIs 6

Immunological failure is significantly associated with: * Male gender * Age < 35 years * ARV regimen (NVP based) * Adherence level (<95%) * Pre-therapy CD4 count * WHO stage 12
HIV care and treatment programs should emphasize adherence during each patient encounter - Male gender -Young patients EFV should be preferred against NVP as a 1 st line drug Early HIV testing and linkage to care before severe immunosuppression develops is critical 13
