ABSTRACT
Presentation to care with advanced HIV disease (AHD) is a significant problem in Sub-Saharan Africa. We evaluated factors associated with immune recovery among individuals presenting to care with AHD in Zimbabwe. We conducted a retrospective evaluation of outcomes among adult (>18 years old) individuals with AHD (CD4 count ≤ 200 cells/mm3) receiving care at 18 outpatient primary care clinics in Harare, Zimbabwe. Baseline and 12-month CD4 count data were extracted from medical records. CD4 count recovery (defined as CD4 count > 200 cells/mm3) after 12 months on NNRTI-based antiretroviral therapy (ART) regimen was determined and factors associated with CD4 count recovery were established using logistic regression. All statistical analysis was performed on SPSS v23. A total of 1338 participant records were included in the analysis. The median interquartile range (IQR) age was 37 (30-43) years and 52% were females. The baseline median (IQR) CD4 count was 50 (28-75) cells/mm3 and was significantly lower among patients with history of cryptococcal meningitis compared to those without (25(10-52) vs 52(32-77), respectively; p=0.0009). The median (IQR) CD4 count at 12 months after ART initiation increased from 50 (28-75) at baseline to 180 (92-290) cells/mm3. Immune recovery with a CD4 count > 200 cells/mm3, was observed in 181/417 (43%). Male gender and low baseline CD4 count were strong predictors of poor immunological recovery on ART. Immunological recovery following ART initiation was 43% among individuals with AHD. Male patients are most vulnerable to persistent immunological failure.
