Abstract

Introduction: Anemia is a common problem in HIV in sub-Saharan Africa. We describe the contribution of antiretroviral therapy (ART) regimen to the incidence of anemia and changes in hemoglobin (Hb) in HIV-infected patients in Uganda.

Methods: This study was nested in a prevention of cryptococcal disease trial (CRYPTOPRO; ISCRTN7648152). Patients received 3 different backbones of nucleoside reverse transcriptase inhibitor in a nonrandomized manner.

Results: Of the 852 patients (161 on zidovudine [ZDV], 628 on stavudine [d4T], and 63 on tenofovir [TDF]; all received lamuvidine), the risk of developing grade 4 anemia was higher (adjusted hazard ratio 2.7) for those receiving ZDV than those receiving d4T. Those receivingd4T had a higher average increase in Hb than those receiving ZDV (P = .024) or TDF (P = .014).

Conclusion: In this observational study, ZDV was associated with severe anemia compared to d4T or TDF; those receiving ZDV and TDF had smaller increases in Hb after ART initiation. We encourage publication of data on cohorts using TDF from Africa.
