Therapeutic responses to AZT + 3TC + EFV in advanced antiretroviral naive HIV type 1-infected Ugandan patients.

Convenient, non-food-dependent dosing, low tablet volume, and relatively low cost have made nonnucleoside reverse transcriptase inhibitors a first choice for both clinicians and patients in Uganda. Concerns exist as to their efficacy in patients with viral loads (VL) above 100,000 copies/ml, a feature common to about 75% of HIV-1-infected patients presenting at the Joint Clinical Research Center (JCRC) in Uganda. Furthermore, there are few data on the response to such therapy of non-B subtypes, A and D, predominant in Uganda. Presented here is a retrospective analysis of therapeutic responses in 11 antiretroviral (ARV) naïve HIV-1-infected Ugandan patients who had been initiated on zidovudine (AZT), lamivudine (3TC), and efavirenz (EFV). Laboratory assessments subsequent to initiation of ARV therapy, done at 11.6 +/- 3.9 weeks and 30.6 +/- 5.9 weeks, showed 88.9 and 71.4% patients achieved undetectable viral load, respectively. Virological suppression to below detection occurred in 85.7% of patients at 11.6 weeks despite baseline VL >or= 100,000 copies/ml. At 31 weeks there was a median increment of +183 cells/mm(3) in CD4(+) T lymphocytes. These findings reflect significant efficacy in the use of AZT + 3TC + EFV in advanced ARV naive non-B subtype HIV-1-infected patients. The therapeutic responses were comparable to those previously described in the western world.

Reproductive intentions and outcomes among women on antiretroviral therapy in rural Uganda: a prospective cohort study.

BACKGROUND: Antiretroviral therapy (ART) may influence the biological, social and behavioral determinants of pregnancy in HIV-infected women. However, there are limited longitudinal data on the reproductive intentions and outcomes among women on ART in Africa. METHODOLOGY /PRINCIPAL FINDINGS: Using a prospective cohort design, we analyzed trends in desire for children and predictors of pregnancy among a cohort of 733 HIV-infected women in rural Uganda who initiated ART between May 2003 and May 2004 and were followed up in their homes until June 2006. Women answered in-depth social and behavioral questionnaires administered every quarter in year 1 after initiating ART, and every 6 to 12 months thereafter. Use of family planning methods was assessed at 18 and 24 months after starting ART. We tested for non-constant pregnancy incidence by using a shape parameter test from the Weibull distribution. We modeled repeated measurements of all variables related to the women's desire for children over time using a generalized estimating equation (GEE) extension to the logistic regression model. Risk factors for pregnancy were examined using Cox proportional hazards model. 711 women eligible for the study were followed-up for a median time of 2.4 years after starting ART. During this time, less than 7% of women reported wanting more children at any time point yet 120 (16.9%) women experienced 140 pregnancies and pregnancy incidence increased from 3.46 per 100 women-years (WY) in the first quarter to 9.5 per 100 WY at 24 months (p<0.0001). This was paralleled by an increase in the proportion of women reporting sexual activity in the past 3 months, from 24.4% at baseline to 32.5% over 24 months of follow-up (p = 0.001). Only 14% of women used permanent or semi-permanent family planning methods by their second year on ART. In the multivariate model, younger age (HR = 2.71 per 10-year decrease, 95% CI: 2.95-3.78), having a BMI>18.5 (HR = 1.09, CI: 1.01-1.18) and not having used condoms consistently in the last 3 months (HR = 1.79, CI: 1.02-3.13) were independently associated with pregnancy. CONCLUSION/SIGNIFICANCE: Women on ART and their partners should be consistently counseled on the effects of ART in restoring fertility, and offered regularly free and comprehensive family planning services as part of their standard package of care.
