Objective To describe the burden of pediatric tuberculosis (TB) in a human immunodeficiency virus (HIV)-infected population and explore the demographic and clinical factors associated with the occurrence of pediatric TB. Design Longitudinal analysis of a cohort of HIV-infected children. Methods The endpoint of the study was clinically diagnosed TB. Cox proportional hazard regression was used to explore the predictors of incident TB among HIV-infected children under age 15 years after enrollment into the HIV program. Results The cohort comprised of 5040 children [median age: 5 years, interquartile range (IQR): 1–9 years]. During a median follow-up of 0.8 (IQR: 0.1–2.5) years, 376 out of 5040 children met the case definition for TB. The overall incidence of TB was 5.2/100 person-years. In multivariate analyses, older age at enrollment [relative risk (RR): 1.7, 95%, confidence interval (CI): 1.5–1.8], severe wasting (RR: 1.8, 95% CI: 1.3 –2.5), severe immune-suppression (RR: 2.6, 95% CI: 1.8–3.8), anemia (RR: 1.4, 95% CI: 1.0–1.9) and World Health Organization (WHO) stage IV (RR: 4.5, 95% CI: 2.4–8.5) were all independently associated with a higher risk of TB. In addition, the use of antiretroviral drugs for more than 180 days reduced the risk of TB by 70% (RR: 0.3, 95% CI: 0.2–0.4). Conclusions ART use is strongly associated with a reduced risk of tuberculosis among HIV-infected children, and should therefore be included in HIV care and treatment programs. Trials of interventions designed to improve the nutritional and hematologic status of these children should also be performed.
Targeted interventions should be developed to improve ART adherence among healthier, younger, and more experienced patients who are on ART for longer durations within HIV care and treatment programs. Social support for patients on ART should be emphasized.
Background Overweight and obesity are increasingly prevalent among HIV-infected populations. We describe their prevalence and associated risk factors among HIV-infected adults in Dar es Salaam, Tanzania. Methods A cross-sectional study was conducted to determine the proportion of patients who were overweight or obese at enrollment to care and treatment centres from 2004 to 2011. Multivariate relative risk regression models were fit to identify risk factors. Results A total of 53 825 patients were included in the analysis. In all, 16% of women and 8% of men were overweight, while 7% and 2% were obese, respectively. In multivariate analyses, older age, higher CD4 count, higher hemoglobin levels, female sex, and being married were associated with obesity and overweight. World Health Organization HIV disease stage, tuberculosis history, and previous antiretroviral therapy were inversely associated with obesity and overweight. Conclusion Overweight and obesity were highly prevalent among HIV-infected patients. Screening for overweight and obesity and focused interventions should be integrated into HIV care.
ObjectiveFemale bar workers (FBW) in East Africa often conduct sex work to supplement their incomes, and may be vulnerable to HIV acquisition. Pre-exposure prophylaxis (PrEP) offers protection against HIV acquisition. However, there is little research on FBW’s sexual health. Our objective was to determine HIV risk behaviours and interest in PrEP among FBW in the largest city in East Africa.DesignCross-sectional survey covering respondents’ work and personal lives, including social and behavioural risk factors for HIV. The survey aimed to determine the feasibility of working with FBW and HIV prevalence estimates. Those who did not report being HIV positive were asked about their knowledge of and interest in PrEP. All women were offered free on-site HIV testing and counselling (HTC).SettingEight randomly selected workplaces, that is, bars, in Kinondoni district, Dar es Salaam (DSM).Participants66 FBW (≥18 years) selected at random from all women working in selected bars on the day of visit.ResultsHalf of respondents reported having had sex for money: 20% with bar clients only, 15% with other men only and 15% with both. Almost all (98%) reported ≥1 non-commercial partners in the past 12 months; only 30% reported using condoms with these partners. 85% of respondents had ever been pregnant; 44% had had an unintended pregnancy. Only 5% of respondents had ever heard of PrEP. However, 54% were somewhat/very interested in daily-pill PrEP and 79% were somewhat/very interested in long-acting injectable PrEP. When asked to rank modalities, long-acting injectable PrEP was the most preferred. Seven per cent of the 56 respondents who completed HTC tested HIV positive.ConclusionsFBW in DSM have elevated risk factors for HIV acquisition, and PrEP appears highly acceptable. Studies developing PrEP delivery models and assessing PrEP initiation and adherence in FBW appear warranted.
Maternal mortality was high among HIV-infected women. Initiating women on antiretroviral therapy as early as possible and providing nutritional interventions during pregnancy should be considered as means to reduce the maternal mortality among these women.
