Abstract

Background: Because men in Africa are less likely to access HIV/AIDS care than women, we aimed to determine if men have differing outcomes from women across a nationally representative sample of adult patients receiving combination antiretroviral therapy in Uganda. Methods: We estimated survival distributions for adult male and female patients using Kaplan‐Meier, and constructed multivariable regressions to model associations of baseline variables with mortality. We assessed person‐years of life lost up to age 55 by sex. To minimize the impact of patient attrition, we assumed a weighted 30% mortality rate among those lost to follow up. Results: We included data from 22,315 adults receiving antiretroviral therapy. At baseline, men tended to be older, had lower CD4 baseline values, more advanced disease, had pulmonary tuberculosis and had received less treatment follow up (all at p < 0.001). Loss to follow up differed between men and women (7.5 versus 5.9%, p < 0.001). Over the period of study, men had a significantly increased risk of death compared with female patients (adjusted hazard ratio 1.43, 95% CI 1.31‐1.57, p < 0.001). The crude mortality rate for males differed importantly from females (43.9, 95% CI 40.7‐47.0/1000 person‐years versus 26.9, 95% CI 25.4‐28.5/1000 person years, p < 0.001). The probability of survival was 91.2% among males and 94.1% among females at 12 months. Person‐years of life lost was lower for females than males (689.7 versus 995.9 per 1000 person‐years, respectively). Conclusions: In order to maximize the benefits of antiretroviral therapy, treatment programmes need to be gender sensitive to the specific needs of both women and men. Particular efforts are needed to enroll men earlier into care., Background Although the global prevalence of HIV among women has remained stable at 50%, in sub‐Saharan Africa, it is markedly higher in females than in males [1].

Abstract

Introduction: As access to antiretroviral therapy (ART) increases, the success of treatment programmes depends on ensuring high patient retention in HIV care. We examined retention and attrition among adolescents in ART programmes across clinics operated by The AIDS Support Organization (TASO) in Uganda, which has operated both facility- and community-based distribution models of ART delivery since 2004. Methods: Using a retrospective cohort analysis of patient-level clinical data, we examined attrition and retention in HIV care and factors associated with attrition among HIV-positive adolescents aged 10-19 years who initiated ART at 10 TASO clinics between January 2006 and December 2011. Retention in care was defined as the proportion of adolescents who had had at least one facility visit within the six months prior to 1 June 2013, and attrition was defined as the proportion of adolescents who died, were lost to follow-up, or stopped treatment. Descriptive statistics and Cox proportional hazards regression models were used to determine the levels of retention in HIV care and the factors associated with attrition following ART initiation. Results: A total of 1228 adolescents began ART between 2006 and 2011, of whom 57% were female. The median duration in HIV care was four years (IQR = 3-6 years). A total of 792 (65%) adolescents were retained in care over the five-year period; 36 (3%) had died or transferred out and 400 (32%) were classified as loss to follow-up. Factors associated with attrition included being older (adjusted hazard ratio (AHR) = 1.38, 95% confidence interval (CI) 1.02- 1.86), having a higher CD4 count (250+ cells/[mm.sup.3]) at treatment initiation (AHR =0.49, 95% CI 0.34-0.69) and HIV care site with a higher risk of attrition among adolescents in Gulu (AHR = 2.26; 95% CI 1.27-4.02) and Masindi (AHR =3.30, 95% CI 1.87-5.84) and a lower risk of attrition in Jinja (AHR =0.24, 95% CI 0.08-0.70). Having an advanced WHO clinical stage at initiation was not associated with attrition. Conclusions: We found an overall retention rate of 65%, which is comparable to rates achieved by TASO's adult patients and adolescents in other studies in Africa. Variations in the risk of attrition by TASO treatment site and by clinical and demographic characteristics suggest the need for early diagnosis of HIV infection, use of innovative approaches to reach and retain adolescents living with HIV in treatment and identifying specific groups, such as older adolescents, that are at high risk of dropping out of treatment for targeted care and support.

Abstract

Background: We compared clinical outcomes among HIV-infected participants receiving ART who were randomized to viral load (VL) and CD4 cell count monitoring in comparison to CD4 cell count monitoring alone in Tororo, Uganda.Methods: Beginning in May 2003, participants with CD4 cell counts <250 cells/μL or WHO stage 3 or 4 disease were randomized to clinical monitoring alone, clinical monitoring plus quarterly CD4 cell counts (CD4-only); or clinical monitoring, quarterly CD4 cell counts and quarterly VL testing (CD4-VL). In 2007, individuals in clinical monitoring arm were re-randomized to the other two arms and all participants were followed until March 31, 2009. We used Cox Proportional Hazard models to determine if study arm was independently associated with the development of opportunistic infections (OIs) or death.Results: We randomized 1211 participants to the three original study arms and 331 surviving participants in the clinical monitoring arm were re-randomized to the CD4-VL and CD4 only arms. At enrolment the median age was 38 years and the median CD4 cell count was 134 cells/μL. Over a median of 5.2 years of follow-up, 37 deaths and 35 new OIs occurred in the VL-CD4 arm patients, 39 deaths and 42 new OIs occurred in CD4-only patients. We did not observe an association between monitoring arm and new OIs or death (AHR =1.19 for CD4-only vs. CD4-VL; 95 % CI 0.82-1.73).Conclusion: We found no differences in clinical outcomes associated with the addition of quarterly VL monitoring to quarterly CD4 cell count monitoring.

Abstract

Background: Tuberculosis (TB) disease affects survival among HIV co-infected patients on antiretroviral therapy (ART). Yet, the magnitude of TB disease on mortality is poorly understood. Methods: Using a prospective cohort of 22,477 adult patients who initiated ART between August 2000 and June 2009 in Uganda, we assessed the effect of active pulmonary TB disease at the initiation of ART on all-cause mortality using a Cox proportional hazards model. Propensity score (PS) matching was used to control for potential confounding. Stratification and covariate adjustment for PS and not PS-based multivariable Cox models were also performed. Results: A total of 1,609 (7.52%) patients had active pulmonary TB at the start of ART. TB patients had higher proportions of being male, suffering from AIDS-defining illnesses, having World Health Organization (WHO) disease stage III or IV, and having lower CD4 cell counts at baseline (p < 0.001). The percentages of death during follow-up were 10.47% and 6.38% for patients with and without TB, respectively. The hazard ratio (HR) for mortality comparing TB to non-TB patients using 1,686 PS-matched pairs was 1.37 (95% confidence interval [CI]: 1.08--1.75), less marked than the crude estimate (HR = 1.74, 95% CI: 1.49--2.04). The other PS-based methods and not PS-based multivariable Cox model produced similar results. Conclusions: After controlling for important confounding variables, HIV patients who had TB at the initiation of ART in Uganda had an approximate 37% increased hazard of overall mortality relative to non-TB patients.

Abstract

Objective: Although international guidelines recommend initiating antiretroviral therapy (ART) when a patient's CD4 cell count is ≤350 cells/μL, most patients in resource-limited settings present with much lower CD4 cell counts. The lowest level that their CD4 cell count reaches, the nadir, may have long-term consequences in terms of mortality. We examined this health state in a large cohort of HIV+ patients in Uganda. Design: This was an observational study of HIV patients in Uganda aged 14 years or older, who were enrolled in 10 major clinics across Uganda. Methods: We assessed the CD4 nadir of patients, using their CD4 cell count at initiation of ART, stratified into categories (<50, 50-99, 100-149, 150-249, 250+ cells/μL). We constructed Kaplan-Meier curves to assess the differences in survivorship for patients left-censored at 1 year and 2 years after treatment initiation. We used Cox proportional hazards regression to model the associations between CD4 nadir and mortality. We adjusted mortality for loss-to-follow-up. Results: Of 22,315 patients, 20,129 patients had greater than 1 year of treatment follow-up. Among these patients, 327 (1.6%) died and 444 (2.2%) were lost to follow-up. After left-censoring at one year, relative to lowest CD4 strata, patients with higher CD4 counts had significantly lower rates of mortality (CD4 150-249, hazard ratio [HR] 0.60, 95% confidence interval [CI]: 0.45-0.82, P = 0.001; 250+, HR 0.66, 95% CI, 0.44-1.00, P = -0.05). Male sex, older age, and duration of time on ART were independently associated with mortality. When left-censoring at 2 years, CD4 nadir was no longer statistically significantly associated with mortality. Conclusion: After surviving for 1 year on ART, a CD4 nadir was strongly predictive of longer-term mortality among patients in Uganda. This should argue for efforts to increase engagement with patients to ensure a higher CD4 nadir at initiation of treatment. [ABSTRACT FROM AUTHOR]

Abstract

Background: Because men in Africa are less likely to access HIV/AIDS care than women, we aimed to determine if men have differing outcomes from women across a nationally representative sample of adult patients receiving combination antiretroviral therapy in Uganda. Methods: We estimated survival distributions for adult male and female patients using Kaplan-Meier, and constructed multivariable regressions to model associations of baseline variables with mortality. We assessed person-years of life lost up to age 55 by sex. To minimize the impact of patient attrition, we assumed a weighted 30% mortality rate among those lost to follow up. Results: We included data from 22,315 adults receiving antiretroviral therapy. At baseline, men tended to be older, had lower CD4 baseline values, more advanced disease, had pulmonary tuberculosis and had received less treatment follow up (all at p < 0.001). Loss to follow up differed between men and women (7.5 versus 5.9%, p < 0.001). Over the period of study, men had a significantly increased risk of death compared with female patients (adjusted hazard ratio 1.43, 95% CI 1.31-1.57, p < 0.001). The crude mortality rate for males differed importantly from females (43.9, 95% CI 40.7-47.0/1000 person-years versus 26.9, 95% CI 25.4-28.5/1000 person years, p < 0.001). The probability of survival was 91.2% among males and 94.1% among females at 12 months. Person-years of life lost was lower for females than males (689.7 versus 995.9 per 1000 person-years, respectively). Conclusions: In order to maximize the benefits of antiretroviral therapy, treatment programmes need to be gender sensitive to the specific needs of both women and men. Particular efforts are needed to enroll men earlier into care.
