An observational study in an urban Ugandan clinic comparing virological outcomes of patients switched from first-line antiretroviral regimens to second-line regimens containing ritonavir-boosted atazanavir or ritonavir-boosted lopinavir.

BACKGROUND: The World Health Organisation approved boosted atazanavir as a preferred second line protease inhibitor in 2010. This is as an alternative to the current boosted lopinavir. Atazanavir has a lower genetic barrier than lopinavir. We compared the virological outcomes of patients during the roll out of routine viral load monitoring, who had switched to boosted second- line regimens of either atazanavir or lopinavir. METHODS: This was a cross-sectional study involving adult patients at the Infectious Diseases Institute Kampala, Uganda started on a standard WHO recommended second-line regimen containing either boosted atazanavir or boosted lopinavir between 1 Dec 2014 and 31 July 2015.. Mantel -Haenszel chi square was used to test for the statistical significance of the odds of being suppressed (VL < 400 copies/ml) when on boosted atazanavir compared to boosted lopinavir after stratifying by duration on antiretroviral therapy (ART). Multivariate logistic regression analysis used to determine if the type of boosted protease inhibitor (bPI) was associated with virological outcome. RESULTS: Ninety (90) % on ATV/r and 83% on LPV/r had a VL less than 1000 copies/ml. The odds of being suppressed using the same viral load cut-off while on boosted atazanavir compared to boosted lopinavir was not statistically significant after stratifying for duration on ART (p = 0.09). In a multivariate analysis the type of bPI used was not a predictor of virological outcome (p = 0.60). CONCLUSIONS: Patients using the WHO recommended second-line of boosted atazanavir have comparable virological suppression to those on boosted lopinavir

Cryptococcal Antigenemia in Human Immunodeficiency Virus Antiretroviral Therapy-Experienced Ugandans With Virologic Failure.

BACKGROUND: Detectable serum or plasma cryptococcal antigen (CrAg) precedes symptomatic cryptococcal meningitis. The World Health Organization recommends CrAg screening for human immunodeficiency virus-positive persons with CD4 count <100 cells/μL initiating antiretroviral therapy (ART). However, an increasing proportion of patients with cryptococcosis are now ART experienced. Whether CrAg screening is cost-effective in those with virologic failure is unknown. METHODS: We retrospectively performed nationwide plasma CrAg testing among ART-experienced Ugandan adults with virologic failure (≥1000 copies/mL) using leftover plasma after viral load testing during September 2017-January 2018. For those who were CrAg positive, we obtained ART history, meningitis occurrence, and 6-month survival via medical records review. RESULTS: Among 1186 subjects with virologic failure, 35 (3.0%) were CrAg positive with median ART duration of 41 months (interquartile range, 10-84 months). Among 25 subjects with 6-month outcomes, 16 (64%) survived, 7 (28%) died, and 2 (8%) were lost. One survivor had suffered cryptococcal meningitis 2 years prior. Two others developed cryptococcal meningitis and survived. Five survivors were known to have received fluconazole. Thus, meningitis-free survival at 6 months was 61% (14/23). Overall, 91% (32/35) of CrAg-positive persons had viral load ≥5000 copies/mL compared with 64% (735/1151) of CrAg-negative persons (odds ratio, 6.0 [95% confidence interval, 1.8-19.8]; P = .001). CrAg prevalence was 4.2% (32/768) among those with viral loads ≥5000 copies/mL and 0.7% (3/419) among those with viral loads <5000 copies/mL. CONCLUSIONS: In addition to the CD4 threshold of <100 cells/μL, reflexive CrAg screening should be considered in persons failing ART in Uganda with viral loads ≥5000 copies/mL

Effects of rural–urban residence and education on intimate partner violence among women in Sub-Saharan Africa : a meta-analysis of health survey data

BACKGROUND: Intimate Partner Violence (IPV) against women is a major public health and human rights problem worldwide. Sub-Saharan Africa (SSA) has one of the highest prevalence of IPV against women in the world. This study used meta-analysis to obtain pooled rural–urban and education attainment differences in the prevalence of IPV among ever-partnered women in SSA, and assessed whether the differences in IPV depended on the SSA region or period or women’s age. METHODS: We analysed IPV data on 233,585 ever-partnered women aged 15–49 years from 44 demographic and health surveys conducted between 2000 and 2018 in 29 SSA countries. Random-effects meta-analyses were used to estimate overall rural–urban residence and educational differences in IPV rates among the women in SSA. Subgroup analyses were also done to investigate the sources of heterogeneity in the overall meta-analysis findings. RESULTS: The pooled prevalence of intimate partner violence was estimated to be 41.3% (37.4–45.2%). Regionally, the highest prevalence of IPV was in Middle Africa (49. 3%; 40.32–58.45), followed by East Africa (44.13%; 36.62–51.67), Southern Africa (39.36%; 34.23–44.49), and West Africa (34.30%; 27.38–41.22). The risks of experiencing IPV were significantly higher if the women had less than secondary education (RR=1.12; 95% CI 1.07–1.22) compared to those with at least a secondary education. Generally, women who resided in a rural area had their risks of experiencing IPV increased (RR=1.02; CI 0.96–1.06) compared to those who resided in urban areas, but the IPV increases were only significant in East Africa (RR=1.13; CI 1.07–1.22). CONCLUSION: In sub-Saharan Africa, intimate partner violence against women is widespread, but the levels are much higher among women with lower levels of education and residing in rural areas. Our findings have provided additional support to policies aimed at achieving SDG goals on the elimination of all forms of violence against women and girls in sub-Saharan Africa. For example, policies that advocate improved educational attainment, especially among women and communities in rural areas.Additional file 1: Figure A1: Prevalence of any IPV among women aged 15–49 years according to women’s residence type in each country and year.

Perceptions and Attitudes Toward an Interactive Voice Response Tool (Call for Life Uganda) Providing Adherence Support and Health Information to HIV-Positive Ugandans: Qualitative Study.

BACKGROUND: The continuing decline in AIDS-related deaths in the African region is largely driven by the steady scale-up of antiretroviral therapy. However, there are challenges to retaining people living with HIV on treatment. Call for Life Uganda (CFLU) is an interactive voice response tool using simple analogue phones. CFLU supports patients with daily pill reminders, preappointment reminders, symptom reporting and management, and weekly health promotion tips. Mobile health tools are being increasingly used in resource-limited settings but are often adopted without rigorous evaluation. OBJECTIVE: This qualitative study conducted at 12 months after enrollment assessed patients' experiences, perceptions, and attitudes regarding CLFU. METHODS: We conducted a qualitative substudy within an open-label randomized controlled trial titled "Improving outcomes in HIV patients using mobile phone based interactive software support." Data were collected through 6 focus group discussions with participants sampled based on proportion of calls responded to-50%-conducted at the Infectious Diseases Institute, Mulago, and the Kasangati Health Centre IV. NVivo (version 11; QSR International) was used in the management of the data and in the coding of the emerging themes. The data were then analyzed using content thematic analysis. RESULTS: There was consensus across all groups that they had more positive than negative experiences with the CFLU system. Participants who responded to >50% of the calls reported more frequent use of the specific elements of the CFLU tool and, consequently, experienced more benefits from the system than those who responded to calls less frequently. Irrespective of calls responded to, participants identified pill reminders as the most important aspect in improved quality of life, followed by health promotion tips. The most common challenge faced was difficulty with the secret personal identification number. CONCLUSIONS: Findings showed participants' appreciation, high willingness, and interest in the intervention, CFLU, that demonstrated great perceived potential to improve their access to health care; adherence to treatment; health awareness; and, consequently, quality of life.

Comparing adherence to MDR-TB treatment among patients on self-administered therapy and those on directly observed therapy: non-inferiority randomized controlled trial.

BACKGROUND: Adherence is key to the treatment success of multi-drug resistant tuberculosis (MDR-TB) and prevention of community transmission. Directly observed therapy (DOT) is the recommended approach for the management of patients with MDR-TB. Uganda implements a health facility-based DOT approach where all patients diagnosed with MDR-TB report to the nearest private or public health facility for daily observation of ingesting their medicines by a health care provider. Directly observed therapy is very costly for both the patient and health care system. It follows the assumption that MDR TB patients have a history of poor adherence to TB treatment. But only 21% of MDR-TB patients notified globally and 1.4-12% notified in Uganda had been previously treated for TB. The shift to all oral treatment regimen for MDR-TB provides an opportunity for the exploration of self-administered therapy for this group of patients even with use of remotely operated adherence technology. We are conducting a non-inferiority open-label randomized controlled trial to compare adherence to MDR-TB treatment among patients on self-administered therapy (measured by Medication Events Monitoring System (MEMS) technology) with a control group on DOT. METHODS: We plan to enrol 164 newly diagnosed MDR-TB patients aged ≥ 8 years from three regional hospitals based in rural and urban Uganda. Patients with conditions that affect their dexterity and ability to operate the MEMS-operated medicine equipment will not be eligible to participate in the trial. Patients are randomized to either of the two study arms: self-administered therapy with adherence being monitored using MEMS technology (intervention arm) or health facility-based DOT (control arm) and will be followed up monthly. Adherence is measured by the number of days the medicine bottle is open to access medication as recorded by the MEMS software in the intervention arm and treatment complaint days as recorded in the TB treatment card in the control arm. The primary outcome is the comparison of adherence rates between the two study arms. DISCUSSION: The evaluation of self-administered therapy for patients with MDR-TB is important to inform cost-effective management strategies for these patients. The approval of all oral regimens for the treatment of MDR-TB provides an opportunity for innovations such as MEMS technology to support sustainable options for MDR-TB treatment adherence support in low-resource settings.

Re-engagement in HIV care following a missed visit in rural Uganda

Abstract Objective We conducted a retrospective cohort study to assess the effect of tracking People Living with HIV (PLHIV) after missed clinic visits and factors associated with return to care in rural Uganda. We assessed retention in care among 650 HIV-infected women and men. We used univariable and multivariable generalized linear models to assess demographic and self-reported factors associated with re-engagement in HIV care. Results Of 381 PLHIV who ever missed a scheduled appointment, 68% were female and most (80%) had initiated ART. Most (70%) of those tracked returned to care. Relative to men, women (adjusted risk ratio [ARR] 1.23; 95% confidence interval (CI) 1.05–1.43; p = 0.009) were more likely to return to care after active tracking. PLHIV who missed scheduled visits for other reasons (forgetting, adequate drug supplies, or long distance to clinic) had reduced odds of return to care (ARR 0.41; 95% CI 0.28–0.59; p < 0.001). These data support close monitoring of patient retention in HIV care and active measures to re-engage those who miss an appointment. Furthermore, they highlight the need for targeted interventions to those more resistant to re-engagement such as men

This doctoral research was funded by the Academy at Infectious Diseases Institute through a scholarship awarded to Agnes Bwanika Naggirinya.Abstract Background New interventions aimed at increasing access to and adherence to antiretroviral therapy among young people living with the human immunodeficiency virus (YPLHIV) are needed. This study assessed the cost-effectiveness of the call-for-life interaction voice response tool compared to that of the standard of care (SOC) for promoting treatment adherence and retention in care among YPLHIV in Western Uganda. This cost-effectiveness study used data from a randomized controlled trial and a decision-analytic Markov model to estimate the long-term outcomes and costs of the Call for Life-Interactive Voice Response (CFL-IVR) tool and the usual care from the Ugandan public payer perspective. The model was parameterized using primary data and the literature and adopted a 1-year Markov cycle. The main outcomes were mean annual costs, disability-adjusted life-years (DALYs), and the incremental cost-effectiveness ratio (ICER) in form of cost per DALY averted. The CLF-IVR was deemed cost-effective if the ICER was between 1% and 51% of Uganda’s gross domestic product. We conducted deterministic and probabilistic sensitivity analyses to assess the effect of adjusting parameter values on cost-effectiveness estimates. All costs were reported in 2021 US dollars, and a discount rate of 3% was applied to both costs and outcomes. Results The base case analysis showed that, from the Ugandan public payer perspective, the CLF-IVR led to more mean annual costs ($359 vs.$280) and averted more mean annual DALYs (15.78 vs. 11.09) than the SOC, leading to an ICER of $17 per DALY averted. The base-case results did not change significantly in the deterministic and probabilistic sensitivity analyses. The cost-effectiveness estimates were more responsive to uncertainties surrounding ART duration, viral load suppression rates, and discount rates. Conclusion The CLF-IVR may be a cost-effective intervention for promoting treatment adherence and retention in care among YPLHIV in Uganda and other low-income settings. Once implemented, similar interventions may lead to greater returns in encouraging adherence to ART and retention in care among YPLHIV and other vulnerable groups, and eventually favorable clinical outcomes.
