BACKGROUND: The WHO recommends TB symptom screening and TB preventive therapy (TPT) for latent TB infection (LTBI) in persons living with HIV (PLWH). However, TPT uptake remains limited. We aimed to characterize and contextualize gaps in the TPT care cascade among persons enrolling for antiretroviral therapy (ART).SETTING: Four PEPFAR‐supported facilities in Uganda.METHODS: We studied a proportionate stratified random sample of persons registering for ART when TPT was available. Patient‐level data on eligibility, initiation, and completion were obtained from registers to determine proportion of eligible patients completing each cascade step. We interviewed providers and administrators and used content analysis to identify barriers to guideline‐concordant TPT practices.RESULTS: Of 399 study persons, 309 (77%) were women. Median age was 29 (IQR 25–34), CD4 count 405 cells/µL (IQR 222–573), and body mass 23 kg/m2 (IQR 21–25). Of 390 (98%) screened, 372 (93%) were TPT‐eligible. Only 62 (17%) eligible PLWH initiated and 36 (58%) of 62 completed TPT. Providers reported hesitating to prescribe TPT because they lacked confidence excluding TB by symptom screening alone and feared promoting drug resistance. Although isoniazid was available, past experience of irregular supply discouraged TPT initiation. Providers pointed to insufficient TB‐dedicated staff, speculated that patients discounted TB risk, and worried TPT pill burden and side effects depressed ART adherence.CONCLUSIONS: While screening was nearly universal, most eligible PLWH did not initiate TPT. Only about half of those who initiated completed treatment. Providers feared promoting drug resistance, harbored uncertainty about continued availability, and worried TPT could antagonize ART adherence. Our findings suggest urgent need for stakeholder engagement in TPT provision.

Background High prevalence of HIV and hypertension in sub-Saharan Africa puts adults living with HIV (ALWH) at high risk of end-organ complications. Both World Health Organization (WHO) and national guidelines recommend screening and treatment of hypertension among ALWH on antiretroviral therapy (ART). We evaluated the implementation of hypertension screening among adults on ART at three Uganda Cares Primary care facilities. Methods Using a sequential explanatory mixed-methods approach, we reviewed patient records, and interviewed both patients and providers during 2018 and 2019. We obtained demographics, clinical and blood pressure (BP) measurements via records review. We estimate the period prevalence of screening and use adjusted modified Poisson regression models to evaluate predictors of screening. In-depth interviews were analysed using a thematic approach to explain the observed prevalence and predictors of BP screening. Results Records for 1426 ALWH were reviewed. Patients had a median age of 35 years and 65% of them were female. Most were on ART (89% on first-line) with a median duration of 4 years. Only 262 (18%) were overweight or obese with a body mass index (BMI) > 25 Kg/M2. In 2017 or 2018 patients made a median of 3 visits and 783 patients had a BP recorded, hence a period prevalence 55%. Older age, male sex, more clinic visits, and clinic site were associated with screening in the adjusted analyses. Erratic BP screening was corroborated by patients’ and providers’ interviews. Challenges included; high patient numbers, low staffing, provider apathy, no access to treatment, and lack of functioning of BP equipment. Conclusion Almost half of regular HIV clinic attendees at these prototypical primary care HIV clinics were not screened for hypertension for a whole year. Improving BP screening requires attention to address modifiable challenges and ensure local buy-in beyond just providing equipment.

Introduction Loss-to-follow-up among women living with HIV (WLWHIV) may lead to unfavorable outcomes for both mother and exposed infant. This study traced WLWHIV disengaged from care and their infants and compared their outcomes with those retained in care. Methods The study included WLWHIV who initiated ART during pregnancy at six public clinics in Uganda. A woman was defined as disengaged (DW) if she had not attended her 6-week post-partum visit by 10 weeks after her estimated date of delivery. DW were matched with retained women (RW) by age and duration on ART. Nurse counselors traced all selected DW via telephone and community visits to assess vital status, infant HIV sero-status and maternal HIV viral load through blood draws. Results Between July 2017 and July 2018, 734 women (359 DW and 375 RW) were identified for the study. Tracing was attempted on 349 DW and 160 (44.6%) were successfully located and enrolled in the study. They were matched with 162 RW. Among DW, 52 (32.5%) transferred to another health facility. Very few DW, 39.0% were HIV virally suppressed (<1000 copies/ml) compared to RW 89.5%, P<0.001). Among 138 babies born to DW, 4.3% tested positive for HIV compared to 1.4% among babies born to RW (P = 0.163). Conclusion Pregnant and breastfeeding WLWHIV who disengage from care are difficult to find in urban environments. Many have detectable viral loads, leading to the potential for an increased risk of MTCT. Efforts to reduce disengagement from care are critical for the successful elimination of MTCT in resource-limited settings.
