Background Nurses form a very important part of the health workforce in sub-Saharan Africa. Research nurses are critical to the implementation of clinical trials. The duties and responsibilities of a research nurse are complex and continue to evolve as new practices and guidelines are formulated. Aims In this paper, we have highlighted the major contributions of research nurses in HIV clinical trials in sub-Saharan Africa from the unique perspective of Ugandan nurses. Methods The requirements and challenges of two multi-site, randomised cryptococcal meningitis clinical trials in Uganda were assessed from the perspective of research nurses conducting complex research in resource-limited settings. Results Over the course of 8 years, approximately 1739 participants were screened and 934 people were enrolled into the two trials. The nurses found that patient education and engagement were among the most important predictors of success in minimising loss to follow-up. Conclusions Research nurses played a key role in communicating clinical research goals to patients, obtaining informed consent, minimising loss to follow-up, and ensuring that research practices are translated and implemented into standard of care. However, there remains a need to integrate the same level of care provided in clinical research studies to non-study patients.

PurposeThe objectives of the International epidemiology databases to evaluate AIDS (IeDEA) are to (i) evaluate the delivery of combination antiretroviral therapy (ART) in children, adolescents and adults in sub-Saharan Africa, (ii) to describe ART regimen effectiveness, durability and tolerability, (iii) to examine HIV-related comorbidities and coinfections and (iv) to examine the pregnancy-related and HIV-related outcomes of women on ART and their infants exposed to HIV or ART in utero or via breast milk.ParticipantsIeDEA is organised in four regions (Central, East, Southern and West Africa), with 240 treatment and care sites, six data centres at African, European and US universities, and almost 1.4 million children, adolescents and adult people living with HIV (PLWHIV) enrolled.Findings to dateThe data include socio-demographic characteristics, clinical outcomes, opportunistic events, treatment regimens, clinic visits and laboratory measurements. They have been used to analyse outcomes in PLWHIV-1 or PLWHIV-2 who initiate ART, including determinants of mortality, of switching to second-line and third-line ART, drug resistance, loss to follow-up and the immunological and virological response to different ART regimens. Programme-level estimates of mortality have been corrected for loss to follow-up. We examined the impact of coinfection with hepatitis B and C, and the epidemiology of different cancers and of (multidrug resistant) tuberculosis, renal disease and of mental illness. The adoption of ‘Treat All’, making ART available to all PLWHIV regardless of CD4+ cell count or clinical stage was another important research topic.Future plansIeDEA has formulated several research priorities for the ‘Treat All’ era in sub-Saharan Africa. It recently obtained funding to set up sentinel sites where additional data are prospectively collected on cardiometabolic risks factors as well as mental health and liver diseases, and is planning to create a drug resistance database.

Abstract Background Adherence in the treatment of latent tuberculosis infection (LTBI) is closely related to reactivation and infection control in the population. However, there has been little research on which populations are at higher risk of loss to follow-up. The aim of this study is to investigate how the adherence of LTBI patients in the United States (US) differs by region of origin. Methods A retrospective, observational study was conducted from 2001 to 2020. LTBI patients were identified from the Cuyahoga County Tuberculosis Clinic in Cleveland, Ohio. Only patients who were informed of the diagnosis of LTBI were included. Patients were discharged from the Tuberculosis outpatient clinic upon completion of treatment or when the physician decided to discontinue treatment. We defined loss to follow-up as a case where LTBI was diagnosed but the patient was not formally discharged. Patients whose treatment was interrupted due to side effects were not considered loss to follow-up. Odds ratios were calculated using a multivariable regression model with patients from North America as the reference group. Results Of 4018 LTBI patients, 1171 (28.7%) were lost to follow-up, of which 950/2314 (41.0%) were from North America. Compared with LTBI patients from North America, significantly lower loss to follow-up rates were observed for those from Middle East and North Africa 30/170 (17.7% OR 0.52, 95% Confidence Interval (CI) 0.31-0.89), South Asia 60/692 (8.7% OR 0.41, 95% CI 0.21-0.78), and Sub-Saharan Africa 69/526 (13.1% OR 0.22, 95% CI 0.14-0.36). Conclusion The analysis showed that a high loss to follow-up rate was observed in the patient groups from North America, Europe and Central Asia, and Latin America & the Caribbean. LTBI patients from North America had a significantly higher loss to follow-up rate than those from Middle East and North Africa, South Asia, and Sub-Saharan Africa, respectively. Further research is needed to determine how to intervene in the poorly adherent patient population, such as LTBI patients from North America, Europe and Central Asia, and Latin America & the Caribbean.
