These data demonstrate the effectiveness of ART in a low-resource setting. Children and patients of all ages taking the d4T/3TC/NVP regimen were more likely to have viral failure. Our data suggest that viral failure occurring 6 months or more after the start of ART regimens commonly used in Uganda is likely to be associated with NNRTI- and 3TC-resistant virus.

BackgroundThe increased immune activation and inflammation of chronic HIV-infection and the characteristic dyslipidemias associated with HIV infection and antiretroviral therapy (ART) contribute to an increased risk of atherosclerotic vascular disease among HIV-infected adults. There is an emerging need to understand determinants of cardiovascular disease (CVD) among individuals aging with HIV in sub-Saharan Africa. We determined the prevalence of subclinical atherosclerosis [carotid intima media thickness (CIMT) ≥0.78 mm] and its correlation with traditional CVD risk factors among HIV-infected adults.MethodsIn a cross-sectional study, HIV-infected adults (ART-naïve and ART-treated) were consecutively selected from patients' enrollment registers at two large HIV clinics at Mulago Hospital, Kampala, Uganda. We measured traditional CVD risk factors including age, biophysical profile, fasting blood sugar and serum lipid profile as well as biomarkers of inflammation. High resolution ultrasound was used to measure common carotid CIMT.ResultsOf 245 patients, Median age [Interquartile range (IQR)] 37 years (31–43), 168 (69%) were females; and 100 (41%) were ART-treated for at least 7 years. Overall, 34/186 (18%) had subclinical atherosclerosis; of whom 15/108 (14%) were ART-naïve whereas 19/78 (24%) were ART-treated. Independent predictors of subclinical atherosclerosis included age [odds ratio (OR) 1.83 per 5-year increase in age; 95% confidence interval (CI) 1.24–2.69; p = 0.002], body mass index (BMI); OR 1.15; CI 1.01–1.31; p = 0.041 and high low density lipoprotein (LDL) [OR 2.99; CI 1.02–8.78, p = 0.046]. High sensitivity C-reactive protein (hsCRP) was positively correlated with traditional cardio-metabolic risk factors including waist circumference (r = 0.127, p = 0.05), triglycerides (r = 0.19, p = 0.003) and Total Cholesterol: High Density Lipoprotein ratio (TC:LDL) (r = 0.225, p<0.001).ConclusionThe prevalence of subclinical atherosclerosis was 18% among HIV-infected adults in Uganda. Traditional CVD risk factors were associated with subclinical atherosclerosis. We recommend routine assessment of traditional CVD risk factors within HIV care and treatment programs in sub-Saharan Africa.

Background With funding from the United States Health Resources Service Administration (HRSA), a consortium of health professional training institutions from Africa developed HIV-specific, interprofessional, team-based educational resources to better support trainees during the transition period between pre-service training and professional practice. Methods Ten faculty members representing nine medical and nursing schools in sub-Saharan Africa (SSA) developed a training package of modules focused on core clinical, public health, interprofessional education (IPE), and quality improvement (QI) domains related to HIV service delivery. Curriculum development was informed by a rapid needs assessment of existing tools and future needs for HIV education across 27 SSA health professions training institutions. A total of 17 modules were developed, targeted at newly qualified health care professionals to be taught in a series of two-day workshops meant to complement existing institution specific HIV-curricula. Results Between April and July 2019, a comprehensive case-based HIV training package was developed to support trainees in transition from pre-service training to independent professional practice. Each module, addressing different elements of interprofessional practice, was intended to be delivered in an interprofessional format. Thus far, 70 health professions training institutions in 14 countries have implemented the program; 547 educators facilitated STRIPE workshops, with a total of 5027 learners trained between September 2019 and September 2020. Conclusions To our knowledge this is the first IPE HIV-specific curriculum explicitly focused on enhancing the quality of training provided to graduating health care professionals working in SSA. The collaborative, cross-institutional, interprofessional approach to curriculum development provides a benchmark for how best-practice approaches to education can be disseminated in SSA.

ObjectiveTo assess the impact of an interprofessional case-based training programme to enhance clinical knowledge and confidence among clinicians working in high HIV-burden settings in sub-Saharan Africa (SSA).SettingHealth professions training institutions and their affiliated clinical training sites in 12 high HIV-burden countries in SSA.ParticipantsCohort comprising preservice and in-service learners, from diverse health professions, engaged in HIV service delivery.InterventionA standardised, interprofessional, case-based curriculum designed to enhance HIV clinical competency, implemented between October 2019 and April 2020.Main outcome measuresThe primary outcomes measured were knowledge and clinical confidence related to topics addressed in the curriculum. These outcomes were assessed using a standardised online assessment, completed before and after course completion. A secondary outcome was knowledge retention at least 6 months postintervention, measured using the same standardised assessment, 6 months after training completion. We also sought to determine what lessons could be learnt from this training programme to inform interprofessional training in other contexts.ResultsData from 3027 learners were collected: together nurses (n=1145, 37.9%) and physicians (n=902, 29.8%) constituted the majority of participants; 58.1% were preservice learners (n=1755) and 24.1% (n=727) had graduated from training within the prior year. Knowledge scores were significantly higher, postparticipation compared with preparticipation, across all content domains, regardless of training level and cadre (all p<0.05). Among 188 learners (6.2%) who retook the test at >6 months, knowledge and self-reported confidence scores were greater compared with precourse scores (all p<0.05).ConclusionTo our knowledge, this is the largest interprofessional, multicountry training programme established to improve HIV knowledge and clinical confidence among healthcare professional workers in SSA. The findings are notable given the size and geographical reach and demonstration of sustained confidence and knowledge retention post course completion. The findings highlight the utility of interprofessional approaches to enhance clinical training in SSA.

BackgroundDental caries is a multifactorial disease that affects many people. Even though microorganisms play a crucial role in causing dental caries, diagnosis is routinely macroscopic. In order to improve early detection especially in HIV patients who are disproportionately affected, there is need to reconcile the macroscopic and microscopic characteristics of dental caries. Therefore, the aim of this study was to characterize the oral microbiota profile along the decayed, missing, filled teeth (DMFT) index using amplicon sequencing data.MethodsAmplicon sequencing of the V6-V8 region of the 16S rRNA gene was done on DNA recovered from whole unstimulated saliva of 59 HIV positive and 29 HIV negative individuals. The microbial structure, composition and co-occurrence networks were characterized using QIIME-2, Phyloseq, Microbiome-1.9.2 and Metacoder in R.ResultsWe characterized the oral microbiota into 2,093 operational taxonomic units (OTUs), 21 phyla and 239 genera from 2.6 million high quality sequence reads. While oral microbiota did not cluster participants into distinct groups that track with the DMFT index, we observed the following: (a) The proportion of accessory microbiota was highest in the high DMFT category while the core size (∼50% of richness) remained relatively stable across all categories. (b) The abundance of core genera such as Stomatobaculum, Peptostreptococcus and Campylobacter was high at onset of dental caries, (c) A general difference in oral microbial biomass. (d) The onset of dental caries (low DMFT) was associated with significantly lower oral microbial entropy.ConclusionsAlthough oral microbial shifts along the DMFT index were not distinct, we demonstrated the potential utility of microbiota dynamics to characterize oral disease. Therefore, we propose a microbial framework using the DMFT index to better understand dental caries among HIV positive people in resource limited settings.
