Uptake of HIV voluntary counseling and testing and associated factors among students in the Higher Institutions of Learning in Kigali, Rwanda: A cross-sectional study

Background HIV/AIDS remains a significant global public health challenge with youth bearing the brunt of the burden. One essential method for preventing and accessing AIDS care is through Voluntary Counselling and Testing (VCT). Regardless of this, youth population continues to have low utilization of VCT services. Objective To assess the uptake of HIV VCT services and associated factors among university students in Kigali. Methods A cross-sectional study among 374 students recruited using stratified sampling was conducted. A structured questionnaire was used to gather information. A multivariable logistic regression analysis was used to assess the independent factors associated with VCT uptake. Results The prevalence of VCT uptake was 59.9%. The logistic regression revealed that being Catholic (AOR = 11.99, 95%CI: 5.44-26.41) and Moslem (AOR = 37.34, 95%CI: 2.67-128.36) compared to Protestant, as well as availability of VCT services (AOR = 5.15, 95%CI: 3.11 - 8.541) favored the use VCT. On the other hand, being aged 20 to 24 years (AOR = 0.112, 95%CI: 0.04 - 0.29) had low likelihood of using VCT than those more than 24 years of age. Conclusion VCT uptake was significantly positively associated with religion and VCT services availability, and negatively associated with age 20-24 years in the campus. Therefore, targeted actions of disseminating information on benefits of VCT and enhancing accessibility of VCT services among students are necessary for the increased VCT uptake to be attained.

Facteurs associés à la non-observance des personnes vivant avec le VIH à la thérapie antirétrovirale / Factors associated with non-adherence to antiretroviral therapy among people living with HIV

Le VIH est un fléau le plus meurtrier de l'histoire et les antirétroviraux demeurent une panacée. Cette étude cherche à identifier les facteurs associés à l'inobservance des personnes vivant avec le VIH (PVVIH) à la thérapie antirétrovirale (TARV). Méthodes L'étude transversale analytique a été menée au sein de la structure ActionsCommunautaires SIDA/ Avenir Meilleur pour les Orphelins. Elle a ciblé les PVVIH éligibles. L'échantillonnage non probabiliste du type occasionnel a été utilisé par la technique d'interview. Les analyses bivariée et multivariée ont été utilisées ainsi que la régression logistique par le logiciel SPSS version 16.0. Résultats 72 PVVIH ont été interviewées dont l'âge moyen était de 44 ans, avec un sex ratio de 2 femmes pour 1 homme. L'observance thérapeutique était de 55,6 %. Les facteurs associés à l'inobservance sont l'anxiété (51,4%), le stress, la mauvaise relation avec le soignant (44,4%), l'oubli (37,5%), la démotivation sexuelle (20,8%), la conscience personnelle (19,4%) et le manque de confidentialité (13,9%). Conclusion L'inobservance à la thérapie antirétrovirale constitue une problématique dans le contexte de la RDC. Il est important d'insister sur l'éducation thérapeutique dans le succès de la thérapie antirétrovirale

Adolescents infectés par le VIH au cours de la transition des soins pédiatriques aux soins pour adultes dans un hôpital de référence à Abidjan (Côte d'Ivoire). Etudes des caractéristiques cliniques / Hiv-infected adolescents during the transition from paediatric to adult care in a referral hospital in abidjan (cote d'ivoire). Clinical characteristics study

Les adolescents vivant avec le VIH ont de moins bons résultats que les adultes en matière de soins, en particulier lors de la transition entre les soins pédiatriques et les soins aux adultes. L' Objectif était de décrire les particularités socio familiales, cliniques, para cliniques et thérapeutiques des adolescents au cours de cette phase charnière de leur prise en charge. Méthodes. Il s'agissait d'une étude rétrospective à visée descriptive qui s'est déroulé du 1er au 31 mars 2020 (1 mois) sur la cohorte d'enfants vivant avec le VIH suivi au CHU de Cocody (Abidjan) de novembre 2005 à mars 2020 (15 ans). Résultats. Trente-huit adolescents en phase de transition ont été inclus. L'âge moyen était de 17 ans avec des extrêmes de 15 et 20 ans. Le sex ratio était de 1,37. La majorité des enfants étaient scolarisé (81,57%) avec un retard scolaire chez plus de la moitié (58%). Près de la moitié des cas était orphelin d'un ou des 2 parents (47,4%). Les conditions socioéconomiques étaient modestes ou défavorable (73,7%). Près de la moitié des adolescents était suivi depuis plus de 10 ans (42%). Un surpoids a été retrouvé dans 21% des cas. On notait un échec immunologique dans 10,5% des cas et un échec virologique dans un tiers des cas (31,6%). L'observance était moyenne ou mauvaise chez près de la moitié des adolescents (44,7%). La majorité des adolescents (94,7%) n'avait jamais eu de contact avec un médecin d'adulte. Conclusion. La transition des soins pédiatriques aux soins pour adulte est un processus au cours duquel l'adolescent est confronté à des diffi cultés socio familiale et scolaire, a l'inobservance avec échec thérapeutique qui doit être repéré de façon précoce. Le succès de cette étape nécessite également le rapprochement entre pédiatres et médecins d'adultes pour une prise en charge optimal des patients.

Testers' compliance to the quality standards of HIV rapid testing services in Primary Health Care Facilities in Makete District, Tanzania

Background: HIV rapid testing services is one among key interventions in the controlling of HIV/AIDS. Despite availability of quality standards, the quality of HIV rapid testing services remains questionable since non-laboratory testers are allowed to conduct testing while they are not specialized in providing testing services. Objective: To evaluate the compliance to the quality standards of HIV rapid testing services provided by non-laboratory testers in Makete District, Tanzania Methods: An explanatory descriptive study employing quantitative approach of data collection was used. An observation of 23 non-laboratory testers performing HIV rapid tests, observation of HIV testing points and documents review was done in 23 testing points to collect data. Data were analyzed using a programmed excel sheet and a three-point scale was used to determine the level of compliance to quality standards. Results: Analysis shows that out of 23 testing points visited, the level of compliance to quality standards was lower for 22 (95.6%) testing points and moderate in 1 (4.4%) testing point. None of the testing point was highly complied to quality standards for HIV rapid testing services. Conclusion: The quality of HIV rapid testing services provided by non-laboratory testers is below the established quality standards for HIV rapid testing services.

Twenty years of prevention of mother to child HIV transmission: research to implementation at a national referral hospital in Uganda

Background: Over 90% of new paediatric HIV infections are acquired through mother to child transmission. Prevention of mother to child HIV transmission (PMTCT) research in sub-Saharan Africa informed WHO guidelines which enabled implementation of PMTCT programs globally. Objectives: To describe Makerere University-Johns Hopkins University (MU-JHU) perinatal HIV prevention research and implementation of the Mulago National Referral Hospital (MNRH) PMTCT program. Methods: Perinatal HIV prevention studies conducted at MU-JHU between 1997­2016 were summarized. Program aggregated data was extracted and analyzed using STATA 15. Results: In 1999, the HIVNET 012 study demonstrated that single-dose nevirapine (sdNVP) to the mother at onset of labor and to her newborn, reduced MTCT by nearly 50%. In 2016, the PROMISE study documented the safety and efficacy of ART during pregnancy and breastfeeding period. Program implementation at MNRH started in 2000. Uptake of HIV testing increased from 70% to 99% from 2006 onwards. sd NVP was the initial ARV regimen but by 2012, MOH recommended Option B+(triple therapy). MTCT rates reduced from 16.9% in 2001 to 2.3% in 2020. Conclusion: Perinatal HIV prevention clinical trials conducted at MU-JHU provided evidence to inform WHO PMTCT guidelines. MNRH program evaluation demonstrated the significant decline in MTCT rates over the last two decades.

Indirect serum biomarkers perform sub optimally in screening for significant liver fibrosis among HIV-infected and uninfected adults in Uganda

ntroduction: Indirect serum biomarkers present an acceptable noninvasive and cheap alternative for screening of significant liver fibrosis (SLF). Evaluation of their use in resource limited settings is important to determine their utility. Methods: We conducted a cross sectional study among 520 HIV infected and HIV uninfected adults attending care clinics in Kampala Uganda. Presence of SLF was determined using Fibroscan® liver stiffness measurement of ≥7.2KPa. The diagnostic value of indirect serum biomarkers for diagnosis of SLF was evaluated using the area under the receiver operating characteristics curve (AUROC) using Fibroscan® as gold standard. Results: Overall AUROC values for Age Platelet Index (API), Aspartate to Alanine Ratio (AAR), AST-to-Platelet Ratio Index (APRI), Fibrosis Index based on 4 Factors (FIB-4) and Gamma glutamyl transferase to Platelet Ratio Index (GPR) were 0.52, 0.49, 0.55, 0.55 and 0.54 respectively. Among HIV-infected participants AUROC values were slightly improved at predicting presence of SLF but still under 70%. Conclusion: Despite APRI and FIB-4 being more likely to identify participants with SLF, the overall diagnostic value of all serum biomarkers was poor with and without stratification by HIV status. We recommend the use of Fibroscan® technology as more accurate non-invasive diagnostic method for screening of SLF

COVID-19 and HIV viral load suppression in children andadolescents in Durban, South Africa

Background: The coronavirus disease 2019 (COVID-19) pandemic poses challenges to paediatric and adolescent HIV treatment programme. Modelling exercises raised concerns over potential impact of disruptions. Objectives: To describe the impact of the COVID-19 pandemic on viral load (VL) testing among infants, children and adolescents on antiretroviral treatment (ART) in Durban, South Africa. Method: Routinely collected, aggregated data of monthly VL counts done on all those less than 19 years old from January 2018 to January 2022 was analysed. An interrupted time series analysis using a Prais-Winsten linear regression model, including terms for lockdowns and excess mortality determined VL trends. Results: The unadjusted mean VL was 2166 (confidence interval [CI]: 252.2) and 2016 (CI: 241.9), P = 0.039, and percentage VL suppression rates (72.9%, CI: 2.4% vs 73.6%, CI: 1.8%) across COVID and pre-COVID periods, showing no significant difference, P = 0.262. In the interrupted time series analysis, modelled monthly VL counts did not differ significantly by lockdown level (e.g., level 5 lockdown: ­210.5 VLs, 95% CI: ­483.0 to +62.1, P = 0.138) or excess mortality (­0.1, 95% CI: ­6.3 to 6.1, P = 0.969). A significant downward trend in VL testing over time, including during the pre-COVID-19 period (­6.6 VL per month, 95% CI: ­10.4 to ­2.7, P = 0.002), was identified. Conclusion: Viral load suppression for children and adolescents were not negatively affected by COVID-19. A trend of decrease in VL testing predated COVID-19. What this study adds: Evidence presented that HIV VL testing and suppression rates in children and adolescents in a high burden setting were sustained through the COVID pandemic.

Contexte et objectif. L'éviction des infections sexuellement transmissibles et du VIH (IST/VIH) chez les jeunes et adolescents passe par l'adoption de comportement sexuel sain. L'objectif était de décrire les comportements sexuels à risque d'IST/VIH chez les élèves du secondaire du CEG1 de Natitingou en 2020. Méthodes. Il s'est agi d'une étude transversale à visée analytique qui s'était déroulée au CEG1 de Natitingou. Ont été inclus dans l'étude, les élèves régulièrement inscrit au CEG1 de Natitingou. Résultats. Les élèves du CEG1 de Natitingou avaient des comportements sexuels à risque dans 28,71%. Ils fréquentaient les professionnelles de sexe dans 5,9 % et le préservatif était utilisé occasionnellement (55 %). Les élèves filles (17 %) avaient des rapports sexuels, en compensation de l'argent. La partouze a été pratiquée dans 9,9 % des cas. Le sexe masculin (p= 0,011), l'âge (p< 0,0001), l'auto prise en charge des frais d'étude (p= 0,037) et la méconnaissance des élèves sur les IST/SIDA (p= 0,041) étaient associés de manière indépendante à l'adoption d'un comportement sexuel à risque. Conclusion. Les adolescents du CEG1 de Natitingou ont des comportements sexuels à risque d'IST/VIH. L'école, l'environnement religieux et les parents doivent s'unir pour amener les jeunes à réduire les comportements à risque

The global HIV response at 40

It is helpful to divide the global HIV response into three phases: The first, from about 1980 to 2000, represents "Calamity". The second, from roughly 2000 to 2015 represents "Hope." The third, from 2015, is unfolding and may be termed "Choices" ­ and these choices may be severely constrained by COVID, so "Constrained Choices in an era of COVID" may prove more apt. As we take stock of HIV at 40, there are positive lessons for the wider health response ­ and challenging reflections for the wider impact of the global HIV response. The positive lessons include: (1) the importance of activism; (2) the role of scientific progress and innovation; (3) the impact of evidence in concentrating resources on proven approaches; (4) the importance of surveillance to understanding transmission dynamics; (5) the use of epidemic intelligence to guide precision implementation; (6) the focus on implementation cascades (diagnosis, linkage, adherence, disease suppression); and finally (7) an overarching execution and results focus. Given this remarkable legacy, it seems churlish to ask whether the HIV response could have achieved more. yet, consider these approximate figures. Development assistance for HIV totals about 100 billion dollars, 70 billion from the USA matched by roughly 100 billion in domestic resources. For 200 billion dollars, should we not have achieved more than 23 million people initiating treatment (very crudely, 10 000 dollars per person on treatment)? Much of the hundred billion dollars of development assistance (roughly half) focused on about a dozen priority countries in eastern and southern African. The larger PEPFAR recipients, with populations of roughly 50 million, each received 5 billion dollars or more cumulatively. And there are further Global Fund contributions of an additional billion dollars in many of these countries. For 6 billion dollars per country, should we have expected more? The World Bank Human Capital Project posits that to maximize human capital formation, countries must ensure that their children survive, are well nourished and stimulated, learn skills and live long, productive lives. Using the Human Capital Index (a composite index based on these factors), South Africa ­ the largest HIV financing recipient ­ ranks 126th of 157 countries, below Haiti, Ghana, the Congo Republic, Senegal and Benin. Consider how many recipients of major HIV development finance fall into the bottom fifth: Namibia, Botswana, Eswatini (formerly Swaziland), Malawi, South Africa, Tanzania, Zambia, Uganda, Lesotho, Ethiopia, Mozambique, Cote D'Ivoire and Nigeria. Of course, causality is unresolved and there are several possible explanations: (1) low human capital formation may increase HIV transmission; (2) the HIV epidemic may have intergenerational impacts; (3) the all-consuming focus on HIV may have displaced other health, education and development priorities. yet, it remains hard to see these data and to argue that successful HIV responses among the largest HIV financing recipients strengthened their wider health sector and human development outcomes. A plausible principle emerges. Narrowly targeted disease-specific emergency responses may lead to disease-specific gains but do not improve governance or national systems capacity or wider disease or development outcomes. This is not to undermine the emergency origins of the HIV response; 2021 is not 2000 and it is unlikely that we would have 23 million people initiating treatment without an emergency response. yet, there are reasons (intensified by COVID), to suggest that we must pivot towards long-term, integrated, developmental, nationally owned and financed, systems-orientated responses ­ particularly when both development assistance and national budgets are likely to be constrained in an era of COVID.

Problématique duDiagnostic du VIH en Afrique Subsaharienne: Résultats Erronés dans une Etude Pilote (NAMSAL) au Cameroun

Introduction.The NAMSAL therapeutic trial evaluated the non-inferiority of a first line treatment comprising Dolutegravir to another line comprising Efavirenz 400. The criteria for not taking part to the trial included infection with non-M HIV-1, untreated patients with HIV viral load <1000 copies/mL. The objective of this study was to explain why some treatment naïve patients had undetectable viral loads. Materials and methods. Out of 817 patients pre-included with HIV-1 infection and untreated, 204 were not included and the present study focused on 114 of these 204 patients not included in NAMSAL. HIV plasma viral load, serological status and the serotype were confirmed by RT-qPCR (Abbott), INNOLIA HIVI/II Score (Fujirebio), and by ELISA with synthetic peptides of thedifferent HIV-1&2 groups. Universal or specific PCR (M and O) were performed on the samples for molecular confirmation and characterization. Results. Amongthe 114 patients studied, 49 (43%) had a viral load < 1000 copies/mL and 65 (57%) had a viral load > 1000 copies/mL. When reported to the whole cohort of pre-included patients (n=817), 4/817 (0.5%) were group-O confirmed by molecular biology. Based on the PCR results, 14 out of 817 patients (1.7%) deemed to be HIV-1 positive were most likely uninfected. Conclusion. 1.7% of HIV-1 patients referred for inclusion in NAMSAL were not actually infected. Ongoing staff training and quality control of laboratories must be strengthened in Cameroon in view of the social and economic consequences of misdiagnosis.

Quality of HIV laboratory testing in Tanzania: a situation analysis

Tanzania is scaling up prevention; treatment; care and support of individuals affected with HIV. There is therefore a need for high quality and reliable HIV infection testing and AIDS staging. The objective of this study was to assess laboratories capacities of services in terms of HIV testing and quality control. A baseline survey was conducted from December 2004 to February 2005 in 12 laboratories which were conveniently selected to represent all the zones of Tanzania. The questionnaires comprised of questions on laboratory particulars; internal and external quality control for HIV testing and quality control of reagents. Source and level of customer satisfaction of HIV test kits supply was established. Of 12 laboratories; nine used rapid tests for screening and two used rapid tests for diagnosis. In the 12 laboratories; four used double ELISA and five used single ELISA and three did not use ELISA. Confirmatory tests observed were Western Blot in three laboratories; DNA PCR in two laboratories; CD4 counting in seven laboratories; and viral load in two laboratories. Although all laboratories conducted quality control (QC) of the HIV kits; only two laboratories had Standard Operating Procedures (SOPs). Internal and external quality control (EQC) was done at varied proportions with the highest frequency of 55.6(5/9) for tnternal quality control (IQC) for rapid tests and EQC for ELISA; and the lowest frequency of 14.3(1/ 7) for IQC for CD4 counting. None of the nine laboratories which conducted QC for reagents used for rapid tests and none of the five which performed IQC and EQC had SOPs. HIV kits were mainly procured by the Medical Store Department and most of laboratories were not satisfied with the delay in procurement procedures. Most of the laboratories used rapid tests only; while some used both rapid tests and ELISA method for HIV testing. In conclusion; the survey revealed inadequacy in Good Laboratory Practice and poor laboratory quality control process for HIV testing reagents; internal and external quality control
