Abstract
Introduction: HIV2 is endemic in West Africa. In Burkina Faso, its prevalence was estimated at 2%. The aim of this work was to evaluate the follow-up of patients and also to contribute to the availability of data. Methods: We involved 18 years or older. Infection was screened according to the national algorithm. A cross- sectional study from first June 2017 to 31 December 2017 was performed. For each patient, sociodemographic, clinical, biological, therapeutic and evolution data were collected and analyzed. Results: The proportion of patients infected with HIV2 (n = 48; 1.7%) and HIV2 + 1 (n = 67; 2.4%) was 4.3%. The sex rat mean age was 50.3 ± 8.5 years. The combination of 2INTI + LPV/r was the most prescribed (n = 73; 63.5%). The average gain of LTCD4 has evolved from + 236 cells/mm3 in 2011 to + 364 cells/mm3 in 2015. The retention rate at grade 5 was about 70%. Conclusion: The immunological and clinic response of the patients was satisfactory. More than half of the patients remained in the continuum of care after five years of follow-up.

Abstract
INTRODUCTION Undernutrition is considered a marker for poor prognosis among people living with HIV (PLHIV), particularly in sub-Saharan Africa (SSA), where undernutrition and HIV are both highly prevalent. Evidence suggests that undernutrition (body mass index <18.5 kg/m2) is one of the main factors that significantly increases the risk of lost to follow-up (LTFU) in PLHIV. However, primary studies in SSA have reported inconsistent findings on the relationship between undernutrition and LTFU among adults living with HIV. To the best of our knowledge, no systematic review which aimed to summarise the available evidence. Hence, this review aims to determine the pooled effect of undernutrition on LTFU among adults living with HIV in SSA. METHODS AND ANALYSIS PubMed, EMBASE, Web of Science, Scopus, and, for grey literature, Google Scholar will be systematically searched to include relevant articles published since 2005. Studies reporting the effect of undernutrition on LTFU in adults living with HIV in SSA will be included. The Newcastle-Ottawa Scale will be used for quality assessment. Data from eligible studies will be extracted using a standardised data extraction tool. Heterogeneity between included studies will be assessed using Cochrane Q-test and I2 statistics. The Egger's and Begg's tests at a 5% significance level will be used to evaluate publication bias. As heterogeneity is anticipated, the pooled effect size will be estimated using a random-effects model. The final effect size will be reported using the adjusted HR with a 95% CI. ETHICS AND DISSEMINATION Ethical approval is not required for a protocol for a systematic review. The results of this systematic review will be published in a peer-reviewed journal and will be publicly available. PROSPERO REGISTRATION NUMBER CRD42021277741.

Abstract
BACKGROUND Programmatic treatment outcome data for people living with human immunodeficiency virus type 2 (HIV-2) in West Africa, where the virus is most prevalent, are scarce. METHODS Adults with HIV-2 initiating or receiving antiretroviral therapy (ART) through the Senegalese national AIDS program were invited to participate in this prospective, longitudinal observational cohort study. We analyzed HIV-2 viral loads, CD4 cell counts, antiretroviral drug resistance, loss to follow-up, and mortality. We also examined changes in treatment guidelines over time and assessed progress toward the Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 targets for HIV-2. RESULTS We enrolled 291 participants at 2 sites for 926.0 person-years of follow-up over 13 years. Median follow-up time was 2.2 years per participant. There were 21 deaths reported (7.2%), and 117 individuals (40.2%) were lost to follow-up, including 43 (14.7%) who had an initial visit but never returned for follow-up. CD4 counts and HIV-2 viral suppression (< 50 copies/mL) at enrollment increased over calendar time. Over the study period, 76.7% of plasma viral loads for participants receiving ART were suppressed, and median CD4 gain was 84 cells/μL in participants' first 2 years on study. Since the UNAIDS 90-90-90 strategy was published, 88.1% of viral loads were suppressed. Fifteen percent of patients experienced virologic failure with no known resistance mutations, while 56% had evidence of multiclass drug resistance. CONCLUSIONS Participants in the Senegalese national AIDS program are initiating ART earlier in the course of disease, and more modern therapeutic regimens have improved outcomes among those receiving therapy. Despite these achievements, HIV-2 treatment remains suboptimal, and significant challenges to improving care remain.

Effects of undernutrition on mortality and morbidity among adults living with HIV in sub-Saharan Africa: a systematic review and meta-analysis. BMC Infect Dis 2021; 21:1. [PMID: 33390160 PMCID: PMC7780691 DOI: 10.1186/s12879-020-05706-z] [Citation(s) in RCA: 195] [Impact Index Per Article: 65.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Accepted: 12/11/2020] [Indexed: 01/04/2023] Open
Abstract
Background Undernutrition is one of the most common problems among people living with HIV, contributing to premature death and the development of comorbidities within this population. In Sub-Saharan Africa (SSA), the impacts of these often inter-related conditions appear in a series of fragmented and inconclusive studies. Thus, this review examines the pooled effects of undernutrition on mortality and morbidities among adults living with HIV in SSA. Methods A systematic literature search was conducted from PubMed, EMBASE, CINAHL, and Scopus databases. All observational studies reporting the effects of undernutrition on mortality and morbidity among adults living with HIV in SSA were included. Heterogeneity between the included studies was assessed using the Cochrane Q-test and I2 statistics. Publication bias was assessed using Egger’s and Begg’s tests at a 5% significance level. Finally, a random-effects meta-analysis model was employed to estimate the overall adjusted hazard ratio. Results Of 4309 identified studies, 53 articles met the inclusion criteria and were included in this review. Of these, 40 studies were available for the meta-analysis. A meta-analysis of 23 cohort studies indicated that undernutrition significantly (AHR: 2.1, 95% CI: 1.8, 2.4) increased the risk of mortality among adults living with HIV, while severely undernourished adults living with HIV were at higher risk of death (AHR: 2.3, 95% CI: 1.9, 2.8) as compared to mildly undernourished adults living with HIV. Furthermore, the pooled estimates of ten cohort studies revealed that undernutrition significantly increased the risk of developing tuberculosis (AHR: 2.1, 95% CI: 1.6, 2.7) among adults living with HIV. Conclusion This review found that undernutrition has significant effects on mortality and morbidity among adults living with HIV. As the degree of undernutrition became more severe, mortality rate also increased. Therefore, findings from this review may be used to update the nutritional guidelines used for the management of PLHIV by different stakeholders, especially in limited-resource settings.

Survival among antiretroviral-experienced HIV-2 patients experiencing virologic failure with drug resistance mutations in Cote d'Ivoire West Africa. PLoS One 2020; 15:e0236642. [PMID: 32756581 PMCID: PMC7406077 DOI: 10.1371/journal.pone.0236642] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Accepted: 07/09/2020] [Indexed: 11/30/2022] Open
Abstract
INTRODUCTION The long-term prognosis of HIV-2-infected patients receiving antiretroviral therapy (ART) is still challenging, due to the intrinsic resistance to non-nucleoside reverse transcriptase inhibitors (NNRTI) and the suboptimal response to some protease inhibitors (PI). The objective was to describe the 5-years outcomes among HIV-2 patients harboring drug-resistant viruses. METHODS A clinic-based cohort of HIV-2-patients experiencing virologic failure, with at least one drug resistance mutation was followed from January 2012 to August 2017 in Côte d'Ivoire. Follow-up data included death, lost to follow-up (LTFU), immuno-virological responses. The Kaplan-Meier curve was used to estimate survival rates. RESULTS A total of 31 HIV-2 patients with virologic failure and with at least one drug resistance mutation were included. Two-third of them were men, 28(90.3%) were on PI-based ART-regimen at enrolment and the median age was 50 years (IQR = 46-54). The median baseline CD4 count and viral load were 456 cells/mm3 and 3.7 log10 c/mL respectively, and the participants have been followed-up in median 57 months (IQR = 24-60). During this period, 21 (67.7%) patients switched at least one antiretroviral drug, including two (6.5%) and three (9.7%) who switched to a PI-based and an integrase inhibitor-based regimen respectively. A total of 10(32.3%) patients died and 4(12.9%) were LTFU. The 36 and 60-months survival rates were 68.5% and 64.9%, respectively. Among the 17 patients remaining in care, six(35.3%) had an undetectable viral load (<50 c/mL) and for the 11 others, the viral load ranged from 2.8 to 5.6 log10 c/mL. Twelve patients were receiving lopinavir at the time of first genotype, five(42%) had a genotypic susceptibility score (GSS) ≤1 and 4(33%) a GSS >2. CONCLUSIONS The 36-months survival rate among ART-experienced HIV-2 patients with drug-resistant viruses is below 70%,lower than in HIV-1. There is urgent need to improve access to second-line ART for patients living with HIV-2 in West Africa.

Abstract
INTRODUCTION Loss to follow-up (LTFU) rates from antiretroviral treatment (ART) programmes in low- and middle-income countries (LMIC) are high, leading to poor treatment outcomes and onward transmission of HIV. Knowledge of risk factors is required to address LTFU. In this systematic review, risk factors for LTFU are identified and meta-analyses performed. METHODS PubMed, Embase, Psycinfo and Cochrane were searched for studies that report on potential risk factors for LTFU in adults who initiated ART in LMICs. Meta-analysis was performed for risk factors evaluated by at least five studies. Pooled effect estimates and their 95% confidence intervals (95% CI) were calculated using random effect models with inverse variance weights. Risk of bias was assessed and sensitivity analyses performed. RESULTS Eighty studies were included describing a total of 1 605 320 patients of which 87.4% from sub-Saharan Africa. The following determinants were significantly associated with an increased risk of LTFU in meta-analysis: male sex, older age, being single, unemployment, lower educational status, advanced WHO stage, low weight, worse functional status, poor adherence, nondisclosure, not receiving cotrimoxazole prophylactic therapy when indicated, receiving care at secondary level and more recent year of initiation. No association was seen for CD4 cell count, tuberculosis at baseline, regimen, and geographical setting. CONCLUSION There are several sociodemographic, clinical, patient behaviour, treatment-related and system level risk factors for LTFU from ART programs. Knowledge of risk factors should be used to better target retention interventions and develop tools to identify high-risk patients.

Abstract
PURPOSE The 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. PARTICIPANTS IeDEA 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 DATE The 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 PLANS IeDEA 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
In 2007, HIV treatment services were established in five main governorates out of twenty-two which resulted in low access to services and poor treatment outcomes. The main goal of this study was to evaluate and analyse the selected treatment outcomes of eight cohorts of PLHIV who were treated with cART during 2007–2014. The method used was a retrospective descriptive study of 1,703 PLHIV who initiated cART at five public health facilities. The results: Retention rate was less than 80%, male: female ratio 1.661, with a mean age of 35 years (±9.2 SD), 85% had been infected with HIV via heterosexual contact. 65% of patients presented with clinical stages 3 and 4, and 52% of them were initiated cART at a CD4 T-cell count ≤200 cells/mm. 61% of cART included Tenofovir and Efavirenz. TB treatment started for 5% of PLHIV, and 22% developed HIV-related clinical manifestations after cART initiation. 67% of PLHIV had experienced cART substitution. The mean AIDS-mortality rate was 15% and the mean LTFU rate was 16%. Conclusion: Although cART showed effectiveness in public health, mobilization of resources and formulation of better health policies are important steps toward improving access to cART and achieving the desired treatment outcomes.

Abstract
Introduction Le VIH-2, endémique en Afrique de l'Ouest, est naturellement résistant aux inhibiteurs non nucléosidiques de la rétro transcriptase (INNRTI), ce qui rend difficile la prise en charge dans les pays en développement. L’objectif ici était de déterminer la prévalence de l'échec virologique au 12éme et 24éme mois (M12 et M24) de traitement antirétroviral de première ligne chez les patients infectés par le VIH-2 et d'en décrire les résistances génotypiques associées. Méthodes Il s'agit d'une étude descriptive longitudinale et prospective, durant la période de novembre 2005 à juin 2017. L'échec virologique a été défini comme toute charge virale supérieure à 50 copies/ml après 6 mois de traitement ARV à deux reprises. La recherche de mutations de résistance a été réalisée dans les régions codantes de la protéase et de la transcriptase inverse. Résultats Au total 110 patients ont été colligés, d'âge médian de 46 ans (Extrêmes 18-67) avec un ratio F/H de 2,54. À l'inclusion, la charge virale était détectable dans 44% des cas avec une médiane de 935cp/ml (Extrêmes 17-144038). Le schéma antirétroviral associait 2 INTI à 1IP dans 94% des cas. La durée médiane de suivi était estimée à 1200 jours (Extrêmes 1-3840). 94 puis 76 patients ont respectivement complété leur bilan à M12 et M24. Au suivi M24, 39 patients étaient en échec virologique soit une prévalence de 39% estimée à 33% à M12 et 11% à M24. 45% des patients avaient des résistances aux inhibiteurs nucléosidiques de la transcriptase inverse (INTI), 41% des résistances aux IP et 30% des multi résistances aux INTI et IP. Conclusion Il est impératif de rendre accessible les nouvelles classes thérapeutiques pour le traitement de sauvetage des patients infectés par le VIH-2 dans les pays à ressources limitées.

Performance of Bio-Rad HIV-1/2 Confirmatory Assay in HIV-1, HIV-2 and HIV-1/2 dually reactive patients - comparison with INNO-LIA and immunocomb discriminatory assays. J Virol Methods 2019; 268:42-47.

Abstract
BACKGROUND Being able to discriminate between HIV-1, HIV-2 and HIV-1/2 dual infection is imperative for the appropriate selection of antiretroviral therapy (ART) in regions with high HIV-2 endemicity. OBJECTIVES To evaluate Bio-Rad Geenius HIV-1/2 Confirmatory Assay against INNO-LIA HIV 1/2 Score and ImmunoComb HIV 1/2 BiSpot with an emphasis towards ability to discriminate between HIV-1, HIV-2 and HIV-1/2 dual infection. MATERIAL AND METHODS 131 samples from ART naïve HIV infected patients in Guinea-Bissau were selected retrospectively and tested with Geenius, INNO-LIA and Immunocomb. HIV-1/2 RNA were measured in all samples and HIV-1/2 DNA in 59 samples. RESULTS The Geenius reader typed 62 samples as HIV-1 reactive, 37 samples as HIV-2 reactive and 32 samples as HIV-1/2 dually reactive. Geenius manual reading classified 10% more samples as HIV-1/2 dually reactive (n = 35). INNO-LIA typed 63 samples as HIV-1 reactive, 36 samples as HIV-2 reactive and 32 samples as HIV-1/2 dually reactive while Immunocomb classified a large proportion of samples as HIV-1/2 dually reactive (n = 45). The measurement of agreement of the Geenius reader compared with INNO-LIA and Immunocomb was 92.4% and 84.0% respectively while the measurement of agreement of Geenius manual reading compared with INNO-LIA and Immuncomb was 93.1% and 89.3% respectively. CONCLUSIONS Geenius has similar performance characteristics as INNO-LIA, and performs considerably better than Immunocomb, for differentiating between HIV types. This is especially true when using the Geenius reader while manual reading of the Geenius assay seemed to overestimate the numbers of HIV-1/2 dually reactive samples.

Abstract
We examined the antiviral activity of the integrase inhibitor (INI) cabotegravir against HIV-2 isolates from INI-naive individuals. HIV-2 was sensitive to cabotegravir in single-cycle and spreading-infection assays, with 50% effective concentrations (EC50s) in the low to subnanomolar range; comparable results were obtained for HIV-1 in both assay formats. Our findings suggest that cabotegravir should be evaluated in clinical trials as a potential option for antiretroviral therapy and preexposure prophylaxis in HIV-2-prevalent settings.

Abstract
Metabolic syndrome (MetS), a cluster of cardiovascular disease risk factors, is increasingly common in people living with HIV; however, data on prevalence and the role of antiretroviral therapy (ART) as a risk factor for MetS in sub-Saharan Africa are lacking. We conducted a cross-sectional study to assess the prevalence and risk factors for MetS among ART-naive and ART-experienced HIV-infected adults without preexisting cardiometabolic disorders in Western Kenya using validated questionnaires and laboratory tests after overnight fasting. We used logistic regression to identify associations between traditional risk factors, HIV disease characteristics, ART, and MetS. Study participants included 164 ART-experienced patients, majority (56%) on tenofovir/lamivudine/nevirapine regimen, and 136 ART-naive patients. The median age was 40 (interquartile range, 33-46) years and 64% were women. Median HIV infection and ART use were 4.6 (1.7-7.9) and 4.8 (2.7-7.8) years, respectively. Prevalence of MetS did not differ between ART-experienced (16.9%) and -naive (15.2%) groups. ART-experienced patients had higher rates of elevated fasting blood sugars and lower rates of low high-density lipoprotein-cholesterol. The prevalence of abnormal waist circumference, elevated blood pressure, and hypertriglyceridemia were comparable between the two groups. Older age, female sex, and high body mass index were independently associated with diagnosis of MetS. Traditional risk factors rather than ART-related effects were more important predictors of MetS in this cohort and may have been influenced by ART type and exclusion of preexisting hypertension and diabetes. HIV-infected patients without preexisting cardiometabolic disorders should be monitored for metabolic abnormalities regardless of ART.

Abstract
OBJECTIVES Discrimination between HIV-1 and HIV-2 is important to ensure appropriate antiretroviral treatment (ART) and epidemiological surveillance. However, serological tests have shown frequent mistyping when applied in the field. We evaluated two confirmatory tests, INNO-LIA HIV I/II Score and ImmunoComb HIV 1/2 BiSpot, for HIV type discriminatory capacity. METHODS Samples from 239 ART-naïve HIV-infected patients from the Bissau HIV Cohort in Guinea-Bissau were selected retrospectively based on the initial HIV typing performed in Bissau, ensuring a broad representation of HIV types. INNO-LIA results were interpreted by the newest software algorithm, and three independent observers read the ImmunoComb results. HIV-1/HIV-2 RNA and DNA were measured for confirmation. RESULTS INNO-LIA results showed 123 HIV-1 positive samples, 69 HIV-2 positive and 47 HIV-1/2 dually reactive. There was agreement between INNO-LIA and HIV-1/HIV-2 RNA and DNA detection, although not all HIV-1/2 dually reactive samples could be confirmed by the nucleic acid results. Overall, the observers found that the ImmunoComb results differed from the INNO-LIA results, with agreements of 90.4, 91.2 and 92.5%, respectively, for HIV-1, HIV-2 and HIV-1/2. The combined kappa-score for agreement between the three observers was 0.955 (z-score 35.1; P < 0.01). Of the HIV-2 mono-reactive samples (INNO-LIA), the three observers interpreted 24.6-31.9% as HIV-1/2 dually infected by ImmunoComb. None of these samples had detectable HIV-1 RNA or DNA. CONCLUSIONS There was accordance between INNO-LIA calls and nucleic acid results, whereas ImmunoComb overestimated the number of HIV-1/2 dually infected patients. Confirmatory typing is needed for patients diagnosed with HIV-1/2 dual infection by ImmunoComb.

Abstract
BACKGROUND The current challenge in managing people living with human immunodeficiency virus (PLWHIV) includes the identification and monitoring for comorbid health risks associated with HIV and its treatment and longer survival. Dyslipidemia, diabetes mellitus and metabolic syndrome are increasingly seen in PLWHIV. OBJECTIVE In this narrative review, we aimed to summarize the current knowledge about diabetes, dyslipidemia and metabolic syndrome in PLWHIV in Africa and also to discuss the challenges that patients as well as health authorities in Africa may face. METHODS PubMed and Google scholar published-English literatures concerning earlier mentioned entities regardless of time limit were critically reviewed. RESULTS The prevalence of metabolic disorders in HIV population in Africa was estimated to range from 2.1% to 26.5% for diabetes and 20.2% to 43.5% for pre-diabetes, 13% to 58% for metabolic syndrome and 13% to 70% for dyslipidemia. CONCLUSION The management of metabolic disorders and cardiovascular disease risks related to HIV is complex especially in Africa due to healthcare resources, but our experience suggests that metabolic clinic is beneficial to patients and staff and should be an important part of HIV services especially as the older HIV population is increasing. In this context, cardiovascular risk assessment of HIV-infected patients will become an important component of care in developing countries in Africa and strategies are needed to deal with progressive increase in the epidemic of type 2 diabetes, dyslipidemia and metabolic syndrome.
