RESUMO
In Benin, consistent condom use among men who have sex with men (MSM) is relatively low and providing them with Pre-exposure prophylaxis (PrEP) could be of great relevance. We aimed to describe PrEP knowledge and intention to use it; identify key facilitators and barriers to PrEP; and describe the perceived impact of PrEP on unsafe sexual behavior. MSM, 18 years or older, HIV-negative or of unknown status, were enrolled in five cities of Benin. Intention to use PrEP was assessed through five focus groups (FG). Data were analyzed using manual thematic sorting. Thirty MSM (six per city) participated in the FG. Mean age (standard deviation) was 27.1 (5.0) years. All participants expressed the intention to use PrEP if made available. Facilitators of PrEP use were: availability of medication, safety, absence of constraints as well as freedom to have multiple sex partners and sex with HIV-positive friends. Barriers were: complex procedures for obtaining medication, size and taste of medication, cost of medication, poor PrEP awareness.. Eighteen men admitted that PrEP could lead to decrease in or even abandonment of condom use. In conclusion, MSM showed openness to use PrEP if available, although they recognized that it could lead to risk compensation.

BACKGROUND: Approximately 8% of HIV-infected individuals are co-infected with hepatitis B virus (HBV) in sub-Saharan Africa (SSA). Knowledge of HBV status is important to guide optimal selection of antiretroviral therapy (ART) and monitor/prevent liver-related complications. We describe changes in testing practices and management of HBV infection over a 3-year period in HIV clinics across SSA. METHODS: A medical chart review was conducted in large urban HIV treatment centers in Côte d'Ivoire (3 sites), Benin, Burkina Faso, Cameroon, Kenya, Senegal, South Africa, Togo, Uganda and Zambia (1 site each). Of the patients who started ART between 2010 and 2012, 100 per year were randomly selected from each clinic. Demographic, clinical and laboratory information as well as individual treatment histories were collected using a standardized questionnaire. We examined changes over time in the proportion of patients screened for HBV infection (HBV surface antigen [HBsAg]-positivity), identified predictors of HBV testing using logistic regression, and assessed the proportion of patients initiating a tenofovir (TDF)-containing ART regimen. RESULTS: Overall, 3579 charts of patients initiating ART (64.4% female, median age 37 years) were reviewed in 12 clinics. The proportion of patients screened for HBsAg increased from 17.8% in 2010 to 24.4% in 2012 overall, and ranged from 0.7% in Kenya to 96% in South Africa. In multivariable analyses, age and region were associated with HBsAg screening. Among 759 individuals tested, 88 (11.6%; 95% confidence interval [CI] 9.4-14.1) were HBV-infected, of whom 71 (80.7%) received a TDF-containing ART regimen. HBsAg-positive individuals were twice as likely to receive a TDF-containing first-line ART regimen compared to HBsAg-negative patients (80.7% vs. 40.3%, p < 0.001). The proportion of patients on TDF-containing ART increased from 57.9% in 2010 to 90.2% in 2012 in HIV/HBV-co-infected patients (Chi-2 test for trend: p = 0.01). Only 114 (5.0%) patients were screened for anti-HCV antibodies and one of them (0.9%, 95% CI 0.02-4.79) had a confirmed HCV infection. CONCLUSIONS: The systematic screening for HBV infection in HIV-positive patients before ART initiation was limited in most African countries and its uptake varied widely across clinics. Overall, the prescription of TDF increased over time, with 90% of HIV/HBV-coinfected patients receiving this drug in 2012.

INTRODUCTION: In sub-Saharan Africa (SSA), the physicians' ratio is increasing. There are clear indications that many of them have opted to work at the first-line of healthcare delivery systems, i.e. providing primary care. This constitutes an important change in African healthcare systems where the first line has been under the responsibility of nurse-practitioners for decades. Previous reviews on primary care physicians (PCPs) in SSA focused on the specific case of family physicians in English-speaking countries. This scoping review provides a broader mapping of the PCPs' practices in SSA, beyond family physicians and including francophone Africa. For this study, we defined PCPs as medical doctors who work at the first-line of healthcare delivery and provide generalist healthcare. METHODS: We searched five databases and identified additional sources through purposively selected websites, expert recommendations, and citation tracking. Two reviewers independently selected studies and extracted and coded the data. The findings were presented to a range of stakeholders. FINDINGS: We included 81 papers, mostly related to the Republic of South Africa. Three categories of PCPs are proposed: family physicians, "médecins généralistes communautaires", and general practitioners. We analysed the functioning of each along four dimensions that emerged from the data analysis: professional identity, governance, roles and activities, and output/outcome. Our analysis highlighted several challenges about the PCPs' governance that could threaten their effective contribution to primary care. More research is needed to investigate better the precise nature and performance of the PCPs' activities. Evidence is particularly needed for PCPs classified in the category of GPs and, more generally, PCPs in African countries other than the Republic of South Africa. CONCLUSIONS: This review sheds more light on the institutional, organisational and operational realities of PCPs in SSA. It also highlighted persisting gaps that remain in our understanding of the functioning and the potential of African PCPs.

INTRODUCTION: Sex differences have already been reported in sub-Saharan Africa for attrition and immunological response after antiretroviral therapy (ART) initiation, but follow-up was usually limited to the first two to three years after ART initiation. We evaluated sex differences on the same outcomes in the 10 years following ART initiation in West African adults. METHODS: We used cohort data of patients included in the IeDEA West Africa collaboration, who initiated ART between 2002 and 2014. We modelled no-follow-up and 10-year attrition risks, and immunological response by sex using logistic regression analysis, survival analysis with random effect and linear mixed models respectively. RESULTS: A total of 71,283 patients (65.8% women) contributed to 310,007 person-years of follow-up in 16 clinics in eight West African countries. The cumulative attrition incidence at 10-year after ART initiation reached 75% and 68% for men and women respectively. Being male was associated with an increased risk of no follow-up after starting ART (5.1% vs. 4.0%, adjusted Odds Ratio: 1.25 [95% CI: 1.15 to 1.35]) and of 10-year attrition throughout the 10-year period following ART initiation: adjusted Hazard Ratios were 1.22 [95% CI: 1.17 to 1.27], 1.08 [95% CI: 1.04 to 1.12] and 1.04 [95% CI: 1.01 to 1.08] during year 1, years 2 to 4 and 5 to 10 respectively. A better immunological response was achieved by women than men: monthly CD4 gain was 30.2 and 28.3 cells/mL in the first four months and 2.6 and 1.9 cells/µL thereafter. Ultimately, women reached the average threshold of 500 CD4 cells/µL in their sixth year of follow-up, whereas men failed to reach it even at the end of the 10-year follow-up period. The proportion of patients reaching the threshold was much higher in women than in men after 10 years since ART initiation (65% vs. 44%). CONCLUSIONS: In West Africa, attrition is unacceptably high in both sexes. Men are more vulnerable than women on both attrition and immunological response to ART in the 10 years following ART initiation. Innovative tracing strategies that are sex-adapted are needed for patients in care to monitor attrition, detect early high-risk groups so that they can stay in care with a durably controlled infection.

OBJECTIVES: Female sex workers (FSWs) play a key role in HIV transmission in West Africa, while they have limited access to antiretroviral therapy (ART). In line with UNAIDS recommendations extending ART to all HIV-infected individuals, we conducted this demonstration project on immediate treatment as prevention (TasP) among FSWs in Cotonou, Benin. We report data on treatment response and its relation to adherence, as well as on ART-resistant genotypes. METHODS: Complete follow-up varied between 12 and 24 months. At each three-monthly visit, a questionnaire was administered, clinical examinations were carried out and blood samples collected. Adherence to treatment was estimated by self-report. Viral RNA was genotyped at baseline and final visits for drug resistance. Generalized estimating equations for repeated measures with a log-binomial link were used to analyze time trends and the association between adherence and virological response to treatment. RESULTS: One-hundred-seven HIV-positive and ART-naive FSWs were enrolled; 59.8% remained in the cohort till study completion and 62.6% had a final visit. Viral load<1000 (below quantification limit [<50]) was attained in 73.1% (64.6%) of participants at month-6, 84.8% (71.2%) at month-12, and 80.9% (65.1%) at the final visit. The proportion of women with suppressed (below quantification limit) viral load increased with increasing self-reported adherence (p = 0.06 (0.003), tests for trend). The proportion of participants with CD4≤500 also decreased drastically throughout follow-up (p < .0001). Twelve participants exhibited ART-resistant genotypes at baseline, but only two at their final visit. CONCLUSION: Our findings indicate that TasP is widely accepted among FSWs in Cotonou and could be implemented with relative success. However, due to mobility in this population, follow-up was sub-optimal, suggesting that large geographical coverage of FSW-friendly clinics is needed for sustained treatment implementation. We also fell short of the UNAIDS objective of 90% viral suppression among treated patients, underlining the need for better adherence support programs.

This article reviews the prevention of mother-to-child HIV transmission programme (PMTCT) in Benin. A survey was conducted in the 56 PMTCT sites of the country among health providers and beneficiaries. 39,000 pregnant women were tested per year in these sites (3.9% were HIV-positive) and 1,120 infected women have received the protocol (single-dose nevirapine), which corresponds to a national coverage rate of 16%. The investigation revealed shortcomings of the programme, notably the variation in the cost of prenatal consultations, HIV tests were frequently out of stock, lack of adherence to PMTCT recommendations and neglect of concern for the future of mothers and their children, supervision was not sufficiently pragmatic and PMTCT lacked linkages with the maternal and child health programme. This context should be taken into consideration when discussing the extension of PMTCT to new sites and the introduction of more active antiretroviral regimen.

BACKGROUND: In sub-Saharan Africa, antiretroviral therapy (ART) including drugs with potential toxicity such as Zidovudine (ZDV) are routinely prescribed. This study aimed at estimating the incidence of severe neutropenia and associated factors after ART initiation in five West African countries. METHODS: A retrospective cohort analysis was conducted within the international epidemiologic database to evaluate AIDS (IeDEA) collaboration in West Africa. All HIV-infected adults, initiating ART between 2002 and 2014, with a baseline and at least one follow-up absolute neutrophil count (ANC) measurement were eligible. Incidence of severe neutropenia (ANC <750 cells/mm3) was estimated with 95% confidence interval (CI) according to age, gender, HIV clinic, hemoglobin, CD4 count, clinical stage, and ART duration. A Cox proportional hazard model was used to identify factors associated with severe neutropenia, expressed with their adjusted hazard ratios (aHR). RESULTS: Between 2002 and 2014, 9,426 HIV-infected adults were enrolled. The crude incidence rate of a first severe neutropenia was 9.1 per 100 person-years (95% CI: 8.6-9.8). Factors associated with severe neutropenia were exposure to ZDV <6 months (aHR = 2.2; 95% CI: 1.8-2.6), ≥6-12 months (aHR = 2.1; 95% CI: 1.6-2.8) and ≥12 months (aHR = 1.6; 95% CI: 1.2-2.2) [Ref. no ZDV exposure], CD4 count <350 cells/mm3 (aHR = 1.3; 95% CI: 1.1-1.5) and advanced clinical stage at ART initiation (aHR = 1.2; 95% CI: 1.0-1.4). CONCLUSION: The incidence of severe neutropenia after ART initiation in West Africa is high and associated with ZDV exposure and advanced HIV disease. In this context, efforts are needed to scale-up access to less toxic first-line ART drugs and to promote early ART initiation.

BACKGROUND: High risk oncologic Human Papilloma Virus (HPV) is one of the leading causes of cervical cancer worldwide. We investigated HPV genotypes among women living or not with Human Immuno-deficiency Virus (HIV) in two major hospitals in the south of the republic of BENIN in the city of Cotonou. Our objective is to investigate the association of high risk-HPV to cervical dysplasia among women under stringent anti-retroviral (ARV) treatment and in controls without HIV. METHODS: The investigation was carried out within 1 year period in two groups of adult women: one group with HIV1 infection and under ARV therapy in the National University Hospital (CNHU-HKM) designated as CH group (n = 86); and one control group without HIV infection and attending the hospital Mènontin for routine gynecologic checkup and designated as ME group (n = 86). Cells derived from cervical uterine smears (CUS) were used for this investigation. The samples in ME group were selected to have similar lamin A/C profile with CH group. HPV genotypes were assessed by polymerase chain reaction (PCR) while lamin A/C expression profile was assessed by western blotting to corroborate the risk of cervical dysplasia. RESULTS: HPV56 is dominant in CH group while HPV66 is dominant in ME group. 31 % of women in CH group are infected with HPV compared to 23 % in ME group. Quadruple and quintuple HPV infections are more observed among CH group but not in ME group making HPV counts of 43 in CH group and 27 in ME group. Cervical dysplasia are present in 5 % (4/86) of women in CH group and in 1 % (1/86) of women in ME group at the time of CUS collection. The adjustment of the risk to develop cervical cancer in the future related to HPV infection and the total loss of lamin A/C is not significantly different in both groups. CONCLUSION: Women living with HIV are more sensitive to multiple HPV infection but not all HPV infections generated cervical dysplasia. The effectiveness of antiretroviral therapy in CH group may reduce significantly the frequency of cervical dysplasia.
RESUMO
The consequences of the HIV epidemic on cancer epidemiology are sparsely documented in Africa. We aimed to estimate the association between HIV infection and selected types of cancers among patients hospitalized for cancer in four West African countries. A case-referent study was conducted in referral hospitals of Benin, Côte d'Ivoire, Nigeria and Togo. Each participating clinical ward included all adult patients seeking care with a confirmed diagnosis of cancer. All patients were systematically screened for HIV infection. HIV prevalence of AIDS-defining and some non-AIDS defining cancers (Hodgkin lymphoma, leukemia, liver, lung, skin, pharynx, larynx, oral cavity and anogenital cancers) were compared to a referent group of cancers reported in the literature as not associated with HIV. Odds ratios adjusted on age, gender and lifetime number of sexual partners (aOR) and their 95% confidence intervals (CI) were estimated. Among the 1644 cancer patients enrolled, 184 (11.2%) were identified as HIV-infected. The HIV prevalence in the referent group (n=792) was 4.4% [CI 3.0-5.8]. HIV infection was associated with Kaposi sarcoma (aOR 34.6 [CI: 17.3-69.0]), non-Hodgkin lymphoma (aOR 3.6 [CI 1.9-6.8]), cervical cancer (aOR 4.3 [CI 2.2-8.3]), anogenital cancer (aOR 17.7 [CI 6.9-45.2]) and squamous cell skin carcinoma (aOR 5.2 [CI 2.0-14.4]). A strong association is now reported between HIV infection and Human Papillomavirus (HPV)-related cancers including cervical cancer and anogenital cancer. As these cancers are amenable to prevention strategies, screening of HPV-related cancers among HIV-infected persons is of paramount importance in this African context.

Melorheostosis is a rare chronic bone disease of unknown etiology that often affects a single limb. Onset usually occurs in childhood or early adolescence. A flowing wax appearance along the surface of the bone and multiple areas of bone sclerosis produce a typical radiographic picture. We describe the first case reported in a black African, in whom an exceedingly rare feature was a bilateral distribution of the lesions.

INTRODUCTION: This study aimed at estimating the incidence of pregnancy after antiretroviral therapy (ART) initiation in 8 West African countries over a 10-year period. METHODS: A retrospective analysis was conducted within the international database of the IeDEA West Africa Collaboration. All HIV-infected women aged <50 years and starting ART for their own health between 1998 and 2011 were eligible. Pregnancy after ART initiation was the main outcome and was based on clinical reporting. Poisson regression analysis accounting for country heterogeneity was computed to estimate first pregnancy incidence post-ART and to identify its associated factors. Pregnancy incidence rate ratios were adjusted on country, baseline CD4 count and clinical stage, hemoglobin, age, first ART regimen, and calendar year. RESULTS: Overall, 29,425 HIV-infected women aged 33 years in median (interquartile range, 28-38) contributed for 84,870 women-years of follow-up to this analysis. The crude incidence of first pregnancy (2304 events) was 2.9 per 100 women-years [95% confidence interval (CI): 2.7 to 3.0], the highest rate being reported among women aged 25-29 years: 4.7 per 100 women-years; 95% CI: 4.3 to 5.1. The overall Kaplan-Meier probability of pregnancy occurrence by the fourth year on ART was 10.9% (95% CI: 10.4 to 11.4) and as high as 28.4% (95% CI: 26.3 to 30.6) among women aged 20-29 years at ART initiation. CONCLUSIONS: The rate of pregnancy occurrence after ART initiation among HIV-infected women living in the West Africa region was high. Family planning services tailored to procreation needs should be provided to all HIV-infected women initiating ART and health consequences carefully monitored in this part of the world.

The purpose of this study is to determine the level of knowledge and the means of communication for early detection of diabetic nephropathy. This is a prospective study which took place from 6 February to 31 May 2012, in the Academic Clinics of Nephrology-Hemodialysis and the Endocrinology and Metabolic Diseases. Included all patients with diabetes mellitus in two sexes, older than fifteen years and hospitalized in one of these two clinicals or received in consultation during the study period. A questionnaire is used for data collection. Statistical analysis was performed by STATA 11(®) in its English version. One hundred and sixty patients were enrolled. More than 4 out of 5 patients had reported knowledge of diabetes mellitus while only 26.67% had acknowledged that manifests itself by high glycemia. More than half of the patients (57.50%) had said that diabetes mellitus can be complicated by renal impairment. Three out of four diabetics (75.63%) didn't know that it is possible to make an early diagnosis of diabetic nephropathy. The radio and television broadcasts, and sensitizations during medical consultations represented the best means of communication for early detection of diabetic nephropathy. The combination of several means of communication will raise awareness on early detection of diabetic nephropathy.

A common idiotype of anti-HIV antibodies (Abs), designated as 1F7, was recently observed on anti-HIV broadly neutralizing Abs (BnAbs). The presence of the 1F7-idiotype on BnAbs suggests that continuous selection of 1F7-idiotypic Abs may allow these clones to achieve the somatic hypermutation necessary for broad neutralization. As the selection of type-specific BnAbs occurs in the setting of infections with a wide array of HIV subtypes, we investigated Abs from subjects infected with diverse subtypes for the selection of 1F7-idiotypic Abs. We observed the 1F7-idiotype on antiviral Abs in infections with various HIV subtypes. Furthermore, gp140-specific 1F7-idiotypic Abs recognized the gp140 antigens from several HIV subtypes. These results demonstrate that the 1F7-idiotype is a common characteristic of Abs from infections with diverse HIV subtypes, and suggests that early cross-reactivity of 1F7-idiotypic clones may act in conjunction with somatic hypermutation to produce BnAbs.

BACKGROUND: Cancer is a growing co-morbidity among HIV-infected patients worldwide. With the scale-up of antiretroviral therapy (ART) in developing countries, cancer will contribute more and more to the HIV/AIDS disease burden. Our objective was to estimate the association between HIV infection and selected types of cancers among patients hospitalized for diagnosis or treatment of cancer in West Africa. METHODS: A case-referent study was conducted in referral hospitals in Côte d'Ivoire and Benin. Each participating clinical ward enrolled all adult patients seeking care for a confirmed diagnosis of cancer and clinicians systematically proposed an HIV test. HIV prevalence was compared between AIDS-defining cancers and a subset of selected non-AIDS defining cancers to a referent group of non-AIDS defining cancers not reported in the literature to be positively or inversely associated with HIV. An unconditional logistic model was used to estimate odds ratios (OR) and their 95% confidence intervals (CI) of the risk of being HIV-infected for selected cancers sites compared to a referent group of other cancers. RESULTS: The HIV overall prevalence was 12.3% (CI 10.3-14.4) among the 1,017 cancer cases included. A total of 442 patients constituted the referent group with an HIV prevalence of 4.7% (CI 2.8-6.7). In multivariate analysis, Kaposi sarcoma (OR 62.2 [CI 22.1-175.5]), non-Hodgkin lymphoma (4.0 [CI 2.0-8.0]), cervical cancer (OR 7.9 [CI 3.8-16.7]), anogenital cancer (OR 11.6 [CI 2.9-46.3]) and liver cancer (OR 2.7 [CI 1.1-7.7]) were all associated with HIV infection. CONCLUSIONS: In a time of expanding access to ART, AIDS-defining cancers remain highly associated with HIV infection. This is to our knowledge, the first study reporting a significant association between HIV infection and liver cancer in sub-Saharan Africa.

BACKGROUND: Most HIV infections are transmitted across mucosal epithelium. Understanding the role of innate and specific mucosal immunity in susceptibility or protection against HIV infection, as well as the effect of HIV infection on mucosal immunity, are of fundamental importance. HLA-G is a powerful modulator of the immune response. The aim of this study was to investigate whether soluble HLA-G (sHLA-G) expression in the female genital tract is associated with HIV-1 infection. METHODS AND FINDINGS: Genital levels of sHLA-G were determined in 52 HIV-1-uninfected and 44 antiretroviral naïve HIV-1-infected female commercial sex workers (CSWs), as well as 71 HIV-1-uninfected non-CSW women at low risk of exposure, recruited in Cotonou, Benin. HIV-1-infected CSWs had higher genital levels of sHLA-G compared with those in both the HIV-1-uninfected CSW (Pâ=â0.009) and non-CSW groups (Pâ=â0.0006). The presence of bacterial vaginosis (Pâ=â0.008), and HLA-G*01:01:02 genotype (Pâ=â0.002) were associated with higher genital levels of sHLA-G in the HIV-1-infected CSWs, whereas the HLA-G*01:04:04 genotype was also associated with higher genital level of sHLA-G in the overall population (Pâ=â0.038). When adjustment was made for all significant variables, the increased expression of sHLA-G in the genital mucosa remained significantly associated with both HIV-1 infection (Pâ=â0.02) and bacterial vaginosis (Pâ=â0.03). CONCLUSION: This study demonstrates that high level of sHLA-G in the genital mucosa is independently associated with both HIV-1 infection and bacterial vaginosis.

AIM: To investigate the association between alcohol use and adherence to highly active antiretroviral treatment (HAART) among human immunodeficiency virus (HIV)-infected patients in sub-Saharan Africa. DESIGN AND SETTING: Cross-sectional survey conducted in eight adult HIV treatment centres from Benin, Côte d'Ivoire and Mali. Participants and measurements During a 4-week period, health workers administered the Alcohol Use Disorders Identification Test to HAART-treated patients and assessed treatment adherence using the AIDS Clinical Trials Group follow-up questionnaire. FINDINGS: A total of 2920 patients were enrolled with a median age of 38 years [interquartile range (IQR) 32-45 years] and a median duration on HAART of 3 years (IQR 1-4 years). Overall, 91.8% of patients were identified as adherent to HAART. Non-adherence was associated with current drinking [odds ratio (OR) 1.4; 95% confidence interval (CI) 1.1-2.0], hazardous drinking (OR 4.7; 95% CI 2.6-8.6) and was associated inversely with a history of counselling on adherence (OR 0.7; 95% CI 0.5-0.9). CONCLUSIONS: Alcohol consumption and hazardous drinking is associated with non-adherence to HAART among HIV-infected patients from West Africa. Adult HIV care programmes should integrate programmes to reduce hazardous and harmful drinking.

AIM: The aim of this retrospective study was to evaluate the use and appropriateness of preventive measures for venous thrombosis among adult inpatients in a Benin teaching hospital. PATIENTS AND METHODS: All patients were systematically enrolled. The risk of venous thrombosis was estimated according to international guidelines. Thromboembolic events were diagnosed using the Wells score and, when possible, by paraclinical investigations. The following variables were studied: the risk of venous thrombosis, the use and appropriateness of preventive measures, and the frequency of thromboembolic events. The data were analyzed with Epiinfo 6.04.fr and SPSS software, and significance was assumed at p=0.05. RESULTS: The study population consisted of 487 patients recruited in four surgical wards, four general wards and one obstetric-gynecology ward. Mean age was 38.7+/-11.3 years and the sex ratio 0.51. The risk of thrombosis was considered low in 15% of patients, moderate in 60.8%, high in 21.1% and very high in 3.1%. Prophylactic measures were prescribed to 33.9% of the patients overall, 53.6% in the obstetric gynecology ward, 28.5% in the surgical wards and 12.9% in the general wards. The frequency of preventive measures rose with the level of risk (p<0.0001). Preventive measures consisted of passive mobilization, aspirin, enoxaparin and acenocoumarol. The prescriptions were appropriate in only 6% of cases. Among 198 patients who were monitored for two months after hospital discharge, 8% had a venous thromboembolic event. Such events were more frequent in the absence of prophylaxis (12% vs 3.3%, p=0.02). CONCLUSION: The risk of venous thromboembolic is recognized but poorly managed in this Bénin teaching hospital.
