Evolution of HIV prevalence and behavioral factors among MSM in Togo between 2011 and 2015.

INTRODUCTION: The aim of this study was to assess sexual behavior and measure HIV prevalence among MSM in 2015, in Togo. METHODS: We conducted a cross-sectional study from February to March 2015 in nine major cities of Togo. The respondent-driven sampling method was used to recruit MSM. Behavioral data were collected by interviewer-administered questionnaires. The blood tests were then carried out among MSM to assess their HIV status. Data were inputted into an Epidata database and exported to STATA® 9.0 for analysis. Qualitative variables were compared using the chi-2. RESULTS: A total of 496 MSM were involved in this study, with 43.35% in the capital, Lome. Over the past 12 months, 88.9% of MSM had had sexual intercourse with men and 24.1% of them had had sex with women. The last sexual intercourse was with a casual partner among 52.9% of MSM. During the last 30 days preceding the survey, 68.5% of MSM had regularly used a condom during active anal intercourse and 71.9% had used it during passive anal intercourse. The national prevalence rate of HIV among MSM was 13.0%. The factors associated with HIV infection were age of MSM OR = 5.30 [1.85-15.1], HIV testing history OR = 2.63 [1.18-5.87] and the city of residence of MSM OR = 5.56 [2.90-10.64]. CONCLUSION: This study confirms that HIV prevalence among MSM is five times higher than in the general population (13% vs 2.5%). Thus, the need to rethink HIV sensitization and prevention strategies targeting hidden and stigmatized populations such as MSM.

Risk factors associated with abscess formation among patient with leg erysipelas (cellulitis) in sub-Saharan Africa: a multicenter study.

BACKGROUND: Abscess formation is a frequent local complication of leg erysipelas. In this study we aimed at identifying factors associated with abscess formation of leg erysipelas in patients in sub-Saharan African countries. METHOD: This is a multicenter prospective study conducted in dermatology units in eight sub-Saharan African countries from October 2013 to September 2014. We performed univariate and multivariate analysis to compare characteristics among the group of patients with leg erysipelas complicated with abscess against those without this complication. RESULTS: In this study, 562 cases of leg erysipelas were recruited in the eight sub-Saharan African countries. The mean age of patients was 43.67 years (SD =16.8) (Range: 15 to 88 years) with a sex-ratio (M/F) of 5/1. Out of the 562 cases, 63 patients (11.2%) had abscess formation as a complication. In multivariate analysis showed that the main associated factors with this complication were: nicotine addiction (aOR = 3.7; 95 % CI = [1.3 - 10.7]) and delayed antibiotic treatment initiation (delay of 10 days or more) (aOR = 4.6; 95 % CI = [1.8 - 11.8]). CONCLUSION: Delayed antibiotics treatment and nicotine addiction are the main risk factors associated with abscess formation of leg erysipelas in these countries. However, chronic alcohol intake, which is currently found in Europe as a potential risk factor, was less frequent in our study.

Distribution of new HIV infections among key risk population groups in Togo.

INTRODUCTION: Good data on the epidemiology of modes of transmission of HIV among population at risk are important for development of prevention strategies, and resource allocation for the implementation of the interventions. We sought to estimate new HIV infections among key risk groups in Togo. METHODS: We conducted a systematic review of epidemiological data on HIV and AIDS as part of the HIV control strategies in Togo from 2001 to 2012 following the PRISMA guidelines. We used the Mode of Transmission (MoT) modelling tool to estimate the incidence of new HIV infections in high risk groups. The MoT tool was developed and validated by UNAIDS and implemented by several countries using data on the HIV epidemic to estimate new HIV infections that will appear in the core groups. We used Epi-MoT tool to assess the availability and the quality of data. A score of availability of data over 50% and the quality over 1.5 were required to proceed to the MoT analysis. Uncertainty analysis to assess the reliability of the results was performed. RESULTS: Incidence of new HIV infections was estimated at 6,643 (95% CI = 5274, 9005) with an incidence rate of 203 per 1,000,000 inhabitants. The proportion of new HIV infections was 61.9% (95% CI = 46.2 to 71.7) in stable heterosexual couples compare to 14.01% (95% CI = 7.2 to 23.3) in people having casual sex. In high-risk groups new HIV infections accounted for 2.4% among sex workers (SWs) (95% CI = 1.2 - 4.1), 7.9% among clients of SWs (95% CI = 3.9-14.1) and 6.9% among men who have sex with men (MSM) (95% CI = 3.1 to 13.1). CONCLUSION: We describe the prediction of the HIV epidemic with a large contribution of stable heterosexual couples in the occurrence of new infections. But HIV incidence remains high in key risk populations. Innovative strategies for risk reduction should be strengthened to reduce the transmission especially in stable heterosexual couples.

Loss of HIV-infected patients on potent antiretroviral therapy programs in Togo: risk factors and the fate of these patients.

INTRODUCTION: National programs are facing challenges of loss to follow-up of people living with HIV/AIDS (PLWHA) on antiretroviral therapy (ART). We sought to identify risk factors associated with early loss to follow-up among HIV-infected patients on ART in Togo and the outcome of such patients. METHODS: This was a retrospective cross-sectional study using medical records of all patients older than age 15 years enrolled at 28 treatment centers who were on ART programs and who were lost to follow-up from 2008 to 2011. RESULTS: Of the 16,617 patients on ART, 1,216 (7.3%) were lost to follow-up. Most (94.1%) were infected with HIV-1 and 32.6% were in WHO stage III or IV. The median CD4 count was 118/mm3 (IQR: 58-178 cells/mm3). No telephone number was mentioned in the medical records of 212 patients. Of the 1004 patients whose phone number was listed, 802 patients (79.9%) were not reachable on the recorded number, 114 patients (11.4%) were alive and 88 patients (8.8%) had died. In multivariate analysis, factors associated with loss to follow-up during the first 6 months of ART were: age below 35 years (OR = 1.6; 95%CI: 1.2-2.2), female sex (OR = 1.8; 95%CI: 1.3-2.5), WHO stage III or IV (OR = 1.7; 95%CI: 1.3-2.2), existence of an opportunistic infection (OR = 2.3; 95%CI: 1.5-3.1), and follow-up in a public centre (OR = 1.9; 95%CI: 1.2-3.3). CONCLUSION: This study identified several factors associated with lost to follow-up during the first 6 months of ART, and confirmed high mortality among these patients. The National AIDS Program should strengthen medical support of PLWHA in Togo including active case follow-up.
