[Accessibility of early infant diagnosis of HIV infection in Lome (Togo)]. / Accessibilité au diagnostic précoce de l'infection à VIH chez les enfants à risque de Lomé (Togo).

BACKGROUND: Early infant diagnosis of HIV is the key step for the early initiation of HAART among HIV-exposed children. The aim of this study was to estimate the proportion of children born to mothers infected with HIV who completed the early infant HIV diagnosis process and the factors associated with this complete process. METHODS: We conducted a retrospective cohort study at Tokoin University Hospital in the pediatrics ward. This study included all HIV-exposed children born between July 2009 and June 2011. The association between the mother's, spouse's, and child's characteristics as well as access to early HIV diagnosis by PCR (blood collection and reporting of results before the 6months of age) was studied using logistic regression analysis. RESULTS: A total of 455 HIV-exposed children were included: for 52.7%, the first test was PCR, 99 of them received their results, 59 of whom received their results before the 6th month of life (undergoing the complete process). In multivariate analysis, the only factor associated with the complete process of early HIV diagnosis was the maternal age≥28years (adjusted odds ratio, 1.75, 95% CI [1.18-2.76]). CONCLUSION: The availability of early infant PCR diagnosis remains a challenge and innovative strategies must be implemented.

[HIV seroprevalence and associated factors among men who have sex with men in Togo]. / Séroprévalence du VIH et facteurs associés chez les hommes ayant des rapports sexuels avec d'autres hommes au Togo.

BACKGROUND: Limited data are available on HIV infection among vulnerable populations in sub-saharan African countries, especially among men who have sex with men (MSM). The aim of this study was to estimate HIV prevalence and the factors associated with HIV infection among MSM in Togo in 2011. METHOD: A cross-sectional survey was carried out among MSM aged at least 18years old, living in Togo for at least 3months. They were recruited through the snowball method in six cities of Togo from November 2011 to January 2012. A survey form was used and an HIV screening test was proposed to the participants. The HIV prevalence was estimated with a 95% confidence interval. Univariate and multivariate analyses were performed to identify factors associated with HIV infection. RESULTS: A total of 758 MSM were enrolled in this study, including 498 (67.5%) from Lomé, the capital of Togo. The median age was 24years with an interquartile range of [21-27years] and 271 MSM (35.7%) were students. The vast majority of MSM were Togolese (90.3%) and 14.6% were married or committed to a woman. HIV testing was accepted by 488 MSM (64.3%) but only 408 (53.8%) finally accepted a blood sample collection. The prevalence of HIV infection was 19.6% [95% confidence interval, 15.9-23.8]. In multivariate analysis, three factors were associated with HIV infection: living in Lomé, with an HIV prevalence of 29.8% against 4.3% in the other cities of Togo [adjusted odds ratio (aOR)=9.68; P<0.001]; having a good knowledge of HIV transmission modes (aOR=0.59; P=0.049); and not having a regular sex partner (aOR=1.69; P=0.049). CONCLUSION: One MSM out of five was HIV-infected. Intervention programs targeting this vulnerable population are urgently needed, to reduce HIV incidence in Togo.

[Serologic and genomic research by PCR of hepatitis C virus in different populations in Lomé (Togo)]. / Recherche sérologique et génomique par PCR du virus de l'hépatite C dans différentes populations à Lomé (Togo).

An epidemiological survey carried out on several groups at University Hospital of Lome showed that the prevalence of anti-HCV antibodies is 3.3 % among blood donors, 1.3 % in STD positive subjects and 6.1 % in hospitalized patients. The disparity of the HCV seropositivity rate was not statistically significant among HIV-infected and non-infected subjects (6.9 % vs 3.3 % respectively). The HCV RNA was most frequently recovered from patients, whose serological pattern was confirmed but also from 30 % of subjects, for whom the HCV serology was proved. This shows the limits of serological tests in Africa.
