ObjectiveTo investigate the factors associated with HIV1 RNA plasma viral load (pVL) below 40 copies/mL at the third trimester of pregnancy, as part of prevention of mother-to-child transmission (PMTCT) in Benin.DesignSub study of the PACOME clinical trial of malaria prophylaxis in HIV-infected pregnant women, conducted before and after the implementation of the WHO 2009 revised guidelines for PMTCT.MethodsHIV-infected women were enrolled in the second trimester of pregnancy. Socio-economic characteristics, HIV history, clinical and biological characteristics were recorded. Malaria prevention and PMTCT involving antiretroviral therapy (ART) for mothers and infants were provided. Logistic regression helped identifying factors associated with virologic suppression at the end of pregnancy.ResultsOverall 217 third trimester pVLs were available, and 71% showed undetectability. Virologic suppression was more frequent in women enrolled after the change in PMTCT recommendations, advising to start ART at 14 weeks instead of 28 weeks of pregnancy. In multivariate analysis, Fon ethnic group (the predominant ethnic group in the study area), regular job, first and second pregnancy, higher baseline pVL and impaired adherence to ART were negative factors whereas higher weight, higher antenatal care attendance and longer ART duration were favorable factors to achieve virologic suppression.ConclusionsThis study provides more evidence that ART has to be initiated before the last trimester of pregnancy to achieve an undetectable pVL before delivery. In Benin, new recommendations supporting early initiation were well implemented and, together with a high antenatal care attendance, led to high rate of virologic control.

Introduction: Malaria particularly affects children in sub-Saharan African countries. This study aimed to investigate the factors associated with death in cases of severe childhood malaria to better understand the determinants of death in these children. Patients and Methods: This cohort, descriptive and analytical study was conducted from April 1 to August 15, 2015, at the CNHU-HKM pediatric clinic in Cotonou. Recruitment was exhaustive for all patients under 15 years of age who were admitted for severe malaria, as confirmed by thick smear microscopy. Results: Among the 1774 admitted patients, 449 had severe malaria caused by Plasmodium falciparum (i.e., a hospital frequency of 25.31%).The age group most affected consisted of children younger than 60 months of age (73%); female predominance was noted. The lethality rate of malaria was 13.1% (n = 59). The factors associated with death were coma (p = 0.032), poor convulsive status epilepticus (p = 0.08) and bacterial co-infection by gram negative bacteria (p = 0.021) with respectively correlations coefficient of 0.003, 3.940 and 2.424. Conclusion: Reduction of the malaria mortality rates in Benin hospitals will depend on appropriate management of poor prognostic factors, such as coma, bacterial co-infection and convulsive illness.

The goal of this study was to evaluate using the molecular diagnosis, infection transmission rate of HIV in children born to HIV-1 positive mothers as part of the prevention of mother-to-child transmission (PMTCT) in Benin. The sample consisted of 524 dried blood spots (DBS) of children born to HIV-1 positive mothers, from 30 sites (PMTCT) taken between October 2009 and June 2010. The diagnosis of HIV-1 was performed by the qualitative detection of viral nucleic acids (RNA and DNA) in DBS on filter paper using the Abbott RealTime(®) HIV-1 Qualitative assay. We found that 51 DBS were positive (9.7%) and 473 were negative (90.3%). The failure rate of PMTCT among 420 mothers who received antiretroviral prophylaxis was 6.7% (28/420). This failure rate was significantly higher among children born to infected mothers on antiretroviral monotherapy than on triple therapy (HAART). The results of our study enrich the data in the literature on highly active antiretroviral chemoprophylaxis to reduce the transmission of HIV-1 from mother to child.
