ABSTRACT
BACKGROUND: Prevention of mother-to-child transmission (PMTCT) programs have been largely scaled-up, but data on infant HIV drug resistance from PMTCT programs implemented in resource-limited countries are lacking. METHODS: Remnant dried blood spots from HIV-infected children (aged <18 months) tested through the Togo national early infant diagnosis program during 2012 and 2013 were collected and assessed for HIV drug resistance. Pol-RT (reverse transcriptase) region was amplified, sequenced and analyzed for the presence of drug resistance mutations (DRMs). RESULTS: Overall, 121 of 201 (60.2%) newly diagnosed children had detectable DRMs. Among the 131 of 201 (65.2%) children with reported exposure to maternal and/or infant antiretrovirals (ARVs), DRMs were detected in 99 children (75.6%). Importantly, in 41 of 201 children for whom no exposure to ARVs was reported, DRMs were detected in 11 children (26.8%). For 29 children, no data on ARV exposure were available. For the 121 of 201 children with DRMs, 99 of 121 (81.8%) had only nonnucleoside reverse transcriptase inhibitor DRMs detected but 21 of 121 (17.3%) had both nonnucleoside reverse transcriptase inhibitor and nucleoside reverse transcriptase inhibitor (NRTI) DRMs. Among breast-fed children, drug resistance was more frequent when mothers were on antiretroviral therapy (ART), 61 of 75 (81.3%) versus 14 of 39 (35.9%) when mothers were not on ART (P < 0.001). Nucleoside reverse transcriptase inhibitor resistance was more common when mothers were on ART. CONCLUSIONS: Scale-up and improvement of PMTCT strategies resulted in a global decrease of pediatric HIV infections, but our study shows high rates of drug resistance in infants for whom prevention failed.

We report 11 cases of Meckel's diverticulum in children admitted to the department of Paediatrics Surgery of Lomé (Togo). None of the cases was identified before surgery. A systematic search during appendectomy identified 3 cases. It was fortuitously discovered four times, and due to complications in four cases. There was one complication related death. Segmental intestinal resection was the only technique used.
