[Etiological and evolving profile of renal disability of children in hospital in Togo]. / Profil étiologique et évolutif de l'insuffisance rénale de l'enfant en milieu hospitalier au Togo.

OBJECTIVE: To determine the etiological and evolutionary profile of renal failure of chidren in Togo. METHODS: This is a cross-sectional study over the period of 12 months (2016-2017) including children aged 1 to 18 years hospitalized in the pediatric ward of Sylvanus Olympio university teaching hospital of Lome (Togo) for renal failure. RESULTS: Of 2374 patients hospitalized in our unit, 58 (2.4%) had renal failure. The mean age was 8.17±4 years with a sex ratio of 1.32. The average consultation time was 11.9 days. The mean duration of hospitalization was 12.7±7.7 days. Thirty-seven patients (63.8%) were referred from a peripheral center. Thirty-seven children out of 58 (63.1%) were oligoanuric. Renal failure was acute in 94.8% and chronic in 5.2%. Anemia was found in 84.4% of children. The main etiologies found were severe malaria (63.8%), glomerulonephritis (10.3%) and nephrotic syndrome (10.3%). Thirteen children (22.4%) benefited from dialysis sessions. The evolution was favorable in 79.3% of the cases. CONCLUSION: The renal failure of child is relatively common in our daily practice. The low socio-economic level and the lack of adapted equipment make the care difficult.

Therapeutic efficacy trial of artemisinin-based combination therapy for the treatment of uncomplicated malaria and investigation of mutations in k13 propeller domain in Togo, 2012-2013.

BACKGROUND: Since 2005, the Togo National Malaria Control Programme has recommended two different formulations of artemisinin-based combination therapy (ACT), artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL), for the treatment of uncomplicated malaria. Regular efficacy monitoring of these two combinations is conducted every 2 or 3 years. This paper reports the latest efficacy assessment results and the investigation of mutations in the k13 propeller domain. METHODS: The study was conducted in 2012-2013 on three sentinel sites of Togo (Lomé, Sokodé and Niamtougou). Children aged 6-59 months, who were symptomatically infected with Plasmodium falciparum, were treated with either AL (Coartem(®), Novartis Pharma, Switzerland) or ASAQ (Co-Arsucam(®), Sanofi Aventis, France). The WHO standard protocol for anti-malarial treatment evaluation was used. The primary end-point was 28-day adequate clinical and parasitological response (ACPR), corrected to exclude reinfection using polymerase-chain reaction (PCR) genotyping. RESULTS: A total of 523 children were included in the study. PCR-corrected ACPR was 96.3-100 % for ASAQ and 97-100 % for AL across the three study sites. Adverse events were negligible: 0-4.8 % across all sites, for both artemisinin-based combinations. Upon investigation of mutations in the k13 propeller domain, only 9 (1.8 %) mutations were reported, three in each site. All mutant parasites were cleared before day 3. All day 3 positive patients were infected with k13 wild type parasites. CONCLUSIONS: The efficacy of AL and ASAQ remains high in Togo, and both drugs are well tolerated. ASAQ and AL would be recommended for the treatment of uncomplicated malaria in Togo.
