ABSTRACT
: Dengue is still a public health problem in tropical countries. This disease, which had almost disappeared in some areas of the world, has become re-emergent in certain parts of the world including Africa.The aim of this study is to determine the seroprevalence and evolution of Dengue virus (DENV) infection from 2020 to 2021 at the Hospital Saint Camille de Ouagadougou (HOSCO), Burkina Faso. Methodology: This was a descriptive analytical study of patients seen in general practice with febrile syndrome referred for serological diagnosis of Dengue at the HOSCO laboratory over a period of 2 years (January 1, 2020 December 31, 2021). The "Dengue Duo (AgNS1/IgM/IgG)" kit from SD Bioline was used for the rapid diagnosis through the detection of NS1 antigen and IgM/IgG antibodies in plasma. Data were analysed with SPSS version 20.0 software. Association between demographic data and prevalence of DENV infection was determined by Chisquare test and odds ratio (with 95% confidence interval). P value less than 0.05 was considered statistical significance. Results: A total of 2957 patients aged 0-94 years were referred for serological diagnosis of DENV infection at the HOSCO laboratory over the period 2020-2021, comprising 56.3% females and 43.7% males. The overall prevalence of acute DENV infection (NS1Ag positive) was 5.4% (159/2957), with 2.4% (41/1700) in 2020 and 9.4% (118/1257) in 2021 (OR=4.192, 95% CI=2.915-6.028, p<0.0001). The prevalence of acute DENV infection of 7.0% (91/1292) in the males was significantly higher than 4.1% (68/1665) in the females (OR=1.779, 95% CI=1.288-2.458, p=0.0005), and also significantly higher in age groups 20-29 years (7.6%), 10-19 years (6.9%) and 40-49 years (5.8%) than other age groups (X 2=14.928, p=0.0107). The overall prevalence of DENV IgM and IgG antibodies was 3.2% and 37.3% respectively. The prevalence of DENV IgG antibodies was significantly higher in males (44.0%) than females (32.1%) (OR=1.667, 95%CI=1.434-1.938, p<0.0001) and in age groups 30-39 (43.4%), 40-49 (44.0%) and >50 years (49.3%) than other age groups (X2=121.0, p<0.0001), indicating that past exposure to DENV infection is higher among males and older age groups. The peak of DENV infection was between October and November with 84.3% (134/159) of NS1Ag positivity occurring during this period. Conclusion: The present study reports a high prevalence of acute Dengue virus infection in patients from October to November. To eradicate Dengue which has become a tropical silent epidemic, interventions such as vector control, availability of and accessibility to diagnostic tests, and good therapeutic management are of great importance

Objectif : Etudier les complications aiguës métaboliques (CAM) du diabète sucré dans le Service de Réanimation Polyvalente (SRP) du Centre Hospitalier Universitaire Yalgado Ouédraogo (CHU-YO) au Burkina Faso.Patients et méthodes : Etude rétrospective sur une période de cinq ans (1erjanvier 2008 au 31 décembre 2012). La population d'étude était constituée des patients admis dans ledit service pour une CAM du diabète sucré. Résultats :Soixante-six patients ont été retenus pour l'étude.La fréquence d'admission pour des CAM de diabète était de 6,5% avec un âge moyen de 55 ± 17 ans et une prédominance masculine (sex-ratio=1 ,06). Les principaux motifs d'admission étaient lecoma grave (62,1%), détresse respiratoire (81,8%) et déshydratation (15,1%).La mauvaise observance thérapeutique était retrouvée dans 64,5%.L'acidocétose constituait 59,1% des CAM suivie de l'hypoglycémie (27,3%) et du syndrome d'hyperglycémie hyperosmolaire(SHH) (13,6%). L'hyperglycémie moyenne était de 26, 31 mmol/L et l'hypoglycémie moyenne de 1,3 ± 0,7 mmol/L. Une cétonurie (69,1%) et une glycosurie (67,8%) étaient observées. Les complications étaient associées à un âge avancé (p= 0.003).L'infection constituait le principal facteur de décompensation. La durée moyenne de séjour était 5,8 ± 5,6 jours.La mortalité globale (54,55%) était liée à la gravité du coma (p=0,007).Conclusion : Les CAM du diabète sucré sont relativement fréquentes dans le SRP du CHU-YO à Ouagadougou. Le taux de mortalité est élevé. Une prise en charge précoce et adaptée pourrait améliorer le pronostic vital

Background: The colostrum of HIV-infected mothers contains a high number of HIV copies and is considered highly infectious. Furthermore it contains large numbers of macro- phage and other mononuclear cells that are known to incorporate virus. While prevention protocols in Western countries suggest the interruption of breast feeding; at least for the first few months of life; this practice is not advisable in developing countries. Methodology: The aim of this study was to determine the HIV load and the concentrations of IL-18; IL-16; IL-12; TGF-beta1 and TGF-beta2 in the colostrum of HIV-infected mothers living in Burkina Faso. The women all received nevirapine prophylaxis during labour. Results: The viral load in the colostrum decreased rapidly during the first three days following delivery; while the concentration of IL-18 and IL-16 increased in the same period. IL-12; TGF-beta1 and TGF-beta2 did not show significant variations in the first three days after delivery. Conclusions: Since the viral load decreases in the colostrum of nevirapine-treated expectant mothers; our data suggest single dose nevirapine combined with interruption of early feeding may have potential as a way to reduce the risk of MTCT
