ABSTRACT
OBJECTIVES: A risk score for long-term prediction of chronic kidney disease (CKD) in people living with HIV (PLHIV) has been developed using data from the D:A:D cohort. We assessed the performance of the D:A:D risk score in a cohort of PLHIV in West Africa. METHODS: Data from PLHIV starting antiretroviral treatment in four clinics in Burkina Faso, Côte d'Ivoire and Togo participating in the IeDEA West Africa collaboration were analysed. CKD was defined as two consecutive estimated glomerular filtration rates (eGFRs) of ≤ 60 mL/min/1.73 m2 . The D:A:D score (short version) was calculated using age, gender, nadir CD4 and baseline eGFR and was categorized into low, medium, and high-risk groups. RESULTS: In 14 930 participants (70% female, median age = 38 years; median nadir CD4 count = 183 cells/µL) followed for a median duration of 5.7 years, 660 (4.4%) progressed to CKD, with an incidence [95% confidence interval (CI)] of 7.8 (7.2-8.4) per 1000 person-years (PY). CKD incidence rates were 2.4 (2.0-2.8), 8.1 (6.8-9.6) and, 30.9 (28.0-34.1) per 1000 PY in the low-, medium- and high-risk groups, respectively. In the high-risk group, 14.7% (95% CI: 13.3; 16.3) had progressed to CKD at 5 years. Discrimination was good [C-statistics = 0.81 (0.79-0.83)]. In all, 79.4% of people who progressed to CKD were classified in the medium- to high-risk group at baseline (sensitivity) and 66.5% of people classified in the low risk group at baseline did not progress to CKD (specificity). CONCLUSIONS: These findings confirm the validity of the D:A:D score in identifying individuals at risk of developing CKD who could benefit from enhanced kidney monitoring in West African HIV clinics.

We describe the characteristics of patients infected with HIV-1 as second-line antiretroviral therapy, with persisting low-level viremia. This was a descriptive retrospective study, conducted from January 1, 2010 to December 31, 2016, from the Cohort of the Infectious Diseases Department of Bobo-Dioulasso University Hospital. Patients infected with HIV-1, a second line of stable ARV treatment, with ≥95% compliance for at least 12 months, asymptomatic with CVp between 50 and 1000 copies/ml in two consecutive samplings at least 3 months apart. Out of 244 patients in second-line therapy, 79 met our inclusion criteria. The mean age of the patients was 42±10.2 years. Women (35.8 years) were younger than men (43.8 years) (p=0.001). Most were married (48.1%), 23.5% of whom were polygamous. The majority of patients (38/79) in the study had a CD4 count of <200 cells/ mm3. The median duration of ARV therapy since the beginning of the therapeutic history has been 4.8 (2.5-11 years). CVp greater than 10,000 copies/ml at the start of second-line therapy (p=0.003) and TDF+FTC + DRV + RTV combination (p=0.001) were associated with persistent low viremia. A genotypic resistance test is needed for these patients in order to better adapt the ARV treatment.
Nous décrivons les caractéristiques des patients infectés par le VIH-1 en deuxième ligne de traitement antirétroviral, avec une virémie persistante de bas niveau. Il s'agissait d'une étude rétrospective à visée descriptive, menée du 1er janvier 2010 au 31 décembre 2016, à partir de la cohorte du service des maladies infectieuses du CHU de Bobo-Dioulasso. Ont été inclus les patients infectés par le VIH-1, en deuxième ligne de traitement ARV stable, ayant une observance ≥ 95 % depuis au moins 12 mois, asymptomatiques, avec une charge virale plasmatique comprise entre 50 et 1 000 copies/ml sur deux prélèvements consécutifs à au moins 3 mois d'intervalle. Sur 244 patients en deuxième ligne de traitement antirétroviral, 79 répondaient à nos critères d'inclusion. L'âge moyen des patients était de 42 ± 10,2 ans. Les femmes (35,8 ans) étaient moins âgées que les hommes (43,8 ans) (p = 0,001). La plupart des patients étaient mariés (48,1 %), parmis lesquels certains vivaient dans des régimes polygames (23,5 %). La majorité des patients (38/79) de l'étude avaient un taux de CD4 ≤ 200 cellules/mm3. La durée médiane du traitement ARV depuis le début de l'histoire thérapeutique était de 4,8 ans (2,5- 11 ans). La charge virale plasmatique supérieure à 10 000 copies/ml au début du traitement (p = 0,003), et la combinaison TDF+FTC+DRV+RTV (p = 0,001) étaient associées à la virémie persistante de bas niveau. La réalisation d'un test génotypique de résistance s'impose pour ces patients afin de mieux adapter le traitement antirétroviral.

Highly active antiretroviral therapy (HAART) has reduced morbidity and mortality of HIV but has led to an increasing metabolic cardiovascular risk. A cross-sectional study was conducted from May to September 2011 in Day Care Hospital for HIV-Patients of Bobo-Dioulasso. We included in this study 400 patients infected by HIVon antiretroviral therapy ≥ 6 months selected by a random draw. Metabolic syndrome was assessed according to the definitions of the IDF and ATP-III. The high risk of cardiovascular disease in 10 years was defined by a Framingham score ≥ 20%. The average age of our patients was 41.4 years [20-76]. 17% received an IP. The average duration of PI exposure was 35.5 months and 50.1 months for NNRTI. The prevalence of diabetes was 1.3% (95% CI: 0.5-3) and that of hypertension of 12.0 % (95% CI: 9.3-16). The prevalence of metabolic syndrome according to IDF was 10% (95% CI: 7.3-13.5) and the metabolic syndrome according to ATP-III 12.3% (95% CI: 9.3-16). The body mass index was higher (BMI 25.2 vs. 22.5 kg/m(2), p <10(-3) with ATPIII and BMI 26.6 vs. 22.4 kg/m(2), p <10(-3) with IDF), and duration exposure to ARVs longer in patients with metabolic syndrome regardless of the definition used (58.6 months vs 27.9 months). High cardiovascular risk was present in 1.8% (95% CI: 0.8 to 3.7) of our patients, all male more than half (n=4/7) of them were smoking. The choice of antiretroviral therapy must take into account its potential long-term toxicity. It should also strengthen supervision.

OBJECTIVE: The authors had for aim to assess the prevalence of hepatitis B co-infection in a cohort of HIV-infected patients, routinely followed-up at the Day Care Unit of the Bobo Dioulasso Sanou Souro University Hospital, Burkina Faso. PATIENTS AND METHODS: The Elisa technique was used to dose HBs antigen (AgHBs), antibodies anti-HBs and anti-HBc in all the patients followed by the biological laboratory, from October to December 2008. RESULTS: The AgHBs prevalence was 12.7% [CI at 95%: 10.7-15.0%] and men were slightly more likely to be positive for AgHBs than women (16.5% [12.0-21.9%] versus 11.6% [9.4-14.1%]; P=0.047); 83.3% of the patients [80.8-85.6%] were positive for hepatitis B core antibody, and 32.6% [29.7-35.6%] for hepatitis B surface antibody; 29.9% of the patients [27.1-32.8%] had a complete profile of former hepatitis B infection, 41.3% [38.2-44.4%] expressed core antibodies only; 13.8% [11.7-16.0%] had a negative serological test, and 2.3% [1.5-3.4%] presented a vaccinal immunity. CONCLUSION: These results stress the usefulness of screening for hepatitis B in all HIV-infected patients, along with the initial biological tests. This would help adapt HIV treatment to co-infected patients and to build an expanded program of vaccination for non-immune patients.

OBJECTIVE: Vaccination against Haemophilus influenzae type b was introduced in Burkina Faso on 1st January 2006. This study thus sought to determine the impact of the first 30 months of vaccination on admissions for Hib meningitis in the department of pediatrics at the Sourô-Sanou University Hospital in Bobo Dioulasso. METHODS AND PATIENTS: Retrospective study of children aged zero to 14 years hospitalized from 1st January 2004 to 30th June 2008 for acute bacterial meningitis (laboratory-confirmed). RESULTS: During the study period, 416 children were admitted for acute bacterial meningitis. The bacterium isolated was identified in 386 cases and unidentified in 30 cases. Hib meningitis accounted for 42.3 % of the cases of identified bacterial meningitis before the introduction of the vaccine (2004 to 2005). This rate declined to 11.8 % for the first 30 months of vaccination (p < 0.001). No cases of Hib meningitis have been reported in the first half of 2008. CONCLUSION: Admissions for Hib meningitis in the Department of Pediatrics have practically disappeared two years after the introduction of the Hib vaccine into Burkina Faso's expanded program on immunization.
