[Sexuality and risk for sexual transmission of HIV among serodiscordant couples in Ouagadougou, Burkina Faso]. / Sexualité et risque de transmission du VIH chez les couples sérodiscordants suivis à l'hôpital de jour du CHU de Ouagadougou (Burkina Faso).

This article is a contribution to improve the management of serodiscordant couples in Ouagadougou. The aim of the study was to explore sexuality and the risk for sexual transmission of HIV among serodiscordant couples followed-up in CHU-YO. The study consisted of a descriptive cross-sectional study conducted over 6 months, from 1 January 2010 to 30 June 2010. A total of 80 heterosexual serodiscordant couples participated. Women were infected with HIV in most cases (75%). The mean age was 37.5 years for HIV partners and 40 years for seronegatives. Men were significantly older than women (p = 0.01). The couples weremarried (83.7%) or cohabiting (16.3%). The average of serodiscordance duration was 4 years. Seventy-four couples (92.5%) engaged in sexual intercourses, mostly vaginal intercourses. Both partners were satisfied only in 9 couples (12.2%). Although most couples (97.5%) knew the use of condoms for HIV prevention, 59.5% did not use it consistently, particularly when women were the seropositive partners (p = 0.01). The lack of privacy (37.5%) and desire of childbearing (26.25%) were the main reasons for not consistently using condoms among couples. Sexual dysfunction was a concern with 97.5% of the couples. The decrease in libido was most common (37.2%). Sexual intercourses with an outside partner were reported in 20 couples (25%), mostly regarding men (p = 0.03). Specific management could improve the quality of sexual life for couples in the light of the difficulties they face and reduce the risk for HIV transmission to negative partners.

[Metabolic disorders and cardiovascular risk factors observed in patients infected by the HIV with antiretroviral therapy in Burkina Faso]. / Troubles métaboliques et facteurs de risques cardiovasculaires chez les patients infectés par le VIH sous antirétroviraux au Burkina-Faso.

The purpose of this descriptive transverse study is to describe metabolic disorders and cardiovascular risk factors in HIV-infected patients undergoing antiretroviral therapy in the day-care unit of the University Hospital of Ouagadougou, Burkina-Faso. A total of 100 patients (Burkinavi cohort) undergoing antiretroviral therapy with a minimum of 42-months of follow-up (October 2005 to Mars 2009) were included. There were 77 females and 33 males with a mean age of 37 years. Most patients, i.e., 95%, were positive for HIV1. Mean body mass index was 22 kg/m2. Mean CD4 count was 280/mm3. Viral load was undetectable in 66 of the 71 patients who underwent viral load testing. Retroviral therapy consisted of the TriomuneR combination (Stavudine + lamivudine + névirapine) at a fixed dose in 27 cases. Cardiovascular risk factors included family history of high arterial blood pressure in 5 patients, smoking in 4, and obesity in 8. During follow-up, seven patients presented hypertension. Metabolic disorders included hyperglycemia (4%), hypertriglyceridemia (17%) and hypercholesterolemia (14%). Lipodystrophia was noted for 6 patients. Despite the short follow-up period, metabolic disorders and cardiovascular risk factors were observed at our patients under antiretroviral therapy.

[About 98 cases of dengue hospitalized in a private clinic of Ouagadougou: epidemiology, diagnostic and evolution]. / À propos de 98 cas de dengue hospitalisés dans une clinique privée de Ouagadougou : aspects épidémiologiques, diagnostiques et évolutifs.

Extremely widespread, the dengue is a reemerging infectious disease. In Burkina Faso, dengue is a reality that was little known. The aim of this study was to study epidemiology, diagnostic and outcomes of dengue patients in Ouagadougou. A retrospective study covered a period of two years, from 1 January 2013 to 31 December 2014 in a private clinic in Ouagadougou. Patients included in the study were hospitalized for fever and painful syndrome with a positive test to the dengue non-structural antigen 1 (NS1 Ag). Ninety-eight cases of dengue on 343 suspected cases were registered. The average age of patients was 35.9 years. The sex-ratio (M/F) was 1.18. According to the professional activity, there was a predominance of civil servants (35.7%). The pain syndrome was found in 93.9% of patients. Leukopenia (73.5%), neutropenia (56.1%) and severe thrombocytopenia (57.1%) were the predominant hematological disturbances. Of the patients, 18.4% had hemorrhagic dengue and 11.2%, a dengue shock syndrome. Four patients died. The use of non-steroidal antiinflammatory drugs was associated with the severity of the infection (p=0.04). Dengue fever occurs in our context and constitutes a risk of mortality. The diagnosis of dengue should be performed systematically in front of a painful and febrile syndrome. The vector control is the best way of prevention against dengue pending the development of a vaccine.

Prevalence of non-adherence to highly active antiretroviral therapy and its related clinical and therapeutic factors in Ouagadougou (Burkina Faso).

Introduction : Non-adherence to highly active antiretroviral therapy is deleterious in HIV/AIDS programs. This study contributes to the identification of its frequency and of the clinical and therapeutic factors that determine it. Material and methods : This cross-sectional study took place from December 15, 2013, to February 18, 2014, at the Saint Camille health care center and the Pietro Annigoni biomolecular research center in Ouagadougou. It includes adults who had been receiving antiretroviral therapy for at least three months and agreed to participate. The Chi-square test or Fisher's test was used to compare proportions in the univariate analysis. A logistic regression model was applied for the multivariate analysis. P values less than 0.05 were considered significant. RESULTS: The study included 152 patients. Their mean age was 40.7±7.8 years, and the sex-ratio 0.3. The frequency of non-adherence to antiretroviral therapy was 38.2%. In the univariate analysis, laboratory and clinical factors associated with non-adherence were severe immune depression (P=0.03), opportunistic infections (P=0.001), and lack of clinical improvement (P=0.001), while the therapeutic factors associated with it were inadequate knowledge (P=0.001), side effects (P=0.003), and using the treatment secretly (P=0.001). In the multivariate analysis, opportunistic infections (OR=13.51, 95% CI 3.15-58.82, P=0.000), lack of clinical improvement (OR=4.16, 95% CI 1.06-16.32, P=0.04), inadequate knowledge (OR=16.12, 95% CI 1.67-166.66, P=0.01), and secret treatment use (OR=11.36, 95% CI 3.18-40.00, P=0.000) remained associated with non-adherence. CONCLUSION: The study underlines the need to improve strategies for the prescription of this therapy and for reinforcing patients' education and support.

[Antibiotic susceptibility of bacteria isolated from diabetic foot infections and prospects for empiric antibiotic therapy in Ouagadougou (Burkina Faso)]. / Étude de la sensibilité aux antibiotiques des bactéries isolées lors de l'infection du pied diabétique et perspectives d'antibiothérapie à Ouagadougou (Burkina Faso).

INTRODUCTION: The aim of this study was to study the antibiotic susceptibility of bacteria isolated from diabetic foot infections to help improve empiric antibiotic prescription in Ouagadougou, where bacteriological testing is rarely possible. METHOD: This cross-sectional study took place from July 1, 2011, to June 30, 2012, in the departments of internal medicine and general and gastrointestinal surgery in the Yalgado Ouédraogo teaching hospital. Bacteria were isolated from diabetic foot infections and their antibiotic sensitivity was tested by the qualitative method (Kirby-Bauer). RESULTS: The study included 64 patients, with a median age of 57 years (interquartile range: 48-75) and a M/F sex ratio of 1.37. Among them, 39 had received antibiotics before hospitalization. Among the 71 samples, 62 cultures (87%) were positive: 53 for a single microbe (85%) and 9 for two microbes (15%). Microorganisms were mainly aerobic and anaerobic Gram-positive cocci (76%), including Staphylococcus aureus (SA) (33%) and Streptococcus spp (18%). These Gram-positive cocci were highly sensitive to amoxicillin-clavulanic acid and oxacillin. No methicillin-resistant SA (MRSA) were isolated. Enterobacteriaceae (24 %) were highly susceptible to imipenem and ticarcillin, but not to ceftriaxone or ciprofloxacin. No extended-spectrum beta-lactamase Enterobacteriaceae (ESBL) were isolated. Pseudomonas aeruginosa was highly susceptible to ciprofloxacin and imipenem. CONCLUSION: Despite our study's limitations, our findings show that most diabetic foot infections can be successfully treated with standard antibiotics.

[Characteristics of the patients "lost to follow-up" and determining factors of loss to follow-up to patients living with HIV at Ouagadougou, Burkina Faso]. / Caractéristiques des patients "perdus de vue" et facteurs déterminants de la perte de vue au cours du suivi des patients infectés par le VIH à Ouagadougou, Burkina Faso.

The objective of this study is to describe the characteristics of the patients "lost to follow-up" and determining factors of lost to follow-up at the patients infected by HIV. This is a descriptive and analytical retrospective study made on patients with or not by HAART, registered in the Day hospital of Ouagadougou. Of 5118 adult patients studied, 402 (7.9%) lost to follow-up. Among these patients, 340 (84.5%) had an unknown vital status, 28 (7%) were alive and 34 (8.5%) died. Mean age was 37.5 years. After active research, 16 from 21 patients under HAART were in treatment interruption. The main factors associated with the loss of follow-up were: no schooling (p=0,008), residing outside the capital (p=0,002) and being infected with HIV2 (p< 10(-3)). The phenomenon of loss of follow-up is important and concerned mainly not informed patients.

[The bacterial microflora of diabetic foot infection and factors determining its spectrum in Ouagadougou (Burkina Faso)]. / Écologie bactérienne et facteurs déterminant le profil bactériologique du pied diabétique infecté à Ouagadougou (Burkina Faso).

The aim of the study was to describe the bacterial microflora of diabetic foot infection and to identify the factors which determine the bacterial spectrum in order to increase empiric antibiotic prescription in Ouagadougou. The study was a cross-sectional one, carried from July 1st, 2011 to June 30, 2012 in the departments of internal medicine and general and digestive surgery in Yalgado Ouédraogo teaching hospital. Samples for bacteriological tests consisted of aspiration of pus through the healthy skin, curettage and swab of the base of the ulceration or tissue biopsy from foot lesions. The bacteria's sensitivity to antibiotics has been tested by the qualitative method (Kirby-Bauer). The frequency of diabetic foot infection was 14.45% and the monthly incidence 5.33. The mean age of patients was 56 years and the sex ratio 1.37. Foot ulcerations were chronic in 33 (51.56%), necrotic in 51 (79.69%) and associated with osteitis in 40 (62.5%) patients. Infection was grade 3 in 70.3% cases. Thirty-nine patients had received antibiotics before hospital admission. Among the 71 samples, 62 (87.32%) cultures were positive: 53 (85.48%) monomicrobial and 9 (14.52%) bimicrobial. Aerobic Gram-positive cocci (76%) were the most frequent from ulcerations: Staphylococcus aureus (32.39%), Streptococcus sp (18.30%). Negative coagulase staphylococci have been found in 23.94% cases. Aerobic gram-negative bacilli have been isolated from 24% ulcerations. No factor was associated with the type of bacteria. Gram-positive pathogen cocci showed a high sensitivity to amoxicillin-clavulanic acid and oxacillin. No methicillin-resistant Staphylococcus aureus (MRSA) or extended-spectrum beta lactamase Enterobacteriaceae (ESBL) have been isolated. A better design is necessary to a clarification of bacterial flora in diabetic foot infections. Prevention of bacterial resistance is also needed.

[Arterial hypertension and diabetes in Ouagadougou (Burkina Faso)]. / Hypertension artérielle et diabète à Ouagadougou (Burkina Faso).

We report a 3 year survey concerning diabetes associated with hypertension in 260 diabetic patients at Ouagadougou. This association has been found in 29% of the cases. The patients were male subjects for 57% of them and seventy one more 50 years old. Other vascular risk factors have been observed: obesity (53%), smoking (15%), hyperuricemia (23%). Hypercholesterolemia and hypertriglyceridemia were observed respectively in 1% and 1.3% of the cases. Many complications arised during the survey: retinopathy in 51% of the patients, nephropathy for 35% and 12% with renal failure, macroangiopathy in 55% of the patients. The treatment was based on diuretics and calcic inhibitors. The results on the control of blood pressure were excellent but the high cost of this management is an important restrictive factor.

[Laboratory test features of newly diagnosed adult HIV-infected patients in Ouagadougou (Burkina Faso)]. / Profil biologique des patients nouvellement pris en charge pour une infection à VIH à Ouagadougou (Burkina Faso).

In a sub-Saharan African population of adults beginning care for HIV infection, we sought to describe some laboratory features and their correlation with disease progression. We retrospectively reviewed pretreatment laboratory records of recently diagnosed adults (Elisa test) beginning care at the Internal Medicine department of Yalgado Ouédraogo University Hospital between June 2009 and August 2010. The values have been classified according to WHO standards. During the study period, 177 patients were newly diagnosed as HIV-positive. Among them, 144 (81.4%) had CD4 counts below 350 cells/µL. The mean hemoglobin level was 10.3 ± 2.1 g/dL for women (n = 94) and 11.2 ± 2.8 g/dL for men (n = 67, p = 0.028), and 113 (71.1%) had anemia, 12 of them severe (7.5%). Anemia and lymphopenia were significantly correlated with a low CD4 count (p = 0.001 and 0.003 respectively). Six patients (3.4%) also had type 2 diabetes. Total cholesterol was normal in all patients, and 8 (10.4%) had hypertriglyceridemia. Hematopoietic, glycemic and lipid disorders seem relatively common in untreated black patients with HIV infection. A low CD4 count appears to predict hematopoietic cell deficits.

[Vitamin D-deficiency rickets: a case report from Burkina Faso]. / Le rachitisme carentiel: une observation au Burkina Faso.

Deficiency rickets results from a deficiency of vitamin D that is responsible for deficient calcium absorption, leading to failure of bone mineralization and cartilage bone growth, especially in children. We report the case of a 9-year-old girl who shows signs of rickets. Her family history, which includes similar malformations in several family members, led us to suggest vitamin D-resistant rickets, but all laboratory tests and response to treatment indicated deficiency rickets. Prophylaxis, at least for some very poor people, should be proposed for certain populations at risk, even in tropical zones.
