Obesity and Metabolic Syndrome in a Burkina Faso Urban Area: Prevalence,Associated Factors and Comorbidities

Background: The prevalence of obesity and metabolic syndrome is not just a problem of the developed countries but is also with a growing trend in developing countries, especially in urban areas. We aimed to estimate the prevalence of obesity and metabolic syndrome in the urban population living in Ouagadougou, Burkina Faso, and to investigate the factors and comorbidities associated with them. Methods: Data were collected in two rounds (in March and December 2011) from two different neighbourhoods (peripheral and central) of Ouagadougou. We included all over 20 year old volunteers’ subjects (excluding pregnant women). All characteristics were collected during face-to-face interviews. We used international standards to define obesity, hypertension and metabolic syndrome. The statistical analysis used chi-square (chi 2) tests and odds ratio with 95% confidence interval. Results: 632 subjects with a mean age of 41.3 ± 6.8 years [20-75 years] and sex ratio (men/women) of 0.9were included in this survey. Overall crude prevalence of overweight, obesity and metabolic syndrome were respectively 30.5%, 22% and 7%. Compared with normal weight participants, obese individuals had more hypertension, diabetes or impaired fasting glucose (p=0.000), and they were more likely to be older, women, employed and living in the central neighbourhood. Obesity was found in 81.8% of subjects with metabolic syndrome. On bivariate analysis, those with the metabolic syndrome were female, older, and obese Conclusion: The prevalence of obesity and metabolic syndrome in urban Burkina Faso is high. There is a need to pay closer attention to combating these health disorders. An important place must be reserved for the prevention and the fight against obesity by appropriate lifestyle.

Features of Metabolic Syndrome and Its Associated Factors during Highly Active Antiretroviral Therapy in Ouagadougou (Burkina Faso)

Background: To study the features of metabolic syndrome (MS) and its associated factors during highly active antiretroviral therapy (HAART), in Ouagadougou. Methods: It was a cross-sectional study from March to November 2011 in Yalgado Ouédraogo hospital. A nonprobability sample of adults receiving antiretroviral drugs for at least 6 months was studied. Pregnancy, ascites, or abdominal mass were noninclusion criteria. Metabolic syndrome met the criteria of International Diabetes Federation 2005. Results: The authors studied 300 patients. Metabolic syndrome was diagnosed in 54 (18%) patients: mean age 44.8 ± 7.4 years, sex ratio 0.17, and mean duration of HAART 71 ± 30.9 months. The current anomaly of MS was low high-density lipoprotein (HDL)-cholesterol in 37 patients (68.5%), and the common profile of MS was high waist circumference + low HDL-cholesterol + abnormal blood pressure (29.6%). Associated factors were protease inhibitor regimens (P = .000), female gender (P = .004), age > 42 years (P = .001), and lipodystrophy (P = .01). Conclusion: Cardiovascular risks should be regarded during the care of HIV-infected patients.

The bacterial microflora of diabetic foot infection and factors determining its spectrum in 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 bacterias 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.

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.

Pathologies rhumatologiques et hémoglobinopathies à Ouagadougou (Burkina Faso)

The purpose of this study is the prevalence of the rheumatologic complications in the sickle cell disease and the associations between haemoglobinopathies and rheumatologic affections. It is a retrospective study from 29 February 2006 to 28 March 2008 conducted in the Internal Department of the University Hospital Yalgado-Ouédraogo. All patients received in the period of study and having an electrophoresis of haemoglobin realized in alkaline pH were included. These patients came from hematologic consultation. Two hundred and seventy-seven patients out of 1451 were included: 142 patients (51.30%) had haemoglobinopathies, including 21 (7.60%) with composite sickle cell disease SC and 17 patients (6.13%) had aseptic necrosis of the femoral head including 7 with haemoglobin SC. The other rheumatologic affections did not have a semiological particularity related to the type of haemoglobin. The prevalence of patients who have haemoglobinopathies is important in rheumatologic practice. The sickle cell disease is strongly associated to osteonecrosis.

Frequency, Risk Factors and Clinical Forms of Neuropathies in Diabetics in Hospitals in Burkina Faso

Introduction: Diabetic neuropathy is one of the most common chronic complications of diabetes. Most of the studies on the subject in the sub region, particularly in Burkina Faso, dealt it with the study of the complications of diabetes, or one of its components. Our study was designed to study in particular in all its aspects, by searching for its peculiarities in our context, for improvement of its support. Methodology: This is a cross-sectional descriptive study carried out in 150 diabetic patients aged at least 15 years followed in the Department of Internal Medicine at Yalgado Ouedraogo University Teaching Hospital. All patients included had agreed to participate in our survey after informed consent. We collected the data during the period from 2015 November to 2016 June. Each patient was evaluated by the DN4 questionnaire and clinically by a neurological examination. We determinated the frequency, the sociodemographic, clinical and therapeutic characteristics of diabetes neuropathy and its related factors. Results: The frequency of diabetic neuropathy was 80.7%. Peripheral neuropathies were seen in 81.8% of cases and autonomic neuropathies in 72.7% of cases. Autonomic neuropathy was dominated by the DAN (59.1%), and erectile dysfunction (44%). There was a high comorbidity with physical inactivity (66.9%), obesity (49.4%) and hypertension (38.8%). There were poorly controlled patients in 38.8%. A link was found between T2DM and neuropathy (p = 0.014). Painful diabetes was related to the quality of glycemic control (p = 0.007), and hypertension (p = 0.021). A link was also found between tobacco consumption (p < 0.001), male (p < 0.001), and urogenital autonomic neuropathy. Conclusion: Diabetic neuropathies are very common in our context and could be a haunting to the practitioner with the progression of diabetes and its corollary of degenerative complications. There was a significant association between Type 2 Diabetes mellitus and the presence of peripheral diabetic neuropathy.

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.
