[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.

[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.

[Pernicious anemia: diagnosis and course in Burkina Faso]. / Maladie de Biermer : aspects diagnostiques et évolutifs au Burkina Faso.

Pernicious anemia (also known as Biermer disease or anemia, Addison or Addisonian anemia, and Addison-Biermer anemia) is an autoimmune atrophic gastritis responsible for vitamin B12 malabsorption due to a deficiency of intrinsic factor. We report eight cases of pernicious anemia in Burkina Faso, collected over a 44-month period. The three criteria for diagnosis of pernicious anemia were: vitamin B12 deficiency, gastric disease (gastric histology) with presence of anti-intrinsic factor, and/or anti-gastric parietal cell antibodies in serum. All patients had anemia, with a mean hemoglobin level of 8.75 g/100 mL. The average mean corpuscular volume (MCV) was 122.1 fL the average mean corpuscular hemoglobin (MCH) 39.3 pg, the mean reticulocyte count 12.069 10(9)/L reticulocytes, and the mean rate of megaloblast marrow cells 17.2%. The serum vitamin B12 level ranged from 35 to 71 pmol/L. Antibodies against intrinsic factor were found in all eight patients. All ABO blood groups were present with a predominance (4 cases) of group O. Endoscopy found a normal fundic mucosa in three patients. Histology showed gastric atrophy and intestinal metaplasia for six patients (85.7%). Under B12 vitamin therapy, the course was favorable in all patients; seven patients also had 10 days of iron therapy. We recommend a gastric biopsy even in the absence of macroscopic gastric lesions on the upper gastrointestinal endoscopy.

[Semiological features and risk factors associated with osteoarthritis of the hip in Ouagadougou (Burkina Faso)]. / Caractéristiques sémiologiques et facteurs de risque associés à la coxarthrose à Ouagadougou (Burkina Faso).

OBJECTIVE: To study the epidemiological and clinical aspects of osteoarthritis (OA) of the hip in Ouagadougou, as well as its risk factors. PATIENTS AND METHODS: This retrospective study covered cases treated over a 3-year period (February 2006 through January 2009) in the internal medicine department of the Yalgado Ouedraogo Teaching Hospital of Ouagadougou (Burkina Faso) and the surgery department of the private hospital Notre-Dame-de la Paix of Ouagadougou. All patients included had OA of the hip that met the Kellgren and Lawrence criteria. RESULTS: There were 46 patients who met the study criteria, but only 40 files could be used. The patients' mean age was 46.4 years ± 15.2 years (range 25-80 years; 10 patients were older than 56 years). Men accounted for more than half (n=23, 57.5%). The mean duration of disease was 6.2 years ± 4.5 years (range: 1-19 years). The right hip alone was concerned in 20 patients (50%), the left hip in 16 (40%), and the OA was bilateral in four (10%). Seventeen patients had sickle cell disease (42.5%), 11 SC and 6 SS. The risk factors included necrosis of the femoral head in 19 cases (59.37%), hip dysplasia in 6 (18.74%), hip trauma in 3 (9.37%), inflammatory arthropathy in 3 more (9.37%), and epiphysitis in one (3.13%). The OA of the hip was primary in 8 cases (20%). Three patients were at stage 1, 9 at stage 2, 15 at stage 3, and 13 at stage 4 according to the Arlet-Ficat classification. CONCLUSION: OA of the hip arises in a young population and is dominated by secondary OA. The dominant risk factor was aseptic necrosis of the femoral head associated with sickle cell disease. In view of the small number of patients with primary OA, no definitive conclusions can be drawn about it.

[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.

[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.

[Prevalence and risk factors associated with infection by human immunodeficiency virus, hepatitis B virus, syphilis and bacillary pulmonary tuberculosis in prisons in Burkina Faso]. / Prévalences et facteurs associés aux infections a Virus de l'Immunodéficience Humaine et virus de l'épatite B, a la syphilis et a la tuberculose pulmonaire bacillifère en milieu carcéral au Burkina Faso.

This purpose of this study was to determine prevalences and risk factors associated with infection by human immunodeficiency virus, hepatitis B Virus, syphilis and bacillary pulmonary tuberculosis in prisons in Burkina Faso. From February 20 to March 20, 2009, 300 prisoners over 18 years of age held in Ouagadougou were selected to take part in this descriptive and analytical cross-sectional study. Sociodemographic data, confinement information (number, motive and prison time), medical history, substance addiction (alcohol, tobacco, drug), and the other risk behaviors (sexual relations, type of partners, sharing of toiletries or razor) were compiled for each prisoner. Serological tests were performed to detect anti-HIV antibodies, Hbs antigen, and anti-treponema antibody. In prisoners presenting signs of tuberculosis, BAAR detection was performed by direct examination of sputum. Men represented 95% of the study population. Median age was of 30.1 +/- 8.9 years (range, 18 and 63). The prevalences of HIV infection, Hbs antigen and positive syphilitic serology were 5%, 27.3% and 5.7% respectively. Four prisoners (1.3%) had bacillary pulmonary tuberculosis. Two prisoners reported homosexual intercourse and 44 reported drug abuse. Sharing of toiletries and razor blades was reported by 18.7% and 20% of the prisoners respectively. Immediate measures are needed reduce the spread of these infections in prisons in Africa.

[Management of the diabetic foot, apropos of 42 cases at the Ougadougou University Hospital Center]. / Prise en charge du pied diabétique (à propos de 42 cas au CHU de Ouagadougou).

Feet lesions are the most important cause of diabetic's consultation in general surgery. A retrospective study was conducted in Ouagadougou National Teaching Hospital, in order to analyse epidemiology, clinic, and evolutive aspects of this affection. In the same period, 222 cases of diabetes mellitus were admitted in general surgery and internal medicine. We noticed 42 cases of feet lesions. The mean age of patients was 53 years. Anterior knowledge of diabetes has not been a factor of early consultation. Consultation mean delay was a month. In 28 cases, feet lesions were 4 or 5 Wagner grade. The role of ischemia and neuropathy have not been evaluated, but sepsis was highly determinant factor. Insulin has been used in 83.3% of cases. Amputation concerned 19 patients. Mean length of hospital stay was 16.6 days and mortality rate was 38.1%. Prevention of complications can be much more effective if it is applied as a part of global approach to diabetes mellitus management.
