RESUMEN

BACKGROUND: Like many African countries, the issue of sex between men in Burkina Faso remains taboo and sometimes result in social exclusion. This population which is vulnerable to HIV/AIDS is unknown, due to lack of scientific researches. AIM: Our study aimed to characterize knowledge, attitudes and sexual practices and to estimate HIV seroprevalence among men having sex with men (MSM) living in Ouagadougou. METHODS: A cross-sectional study was conducted in order to describe and analyze MSM living in Ouagadougou. They were recruited by snowball sampling, aged at least 18 years, and accepted to participate at the study. Data were collected by qualified interviewers through administered questionnaire face to face. HIV test was systematically proposed. RESULTS: A total of 142 MSM were recruited during the study period. The sample was mostly composed of students or pupils (60.8%), single men (91%), with age range 18-30 years (96.5%). The HIV knowledge median score was 8/10. HIV seroprevalence was 8.9% (4.5-15.4). CONCLUSION: Our study confirms the vulnerability of MSM living in Ouagadougou about HIV/AIDS given the high rate of HIV seroprevalence. Targeted interventions for prevention, care and scientific research are challenges for the authorities to sustain the achievements of the national fight against HIV and AIDS.

RESUMEN

The aim of this survey was to assess the HIV risk practices of male prisoners and their access to prevention. This descriptive study took place at the House of Detention and Corrections in Ouagadougou from June through August 2012. In all, 165 prisoners (median age: 28 years, range: 18-65) were interviewed. A low proportion of the prisoners (16%) had accurate knowledge of the modes of HIV transmission. Before imprisonment, their sex lives featured multiple partners, occasional sex, and low condom use. Seven (4%) prisoners reported homosexual relations while in prison. The conditions of incarceration and the denial of homosexual practices at Ouagadougou aggravate prisoners' vulnerability to HIV/AIDS.

RESUMEN

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.

RESUMEN

OBJECTIVE: The goal of the study was to assess the activity of a multidisciplinary structure for HIV infected patients, two years after the opening of the day hospital. DESIGN: A retrospective observational study of the Bobo Dioulasso day-hospital was made using the ESOPE (Epiconcept, France) software. RESULTS: In 2002, 147 patients were followed in the Bobo Dioulasso university hospital, 27 (or 18.5 %) of whom were treated with antiretrovirals. Between 2005, opening of the day-hospital, and 2007, the total number of patients increased by 20 %. The number of patients on antiretrovirals rose from 47 to 70 % in the same time. The rate of patients with waved antiretroviral costs rose from 6 to 53 %. Three hundred and eighty-six patients died between 2002 and 2007. 1450 patients were lost to follow-up between 20002 and 2007. CONCLUSIONS: Two years after its opening, the Bobo Dioulasso day-hospital manages one of the largest HIV cohort in sub-Saharan Africa and has become a reference structure in Burkina Faso. The analysis of this cohort was an opportunity to identify issues concerning HIV patient treatment in 2009.

RESUMEN

Haematological anomalies are frequent during HIV infection, and can be the fact of virus and or bone marrow toxicity of antiretroviral drugs. In order to analyze the evolution of the haematological parameters during HAART this work was carried out in the internal medicine department of the national teaching hospital Yalgado-Ouédraogo in Ouagadougou. So 107 patients receiving for the first time HAART and followed regularly were retained. The immunological efficacy at the end of the first six months was 60, 75% with an average gain of 119 CD4/mm3. The haematological changes at the end of these first six months showed: --an anaemia in 51.4% of the cases at month 6 versus 80.3% at baseline (p=0.0001). The average rate of haemoglobin was 11.8 versus 11.2 g/dl at baseline in the AZT containing HAART regimen (p=0.014) and 12.2 versus 10.7 g/dl at baseline in the group without AZT (p=0.00006). --a neutropenia in 35.5% of the cases at month 6 versus 31.7% at baseline (p=0.6). The average rate of neutrophil was 1908/mm3 versus 2267.1/mm3 at baseline in the AZT containing HAART regimen and 2150.7/mm3 versus 2001.9/mm3 at baseline in the group without AZT These results show that the therapeutic efficacy measured on the immunological answer is accompanied by a reduction of haematological anomalies. They also suggest the necessity to evaluate the cotrimoxazole impact before deciding the interruption of AZT.

RESUMEN

In HIV/hepatitis C virus (HCV)-coinfected patients, it is recommended to repeat liver biopsy every 3 years when anti-HCV treatment is not indicated. We studied fibrosis progression in HIV/HCV-coinfected patients, who were not receiving anti-HCV treatment, on the basis of two successive liver biopsies. Thirty-two patients were retrospectively included. Twenty-six patients (79%) were on antiretroviral treatment at the first biopsy. The mean CD4 cell count was 470 +/- 283/mm(3). Three patients were staged F2 and the remainder F0/F1. The median interval between the two biopsies was 49 (24-80) months. At the second biopsy, the stage distribution was F0 0%, F1 41% (n = 13), F2 34% (n = 11), F3 19% (n = 6) and F4 6% (n = 2). The mean fibrosis progression rate (FPR) was 0.25 points/year. Nine patients (28%) were considered as rapid fibrosis progressors (progression by more than two points) and their FPR was 0.5 point/year; comparison of these subjects with the other 23 patients showed no relation between FPR and age, alcohol consumption, CD4+ cell count, HIV viral load, HCV genotype, aspartate aminotransferase or alanine aminotransferase. Analysis of the treatment received between the two liver biopsies did not find any correlation between liver FPR and a specific compound. Fifteen patients started anti-HCV therapy based on the second biopsy. Liver fibrosis in HIV/HCV-coinfected patients should be evaluated at least every 3 years, as nine of 32 (28%) of our patients progressed by at least two fibrosis points despite a high CD4+ cell count. The second biopsy showed that 15 patients (45%) qualified for anti-HCV therapy. Development of noninvasive methods of fibrosis evaluation should permit more frequent monitoring.

RESUMEN

INTRODUCTION: The diagnostic approach when confronted with a pseudo-tumoral lesion and fever is difficult since it evokes an infectious, rheumatismal inflammatory or even systemic disease. OBSERVATION: A 39 year-old Vietnamese man was hospitalised for polyarthralgia if the arm and fever (39 degrees C). He was treated with non-steroidal anti-inflammatories, which were only partially effective. Biological examinations revealed a severe inflammatory syndrome and cytolysis three-fold higher than normal. Since the infectious, rheumatismal and immunological explorations were negative and in view of the appearance of a pseudo-tumoral inflammatory lesion of the left arm concomitant to infiltration of the underlying muscle revealed on MRI, a muscle biopsy was performed showing eosinophilic fasciitis. Diagnosis of Shulman's syndrome was made and the affection rapidly improved with corticosteroids. COMMENTS: The presentation of our patient was atypical for several reasons: his Vietnamese origin, the initial fever peak at 39 degrees C, the unilateral involvement, the severe inflammatory syndrome, the initial absence of hypereosinophilia, the visceral involvement and notably myositis are all uncommon in Shulman's syndrome. Hence, it is important to rule out its differential diagnosis from local edematous scleroderma, which does not share the same prognosis.

RESUMEN

CHARACTERISTIC FEATURES: Piercing, an act that modifies the body, has progressed considerably in France over the last few years. The population involved has grown and become more diversified. Performed with a solid needle or a catheter, a wide variety of anatomic localizations are concerned, particularly the nose, ears, and navel. The shape of the "rings", generally made of surgical steel, niobium or titanium, varies greatly. Wound healing by epithelialisation can take up to several months. INFECTIOUS RISK: Between 10% and 20% of all piercings lead to a local infection. The most commonly found causal agests are Staphylococcus aureus, group A Streptococcus and Pseudomonas sp. These germs can cause severe life-threatening complications even in common localizations (earlobe). Viral transmission is another risk (hepatitis B, hepatitis C, hepatitis delta, HIV). A few cases of fatal fulminant hepatitis have been described immediately after piercing. SAFETY MEASURES: Generally performed under less than desirable sanitary conditions, safety measures are needed for piercing. Among professional "piercers", a certain number have emphasized the need for providing their clients with safer services. The prevention of infection risk should be a priority for all. Work along this line has been done in the United States and Canada. In light of the impact on public health, it is important to rapidly develop guidelines and regulations for piercing in France. Both professional piercers and health care workers should participate in developing these safety measures in order to assure their implementation.

RESUMEN

OBJECTIVES: (1) To determine the incidence and outcome of Pseudomonas aeruginosa infection in HIV-infected patients. (2) To study the antimicrobial susceptibility of P. aeruginosa isolates in this particular population. (3) To identify risk factors for these infections. PATIENTS AND METHODS: A retrospective case-control study performed in a 28-bed infectious-diseases unit in a 940-bed university hospital. All cases were defined as HIV-infected patients with severe infections due to P. aeruginosa, including bacteremia, lower or upper respiratory tract infections, infections related to a central venous catheter, and cutaneous/muscular infection. Each case was matched with an HIV-seropositive control not infected by P. aeruginosa and hospitalized on the same dates as the cases. RESULTS: One thousand and thirty-five HIV-infected patients were hospitalized during the study period. A first severe P. aeruginosa infection was documented in 41 patients, giving an overall annual incidence note of 2.51 episodes per 100 admissions. Forty of the 41 case notes were available for analysis. They consisted of 17 cases of bacteraemia, four upper respiratory tract infections, 10 lower respiratory tract infections, three catheter-related infections, and six cutaneous/muscular infections. Of these 40 cases, 60% were nosocomial and the remainder were community-acquired. The overall mortality rate was 22% (47% in bacteraemic forms). Twenty five percent of patients relapsed after an average of 37 days. The case-control comparison showed that AIDS was more frequent among the cases (92% vs. 74%, P = 0.04), who also had a lower PN count (P = 0.005), and a lower CD4 cell count (15.7 +/- 18.8/mm3 vs. 118 +/- 211/mm3; P = 0.0007). The number of days spent in hospital in the previous 3 months (29.3 +/- 20.7 vs. 19.7 +/- 14, P = 0.04) was significantly higher among the cases. In a multivariate analysis, examining treatments received in the previous month, only co-trimoxazole [OR = 5.5 (1.1-26.9)], penicillins [OR = 5.2 (1.1-25.3)], steroids [OR = 5.5, (1.2-25.5)] and a CD4 cell count below 50/mm3 [OR = 13.2 (1.4-129.4)] were identified as risk factors. CONCLUSION: P. aeruginosa infection is a not frequent bacterial disease in highly immunodeficient HIV-infected patients. It is frequently fatal and must be borne in mind in the advanced stages of HIV disease, especially when patients have received co-trimoxazole (trianthoprim-sulphamethoxazole), penicillins or steroids.

RESUMEN

BACKGROUND: Paragonimiasis, caused by a lung fluke, is an parasitic disease rarely encountered in France. CASE REPORT: A 52-year-old man developed dyspnea, cough, mild fever and chest pain. Pleural effusion suggested possible pulmonary embolism or tuberculosis. Cell counts in blood and pleural effusion fluid revealed major eosinophila in this patient who had recently returned from a trip to Japan. Paragonimiasis was confirmed by ELISA. Treatment with praziquantel led to complete clinical and radiographic recovery. DISCUSSION: The clinical and radiographic features of paragonimiasis are often similar to tuberculosis with pleuropneumopathy, mild fever and dyspnea. ELISA has now replaced parasitologic diagnosis. Cure is achieved with praziquantel.

RESUMEN

A prospective cohort study on the mother-to-child transmission of human immunodeficiency virus type 1 (HIV1), type 2 (HIV2) and dual positivity (HIV1 + HIV2) was carried out in Banfora, West Burkina Faso. The study samples consist of 117 newborns of HIV-seropositive women matched to 234 newborns of HIV-seronegative women. Among cases, 91 were born of HIV1-seropositive mothers, 15 were born of HIV2-seropositive mothers and 11 were born of HIV1 and HIV2 dual-seropositive mothers and were included in an 18-month follow-up. Calculation of the mother-to-child transmission rate was according to the recommendations of the European Economic Community working group. The HIV1 mother-to-child transmission rate was estimated to be 27.8% (95% confidence interval (CI) 24.5 to 32.4) with one method and 25.5% (95% CI 13.5 to 37.5) with a second method. For HIV2, this rate was estimated to be 29.5% (95% CI 26.0 to 39.8) and was not statistically different from the HIV1 mother-to-child transmission rate. No case of transmission was observed in children born of dual seropositive mothers. Survival rate at month 18 was significantly lower for children born of HIV1 mothers: 83.7% (95% CI 78.2 to 92.2). Survival rates were similar between children born of HIV2-seropositive (86.7), dual HIV1 + 2-positive (100) and seronegative mothers (92.0%). Findings suggest a higher mother-to-child transmission rate of HIV2 in children born in Burkina Faso than in Europe and a low clinical expression of HIV2 in children.

RESUMEN

The obstetrical referral patients admitted to the Sanon Souro hospital in Bobo-Dioulasso (Burkina Faso) during 1991 were retrospectively reviewed. During the study period 741 women were admitted. The median distance between the referring centre and Bobo-Dioulasso was 33 km. Median age was 22 years and median parity was 3. Indications for referral were dominated by obstructed labour, haemorrhages and infections. The proportion of maternal mortality in the study was 5.4% and was not related to maternal age or parity. However, there was a linear trend of increasing mortality according to the distance between the referring centre and Bobo-Dioulasso (X2 for trend: 7.56; p = 0.006). The perinatal mortality rate of 420 p. thousand was not related to maternal age, but a parity exceeding 4 was a risk factor for the occurrence of perinatal death (relative risk: 1.4; 95% C.I.: 1.2-1.7). As for maternal mortality, there was a linear increase of perinatal mortality with the distance from the referring centre (X2: 20.8; p = 0.00001). There was no marked seasonal variation in the number of referrals nor in the mortality rates per month.
