Insulin therapy in childhood type 1 diabetes: Knowledge and practice in Senegal.

INTRODUCTION: Childhood type 1 diabetes (T1D) is a chronic condition with serious repercussions on both the quality of life of the child and the family. Insulin therapy is the cornerstone of optimal blood sugar control. The main objective of our study was to assess the level of knowledge of physicians about insulin therapy in diabetes. METHODS: This was a multicenter survey over a period of 5 months (from March 5 to August 2, 2018). It took place in five reference university hospital centers in the Dakar region. RESULT: The number of doctors interviewed in our study was 82, 47.6% of whom were confirmed pediatricians or pediatricians in the process of specialization. The number of years of experience in the field of diabetes was on average 3 years. Fast-acting regular insulins were recommended by 75.6% of doctors and mixtures of insulin (intermediate and rapid-acting) by 50% of doctors. Overall, 91% of doctors recommend a variation in insulin injection sites. The "basal bolus" treatment regimen with insulin analogs was recommended by 50% of doctors, while 31.7% recommended it with human insulin. Regarding adapting insulin doses for leisure and sports activities, more than half (54.9%) of the doctors had to reduce the doses. CONCLUSION: This study enabled us to assess the level of knowledge of insulin therapy among doctors caring for children with diabetes in Senegal, which proved to be limited. We recommend the reinforcement and follow-up of training on the management of T1D for providers at the different facilities.

[Interest of ambulatory simplified acute physiology score (ASAPS) applied to patients admitted in an intensive care unit of an infectious diseases unit in Dakar]. / Intérêt de l'indice de gravité simplifié ambulatoire (IGSA) appliqué à des patients admis dans l'unité de soins intensifs (USI) d'un service de pathologie infectieuse à Dakar.

The evaluation of patients by a scale of gravity allows a better categorization of patients admitted in intensive care unit (ICU). Our study had for objective to estimate interest of Ambulatory Simplified Acute Physiologic Score (ASAPS) applied to patients admitted in ICU of infectious diseases department of FANN hospital. It was about a descriptive and analytical retrospective study, made from the data found in patients' files admitted into the USI infectious diseases department of FANN hospital in Dakar, from January 1(st), 2009 till December 31st, 2009.The data of 354 patients' files were analyzed. The sex-ratio was 1.77 with an average age of 37.6 years ± 19.4 years old [5-94 years]. The majority of the patients were unemployed paid (39.6%). The most frequent failures were the following ones: neurological (80.5%), cardio-respiratory (16.7%). The average duration of stay was 6.2 days ± 8.2 days going of less than 24 hours to more than 10 weeks. The deaths arose much more at night (53.1%) than in the daytime (46.9%) and the strongest rate of death was recorded in January (61.5%), most low in October (26.7%). The global mortality was 48.3%. The rate of lethality according to the highest main diagnosis was allocated to the AIDS (80.5%). The average ambulatory simplified acute physiology score was 5.3 ± 3.6 with extremes of 0 and 18. The deaths in our series increased with this index (p = 0.000005). The female patients had a rate of lethality higher than that of the men people, 55.5% against 44.2% (p = 0.03). In spite of a predictive score of a high survival (ASAPS < 8), certain number of patients died (n = 105) that is 61.4% of the deaths. The metabolic disturbances, hyperleukocytosis or leukopenia when realised, the presence of a chronic disease, seemed also to influence this lethality. ASAPS only, although interesting, would not good estimate the gravity of patients, where from the necessity thus of a minimum biological balance sheet. It seems better adapted for patients with a high value (ASAPS≥8). This score when it is low, is not correlated, in our study, at a high survival rate as waited in this population.

Influence of HIV-1 and/or HIV-2 infection and CD4 count on cervical HPV DNA detection in women from Senegal, West Africa.

BACKGROUND: HIV infection is associated with greater risk of precancerous lesions and cervical cancer in women. However, several factors remain unclarified regarding the association between HIV infection and HPV detection, especially among those with HIV type 2 versus type 1 infection and severely immunocompromised persons. OBJECTIVES: To evaluate HPV overall and type-specific detection among HIV-infected and uninfected women in Senegal. STUDY DESIGN: Detection of HPV DNA for 38 genotypes in cervical swabs using PCR-based methods was evaluated in HIV-positive (n=467) and HIV-negative (n=2139) women participating in studies in Senegal. Among HIV-1 and/or HIV-2 positive women, CD4 counts were assessed. Adjusted multivariable prevalence ratios (PR) were calculated. RESULTS: The prevalence of any HPV DNA and multiple HPV types was greater among HIV-infected individuals (78.2% and 62.3%, respectively) compared with HIV-negative women (27.1% and 11.6%). This trend was also seen for HPV types 16 and 18 (13.1% and 10.9%) compared to HIV-negative women (2.2% and 1.7%). HIV-infected women with CD4 cell counts less than 200 cells/µl had a higher likelihood of any HPV detection (PRa 1.30; 95% CI 1.07-1.59), multiple HPV types (PRa 1.52; 95% CI 1.14-2.01), and HPV-16 (PRa 9.00; 95% CI 1.66-48.67), but not HPV-18 (PRa 1.20, 95% CI 0.45-3.24) compared to those with CD4 counts 500 cells/µl or above. CONCLUSION: HIV-infected women, especially those most severely immunocompromised, are more likely to harbor HPV. Measures to prevent initial HPV infection and subsequent development of cervical cancer through focused screening efforts should be implemented in these high risk populations.

[Evaluation of tolerance of zidovudine-lamivudine-nevirapine combination in HIV 1 patients in Fann Teaching Hospital in Dakar]. / Évaluation de la tolérance de l'association zidovudine-lamivudine-névirapine chez les patients VIH-1 au Centre hospitalier de Fann à Dakar.

We conducted a study to evaluate the tolerance of the zidovudine (AZT), lamivudine (3TC) and nevirapine (NVP) combination regimen in HIV-1 patients by a descriptive analytical retrospective study of all HIV-1 patients receiving AZT-3TC-NVP combination between 2008 and 2011. Seventy patients were included. Two thirds of the patients presented at least one side effect (44 cases). The digestive disorders (15 cases) and neuropsychiatric (14 cases) were the most frequent. Epigastralgia (20%), headaches (20%) and arthralgias (13%) were main side effects. A maculo-papular exanthema was noted in three cases. During the follow-up, five patients presented with anemia. No patient presented hepatic cytolysis due to NVP. All the patients followed for more than six months presented a side effect against 29.7% when the duration of treatment was equal to or less than 6 months (p=10(-5)). Most of the side effects due to the association AZT/3TC/NVP are minor. The evaluation of the clinical and biological tolerance must be maintained during all the follow-up.

[Current profile of cerebral toxoplasmosis in a hospital setting in Dakar]. / Profil actuel de la toxoplasmose cérébrale en milieu hospitalier à Dakar.

OBJECTIVE: To describe the current epidemiologic, clinical, diagnostic, and prognostic characteristics of cerebral toxoplasmosis in a hospital setting in Dakar. METHODS: This descriptive and analytic study examined the records of all HIV-positive patients with cerebral toxoplasmosis hospitalized at the infectious disease department at Fann (teaching) Hospital from January 2007 through December 2010. The diagnosis was based on clinical and computed tomography criteria completed by a therapeutic test with Cotrimoxazole. RESULTS: There were 26 cases of cerebral toxoplasmosis during the study period. The sex ratio (F/M) was 1.4. The mean age was 41.5 ± 11.2 years. The clinical signs were predominantly fever (88.5%), headache (77.5%), focal signs (64.5%), and disorders of consciousness (61.5%). Brain lesions were most often multiple (64.3%), with mass effects (54.1%) and peripheral edema (77.8%). Seven of the 26 patients died (lethality rate: 29.1%). Impaired consciousness (p = 0.023), high CD8 T-cell counts (p = 0.009), and anemia (p = 0.003) were significantly associated with a higher mortality rate. CONCLUSION: Cerebral toxoplasmosis remains a complication of AIDS in Dakar. Anemia, impaired consciousness, and high CD8(+) T cell counts were factors indicative of poor prognosis.

[Elimination of maternal and neonatal tetanus in Senegal: evolution of survey indicators of 2003-2009]. / Élimination du tétanos maternel et néonatal au Sénégal : évolution des indicateurs de surveillance de 2003 à 2009.

OBJECTIVES: This study aimed to estimate the evolution of the maternal and neonatal tetanus in Senegal from the tetanus vaccination coverage among pregnant women, the proportion of deliveries attended by trained medical personnel and the number of cases of tetanus declared by respective districts, helping to identify districts at high risk of neonatal tetanus (NNT). METHOD: Data analysis of the epidemiological surveillance realized from 2003 to 2009 in 65 districts of Senegal. Data were collected from the reports of vaccination usage and from the Statistical Directories of the National Health Information Services of the Ministry of Health & Prevention. A district is at high risk when the incidence of NNT is ≥1 case per 1 000 Live births (LB). RESULTS: There were 153 reported cases of NNT in Senegal between 2003 and 2009. National incidence decreased from 0.08 to 0.03 case per 1 000 LB (p = 0,0008). The vaccination coverage of the pregnant women by at least two doses of tetanus vaccine (VAT2+) increased from 66% in 2003 to 78% in 2009. The percentage of districts that had reached a vaccination coverage ≥80% was 20% in 2003 compared to 60% in 2009 (p = 0.009). The proportion of deliveries attended by qualified medical staff evolved from 53% in 2003 to 67% in 2009 (p = 0,02). By 2009, the incidence of NNT was less than 1 case per 1,000 LBs in all districts. CONCLUSION: Assessing the elimination of maternal and neonatal tetanus in Senegal shows that progress has been made from 2003 to 2009. This was made possible through the organization of vaccination campaigns for women of childbearing age and the improvements in the conditions of deliveries.

[Efficacy and tolerance of tenofovir-lamivudine-efavirenz combination in HIV-1 patients in Fann Teaching Hospital in Dakar]. / Efficacité et tolérance de l'association ténofovir-lamivudine-éfavirenz chez les patients VIH-1 à la clinique des maladies infectieuses du CHNU de Fann à Dakar.

We conducted a study to evaluate the efficacy and tolerance of the tenofovir (TDF), lamivudine (3TC) and efavirenz (EFV) combination regimen in HIV-1 patients by a descriptive analytical retrospective study of all HIV-1 patients receiving TDF-3TC-EFV combination between 2007 and 2011. Collected data was analysed using EpiInfo™ version 6.04. One hundred patients were included, with an average follow-up duration of 27 months and 19 days (± 21 months and 14 days).We observed an average increase in body weight of about 8 kg per annum, with an average rise in CD4 count of 100/mm(3) by the end of the second year. A reduction in viral load with 71% of patients in therapeutic success at 24 month of treatment was noted. Ninety-two patients presented with at least one side effect, mostly being Grade 1 or 2 (96.36%). Neurological (24 patients) and digestive (20 patients) complaints comprised the commonest reported side effects. Four patients had adverse effects severe enough to warrant a change in treatment regimen, principally due to renal insufficiency. Thirteen subjects died. Patients receiving TDF-3TC-EVF combination therapy need rigorous surveillance because this combination, although efficient, is not without significant adverse effects.

Association between herpes simplex virus type 2 and HIV-1 in a population of married couples from Dakar, Senegal.

Numerous studies suggest that herpes simplex virus type 2 (HSV-2) increases the risk of HIV-1 infection but recent clinical trials of HSV-2 suppressive therapy failed to show an effect. We assessed the putative association between HSV-2 and HIV-1 in a population of HIV-concordant-negative, HIV-1-discordant and HIV-1-concordant-positive married couples from Dakar, Senegal. In agreement with previous studies, we observed a strong overall association between HSV-2 and HIV-1 (odds ratio 4.61; P < 0.001). However, this association was mainly determined by a low HSV-2 prevalence in HIV-concordant-negative couples compared with HIV-1-discordant and HIV-1-concordant-positive couples (23% versus 59% and 66%, respectively; P < 0.001). We observed no further differences in HSV-2 prevalence between HIV-1-discordant and HIV-1-concordant-positive couples (59% and 66%, respectively; P = 0.483). Neither the index (59% versus 62%, P = 1.000) nor recipient partners (41% versus 63%, P = 0.131) in HIV-1-discordant and HIV-1-concordant-positive couples showed significant differences in HSV-2 prevalence. HSV-2 does not constitute a clear risk factor for HIV-1 infection in this population.

Trends of HIV-1, HIV-2 and dual infection in women attending outpatient clinics in Senegal, 1990-2009.

We assessed trends in the relative prevalences of HIV-1, HIV-2 and dual HIV-1/HIV-2 infection in 10,321 women attending outpatient clinics in Senegal between 1990 and 2009. The relative prevalence of HIV-1 (defined as the proportion of seropositive subjects having HIV-1) rose sharply from 38% in 1990 until 1993 (P < 0.001), whereupon it continued to rise, but at a slower rate, reaching 72% of HIV infections in 2009. As compared with HIV-1, the relative prevalence of HIV-2 decreased sharply from 54% in 1990 until 1993 (P < 0.001) and continued to decrease at a slower rate through 2009. The relative prevalence of dual infection, as compared with HIV-1, was stable from 1990 to 1993, but decreased slightly thereafter (P < 0.001). These study findings indicate that during the early 1990s, the relative prevalence of HIV-1 increased markedly, while the relative prevalence of HIV-2 decreased and the relative prevalence of dual infection remained stable in Senegal. From 1993 to 2009, the relative prevalence of HIV-1 increased at a slower rate, while the relative prevalences of HIV-2 and dual infection decreased. These results confirm trends in HIV prevalence observed in other West African populations and provide a critical update on HIV transmission risk among women in Senegal.

[Current profile of HIV-infected patients hospitalized in Dakar (Senegal)]. / Profil actuel des patients infectés par le VIH hospitalisés à Dakar (Sénégal).

Ten years after the introduction of the Senegalese Antiretroviral Drug Access Initiative in 1998, we conducted a retrospective study of the epidemiological and clinical profiles and outcome of HIV-infected patients hospitalized in the Infectious Diseases Clinic of Fann Teaching Hospital in Dakar between 2007 and 2008. During these 2 years, 527 HIV-positive patients were included. The average age of the patients was 41 ± 10 years, and the sex-ratio (F/M) was 1.1; 56% of patients were married. The average interval before admission was 40 ± 57 days. Fever (83%), loss of weight (83%) and cough (54%) were the principal symptoms. Tuberculosis (40.9%) and gastrointestinal candidiasis (38.9%) were the commonest opportunistic infections. Most patients were diagnosed at the AIDS stage (88%) and the CD4+ T lymphocyte count was ≤ 200/mm3 in 86% of cases. Hospital fatality was 44% (231/527). Tuberculosis (36%), bacterial pneumonia (18%) and encephalitis (12%) were the most frequent causes of death. Despite the availability of and free access to antiretroviral drugs in Senegal, the mortality associated with HIV infection remains very high due to late diagnosis. The population must be educated to boost early screening and care.

Tuberculosis in HIV programmes in lower-income countries: practices and risk factors.

BACKGROUND: Tuberculosis (TB) is a common diagnosis in human immunodeficiency virus (HIV) infected patients on antiretroviral treatment (ART). OBJECTIVE: To describe TB-related practices in ART programmes in lower-income countries and identify risk factors for TB in the first year of ART. METHODS: Programme characteristics were assessed using standardised electronic questionnaire. Patient data from 2003 to 2008 were analysed and incidence rate ratios (IRRs) calculated using Poisson regression models. RESULTS: Fifteen ART programmes in 12 countries in Africa, South America and Asia were included. Chest X-ray, sputum microscopy and culture were available free of charge in respectively 13 (86.7%), 14 (93.3%) and eight (53.3%) programmes. Eight sites (53.3%) used directly observed treatment and five (33.3%) routinely administered isoniazid preventive treatment (IPT). A total of 19 413 patients aged ≥ 16 years contributed 13,227 person-years of follow-up; 1081 new TB events were diagnosed. Risk factors included CD4 cell count (>350 cells/µl vs. <25 cells/µl, adjusted IRR 0.46, 95%CI 0.33-0.64, P < 0.0001), sex (women vs. men, adjusted IRR 0.77, 95%CI 0.68-0.88, P = 0.0001) and use of IPT (IRR 0.24, 95%CI 0.19-0.31, P < 0.0001). CONCLUSIONS: Diagnostic capacity and practices vary widely across ART programmes. IPT prevented TB, but was used in few programmes. More efforts are needed to reduce the burden of TB in HIV co-infected patients in lower income countries.

[Human rabies: diagnostic pitfalls]. / La rage humaine, un diagnostic parfois difficile.

The purpose of this report is to describe two cases of human rabies in Senegal that illustrate possible diagnostic and therapeutic pitfalls even in an endemic area. Although outcome is almost always fatal and interhuman transmission is uncommon, prompt diagnosis of rabies is important since delay increases the risk of exposure to the virus for the entourage.

[Aetiology of AFB negative pneumonias in hospitalized HIV patients in Dakar]. / Étiologie des pneumonies BAAR négatives chez les patients infectés par le VIH hospitalisés à Dakar (étude ANRS 1260).

A prospective study was carried out in two tertiary hospitals in Dakar to determine the main causes of sputum acid-fast bacillus (AFB) smear-negative pneumonia in HIV-infected patients. All clinical and microbiological records were reviewed by experts. Seventy patients were finally enrolled. Most of them were hospitalized at an advanced stage of AIDS. The median CD4 cell count was 62/mm(3) and the median body mass index (BMC) was 18 kg/m(2). Thirty-one patients (44 %) were known as seropositive for HIV infection prior to admission. Radiological opacities were localized in 70 % of patients and diffuse in 21 %. Fiberoptic bronchoscopy was performed in 50 patients (71 %). A definite or probable diagnosis was obtained in 55 patients (79 %). Bacterial pneumonia (usually due to Enterobacteriaceae and Pseudomonas aeruginosa), tuberculosis, Pneumocystis pneumoniae and other causes (Kaposi's sarcoma, atypical mycobacteria) were diagnosed in 67 %, 24 %, 5 %, and 13 % of these patients respectively. In conclusion, pneumonia of bacterial origin and tuberculosis can be incriminated in the majority of cases of AFB negative pneumonia observed in HIV patients in Dakar.

Efficacy and safety of unboosted atazanavir in combination with lamivudine and didanosine in naive HIV type 1 patients in Senegal.

The use of ritonavir as a protease inhibitor boost is rare in sub-Saharan Africa because a heat-stable formula is not available. We report the results of an open-label pilot trial with unboosted atazanavir in combination with lamivudine and didanosine as first-line therapy conducted in Senegal. Treatment-naive HIV-1 infected adult patients without active opportunistic disease were included. The primary endpoint was the proportion of patients with plasma HIV-1 RNA <400 copies/ml at week 48. Forty patients (12 men and 28 women; mean age +/- SD: 40 +/- 9 years) were included. Treatment was changed during the study for two patients (pregnancy, tuberculosis); one patient was lost to follow-up and one patient died (gastroenteritis with cachexia). At week 48, 78% [95% confidence interval (CI): 65-90%] and 68% (95% CI: 53-82%) of the patients had HIV-1 RNA <400 and <50 copies/ml, respectively (intent-to-treat analysis; not completer = failure). Among the seven patients with HIV-1 RNA >or=400 copies/ml at week 48, five were not compliant; genotyping analysis (n = 4) did not reveal a major mutation for protease inhibitors. The mean CD4 cell count change from baseline to week 48 was +238 +/- 79 cells/mm(3). The combination of unboosted atazanavir with lamivudine and didanosine was efficient and well tolerated in HIV-1-infected patients with results similar to those observed in Northern countries. These results suggest that unboosted atazanavir with its high genetic barrier could be a valuable alternative to NNRTIs in resource-limited countries in some HIV-1-infected patients in case of compliance issues with NNRTIs, intolerance to NNRTIs, resistance mutations to NNRTIs, in women with childbearing potential, or as a maintenance therapy in patients with virological suppression.

[Maternal tetanus in Dakar from 2000 to 2007]. / Tétanos maternel à Dakar de 2000 à 2007.

The objective of this study conducted between January 2000 and December 2007 was to assess the current epidemiological, clinical and outcome features of maternal tetanus (MT) observed in the Infectious Diseases Clinic of Fann University Hospital in Dakar, Senegal. A total of 1156 patients were admitted for tetanus during this period including 9 (0.8%) presenting MT. A progressive decrease in the annual number of MT cases was observed. The mean age of MT patients was 28.3 years [range, 18 to 40 years]. Most cases (n=6) involved persons living in suburban areas, as did tetanus in women of childbearing age (WCBA) (51.9% of 129 cases) and in neonates (63.1% of 103 cases) admitted during the same period. All patients had fallen behind the vaccination schedule. Septic abortion (n=7) was the main etiological factor. Although tetanus was graded as moderate in 8 patients (Mollaret stage 2), the death rate was high (44.4%) due to infectious and obstetric complications. This rate was similar to that associated with tetanus in newborns (48.5%), but higher than that associated with tetanus in WCBA (25.6%). The incidence of life-threatening MT is declining in the Infectious Diseases Clinic of Fann University Hospital in Dakar. A systematic immunization program along with campaigns to prevent unwanted pregnancy in women of childbearing age will be needed to eliminate maternal and newborn tetanus in Dakar.

[Time trends in demographic and clinical characteristics of adult patients on HAART initiation in West Africa]. / Evolution des conditions d'initiation du traitement antirétroviral des patients infectés par le VIH en Afrique de l'Ouest.

OBJECTIVE: We studied the evolution of drug combinations used, as well as the clinical and immunological profile of patients at initiation of highly active antiretroviral therapy (HAART) between 1996 and 2006 in West Africa. SETTINGS AND METHOD: IeDEA West Africa is a network of HIV care programs established in 2006. We analyzed data from 12 clinical centers treating adults in five countries: Benin, Cote d'Ivoire, Senegal, Gambia, and Mali. Patients 16 years of age or over were included in the study and the following was documented: sex, date of birth and date of initiation of HAART. RESULTS: We included 14,496 adult patients having started HAART, among these 55 % had started HAART between 2005-2006. The proportion of HIV-infected women increased from 46 % in 1996-2000 to 63 % in 2005-2006. The median age at HAART initiation remained constant: 35 years for women and 40 years for men. The proportion of patients having started HAART with a CD4 count<200 cells/microl was 54 % in 1996-2000, and 64 % in 2005-2006. The most frequently prescribed HAART was: AZT/3TC (or d4T/DDI)/IDV (27 %) in 1996-2000; d4T (or AZT)/3TC/EFV (49 %) in 2003-2004, and d4T/3TC/NVP (49 %) in 2005-2006. CONCLUSION: The first line HAART regimen recommended by WHO was initiated in 83 % of cases in 2005-2006. New approaches to an earlier initiation of ART should be explored to reduce mortality in HIV-infected patients on HAART.

[Tetanus in women of childbearing age at the infectious diseases clinic in Dakar]. / Le tétanos de la femme en age de procréer a la clinique des maladies infectieuses de Dakar.

The objective of this article was to describe the epidemiological and outcome features of tetanus in the woman of childbearing age (WCBAT) and compare them with neonatal tetanus (NT) and other tetanus cases in a hospital department in Dakar from 1998 to 2007. A retrospective study was conducted using the files of WCBAT (15 to 49 years old), NT (3 to 28 days old) and other tetanus cases admitted at the Infectious Diseases Clinic, in Fann University Hospital, from 1998 to 2007. 1484 cases of tetanus were admitted in 10 years, with 176 cases of tetanus of WCBAT (11.8%) and 178 cases of NT (11.9%). In comparison with WCBAT the NT annual hospital rate significantly decreased during the study period whereas other tetanus cases rate remained stable. The average age of WCBAT was 26.1 year old and 57.9% were between 15 and 25 years old. The geographical origin was identical for all patients, with more than 71% coming from suburban areas. Most of the WCBAT cases were housewives (50.9%), single women (75%) without updated tetanus immunization (92%). The main portals of entry of WCBAT were injuries and wounds (67.4%) and maternal tetanus cases were rare (8%), mainly post-abortum. At admission, WCBAT cases were less severe than NT cases but more severe than other tetanus cases. The lethality rate of WCBAT cases (28.4%) was significantly lower than NT cases (50%, p = 0.00003), but higher than the other tetanus cases (22.2%; NS). Prognostic factors were: non-identified or intramuscular injection portal of entry and a Mollaret state III at admission. An intensification of the extended immunization program associated with supplementary immunization campaigns targeting women of child bearing age in high risk districts, are necessary to eradicate neonatal and maternal tetanus in Dakar.

[Knowledge, behaviors and practices among ironworkers about tetanus in Senegal]. / Connaissances, attitudes et pratiques a propos du tétanos chez les ferronniers a Dakar, Sénégal.

Tetanus is still a major health problem in Sénégal. In order to understand some of these reasons, we conducted a study. The aim of this study is to assess ironworkers' knowledge, behaviors and practices about tetanus. This knowledge, behaviors and practices survey was carried out in ironworks of two neighborhoods of Dakar from April 5 to May 10, 2008. 41 ironworks were identified and 32 agreed to participate in the study. In this ironworks, 120 ironworkers were interviewed. Their average age was 29 years +/- 15, education in French schools was low and 78.3% of them had a source of information. Despite some inaccuracies, most ironworkers were aware of tetanus (97.5%), severity (93.3%), causes (89.2%). However 35% did not evaluate the risk of tetanus and almost all the ironworkers or 96.7% had no preventive measures after injury. Moreover, no ironworker was fully immunized against tetanus. In some occupations at risk, awareness of tetanus should be increased by all available channels and methods emphasizing the importance of prevention.

Tenofovir-emtricitabine-efavirenz in HIV-I-infected adults in Senegal: a 96-week pilot trial in treatment-naive patients.

We report the results of a pilot open-label trial of a tenofovir (TDF)/emtricitabine (FTC)/efavirenz (EFV) combination conducted in Dakar, Senegal. Forty HIV-1-infected patients, naive of antiretroviral treatment and without active opportunistic disease, were included and followed through 96 weeks. At weeks 48 and 96, respectively, 82.5% and 85% of patients had HIV-1 RNA <400 copies/mL (72.5% and 77.5% with HIV-1 RNA <50 copies/mL). Between baseline and week 96, the mean (SD) CD4 count increased from 126 (102) to 338 (155) cells/mm(3). The mean (SD) creatinine clearance decreased from 92 (36) to 73 (19) mL/min (P = .001). Treatment adherence was at least 94% at all scheduled visits. The efficacy and tolerability of a TDF/FTC/EFV combination were high and similar to those observed in Northern countries. This drug combination can be recommended in limited-resource countries, as did the World Health Organization (WHO) and should be made readily available as a fixed-dose combination.
