RESUMEN

AIMS: To evaluate the maintenance of efficacy and safety of insulin glargine 300 U/ml (Gla-300) versus glargine 100 U/ml (Gla-100) in people with type 2 diabetes mellitus (T2DM) using basal plus meal-time insulin for 12 months in the EDITION 1 trial. METHODS: EDITION 1 was a multicentre, randomized, open-label, two-arm, phase IIIa study. Participants completing the initial 6-month treatment period continued to receive Gla-300 or Gla-100, as previously randomized, once daily for a further 6-month open-label extension phase. Changes in glycated haemoglobin (HbA1c) and fasting plasma glucose concentrations, insulin dose, hypoglycaemic events and body weight were assessed. RESULTS: Of 807 participants enrolled in the initial phase, 89% (359/404) assigned to Gla-300 and 88% (355/403) assigned to Gla-100 completed 12 months. Glycaemic control was sustained in both groups (mean HbA1c: Gla-300, 7.24%; Gla-100, 7.42%), with more sustained HbA1c reduction for Gla-300 at 12 months: least squares mean difference Gla-300 vs Gla-100: HbA1c -0.17 [95% confidence interval (CI) -0.30 to -0.05]%. The mean daily basal insulin dose at 12 months was 1.03 U/kg for Gla-300 and 0.90 U/kg for Gla-100. Lower percentages of participants had ≥1 confirmed [≤3.9 mmol/l (≤70 mg/dl)] or severe hypoglycaemic event with Gla-300 than Gla-100 at any time of day [24 h; 86 vs 92%; relative risk 0.94 (95% CI 0.89-0.99)] and during the night [54 vs 65%; relative risk 0.84 (95% CI 0.75-0.94)], while the annualized rates of such hypoglycaemic events were similar. No between-treatment differences in adverse events were apparent. CONCLUSION: During 12 months of treatment of T2DM requiring basal and meal-time insulin, glycaemic control was better sustained and fewer individuals reported hypoglycaemia with Gla-300 than with Gla-100. The mean basal insulin dose was higher with Gla-300 compared with Gla-100, but total numbers of hypoglycaemic events and overall tolerability did not differ between treatments.

RESUMEN

This prospective study included all the patients who, during the month of September 1995, were admitted for pulmonary baclliferous tuberculosis to the Pneumology Clinic of the Fann University Hospital, Dakar. The patient's escorts and the health personnel were also included in this study. The aim of the study was to find the different socio-economic and health factors impeding the hospitalization of tuberculosis patients in the Pneumology Clinic of Fann University Hospital. 22 members of the health team, 209 patients aged between 15 and 65 years and 209 escorts were interviewed. Out of the 10% of tuberculosis patients with HIV seropositivity, 80% admitted not to have informed their spouses of their infection. The decision to be admitted was made by the patient himself in 54.4% of cases and by his family in 45.5% of cases. Late admittance with regards to the beginning of symptoms was due to the recourse to traditional medicine in 43.7% of cases, wrong diagnosis in 24%, ignorance in 19.3% and, in 13% of cases, due to inappropiate anti tuberculosis treatment. Despite the fact that anti tuberculosis medicine was free of charge, each patient or his family spent an average sum of 87,500 CFA F (US dollar 175) for a month's admission (the minimal salary (SMIG) in Senegal is 32,000 CFA F (US dollar 64), and 40% of the patients and escorts had difficulties making this payment. 9 patients were judged to be poor by 25.7% of the patients and 8.7% found relations with the health personnel difficult. The escorts deplored the lack of toilets (only 1 out of 4 was functional), the time worn facilities, the overcrowding as well as the irregularity and poor quality of the hospital meals. The entire health team deplored the lack of adequate personnel and 30% of them deplored the lack of hygiene of some patients and escorts. Taking financial charge of tuberculosis patients at the Pneumology Clinic of the Fann University Hospital requires an increased financial effort from the State (rehabilitation of the facilities, recruitment of medical and paramedical personnel, improved meals) harmonisation on a national scale of anti tuberculosis therapeutic protocoles and an Information-Education-Communication (IEC) programme on tuberculosis and hygiene.

RESUMEN

The Acute Chest Syndrome (ACS) is defined by the association of chest pain with dyspnea, fever, a recent radiological abnormality and hyperleucocytosis. Acute pulmonary complications are the primary cause of mortality in sickle cell patients. We report a 19-year old male patient with homozygous sickle cell anemia who consults for respiratory symptomatology and bone algia. The diagnosis of ACS by left pneumopathy due to pneumococcal infection was based on the clinical tests, chest x-ray and blood culture. The appearance of pneumopathy in patients suffering from sickle cell anemia is explained by the functional asplenia and the inability of phagocyte cells to destruct bacteria. These incidents are triggered by alveolar hypoventilation, fat embolism from bone infarction, infections, pulmonary oedema and thrombosis. The evolution of these ACS by pneumopathy depends on their early diagnosis and treatment but also on the sensitivity of the germs to antibiotics.

RESUMEN

National immunization and control programs have not brought about a significant decline in tuberculosis, which remains a real public health concern in our regions. Prevention in the working environment should be part of an overall prevention program for the general population. Nevertheless, companies should play a leading role because they have the necessary structure and assets. We analyzed the epidemiology of tuberculosis in the working environment using demographic data on employees in Senegal, current medicolegal data on tuberculosis in Senegal and data on prevention of tuberculosis. Our analysis led to a proposed strategy for controlling tuberculosis spread and its prevention in the working environment in Senegal.

RESUMEN

Our objectives were to describe hemato-immunological abnormalities encountered in tuberculosis patients HIV seropositive (TBVIH+, n = 67) or not (TBVIH-, n = 39) and in HIV asymptomatic patients (aSVIH+, n = 40). We found: a great reduction of mean value of RBC and Hb in TBVIH+ and TBVIH-; a reduction of mean value of leucocytes, total lymphocytes and CD4+ lymphocytes in TBVIH+ and aSVIH+; an inversion of [formula: see text] ratio, more important in TBVIH+ than in aSVIH+. HIV and tuberculosis association, HIV1 serotype and CD4 < 200/mm3 were found to promote significantly hemato-immunological abnormalities.

RESUMEN

The industrial development policy adopted by African countries since their independence has contrasted with the relative rarity of occupational asthma in workers exposed to different situations and substances known to generate occupational asthma. Asthma occurring in a Senegalese car sprayer had persisted for twenty years before the its work-related nature was recognized. This observation demonstrates the need for: 1. Education to make health care personnel, as well as workers and employers, more aware of the clinical aspects of asthma. Educational programs should include diagnostic and preventive measures for respiratory occupational diseases including occupational asthma. 2. A registration system for occupational diseases so the occupational nature of diseases can acquire legal recognition. 3. Cooperative efforts between general practitioners, occupational physicians, physiologists and lung specialists in order to create reference laboratories where tests can be performed to confirm the diagnosis of occupational asthma, a disease which has not yet been included on the list of occupational diseases.

RESUMEN

SETTING: Two teaching hospitals in Dakar, Senegal, a West African country with a low prevalence of human immunodeficiency virus (HIV) infection. OBJECTIVE: To determine whether patients with HIV-associated pulmonary tuberculosis have fewer acid-fast bacilli (AFB) in their sputum as assessed by routine microscopy, and to correlate the findings with systematically obtained clinical, radiographic and laboratory variables. DESIGN: Prospective study from November 1995 to October 1996 of 450 consecutive patients diagnosed with pulmonary tuberculosis. RESULTS: Tuberculosis was diagnosed in 380 patients (84.4%) by positive bacteriology, in 61 (13.6%) by a favorable response to anti-tuberculosis chemotherapy, and in nine (2.0%) by the presence of a miliary radiographic pattern. Forty (8.9%) patients were HIV-seropositive. AFB-negative smears were found in 14/40 (35.0%) of the HIV-seropositive patients with pulmonary tuberculosis compared with 71/410 (17.3%) of the seronegative patients (risk ratio [RR] = 2.02, 95% confidence interval [CI] 1.26-3.24, P = 0.01). Multivariate analysis revealed that AFB smear negativity was associated with absence of cavitation (P = 0.002), lack of cough (P = 0.005), the presence of HIV seropositivity (P = 0.02), a CD4+ cell count above 200/mm3 (P = 0.02), and age over 40 years (P = 0.03). CONCLUSIONS: Compared with HIV-seronegative patients with pulmonary tuberculosis, seropositive patients in Dakar, Senegal, are more likely to have negative sputum-AFB smears. This phenomenon has now been observed in seven of eight sub-Saharan African countries with varying HIV seroprevalence from which reports are available.

RESUMEN

The Fernand Widal syndrome combines a nasal polyposis, an asthma and aspirin sensitivity. It remains a nosological entity often unrecognized because of the trivialization of aspirin in-take on the one hand the other its etiopathogenesis which has not yet been clarified because of the inhibition of the cyclo-oxygenase. In actual fact the aspirin molecule has yet to reveal all its secrets (advantages and disadvantages). We report 2 cases of Fernand Widal syndrome observed in 2 women in their thirties with a notion of atopy in one at the Pneumophtisiology clinic at the Fann University Hospital in Dakar. The confirmed diagnosis was based on oral provocative test in addition to suggestive clinical signs which emphasize the classical triad with a chronological appearance more or less typical. The best treatment could combine inhaled corticotherapy, nasalization of sinus cavities, antihistaminics, no aspirin in take and educating the patient.

RESUMEN

This study concerns a case-report about a 28 year old Senegalese woman suffering from a SHARP syndrome complicated by a bilateral bacillary pulmonary tuberculosis. The prevalence of this disease is underestimated but a female predominance is often reported. The mechanisms of this disease strongly depends upon the context in with it occurs. The diagnostic has been established by the ALARCON SEGOVIA criteria including clinical symptoms (Raynaud phenomenon, puffy fingers and myalgia) and biological features such as high positive immunofluorescent reactivity revealing the presence of anti RNP antibody at a level superior to 1/1000. The subsequent development figure of the disease emphasizes: persistence of polymyositis pattern revealed by higher limbs localized myalgia involving the thighs and symptoms of lupus including alopecia and glomerulonephritis remaining of the mixed characteristic comparable to the cases published in the literature. appearance of a bilateral bacillary pulmonary tuberculosis with a severe involvement of the right lung. The treatment composed by anti inflammatory and antituberculosis drugs lead to an early improvement of the clinical symptoms associated to a rapid cleaning of radiological manifestations. Sequelae were represented by cavities detected in the right lung and related to the pharmacological effects of corticosteroid drugs.

RESUMEN

A PCR system that amplify a repetitive fragment of the insertion sequence IS6110 specific for M. tuberculosis was compared to direct examination in samples from HIV+ and HIV-patients. 138 clinical samples (90 sputa, 30 blood and 18 urines) were analyzed in Senegal, a tuberculosis and HIV endemic area. All smear positive samples were PCR positive except for 7/138 (5.07%) that were false negative because of the presence of inhibitors. However, the use of several samples for each patient minimize the false negative results. The PCR allowed the detection of more positive results in smear negative sputa from HIV- (50%) than in HIV+ patients (20.5%). In contrast, in smear negative blood samples, PCR was positive more frequently in HIV+ (30%) than in HIV- patients (12.5%). Regarding patients, 15/25 HIV+ and 13/17 HIV-patients had at least one positive sample with PCR whereas only 7/25 and 11/17 respectively for HIV+ and HIV- patients had smear positive samples. Thus with some technical cares, PCR might be a useful tool for rapid diagnosis of M. tuberculosis infection in smear negative samples particularly in HIV+ patients.

RESUMEN

Caerulein administered to anaesthetized pigs by slow i.v. infusions at doses of 0.5, 1.0 and 2.0 ng kg-1 min-1 for 30 min, stimulated pancreatic juice production, increased the protein content of the juice and enhanced its amylolytic, lipolytic and proteolytic activities. In a single experiment, an i.v. infusion of secretin (0.001 U kg-1 min-1) lasting through the whole experimental time, provoked potentiation of the caerulein stimulatory effects on pancreatic juice production, protein content and amylolytic activity.
