Insuffisance rénate chronique: attitudes et pratiques de dépistages en l'absence d'etudes randomisées. [Chronic kidney disease: screening attitude and practice in the absence of randomized controlled trials].

Au vu de l'augmentation de la prévalence de l'insuffisance rénale chronique (IRC), une détection précoce a été proposée. Certaines organisations de santé proposent des mesures de détection précoce (par exemple : taux de filtration glomérulaire). L'efficacité du dépistage de l'IRC n'est cependant pas connue puisqu'aucune étude randomisée contrôlée n'a été conduite. Si le test de dépistage de l'IRC est simple et peu onéreux, un dépistage n'est justifié que s'il améliore le pronostic par rapport à l'absence de dépistage avec un rapport risques-bénéfices favorable et un rapport coût-efficacité acceptable. Sur la base d'études observationnelles et de modèles de rapport coût-efficacité, le dépistage de l'IRC doit être proposé chez les patients hypertendus et/ou diabétiques mais pas dans la population générale. [Abstract] Given the increasing prevalence of chronic kidney disease (CKD), early detection has been proposed. Some organizations recommend CKD screening. Yet, the efficacy of CKD screening is unknown given the absence of randomized controlled trial conducted so far. While CKD screening tests (e.g., glomerular filtration rate) are simple and inexpensive, CKD screening can only be justified if it reduces CKD-related mortality and/or CKD-related morbidity compared to no screening. In addition, CKD screening must provide more benefits than risks to the participants and must be cost-effective. Based on observational studies and cost-effectiveness models, CKD screening has to be proposed to high risk population (patients with hypertension and/or diabetes) but not to the general population.

Pseudomonas aeruginosa et maladie broncho-pulmonaire chronique obstructive [Pseudomonas aeruginosa in chronic obstructive pulmonary disease].

The role of Pseudomonas aeruginosa isolated in sputum cultures from adults with obstructive chronic pulmonary disease (COPD) is not well known. However, this pathogen has many factors of virulence and is responsible for several clinical manifestations in this setting. Isolation of a new strain of Pseudomonas is associated with a significant risk of exacerbation of the COPD and its prevalence depends on the severity of the COPD. The role of Pseudomonas among patients with COPD apart from exacerbations is less clear, but it could be responsible for an ignition for the airways and progression for the disease. Currently, the relevance of a prophylactic antibiotic therapy has not yet been demonstrated in COPD holders of Pseudomonas.

Traitement chronique de l'hypertension arterielle par un inhibiteur de l'enzyme de conversion de l'angiotensine. [Chronic treatment of hypertension by an inhibitor of angiotensin converting enzyme]

Captopril, or SQ 14,225 an orally active inhibitor of angiotensin-converting enzyme, produced a significant blood pressure reduction in 26 hypertensives. This new drug, alone or combined with a diuretic, has normalized the blood pressure of the 22 patients on long-term treatment.
