Filter by:The aim of the study is to create a self-questionnaire to evaluate sodium and potassium diet in chronic kidney disease patients. Questionnaires will be compared to 24h sodium and potassium urinary excretion (reference) A Bayesian network and a multiple regression will be used to select the most relevant items
It has recently been described the presence of a urinary inflammatory signature in patients with cystinuria, the most common cause of renal lithiasis of genetical origin. These data are very innovative in this pathology but deserve further studies to establish the specificity of this inflammatory signature in patients with cystinuria compared to other nephropathies and other renal lithiasis diseases. Moreover, the effect of the usual treatment of cystinuria (namely urine alkalanization) on urinary inflammatory biomarkers deserves to be tested. The objectives of the present study are: i) To study the urinary inflammatory profile by mass spectrometry (a very efficient tool to detect and identify proteins) in patients with cystinuria and in patients with lithiasis of other origin and in patients with inflammatory renal disease ; ii) To study the potential effect of urine alkalinazation with potassium citrate (usual treatment according to European recommendations) on the inflammatory signature of patients with cystinuria. To this aim, urine of non treated cystinuric patients will be collected before treatement initiation and 3 months after the start of the alkalizing treatment.
The purpose of this study is 1. To describe patient characteristics and drug usage among children that are prescribed esomeprazole for the first time and to compare them with patients who are prescribed other proton pump inhibitors (PPIs) or H2-receptor antagonists for the first time. 2. To ascertain all incident hospitalized cases of angioneurotic oedema, pneumonia, gastroenteritis, failure to thrive, convulsions/seizures, acute interstitial nephritis and thrombocytopenia among new users in the three cohorts of esomeprazole, other PPIs and H2-receptor antagonists.
The aim of this study is to identify families with hereditary chronic tubulointerstitial renal diseases , characterize the phenotype and screen for mutations in known genesis (UMOD, REN, TCF2, NPHP1). Genome wide analysis will be performed in families without mutations identified.
