5. Study Description

Brief Summary
Hemodialysis is a cause of carnitine deficiency. The deficiency of carnitine induces an anemia by an increase fragility of the red blood cells, a muscular fatigue and a cardiac dysfunction. We proposed to evaluate the benefit of an early administration of L-carnitine in hemodialysis patients. The patients should be included in the first month after the start of chronic hemodialysis, randomized to receive L-carnitine or placebo and should be followed-up during one year.
Detailed Description
The first aim of the study is to compare the resistance index to erythropoietin (hemoglobin level / rHuerythropoietin dose) with L-carnitine versus placebo Double blind randomized study evaluating the supplementation with L-carnitine versus placebo in patients beginning chronic hemodialysis for less than 1 month. Primary outcome to compare rHuerythropoietin resistance index defined as hemoglobin level / rHuEPO dose ratio with L-carnitine and with placebo. Secondary endpoints to compare acylcarnitine / carnitine ratio, number of red blood cells transfusion, physical status, quality of life, hypotensive episodes, lipid profile, diabetes profile, albuminemia, c reactive protein. Several variables that influenced primary and secondary endpoints will be included in a multivariate analysis; albuminemia, c reactive protein, iron status, dialysis efficiency, protein intake, lipid intake, treatment with additional vitamins (C, B9, B6), treatment with statins, treatment of predialysis hypotension by midodrine, antihypertensive treatments. Statistical analysis: description of the cohort comparisons of each evaluated variables between the 2 treatments ANOVA study for repeated measurements from inclusion to month-12 for Hb / rHuEPO dose to compare the course of the ratio between each group in intention to treat analysis analysis of the ratio Hb / rHuEPO month by month and taking into account tempera withdrawal Following analysis in both intention to treat and per protocol analysis: acylcarnitine / carnitine ratio by ANOVA for repeated data number of predialysis hypotension by Chi2 test number of red blood cells transfusion by Chi2 test SF-36 physical status by comparison of mean SF-36 total score by comparison of mean lipid profile by ANOVA for repeated data HbA1c by ANOVA for repeated data variables that influenced primary and secondary variables will be analyzed by multivariate analysis statistical study of clinical events per month
