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.

Clinical Details

Official title: Early Administration of L-carnitine in Hemodialysis Patients: Double Blind Randomized Trial Versus Placebo

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Factorial Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome:

Resistance index to erythropoietin

Haemoglobin level/weekly rHuerythropoietin dose in patients receiving l-carnitine versus those receiving the placebo.

Secondary outcome:

Acylcarnitine/carnitine ratio measured quarterly

Number of red blood cells transfusion per patient during the study, data collected monthly

Predialysis hypotension per patient during the study, data collected monthly

SF 36 physical and total score at inclusion and at the end of the study

Lipid profile, measured quarterly

HbA1c, measured quarterly for diabetic patients and patients with glucose intolerance

Albuminemia measured quarterly

c reactive protein measured quarterly

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
