Evaluation of the Effects of L-Carnitine Injection in Patients Undergoing Hemodialysis
February 28, 2006 updated by: National Taiwan University Hospital
This is a study designed to test the hypothesis that treatment with L-carnitine will improve the quality of life and some specific symptoms and signs in patients with renal failure submitted to hemodialysis.
Study Overview
Status
Unknown
Intervention / Treatment
Detailed Description
L-Carnitine is a naturally occurring compound that facilitates the transport of fatty acids into mitochondria for beta-oxidation.
A lack of carnitine in hemodialysis patients is caused by insufficient carnitine synthesis and particularly by the loss through dialytic membranes, leading in some patients to carnitine depletion with a relative increase of esterified forms.
Many studies have shown that L-carnitine supplementation leads to improvements in several complications seen in uremic patients, including cardiac complications, impaired exercise and functional capacities, muscle symptoms, increased symptomatic intradialytic hypotension, and erythropoietin-resistant anemia, normalizing the reduced carnitine palmitoyl transferase activity in red cells.

- persistent weakness affecting daily life
- malnutrition
- anemia (hemoglobin [Hb] < 12 g/dl; hematocrit [Hct] < 30%)
- experiencing intradialytic complications (cramping, muscular pain, hypotension, hypertension, head-ache)
