Carnitine nutriture of dialysis patients.
Hemodialysis patients often experience muscle weakness, cardiac arrhythmias, and hypertriglyceridemia, along with other conditions that may lead to atherosclerosis and coronary heart disease. A contributing factor in the etiology of the symptoms may be carnitine deficiency. Patients undergoing renal dialysis treatment are at risk for developing a carnitine deficiency. The small carnitine molecule can be easily lost into the dialysate. A diseased kidney may lead to a decrease in the endogenous supply of carnitine since the kidney is a major site of carnitine biosynthesis. The diet of dialysis patients may be limiting in preformed carnitine as well as in the precursors and micronutrients required for carnitine biosynthesis. Both oral and intravenous supplementation of L-carnitine have been shown to alleviate muscle weakness, reduce the incidence and severity of arrhythmias, and decrease plasma triglyceride levels, along with alleviating other complications noted in dialysis patients. Health care professionals must be aware of the possible benefits of providing carnitine supplementation for renal dialysis patients.
