혈액투석을 받는 만성 신부전 환자에서 L-carnitine 의 임상적 효과

Previous studies have reported conflicting results of carnitine supplementations on plasma lipids, clinical and biochemical effects in patients with chronic renal failure. We therefore performed a double-blind placebo controlled trial to evaluate the effects of post- hemodialysis intravenous injection of L-carnitine in ESRD patients on maintenance hemodialysis. The trial which lasted two months (baseline, 2 months treatment) was double blind placebo controlled and randomized. Thirty longterm hemodialysis patients, were given carnitine (n=15) or placebo (N=15), completed this study. In each group, clinical lipid and biochemical parameters during treatment were compared with baseline values. Fifteen patients received up to 2 months of L-carnitine infusion ($gt;50 kg; 1.5 g, $lt;50 kg; 1 g) and 15 received placebo infusion (0.9% normal saline). The results were as follows: 1) There were no significant changes observed in plasma triglyceride, HDL-cholesterol or other lipoprotein parameters except free fatty acid in either the carnitine or placebo treated group, Free fatty acid decreased signifiantly in the carnitine treated group (p $lt; 0.005). 2) Intradialytic hypotension and muscle cramp were reduced only in the carnitine treated group (p$lt;0.05). 3) No significant change was observed in serum urea nitrogen, creatinine or inorganic phosphorus in the car- nitine or placebo treated groups. 4) Mid-arm circumference and triceps skinfold thick- ness were measured in all patients. No significant changes in any of these variables were noticed in either carnitine or placebo treated group. In conclusion, intravenous L-carnitine in hemodialysis patients appear to be associated with decrease in dialytic symptoms, sense of well-being and free fatty acid, not associated with any major effects on other lipid profiles.
