Abstract

Introduction. L-Carnitine is a cardioprotective agent which balances metabolism by promoting mitochondrial β-oxidation and facilitating transportation of long chain fatty acids into the mitochondrial matrix. It has been shown that L-Carnitine level in plasma and tissue is lower in hemodialysis patients and they may lose the benefits of this substance. The aim of this trial was to evaluate the effects of L-Carnitine supplementation on cardiorespiratory Function in hemodialysis patients through ergospirometry. Methods. The current study was conducted on 46 chronic hemodialysis patients. The patients were divided into two groups. In both groups ergospirometry parameters (VE Max, VO2-Max and VCO2 Max, AT, VE/VCO2 Slope) were recorded for a 3-month period of time. During this period, one group received L-Carnitine at doses of 2 g/d orally and the other group received only placebo. After three months, all of the mentioned parameters reevaluated and statistical analysis was done. Results. Only CRP value was different between two group and in placebo group increased significantly after 3 months (P < .05). No significant difference was detected in Cardio-respiratory factors. In terms of ergospirometry, PET-CO2 was the only parameter which was significantly increased in the treatment group but decreased in placebo group (P < .05). Conclusion. Significant differences between our groups showed that L-Carnitine could help hemodialysis patients with cardiopulmonary problems to suffer lower rate of inflammation and poor life quality as shown at least in comparison of the two factors including CRP and PETCO2 at rest.
