Having this evidence s , the potential role of Carnitine in improving malnutrition consequences in CKD patients would be clearly defined
Protein energy malnutrition is a common problem in patients with chronic kidney disease ( CKD ) .
Scattered reports indicate that supplementation of Carnitine may improve patients ' clinical symptoms , with significant improvement in nutritional parameters .
This systematic review was done to document the evidence s of Carnitine effects in nutritional status of CKD patients .
Nutritional effects of carnitine supplementation in hemodialysis patients.
AIMS Carnitine is involved in fatty acid metabolism and it is cleared by dialysis . As it plays a role in energy utilization and because malnutrition is a frequent complication of HD treatment , we studied the effects of carnitine supplementation on several nutritional parameters in HD patients . MATERIAL AND METHODS The main selection criterion was a body mass index ( BMI ; body weight/(height)2 ) < 22 kg/m2 . Fifty-three patients were enrolled to participate in this open and r and omized study . For 6 months , 28 patients received 15 mg/kg of intravenous L-carnitine at the end of each  hemodialysis ( HD ) treatment  ( Group A ) , the remaining 25 patients were controls ( Group B ) . The measured parameters were the post-dialysis body weight , serum albumin concentration ( nephelemetry ) , food intake assessed by a 3-day food question naire , nPNA ( normalized protein equivalent of nitrogen appearance ) , creatinine generation , and anthropometry . RESULTS Forty-five patients completed the study ( Group A : 14 F/9 M , 66.7 years old ; Group B : 11 F/11 M , 65.2 years old ) . At the beginning of the study , there were no differences between the groups for age , gender , HD duration , BMI , diabetes prevalence , plasma carnitine levels and measured nutritional parameters . 65.2 % and 77.3 % in each group were carnitine-deficient ( plasma total carnitine level < 35 micromol/l ) . After 6 months of L-carnitine supplementation , none of the nutritional parameters had changed in either group , except that serum albumin concentration decreased in both groups . Dividing each group according to their respective median serum albumin concentrations , daily energy and protein intakes , creatinine generation or triceps skinfold thickness did not show any difference in the various nutritional parameters with or without carnitine supplementation . CONCLUSION Carnitine supplementation , despite normalization of plasma carnitine levels , has no effect on the nutritional status of HD patients
