{diamondsuit} Objective: In the present study, we aimed to determine levels of free carnitine in hemodialysis (HD) and peritoneal dialysis (PD) patients in India and to correlate carnitine deficiency with various clinical parameters.

{diamondsuit}Methods: Patients on HD and PD at two tertiary care centers were selected for the study. Baseline data were obtained, and a free carnitine analysis was performed. Carnitine deficiency was defined as a free carnitine level of less than 40 µmol/L.

{diamondsuit}Results: The total number of study patients was 96 (77 on HD, 19 on PD). In the PD group, the mean age was 56 years, with 26.3% of the patients being vegan, 47.4% having diabetes, and 57.9% having a daily urine output of <500 mL. The mean carnitine level in that group was 38.9 µmol/L, and 68.4% of the patients had a carnitine deficiency. A Pearson correlation test failed to show any association of carnitine level with parameters such as anemia, use of erythropoietin, non-vegetarian diet, diabetes, and hypertension. In the HD group, the mean age was 45 years, with 22% of the patients being vegan, 23% having diabetes, and 45.5% having a daily urine output of <500 mL. The mean carnitine level in the group was 38.2 µmol/L, and 64.3% of the patients had a carnitine deficiency. Residual renal function and duration of dialysis were different in HD patients with and without carnitine deficiency. Carnitine levels in the HD group correlated positively and statistically significantly with the presence of diabetes and hypertension.

{diamondsuit}Conclusion: This study is the first demonstration that Indian dialysis patients have carnitine deficiency.

KEY WORDS: Carnitine deficiency; CAPD; hemodialysis; anemia; residual renal function.
