Serum free and esterified carnitine levels as well as lipids were investigated in patients undergoing regular hemodialysis (HD) treatment before and during 12 weeks of treatment with L-carnitine (1 g i.v.) at the end of each HD. The results were compared with those obtained in patients on continuous ambulatory peritoneal dialysis (CAPD; n = 15) or intermittent peritoneal dialysis (IPD; n = 3) and healthy controls (CO; n = 20). In HD patients (n = 23) total carnitine (TC) was 49.9 +/- 3.9 (CO: 46.0 +/- 2.5; NS), free carnitine (FC) was 31.6 +/- 2.8 (CO: 37.4 +/- 1.3; p less than 0.05), short-chain acylcarnitine (SCC) was 17.0 +/- 1.8 (CO: 7.2 +/- 0.9; p less than 0.0001) and long-chain acylcarnitine (LCC) was 1.2 +/- 0.2 mumol/l (CO: 0.6 +/- 0.1; p less than 0.05). FC was in the normal range in CAPD (35.6 +/- 3.2) and IPD (44.5 +/- 8.0 mumol/l) patients, whereas SCC (30.1 +/- 3.5) and LCC (2.9 +/- 0.2) levels were maximal elevated in IPD patients (11.8 +/- 0.8 and 1.5 +/- 0.2 on CAPD). Therefore, TC was higher in IPD than in CAPD patients (77.5 +/- 5.0 vs. 49.0 +/- 3.5 mumol/l). 12 weeks after L-carnitine supplementation in HD patients, TC was 313.9 +/- 22.6, FC was 207.7 +/- 12.4, SCC was 99.6 +/- 12.1 and LCC was 7.1 +/- 0.6 mumol/l. TC and FC were significantly lower in females compared with males. Total cholesterol and ketone bodies were normal, HDL cholesterol was significantly decreased before and after L-carnitine supplementation.(ABSTRACT TRUNCATED AT 250 WORDS)
