Abstract
Objective: An evaluation of serum free carnitine level in CAPD patients in relation to dietary intake, nutritional status and CAPD adequacy and duration.
Study design: Food diaries, nutritional (total body mass, lean body mass, serum level of proteins, carnitine, cholesterol) and adequacy (Kt/V, PCR, tCcr, EN) parameters were obtained in 23 CAPD patients.
Results: Normal carnitine level (41.8±6.7 µmol/l) was found in 17 patients being on CAPD through 11.1±9.6 months, whereas in 6 persons treated with CAPD through 9.7±4.1 months carnitine level was 25.4±5.7 µmol/l. Significant differences between low and normal carnitine groups were in tCcr (82.7±16.7 v. 65.9±13.2 l/wk/1.73 m2 BSA), effluent volume (10.9±0.8 v. 9.9±1.5 l/day), effluent glucose concentration (729=167 v. 530±220 mg/dl) and serum globulin level (22.6±6.4 v. 29.3±4.4 g/l). Significant correlation coefficients (for n=23) were found between serum carnitine level and effluent volume (r=−0.509) or plasma globulin level (r=+0.522).
Conclusion: Patients with higher CAPD adequacy show lower serum free carnitine levels and this is related to higher effluent volumes.
