[Can the treatment with L-carnitine improve the inflammation in chronic hemodialysis patients?].

PURPOSE: Inflammation in patients on chronic hemodialysis (HD) is related to malnutrition and atherosclerosis; anemia is also often present in these patients. It has been demonstrated that l-carnitina treatment, in addition to reducing the need for erythropoietin (EPO), improves nutritional parameters and cardiac performance. METHODS: To evaluate the effect of l-carnitine on the inflammatory pathology in patients on chronic HD, we studied 11 patients with no sure signs of malnutrition, flogistic and infective pathologies and with C-reactive protein (CRP) <2 mg/dL. We evaluated at baseline, after 6 and 12 months CRP, serum albumin, hemoglobin (Hb),nPCR and EPO weekly requirement. RESULTS: We observed a reduction in CRP (from 0.88 +/- 0.65 to 0.42 +/- 0.17 mg/dL after 6 months and to 0.50 + 0.36 mg/dL after 12 months), an increase in serum albumin (from 10.9 +/- 1.23 to 2.08 +/- 1.88 and to 11.8 +/- 1.15 g/dL) and an increase in nPCR (from 0.96 +/- 0.09 to 1.15 +/- 0.2 and to 1.16 +/- 0.18 g/kg/die); EPO weekly requirement decreased (from 7363 +/- 2941 to 5909 +/- 3207 units after 6 months and to 5363 +/- 3139 units after 12 months). CONCLUSION: These results seem to underline a positive effect of l-carnitine on the inflammatory pathology of patients on chronic hemodialytic treatment.
