ABSTRACT
AIM: To evaluate the efficacy of L-carnitine on alleviating anemia, thrombocytopenia and leukopenia, and minimizing dose reductions in patients with chronic hepatitis C virus (HCV) in treatment with Interferon α (IFN-α) plus ribavirin. METHODS: Sixty-nine patients with chronic hepatitis C were enrolled in the study and divided into two groups. group A (n = 35) received Peg-IFN-α 2b plus ribavirin plus L-carnitine, and group B (n = 34) received Peg-IFN-α and ribavirin for 12 mo. All patients underwent laboratory investigations including: red cell count, hemoglobin, white cell count, platelets, bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and viremia. RESULTS: After 12 mo in group A compared to group B we observed significant differences in AST 108.8 vs 76.8 (IU/L; P < 0.001), ALT 137.9 vs 112.3 (IU/L; P < 0.001), viremia 4.04 vs 2.36 (× 106 copies/mL; P < 0.001), Hb 1 vs 3.5 (g/dL; P < 0.05), red blood cells 0.3 vs 1.1 (× 1012/L; P < 0.001), white blood cells 1.5 vs 3 (× 109/L; P < 0.001) and platelets 86 vs 85 (× 109/L; P < 0.001). The end treatment responders were 18 vs 12 (60% vs 44%) and the non responders were 12 vs 15 (40% vs 50%) [odds ratio (OR) 1.65, 95% CI = 0.65-5.37, P < 0.05]. In group A compared to group B there was a significant improvement of sustained virological response in 15 vs 7 patients (50% vs 25%), while the relapsers were 3 vs 5 (10% vs 18%) (OR 3.57, 95% CI = 0.65-19.3, P < 0.001). CONCLUSION: L-carnitine supplementations modulate erythropoiesis, leucopoiesis and thrombocytopoiesis, and may be useful in patients treated for HCV. L-carnitine treatment offers the possibility of achieving a sustained virological response while preventing overtreatment.
