RESUMEN
Background: Patients with chronic hepatitis C are at increased risk for hyperferritinemia (HF). Abnormalities of serum iron parameters are frequently observed in patients with chronic hepatitis C (CHC). About a third of patients have increased iron parameters. Recently, studies on the effect of direct-acting antiviral agents (DAAs) in HCV eradication in patients with increased serum iron has been published, demonstrating the restoration of normal iron status. The aim of this study was to evaluate the effect of viral eradication with DDAs in patients with CHC and HF. Methods: Retrospective study conducted from January 2018 to December 2020 including patients treated with DAAs for HCV. Pre-treatment (PreT) and post-treatment (PostT) serum ferritin values were evaluated in all patients. Inclusion criteria: Pret HF (>400 µg/L); CHC patients treated with DAA achieving sustained viral response (SVR). Exclusion criteria: No PreT or PostT HF available; no SVR; lost patients. Results: From 621 patients treated with DAAs for CHC, 77 presented HF (12.40%), and 74 were included in the study. Fifty nine were men (79.73%) with a mean age 58.33, SD 8.68; PreT mean ferritin: 893.20 (SD 1037.09); PostT: 264.17 (SD 161.33); PreT mean transferrin saturation: 40.96 (SD 15.71); PostT: 29.82 (SD 11.17); PreT mean serum iron 152.32 (SD 62.07), PostT: 109.32 (SD 39.49). When we compared PreT and PostT iron parameters, significant statistical differences were present considering ferritin (p = 0.0000), transferrin saturation (p = 0.0000), and iron (p = 0.0002) determinations. Conclusions: SVR after DAAs for CHC induces a statistically significant reduction on iron parameters.
