title: Chronic hepatitis C in elderly patients: clinical, histological and virological features.
abstract: Some clinical, histological and virological features, efficacy and safety of interferon (IFN) therapy were evaluated in elderly patients with chronic hepatitis C (CHC). We enrolled 22 patients aged 65-75 (mean age: 68.3 +/- 3.17 years); 15 males and 7 females. In all cases the hepatitis C virus RNA (HCV-RNA) was determined before, during and after the therapy, and HCV sub-types were established; 15 patients underwent hepatobiopsy. At entry, the duration of disease was: 6 patients 1-3 years, 2 patients 4-10 years, 14 patients 11-30 years; alanine-aminotransferase (ALT) = (3.17 +/- 1.15) x N (N = normal value); aspartate-transaminase (AST) = 2.28 +/- 1.6 x N; gamma-glutamyl-transpeptidase (gGT) = 1.4 +/- 1.1 x N; platelets = 164,000 +/- 66,000/mm(3); histological pattern: 2 mild chronic active hepatitis (CAH), 5 CAH, 2 severe CAM, 6 CAH with liver cirrhosis (LC); histological activity index (HAI) (14 patients) = 11.14 +/- 4.5 (range 5-17); scores according to Scheuer: lobular 2.28 +/- 1.13, portal 2.71 +/- 0.99, fibrosis 2.35 +/-1.33; HCV-RNA +ve: 20 patients, HCV-RNA -ve: 2 patients; HCV-subtypes: 1b 20/20 (100%), 1b+1a 1/20 (5%), 1b+ 2a 1/20 (5%). Treatment was applied to 18 patients, for 3-12 months; 5 received alpha-IFN2a; 5 received alpha-IFN2b, 3 lymphoblastoid IFN, all at a dose of 3 mU thrice per week; 3 patients received 6 mU beta-IFN thrice per week. Therapy over 6 months was applied to 16 patients: Complete response (CR) was observed in 8 patients (50%), one of them was with long-term CR (over 12 months after therapy); 5 have had relapse and 2 patients are still under treatment. Partial response (PR) was observed in 4 patients (25%), no response (NR) in 4 patients (25%). Side effects were moderate and self-limited. Loss of HCV-RNA was shown in some patients with PR and in all patients with CR, but only temporarily.
