Abstract

Elderly patients with chronic hepatitis C have a reduced responsiveness to antiviral therapy with Peg-interferon and ribavirin. The dose reduction or the discontinuation of ribavirin due to the occurrence of anaemia is one of the most important causes for the low sustained viral response observed in older patients. We aimed to evaluate the relationship between baseline renal function and the early onset of ribavirin-associated anaemia in older (≤yen;60 years) patients. Using data from 348 patients with chronic hepatitis C consecutively treated with peg-interferon plus ribavirin, we investigated which factors were associated with the occurrence of anaemia in elderly patients (≤yen;60 years). Ribavirin-induced anaemia occurred in 40.5% of patients. Older patients showed a rate of anaemia significantly higher than younger patients (51.5% vs 36.3%; P = 0.009). Consequently, the rate of ribavirin dose reduction or discontinuation due to anaemia was 35.1% in older patients and 23.5% in younger patients (P = 0.029). A significantly higher proportion of older patients had a low baseline glomerular filtration rate (GFR) compared with younger patients (56.7% vs 27.1%; P <0.001). At the multivariate regression analysis, low baseline GFR (60 years, a low pre-treatment GFR was strongly associated with the risk to develop ribavirin-related anaemia with consequent reduction in ribavirin doses.
