Background: Natural human interferon-beta (nIFN-beta) seldom causes neurological adverse effects and is recommended for depressive patients with chronic hepatitis C. It also does not often cause thrombocytopenia, in contrast to pegylated interferon-alpha (PEG-IFN-alpha), which often causes thrombocytopenia. Limited data has been reported comparing nIFN-beta and PEG-IFN-alpha when ribavirin (RBV) is combined. This case-control study was done to compare the efficacy adverse effects of a combination of nIFN-beta or PEG-IFN-alpha plus RBV for chronic hepatitis C patients.

Methods: Sixty patients (42 hepatitis C virus genotype 1 and 18 genotype 2) were treated with nIFN-beta plus RBV (48 week course for genotype 1 and 24 week course for genotype 2). Of them, 23 (38.3%) suffered pre-treatment severe depression. Their data was compared with that of 60 age-, sex-, and genotype-matched patients who were treated with PEG-IFN-alpha plus RBV treatment for the same treatment periods. None of the patients in the PEG-IFN-alpha treated group suffered pre-treatment depression.

Results: Sustained virological response rates did not significantly differ between the nIFN-beta and PEG-IFN-alpha treated groups (genotype 1, 21.4 % vs. 33.3 %, P=0.328; genotype 2, 72.2 % vs. 88.9 %, respectively, P=0.402). None of the nIFN-beta-treated patients showed exacerbation of depression or malaise, but 7 (11.7%) of 60 PEG-IFN-alpha treated patients developed severe malaise. The mean percentage of platelet count decrease from baseline to the week 4 of treatment significantly differed between the nIFN-beta and PEG-IFN-alpha groups (-7.1% vs. -26.2%) (P<0.001). Among patients with a baseline platelet count <120×10⁹/L, the percentage of decrease to <80×10⁹/L at week 4 was significantly lower at 50.0% (14 of 28) of the nIFN-beta-treated group than at 88.9% (8 of 9) of the PEG-IFN-alpha-treated group (P=0.035).

Conclusion: nIFN-beta plus RBV treatment was well tolerated by chronic hepatitis C patients with depression or thrombocytopenia.
