In a long-term study (27 months) of patients affected by C-virus active hepatitis we have evaluated the effect of decreasing the dose of interferon by 50% and by 75% with respect to the initial efficacious dose (6 MU tiw). Sixty patients received recombinant interferon alpha-2b(r-IFN- alpha-2b) 6 MU tiw for two months followed by 3 MU for seven months (Group A), and 60 patients received r-IFN alpha-2b 6 MU tiw for two months followed by 1.5 MU for seven months (Group B). Three patients in group B failed to return to follow-up and were not considered in subsequent evaluations. Side effects such as to cause suspension of treatment occurred only during the first two months of the study at 6 MU of interferon (3 patients in group A and 6 in group B). During the two months at 6 MU, transaminase values returned to normal in 94 patients (80%). At the end of follow-up, 49 of these patients (42% of the 117 patients examined; or 48.3% in group A and 35.1% in group B) had normal transaminase levels. In no case did the anti-HCV test become negative. On a reduced dose of interferon, relapses occurred more frequently in group B (21.4%) than in group A (9.6%), but the difference was not significant. No difference between responders and non-responders, including relapsing patients, was observed in relation to gender, age, presence of cirrhosis, presence of B-virus antibodies and initial levels of serum transaminase.
在一项针对丙型肝炎活动性肝炎患者的长期研究(27个月)中,我们评估了相对于初始有效剂量(6MU,每周三次)将干扰素剂量降低50%和75%的效果。60名患者接受重组干扰素α-2b(r-IFN-α-2b)6MU,每周三次,持续两个月,随后7个月接受3MU(A组),60名患者接受r-IFNα-2b 6MU,每周三次,持续两个月,随后7个月接受1.5MU(B组)。B组有3名患者未返回接受随访,后续评估未将其纳入。仅在研究的前两个月,当干扰素剂量为6MU时,出现了导致治疗中断的副作用(A组3例,B组6例)。在6MU治疗的两个月期间,94名患者(80%)的转氨酶值恢复正常。随访结束时,这些患者中有49名(占检查的117名患者的42%;A组为48.3%,B组为35.1%)转氨酶水平正常。抗-HCV检测在任何情况下均未转为阴性。在较低剂量的干扰素治疗下,B组(21.4%)的复发频率高于A组(9.6%),但差异不显著。在应答者和无应答者之间,包括复发患者,在性别、年龄、肝硬化的存在、B病毒抗体的存在以及血清转氨酶的初始水平方面未观察到差异。
