To introduce the possible role of hydroxyurea (HU), a well-characterized antineoplastic drug with established antiviral effects, in the treatment of chronic hepatitis B.
Four antiretroviral-naïve patients with chronic hepatitis B were enrolled in this limited pilot trial, and given 1000 mg/day of hydroxyurea for 4 weeks; then, the administration of the drug was suspended for 4 weeks. A clinical study and laboratory safety assessments and measurements of viral load were made at baseline, after drug therapy, and after one month suspension of the treatment
All 4 patients showed a significant decrease in viral load after 4 weeks of hydroxyurea therapy and the viral load of 2 patients increased again after a 4-week suspension of hydroxyurea
Our data demonstrate that the old low-cost antineoplastic drug, hydroxyurea, efficiently blocks hepatitis B virus (HBV) replication. We suggest that HU will play an important role in the treatment of chronic hepatitis in the foreseeable future. Further studies including those that evaluate optimal dosing in long-term use will continue to define the role of HU in the treatment of HBV infection alone or in combination with other antiviral drugs.
介绍羟基脲(HU)这一具有明确特征且已证实具有抗病毒作用的抗肿瘤药物在慢性乙型肝炎治疗中可能发挥的作用。
四名未接受过抗逆转录病毒治疗的慢性乙型肝炎患者参与了这项有限的试点试验,给予他们每日1000毫克的羟基脲,持续4周;然后,停药4周。在基线、药物治疗后以及治疗暂停1个月后进行了临床研究、实验室安全性评估以及病毒载量检测。
所有4名患者在接受4周羟基脲治疗后病毒载量均显著下降,2名患者在停药4周后病毒载量再次上升。
我们的数据表明,古老且低成本的抗肿瘤药物羟基脲能有效阻断乙型肝炎病毒(HBV)复制。我们认为在可预见的未来,羟基脲将在慢性肝炎治疗中发挥重要作用。包括评估长期使用最佳剂量的进一步研究,将继续明确羟基脲单独或与其他抗病毒药物联合治疗HBV感染中的作用。
