 这个研究结果令人吃惊!其一,疗效十分理想,26.7%(38/147)患者出现HBsAg血清转换(注:S抗原转换难度远远超过E抗原转换,换句话说,比现在所谓的乙肝疫苗强多了),而且随访时间比较长,这是很关键的指标,否则仅仅短期清除乙肝病毒,或实现病毒滴度下降,都无法防止未来继续复发或加重的可能。而长时是随访,而且是S抗原的转换,其疗效是令人欣喜的。不过,从摘要中还没有看出E抗原血清转换率有多高?继续关注全文。

近日,来自北京佑安医院的学者在杂志 Journal of Gastroenterology and Hepatology(IF 2.41 2010发表了他们在乙型肝炎研究上的最新研究成果,相关文章于11月18日发表在该杂志上。

乙型肝炎的临床缓解乃至治愈,是多少乙肝患者的梦想,也是广大临床工作者追求的最终目标。北京佑安医院的学者近期进行了一项对于乙肝e抗原(HBeAg)阳性的慢性乙型肝炎患者应用α-干扰素联合核苷(酸)类似物治疗,延长疗程的最终效果。该研究得出结论:两药联合应用并延长疗程的方法,是实现高HBsAg清除率的一个有效的方法。乙肝表面抗原(HBsAg)清除是乙型肝炎最接近治愈的一个指标,此次研究的目的旨在研究α-干扰素与核苷(酸)类似物联合治疗后达到HBsAg血清学转换的慢性乙型肝炎患者的临床特点。

该次研究为一项回顾性研究,招募了2001年6月至2009年5月期间共142名慢性乙型肝炎患者,其中38例采用α-干扰素加核苷(酸)类似物治疗,并达到HBsAg血清学转换的慢性乙型肝炎患者。每3个月收集患者治疗前后的临床和实验室数据。(这项研究中所有达到HBsAg血清学转换的患者治疗后最少随访12个月)。

研究结果显示,142例患者中38例在采用α-干扰素和核苷(酸)类似物延长治疗后(中位疗程31个月)实现HBsAg血清学转换。 实现HBeAg血清转换和HBsAg血清转换的平均时间分别为19.5个月(3-60个月)和25.5个月(9-63个月)。 36例(95%)在治疗后的随访期间仍保持HBsAg血清学转换。研究中观察到3种不同的HBsAg反应模式:经典模型组中57.9%(22 / 38 例),同步转换模型中23.7%(9 / 38例),HBsAg早期转换模型中18.4%(7 / 38例)。(生物谷Bioon.com)

Background and aims: HBsAg clearance is the closest cure outcome in hepatitis B. The goal of this study is to investigate clinical features in chronic hepatitis B patients achieving seroconversion of HBsAg after treatment with interferon alpha and a nucleos(t)ide analogue. Methods: This retrospective study enrolled thirty-eight chronic hepatitis B patients treated with interferon alpha plus a nucleos(t)ide analogue and achieved HBsAg seroconversion during the period from June 2001 to May 2009. Clinical and laboratory data of the patients were collected before and after treatment every 3 months. All patients with HBsAg seroconversion in this study were followed up at least 12 months post-treatment. Results: 38 out of 142 patients achieved HBsAg sercovertion after treatment with interferon alpha and a nucleos(t)tid analogue for prolonged period of time(medium 31 months). The median time to HBeAg seroconversion and to HBsAg seroconversion was 19.5 months (range 3-60 months) and 25.5 months (range 9-63 months) respectively. Thirty-six patients (95%) sustained HBsAg seroconversion during the post-treatment follow-up. Three different HBsAg response patterns were observed with classical model accounting for 57.9% (22/38 cases), simultaneous transition mode accounting for 23.7% (9/38 cases), and HBsAg prior transition model accounting for 18.4% (7/38 cases). Conclusions: Extended treatment with interferon alpha in combination with a nucleos(t)ide analogue in patients with HBeAg-positive appears to be a promising approach for achieving high rate of HBsAg clearance - the closest outcome to cure.
