Abstract

Objectives. In short-term observations, interferon (IFN) therapy has been shown to be effective in producing both biochemical and virological responses in children with chronic hepatitis B virus (HBV) infection. However, in long-term follow up, no studies have shown a clear advantage of IFN therapy during childhood. We conducted a retrospective study on the sustained effect of IFN therapy among a Japanese pediatric population. Methods and subjects. A retrospective study was performed on 155 children with chronic HBV infection who were followed in two affiliated hospitals during the period from 1986 to 2013. Results. The 155 patients comprised 97 males and 58 female. Infection route was maternal transmission in 96/155 patients. HBV genotype was A in 17, B in 6, and C in 51 patients. IFN therapy was performed in 48 patients. One year after the completion of IFN therapy, normalization of alanine aminotransferase (ALT) and lower viral levels (<104 copies/ml) was observed in 43 and 29 patients, respectively. The sustained effects of IFN therapy were evaluated by comparison between 43 hepatitis B e-antigen (HBeAg)-positive patients treated with IFN and 67 patients with chronic hepatitis B observed without IFN therapy. A Cox’s proportional hazard analysis showed a higher seroconversion rate in the IFN group than in the untreated group (p = 0.003). Similarly, there were higher rates of ALT normalization and lower viral levels in the IFN group than in the untreated group (p = 0.001 for both). Conclusion. IFN therapy showed sustained effects for achieving ALT normalization and HBeAg seroconversion and for reducing the viral load in children with chronic hepatitis B.

抽象

目标。在短期观察，干扰素（IFN）治疗已被证明是有效的生产在儿童慢性乙型肝炎病毒（HBV）感染生物化学和病毒学反应。然而，在长期随访，没有研究显示儿童时期IFN治疗的明显的优势。我们对干扰素治疗的日本小儿科人口的持续性的影响进行了回顾性研究。方法和科目。 155儿童慢性HBV感染谁随访中两所附属医院期间，1986年至2013年业绩进行回顾性研究。在155例包括97名男性和58女。感染途径是一百五十五分之九十六患者母亲传染。 HBV基因型为A 17，B 6，和C在51例。在48例患者进行干扰素治疗。一年完成干扰素治疗，谷丙转氨酶（ALT）和较低的病毒水平正常化后（<104拷贝/ ml），观察在43和29例，分别为。干扰素治疗的持续作用43乙型肝炎e抗原（HBeAg）阳性阳性与干扰素治疗，67例慢性乙型肝炎无干扰素治疗观察患者之间的比较进行了评价。的Cox比例风险分析，表现出较高的血清转换率干扰素组比未治疗组（P = 0.003）。同样，有ALT复常率较高和较低的病毒水平干扰素组比未治疗组（P = 0.001两者）。结论。 IFN治疗持续显示效果实现ALT复常和HBeAg血清学转换和减少小儿慢性乙型肝炎病毒载量

意思是说儿童感炎乙肝，从少年到青壮年一个长跨度时间段持续干扰素治疗三两次全疗程后均可以安全有效实现DNA低量？或更好效果？

回复 zgct 的帖子

意思是说儿童感炎乙肝，从少年到青壮年一个长跨度时间段持续干扰素治疗一次全程后均可以安全有效实现DNA低量？或更好效果？

不是100%, 比较无干扰素治疗, e血清转换率, ALT正常, DNA低量 更好.

需要阅读整篇文章来了解详情.

咬牙硬挺

嗯，看过骆抗先博客说儿童干扰效果更好
