核苷类似物治疗乙型肝炎病毒感染所致慢加急性肝衰竭的短期疗效

目的 探讨核苷类似物治疗对HBV感染所致慢加急性肝衰竭(HBV-ACLF)的短期疗效.方法 将我院2006年1月-2008年6月收治的348例HBV-ACLF患者作为研究对象,根据人组时病情分期及是否应用核苷类似物抗病毒治疗分为4组:早期未治疗组、早期治疗组、中期未治疗组和中期治疗组.统计每组患者4周生存率及病情好转率,并对348例患者2周时及184例患者4周时的总胆红素(TBil)、ALT、凝血酶原活动度(PTA)、终末期肝病模型(MELD)评分等进行组间比较分析.组间计量资料的比较用t检验,率的比较用x2检验,P＜0.05为差异有统计学意义.结果 治疗2周时,早期未治疗组与早期治疗组、中期未治疗组与中期治疗组间,TBil、ALT、PTA和MELD评分差异均无统计学意义(P值均＞0.05).治疗4周时,早期未治疗组与早期治疗组间,TBil、ALT、PTA和MELD评分差异均无统计学意义(P直均＞0.05);中期未治疗组与中期治疗组间,PTA(分别为29.6%±9.6%和25.1%±9.1%)及MELD评分(分别为29.8±9.6和22.1±9.1)差异有统计学意义(t值分别为-3.052和4.069,P值均＜0.05).治疗4周后,早期未治疗组与早期治疗组的HBV DNA转阴率分别为39.0%(16/41)和72.1%(44/61),4周生存率分别为53.4%(39/73)和75.0%(69/92),差异均有统计学意义(x2值分别为17.61和8.38,P值均＜0.01);中期未治疗组与中期治疗组的HBV DNA转阴率分别为42.3%(16/21)和80.4%(45/56)P4周生存率分别为26.1%(24/92)和44.3%(47/106),差异均有统计学意义(x2值分别为10.98和7.13,P值均＜0.01).结论 应用核苷类似物抗病毒治疗可提高患者30 d生存率,是HBV感染所致慢加急性肝衰竭内科有效治疗方法之一; HBV DNA转阴率、PTA及MELD评分可作为观察核苷类似物抗病毒近期疗效指标.

The short-term efficacy of nucleoside analogue on the treatment of acute-on-chronic liver failure

Objective To discuss the short-term efficacy of nucleoside analogue on the treatment of hepatitis B virus induced acute-on-chronic liver failure (HBV-ACLF). Methods 348 patients with HBVACLF in our hospital from January 2006 to June 2008 were selected. According to the stages of patient's condition and whether or not with nucleoside analogue administration, The patients were divided into early stage therapy group, early stage control group, middle stage therapy group and middle stage control group.Groups were compared on the basis of stages. The clinical data were analyzed using chisquare test and independent-Samples T Test. Results After 2 weeks of therapy no significant difference found between the therapy group and the control group. the total bilirubin (TBil) and alanine transarninase (ALT) showed no significant difference between the middle stage therapy group and the control group in 4 weeks of therapy.However significant differences existed in the HBV DNA negtive rate, PTA, the moder for end-stage liver disease (MELD) score and the improvement rate between the two groups (P ＜ 0.05, P ＜ 0.01). Only the 4 week survival rate and HBV DNA negtive rate showed significant difference in patients who received antivirus therapy on the early stage as compared to the control group. Conclusion Anti-virus therapy with nucleoside analogue is an effective way for the treatment of those patients with HBV-ACLF and can increase the survival rate.
