血浆置换治疗重型肝炎的临床观察

目的观察血浆置换(PE)治疗重型肝炎的临床疗效及影响效果的主要因素。方法随机抽取符合病例选择标准的40例患者为治疗组,36例为对照组,两组内科综合治疗相同,治疗组加PE治疗。通过观察两组患者治疗前后临床症状、生化指标等的变化及出院后6个月随访,判断PE的疗效及影响疗效主要因素。结果治疗组治疗后第2、4周ALT、TBIL指标比对照组明显改善(P均<0.01);治疗组急、慢性患者出院时及出院后6个月随访总有效率明显高于对照组(P<0.01或P<0.05);治疗组早、中期患者有效率明显高于对照组(P<0.05);但在晚期,PE治疗组与对照组相比差异无显著性(P>0.05);出现肝性脑病、上消化道出血、肝肾综合征、自发性腹膜炎等并发症时的治疗有效率差异无显著性(P>0.05)。结论PE治疗重型肝炎疗效肯定,肝病严重程度、病期及并发症为影响疗效主要因素,掌握治疗时机是提高疗效的关键。

人工肝支持系统治疗重型病毒性肝炎临床观察

目的探讨血浆置换(PE)治疗重型肝炎的疗效。方法设治疗组和对照组各60例,两组病情差异无显著性(>0.05),两组均按重型肝炎常规检查和治疗。治疗组同时给予PE治疗。结果治疗组与对照组在ALT、AST、TBIL下降,PTA(%)提高,ALB上升等方面差异有显著性(﹤0.05),治疗组效果明显优于对照组。结论人工肝-血浆置换是治疗重型肝炎的方法有效的,不良反应轻微。

Immunogenicity of recombinant hepatitis B vaccine in treatment-nave and treatment-experienced chronic hepatitis C patients: The effect of pegylated interferon plus ribavirin treatment

AIM： To retrospectively evaluate the vaccinationinduced anti-HBs seroconversion rates in treatmentnaive and treatment-experienced chronic hepatitis C （CHC） patients. Also to prospectively evaluate the seroconversion rates in CHC patients during pegylated interferon （PEG） plus ribavirin （RIB） treatment. METHODS： Seventy treatment-naive CHC patients （group A）, 22 sustained virological responders-SVR following interferon （IFN） plus RIB treatment CHC patients （group B） and 121 healthy subjects （group C） had been participated in the same HBV vaccination schedule （20 μg, 0-1-6 mo）. Seroconversion was considered if anti-HBs levels were above 10 mIU/mL within 3 mo following the third dose of the vaccine. Moreover, we prospectively selected 30 non-cirrhotic CHC patients and evaluated them for the efficacy of the same vaccine schedule randomizing them in two groups： Group-1, 15 CHC patients received the first dose of the vaccine in parallel with the initiation of PEG plus RIB treatment and Group-2, 15 patients received the same vaccination schedule without concomitant treatment. Determination of anti-HBs was performed at mo 1, 2, and 7. Statistical analysis of data was based on ANOVA student＇s t-test and chi-square analysis （P 〈 0.05）. RESULTS： Fifty-eight of 70 group A patients （82.85%）, 20/22 group B （90.9%） and 112/121 healthy subjects （92.56%） had been seroconverted. The seroconversion rates were significantly higher in the control group than in treatment-naive CHC patients （P = 0.04）. The corresponding rates were comparable between group A and group B CHC patients （P = 0.38）. The vast majority of non-responders （10/14, 71.43%） had been infected by genotype-1 of HCV. The seroconversion rates were comparable between group 1 and 2 CHC patients at mo 1 （20% versus 26.7%, P = 0.67）, mo 2 （46.7% vs 60%, P = 0.46） and mo 7 （86.7% versus 93.3%, P = 0.54） of follow-up. CONCLUSION： The immunogenicity of HBV vaccine seems to be lower in CHC patients compared to healthy subjects. SVR following IFN plus RIB treatment does not affect the antibody response to HBV vaccine. Infection by genotype-1 seems to negatively influence the seroconversion rates. Vaccination against HBV during PEG plus RIB combination treatment is not beneficial in terms of anti-HBs seroconversion rates.
