乙肝肝硬化并发皮下脂膜炎样T细胞淋巴瘤伴噬血细胞综合征的治疗分析

目的 探讨乙肝肝硬化并发皮下脂膜炎样T细胞淋巴瘤(SPTCL)伴噬血细胞综合征(HPS)的临床特征和治疗方法。 方法 回顾性分析2014年8月第二军医大学附属东方肝胆外科医院1例乙肝肝硬化并发SPTCL伴HPS病例的临床资料。 结果 T细胞受体(TCR)表型不同则该病的侵袭性、治疗反应性及预后明显不同,伴HPS者治疗效果不佳,生存期短。 结论 乙肝肝硬化并发SPTCL伴HPS罕见,早期骨髓形态学、病理学、免疫组化及基因重排检测对确诊有重要意义,及早有效控制乙肝病毒尤为重要。早期诊断及治疗对延长患者生存期有重要意义。     

IL-12A、IL-1B、IL-17A单核苷酸多态性与慢性乙型肝炎恩替卡韦治疗HBeAg血清学转换的遗传关联研究

目的 通过遗传关联研究观察慢性HBV感染免疫相关重要细胞因子IL-12、IL-1B、IL-17的基因多态性与恩替卡韦抗病毒治疗HBeAg血清学转换之间的关联.方法 对109例恩替卡韦抗病毒治疗的HBeAg阳性慢性乙型肝炎患者每3个月进行肝功能、乙肝标志物、HBV DNA检测,进行HBeAg血清学转换评估,治疗24个月时的应答情况作为判定应答与否的标准.发生HBeAg血清学转换者为应答组;未发生HBeAg血清学转换者为无应答组;分析IL-12A rs568408、IL-1 B rs1143623、IL-17Ars8193036基因型与HBeAg血清学转换之间的关联.结果 29例获得HBeAg血清学转换(应答组),80例未获得HBeAg血清学转换(无应答组),总体应答率26.6％.IL-12A rs568408与HBeAg血清学转换显著相关,GA基因型发生HBeAg血清转换的易感性显著高于GG基因型[OR =3.72(1.34～10.32),P=0.012].未发现IL-1B rs1143623[OR=1.99 (0.72 ～5.44),P=0.17]和IL-17Ars8193036 [OR=1.54 (0.32 ～7.33),P=0.60]与HBeAg血清学转换存在关联.结论 IL-12Ars568408与慢性乙型肝炎恩替卡韦治疗HBeAg血清学转换存在关联.     

复方鳖甲软肝片联合恩替卡韦对肺结核伴慢性乙肝患者肝纤维化的影响

目的探讨复方鳖甲软肝片联合恩替卡韦对肺结核伴慢性乙肝患者肝纤维化的影响。方法选择我院2018年1月至2019年10月收治的60例肺结核伴慢性乙肝患者,根据随机数字表法将其分为对照组和观察组,各30例。两组均实施常规抗结核治疗,在此基础上,对照组给予恩替卡韦,观察组给予恩替卡韦+复方鳖甲软肝片。比较两组的干预效果。结果治疗后,两组患者的血清HA、LN、PCⅢ、Ⅳ-C水平均较治疗前降低,且观察组低于对照组(P<0.05)。观察组的药物性肝损伤发生率低于对照组,病灶吸收率、空洞闭合率、HBV-DNA转阴率及HBeAg转阴率均高于对照组(P<0.05)。结论在肺结核合并慢性乙肝患者的治疗中联合应用恩替卡韦和复方鳖甲软肝片,可降低药物性肝损伤发生率,减轻肝纤维化程度,促使结核病灶吸收、肺部空洞闭合、乙肝病毒转阴。     

Entecavir for the long-term treatment of chronic hepatitis B

Hepatitis B virus is a major cause of chronic liver disease worldwide and is associated with an increased risk of hepatocellular carcinoma, progressive hepatic fibrosis and end-stage liver disease. Suppression of HBV replication is recognized as the primary on-treatment goal of antiviral therapy, as reduction of serum HBV DNA to low or undetectable levels is highly likely to have a positive impact on long-term clinical outcomes in HBV-associated chronic liver disease. Entecavir is an oral nucleoside analogue that effectively inhibits HBV polymerase, resulting in rapid viral suppression. Long-term data on patients receiving entecavir for chronic hepatitis B have demonstrated high potency, a low incidence of antiviral drug resistance and good tolerability, making entecavir an ideal first-line agent for the treatment of chronic hepatitis B.     

Significance of switching of the nucleos(t)ide analog used to treat Japanese patients with chronic hepatitis B virus infection from entecavir to tenofovir alafenamide fumarate

The significance of switching of the nucleos(t)ide analog used to treat patients with hepatitis B virus (HBV) from entecavir (ETV) to tenofovir alafenamide fumarate (TAF) is uncertain. The subjects of this study were 159 patients with HBV who received treatment with ETV followed by TAF. Among these patients, serial changes in the HBV marker levels were monitored in 92 patients in whom the serum HBsAg levels were ≥100 IU/mL during the 48-week period immediately before and after the switching. A questionnaire survey for medication compliance was performed in 127 patients. The serum HBsAg levels (log IU/mL) decreased by 0.041 during the ETV treatment period and by 0.068 during the TAF administration period. The degree of reduction was higher during the TAF administration period than during the ETV administration period in patients without cirrhosis (P = .030), patients with genotype B HBV (P = .014), and patients with undetectable serum HBcrAg (P = .038). Multivariate analysis revealed the HBV genotype (B vs C; odds ratio, 3.400; P = .025) and serum aspartate aminotransferase level (every 1+; 1.111; P = .015) at the time of switching as factors influencing the treatment efficacy. Thirty-six patients (28%) responded that the number of days that they forgot to take the drug decreased after the drug switching, and 77 patients (61%) reported feeling satisfied with the drug switching. Switching of the nucleos(t)ide analog used from ETV to TAF may be useful in the treatment of patients with HBV infection, as it is associated with both a decrease in the serum HBsAg level and improvement of the medication compliance.
