Viral hepatitis: Past,present, and future

Each hepatitis virus—Hepatitis A, B, C, D, E, and G—poses a distinct scenario to the patient and clinician alike. Since the discovery of each virus, extensive knowledge regarding epidemiology, virologic properties, and the natural clinical and immunologic history of acute and chronic infections has been generated. Basic discoveries about host immunologic responses to acute and chronic viral infections, combined with virologic data, has led to vaccines to prevent Hepatitis A, B, and E and highly efficacious antivirals for Hepatitis B and C. These therapeutic breakthroughs are transforming the fields of hepatology, transplant medicine in general, and public and global health. Most notably, there is even an ambitious global effort to eliminate chronic viral hepatitis within the next decade. While attainable, there are many barriers to this goal that are being actively investigated in basic and clinical labs on the local, national, and international scales. Herein, we discuss pertinent clinical information and recent organizational guidelines for each of the individual hepatitis viruses while also synthesizing this information with the latest research to focus on exciting future directions for each virus.     

益气养阴解毒方联合环磷腺苷葡胺注射液治疗病毒性心肌炎35例

目的:探讨益气养阴解毒方联合环磷腺苷葡胺注射液对病毒性心肌炎患者心功能及外周血清肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)、转化生长因子-β1(transforming growth factor-β1,TGF-β1)和干扰素-γ(interferon-γ,IFN-γ)水平的影响。方法:将70例病毒性心肌炎患者按照随机数字法分为对照组和观察组,每组各35例。两组患者均给予常规治疗,对照组在常规治疗的基础上给予环磷腺苷葡胺注射液静脉滴注,观察组在对照组的基础上联合益气养阴解毒方治疗。比较两组患者的临床疗效及治疗前后左室短轴缩短分数(left ventricular shortening fraction,LVFS)、左心室射血分数(left ventricular ejection fraction,LVEF)、心脏指数(cardiac index,CI)、TNF-α、TGF-β1和IFN-γ水平。结果:观察组有效率为88.57%,对照组有效率为68.57%,两组患者有效率比较,差异有统计学意义(P<0.05)。两组患者治疗后LVEF、LVFS高于本组治疗前,且观察组高于对照组,差异具有统计学意义(P<0.05)。两组患者治疗后TGF-β1、TNF-α水平低于治疗前比较,IFN-γ高于治疗前,且观察组TGF-β1、TNF-α低于对照组,IFN-γ高于对照组,差异均有统计学意义(P<0.05)。两组患者不良反应发生率比较,差异无统计学意义(P>0.05)。结论:益气养阴解毒方联合环磷腺苷葡胺注射液治疗病毒性心肌炎疗效更显著,可减轻机体的炎症反应,恢复患者心功能。     

左卡尼汀治疗心肌炎的临床效果与安全性观察

目的对心肌炎患者采用左卡尼汀治疗的效果和安全性进行探究。方法研究对象以2018年7月-2019年9月收治的心肌炎患者82例为对象,以随机数字表划分为常规组和研究组,两组患者每组41例。采用常规治疗方式对常规组进行治疗,在此基础上,采用左卡尼汀对研究组进行治疗。在治疗结束后,观察并比较临床疗效和用药过程的安全问题。结果研究组的治疗总有效率为97.6%,但常规组的治疗总有效率只有80.5%,从结果来看研究组的治疗有效率更高,效果更佳突出,组间结果差异对比(P <0.05)。在不良反应方面,研究组的不良反应(4.9%)虽然比常规组(2.4%)更高,然而从统计学结果来看差异无统计学意义(P> 0.05)。结论针对心肌炎患者采用左卡尼汀进行治疗具有很好的效果,而且具有很高的安全性。
