概括
在慢性乙型肝炎患者中停止核胺类类似物 (NA) 后,氨酸氨转移酶 (ALT) 的升高与HBsAg血清清除无关. 这表明肝细胞损伤不需要B型肝炎的功能治愈.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 病毒学 病毒学
- 免疫学 免疫学 免疫学
背景情况:
- 慢性乙型肝炎患者在停止使用核胺类同类药物 (NA) 后,往往会出现氨酸氨基转移酶 (ALT) 升高.
- 了解影响NA戒断后结果的因素对于管理慢性乙型肝炎至关重要.
- 乙型HBsAg血清清除是实现功能治愈的关键一步.
研究的目的:
- 为了研究ALT升高和在NA停止后的HBsAg血清清除之间的关系.
- 为了确定停止后的肝炎是否预测了成功的HBsAg损失.
主要方法:
- 一项多中心队列研究分析了停止NA治疗的患者.
- 资格标准包括无法检测到的HBVDNA和停产前负的HBeAg.
- 竞争风险分析和时间依赖模型被用于评估HBsAg血清和ALT升高.
主要成果:
- 在841名患者中,38名患者在平均3.7年的随访期间实现了HBsAg血清清除.
- 在10年内,HBsAg血清清除的累积发病率为12.4%.
- 在获得HBsAg血清清除 (93U/L) 的患者中,高峰ALT水平明显低于未获得HBsAg血清清除 (127U/L) 的患者;然而,在多变量分析中,肝炎爆发与血清清除没有显著关联.
结论:
- 在NA停止后ALT升高与实现HBsAg血清清除无关.

271
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Phase II biotransformation reactions are essential for detoxifying and eliminating xenobiotics, including many pharmaceutical compounds. These reactions typically involve conjugation, the covalent attachment of polar endogenous groups such as glucuronic acid, sulfate, methyl, or acetyl moieties to functional groups introduced during Phase I metabolism. The resulting conjugates are more water-soluble, enabling efficient renal or biliary excretion.The major classes of Phase II enzymes include...

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.
