概括
经过病毒治愈的C型肝炎患者仍然需要对肝细胞癌 (HCC) 进行监测,如果其发病率超过每100人/年0.7人. 这一更新的门值低于以前的指导方针,可以改善该群体的早期HCC检测.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 在瘤学瘤学.
- 卫生经济学 卫生经济学
背景情况:
- 肝细胞癌 (HCC) 监测建议肝炎C患者肝硬化,如果发病率超过1.5每100人年 (PY).
- 在C型肝炎肝硬化或晚期纤维化患者病毒治愈后对HCC监测的成本效益仍然未确定.
- 直接作用抗病毒药物导致越来越多的病毒学治愈的型肝炎患者,他们可能仍然面临HCC的风险.
研究的目的:
- 为了估计HCC发病率值,以便在病毒学上治愈的肝炎C患者中进行成本有效的监测,这些患者患有肝硬化或晚期纤维化.
- 在这个特定的患者群体中为HCC监测提供最新的临床指南.
主要方法:
- 一个基于马尔科夫的微模拟模型被开发来模拟HCC后病毒治疗后的自然历史.
- 纳入了关于C型肝炎自然史,治疗后风险,HCC进展,监测遵守,治疗成本和卫生公用事业的数据.
- 该模型估计了半年监测 (超声波和α-fetoprotein) 变得成本效益的HCC发病率.
主要成果:
- 对于病毒学治愈的肝硬化或晚期纤维化肝炎C患者,如果发病率超过0.7/100 PY (在100,000美元/QALY),HCC监测是具有成本效益的.
- 在这个门上,监视与不监视相比,监视带来了显著的额外寿命.
- 敏感性分析表明,成本效益值一般仍低于之前的每100个PY的1.5指南.
结论:
- 对于成本有效的监测,当代HCC发病率值远低于以前确定的水平.
- 根据这些发现更新临床指导方针可以提高病毒学治愈的型肝炎患者的早期HCC诊断.
- 在这种人群中较低的发病率的情况下,可能需要进行常规的HCC监测.

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Retrovirus Life Cycles
46.3K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...
