概括

这项研究揭示了性肝病 (SLD) 现型中不同的炎症特征,将像中性粒细胞与淋巴细胞比率 (NLR) 这样的免疫标记物与纤维化严重程度联系起来. 一个新的纤维化-炎症风险模型得分显示了识别晚期纤维化的前景.

科学领域:

肝病学肝病学是一种肝病学.
免疫学免疫学免疫学
内部医学内部医学

背景情况:

肝纤维化是脂肪性肝病 (SLD) 的关键预后因素,包括与代谢功能障碍相关的脂肪性肝病 (MASLD),代谢和酒精相关的肝病 (MetALD) 和与酒精相关的肝病 (ALD).
了解这些SLD表型中独特的炎症概况及其与纤维化的关系,对于准确的预后和管理至关重要.

研究的目的:

为了在MASLD,MetALD和ALD表型中比较系统性炎症和纤维化严重程度.
调查炎症标志物与纤维化存在之间的相关性.
评估免疫炎症标志物与肝纤维化严重程度之间的关联.

主要方法:

180名患有SLD的患者被分为MASLD (n=69),MetALD (n=43) 和ALD (n=68) 组.
过渡性弹性图评估了晚期纤维化 (≥12 kPa) 的肝硬度.
系统性免疫炎症标志物,包括中性粒细胞与淋巴细胞比率 (NLR) 和纤维化得分 (FIB-4,APRI,敏捷3+MELD,CTP) 通过相关性和回归进行了分析.

主要成果:

与酒精相关的肝病 (ALD) 患者表现出最高的中性友负担 (平均NLR6.56),而MASLD患者显示出淋巴细胞占主导的特征 (平均LMR4.86).
149名患者患有高级纤维化,ALD的负担最高 (平均肝硬度为27.43kPa),类似于MetALD和MASLD.
由炎症标志物获得的综合评分准确地识别了晚期纤维化患者.

结论:

尽管临床特征重叠,但MASLD,MetALD和ALD具有独特的炎症特征.
系统性免疫炎症标志物,特别是NLR,与肝纤维化严重程度有显著的关联.
开发的纤维化-炎症风险模型评分为识别晚期纤维化提供了一个潜在的可扩展和具有成本效益的工具,等待进一步验证.

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

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...

Chronic Pancreatitis I: Introduction

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
