The clinical significance of portal hypertensive gastropathy (PHG) in patients with compensated liver disease is not well established. The aim of this study was to determine the prevalence and correlates of PHG in a large cohort of patients with chronic hepatitis C virus (HCV) infection and bridging fibrosis/compensated cirrhosis entering the randomized phase of the Hepatitis C Antiviral Long-term Treatment against Cirrhosis trial (HALT-C).
The presence and severity of PHG in 1,016 HCV patients with no prior history of gastrointestinal bleeding was determined at surveillance endoscopy using the New Italian Endoscopy Club criteria.
Overall, 37% of HALT-C patients had PHG with 34% having mild and 3% with severe changes. The mucosal mosaic pattern was identified in 33%, red marks in 15%, and gastric antral vascular ectasia (GAVE) features in only 3%. Independent correlates of PHG included biochemical markers of liver disease severity (lower serum albumin, higher bilirubin), portal hypertension (lower platelet count), insulin resistance (higher glucose), and non-African American race. Independent correlates of GAVE included a history of smoking, nonsteroidal anti-inflammatory drugs (NSAIDs) use within the past year, and higher serum bilirubin and glucose levels. There was a strong positive association between the presence of PHG and esophageal varices (p < 0.0001).
PHG is associated with the histological and biochemical severity of liver disease in patients with HCV and advanced fibrosis but is mild in most patients. The clinical relevance of these findings will be further explored during the randomized phase of the HALT-C study.
代偿期肝病患者门静脉高压性胃病(PHG)的临床意义尚未明确。本研究旨在确定大量慢性丙型肝炎病毒(HCV)感染且有桥接纤维化/代偿期肝硬化的患者进入丙型肝炎抗病毒长期治疗抗肝硬化试验(HALT-C)随机阶段时PHG的患病率及其相关因素。
采用新意大利内镜俱乐部标准,在监测性内镜检查中确定1016例无胃肠道出血既往史的HCV患者中PHG的存在及严重程度。
总体而言,HALT-C研究中的患者有37%发生PHG,其中34%为轻度改变,3%为重度改变。33%的患者可见黏膜马赛克样改变,15%有红色征,仅有3%有胃窦血管扩张(GAVE)特征。PHG的独立相关因素包括肝病严重程度的生化指标(血清白蛋白降低、胆红素升高)、门静脉高压(血小板计数降低)、胰岛素抵抗(血糖升高)以及非非裔美国人种族。GAVE的独立相关因素包括吸烟史、过去一年内使用非甾体抗炎药(NSAIDs)以及血清胆红素和血糖水平升高。PHG的存在与食管静脉曲张之间存在强正相关(p < 0.0001)。
PHG与HCV及晚期纤维化患者的肝病组织学和生化严重程度相关,但大多数患者病情较轻。这些发现的临床相关性将在HALT-C研究的随机阶段进一步探讨。
