肝组织学检查在慢性乙型肝炎患者病情评估中的价值

目的 进一步研究肝组织学检查在慢性乙型肝炎(CHB)患者病情评估中的价值.方法 对176例入院诊断为CHB的患者进行肝组织活检,同时进行实验室及影像学检查,对临床及病理诊断进行对比分析,以组织学炎症活动度＜G2和≥G2、纤维化程度＜S2和≥S2分组,分别比较肝功能生物化学指标.单因素分析采用秩和检验和x2检验,多因素分析采用双变量Logistic回归分析方法.结果 176例患者临床诊断CHB 171例、肝硬化5例.171例CHB患者中,病理与临床诊断总体符合102例,占59.6%,临床诊断重于病理诊断60例,占35.1%,临床诊断轻于病理诊断9例,占5.3%.44例G2患者中,ALT≥2×正常值上限(ULN)的为41例,占93.2%.多因素Logistic回归分析显示,年龄、明显的症状、ALT、胆碱酯酶(CHE)、Alb、总胆汁酸(TBA)水平及肝脏彩色超声提示肝表面不光滑是肝纤维化分期≥S2相关的独立影响因素.结论 CHB程度分级的临床与病理诊断符合率不高.G2作为CHB中度、S2作为CHB重度的病理学界定标准似乎更符合临床实际.

Abstract：

Objective To explore the value of liver biopsy in diagnosis of the severity of chronic hepatitis B (CHB).Methods The liver biopsy, laboratory examination and imaging were performed in 176 CHB patients. The clinical and histological diagnoses were compared. Biochemical indexes of liver function were also compared between patients with histological inflammation activity ＜G2 and≥G2 or the patients with fibrosis score ＜S2 and ≥S2. Rank sum test and χ2 test were used in univariate analysis. Binary Logistic regression was used in multivariate analysis. Results Among 176patients, the clinical diagnosis of CHB and cirrhosis were established in 171 patients and five patients,respectively. Among 171 CHB patients, the clinical diagnosis was consistent with histological diagnosis in 102 (59.6%) patients. The clinical diagnosis was more severe than histological diagnosis in 60 (35.1%) patients and the clinical diagnosis was less severe than histological diagnosis in nine (5.3%) patients. Among 44 patients with histological grade G2, 41 (93.2 %) patients had alanine aminotransferase (ALT)≥2 × upper limits of normal (ULN). According multiple Logistic regression analysis, age, overt symptom, ALT level, cholinesterase (CHE), albumin (Alb), total bile acid (TBA) and ultrasonic appearance of non-smooth liver surface were independent risk factors for the diagnosis of fibrosis score ≥S2. Conclusions The CHB diagnosis based on clinical evidences doesn't show acceptable consistency with the diagnosis based on histological evidences. G2 and S2 may be more reliable criteria for diagnosing moderate and severe CHB.
