摘要:
目的 比较自身抗体阳性和阴性的自身免疫性肝炎(AIH)患者的临床与病理特征,总结诊断经验。 方法 回顾性入组2010年1月—2021年8月就诊于北京地坛医院经肝脏组织病理学诊断为AIH的患者为研究对象,根据有无自身抗体分为自身抗体阳性组和自身抗体阴性组,对比两组患者的生化、免疫、组织病理、疾病分期及临床症状体征等特征。计量资料组间比较采用t检验或Mann-Whitney U检验;计数资料组间比较采用χ2检验或Fisher确切概率法。 结果 共入组110例患者,自身抗体阳性患者78例(71%),自身抗体阴性患者32例(29%),检测的主要抗体为抗核抗体(ANA)、抗线粒体抗体(AMA)、抗平滑肌抗体(ASMA),其中ANA阳性74例(67.27%),AMA阳性1例(0.91%),ASMA阳性5例(4.55%),抗Ro-52抗体阳性14例(12.73%)。临床、免疫方面,自身抗体阴性组皮肤巩膜黄染(21.90% vs 50.00%,χ2=7.377, P=0.007)、纳差(18.80% vs 41.00 %,χ2=4.979,P=0.026)发生率、DBil[7.30(4.05~12.10)μmol/L vs 16.80(6.48~69.75)μmol/L,Z=-2.304,P=0.021]、IgG[16.40(13.15~18.05)g/L vs 20.30 (16.00~27.15)g/L, Z=-2.715,P=0.007]、Glo[30.60(26.00~34.90)g/L vs 37.30(30.50~42.50)g/L,Z=-3.356,P=0.001]中位数水平均低于自身抗体阳性组。肝组织病理方面,自身抗体阳性患者淋巴细胞浸润(91.03% vs 68.75%,χ2=6.997,P=0.008)及浆细胞浸润(82.05% vs 50.00 %,χ2=11.572,P=0.001)的比例显著高于自身抗体阴性患者;ANA阳性患者平均炎症水平(G1~G4)及纤维化水平(S1~S4)均显著高于ANA阴性患者(9.46% vs 5.56%,16.22% vs 27.78%,44.59% vs 63.89%,29.73% vs 2.78%;Z=-2.179, P=0.029);(37.84% vs 13.89%,25.68% vs 41.67%,32.43% vs 30.56%,4.05% vs 13.89%;Z=-0.082, P=0.037)。 结论 与自身抗体阳性AIH患者相比,自身抗体阴性的AIH患者病情多处于疾病初期,IgG不高,临床易漏诊,早期的、积极的肝穿刺病理活检尤为重要。 Abstract:Objective To compare clinical and pathological features between autoimmune hepatitis (AIH) patients with positive and negative autoantibodies, and to summarize the experience in diagnosis. Methods A retrospective analysis was performed for the patients who attended Beijing Ditan Hospital from January 2010 to August 2021 and were diagnosed with AIH by liver histopathology, and according to the presence or absence of autoantibodies, they were divided into positive autoantibody group and negative autoantibody group. The two groups were compared in terms of biochemical parameters, immunological features, histopathological features, disease stage, and clinical symptoms and signs. The t-test or the Mann-Whitney U test was used for comparison of continuous data between groups, and the chi-square test or the Fisher's exact test was used for comparison of categorical data. Results A total of 110 patients were enrolled, among whom 78 (71%) had positive autoantibodies and 32 (29%) had negative autoantibodies. Anti-nuclear antibody (ANA), anti-mitochondrial antibody (AMA), and anti-smooth muscle antibody (ASMA) were the main autoantibodies detected, and of all 110 patients, 74 (67.27%) had positive ANA, 1 (0.91%) had positive AMA, 5 (4.55%) had positive ASMA, and 14 (12.73%) had positive anti-Ro-52 antibody. As for clinical and immunological features, compared with the positive autoantibody group, the negative autoantibody group had significantly lower incidence rates of jaundice of the skin and sclera (21.90% vs 50.00%, χ2=7.377, P=0.007) and poor appetite (18.80% vs 41.00%, χ2=4.979, P=0.026) and significantly lower median levels of direct bilirubin [7.30(4.05~12.10) μmol/L vs 16.80(6.48~69.75) μmol/L, Z=-2.304, P=0.021], IgG [16.40(13.15~18.05) g/L vs 20.30(16.00~27.15) g/L, Z=-2.715, P=0.007], and GLo [30.60(26.00~34.90) g/L vs 37.30(30.50~42.50) g/L, Z=-3.356, P=0.001]. In terms of liver histopathology, compared with the negative autoantibody group, the positive autoantibody group had a significantly higher proportion of patients with lymphocyte infiltration (91.03% vs 68.75%, χ2=6.997, P=0.008) and plasma cell infiltration (82.05% vs 50.00%, χ2=11.572, P=0.001); compared with the ANA-negative patients, the ANA-positive patients had significantly higher inflammation grade (G1-G4) (9.46%/16.22%/44.59%/29.73% vs 5.56%/27.78%/63.89%/2.78%, Z=-2.179, P=0.029) and fibrosis degree (S1-S4) (37.84%/25.68%/32.43%/4.05% vs 13.89%/41.67%/30.56%/13.89%, Z=-0.082, P=0.037). Conclusion Compared with AIH patients with positive autoantibodies, AIH patients with negative autoantibodies are mostly in the early stage of the disease and tend to have a low level of IgG, with a relatively high rate of missed diagnosis in clinical practice. Early and active liver biopsy is of particular importance. -
