摘要/Abstract

摘要： 目的研究胆道闭锁(Biliary atresia,BA)患儿血浆抗核抗体(Antinuclear antibodies,ANA)及抗中性粒细胞胞浆抗体(Antineutrophil cytoplasmic antibody,ANCA)阳性率及其临床意义。方法收集2017年4月至2020年10月行肝移植手术(LT)BA患儿的临床资料并随访LT术后转归,检测其血浆中的ANA(半定量)和ANCA(定性),并分析与术前实验室检查、严重程度、肝脏病理及术后并发症的相关性。计量资料采用秩和检验,计数资料采用χ²检验,相关性分析采用Spearman分析。结果本研究ANA阳性率为3.3%(3/90),且ANA比值随自体肝生存时间延长而降低(R=-0.326),并与Child-Pugh评分(R=0.230)和儿童终末期肝病模型(R=0.257)呈正相关。肝硬化患儿ANA比值显著升高(0.24 vs 0.20,P=0.016),且随细胆管胆栓程度加重而升高(P=0.040)。此外,术后CMV感染者ANA比值显著升高(0.31 vs 0.22,P=0.034)。ANCA阳性率为10.2%(10/98),阳性患儿术前白蛋白(Alb)和胆碱酯酶(CHE)水平显著低于ANCA阴性患儿(Alb:30.4 vs 34.3 g/L,P=0.018;CHE:2.6 vs 3.9 KU/L,P=0.009)。结论 BA患儿血浆中ANA及ANCA阳性率较低,但与肝脏合成功能、病理特征、术后感染等具有相关性,提示自身抗体对评估BA严重程度及预后具有一定的临床价值。

Abstract: Objective To investigate the prevalence rate and clinical significance of plasma antinuclear antibody (ANA) and antineutrophil cytoplasmic antibody (ANCA) in patients with biliary atresia (BA). Methods The clinical and follow-up data of BA patients underwent liver transplantation (LT) from April 2017 to October 2020 were retrospectively collected. The plasma ANA were semi-quantitatively measured and ANCA were qualitatively detected, and the correlation with laboratory parameters, severity, pathological histological features and post-LT complications were analyzed. Rank sum test was used for continuous data and Chi-square test was used for categorical data. Correlations were evaluated by the Spearman's correlation analysis. Results The prevalence rate of ANA was 3.3% (3/90), and the ANA ratio decreased with the length of native liver survival (R=-0.326). There was a positive correlation between the ANA ratio and Child-Pugh score (R = 0.230), as well as score of pediatric model of end-stage liver disease (R=0.257). The ANA ratio was significantly higher in patients with cirrhosis (0.24 vs 0.20, P=0.016) and the ratio increased with higher degree of ductular cholestasis (P=0.040). In addition, the ANA ratio was significantly higher in patients with CMV infection post-LT (0.31 vs 0.22, P=0.034). The ANCA positive rate was 10.2% (10/98). Prior-LT, plasma Albumin (Alb) and cholinesterase (CHE) level in ANCA-positive patients was significantly lower than that in ANCA-negative patients (Alb: 30.4 vs 34.3 g/L, P=0.018; CHE: 2.6 vs 3.9 KU/L, P=0.009). Conclusion The prevalence rate of ANCA and ANA of patients with BA is low, but it correlates with liver synthetic function, fibrosis stage and post-LT CMV infection. Autoantibodies may be of clinical value for the assessment of BA severity and post-LT prognosis.
