Programmed cell death protein-1 (PDCD1) is considered a key factor in immune regulation and is expressed mainly on activated T cells. The current study aimed to assess the clinical value of soluble PDCD1/PD1 as a marker for diagnosing type-1 autoimmune hepatitis in children. Sixty children with chronic hepatitis as patients' groups further divided into autoimmune hepatitis group and other chronic liver disease group and 20 healthy children as a control group were enrolled in this study. All children have been studied for clinical profile, biochemical, histological features and serum level of soluble programmed cell death protein-1 by ELISA. There was a significant increase regarding soluble PDCD1/PD1 in the autoimmune hepatitis group than the chronic liver disease group, with the lowest level in the control group. Soluble PDCD1/PD1 level increased with higher fibrosis stage and higher Child Pugh score, also higher in relapsed patients than patients with complete remission in AIH groups. There was a positive correlation between soluble PDCD1/PD1 and PT, IgG, fibrosis stage, HAI, ALT, AST, simplified and revised score system, PELD and MELD among the AIH group. The best cutoff value of PDCD1/PD1 in the prediction of autoimmune hepatitis was 1.73 ng/ml with AUC:0.895 that has a sensitivity of 80%, specificity of 78%. sPDCD1/PD1 level represents a possible promising biomarker of AIH patients who will represent an incomplete response for regular treatment. This finding can be considered as the first step to prove the pivotal role of soluble PDCD1/PD1 in the diagnosis of AIH.

可溶性程序性细胞死亡蛋白-1在埃及儿童1型自身免疫性肝炎中的诊断价值。

程序性细胞死亡蛋白-1(PDCD1)被认为是免疫调节的关键因素,主要在活化的T细胞上表达。当前的研究旨在评估可溶性PDCD1 / PD1作为诊断儿童1型自身免疫性肝炎的标志物的临床价值。这项研究将60例慢性肝炎患儿作为患者组,进一步分为自身免疫性肝炎组和其他慢性肝病组,并将20例健康儿童作为对照组。通过ELISA研究了所有儿童的临床特征,生化,组织学特征和可溶性程序性细胞死亡蛋白-1的血清水平。与慢性肝病组相比,自身免疫性肝炎组中可溶性PDCD1 / PD1的含量显着增加,而对照组中的水平最低。随着AIH组纤维化分期的升高和Child Pugh评分的升高,可溶性PDCD1 / PD1水平也升高,复发患者的可溶性PDCD1 / PD1水平也高于完全缓解的患者。AIH组中可溶性PDCD1 / PD1与PT,IgG,纤维化分期,HAI,ALT,AST,简化和修订评分系统,PELD和MELD呈正相关。在预测自身免疫性肝炎时,PDCD1 / PD1的最佳临界值为1.73 ng / ml,AUC:0.895,灵敏度为80%,特异性为78%。sPDCD1 / PD1水平代表AIH患者可能的有前途的生物标志物,对于常规治疗而言,这将代表不完全的反应。这一发现可以被认为是证明可溶性PDCD1 / PD1在AIH诊断中的关键作用的第一步。在AIH组中,复发患者也比完全缓解的患者高。AIH组中可溶性PDCD1 / PD1与PT,IgG,纤维化分期,HAI,ALT,AST,简化和修订评分系统,PELD和MELD呈正相关。在预测自身免疫性肝炎时,PDCD1 / PD1的最佳临界值为1.73 ng / ml,AUC:0.895,灵敏度为80%,特异性为78%。sPDCD1 / PD1水平代表AIH患者可能的有前途的生物标志物,对于常规治疗而言,这将代表不完全的反应。这一发现可以被认为是证明可溶性PDCD1 / PD1在AIH诊断中的关键作用的第一步。在AIH组中,复发患者也比完全缓解的患者高。AIH组中可溶性PDCD1 / PD1与PT,IgG,纤维化分期,HAI,ALT,AST,简化和修订评分系统,PELD和MELD呈正相关。在预测自身免疫性肝炎时,PDCD1 / PD1的最佳临界值为1.73 ng / ml,AUC:0.895,灵敏度为80%,特异性为78%。sPDCD1 / PD1水平代表AIH患者可能的有希望的生物标志物,对于常规治疗而言,这将代表不完全的反应。这一发现可以被认为是证明可溶性PDCD1 / PD1在AIH诊断中的关键作用的第一步。简化和修订的评分系统,AIH组中的PELD和MELD。在预测自身免疫性肝炎时,PDCD1 / PD1的最佳临界值为1.73 ng / ml,AUC:0.895,灵敏度为80%,特异性为78%。sPDCD1 / PD1水平代表AIH患者可能的有希望的生物标志物,对于常规治疗而言,这将代表不完全的反应。这一发现可以被认为是证明可溶性PDCD1 / PD1在AIH诊断中的关键作用的第一步。简化和修订的评分系统,AIH组中的PELD和MELD。在预测自身免疫性肝炎时,PDCD1 / PD1的最佳临界值为1.73 ng / ml,AUC:0.895,灵敏度为80%,特异性为78%。sPDCD1 / PD1水平代表AIH患者可能的有前途的生物标志物,对于常规治疗而言,这将代表不完全的反应。这一发现可以被认为是证明可溶性PDCD1 / PD1在AIH诊断中的关键作用的第一步。
