Abstract:
Objective:To investigate the clinical value of the expression levels of biological protein markers regenerating islet-derived protein 3-alpha(REG3α), soluble tumor suppressor factor 2(sST2) and tumor necrosis factor receptor 1(TNFR1) in peripheral blood in the diagnosis and efficacy evaluation of intestinal acute graft-versus-host disease (aGVHD) in children after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:Retrospective analysis of 50 children who underwent allo-HSCT, in the Department of Pediatrics, the First Affiliated Hospital of Zhengzhou University from January 2020 to February 2021 were enrolled, including 39 males and 11 females [median age: 8.5 (1-13) years]. The expression levels of above 3 biological proteins were detected before transplantation, 1 week, 2 weeks, 3 weeks, 5 weeks, 7 weeks, 9 weeks, 11 weeks and 13 weeks after transplantation, when intestinal aGVHD occured, and after treatment.Children with intestinal aGVHD were taken as the observation group, and children without intestinal aGVHD were taken as the control group.Whether differences in the expression levels of the 3 biological proteins in the peripheral blood of the 2 groups of children were statistically significant was analyzed.The receiver operating characteristic(ROC) curve was used to evaluate the diagnostic value of the above three biological proteins for intestinal aGVHD, and independent sample t test was performed to compare the expression levels of the 3 biological proteins before and after treatment in children with intestinal aGVHD. Results:(1) The concentrations of REG3α, sST2, and TNFR1 in the peripheral blood of the observation group were (33 985.42±24 631.33) ng/L, (139 899.66±115 825.65) ng/L, (3 041.65±2 418.72) ng/L, respectively, which were higher than the control group of (7 457.39±4 547.49) ng/L, (32 059.57±23 452.85) ng/L, (1 944.51±1 170.35) ng/L, the difference was statistically significant ( t=6.04, 5.19, 2.17, all P<0.05). (2) The area under ROC curve (AUC) of REG3α combined with sST2 in the diagnosis of intestinal aGVHD was 0.952 (95% CI: 0.851-0.992, P<0.001), the maximum Youden index was 0.894, the corresponding sensitivity was 83%, and the specificity was 99%.Its diagnostic value was better than REG3α, sST2 and TNFR1 ( Z=1.763, 1.332, 3.001, all P<0.05). (3) The concentrations of REG3α, sST2, and TNFR1 before treatment in the peripheral blood of children having received effective treatment were (31 343.01±25 364.71) ng/L, (146 629.52±110 501.04) ng/L and (2 489.00±859.70) ng/L, respectively, which were (12 104.37±11 704.60) ng/L, (93 539.55±81 920.93) ng/L and (2 048.15±813.47) ng/L after treatment, lower than those before treatment.The expression levels of REG3α and sST2 were significantly reduced ( t=-3.23, -2.10, all P<0.05), while the difference of the expression level of TNFR1 before and after treatment was not statistically significant ( P>0.05). Conclusions:REG3α and sST2 can be used as important reference indicators for clinical auxiliary diagnosis of intestinal aGVHD, and have good auxiliary diagnostic value.REG3α and sST2 can be used as objective indicators to evaluate the efficacy of clinical treatment of intestinal aGVHD.
