The investigators aimed to reveal the relationship between serum markers of pyroptosis, GVHD biomarkers and endothelial damage markers in patients who were planned for allogeneic stem cell transplantation for AML and developed GVHD during follow-up. Secondary outcomes of the study were to demonstrate the role of pyroptosis in the pathophysiology of GVHD and transplantation-associated endothelial injury using serum plasma samples; the efficacy of GVHD biomarkers used to demonstrate organ-specific involvement; and the efficacy of GVHD biomarkers and endothelial injury markers in predicting the development of GVHD, transplantation-associated endothelial injury and non-relapse mortality.
In the study, in patients who were planned to receive allogeneic stem cell transplantation for AML, pre-transplant period (before and after central catheter insertion) and post-transplant period (+1, +7, +14, +28, +60 and +100 days in the post-transplant period) serum pyroptosis markers (Serum Gasdermin-D and NLRP-3 Inflammasome levels), GVHD biomarkers (REG-3 alpha, ST2, ELAFIN, HGF, ILR2-alpha, CXCL 9, CXCL 10, CXCL11, BAFF, TNF-alpha, I IL8, IL6 , IL18 , I IL1-beta , IL12 , IFN-gamma) and endothelial damage markers (serums-ICAM , sE-selectin , sVCAM , ANG2 , CRP , vWF , Factor 8 , LDH , d-dimer , transaminase enzyme levels and before transplantation, The aim of this study was to determine the relationship between basic biomarkers in pyroptosis and biomarkers with high predictive value in GVHD and markers of endothelial damage in patients who develop GVHD during follow-up using nail bed capillaroscopic examination and fibroelastographic evaluation to be performed on the twenty-first and hundredth days after transplantation.The serum samples obtained will be compared with the groups of patients with and without GVHD at the planned 1-year follow-up. Patients diagnosed with AML between 15.11.2023 and 15.11.2024 will be included in the study and a total of 2 years of clinical follow-up is planned. In case of loss of participants during follow-up, the study planned to recruit new patients with AML who were scheduled for transplantation between November 15, 2023 and November 15, 2024.
