The detection of predictors probabilistic characteristics of acute renal graft rejection on the part of a recipient

Abstract

Acute renal graft rejection (ARGR) may be the cause of its dysfunction and loss in the postoperative period. Objectives. To identify possible predictors of ARGR based on the analysis of the alleged risk factors on the part of a recipient. Material and methods. A retrospective study of medical cards of 248 patients who underwent cadaveric kidney allotransplantation (CKA) was carried out. The influence of the following factors on the probability of developing ARGR was assessed: weight, age, blood group, Rh factor, gender of a recipient, duration of renal replacement therapy (RRT). Data processing was carried out by CRT analysis for the “decision tree” method (SPSS Statistics 22 program), and also using Pearson’s chi-square test (Statistica software package). Results. The study has revealed that being on RRT for more than 9.5 months statistically significantly increases the likelihood of developing ARGR in the postoperative period, especially in the group of patients with IV (AB) blood type. Conclusions. Factors such as the duration of RRT for more than 9.5 months and the IV(AB) blood group a type of a recipient, both individually and in combination, can be considered as predictors of ARGR development. Therefore, measures to reduce the incidence of ARGR should be aimed at reducing the duration of RRT, as well as restrictions of recipients with IV(AB) blood group type on being under RRT for more than 9.5 months.
