Abstract
Reducing the risk of infectious complications after hip replacement both in the early and late postoperative period remains an important task. Currently, there is a search for laboratory markers of infection development in the field of surgical intervention with high prognostic significance. Violation of the production of catelecidins LL37 may be a factor contributing to the development of infectious and inflammatory complications. To investigate the concentration of cathelicidin in dynamics in patients with hip replacement and the development of postoperative infectious complications.Object and methods. A total of 49 people were examined, who were divided into three groups: the first group – 19 patients after hip replacement with no peculiarities during the postoperative period, the 2nd group – 15 patients after hip replacement: with the development of infection in the early stages (n = 6), and 9 patients with late deep complications within 1 year. The third group (n = 15) consisted of clinically healthy individuals. The results of a laboratory study of LL37 catelecidins in peripheral blood and drainage fluid were analyzed.Results. As a result of the comparative analysis of the results obtained, certain patterns were revealed. Thus, the level of catelecidin in blood serum and drainage fluid in the group of patients with infectious complications was significantly higher than in the group of patients without complications. Blood loss during surgery may be an additional factor contributing to the disruption of the production of antimicrobial peptides. Discriminant analysis revealed that the determination of the level of cathelicidin on the 10th day after surgery and its content in the drainage fluid suggests the development of a postoperative complication in the form of a paraprosthetic infection.
