Changes in the immunological reactivity in patients with coxarthrosis and the factors that determine them

Background. The participation of immune responses in the pathogenesis of degenerative-dystrophic diseases of the synovial joints determines the feasibility of using more rational approaches to assessing the immune status of patients with this pathology. Despite the ongoing immunological studies in patients with degenerative-dystrophic diseases of the hip joint, there are questions related to the functioning of the immune system as a whole, which require additional research.The aim of the study was to establish the features of the relationship between the indicators of the immune status and to identify the factors that determine the nature and severity of immunological disorders in patients with coxarthrosis.Material and methods. The study is based on the results of immunological parameters in 73 patients (mean age – 45.3 ± 2.56 years) with stage III dysplastic coxarthrosis. The data obtained using cluster analysis made it possible to distribute patients into two groups. The first clinical group included 46 patients, the second one – 27 patients. The control group consisted of 28 clinically healthy individuals. Mathematical processing of the results was carried out using the Statistica 6.0 software package (StatSoft Inc., USA) and the mathematical package Mathcad 2001 Pro (MathSoft Inc., USA).Results. The levels of CD4+ and CD8+ cells and IgA were determined as the classification features that make the greatest contribution to the division of the studied groups. Model experiments have shown that a specific combination of the magnitude of each of the noted factors with a certain degree of probability makes it possible to assess the state of the initial immunological reactivity and verify the nature and severity of immunological disorders.Conclusion. The information obtained is of great importance, since it allows predicting the course of the recovery period after surgery and assessing the risk of developing possible postoperative complications in patients with severe articular pathology.
