The characteristics of cellular element of immunity before and after endoprosthesis of large joints

The aim of the research is to study the indices of cellular immunity in patients before and after hip joint endoprosthesis. Materials and methods. The indices of cellular element of immunity (quantitative and qualitative composition of T-lymphocytes (CD3+), T-helpers (CD3+CD4+), cytotoxic T-lymphocytes (CD3+CD8+), B-lymphocytes (CD3-CD19+), natural killers (CD3-CD16+CD56)) in 20 patients with post-traumatic osteoarthrosis of III grade preoperatively and in the dynamic follow-up on the 3rd, 7th and 21st day post-surgically. Results. Patients with osteoarthrosis showed expressed immunological impairments both before and after endoprosthesis mostly affecting T-cellular immunity element and manifesting in immunoregulatory subpopulations imbalance as well as in T-suppressors decrement, T-helpers increment and NK-cells enlargement in patients after endoprosthesis. Conclusion. Patients with osteoarthrosis showed expressed immunological impairments both before and after joint endoprosthesis. Surgical intervention resulted in the aggravation of the pre-surgical disturbances in immunodeficiency.
