image of Expression of CD68+ Cells in Synovial Tissue from Patients with PsA and its Association with Disease Activity Indices: A Clinical Pilot Study

Abstract

Introduction

Investigating CD68+ positive cells in the synovial tissue is crucial for understanding the pathogenesis of psoriatic arthritis (PsA) and developing targeted treatment strategies. The role of CD68+ positive cells in the synovial tissue of patients with PsA for joint destruction has not been fully studied.

Objective

The objective of the study was to examine the presence of CD68+ cells in the synovial tissue of patients with PsA, particularly those with high inflammatory activity.

Methods

Synovial tissue samples were collected during knee joint replacement surgeries from patients with PsA (16 patients) and gonarthrosis (25 patients). Immunohistochemical methods were employed to detect CD68+ cell expression in the tissue samples. The results were analyzed by histologists, and the staining intensity and percentage of positively stained cells were evaluated. The data were then divided into three groups for statistical analysis: negative, weakly positive, and strongly positive histological samples. Routine indices for disease activity, VAS, DAPSA, PASDAI, and mCPDAI were used to assess PsA activity in all patients and to assess correlations with CD68+ positive cells in the synovial tissue. Statistical analysis was performed using SPSS version 26.0 (SPSS Inc., Chicago, IL, USA).

Results

The expression of CD68+ positive cells was significantly higher in patients with PsA compared to those with activated gonarthrosis ( < 0.001). The indices for disease activity, VAS, DAPSA, PASDAI, mCPDAI, and mCPDAI showed a significant positive relationship with the expression of CD68 + cells on synovial tissue in patients with PsA ( < 0.01)

Conclusion

The findings of the study confirm the increased numbers of CD68+ cells in PsA vs. gonathrosis synovium. This suggests the need to explore therapeutic approaches aimed at suppressing or blocking CD68+ cells to potentially mitigate joint damage.
