ABSTRACT
OBJECTIVE: To investigate the association of serum MMP-2, Siglec-1, and Th1/Th2 cell ratio with disease activity in rheumatoid arthritis (RA).
METHODS: Between August and November 2020, Peking University People’s Hospital recruited 40 patients with RA and 40 healthy individuals. Various methods such as ELISA, flow cytometry, and RT-PCR were used to assess the levels of sCR1, MMP-2, MMP-9, and Siglec-1 in the participants. Correlation analysis was conducted between Siglec-1 expression and DAS28 and hs-CRP. T lymphocyte subsets; cytokines IFN-γ and IL-4, were assessed using flow cytometry and ELISA in both patient groups.
RESULTS: Rheumatoid arthritis was linked to lower levels of serum sCR1 and higher levels of MMP-2 and MMP-9 compared to healthy individuals (P < .05). The percentage of Siglec-1-positive cells in PBMCs was significantly higher in patients with RA than in the healthy group (P < .05), with monocytes being the predominant cells expressing Siglec-1. Patients with RA exhibited a significantly higher expression of Siglec-1 mRNA compared to those in a healthy condition (P < .05), and the expression of Siglec-1 in these patients was positively correlated with DAS28 and hs-CRP (P < .05). Study patients demonstrated a notably lower level of peripheral blood CD8+ cells and a higher CD4+/CD8+ ratio when compared to healthy individuals (P < .05). There was no statistically significant difference in CD3+CD4+ levels between the 2 groups (P > .05). Rheumatoid arthritis was associated with a higher level of peripheral blood IFN-γ and a lower IL-4 level than healthy individuals (P < .05).
CONCLUSION: There was a strong link between sCRl, MMP-2, and MMP-9 and the progression of rheumatoid arthritis. These markers can effectively monitor disease activity in patients with rheumatoid arthritis. Siglec-1 is highly expressed in peripheral blood and can be used to track disease activity and inflammation in these patients. Regulating Th1/Th2-mediated homeostasis may help alleviate symptoms in individuals with rheumatoid arthritis.
