Text

Introduction: Physical impairment and inflammatory degenerative processes are hallmarks of auto-inflammatory diseases such as rheumatoid arthritis (RA), psoriasis (PsO) and psoriatic arthritis (PsA) [1]. During inflammation, an accelerated extracellular matrix (ECM) tissue remodeling occurs, leading to unique protease-mediated degradation products of proinflammatory molecules and collagens being released into circulation and quantifiable in serum. We investigated whether ECM biomarker levels were different among rheumatic diseases compared to healthy controls, and whether they were associated with measurements of hand function.

Methods: This is a secondary analysis of serum samples from participants of two hand function studies [1] with identical study procedures for sample collection and assessments. Serum samples were obtained from patients with RA (n=85), PsO (n=96) and PsA (n=107) patients, and from healthy controls (n=50) in the outpatient clinic of the Internal Medicine 3 (Rheumatology and Immunology), Universitätsklinikum Erlangen. Biomarkers of aggrecan (ARG), type I, III and IV collagen (C1M, C3M and C4M) degradation, and a biomarker of macrophage activity (citrullinated and MMP-degraded vimentin; VICM) were measured using immunoassays from Nordic Bioscience A/S. The Moberg-Picking-Up Test (MPUT) [2] and the Michigan Hand Questionnaire (MHQ) [3] were used to evaluate hand function. Differences between biomarker levels among the groups were compared by Kruskal Wallis tests and associations between the biomarkers and hand function parameters in patients with RA, PsO and PsA by Spearman correlations.

Results: ARG and VICM presented higher levels in patients with RA, PsO and PsA compared to healthy controls (Figure 1 A [Fig. 1] and E [Fig. 1], p<0.05). C1M, C3M and C4M were elevated in patients with PsO and PsA compared to RA (Figure 1 B [Fig. 1], C[Fig. 1] and D [Fig. 1], p<0.05). C1M also presented higher levels in patients with PsO compared to PsA, and together with C3M they showed greater levels than in healthy controls (Figure 1 B [Fig. 1] and C [Fig. 1], p<0.05). Among these biomarkers, C1M and VICM were significantly associated with MPUT (ρ=-0.2, ρ=0.1, respectively, both p<0.01), and only C1M with the MHQ (ρ=0.2, p<0.01).

Conclusion: ECM remodeling biomarkers were altered in patients with rheumatic diseases compared to healthy controls, reflecting inflammation-driven tissue damage, and were associated with hand function impairment.
