Insights
Collagen triple helix repeat containing-1 (CTHRC1) levels are elevated in rheumatoid arthritis (RA) patients. Higher CTHRC1 indicates increased disease activity and radiological damage in RA.
Area of Science:
- Rheumatology
- Immunology
- Biochemistry
Background:
- Rheumatoid arthritis (RA) is a prevalent systemic inflammatory condition.
- Collagen triple helix repeat containing-1 (CTHRC1) is a protein known to modulate collagen deposition.
- Understanding CTHRC1's role in RA pathogenesis is crucial for potential therapeutic strategies.
Purpose of the Study:
- To quantify serum CTHRC1 levels in patients with rheumatoid arthritis.
- To investigate the correlation between CTHRC1 levels and clinical, laboratory, and radiological markers of RA.
- To explore CTHRC1 as a potential biomarker for RA disease severity.
Main Methods:
- Serum CTHRC1 levels were measured using Enzyme-Linked Immunosorbent Assay (ELISA).
- The study included 60 adult RA patients and 60 controls (osteoarthritis, reactive arthritis, healthy).
- Disease activity was assessed via DAS28-CRP, and radiological damage using the Simple Erosion Narrowing Score (SENS).
Main Results:
- RA patients exhibited significantly higher serum CTHRC1 levels compared to all control groups.
- Elevated CTHRC1 levels correlated positively with higher disease activity scores (DAS28-CRP).
- Increased CTHRC1 was significantly associated with greater radiological damage (SENS) in RA patients.
Conclusions:
- Serum CTHRC1 levels are significantly elevated in rheumatoid arthritis patients.
- CTHRC1 levels are directly related to disease severity and radiological joint affection in RA.
- CTHRC1 may serve as a valuable biomarker for assessing RA progression and activity.
Background:
Rheumatoid arthritis (RA) is a common systemic inflammatory disease. Collagen triple helix repeat containing-1 (CTHRC1) is a unique gene product able to reduce collagen deposition. The present study aimed to assess CTHRC1 level in RA patients and to uncover its relation to clinical, laboratory and radiological findings.
Methods:
The study included 60 adult RA patients. In addition, there were 60 control subjects who included patients with osteoarthritis (n = 20) and reactive arthritis (n = 20) and healthy controls (n = 20). Serum CTHRC1 levels were assessed by Enzyme-Linked Immunosorbent Assay (ELISA). Disease activity was calculated using the Disease Activity Score (DAS28-CRP). Radiological damage was evaluated using the Simple Erosion Narrowing Score (SENS).
Results:
There was significantly higher serum CTHRC1 levels in RA patients when compared to OA, ReA and control groups [median (IQR): 4.66 (1.68-11.7) versus 1.88 (1.14-2.94), 1.55 (0.98-3.15) and 1.14 (0.85-1.3) mg/dL, respectively, p < 0.001]. There was significantly higher CTHRC1 levels in patients with higher disease activity [median (IQR): 2.23 (1.4-4.73) versus 6.55 (4.66-12.0) mg/dL, p = 0.004]. Patients with higher SENS had significantly higher CTHRC1 [median (IQR): 1.99 (1.4-4.66) versus 9.75 (4.39-12.63) mg/dL, p < 0.001] and DAS28 [median (IQR): 4.25 (2.9-5.2) versus 5.4 (4.65-5.8), p = 0.01].
Conclusion:
Serum CTHRC1 levels are related to disease severity and radiological affection in RA patients.
