Serum levels of CA 125 are elevated in patients with active systemic lupus erythematosus
Insights
Systemic lupus erythematosus (SLE) patients with active disease show higher CA 125 serum levels compared to those in remission. Elevated CA 125 may indicate disease activity in lupus patients.
Area of Science:
- Immunology
- Rheumatology
- Clinical Chemistry
Background:
- Systemic lupus erythematosus (SLE) is a chronic autoimmune disease.
- CA 125 is a tumor-associated antigen, but its role in non-malignant conditions like SLE is under investigation.
- Disease activity in SLE can affect various organ systems and inflammatory markers.
Purpose of the Study:
- To investigate the correlation between serum CA 125 levels and disease activity in patients with systemic lupus erythematosus.
- To determine if CA 125 can serve as a potential biomarker for SLE activity.
Main Methods:
- Serum CA 125 levels were measured in 37 female patients diagnosed with SLE.
- Patients were categorized into two groups: inactive disease (N=9) and active disease (N=28).
- Statistical analysis was performed to compare CA 125 levels between the groups.
Main Results:
- CA 125 levels were significantly higher in patients with active SLE compared to those in remission.
- The median CA 125 level in the remission group was 9 U/mL (range 4-132).
- The median CA 125 level in the active disease group was 18 U/mL (range 2-272), with 10 out of 28 patients exceeding the 35 U/mL upper limit.
Conclusions:
- Elevated serum CA 125 levels are associated with active disease in patients with systemic lupus erythematosus.
- CA 125 may represent a useful biomarker for monitoring disease activity in SLE.
- Further research is warranted to elucidate the precise role of CA 125 in SLE pathogenesis.
Abstract:
Levels of CA 125 were measured in the serum of 37 female patients with systemic lupus erythematosus. The patients were classified into two groups according to the absence or presence of signs of disease activity: inactive (N = 9) and active disease (N = 28). CA 125 levels were higher in the group of patients with active disease. In the remission group the median was 9 U/mL (range 4-132), whereas in the group of patients with active disease, the median was 18 U/mL (range 2-272). Among patients with active disease, values higher than the generally accepted upper limit of 35 U/mL were found in ten of 28 cases.
