[Anti-cardiolipin antibodies in lupus erythematosus]
Insights
Anti-cardiolipin antibodies (ACA) were found in 43% of lupus erythematosus patients. ACA presence correlated with more severe disease indicators like multiple ARA criteria and malar rash, though not the full ACA syndrome.
Area of Science:
- Immunology
- Rheumatology
- Clinical Medicine
Background:
- Lupus erythematosus is an autoimmune disease with diverse clinical manifestations.
- Anti-cardiolipin antibodies (ACA) are associated with autoimmune conditions and thrombotic events.
Purpose of the Study:
- To investigate the prevalence of ACA in patients with lupus erythematosus.
- To explore the association between ACA and clinical features of lupus erythematosus.
Main Methods:
- Enzyme-linked immunosorbent assay (ELISA) was used to detect ACA in patient serum.
- Serum samples from 79 patients diagnosed with lupus erythematosus were analyzed.
Main Results:
- ACA were detected in 34 out of 79 patients (43%).
- Patients with ACA were more likely to meet 4 or more American Rheumatism Association (ARA) criteria (63.6%) and have malar rash (75%).
- Three patients with thrombocytopenia tested positive for ACA, but no patients met the full criteria for "anti-cardiolipin antibodies syndrome".
Conclusions:
- ACA are prevalent in lupus erythematosus patients and correlate with specific clinical manifestations.
- While ACA are associated with certain lupus features, the complete anti-cardiolipin antibodies syndrome was not observed in this cohort.
- Further research may clarify the role of ACA in lupus pathogenesis and clinical outcomes.
Abstract:
Anti-cardiolipin antibodies (ACA) were investigated in the serum of 79 patients with lupus erythematosus by means of ELISA method. 34 patients (43%) had ACA in their serum. 63.6% of the patients with ACA had 4 or more ARA criteria and 75% of them had malar rash. None of our patients had the "anti-cardiolipin antibodies syndrome" but three of them with thrombocytopenia had ACA.
