Insights
Hyperhomocysteinemia (high Hcy) is prevalent in Systemic Lupus Erythematosus (SLE) patients, particularly those with antiphospholipid syndrome. Elevated Hcy levels correlate with antiphospholipid antibodies, suggesting a link to thrombotic events.
Area of Science:
- Rheumatology
- Clinical Chemistry
- Immunology
Context:
- Systemic Lupus Erythematosus (SLE) is an autoimmune disease with increased thrombotic risk.
- Antiphospholipid syndrome (APS) is a major contributor to morbidity and mortality in SLE patients.
- Hyperhomocysteinemia (Hcy > 9) is a potential risk factor for thrombosis.
Purpose:
- To determine the prevalence of hyperhomocysteinemia in SLE patients with and without antiphospholipid syndrome.
- To compare Hcy levels between SLE patients and healthy controls.
- To investigate the correlation between hyperhomocysteinemia and antiphospholipid antibodies in SLE.
Summary:
- This study included 44 SLE patients (17 with APS, 27 without) and 24 healthy controls.
- Prevalence of hyperhomocysteinemia was 61.4% in SLE patients.
- Elevated Hcy levels were significantly higher in SLE patients compared to controls (p=0.002), and in SLE patients with APS (p=0.003) and without APS (p=0.015) versus controls.
- A significant association was found between hyperhomocysteinemia and anticardiolipin antibodies (aCL(+)) in SLE patients (75% of aCL(+) patients had hyperhomocysteinemia).
Impact:
- Findings highlight hyperhomocysteinemia as a common metabolic abnormality in SLE.
- The correlation between Hcy and antiphospholipid antibodies suggests a shared pathway in thrombosis pathogenesis.
- This research may inform targeted interventions for managing thrombotic risk in SLE patients.
Objectives:
to detect the prevalence of hyperhcy in SLE patients with and without antiphospholipid syndrom; to compare the Hcy levels between those patients and healthy controls and to determine the correlation between hyperhcy and antiphospholipid antibodies.
Patients And Methods:
we studied 44 SLE patients: 17 had antiphospholipid syndrom and 27 didn't have it, and we compared them to 24 healthy controls. All of them where checked clinically and with laboratory tests like anticardiolypin antibodies, lupus anticoagulant and Hcy. Hcy > 9 was considered abnormal. Patient who had hyperhcy were treated with folic acid+vitB6+vitB12 a month along.
Statistical Analysis:
cualytative variables: chi square or Fischer's; cuantitative variables: Student's T test or Mann-Whitney's test.
Results And Conclusions:
there were 35 trombotic manifestations in 44 patients. Hyperhcy was present in 27 SLE patients (61,4%), 12 of them had antiphospholipid syndrom. Hcy concentrations patients vs.controls was statisticaly different (p=0,002). There was also stastisticaly different the hcy concentration from SLE patients with SAF vs controls (p=0,003) and without SAF vs controls (p= 0,015). From 33 SLE patients, 20 (33%) were aCL(+). 15(75%) of them had hiperhcy.
