Hyperhomocysteinemia - an additional risk factor of thrombosis in systemic lupus erythematosus and antiphospholipid syndrome
Objective. To assess homocystein (HC) level in systemic lupus erythematosus (SLE) with antiphospholipid syndrome (APS) and its relation to thrombosis development and blood lipide spectrum disturbances. Material and methods. 32 pts (12 male and 20 female) with mean age 36 12 years and mean disease du...

| Summary: | Objective. To assess homocystein (HC) level in systemic lupus erythematosus (SLE) with antiphospholipid syndrome (APS) and its relation to thrombosis development and blood lipide spectrum disturbances. Material and methods. 32 pts (12 male and 20 female) with mean age 36 12 years and mean disease duration 13 11 years were included. 8 pts had SLE without APS, 13 - SLE with APS and 11 - primary APS (PAPS). All pts were divided into 2 groups depending on blood HC level. 26 pts with HC level more than 12 mcg/d! were included In group 1 and 6 pts with HC level less than 12 mcg/dl - in group 2. HC level was measured with high efficacious liquid chromatography (HELC). Lipid-protein blood spectrum was assessed in all pts. Results. Elevated HC level was revealed in 26 from 32 pts: in 16 with SLE (including 12 pts with APS) and in 10 with PAPS. HC concentration did not depend on APS presence, but frequence of hyperhomocysteinemia (HHC) significantly associated with APS and thrombotic complications. 20 from 26 (76,9%) pts with HHC had thrombosis history. Only I from 6 (16,7%) pts with normal HC level had thrombosis history (exact Fisher test p=0,02). HC level did not depend on age and sex. Changes of blood lipid-protein indices were revealed in most pts. Lipid spectrum disturbances were confined largely to cholesterol elevation due to increase of atherogenic lipoproteins cholesterol. Only 22% of pts showed decrease of antiatherogenic lipoproteins concentration. Bblood lipid-protein spectrum indices did not depend on HC level. Conclusion. HHC is present in 84,6% of pts with APS (primary and secondary). In pts with APS HHC is more frequent than in pts without APS. HHC is associated with thrombotic complications. HHC and lipid-protein spectrum disturbances are independent risk factors of thrombotic complications in pts with SLE and APS. |
