Cím:	The Leiden mutation of coagulation factor V in Hungarian SLE patients / Nóra Regéczy, Gabriella Lakos, István Balogh, Éva Ajzner, Emese Kiss, Gyula Szegedi

Megjegyzések:	We studied the prevalence and the effect of coagulation factor V Leiden mutation on the occurrence of thrombotic episodes in 120 Hungarian patients having systemic lupus erythematosus (SLE) with or without antiphospholipid antibody. The frequency of the factor V Leiden mutation in Hungarian SLE patients was 13%, which is comparable with those found previously in a healthy Caucasian population. The incidence of venous thrombosis among factor V Leiden carriers has been found to be higher (odds ratio [OR] 1.7) than it is in patients without Leiden mutation (38% vs 29%). In addition, the frequency of venous thrombosis in the heterozygous SLE patients (OR 8.4 [confidence interval (CI) 0.8-83.9] P = 0.06) is dependent on the coexistence of other risk factors, such as antiphospholipid antibody. Moreover, among heterozygous factor V SLE patients, the Leiden mutation could explain the tendency to have significantly higher prevalence of fetal losses (OR 3.9 [CI 1.2-12.0] P = 0.02) and higher prevalence of cerebrovascular lesions, cardiac valvular abnormalities, and Raynaud's syndrome than that found in individuals without factor V Leiden mutation of those having antiphospholipid antibody. Systemic lupus erythematosus patients with combined defects suffer more severely from thrombosis than those with a single risk factor do, suggesting that thrombophilia is a multifactorial disorder in SLE, also. Although, the factor V Leiden mutation does not seem to be a significant risk factor for venous thrombosis in SLE, these data demonstrate that Leiden mutation can be regarded as an additive thrombogenic factor providing higher predisposition to several vasoocclusive disorders in SLE.

Cím:	Hypercoagulability in various autoimmune diseases : no association with factor V Leiden mutation / N. Regéczy, I. Balogh, G. Lakos, M. Zeher, E. Bodolay, G. Szücs, E. Kiss, E. Ajzner, Gy. Szegedi
Dátum:	2000
Megjegyzések:	The coagulation factor V Leiden mutation, leading to resistance to activated protein C (APC), is the most common inherited risk factor for venous thrombosis. In various systemic autoimmune diseases the hypercoagulable state was shown to be associated with the presence of antiphospholipid antibodies (aPL). Our aim was to determine the prevalence of both, Leiden mutation and aPL in autoimmune diseases and their impact on the occurrence of venous thrombosis. The dataset consists of results from 137 patients having Sjögren's syndrome (n = 50), progressive systemic sclerosis (n = 43) (PSS), undifferentiated connective tissue disease (n = 24) (UCTD) and mixed connective tissue disease (n = 20) (MCTD) with or without venous thromboembolic complications. The Leiden mutation was detected with polymerase chain reaction (PCR), aPL, such as lupus anticoagulant (LA) with screening and confirmatory procedures and others with enzyme linked immunosorbent assay (ELISA). The prevalence of mutation ranged between 8.3% and 18.0% (13.1%). The thromboembolic risk was found to be increased in the presence of aPL. Eight patients (5.84%) (4 heterozygous) experienced thromboembolic events and 3 out of 4 heterozygous showed aPL positivity, too. There were no difference between the frequencies of Leiden mutation in examined systemic autoimmune diseases and unselected populations.
