AbstractBackground:The objective of the work was to study the manifestations of antiphospholipid syndrome (APS) in the Chinese population, and evaluate the ability of lupus anticoagulant (LAC) assays to identify APS.Methods:Consecutive patients with APS from 2012 to 2015 in our hospital were recruited, strictly following the Sydney revised Sapporo criteria for APS classification. Meanwhile, in the LAC-positive population, LAC normalized ratios obtained from diluted Russell viper venom time (DRVVT) and silica clotting time (SCT) assays were compared between patients with and without APS.Results:One hundred and seventeen patients with defined APS comprised 86 women and 31 men with a mean age of 38 years (range 9–78 years), 38 (32.5%) of them had systemic lupus erythematosus. The prevalence of arterial thrombosis, venous thrombosis and obstetric complications were 46.2%, 25.6% and 30.8%, respectively. LAC was detected in 105 patients (89.7%), anti-βConclusions:A high prevalence of arterial thrombosis and LAC-positive result was noted in Chinese patients with APS, and an appropriate threshold for LAC normalized ratios could help to discriminate APS from non-APS patients in the LAC-positive population.

Objective.Antiphospholipid syndrome (APS) is characterized by thrombosis (venous and arterial) and pregnancy loss in conjunction with the lupus anticoagulant, IgG or IgM anticardiolipin, or IgG or IgM anti-ß2-glycoprotein I. In most series, only a minority of patients with antiphospholipid antibodies develop a clinical manifestation.Methods.A cross-sectional study of consecutive patients in the Hopkins Lupus Center was performed. Interviews were done and records were reviewed for the following variables: gender, ethnicity, hypertension, triglycerides, cholesterol, smoking, diabetes mellitus, homocysteine, cancer, hepatitis C, hormone replacement therapy/oral contraceptives, hereditary thrombophilia, anticardiolipin antibodies IgG, IgM and IgA, and lupus anticoagulant (LAC). Our aim was to identify risk factors associated with thrombosis and pregnancy loss in patients with antiphospholipid antibodies.Results.A total of 122 patients (84% female, 74% Caucasian) were studied. Patients were divided into 3 groups: primary APS, APS associated with systemic lupus erythematosus, and patients with systemic lupus erythematosus (SLE) with antiphospholipid antibodies but no thrombosis or pregnancy loss. Venous thrombosis was associated with high triglycerides (p = 0.001), hereditary thrombophilia (p = 0.02), anticardiolipin antibodies IgG > 40 (p = 0.04), and LAC (p = 0.012). Hypertriglyceridemia was associated with a 6.4-fold increase, hereditary thrombophilia with a 7.3-fold increase, and anticardiolipin IgG > 40 GPL with a 2.8-fold increase in the risk of venous thrombosis. Arterial thrombosis was associated with hypertension (p = 0.008) and elevated homocysteine (p = 0.044). Hypertension was associated with a 2.4-fold increase in the risk of arterial thrombosis. No correlations were found for pregnancy loss.Conclusion.The frequency of thrombosis and pregnancy loss is greater in APS associated with SLE than in primary APS. Risk factors differ for venous and arterial thrombosis in APS. Treatment of hypertension may be the most important intervention to reduce arterial thrombosis. Elevated triglycerides are a major associate of venous thrombosis, but the benefit of treatment is not known. Hereditary thrombophilia is an associate of venous but not arterial thrombosis, making it cost-effective to investigate only in venous thrombosis.

Objective To investigate the association of the CD11b single nucleotide polymorphism (SNP) rs1143679 with systemic lupus erythematosus (SLE) in Han Chinese patients, and to clarify this association with SLE clinical manifestations. Methods PCR–restriction fragment length polymorphism and direct sequencing of CD11b rs1143679 were conducted in 584 patients with SLE and 628 healthy controls in this case–control study to compare genotype and allele frequency distributions. Correlations between CD11b genotypes and clinical manifestations were also determined. Results The frequency of the CD11b rs1143679 GA genotype was 1.89% in Han Chinese patients with SLE, which was much lower than that of European and American populations, but close to the frequency observed in individuals from Hong Kong and Thailand. The CD11b rs1143679 GA genotype was also shown to confer susceptibility to SLE (odds ratio = 4.00, 95% confidence interval = 1.11–14.41). CD11b rs1143679 was found to be significantly associated with nephritis, but not with age of disease onset, arthritis, hematological involvement, or neural lesions. Conclusion CD11b rs1143679 appears to be associated with risk for SLE in the Han Chinese population, and may play an important role in the development of lupus nephritis.

The aim of the study was the assessment of the prevalence of antiphospholipid syndrome (APS) in patients with systemic lupus erythematosus (SLE). 72 patients with SLE had been investigated, 66 females and six males, aged 17 to 70 years, average 37,03. The presence of APA was determined using both ELISA assay for antiphospholipid antibodies ASSERACHROM APA by Diagnostica Stago and clotting tests for lupus anticoagulant: activated partial thromboplastin time (aPTT), tissue thromboplastin inhibition test (TTI) and dilute Russell viper venom time (dRVVT). Antiphospholipid antibodies have been found in 24 patients (33.44%), 10 of them were. with positive lupus anticoagulant tests, 6 of them were with positive ELISA test, while 8 of them had positive coagulation and immunological tests. Clinical manifestations that could be related to antiphospholipid syndrome were present in 22 patients (30.5%). The most common were thrombotic complications in 16 patients (22.25), recurrent spontaneous abortions in 7 patients (9.7%) and thrombocytopenia in 1 patient (1.39%). Presence of antiphospholipid syndrome was determined in 15 patients (20.83%). We can conclude that there is a significant correlation between presence of antiphospholipid antibodies and both thrombotic events and recurrent spontaneous abortions in SLE patients. Occurrence of thrombotic complications is in direct correlation with the level of antiphospholipid antibodies.

SummaryThromboembolic complications are frequently observed in patients with systemic lupus erythematosus (SLE). Significant associations have been reported between these complications and the presence of antiphospholipid antibodies, notably the lupus anticoagulant and anti-cardiolipin antibodies. Factor V Leiden is a genetic disorder associated with an increased risk of venous thrombosis. We studied these factors in 173 patients with SLE in relation to both arterial and venous thrombosis. The frequency of factor V Leiden in SLE patients is comparable to that in the Dutch population (5%) and a risk factor for venous thrombosis (odds ratio 4.9; Cl 1.2-19.6), but not for arterial thrombosis. The lupus anticoagulant is a risk factor for both arterial thrombosis (odds ratio 7.1; Cl 2.9-17.4) and venous thrombosis (odds ratio 6.4; Cl 2.7-15.4). From multivariate analysis, both the lupus anticoagulant and factor V Leiden appeared independent risk factors for venous thrombosis.

Background:Cognitive impairment (CI) in systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS) patients have been poorly described and recognized.Objectives:to describe the rates and spectrum of CI in primary (PAPS) and secondary to systemic lupus erythematosus (SLE) (SAPS) APS patientsMethods:113 patients (70 with APS (37 – PAPS, 33 – SAPS) and 43 - SLE without APS), 89 (78,8%) – women, were consecutively enrolled in the study. The mean (M±SD) age was 37,9±11,9 years. SLE activity was measured by SLEDAI scale. Mental disorders (MD) were diagnosed by psychiatrist in accordance with ICI-10 in semi-structured interview. CI were diagnosed with psychology and neuropsychology methodsResults:CI of varying severity were found in 105 (92,9%) patients: 62,9% - mild, 23,8% - moderate and 13,3% - severe. Severe and moderate CI were more associated with APS (48,6% in PAPS and 39,5% in SAPS vs 18,6% in SLE, p=0,004 and p=0,04, accordingly). CI were predominantly organic origin in all patients, but vascular dementia was detected only among patients with APS (10,8% of PAPS and 3,03% of SAPS patients). There was no association of CI with clinical manifestations and SLE activity. In patients with PAPS CI was associated with stroke, livedo reticularis and lupus anticoagulant positivity. In 84 patients (74,3%) CI were also specifically bounded to MD. Current MD were detected in 100 (88,5%) patients: schizotypal disorder was found in 10 (8,85%) patients and was associated with PAPS (13,5% vs 9,09% in SAPS and 4,65% in SLE); anxiety-depressive spectrum disorders (ADDs) - in 95 (84,1%) (chronic and recurrent depression prevailed 37 (32,7%) and 42 (37,2%) resp.); the structure of MDs in accordance with ICI-10 differed slightly between groups, but no statistically significant differences were obtained.Conclusion:сognitive impairment, mainly of an organic type, are characteristic of most patients with SLE and APS. The significant associations of сognitive impairment with clinical manifestations and activity of SLE were not identified, but patients with сognitive impairments were more likely to have anxiety and depressive disorders, strokes, livedo reticularis and lupus anticoagulant positivityDisclosure of Interests:None declared
