Abstract
BACKGROUND AND PURPOSE Testing for antiphospholipid antibodies (aPL) is useful to determine the cause of ischemic stroke in young and female patients. However, the clinical relevance of aPL in older patients with ischemic stroke remains unclear. We aimed to explore the status and diagnostic value of initial aPL testing in all patients with acute ischemic stroke. METHODS We retrospectively analyzed patients with acute ischemic stroke who were consecutively hospitalized in our hospital between June 2012 and January 2022 and investigated the factors associated with performing aPL screening in real-world clinical practice. Furthermore, factors associated with initial aPL positivity were evaluated by comparing the demographic, etiological, and therapeutic characteristics. RESULTS Of 1209 patients, 287 (23.7%) were tested for aPL and 58 (20.2%) tested positive. Physicians tended to conduct aPL testing on female patients (P<0.001), younger patients (P<0.001), patients with fewer vascular risk factors (P<0.001), and multiple infarctions in the multivascular blood supply area (P<0.001). Multivariate logistic regression analysis showed that only stroke of other determined etiology type was a significant influencing factor for positive aPL results (OR 2.97, 95% CI 1.137, 7.774, P=0.026), adjusting for sex, age, and causes of stroke, etc. CONCLUSION: Approximately one-quarter of the patients with acute ischemic stroke were tested for aPL. Age, sex, number of vascular risk factors, and neuroimaging features affected the discretion in performing aPL testing. aPL testing may be appropriate in older patients with no identified cause of ischemic stroke and may provide additional diagnostic opportunities for acute ischemic stroke.

Abstract
Antiphospholipid antibodies (aPLs) are the leading causes of adverse pregnancy outcomes (APOs). We conducted cluster analysis to identify distinct phenotypes among aPLs-associated APOs patients. This approach aims to facilitate risk stratification and improve pregnancy outcomes for obstetric APS. This was a retrospective study of persistent aPLs positive women cohort in Peking Union Medical College Hospital. Baseline demographic characteristics, clinical manifestation, previous APOs and antibodies profiles were included for hierarchical cluster analysis. Placentae from portions of patients were collected and performed the histopathologic diagnoses. Four clusters among 209 patients with 477 pregnancies were identified. Cluster 1 comprised patients with triple aPLs positivity and demonstrates a high incidence of gestational hypertension (34.92%, P < 0.05) and preterm delivery (20.63%, P < 0.05). Patients in cluster 2 were characterized by lupus anticoagulant (LA) positivity, with high risk of whole gestational APOs. Cluster 3 included patients with isolated aPLs-IgM isotype combined with early miscarriage (60.92%, P = 0.016). Patients in cluster 4 majorly presented aPLs-IgG isotype combined with placenta insufficiency (22.73%). During the follow-up, the live birth rate in cluster 1 and 2 was only 69.20%. Placenta pathology revealed the most severe impairment within cluster 1, whereas clusters 3 and 4 exhibited relatively milder damage. By cluster analysis, we identified four clinical subtypes of aPLs-associated APOs patients. Patients with triple antibodies or high-risk lupus characteristics were prone to occurred gestational hypertension and premature delivery. Isolated LA or aCL/aβ2GPI positivity were found to be more frequently associated with early-stage fetal loss.

Abstract
INTRODUCTION Microvascular manifestations constitute a subtype of antiphospholipid syndrome, and those patients have relatively poor prognoses, so it is important to find markers for microvascular manifestations. This study was conducted to explore whether serum calprotectin could be a predictor of microvascular manifestations in antiphospholipid antibody (aPL)-positive patients. METHODS Consecutive patients with persistent aPL positivity referred to Peking Union Medical College Hospital and age- and sex-matched health controls (HCs) were included. Microvascular manifestations included antiphospholipid syndrome (APS) nephropathy, livedo reticularis, valvular lesions, non-stroke central nervous system manifestations, myocarditis, catastrophic APS, and other microvascular manifestations confirmed by pathology, imaging, or clinical diagnosis. Calprotectin was measured by an enzyme-linked immunosorbent assay (ELISA). The cutoff value was defined as mean + 2 standard deviations of HCs. Multivariable logistic regression analysis was used to analyze risk factors. Pearson correlation analysis was used to detect the correlation between calprotectin and other laboratory data. RESULTS Of the 466 patients included in the study, 281 (60.3%) patients met the 2006 Sydney Revised Classification Criteria; among the latter, 77.2% were patients with primary APS. The mean age was 39.10 ± 13.05 years old, and 77.0% were female. Thirty-eight age- and sex-matched HCs were included in the study. Serum calprotectin levels were increased in aPL-positive patients compared with HCs (649.66 ± 240.79 vs 484.62 ± 149.37 ng/ml, p < 0.001), and were increased in patients with microvascular manifestations compared with patients without (693.03 ± 271.90 vs 639.43 ± 232.06 ng/ml, p = 0.044). The cutoff value was 783.36 ng/ml. Ninety-three patients (20.0%) were positive for calprotectin. Calprotectin positivity was independently associated with microvascular manifestations (odds ratio [OR] 1.90, 95% confidence interval [CI] 1.07-3.36) and platelet count (PLT) < 100 (OR 2.04, 95% CI 1.08-3.88). Age (OR 0.98, 95% CI 0.96-1.00), systemic lupus erythematosus (OR 2.08, 95% CI 1.15-3.75), calprotectin positivity (OR 1.83, 95% CI 1.02-3.26), hypertension (OR 2.73, 95% CI 1.36-5.45), hemolytic anemia (OR 2.66, 95% CI 1.13-6.23), and anti-β2GPI antibodies (OR 2.06, 95% CI 1.11-3.83) could independently predict microvascular manifestations in aPL-positive patients. Serum calprotectin negatively correlated with PLT (R = - 0.101, p = 0.031). CONCLUSION Serum calprotectin levels are increased in aPL-positive patients and could be a potential predictor of microvascular manifestations.

Abstract
Anti-ovarian antibody (AOA) could be considered an independent marker for autoimmune ovarian disease and predicting future premature ovarian failure (POF). This study aims to investigate if AOA is associated with poor ovarian response (POR) and pro-inflammatory immune responses in women undergoing assisted reproductive technology (ART) cycles. Two hundred forty-eight women undergoing ART cycles were divided into four groups based on AOA test results and the presence of POR: POR(-)/AOA(-) group (N = 148), POR(+)/AOA(-) group (N = 34), POR (-)/AOA(+) group (N = 44), POR(+)/AOA(+) group (N = 22). The POR patients have a significantly higher prevalence of AOA than non-POR patients (P < 0.05). Peripheral blood CD56 + natural killer (NK) cell level (%), NK cytotoxicity, CD19 +CD5 + B-1 cell level (%), and IFN-γ/IL-10 producing T helper (Th) 1/Th2 cell ratios were significantly higher in POR(+)/AOA(+) group than those of other groups (P < 0.001, P < 0.005, P < 0.01, P < 0.05, respectively). TNF-α/IL-10 producing Th1/Th2 cell ratio of POR(+)/AOA(+) group was significantly higher than those of POR(+)/AOA(-) and POR(-)/AOA(-) groups (P < 0.05, respectively). Homocysteine and vitamin D levels of the POR(+)/AOA(+) group were significantly lower than those of other groups (P < 0.005, respectively). Plasminogen activator inhibiter-1 (PAI-1) level of POR(+)/AOA(+) group was significantly higher than that of POR(-)/AOA(-) group (P < 0.05). In the POR(+)/AOA(+) group, the prevalence of antiphospholipid antibodies was significantly higher than that of the POR(+)/AOA(-) group (P = 0.005). Women with autoimmune POR (POR(+)/AOA(+)) have dysregulated pro-inflammatory immune responses and metabolic factors. The diagnostic and therapeutic approaches for autoimmune POR should be differentiated from those for non-autoimmune POR.

Abstract
Antiphospholipid syndrome (APS) is a thromboinflammatory syndrome characterized by thrombotic, microvascular, obstetric, or non-thrombotic events in the setting of persistent antiphospholipid antibodies (aPL), namely anticardiolipin antibody (aCL), anti-β2 glycoprotein-I antibody (aβ2GPI), and lupus anticoagulant (LA). The diagnosis of APS requires careful assessment of the aPL profile, the clinical phenotype, and additional risk factors. The standard management of aPL-related thrombosis is anticoagulation, which is not effective for microvascular and non-thrombotic events. In parallel to our improved understanding of aPL-related mechanisms, the role of immunosuppression has been increasingly investigated. In this review, we summarize the basic concepts and future perspectives in APS.

Abstract
Tumor-selective viruses are a novel therapeutic approach for treating cancer. Tumor-Specific Immuno Gene Therapy (T-SIGn) vectors are tumor-selective adenoviral vectors designed to express immunomodulatory transgenes. Prolonged activated partial thromboplastin time (aPTT), associated with the presence of antiphospholipid antibodies (aPL), has been observed in patients with viral infections, and following administration of adenovirus-based medicines. aPL may be detected as lupus anticoagulant (LA), anti-cardiolipin (aCL) and/or anti-beta 2 glycoprotein antibodies (aβ2GPI). No subtype alone is definitive for development of clinical sequalae, however, patients who are 'triple positive' have a greater thrombotic risk. Additionally, isolated aCL and aβ2GPI IgM do not appear to add value in thrombotic association to aPL positivity, rather IgG subtypes must also be present to confer an increased risk. Here we report induction of prolonged aPTT and aPL in patients from eight Phase 1 studies who were treated with adenoviral vectors (n = 204). Prolonged aPTT (≥ Grade 2) was observed in 42% of patients, with a peak at 2-3 weeks post-treatment and resolution within ~ 2 months. Among patients with aPTT prolongation, LA, but not aCL IgG nor aβ2GPI IgG, was observed. The transience of the prolongation and discordance between positive LA and negative aCL/aβ2GPI IgG assays is not typical of a prothrombotic state. Among the patients with prolonged aPTT there was no evidence of an increased rate of thrombosis. These findings elucidate the relationship between viral exposure and aPL in the context of clinical trials. They suggest a framework in which hematologic changes can be monitored in patients receiving similar treatments.Clinical trial registration:NCT02028442, NCT02636036, NCT02028117, NCT03852511, NCT04053283, NCT05165433, NCT04830592, NCT05043714.

Abstract
OBJECTIVE Antiphospholipid antibodies (aPL) are related to poor pregnancy outcomes, but their effect on embryo implantation is unclear. We aimed to assess the prevalence of different aPL in women with recurrent implantation failure (RIF). METHODS We searched studies in PubMed (MEDLINE), Scopus and Cochrane Library. Quality of studies was scored by the Newcastle-Ottawa Scale and risk of bias assessment by items described in RevMan5 software. Statistical analyses were made using random-effects model and presented as pooled Odds Ratio (OR), 95% confidence interval (CI). Heterogeneity was assessed by I2% and D2%. RESULTS This systematic review and meta-analysis included 17 studies and showed a high degree of variability in aPL positivity in RIF. In the latter, the risk of bias assessment suggested unclear bias on study performance with a median sample size and interquartile range for RIF patients and fertile women of 96 (57-417) and 100 (60.5-202.5), respectively. Among the criteria aPL, IgG anticardiolipin autoantibodies (OR 5.02, 95% CI [1.95, 12.93]) were associated with RIF. Within the non-criteria aPL, anti-β2 glycoprotein I-IgA (OR 64.8, 95% CI [9.74, 431.0]), and antiphosphatidylglycerol-IgG and IgM (OR 10.74, 95% CI [5.25, 22.0]; OR 4.26, 95% CI [1.76,10.31]; respectively) were associated with RIF, too. CONCLUSIONS Anticardiolipin-IgG is a prevalent autoantibody in women with RIF. Three other non-criteria aPL, aβ2GP I-IgA, aPG-IgG and aPG-IgM also present a positive rate in RIF. Overall, these results advise about testing them as indicators of RIF risk in women seeking IVF treatment.

Abstract
We describe a 64-year-old Caucasian female with a history of Raynaud's disease, hand arthritis, photosensitivity, Sjogren's syndrome and leukocytoclastic vasculitis who presented with progressively worsening fingertip necrosis that began three days after receiving a first dose of Pfizer-BioNTech COVID-19 RNA vaccine. Our workup revealed cryoglobulinemia, hypocomplementemia, elevated antinuclear antibodies (ANA) and IgM antiphospholipid autoantibodies (aPL) directed against phosphatidylserine (aPL-PS), suggesting a diagnosis of systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). The patient failed to develop anti-spike IgG antibodies up to two months following vaccination. Disease progression was halted by plasmapheresis, anticoagulation, and immune suppression. We conclude that the vaccine RNA moiety may induce SLE manifesting in APS, cryoglobulinemia, hypocomplementemia, and digital necrosis.

Abstract
OBJECTIVE Unexplained recurrent miscarriage (uRM) has caused serious distress to women of childbearing age, and effective treatment is particularly important. The aim of this meta-analysis is to compare the efficacy of low molecular weight heparin (LMWH) and LMWH combined with aspirin for uRM. METHODS Databases including PubMed, Web of Science, Embase, Scopus and the Cochrane Library databases were electronically searched to identify randomized controlled trials that reported the LMWH or LMWH combined with aspirin for women with uRM and negative antiphospholipid antibodies (aPL). The retrieval time is limited from inception to June 2021. Two reviewers independently screened literature, extracted data, and assessed risk bias of included studies. Meta-analysis was performed by using STATA 12.0 software. RESULTS A total of 7 studies involving 1849 patients were included. The meta-analysis results showed that compared with the control group, both LMWH and LMWH + aspirin interventions showed no substantial influence on miscarriage rate (LMWH: RR = 0.69, 95%CI: 0.34-1.39, P = 0.293, LMWH + aspirin: RR = 0.62, 95%CI: 0.30-1.27, P = 0.19) and the occurrence of pre-eclampsia (LMWH: RR = 1.1, 95%CI: 0.53-2.31, P = 0.792; LMWH + aspirin: RR = 1.49, 95%CI: 0.25-8.79, P = 0.662). LMWH therapy had no influence on the live births (RR = 0.99, 95%CI: 0.92-1.06, P = 0.72). Subgroup analysis showed that enoxaparin is not effective in women with uRM and negative aPL (miscarriage rate: RR = 0.82, 95%CI: 0.31-2.19, P = 0.695; pre-eclampsia: RR = 1.03, 95%CI: 0.46-2.33, P = 0.936). CONCLUSIONS LMWH and LMWH combined with aspirin therapy cannot improve the pregnancy outcome of women with uRM and negative aPL. However, the above conclusions are still required to be verified through more RCTs due to the limited quantity of included studies.

Abstract
The presence of antiphospholipid antibodies was shown to be associated with thrombosis in coronavirus disease 2019 (COVID-19) patients. Recently, according to reports from several studies, the vaccine-induced immune thrombotic thrombocytopenia is mediated by anti-platelet factor 4 (PF4)-polyanion complex in adenovirus-vectored COVID-19 vaccine recipients. It is impendent to explore whether inactivated COVID-19 vaccine widely used in China influences prothrombotic autoantibody production and induces thrombosis. In this prospective study, we recruited 406 healthcare workers who received two doses, 21 days apart, of inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine (BBIBP-CorV, Sinopharm). Paired blood samples taken before vaccination and four weeks after the second vaccination were used in detecting prothrombotic autoantibodies, including anticardiolipin (aCL), anti-β2 glycoprotein I (aβ2GP1), anti-phosphatidylserine/prothrombin (aPS/PT), and anti-PF4-heparin. The seroconversion rate of SARS-CoV-2 specific antibodies was 95.81% (389/406) four weeks after vaccination. None of the subjects had spontaneous thrombosis or thrombocytopenia over a minimum follow-up period of eight weeks. There was no significant difference in the presence of all ten autoantibodies between samples collected before and after vaccination: for aCL, IgG (7 vs. 8, P = 0.76), IgM (41 vs. 44, P = 0.73), IgA (4 vs. 4, P = 1.00); anti-β2GP1, IgG (7 vs. 6, P = 0.78), IgM (6 vs. 5, P = 0.76), IgA (3 vs. 5, P = 0.72); aPS/PT IgG (0 vs. 0, P = 1.00), IgM (6 vs. 5, P = 0.76); aPF4-heparin (2 vs. 7, P = 0.18), and antinuclear antibody (ANA) (18 vs. 21, P = 0.62). Notably, seven cases presented with anti-PF4-heparin antibodies (range: 1.18–1.79 U/mL) after vaccination, and none of them exhibited any sign of thrombotic disorder. In conclusion, inactivated SARS-CoV-2 vaccine does not influence the profile of antiphospholipid antibody and anti-PF4-heparin antibody nor increase the risk of thrombosis.

Abstract
Objectives: The present meta-analysis aimed to assess the relationship between antiphospholipid antibodies (aPLs) or antiphospholipid antibody syndrome (APS) and the incidence of osteonecrosis (ON) in systemic lupus erythematosus (SLE) patients.Methods: MEDLINE/Pubmed, EMBASE, Web of science, the Chinese Biomedical Literature Database (CBM), the Wan-Fang Database, and the China National Knowledge Infrastructure (CNKI) were searched from their inception up until 26 December 2020. Studies in English were included. Case-control studies and cohort studies were included. Studies pertaining to the link between aPLs or APS and ON patients were slated for inclusion in the current analysis.Results: Twenty-two studies involving a total of 3054 SLE patients were included. The positivities of anticardiolipin antibody (ACL), IgG ACL, IgM ACL, LA and APS in SLE is not associated with ON. One study showed that IgG or IgM β2GP1 had no association with ON. No publication bias was detected. The quality of this evidence was low because of the high risk of bias across studies, and therefore robust inferences cannot be made.Conclusion: SLE patients demonstrated a weak association between aPLs and ON. The nature of the association between aPLs and ON in SLE needs to be investigated in-depth in future research.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by systemic involvement and multiple autoantibodies in the serum. Patients with protein C (PC) and protein S (PS) deficiency are prone to thrombosis. In contrast, patients with primary hyperfibrino-lysis tend to bleed.
CASE SUMMARY A 52-year-old female patient with bilateral pleural effusion was diagnosed with "tuberculous pleurisy" and treated with anti-tuberculosis drugs and prednisone. The coagulation-related laboratory results showed decreased fibrinogen, PC activity, PS activity, and antithrombin Ш activity. The immune-related laboratory results showed positive antinuclear antibody, anti-Smith antibody, anticardiolipin antibody (ACL), anti-β2-glycoprotein I antibody (aβ2GPI) and direct Coomb’s test and decreased complement 3 and complement 4. Thoracoscopy was performed and bloody pleural fluid was drained. Pathology of the pleural biopsy showed lymphocytes, plasma cells, and a few eosinophils in adipose and fibrous connective tissue. Results of whole exome sequencing of blood showed no genetic mutations suggesting the presence of hereditary hematological diseases. The patient was finally diagnosed with SLE and primary hyperfibrinolysis, and was treated with prednisolone, hydroxychloroquine, and compound cyclophosphamide.
CONCLUSION PC and PS deficiency in SLE might be related to ACL and aβ2GPI. SLE and primary hyperfibrinolysis can coexist in one patient, with both a risk of thrombosis and a risk of bleeding.

Abstract
BACKGROUND AND PURPOSE Antiphospholipid syndrome (APS) is one of the uncommon causes of ischemic stroke, and is associated with young and female patients. However, the significance of antiphospholipid antibody (aPL) in older ischemic stroke patients is uncertain. We aimed to examine the significance of aPLs in ischemic stroke in these older patients. MATERIALS AND METHODS A total of 739 patients with acute ischemic stroke within 7 days of initial symptoms were collected consecutively. Clinical and laboratory data were obtained from medical records. aPLs (lupus anticoagulant, anti-cardiolipin antibody, anti-β2glycoprotein-I antibody) were measured the day after admission and the presence of at least one antibody was regarded as positive aPL. Patients with positive aPL were rechecked after at least 12 weeks for confirmation of APS. RESULT Of the 739 patients, 103 (13.9%) had at least one aPL initially. These patients were older, had more atrial fibrillation and higher levels of inflammatory markers. Among the 103 aPL positive patients, 41 remained positive at 3 months, 23 showed negative conversion, and 39 were not available for follow-up. Patients diagnosed with APS had higher numbers of aPL and had specifically anti-β2glycoprotein-I IgG antibody. The patients with aPLs did not differ significantly from the others in terms of stroke subtype. CONCLUSION aPL was rather common in ischemic stroke patients regardless of age. Although the influence of transient positive aPL on ischemic stroke remains uncertain, two or more aPLs and the presence of anti-β2glycoprotein-I IgG may predict a diagnosis of APS.

Abstract
Immunopathology may play a significant role in the pathogenesis of Coronavirus-Induced Disease-19 (COVID-19). Immune-mediated tissue damage could result from development of rapid autoimmune responses, characterized by production of self-reactive autoantibodies. In this study, we tested specimens from acutely ill patients hospitalized with COVID-19 for autoantibodies against nuclear, vasculitis-associated, and phospholipid antigens. Detectable autoantibodies were present in 30% of the patients in our cohort, with the majority of reactive specimens demonstrating antibodies to nuclear antigens. However, antinuclear antibodies were only weakly reactive and directed to single antigens, as is often seen during acute infection. We identified strongly reactive antibodies to nuclear antigens only in patients with a prior history of autoimmune disease. In our cohort, the prevalence of antiphospholipid antibodies was low, and we did not detect any vasculitis-associated autoantibodies. We found similar levels of inflammatory markers and total immunoglobulin levels in autoantibody positive versus negative patients, but anti-SARS-CoV-2 antibody levels were increased in autoantibody positive patients. Together, our results suggest that acute COVID-19 is not associated with a high prevalence of clinically significant autoantibody responses of the type usually associated with autoimmune rheumatic disease. Autoantibodies against nuclear antigens are detectable in 25% of patients hospitalized with acute COVID-19. Anti-nuclear antigen antibodies were weakly reactive and most often directed to single antigens. Vasculitis-associated autoantibodies were not detected in specimens from patients with acute COVID-19. Anti-phospholipid antibodies were infrequently detected in patients with acute COVID-19.

Abstract
The outbreak of novel coronavirus disease 2019 (COVID-19) has now become a global pandemic. Coagulopathy has been reported widely in critically ill COVID-19 patients and was related to high mortality. However, the comprehensive coagulation profiles have not been examined and the underlying mechanism of the coagulopathy in COVID-19 patients is unclear. To study the coagulation profiles of routine hemostasis tests, natural anticoagulants, coagulant factors and antiphospholipid antibodies in critically ill COVID-19 patients. This single-center and cross-section study included 19 patients with COVID-19, who were admitted to intensive care unit (ICU) at Tongji hospital in Wuhan, China, from Feb 23 to Mar 3, 2020. Demographic data, laboratory parameters, treatments and clinical outcomes of the patients were collected and analyzed. The final date of follow-up was Mar 31, 2020. In this study, 12 thrombotic events occurred in 9 patients, including 4 cerebral infarctions, 7 acro-ischemia and 1 internal jugular vein thrombosis. The common abnormalities of routine coagulation tests included evelated D-Dimer level (100%), prolonged prothrombin time (73.7%) and hyperfibrinogenemia (73.7%). The median activities of natural anticoagulants including protein C, protein S and antithrombin were all below the normal range. Factor VIII activities were significantly above normal range (median value 307%, IQR 198–441) in all patients. Factor V and factor VII activities were significantly lower in near-terminal stage patients. Anti-phospholipid antibodies were present in 10 patients. Strikingly, 4 cerebral infarction events were in patients had anti-phospholipid antibodies of multiple isotypes. Sustained hypercoagulable status and thrombotic events were common in critically ill patients with COVID-19. The low activities of natural anticoagulants, elevated factor VIII level and the presence of antiphospholipid antibodies, together, may contribute to the etiopathology of coagulopathy in COVID-19 patients.

Abstract
BACKGROUND Anti-phospholipid antibodies (aPL) have been reported to be associated with repeated implantation failure (RIF), but the mechanism remains controversial. Endometrial receptivity is well known to be crucial for embryo implantation. This study aims to investigate the effect of aPL on endometrial receptivity in RIF women with positive aPL. METHODS Sixty-four infertile women with normal menstrual cycles were enrolled. The control group comprised 32 pregnant women with negative aPL who conceived successfully after their first in vitro fertilization-embryo transfer (IVF-ET) cycle, and the RIF group comprised 32 women with positive aPL. Endometrial biopsy samples were collected seven days after the luteinizing hormone surge (LH + 7). The expression of LIF and HOXA10 was evaluated by immunohistochemistry, qRT-PCR and Western blot. Endometrial pinopode development was examined by scanning electron microscopy. RESULTS The mRNA expression of LIF and HOXA10 in the RIF group was significantly decreased compared with that in the control group during the implantation window. The immunohistochemistry and Western blot results confirmed these findings. Then, ultrastructural analyses of endometrial cells showed fewer pinopode processes, a more atypical morphology and increased atrophy in the RIF group compared with the control group, and these results were statistically significant. CONCLUSION aPL positivity may inhibit the expression of LIF and HOXA10 in the endometrium and influence pinopode development. Our findings suggest that positivity for aPL is associated with impaired endometrial receptivity, which results in the development of RIF.

Abstract
INTRODUCTION Antiphospholipid antibodies (aPL) have been associated with organ damage and certain features in systemic lupus erythematosus(SLE) patients. Our aim was to investigate the differences between SLE patients according to the presence of aPL and/or clinical antiphospholipid syndrome (APS). MATERIALS AND METHODS Patients from the RELESSER-T registry were included. RELESSER-T is a Spanish multicenter, hospital-based, retrospective, SLE registry. RESULTS We included 2398 SLE patients, 1372 of whom were positive for aPL. Overall 1026 patients were classified as SLE, 555 as SLE-APS and817 as SLE-aPL. Regarding cardiovascular risk factors, SLE-APS patients had higher rates of hypertension, dyslipidemia and diabetes than those with SLE-aPL and SLE (p < 0.001). SLE-APS patients showed higher rates of neuropsychiatric, cardiac, pulmonary, renal and ophthalmological manifestations than the other groups (p < 0.001). SLE-APS patients presented greater damage accrual with higher SLICC values (1.9 ± 2.2 in SLE-APS, 0.9 ± 1.4 in SLE-aPL and 1.1 ± 1.6 in SLE, p < 0.001) and more severe disease as defined by the Katz index (3 ± 1.8 in SLE-APS, 2.7 ± 1.7 in SLE-aPL and 2.6 ± 1.6 in SLE, p < 0.001). SLE-APS patients showed higher mortality rates (p < 0.001). CONCLUSIONS SLE-APS patients exhibited more severe clinical profiles with higher frequencies of major organ involvement, greater damage accrual and higher mortality than SLE-aPL and SLE patients.

Abstract
Background Specific anti-phospholipids antibodies (aPLs) are used as classification criteria of the antiphospholipid syndrome (APS). These aPLs, although essential for diagnosis, do not predict disease phenotypes, which may require specific therapies. Non-criteria aPLs are rarely evaluated and their role is yet to be defined. In the current study, we aimed to examine the association between criteria and non-criteria aPLs and APS phenotypes. Methods Serum samples from 188 subjects, 130 APS patients and 58 controls were analyzed for the presence of 20 aPLs (IgG and IgM isotypes to cardiolipin (CL), beta2-glycoprotein1 (β2GP1), phosphatidic acid (P-acid), phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), phosphatidylinositol (PI), phosphatidylserine (PS), annexin-5 (AN) and prothrombin (PT) using a line immunoassay (GA Generic Assays, Germany). Sero-positivity to the different aPLs/aPLs profiles was correlated to APS phenotypes (i.e. arterial thrombosis, CNS manifestations, venous thrombosis, relapsing disease, obstetric morbidity). Results In this cohort, arterial thrombosis was associated with accumulative number of ≥ 7/20 aPLs evaluated (OR 4.1; CI 95% 1.9–96, p = 0.001) as well as the sole presence of aPT (IgG) (OR 2.3;CI 95% 1.1–5.1, p = 0.03). CNS manifestations were linked with a profile of 4 aPLs (IgG): aPT, aPG, aPI and aAN (OR 2.6;CI 95% 1.1–6.3, p = 0.03). Symptom-free period of ≥ 3 years was linked with lower number of aPLs and the presence of aPI (IgG) (OR 3.0;CI 95% 1.08–8.1, p < 0.05) or aAN (IgG) (OR 3.4;CI 95% 1.08–10.9, p < 0.05). APS related pregnancy morbidity correlated with a profile of 2 aPLs (IgG): aCL and aPS (OR 2.9; CI 95% 1.3–6.5, p < 0.05) or the sole presence of aAN (IgG) (OR 2.8; CI 95% 1.02–8, p = 0.05). Conclusion In this study, we observed an association between specific criteria/non-criteria aPLs or aPLs profiles and clinical phenotypes of APS. Our data suggest that examination of a wider variety of aPLs may allow better characterization of APS.

Abstract
Appropriate contraception and preconception counseling are critical for women of reproductive age with systemic autoimmune diseases (AIDs) because clinical diagnosis, rheumatology medications, and disease activity may impact the safety or efficacy of certain contraceptives as well as the risk of adverse pregnancy outcomes. The presence of antiphospholipid (aPL) antibodies (anticardiolipin, anti-β2 glycoprotein I, and lupus anticoagulant) is the most important determinant of contraception choice, as women with these antibodies should not receive estrogen-containing contraceptives because of the increased risk of thrombosis. Prepregnancy counseling generally includes the assessment of preexisting disease-related organ damage, current disease activity, aPL antibodies, anti-Ro/SS-A and anti-La/SS-B antibodies, and medication safety in pregnancy. Quiescent AID for six months on pregnancy-compatible medications optimizes maternal and fetal/neonatal outcomes for most patients.

Abstract
Antiphospholipid antibodies (aPLs) are a group of autoantibodies that target phospholipids and/or phospholipid-binding proteins. aPLs are important serum markers of anti phospholipid syndrome and are also risk factors for thrombosis and pathological pregnancy. Standardization of aPLs detection is critical to its clinical application.

Abstract
AIM We investigated whether persistent antiphospholipid syndrome (APLAs) at diagnosis are associated with the risk of thrombotic events during follow-up in patients with ANCA-associated vasculitis (AAV). METHODS We retrospectively reviewed the medical records of 138 AAV patients. Thrombotic events were defined as arterial and venous thrombosis confirmed by magnetic resonance imaging, computed tomography, angiography and Doppler ultrasonography. Clinical and laboratory variables at diagnosis and during follow-up between patients with and without thrombotic events were compared. The univariable and multivariable Cox hazard model analyse to appropriately obtain hazard ratio (HR) considering the follow-up duration were conducted. RESULTS The mean age of 138 AAV patients was 55.1 years and 44 were male. Persistent APLAs were detected in 18 patients with AAV (13.0%). Thrombotic events were observed in 26 patients with AAV (18.8%) during follow-up. At the time of a retrospective study point, persistent APLAs at diagnosis were observed more frequently in patients with thrombotic events than those without. In the multivariable Cox hazard model analysis, age at diagnosis (HR 1.075) and persistent APLAs (HR 2.902), but not ANCAs. Thrombotic events were identified more frequently in patients with persistent APLAs at diagnosis than those without (38.9% vs. 15.8%, relative risk 3.383). CONCLUSION Persistent APLAs at diagnosis are significantly associated with the risk of thrombotic events during follow-up of AAV. We suggest that physicians should closely monitor the development of thrombotic events during follow-up.

Abstract
BACKGROUND No absolute data on the treatment of antiphospholipid antibodies (aPL) related to refractory obstetric complications exist to date. TNF-α play a major role in this disorder. OBJECTIVE To assess the effectiveness of TNF-α blockers in 18 aPL-positive women with recurrent infertility after therapy with low-molecular-weight heparin (LMWH) plus aspirin (LDA) plus hydroxychloroquine (HCQ). METHODS Prospective case-series of 12 women fulfilling Sydney criteria for obstetric antiphospholipid syndrome (OAPS) and 6 with incomplete forms (OMAPS). All women tested positive for aPL at least twice. Non-criteria aPL were tested in 15/18. Complement, TNF-α and IL-10 were also evaluated. Women were closely monitored for fetal well-being and possible malformations throughout gestation and the postpartum period. RESULTS Sixteen patients were started on adalimumab and 2 on certolizumab. Twelve women completed gestation: 9 at term and 3 pre-term. Differences in laboratory categories and outcomes were observed when OAPS and OMAPS were compared. First trimester miscarriage or implantation failure recurred in 6 cases, all of the OAPS group. Malformations were not seen in the newborns. CONCLUSIONS Overall, good obstetric results were obtained in 70% of previous LMWH-LDA+HCQ refractory cases. TNF-α blockers were well tolerated without adverse effects. The combination of LMWH plus LDA plus TNF-α blockers appears to be a promising treatment for refractory obstetric complaints related to aPL; nevertheless, outcome differences between OAPS and OMAPS do exist.

Abstract
Women with antiphospholipid antibodies (aPL) are at high risk for pregnancy complications, such as preeclampsia. We previously demonstrated that aPL recognizing β2GPI promote an extravillous trophoblast pro-inflammatory, anti-migratory and anti-angiogenic profile similar to that seen in preeclampsia. Since preeclampsia in the absence of aPL may have an underlying infectious element, women with aPL may be at increased risk for preeclampsia or other adverse outcomes if an infection is present. Our objective was to determine the impact the common bacterial component, muramyl dipeptide (MDP), has on trophoblast responses to aPL. Herein, we report that bacterial MDP amplifies trophoblast IL-1β expression, processing, and secretion in the presence of aPL through activation of NOD2. In the absence of MDP, NOD2 also mediates anti- β2GPI antibody-induced trophoblast IL-1β and VEGF secretion. Additionally, we report a role for extravillous trophoblast vimentin as a novel danger signal that contributes to the aPL-induced trophoblast IL-1β production. Together our data indicate that NOD2 mediates trophoblast inflammatory and angiogenic responses to aPL alone, and mediates trophoblast inflammation in the presence of bacterial MDP. These findings suggest that a bacterial infection at the maternal-fetal interface may exacerbate the impact aPL have on trophoblast inflammation and, thus, on pregnancy outcome.

Abstract
An association between autoimmune events, as well as the development of antiphospholipid (aPL) antibodies and lymphoproliferative disorders is well recognized. We present the patient with coagulation abnormalities and non-Hodgkin lymphoma (NHL), primarily diagnosed as nodal marginal zone B-cell lymphoma (NMZL), and in relapse as diffuse large B-cell lymphoma (DLBCL). In the follow-up period, the patient simultaneously developed different aPL antibodies. The presence of aPL antibodies in NHL is frequent but it is not common in the NMZL. The aim of the present case report is to highlight the possible underlying increase of aPL antibodies in NMZL patients with coagulation tests abnormalities.

Abstract
As the clinical symptoms of the antiphospholipid syndrome (APS) frequently occur irrespective of the syndrome, diagnosis predominantly depends on the laboratory assays measuring the level or function of antiphospholipid antibodies (aPLs). β2-glycoprotein I (β2GPI) is increasingly accepted as the most important target of aPLs. Anti-β2GPI antibodies constitute a heterogeneous population, but current in vivo and in vitro evidence show that especially the first domain (DI) of β2GPI contains an important pathogenic epitope. This epitope containing Glycine40-Arginine43 (G40-R43) has proven to be cryptic and only exposed when β2GPI is in its open conformation. A previous study demonstrated a highly variable exposure of the cryptic epitope in commercial anti-β2GPI assays, with implications on correct patient classification. Unexpectedly, recent unpublished data revealed impaired exposure of the pathogenic epitope in the commercially available anti-DI chemiluminescence immunoassay (CIA) assay detecting specific antibodies directed to DI. In this review we summarize the laboratory and clinical performance characteristics of the different anti-DI assays in published data and conclude with inconsistent results for both the correlation of anti-DI antibodies with clinical symptoms and the added value of anti-DI antibodies in the classification criteria of APS. Additionally, we hypothesize on possible explanations for the observed discrepancies. Finally, we highly advise manufacturers to use normal pooled plasma spiked with the monoclonal anti-DI antibodies to verify correct exposure of the cryptic epitope.

Abstract
In this study, we investigated four patients who met the diagnostic criteria for overlapping systemic lupus erythematosus (SLE) and myasthenia gravis (MG) but responded differently to treatment. All patients were acetylcholine receptor (AChR) and antinuclear antibody positive at the time of SLE diagnosis. Two patients presented with SLE who have been effectively treated with cholinesterase inhibitors for MG. These patients developed SLE with photosensitivity, rash, and arthritis post thymectomy, which had been performed 29 years and 40 years earlier, respectively. Two other patients were found to have AChR antibodies and MG in the context on new-onset SLE. These subjects were responsive to hydroxychloroquine and immunosuppression but failed cholinesterase inhibitors. The evolution of these cases is relevant for the role of thymus in lupus pathogenesis during aging and for treatment selection in SLE-MG overlap patients.

Abstract
Testing for antiphospholipid antibodies could be an important part in determining the cause of a cerebrovascular event (CVE). Currently, it is also unknown whether antiphospholipid antibodies represent a risk factor for the development of a CVE and whether the selected therapy options are efficacious. So, this study aimed at (1) determining the frequency of patients experiencing a CVE and fulfilling the laboratory criterion for an antiphospholipid syndrome (APS), (2) investigating whether the persistent presence of antiphospholipid antibodies represented a risk factor for a CVE, and (3) focusing on the efficacy of the selected treatment strategy in the first year after the CVE. Eighty-nine patients with an acute CVE were prospectively followed for 1 year. At least two sera from each were tested for lupus anticoagulants, anticardiolipin, anti-β2-glycoprotein I, anti-phosphatidylserine/prothrombin and anti-annexin V antibodies. Twenty out of eighty-nine (22%) of CVE patients fulfilled the criteria for APS (17/20 for definitive and 3 for probable APS). There was a significant association between persistently present antiphospholipid antibodies and the CVE (OR, 4.62). No statistically significant difference was found in the CVE recurrence rate between APS-CVE and non-APS-CVE patients being treated mainly with acetyl salicylic acid. Antiphospholipid antibodies represent an independent risk factor for a CVE. In the first year after the CVE, antiplatelet therapy seemed to be sufficient in secondary CVE thromboprophylaxis in most APS patients.

Abstract
BACKGROUND Autoimmunity is believed to play an important causative role in the pathogenesis of epilepsy. There are evidences for the presence of autoantibodies in patients with epilepsy. To date, many studies have assessed the presence of antiphospholipid antibodies (aPLs) in epilepsy patients, though the relationship has been inconclusive. AIMS The aim of this systematic review and meta-analysis was to evaluate the presence of aPLs in epileptic patients as compared to healthy controls. METHODS Five electronic databases (PubMed, Web of Science, Embase, Scopus and Google Scholar) were searched systematically. Study-specific odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effects model. Quality assessment was carried out by using the modified 9-star Newcastle-Ottawa Scale (NOS). L'Abbé plots were generated to visually inspect heterogeneity while publication bias was evaluated via visualization of contour- enhanced funnel plots, and Begg's and Egger's tests. RESULTS Based on the inclusion criteria, 14 studies were selected involving 1248 epilepsy patients and 800 healthy controls. The majority of epilepsy was categorised as generalised or partial and none had comorbidity with autoimmune diseases. Significant presence of both anticardiolipin (aCL) antibodies (OR: 5.16, 95% CI: 3.21-8.28, p < 0.00001) and anti-β2- glycoprotein I (anti-β2-GPI) antibodies (OR: 2.95, 95% CI: 1.07-8.11, p = 0.04) exhibited comorbid association with epilepsy patients as compared to healthy controls. Subgroup analyses revealed that presence of aCL antibodies was more specifically observed in paediatrics (OR: 4.57, 95% CI: 2.57-8.15, p < 0.00001) than adults (OR: 4.24, 95% CI: 1.80-10.01, p = 0.001). The odds of aCL antibody presence was higher in partial epilepsy patients (OR: 7.88, 95% CI: 3.23-19.24, p < 0.00001) than that of generalised (OR: 3.76, 95% CI: 2.15-6.59, p < 0.00001) and in Asian epileptic patients (OR: 9.56, 95% CI: 2.69-33.95, p = 0.0005) than Europeans (OR: 4.35, 95% CI: 2.74-6.92, p < 0.00001). The presence of anti-β2-GPI antibodies was significant in paediatric (OR: 6.44, 95% CI: 1.39-29.89, p = 0.02) and African population with epilepsies (OR: 10.59, 95% CI: 1.22-92.25, p = 0.03). NOS of the majority of the studies (11/14) indicated a high methodological quality. No substantial heterogeneity was observed either from the quantitative analysis or from the L'Abbé plots while no significant publication bias was detected from funnel plots; Begg's and Egger's tests. CONCLUSION Since none of the epilepsy subjects exhibited any comorbid autoimmune disorders, significant presence of aCL and anti-β2-GPI antibodies indicate towards their contribution in immune-mediated general pathogenesis of epilepsy.

Abstract
BACKGROUND AND OBJECTIVES Concomitant neurologic manifestations and positive antiphospholipid antibodies (APAs) have been investigated in different manners. The present study aimed to investigate the association between neurologic manifestations and APAs. MATERIALS AND METHODS This cross-sectional descriptive study was conducted on 100 consecutive patients with selected neurological manifestations and at least one positive APAs within the age range of 20-50 years, referred to the Rheumatic Diseases Research Center from the Northeast Central Neurology Department of Iran during August 2012 to March 2014. RESULTS According to the results, 89% of the participants were persistently positive for APAs, including lupus anticoagulant, IgG anticardiolipin (aCL), IgM aCL, IgG β-2 glycoprotein 1 (β2- GP1), and IgM β2-GP1, observed in 16%, 41%, 42%, 17%, and 15% of the patients, respectively. Furthermore, 10% of the patients had concomitant lupus manifestations, and 37% of them showed anti-DNA. The IgG and IgM aCL were the most prevalent antibodies. Cerebral vascular accident (33%), retinal artery/vein occlusion (21%), and seizure (20%) were the most frequent presentations among the patients. In addition, the patients with multiple sclerosis (composing 3% of the subjects) were 100% positive for IgG and IgM aCL, as well as lupus anticoagulant. In addition, IgM anti-β2- GP1 was 100% positive in optic neuritis patients (composing 5% of the subjects) and was significantly associated with this neurologic disorder. IgM anti-β2-GP1 was also prevalent in the cases with Guillain-Barré syndrome. The most prevalent persistently positive antibody in the patients with cerebrovascular accident was IgM aCL. CONCLUSION The findings of this study revealed some associations between the subtypes of APAs and incidence of neurologic disorders. However, the exact correlation between those symptoms and APAs needs further investigations.

Abstract
Objective To investigate prevalence of antiphospholipid antibody (APA) in Korean infertile women undergoing the first in vitro fertilization (IVF) treatment and to evaluate the influence of APA on the subsequent IVF outcomes. Method Two hundred nineteen infertile women who destined the first IVF were prospectively enrolled in 2 infertility centers. Male factor or uterine factor infertility and women with past or current endocrine or immunologic disorders were completely excluded. Plasma concentration of lupus anticoagulant was measured by clot-based method, and anticardiolipin antibody (IgG/IgM), and anti-β2-glycoprotein 1 antibody (IgG/IgM) was measured by enzyme-linked immunosorbent assay method before starting ovarian stimulation for IVF. Results APA was positive in 13 women (5.9%). Lupus anticoagulant was positive in 2 women (0.9%), anticardiolipin antibody was positive in 7 women (3.2%), and anti-β2-glycoprotein 1 antibody was positive in 4 women (1.8%). In 193 women entering embryo transfer, clinical characteristics and stimulation outcomes were comparable between APA-positive (n=12) and APA-negative group (n=181). The clinical pregnancy rate (66.7% vs. 45.9%), ongoing pregnancy rate (58.3% vs. 37.0%), and miscarriage rate (12.5% vs. 19.3%) were all similar between APA-positive and APA-negative group. Conclusion The prevalence of APA is low in Korean infertile women undergoing the first IVF cycle, and the presence of APA appears to neither decrease their first IVF success nor increase abortion rate.

Abstract
BACKGROUND AND OBJECTIVES To compare clinical, laboratory, treatment and live birth rate data between women with aPL-related obstetric complications (OMAPS) not fulfilling the Sydney criteria and women fulfilling them (OAPS). MATERIALS AND METHODS Retrospective and prospective multicentre study. Data comparison between groups from The European Registry on Antiphospholipid Syndrome included within the framework of the European Forum on Antiphospholipid Antibody projects. RESULTS 338 women were analysed: 247 fulfilled the Sydney criteria (OAPS group) and 91 did not (OMAPS group). In the OMAPS group, 24/91 (26.37%) fulfilled laboratory Sydney criteria (subgroup A) and 67/91 (74.63%) had a low titre and/or non-persistent aPL-positivity (subgroup B). Overall, aPL laboratory categories in OAPS vs. OMAPS showed significant differences: 34% vs. 11% (p<0.0001) for category I, 66% vs. 89% (p<0.0001) for category II. No differences were observed when current obstetric complications were compared (p=0.481). 86.20% of OAPS women were treated vs. 75.82% of OMAPS (p=0.0224), particularly regarding the LDA+LMWH schedule (p=0.006). No differences between groups were observed in live births, gestational, puerperal arterial and/or venous thrombosis. CONCLUSIONS Significant differences were found among aPL categories between groups. Treatment rates were higher in OAPS. Both OAPS and OMAPS groups had similarly good foetal-maternal outcomes when treated. The proposal to modify OAPS classification criteria, mostly laboratory requirements, is reinforced by these results.

Abstract
PURPOSE International consensus criteria for antiphospholipid syndrome (APS) require persistently positive antiphospholipid antibodies (aPL) and medium or high titers in association with clinical manifestations. However, the clinical relevance of persistence and titers of aPL in patients with stroke has not been identified. We aimed to investigate the risk of subsequent thrombotic events in patients with ischemic stroke with aPL positivity in terms of aPL status. MATERIALS AND METHODS We reviewed the medical records of 99 patients with ischemic stroke with at least one or more aPL-positivity (i.e., positivity for aCL, anti-β2-glycoprotein-1, and/or lupus anticoagulants). The patients were divided into two groups: "definite APS" who fulfilled the laboratory criteria and "indefinite APS" who fell short of the criteria. We compared the risk of subsequent thrombotic events between the two groups. Cox proportional hazards model and Kaplan-Meier survival curves were used for the analyses. RESULTS Of the 99 patients, 46 (46%) were classified as having definite APS and 53 (54%) as having indefinite APS. The mean follow-up was 51.6 months. Overall event numbers were 14 (30.4%) in definite APS and 16 (30.2%) in indefinite APS. Increased subsequent thrombotic events (hazard ratio 1.039; 95% confidence interval 0.449-2.404; p=0.930) and decreased time to thrombotic events (log-rank p=0.321) were not associated with aPL status. CONCLUSION There was no increased risk of subsequent thrombotic events in ischemic stroke patients with definite APS, compared with those with indefinite APS.

Abstract
Objectives The aim of this study was to investigate the association between antiphospholipid antibodies and non-thrombotic and non-gestational manifestations of systemic lupus erythematosus. Methods Systemic lupus erythematosus patients with persistently positive antiphospholipid antibodies or lupus anticoagulant were identified and grouped as systemic lupus erythematosus with antiphospholipid syndrome (SLE-APS), systemic lupus erythematosus with positive antiphospholipid antibodies/lupus anticoagulant without antiphospholipid syndrome (SLE-aPL), and systemic lupus erythematosus with negative aPLs (SLE-No aPL). Groups were compared in terms of non-thrombotic systemic lupus erythematosus manifestations and laboratory features retrospectively. Results A total of 150 systemic lupus erythematosus patients, 26 with SLE-APS, 25 with SLE-aPL, and 99 with SLE-No aPL, were identified. Livedo reticularis, neurologic involvement, and thrombocytopenia were more common in antiphospholipid antibody positive systemic lupus erythematosus cases. Malar rash, arthritis, and pleuritis were more common in the SLE-No aPL, SLE-APS, and SLE-aPL groups, respectively. Positivity rates and titers of specific antiphospholipid antibodies did not differ between the SLE-APS and SLE-aPL groups. Conclusions Presence of antiphospholipid syndrome or persistent antiphospholipid antibodies may be related to non-thrombotic and non-gestational systemic lupus erythematosus manifestations. Patients with systemic lupus erythematosus plus antiphospholipid syndrome and persistent antiphospholipid antibodies without antiphospholipid syndrome also differ in terms of systemic lupus erythematosus manifestations.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune condition that is associated with thrombosis and morbidity in pregnancy. The exact mechanisms by which these associations occur appear to be heterogeneous and are not yet well understood. The aim of this study was to identify and analyze publications in recent years to better understand the diagnosis and its contribution to monitoring APS among women with recurrent miscarriage (RM). This systematic review and meta-analysis was conducted using the PubMed and Web of Knowledge databases, with articles published between 2010 and 2014, according to the PRISMA statement. Of the 85 identified studies, nine were selected. Most of the studies reported an association between recurrent miscarriage and specific antiphospholipid antibodies, as anticardiolipin antibodies (aCL), lupus anticoagulant (LA), anti-β2-glycoprotein I antibodies (aβ2GPI) and antiphosphatidylserine (aPS), which showed a relationship with RM. The main result of the meta-analysis revealed association between antiphospholipid antibodies (aPLs) and/or APS compared to the patients with RM (OR: 0.279; 95% CI: 0.212-0.366) and APS cases compared to the patients with RM (OR: 0.083; 95% CI: 0.036-0.189). High heterogeneity among these studies (I2=100.0%, p <0.001) was observed. In addition, there was no significant publication bias across studies according to Begg's test (p=0.230), although Egger's test (p=0.037) suggests significant publication bias. The funnel plot was slightly asymmetrical. Systematic review and meta-analysis demonstrated a positive association between antiphospholipid antibodies and/or antiphospholipid syndrome in patients with recurrent miscarriage.

Abstract
BACKGROUND Sickle cell anemia (SCA) is characterized by abnormally shaped, adhesive RBCs that interact with white blood cells and the endothelium, leading to chronic hemolysis, vasculopathy and a prothrombotic state. About 10% of subjects with a thrombotic event in the general population will have an associated antiphospholipid (aPL) antibody. One proposed mechanism for the thrombophilic nature of aPL antibodies is the disruption of the potent anticoagulant annexin A5 or Annexin A5 resistance (A5R). We designed a pilot study assessing the presence of aPL antibodies and disruption of A5R in pediatric sickle cell subjects. METHODS 39 subjects with SCA participated in this study. A5R, DRVVT, anti-β2GP1, anti-β2GP1, anti-phosphatidylserine and anti-cardiolipin antibody assays were performed. RESULTS There was a high prevalence of abnormal A5R despite a low prevalence of antiphospholipid antibodies. Multivariate logistic regression analyses showed an association with silent infarcts (p=0.015), lower hemoglobin (p=0.037), older age (p=0.047) and abnormal A5R. CONCLUSION We report an association between annexin A5 resistance and presence of silent infarct, low hemoglobin, and older age in a subgroup of SCA subjects. A potential role for perturbed A5R in the pathophysiology of SCA needs to be evaluated further.

Abstract
Antiphospholipid syndrome (APS) is characterized by thrombosis and/or pregnancy complications in the presence of persistent antiphospholipid antibodies (APLA). Laboratory diagnosis of APLA depends upon the detection of a lupus anticoagulant, which prolongs phospholipid-dependent anticoagulation tests, and/or anticardiolipin (aCL) and anti-β2-glycoprotein-1 (β2GPI) antibodies. APLA are primarily directed toward phospholipid binding proteins. Pathophysiologic mechanisms underlying thrombosis and pregnancy loss in APS include APLA induced cellular activation, inhibition of natural anticoagulant and fibrinolytic systems, and complement activation, among others. There is a high rate of recurrent thrombosis in APS, especially in triple positive patients (patients with lupus anticoagulant, aCL and anti-β2GPI antibodies), and indefinite anticoagulation with a vitamin K antagonist is the standard of care for thrombotic APS. There is currently insufficient evidence to recommend the routine use of direct oral anticoagulants (DOAC) in thrombotic APS. Aspirin with low molecular weight or unfractionated heparin may reduce the incidence of pregnancy loss in obstetric APS. Recent insights into the pathogenesis of APS have led to the identification of new potential therapeutic interventions, including anti-inflammatory and immunomodulatory therapies. Additional research is needed to better understand the effects of APLA on activation of signaling pathways in vascular cells, to identify more predictive biomarkers that define patients at greatest risk for a first or recurrent APLA-related clinical event, and to determine the safety and efficacy of DOACs and novel anti-inflammatory and immune-modulatory therapies for refractory APS.

Abstract
The study aims to analyse the clinical and immunological manifestations of paediatric antiphospholipid syndrome (APS) in patients, based on the 2006 revised classification criteria of definite APS. Fifty-eight paediatric patients with APS were enrolled and analysed retrospectively. A total of 37 female and 21 male patients with a mean age of 14 ± 3 years at disease onset were included. Fourteen (24%) cases were primary APS, and 40 (69%) cases were secondary to systemic lupus erythaematosus (SLE). Anti-nuclear antibody (ANA) positivity and hypocomplementemia were more common in secondary APS than in primary APS. The most common manifestations of thrombosis were deep vein thrombosis of the lower extremities (25 cases, 37%). Non-thrombotic manifestations were mainly immunologic thrombocytopenia, autoimmune haemolytic anaemia, skin lesions, arthritis, pulmonary hypertension, heart valve vegetations and spontaneous abortion. LA, ACL and anti-β2GPI were positive in 42 (95%), 28 (64%) and 34 (77%) cases, respectively. Over half (23 cases, 52%) of the patients were triple-positive for antiphospholipid (aPL) antibodies. Among patients with single-positive LA and anti-β2GPI, the proportion with venous thrombosis was 100% (5 cases) and 0% (0 cases), respectively. The arterial thrombosis proportions were 22% (5 cases), 21% (3 cases) and 14% (1 case) in the triple-, double- and single-aPL-positive groups, respectively (P > 0.05). Fifty-three (91%) cases were followed up for 3 to 140 months, with a median time of 32 months. Seven (13%) cases had recurrences or appearances of thrombosis during follow-up, all of which were double- or triple-aPL positive. APS in the paediatric patients is mostly secondary to SLE. ANA positivity and hypocomplementemia are more common in secondary APS, but there are no differences in the other clinical manifestations between the primary and secondary APS groups. Deep vein thrombosis is the most common thrombotic event. Positive LA may increase the risk of venous thrombosis. Multiple-aPL positivity does not increase the proportion of thrombosis. Long-term anticoagulant or antiplatelet therapy is needed to prevent thrombosis recurrence in double- or triple-positive aPL cases.

Abstract
Antiphospholipid antibodies (APLAbs) are generally considered as risk factors for foetal death, for premature birth ≤34weeks due to severe pre-eclampsia or severe placental insufficiency and for recurrent consecutive spontaneous abortions <10weeks. Among these three obstetrical morbidities, only the first one is however not regularly questioned. The coexistence of an inflammatory disease and/or of thrombotic manifestations increases the obstetrical risks. Among the three criteria APLAbs, i.e. lupus anticoagulant (LA), anticardiolipin (aCL) Abs, anti-β2 glycoprotein-I (aβ2GP1)Abs, LA seems the more widely associated to clinical risks, the clinical impact of aβ2GP1Abs is progressively defined and the pejorative impact of triple positivity is still discussed. High quality prospective multicentric epidemiological studies are still awaited. The identification of predictors of pregnancy outcome is necessary to streamline the design and use of new treatments acting on pathophysiological molecular targets.

Abstract
Cognitive disorders have frequently been described in the field of antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE). Nevertheless, the relationship between those disorders and antiphospholipid antibodies (aPL) remains unclear and seems to involve various mechanisms. Overlap with systemic lupus erythematosus, the small sample size of studies, and discrepancies in antiphospholipid antibodies and cognitive impairment determinations complicate analyses of the literature data. In this paper, we summarize current knowledge on epidemiologic, clinical data, imaging findings and treatment of cognitive dysfunction associated with aPL. We separately analyzed data on aPL-positive carriers without history of clinical feature of APS, APS patients without overlaps autoimmune disease, and SLE-associated aPL patients.

Abstract
INTRODUCTION The antiphospholipid syndrome (APS) is an acquired autoimmune disorder predisposing patients to thrombosis or pregnancy complications. Since inverted erythrocyte membranes (iEMs) might provide a physiologically relevant source of anionic phospholipids, we studied the interactions of phospholipid-binding proteins and APS antibodies using iEMs. MATERIALS & METHODS iEMs were prepared from packed erythrocytes by hypotonic lysis. Phosphatidylserine (PS) exposure was confirmed by annexin A5 (A5) binding using fluorescence microscopy and flow cytometry. Binding of β2-glycoprotein I (β2GPI)-IgG immune complexes to iEMs was investigated with gel electrophoresis, western blot and flow cytometry. Functional involvement in coagulation was documented in the thrombin generation assay. RESULTS iEMs readily precipitated purified β2GPI as well as β2GPI from normal plasma and APS plasma. The plasma of APS patients provided higher levels of IgG binding to iEMs relative to healthy controls. Thrombin generation increased with increasing concentrations of iEMs, documenting that coagulation proteins bound to the exposed phospholipids. The LA effect was also distinguished in thrombin generation when comparing APS patients, as indicated by an increased lag time. Agglutination was observed after incubation with APS patient plasma and this was augmented by anti-human globulin. CONCLUSIONS In conclusion, iEMs can provide a more physiological approach than phospholipid vesicle-based tests for investigating APS and are more amenable to standardization than platelet membranes.

Abstract
Contraception is an important issue and should be a matter of concern in every medical visit of adolescent and young patients with chronic rheumatic diseases. This narrative review discusses contraception methods in adolescents with juvenile systemic lupus erythematosus (JSLE), antiphospholipid syndrome (APS), juvenile idiopathic arthritis (JIA) and juvenile dermatomyositis (JDM). Barrier methods are safe and their use should be encouraged for all adolescents with chronic rheumatic diseases. Combined oral contraceptives (COC) are strictly prohibited for JSLE and APS patients with positive antiphospholipid antibodies. Reversible long-acting contraception can be encouraged and offered routinely to the JSLE adolescent patient and other rheumatic diseases. Progestin-only pills are safe in the majority of rheumatic diseases, although the main concern related to its use by adolescents is poor adherence due to menstrual irregularity. Depot medroxyprogesterone acetate injections every three months is a highly effective contraception strategy, although its long-term use is associated with decreased bone mineral density. COC or other combined hormonal contraceptive may be options for JIA and JDM patients. Oral levonorgestrel should be considered as an emergency contraception method for all adolescents with chronic rheumatic diseases, including patients with contraindication to COC.

Abstract
Introduction The long-term risk of first thrombosis and benefit of prophylaxis in antiphospholipid antibody (aPL) carriers without history of thrombosis or obstetrical morbidity is poorly known. This study aimed to evaluate the long-term rate and risk factors associated with a first thrombosis in those patients. Patients and methods After a prior study ended in December 2005 and was already published, we extended the follow-up period of our cohort of aPL carriers. Results Ninety-eight of the 103 patients of the previous study were included. The annual first thrombosis rate was 2.3% per patient-year during a median of 13 years (6-17). None of the baseline characteristics was predictive of risk of first thrombosis, but persistent aPL over time were associated with an increased risk. The stronger association was found in triple aPL-positive carriers: OR 3.38 (95% CI: 1.24-9.22). Of note, conversely to our previous findings, no benefit of aspirin prophylaxis was observed. Conclusion The risk of first thrombosis in aPL carriers without history of thrombosis or obstetrical morbidity was significant, persisted linearly over time and was associated with persistent aPL. This risk was especially increased in triple aPL-positive carriers, in whom a close follow-up seems to be necessary. Nevertheless, the benefit of aspirin prophylaxis remained unclear.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune condition characterized by the presence of antiphospholipid antibodies (aPL) in subjects presenting with thrombosis and/or pregnancy loss. The currently used classification criteria were updated in the international consensus held in Sidney in 2005. Vascular events seem to result of local procoagulative alterations upon triggers influence (the so called “second-hit theory”), while placental thrombosis and complement activation seem to lead to pregnancy morbidity. The laboratory tests suggested by the current classification criteria include lupus anticoagulant, a functional coagulation assay, and anticardiolipin and anti-β2-glycoprotein-I antibodies, generally detected by solid phase enzyme-linked immunosorbent assay. The real challenge for treating physicians is understanding what is the actual weight of aPL in provoking clinical manifestations in each case. As thrombosis has a multi-factorial cause, each patient needs a risk-stratified approach. In this review we discuss the role of thrombotic risk assessment in primary and secondary prevention of venous and arterial thromboembolic disease in patients with APS, focusing on new antibody specificities, available risk scoring models and new coagulation assays.

Abstract
BACKGROUND Antiphospholipid antibodies (aPL) can be detected in asymptomatic carriers and infectious patients. The aim was to investigate whether a novel line immunoassay (LIA) differentiates between antiphospholipid syndrome (APS) and asymptomatic aPL+ carriers or patients with infectious diseases (infectious diseases controls (IDC)). METHODS Sixty-one patients with APS (56 primary, 22/56 with obstetric events only, and 5 secondary), 146 controls including 24 aPL+ asymptomatic carriers and 73 IDC were tested on a novel hydrophobic solid phase coated with cardiolipin (CL), phosphatic acid, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylserine, beta2-glycoprotein I (β2GPI), prothrombin, and annexin V. Samples were also tested by anti-CL and anti-β2GPI ELISAs and for lupus anticoagulant activity. Human monoclonal antibodies (humoAbs) against human β2GPI or PL alone were tested on the same LIA substrates in the absence or presence of human serum, purified human β2GPI or after CL-micelle absorption. RESULTS Comparison of LIA with the aPL-classification assays revealed good agreement for IgG/IgM aß2GPI and aCL. Anti-CL and anti-ß2GPI IgG/IgM reactivity assessed by LIA was significantly higher in patients with APS versus healthy controls and IDCs, as detected by ELISA. IgG binding to CL and ß2GPI in the LIA was significantly lower in aPL+ carriers and Venereal Disease Research Laboratory test (VDRL) + samples than in patients with APS. HumoAb against domain 1 recognized β2GPI bound to the LIA-matrix and in anionic phospholipid (PL) complexes. Absorption with CL micelles abolished the reactivity of a PL-specific humoAb but did not affect the binding of anti-β2GPI humoAbs. CONCLUSIONS The LIA and ELISA have good agreement in detecting aPL in APS, but the LIA differentiates patients with APS from infectious patients and asymptomatic carriers, likely through the exposure of domain 1.

Abstract
INTRODUCTION Obstetric morbidity in women with antiphospholipid antibodies (aPLs) may reflect the adverse effects of aPLs on placental cells such as extravillous trophoblasts and the syncytiotrophoblast. Antiphospholipid antibodies may affect the syncytiotrophoblast after being internalised by members of the Low-density lipoprotein receptor (LDLR) family and the antigen of aPLs, β2 glycoprotein I. AIM This study aimed to determine whether aPL internalization was a mechanism by which aPLs adversely affect extravillous trophoblasts. METHOD of STUDY Fluorescently-labelled monoclonal aPLs IIC5 or ID2 were incubated with first trimester extravillous trophoblast outgrowths and visualized by microscopy. The subcellular expression of β2 glycoprotein I and LDLR family members was investigated by live/permeabilised immunocytochemistry. RESULTS Unlike the syncytiotrophoblast of anchoring villi, monoclonal aPLs were not internalised by extravillous trophoblasts, which expressed LDLR family members intracellularly. The aPL IIC5 bound to the surface of extravillous trophoblasts in a pattern similar to the extracellular expression of β2 glycoprotein I. CONCLUSIONS The mechanisms of action of aPLs are different in extravillous trophoblasts and the syncytiotrophoblast. The interaction of aPLs with the extravillous trophoblast surface, which may involve β2 glycoprotein I, is consistent with reports that aPLs trigger intracellular signaling cascades through cell-surface receptors.

Abstract
This study aims to identify risk factors for thrombosis in patients with systemic lupus erythematosus (SLE) and to validate the efficacy of the partial antiphospholipid (aPL) score for thrombosis prediction and diagnosis of antiphospholipid syndrome (APS). This study included 325 SLE patients, 188 of whom completed a follow-up of 31.01 months (range 23-48 months). Partial aPL score was calculated by adding up the individual scores for activated partial thromboplastin time (APTT), lupus anticoagulant, IgG/IgM anticardiolipin antibodies (aCL), and IgG/IgM anti-β2-glycoprotein I (anti-β2GPI). A simplified aPL score was developed using only APTT, IgG/IgM aCL, and IgG/IgM anti-β2GPI. Partial aPL scores were significantly higher in SLE patients with thrombosis (p < 0.0001). A history of thrombosis (p < 0.0001), a partial aPL score >10 (p < 0.0001), and immunosuppressant use (p = 0.012) were independent risk factors for thrombosis. For patients with a history of thrombosis, partial aPL score was the strongest risk factor for recurrent thrombosis (p < 0.0001, odds ratio = 30.34 (95 % CI 7.70-118.81)). For APS diagnosis, the area under the receiver-operating characteristic curve (AUC) was 0.809 (95 % CI 0.73-0.89) using the partial aPL score. Similarly, the simplified aPL score was significantly associated with thrombosis (p < 0.0001) and was acceptable for APS diagnosis (AUC 0.797, 95 % CI 0.72-0.88). An elevated partial aPL score is a strong risk factor for thrombosis in SLE patients and is a useful tool to predict recurrent thrombosis. Partial aPL score and simplified aPL score, although comprising fewer items than the original aPL score, also represent valuable quantitative indices for APS diagnosis.

Abstract
Autoantibody testing forms an important part of diagnostic workup of patients in Pediatric rheumatology practice. However it is important to understand that the mere presence of autoantibodies does not necessarily mean the presence of an underlying autoimmune disease. Autoantibodies may be present decades before the development of clinical manifestations of an autoimmune disease and may be viewed as harbingers of Autoimmune disease. On the other hand, low-affinity autoantibodies may be present in normal healthy individuals; these natural autoantibodies serve an important function in immune regulation and tolerance. Autoantibody testing in pediatric practice mainly includes testing for anti-nuclear antibodies, anti-dsDNA antibodies, anti-neutrophil cytoplasmic autoantibodies and antiphospholipid antibodies. Rheumatoid factor and anti-CCP do not have much significance in the diagnostic schema in pediatric rheumatology, except perhaps for classification of juvenile idiopathic arthritis (JIA) and prognostication in late-onset polyarticular JIA. The positive predictive value (PPV) of any laboratory test depends on the prevalence of the disease in the population being tested. Hence, test ordering practices greatly impact the performance characteristics and positive predictive value of any laboratory test. A restricted test ordering only in patients with clinical signs and symptoms suggestive of autoimmune disease would thus greatly increase the PPV of tests such as antinuclear antibody used for diagnosing autoimmunity.

Abstract
Patients with malignancy are at higher risk of thrombotic complications due to the hypercoagulability state. Our objective in this study was to assess the serum concentrations of Homocysteine, anti phospholipid antibodies, and anti cardiolipin in patients with benign and malignant breast tumors and study the effect of chemotherapy on the serum levels of these markers. A case control study was carried out on 100 women with malignant breast tumor and 100 age matched control with benign breast tumors.Serum concentrations of heomocystein, anti cardiolipin antibody (IgG and IgMaCL) and anti-phospholipid antibody (IgG and IgMaPL) were measured in all cases. The malignant group was followed for six months, and serum levels of above-mentioned markers were measured again after surgical removal of breast tumor and chemotherapy. Current results showed a significantly higher serum concentration of Homocysteine, IgG and IgMaPL, IgG and IgM aCL in patients with malignant tumor before chemotherapy compared with benign tumor patients. We found a significant decrease in these markers after chemotherapy (P Value<0.05).We propose performing these tests (Homocysteine, IgG and IgM aPL, aCL) in patients with breast malignancy and starting prophylactic anti-thrombotic treatment in those with high serum levels of the markers. In addition, since the serum levels of the markers in patients with malignancy reduce after adjuvant therapies, we strongly recommend using adjuvant chemotherapy in these patients.
