Abstract
BACKGROUND The current recommended therapy of obstetric antiphospholipid syndrome (APS) is a long-term anticoagulant therapy that affects the final event, namely, when the thrombosis has already occurred. Unfortunately, this schedule is not always effective and fails despite the correct risk stratification and an adequate adjusted dose. MATERIALS AND METHODS From 2013 to 2020 we observed 217 women with antiphospholipid antibodies and obstetric morbidities who were treated with conventional treatment protocol (aspirin low doses ± LMWH). Among them 150 (69.1%) successfully completed pregnancy with delivery and live birth on the background of LMWH and aspirin therapy and in 67 (30.9%) women despite a traditional therapy regimen, obstetric complications were noted. Later, 56 of these 67 women became pregnant again and were offered traditional therapy plus hydroxychloroquine. Fifteen women refused HCQ treatment due to possible potential side effects. The final cohort consisted of 41 women with positive antiphospholipid antibodies and obstetric and thrombotic complications who received LMWH, aspirin low doses and HCQ at a dose of 200-400mg per day from the beginning of pregnancy. RESULTS Forty-one aPL women treated with HCQ after failed previous anticoagulant therapy had live births in 32 cases (78%). Adding of HCQ to the combination of LMWH and LDA showed good overall obstetric results and increased the number of live births in another 32 women. So, a total of 182 (83.8%) of initial 217 aPL-women ended their pregnancies with live birth after adding the HCQ to the traditional therapy with LMWH and low doses of aspirin. CONCLUSION In 20-30% of cases the live birth despite anticoagulation cannot be achieved. Perhaps APS is not just anticoagulation. The study of pathophysiological mechanisms suggests that some patients will benefit from other therapy (in addition to anticoagulant). Therapy that affects the early effects of aPL on target cells (monocytes, endothelial cells, etc.) or before binding to receptors-this therapy will be preferable and potentially less harmful than the officially accepted one to date. From this point of view, HCQ looks promising and can be used as an alternative candidate for women with refractory obstetric antiphospholipid syndrome. Adding HCQ should be considered in some selected patients with failed pregnancy after treatment with anticoagulants.

Abstract
Background Antiphospholipid syndrome (APS) is a multisystemic autoimmune disorder characterized by thrombotic events and/or gestational morbidity in patients with antiphospholipid antibodies (aPL). In a previous single center study, APS-related clinical manifestations that were not included in the classification criteria (livedo reticularis, thrombocytopenia, leukopenia) were associated with the presence of circulating immune-complexes (CIC) formed by beta-2-glycoprotein-I (B2GP1) and anti-B2GP1 antibodies (B2-CIC). We have performed a multicenter study on APS features associated with the presence of B2-CIC. Methods A multicenter, cross-sectional and observational study was conducted on 303 patients recruited from six European hospitals who fulfilled APS classification criteria: 165 patients had primary APS and 138 APS associated with other systemic autoimmune diseases (mainly systemic lupus erythematosus, N=112). Prevalence of B2-CIC (IgG/IgM isotypes) and its association with clinical manifestations and biomarkers related to the disease activity were evaluated. Results B2-CIC prevalence in APS patients was 39.3%. B2-CIC-positive patients with thrombotic APS presented a higher incidence of thrombocytopenia (OR: 2.32, p=0.007), heart valve thickening and dysfunction (OR: 9.06, p=0.015) and triple aPL positivity (OR: 1.83, p=0.027), as well as lower levels of C3, C4 and platelets (p-values: <0.001, <0.001 and 0.001) compared to B2-CIC-negative patients. B2-CIC of IgM isotype were significantly more prevalent in gestational than thrombotic APS. Conclusions Patients with thrombotic events and positive for B2-CIC had lower platelet count and complement levels than those who were negative, suggesting a greater degree of platelet activation.

Abstract
OBJECTIVE The aim of this study is to evaluate semaphorin 3A levels in patients with systemic lupus erythematosus (SLE) with and without renal involvement and secondary antiphospholipid antibody syndrome (APS). METHODS Patients with SLE were grouped according to the presence of secondary APS or renal involvement. The control group consisted of age-matched, nonsmoking, healthy volunteers. Semaphorin 3A levels were compared among groups. All patients with SLE were regrouped according to the presence of thrombotic events, miscarriages, and proteinuria, and semaphorin 3A levels were investigated. Finally, semaphorin 3A levels of all patients with SLE as a single group were compared to those of the control patients. RESULTS The mean semaphorin 3A values were 16.16 ± 2.84 ng/mL in the control group, 9.05 ± 5.65 ng/mL in patients with SLE without nephritis and APS, 11.28 ± 5.23 ng/mL in the SLE with APS group, and 8.53 ± 5.11 ng/mL in the lupus nephritis group. When all 3 patient groups were examined as a single group, the mean semaphorin 3A value was significantly lower than that of the control group. Semaphorin 3A was reduced in patients with SLE with thromboembolism and/or history of miscarriage. CONCLUSION Semaphorin 3A levels were lower in all patient groups compared to the control group. Moreover, the reduced semaphorin 3A levels in patients with a history of thromboembolism and/or miscarriage suggest that semaphorin 3A may play an important role in the pathogenesis of vasculopathy.

Abstract
Antiphospholipid syndrome (APS) is an acquired thrombotic autoimmune disorder that is clinically characterized by the development of thrombosis and obstetric morbidities in patients with antiphospholipid antibodies. Due to hypercoagulability, the focus of management is anticoagulation for the prevention of thrombosis and its recurrence. When such patients undergo surgery, however, the underlying risk of thrombosis increases as a result of anticoagulant withdrawal, immobilization, and/or intimal injury. Conversely, there is also an increased risk of bleeding due to thrombocytopaenia, possible disseminated intravascular coagulation, or progression to catastrophic APS, as a result of excessive anticoagulation, surgery, and infection. Measures for appropriate perioperative anticoagulation are discussed in this review, as well as anaesthetic considerations for preventing perioperative complications in patients with APS undergoing non-cardiac surgery.

Abstract
Neuropsychiatic systematic lupus erythematosus (NPSLE) is a form of SLE involves the inflammation and/or thrombotic event in the nervous system. Patients with NPSLE are likely to have a positive antiphospholipid antibody (aPL), therefore are at higher risk of recurrent ischemic stroke. The management of NPSLE with aPLrelated stroke is rather different from the traditional ischemic stroke. One must treat it with anticoagulation and immunosuppressive therapy. The present case is a 47-yearold Taiwanese female with NPSLE and positive aPL, presented with a recurrent MCA ischemic stroke. Initial laboratory results showed significantly elevated levels of anti-ANA, anti-dsDNA, anti-cardiolipin, and decreased complement levels. Due to multiple contraindications for tPA, she was treated with antiplatelet, anticoagulation, steroid pulse therapy, and plasmapheresis during the hospitalization. Despite treatments, her stroke progressed to multi-focal lesions, involving the ACA, MCA, and basal ganglion. On follow up of her brain CT scan showed tissue edema and suspicious for subfalcine herniation. Responding to this clinical deterioration, we stopped warfarin and started mannitol. Eventually, her condition improved and was transferred to the rehabilitation program. Currently, there is no unified guideline regarding the secondary prevention of ischemic stroke in NPSLE with aPL patients. Additionally, previously reported use of steroid pulse therapy and plasmapheresis can potentially harm the patient. Clinicians must be cautious when treating such patient.

Abstract
PURPOSE OF REVIEW Diffuse alveolar hemorrhage (DAH) is a rare but devastating manifestation of antiphospholipid syndrome (APS) patients with or without other systemic autoimmune diseases. Data regarding diagnosis and treatment are limited to case series. We review diagnostic and therapeutic strategies employed in APS patients with DAH and discuss our experience in managing these complex patients. RECENT FINDINGS Pulmonary capillaritis likely contributes to the pathogenesis, however is only observed in half of the biopsies. Corticosteroids induce remission in the majority of patients, however almost half recur and require a steroid-sparing immunosuppressive to maintain remission. Cyclophosphamide- or rituximab-based regimens achieve the highest remission rates (50%); other strategies include intravenous immunoglobulin, plasmapheresis, mycophenolate mofetil, and/or azathioprine. Given the rarity of DAH in APS, treatment is guided by interdisciplinary experience. Why certain patients achieve full remission with corticosteroids while others require immunosuppressive agents is unknown; future research should focus on the pathophysiology and optimal management.

Abstract
Antiphospholipid syndrome is an autoimmune disease characterized by vascular thrombosis involving both the arterial and venous systems that can lead to tissue ischemia or end-organ damage. Much of the literature describes various symptoms at initial presentation, but isolated tissue ischemia manifesting as a solitary blue toe is unusual. We discuss a case of a 23-year-old man who presented to the emergency department with a solitary blue fourth digit with minimal erythema and edema, who was suffering from exquisite pain. Following an extensive workup, the patient was diagnosed with antiphospholipid syndrome with thrombi of the vasculature in their lower extremity. With therapeutic anticoagulation, the patient's symptoms subsided and amputation of the digit was prevented.

Abstract
Autoimmune rheumatic diseases are characterised by an abnormal immune system response, complement activation, cytokines dysregulation and inflammation. In last years, despite many progresses in managing these patients, it has been shown that clinical remission is reached in less than 50% of patients and a personalised and tailored therapeutic approach is still lacking resulting in a significant gap between guidelines and real-world practice. In this context, the need for biomarkers facilitating early diagnosis and profiling those individuals at the highest risk for a poor outcome has become of crucial interest. A biomarker generally refers to a measured characteristic which may be used as an indicator of some biological state or condition. Three different types of medical biomarkers has been suggested: i. mechanistic markers; ii. clinical disease markers; iii. therapeutic markers. A combination of biomarkers from these different groups could be used for an ideal more accurate diagnosis and treatment. However, although a growing body of evidence is focused on improving biomarkers, a significant amount of this information is not integrated on standard clinical care. The overarching aim of this work was to clarify the meaning of specific biomarkers during autoimmune diseases; their possible role in confirming diagnosis, predicting outcome and suggesting specific treatments.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune antibody-mediated condition characterized by thrombotic events and/or pregnancy morbidity in association with persistent positivity to antiphospholipid antibodies (aPL). The nervous system is frequently affected, as intracranial vessels are the most frequent site of arterial pathology. Over the course of years, many other neurological conditions not included in the diagnostic criteria, have been associated with APS. The pathogenic mechanisms behind the syndrome are complex and not fully elucidated. aPL enhance thrombosis, interfering with different pathways. Nevertheless, ischemic injury is not always sufficient to explain clinical features of the syndrome and immune-mediated damage has been advocated. This may be particularly relevant in the context of neurological complications. The reason why only a subgroup of patients develop non-criteria nervous system disorders and what determines the clinical phenotype are questions that remain open. The double nature, thrombotic and immunologic, of APS is also reflected by therapeutic strategies. In this review we summarize known neurological manifestations of APS, revisiting pathogenesis and current treatment options.

Abstract
Clinical studies have reported different diagnostic/predictive values of antibodies to domain 1 or 4/5 of β2glycoproteinI in terms of risk of thrombosis and pregnancy complications in patients with antiphospholipid syndrome. To obtain direct evidence for the pathogenic role of anti-domain 1 or anti-domain 4/5 antibodies, we analyzed the in vivo pro-coagulant effect of two groups of 5 sera IgG each reacting selectively with domain 1 or domain 5 in lipopolysaccharide (LPS)-treated rats. Antibody-induced thrombus formation in mesenteric vessels was followed by intravital microscopy, and vascular deposition of β2glycoproteinI, human IgG and C3 was analyzed by immunofluorescence. Five serum IgG with undetectable anti-β2glycoproteinI antibodies served as controls. All the anti-domain 1-positive IgG exhibited potent pro-coagulant activity while the anti-domain 5-positive and the negative control IgG failed to promote blood clot and vessel occlusion. A stronger granular deposit of IgG/C3 was found on the mesenteric endothelium of rats treated with anti-domain 1 antibodies, as opposed to a mild linear IgG staining and absence of C3 observed in rats receiving anti-domain 5 antibodies. Purified anti-domain 5 IgG, unlike anti-domain 1 IgG, did not recognize cardiolipin-bound β2glycoproteinI while being able to interact with fluid-phase β2glycoproteinI. These findings may explain the failure of anti-domain 5 antibodies to exhibit a thrombogenic effect in vivo, and the interaction of these antibodies with circulating β2glycoproteinI suggests their potential competitive role with the pro-coagulant activity of anti-domain 1 antibodies. These data aim at better defining “really at risk” patients for more appropriate treatments to avoid recurrences and disability.

Abstract
OBJECTIVE Idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome is a rare entity with a potentially poor visual prognosis. Our objective is to review the clinical presentation and long-term outcomes of patients with IRVAN syndrome. DESIGN This is a retrospective case series. METHODS We reviewed the charts of all the patients diagnosed with IRVAN syndrome at our tertiary care centre from 2002 to 2015. RESULTS We included the long-term clinical outcomes of 7 eyes (5 patients) diagnosed with IRVAN syndrome. After a mean follow-up of 84.9 months, best-corrected visual acuity was 20/40 or better in the majority of eyes (70%). Four (57.1%) patients had systemic conditions, namely, multiple sclerosis, ischemic stroke, and positive antiphospholipid titres. All eyes were treated with laser photocoagulation. Four (40%) eyes received adjunctive intravitreal bevacizumab injections. CONCLUSION IRVAN is an important diagnosis for clinicians to recognize. When treated in a timely manner, long-term visual outcomes can be favourable.

Abstract
: A case report of a patient with antiphospholipid syndrome (APS) with positive lupus anticoagulant and a mechanical mitral valve replacement (MVR) who presented with a thrombosis and difficult-to-control INRs. Current literature on anticoagulation options for patients who present with these conditions as well as alternate laboratory assays are reviewed. APS can present a unique complexity and challenge to appropriate anticoagulation on warfarin. Although there are emerging data regarding the use of novel oral anticoagulants to treat this condition, they do not justify their use in a patient with APS and an MVR because of a current lack of evidence. CFX testing may be used to calibrate INRs when there is a concern for false readings because of lupus anticoagulant interaction with INR assays.

Abstract
Antiphospholipid syndrome (APS) is an acquired autoimmune disease characterized by thromboembolic events, pregnancy morbidity, and the presence of antiphospholipid (aPL) antibodies. There is sound evidence that aPL act as pathogenic autoantibodies being responsible for vascular clots and miscarriages. However, the exact mechanisms involved in the clinical manifestations of the syndrome are still a matter of investigation. In particular, while vascular thrombosis is apparently not associated with inflammation, the pathogenesis of miscarriages can be explained only in part by the aPL-mediated hypercoagulable state and additional non-thrombotic effects, including placental inflammation, have been described. Despite this difference, evidence obtained from animal models and studies in APS patients support the conclusion that complement activation is a common denominator in both vascular and obstetric APS. Tissue-bound aPL rather than circulating aPL-beta2 glycoprotein I immune complexes seem to be responsible for the activation of the classical and the alternative complement pathways. The critical role of complement is supported by the finding that complement-deficient animals are protected from the pathogenic effect of passively infused aPL and similar results have been obtained blocking complement activation. Moreover, elevated levels of complement activation products in the absence of abnormalities in regulatory molecules have been found in the plasma of APS patients, strongly suggesting that the activation of complement cascade is the result of aPL binding to the target antigen rather than of a defective regulation. Placental complement deposits represent a further marker of complement activation both in animals and in patients, and there is also some suggestive evidence that complement activation products are deposited in the affected vessels. The aim of this review is to analyze the state of the art of complement involvement in the pathogenesis of APS in order to provide insights into the role of this system as predictive biomarker for the clinical manifestations and as therapeutic target.

Abstract
Antiphospholipid syndrome (APS) is a systemic autoimmune disorder marked by thrombosis and/or pregnancy morbidity in the presence of antiphospholipid antibodies (aPL). At the present time, treatment is primarily focused on anticoagulation. However, there is increasing awareness of the mechanisms involved in APS pathogenesis, which has led to the trial of novel therapies targeting those mechanisms. Following a brief review of the etiopathogenesis of and current management strategies in APS, this paper focuses on the evidence for these potential, targeted APS treatments, e.g., hydroxychloroquine, statins, rituximab, belimumab, eculizumab, defibrotide, sirolimus, and peptide therapy.

Abstract
Anti-phospholipid syndrome (APS) is an acquired pro-thrombotic autoimmune disease that predisposes to thrombotic events and/or obstetric complications, in the persistent presence of anti-phospholipid antibodies (aPL). Life long moderate-intensity anticoagulation is the option of choice for aPL-positive patients with a previous thrombosis; critical issues concern the management of those with a history of arterial event due to the high rate of recurrence. Alternatives comprise anti-platelet agents and high-intensity anticoagulation. Low dose aspirin (LDASA) and low molecular weight heparin provide the mainstay of the treatment of obstetric APS, allowing a birth rate in 70% of cases. The management of refractory APS, thrombotic as well as obstetric, is highly debated, but an increasing burden of evidence points towards the beneficial effects of multiple treatments. Similarly, a management envisaging multiple drugs (anticoagulation, steroids, plasma exchange and/or intravenous immunoglobulins) is the most effective approach in catastrophic APS. Asymptomatic aPL carriers are at higher risk of thrombotic and obstetric complications compared to the general population, thus potentially benefitting of a pharmacological intervention. LDASA and hydroxychloroquine can be considered as options, in particular in case of high risk aPL profile, concomitant cardiovascular risk factors or associated autoimmune disease. APS is apparently a simple condition, but its multifaceted nature requires a complex and tailored treatment.

Abstract
BACKGROUND The antiphospholipid syndrome (APS) is defined by simultaneous presence of vascular clinical events and antiphospholipid antibodies (aPL). The aPL considered as diagnostics are lupus anticoagulant and antibodies anticardiolipin (aCL) and anti-ß2 glycoprotein-I (aB2GP1). During recent years, IgA aB2GP1 antibodies have been associated with thrombotic events both in patients positive, and mainly negative for other aPL, however its value as a pro-thrombotic risk-factor in asymptomatic patients has not been well defined. OBJECTIVE To test the role of IgA anti B2GP1 as a risk factor for the development of APS-events (thrombosis or pregnancy morbidity) in asymptomatic population with a 5-year follow-up. METHODS 244 patients isolated positive for anti-beta2-glycoprotein I IgA (Group-1 study) and 221 negative patients (Group-2 control) were studied. All the patients were negative for IgG and IgM aCL. RESULTS During the follow-up, 45 patients (9.7%) had APS-events, 38 positive for IgA-aB2GP1 and 7 negative (15.6% vs 3.2%, p<0.001). The incidence rate of APS-events was 3.1% per year in IgA-aB2GP1 positive patients and 0.6% per year in the control group. Arterial thrombosis were the most frequent APS-events (N = 25, 55%) and were mainly observed in Group-1 patients (21 vs 4, p = 0.001). Multivariate analysis were shown as independent risk-factors for the development of APS-events, age, sex (men) and presence of IgA-aB2GP1 (odds ratio 5.25, 95% CI 2.24 to 12.32). CONCLUSION The presence of IgA-aB2GP1 in people with no history of APS-events is the main independent risk factor for the development of these types of events, mainly arterial thrombosis.

Abstract
INTRODUCTION Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by vascular thrombosis and/or pregnancy morbidity associated with the persistent presence of antiphospholipid antibodies (aPL) including lupus anticoagulant (LA), anticardiolipin antibodies (aCL), and anti-β2 glycoprotein I antibodies (aβ2GPI). AREAS COVERED APS is considered as the most common acquired hypercoagulation state of autoimmune origin in children. Unfortunately, data about incidence, prevalence, thrombosis risk and effective treatment in paediatric APS are limited and unmethodical. Expert commentary: This review summarizes recent clinical, laboratory and therapy characterization of paediatric APS and emphasizes the differences between paediatric and adult populations.

Abstract
Pregnancy morbidity is part of the clinical spectrum of the anti-phospholipid syndrome (APS), with an important social and economical cost. Antiplatelet and anticoagulant agents are effective in preventing the clinical manifestations in the majority of the patients. However, a consistent proportion of the pregnant women present recurrences in spite of the standard therapy. Observational studies and anecdotal reports raised the issue of additional therapeutic strategies in these refractory cases. Among these, anti-malarials (AMs) and in particular hydroxychloroquine (HCQ) are becoming more and more popular in APS as well as in other systemic autoimmune rheumatic conditions. AMs display a pleiotropic activity spanning from immunomodulation effect to anti-inflammatory and anti-thrombotic activities, all of which potentially useful in APS. The well-known safety of HCQ in pregnancy encouraged its use in pregnant women with autoimmune rheumatic disorders including APS and observational reports suggested a protective effect on obstetrical recurrences. Since thrombosis does not seem to be the main pathogenic mechanism in obstetric APS, effectiveness of the treatment with HCQ should be related to other pharmacological effects rather than to the anti-platelet or anti-thrombotic activity of the molecule. Experimental models showed that HCQ may restore some defective biological functions induced by anti-phospholipid antibodies (aPL) on trophoblasts and a recent study reported a protective effect on in vivo aPL-mediated placental and foetal neurodevelopmental abnormalities. Although the rational behind the use of HCQ in obstetric APS is sound, the evidence from the real life is not conclusive and a critical appraisal through clinical trials is mandatory.

Abstract
Subacute-acute, hyperacute, or even catastrophic and fulminant respiratory events occur in almost all classic connective tissue disorders (CTDs); they may share systemic life-threatening manifestations, may precipitously lead to respiratory failure requiring ventilatory support as well as a combination of specific therapeutic measures, and in most affected patients constitute the devastating end-of-life event. In CTDs, acute respiratory events may be related to any respiratory compartment including the airways, lung parenchyma, alveolar capillaries, lung vessels, pleura, and ventilatory muscles. Acute respiratory events may also precipitate disease-specific extrapulmonary organ involvement such as aspiration pneumonia and lead to digestive tract involvement and heart-related respiratory events. Finally, antirheumatic drug-related acute respiratory toxicity as well as lung infections related to the rheumatic disease and/or to immunosuppression complete the spectrum of acute respiratory events. Overall, in CTDs the lungs significantly contribute to morbidity and mortality, since they constitute a common site of disease involvement; a major site of infections related to the 'mater' disease; a major site of drug-related toxicity, and a common site of treatment-related infectious complications. The extreme spectrum of the abovementioned events, as well as the 'vicious' coexistence of most of the aforementioned manifestations, requires skills, specific diagnostic and therapeutic means, and most of all a multidisciplinary approach of adequately prepared and expert scientists. Avoiding lung disease might represent a major concern for future advancements in the treatment of autoimmune disorders.
