Abstract
In antiphospholipid syndrome (APS), the risk of clinical manifestations increases with higher titers of antiphospholipid antibodies (aPL). Despite the adoption of aPL titers in the classification approach to aPL-positive subjects, the value of longitudinal monitoring of those titers in the follow-up is still debated, being well studied only in systemic lupus erythematosus (SLE). The literature suggests that the rate of aPL positivity decreases during follow-up in primary APS, estimating that seroconversion occurs in between 8.9 and 59% of patients over time. Negativisation of aPL occurs more frequently in asymptomatic aPL carriers than in patients with full-blown APS as well as in subjects with single aPL positivity or low aPL antibody titers. In patients with SLE, aPL typically behave fluctuating from positive to negative and back again in the course of follow-up. The few studies assessing the longitudinal course of aPL positivity with no associated systemic connective tissue disease reported a progressive decrement of aPL titers over time, in particular of antibodies against β2 glycoprotein I (antiβ2GPI) and cardiolipin (aCL) of IgG isotype. After a thrombotic event, aPL titers tend to decrease, as emerged from cohorts of both primary and secondary APS. Hydroxychloroquine has been identified as the most effective pharmacological agent to reduce aPL titers, with multiple studies demonstrating a parallel reduction in thrombosis rate. This review addresses available evidence on the significance of aPL titer fluctuation from clinical, therapeutic and pathogenic perspectives.

Abstract
Long-term vitamin K antagonist (VKA) anticoagulation is the cornerstone of the management of subjects with thrombotic antiphospholipid syndrome (APS). Recent investigations have opened up new discussion points regarding the potential for stopping anticoagulant medication in patients with a history of thrombotic APS who no longer have detectable aPL (the so called aPL negativization). Despite the lack of unanimous agreement, some experts agreed on defining aPL negativization as the presence of two negative determinations, 1 year apart. What to do in order to optimize the management of these subjects with thrombotic APS when aPL turn negative is still a matter of debate. In this review, we aim to summarize the main evidence highlighting the magnitude of aPL negativizing among patients with APS and the features to keep in mind when considering (or not) stopping anticoagulation.

Abstract
Objectives This study aimed to investigate whether there are sex differences in clinical characteristics and prognosis in patients with primary thrombotic antiphospholipid syndrome (ptAPS). Methods From January 2013 to July 2021, 154 consecutive patients diagnosed with ptAPS were prospectively recruited. Multivariable Cox regression was used to evaluate the association between gender and the composite endpoint including thromboembolic recurrence or all-cause death during follow-up. Results Totally, 80 (52%) male and 74 (48%) female patients with ptAPS were included, and men had a higher percentage of smokers/ex-smokers [50 (62%) vs. 6 (8%), p < 0.001] and hyperhomocysteinemia [26 (32%) vs. 9 (12%), p = 0.003]. The baseline thromboembolic events were similar in two genders, except for limb ischemia [15 (19%) in men vs. 1 (1%) in women, p < 0.001]. During a median follow-up of 42 months, the composite endpoint occurred in 30 (38%) male and 15 (20%) female patients (p = 0.019). Male gender [HR 2.499, 95% CI (1.316, 4.743), p = 0.005] and warfarin administration [HR 0.482, 95% CI (0.257, 0.905), p = 0.023] remained independent risk factors for the composite endpoint. Male gender [HR 3.699, 95% CI (1.699, 8.246), p = 0.001] and isolated lupus anticoagulant positivity [HR 2.236, 95% CI (1.039, 4.811), p = 0.040] were independent risk factors for thromboembolic recurrence. Conclusion There are sex disparities in the clinical characteristics in patients with ptAPS and the male gender is an independent risk factor for the poor prognosis. Male patients with isolated lupus anticoagulant (LA) positivity have the highest risk of thromboembolic recurrence.

Abstract
The rate of antiphospholipid antibodies (aPL) negativization in antiphospholipid syndrome (APS) patients is uncertain, but it is estimated to be as high as 8%. Currently, a consensus definition of aPL negativization is lacking, as well as international recommendations on how to approach treatment in patients with a persistent aPL negative seroconversion. Evaluate the clinical approach and level of consensus among experts from the APS Study Group of the Italian Society for Rheumatology (SIR-APS) in different clinical scenario. Experts of SIR-APS were contacted using a survey methodology. A structured survey was circulated among 30 experts.Up to 90% of the interviewed experts agreed on defining aPL negativization as the presence of two negative determinations, one year apart (90%).Almost full consensus exist among experts in some clinical settings, including: a) the role of aPL negativization in the management of a thrombotic event determined by concomitant presence of cardiovascular risk factors, both modifiable and not modifiable (90%); b) approach to young patients with triple aPL positivity who experienced pulmonary arterial thrombotic event and tested negative for aPL detection after five year of vitamin K antagonist (VKA) treatment (90%); c)the use of "extra criteria" aPL antibodies testing before pondering VKA suspension (93%). A substantial agreement exists among expert on how to define aPL negativization. VKA suspension should be embraced with extreme caution, particularly in case of previous thrombotic events and/or triple aPL positivity. Nevertheless, VKA cessation might be considered when risk factors are carefully monitored/treated and the presence for "extra criteria" is ruled out.

Abstract
BACKGROUND/PURPOSE Pediatric antiphospholipid syndrome (APS) is a thromboinflammatory disease characterized by the presence of circulating antiphospholipid antibodies and either thrombotic events or pregnancy morbidity. The objective of this study was to review a large institution's experience to better understand the characteristics of children with APS. METHODS We conducted a retrospective review of pediatric APS at a tertiary referral center. The electronic medical record system was queried from 2000 through 2019, and 21 cases were included based on meeting the revised Sapporo Classification criteria by age 18 or younger. Comparisons between primary and secondary APS patients were made with two-tailed t-tests. RESULTS Twenty-one patients were included with a median age at diagnosis of 16 years and median follow-up of 5.8 years. Secondary APS was slightly more common than primary APS (11 vs. 10 cases) and was primarily diagnosed in the context of systemic lupus erythematosus. Two thirds of patients (67%) also had "non-criteria" manifestations of APS including thrombocytopenia, autoimmune hemolytic anemia, and livedo reticularis/racemosa. Almost half of patients (43%) had recurrent thrombosis, typically when patients were subtherapeutic or non-adherent with anticoagulation. Damage Index in Patients with Thrombotic APS (DIAPS) scores indicated a chronic burden of disease in both primary and secondary APS patients. CONCLUSION This case series of pediatric APS provides important context regarding disease phenotypes displayed by children with APS. High prevalence of non-criteria clinical manifestations highlights the need to consider these characteristics when developing pediatric-specific classification criteria and when considering this relatively rare diagnosis in pediatric practice.

Abstract
Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by arterial and venous thrombotic manifestations and/or pregnancy-related complications in patients with persistent antiphospholipid (aPL) antibodies. The introduction of Sapporo's classification criteria allowed uniformity in the classification of this pathology, representing a considerable advance in its diagnosis. However, currently some doubts about the application of these criteria still persist. The aim of this study was to contribute to the better understanding of APS by the assessment of aPL prevalence, the association between clinical and laboratory tests, and evaluation of the aPL confirmatory profile. In this study, 1,179 samples from patients with suspected APS of both genders, without age restrictions, who were advised to test for complete aPL's profile were analyzed. The samples were tested for lupus anticoagulant (LAC), anticardiolipin immunoglobulin (Ig) G/IgM and anti-β-2-glycoprotein I IgG/IgM antibodies. Patient samples with isolated test requests for analysis and samples from patients under the influence of anticoagulants or in an infectious process were excluded. The overall positivity found was 17.9% and the most frequent aPL was LAC. The antibodies were determined in isolation and in association. The prevalence of triple positivity was 0.8% and double positivity was 1.8%. Positivity was higher in inpatient/emergency services compared with outpatient services. There was a higher positivity in individuals over 41 years, males, patients with systemic lupus erythematosus, kidney complications, and deep vein thrombosis/thrombophlebitis. The positivity confirmation with second sample was 39.5% and the confirmation profile shows that 50.6% of samples confirmed with same positivity profile; 17.3% with a different profile and regarding to these, 2.5% of the samples confirmed positivity with a different antibody from the previously detected. This study suggests that the aPL's positivity tends to increase with age, showing that the aPL's testing should be avoided during an acute event and reinforces the need for complete aPL laboratory profile in the second sample and subsequent determinations.

Abstract
Introduction: Some patients with positive antiphospholipid antibodies (aPL) have not been included in randomized clinical trials or observational registries and, therefore, information on their risk of obstetric or thrombotic recurrence and optimal treatment is scarce.Areas covered: In the present review, the existing evidence regarding the management of two laboratory scenarios not covered by the guidelines is presented: (1) patients with antiphospholipid syndrome (APS) clinical manifestations and aPL positivity not fulfilling APS laboratory criteria, and (2) the possibility of discontinuing anticoagulation in APS patients whose aPL become persistently negative.Expert opinion: Growing evidence suggests a role for low titers and 'non-criteria' aPL, especially in obstetric APS. Treatment is not formally recommended but might be considered according to the individual's risk profile. Regarding the question of whether or not to discontinue anticoagulants after the 'spontaneous' disappearance of aPL, there is no definite answer. Retrospective studies seem to suggest that withdrawal of anticoagulation could be safe in certain patients with APS, especially in those with a first provoked venous thrombosis and whose aPL became persistently negative during follow-up. Still, before the withdrawal can be recommended in routine clinical practice, multicenter and prospective studies are required to validate this hypothesis.

Abstract
PURPOSE OF REVIEW Antiphospholipid syndrome (APS), more common than once believed, is an autoimmune disease best known for its high risk of incident and recurrent thrombotic events. The approach to treatment potentially differs from treatment of thrombosis in the general population, and this article endeavors to review the latest updates on this topic. RECENT FINDINGS The epidemiology of APS is being increasingly elucidated by large population-based studies, with APS perhaps affecting as many as 1 in 2000 individuals. Vitamin K antagonists, aspirin, and heparinoids continue to have obvious roles in the management of patients with APS. There has recently been intensive study of direct oral anticoagulants in APS, with the most recent randomized studies raising concerns about their inferiority to vitamin K antagonists, at least in some subgroups. Other approaches to treating APS beyond anticoagulants and antiaggregants are also receiving increased attention in mechanistic and preclinical studies with an eye toward future roles in patients with refractory and/or microvascular disease. Pediatric APS is identified as an area in desperate need of additional prospective research. SUMMARY Progress continues to be made in pursuit of improving the lives of individuals afflicted with APS. The most important future directions would seem to involve leveraging modern molecular technologies in order to improve subphenotyping of antiphospholipid antibody-positive individuals. This will help personalize risk profiles and ideally define the optimal approach to therapy based on future risk, rather than past morbid events.

The antiphospholipid syndrome may induce non-thrombotic internal jugular vein stenosis: two cases report. BMC Neurol 2021; 21:9.

Abstract
BACKGROUND Antiphospholipid syndrome (APS) is associated with a high incidence of thrombotic events, either arterial thrombosis or venous thrombosis. However, APS-related non-thrombotic venous stenosis is rarely reported. CASE PRESENTATION This study described two cases of young women with APS-related internal jugular vein stenosis (IJVS) and reviewed current literature on this issue, including clinical features, diagnosis, and treatment. CONCLUSIONS IJVS is a rather rare complication of APS. Two cases were reported for the first time that high titer of antiphospholipid antibodies (aPL) might mediate direct vessel wall damage and further induce venous stenosis despite long-term standardized anticoagulation to prevent thrombus formation. Therefore, dynamic monitoring of autoantibodies and concomitant use of anticoagulants and corticosteroids may be necessary to the management of APS and its complications.

Abstract
PURPOSE To evaluate the prevalence of a spectrum of autoantibodies in adult patients with non-infectious uveitis compared to healthy controls. METHODS This is a case-control study conducted in a tertiary referral center. Serum positivity to auto-antibodies directed at membranous phospholipids (aPL), nuclear antigens, and cytoplasmic (ANCA) antigens were assessed in sera from 63 non-infectious uveitis patients, and 78 healthy controls. Uveitis patients' demographic and clinical data were collected retrospectively from their medical charts. RESULTS Of the spectrum of antibodies evaluated only aPL were linked with uveitis (OR 11.2, CI 1.4-92.1), as 13 (20.6%) uveitis patients were positive to at least one of the screened aPL, namely either anti-cardiolipin (aCL), anti-β2-glycoprotein (aβ2GPI), or anti-phosphatidylserine/prothrombin (aPS/PT). aCL antibodies were detected in 5/63 (7.9%) of uveitis patients and in none of controls (p = 0.016). Positivity to either aCL or aβ2GPI was noted in 8/63 (12.7%) of uveitis patients and in 1 (1.3%) of the controls (p = 0.011). Of the 13 uveitis patients positive to any of the aPL antibodies, 8 (62%) had exclusively anterior uveitis, 9 (69%) were idiopathic, and none had evidence of posterior vaso-occlusive involvement or systemic thrombotic manifestations. CONCLUSION An association between aPL and uveitis among an unselected population of patients with no evidence of thrombosis or presence of the antiphospholipid syndrome was documented in this study. This link was observed, alike the general population of uveitis patients, mainly in patients with anterior eye inflammation. A possible interaction between aPL and uveitis, mediated by non-thrombotic mechanisms, requires further studies.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize the diagnosis and management of the antiphospholipid syndrome (APS) in children. RECENT FINDINGS APS is a rare, acquired autoimmune systemic disease that can result in significant morbidity in children related to vascular thrombosis. The diagnosis and management of APS in children can be challenging due to a lack of validated diagnostic criteria and the rarity of the disease. In addition, many healthy children have transient circulating antiphospholipid antibodies without thrombotic complications. Nevertheless, epidemiological studies suggest that APS represents a greater relative proportion of thrombotic disease in children than it does in adults. Management of pediatric APS is largely inferred from adult data despite unique characteristics of pediatric APS. The current recommendations include long-term anticoagulation, which can be problematic in young, active individuals. There is little data on potential benefits of nonantithrombotic therapy in the management of pediatric APS. SUMMARY Data on pediatric APS are limited, but evidence suggests that using current available diagnostic testing is valuable and, until further evidence is available, treating thrombotic complications with heparins or warfarin should be standard of care.

Abstract
Abstract
Objective
The withdrawal of oral anticoagulation (OAC) in patients with SLE and secondary aPL syndrome (SAPS) who become seronegative has not been clearly investigated to date. Our aim was to evaluate the prevalence of aPL seroconversion and the prognosis of SLE patients with SAPS who withdrew OAC after aPL negativization.
Methods
We retrospectively analysed data of all SLE patients (ACR criteria) with SAPS (Sydney criteria) prospectively followed-up in our clinic. aPL seroconversion was defined as negativization of lupus anticoagulant, aCL, and anti-β2glycoprotein-1 antibodies on two or more consecutive measurements, at least 12 weeks apart. OAC discontinuation was defined as the definitive withdrawal of all anticoagulants.
Results
Fifty-five out of 513 (10.7%) SLE patients had vascular SAPS. Sixteen patients (29.1%) became aPL seronegative during follow-up. Immunosuppressive therapy predicted aPL negativization (odds ratio 5.211, 95%CI 1.341, 20.243), whereas APS diagnosis prior to that of SLE (odds ratio 0.078, 95%CI 0.008, 0.799) and triple-positive profile (odds ratio 0.264, 95%CI 0.115, 0.609) were negative predictors of aPL negativization. OAC was discontinued in 13/55 patients (23.6%), after a median follow-up of 45 months (range 1–276) from aPL seroconversion. SLE-related modifiable risk factors for thrombosis were observed in 10/13 patients (77%) at the time of the thrombotic event. No thrombotic recurrences were observed during a mean follow-up time of 44 (19) months from OAC discontinuation.
Conclusions
Our results suggest that OAC can be safely discontinued in SLE patients who became persistently seronegative for aPL, at least when aPL-related thrombotic events occurred in presence of other thrombotic risk factors.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune disease that demonstrates antiphospholipid antibodies that cause hypercoagulability and leads to venous and arterial thrombosis. Autoantibodies to a disintegrin-like and metalloprotease with thrombospondin type I motif, member 13 (ADAMTS 13) play a role in the microthrombosis of thrombotic thrombocytopenic purpura in APS patients.

Abstract
PURPOSE OF REVIEW The antiphospholipid syndrome (APS) is characterized by the development of thrombotic events and pregnancy morbidity in the presence of antiphospholipid antibodies (aPL). An infectious etiology for this syndrome has been postulated. The present review is aimed to summarize recent evidence about the role of infections and vaccines in the pathogenesis of the APS (including its catastrophic variant). RECENT FINDINGS There is an increased risk of developing aPL in various infections, particularly in viral infections. The most frequent infection related to aPL has been hepatitis C virus. These antibodies may be associated with thromboembolic events, including catastrophic APS. There is a link between vaccinations, such as the tetanus toxoid and aPL, due to molecular mimicry between the two molecules. Accumulated evidence supports that the presence of aPL is associated with a variety of infections, including viruses, bacteria, fungi, and parasites, and the main mechanism to explain this correlation is molecular mimicry. Moreover, a link between vaccinations, such as the tetanus toxoid, and APS has also been described.

Abstract
Inherited and acquired thrombophilias and hypercoagulable states, such as active cancer, estrogen-induced, autoimmune disorders, major surgery, hospitalization, and trauma, are well-known risk factors for venous thromboembolism (VTE). The effect of these on recurrent VTE is different for each specific risk factor. The major risk factors affecting VTE recurrence include the presence of active cancer and an unprovoked first VTE. In addition, the use of combined female hormones in a woman with a previous history of estrogen-related VTE is a major risk factor for VTE recurrence. The extent of influence of inherited thrombophilia on the risk of recurrence is controversial. Conversely, the presence of antiphospholipid antibodies, specifically triple positive carriers, appears to increase the risk of VTE recurrence. Understanding the rates of recurrent VTE in a patient and the individual risk of bleeding is important in determining the duration of anticoagulation therapy.

Abstract
PURPOSE OF REVIEW The aim of this review is to provide an update of the therapeutic tools for thrombotic anti-phospholipid syndrome (APS), focusing on the last 5 years. RECENT FINDINGS Early studies appointed anticoagulation at moderate intensity as the mainstay of treatment of thrombotic APS; in the last 5 years, the strategy has not much mutated. Some uncertainties regarding the role of direct oral anticoagulants and the optimal regimen for arterial thrombotic APS still persist: high-intensity anticoagulation, anticoagulation plus anti-platelet agent, and double anti-platelet agents being the possible alternatives. Several drugs have been proposed as effective additional tools for the management of thrombotic APS: hydroxychloroquine, statins, vitamin D, and sirolimus might be beneficial when added on the top of anticoagulation. Pregnant women with thrombotic APS should be switched to low-dose aspirin plus low molecular weight heparin at therapeutic dose. Despite adequate treatment, APS patients display a significant rate of recurrences; rituximab, eculizumab, and intravenous immunoglobulins are among the options to be considered for these patients. From 2013 to date, the kaleidoscope of therapeutic options in thrombotic APS has been enriched, but tangible improvements in the management of patients are still awaited.

Abstract
First described in 1983, antiphospholipid syndrome (APS) is an autoimmune condition characterized by the occurrence of recurrent arterial and/or venous thrombosis, and/or pregnancy morbidity, in the setting of persistent presence of antiphospholipid antibodies (aPL). While thrombosis is the most well-known pathogenic mechanism in this disorder, the relevance of some other mechanisms such as arterial stenosis is being increasingly recognized. Arterial stenosis has been first described in the renal arteries in patients with APS, however intracranial and coeliac arteries can also be involved with various and treatable clinical manifestations. The underlying pathophysiology of this stenotic arterial vasculopathy is not fully understood but some recent studies revealed new insights into the molecular mechanism behind this endothelial cell activation in APS. In this review, we discuss these newly discovered mechanisms and highlight the diagnostic and therapeutic modalities of the APS related arterial stenosis.

Abstract
The current mainstay of treatment in patients with thrombotic antiphospholipid syndrome (APS) is long-term anticoagulation, mainly with Vitamin K antagonist agents. Some recently available studies have created new ground for discussion about the possible discontinuation of anticoagulation therapy in patients with a history of thrombotic APS in whom antiphospholipid antibodies (aPL) are not detected any longer (i.e. aPL seroconversion). We report the main points discussed at the last CORA Meeting regarding the issue whether or not anticoagulation can be stopped after aPL seroconversion. In particular, we systematically reviewed the available evidence investigating the clinical outcome of APS patients with aPL seroconversion in whom anticoagulation was stopped when compared to those in whom therapy was continued regardless the aPL profile. Furthermore, the molecular basis for the aPL pathogenicity, the available evidence of non-criteria aPL and their association with thrombosis are addressed. To date, available evidence is still limited to support the indication to stop oral anticoagulation therapy in patients with a previous diagnosis of thrombotic APS who subsequently developed a negative aPL profile. The identification of the whole risk profile for cardiovascular manifestations and possibly of a second level aPL testing in selected patients with aPL might support the eventual clinical decision but further investigation is warranted.
