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.

Rheumatol Ther 2023; 10:7-34. [PMID: 36471199 PMCID: PMC9931974 DOI: 10.1007/s40744-022-00513-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Accepted: 11/15/2022] [Indexed: 12/12/2022] Open
Abstract
The objective of this work was to conduct a systematic literature review (SLR) and meta-analysis (MA) to evaluate the relative risk (RR) of venous thromboembolism (VTE) events, including deep vein thrombosis (DVT) and pulmonary embolism (PE), in patients with systemic lupus erythematosus (SLE) compared with patients without SLE, as well as the absolute risk (AR) (measured by incidence proportion) and incidence rate (IR) of VTE events in patients with SLE. The SLR was conducted using Embase, MEDLINE, and MEDLINE In-Process to identify observational studies evaluating the risk of VTE, DVT, and PE events in adult patients with SLE compared with the general population, published January 2000 to September 2020. Random-effects models were used as the primary approach in the MA. Heterogeneity was assessed on the basis of the I2 value. Sensitivity analyses were performed to assess the robustness of results to various conditions, and subgroup analysis was performed for the AR of VTE by antiphospholipid status (aPLs) and antiphospholipid syndrome (APS). Of the 50 publications included for data extraction, 44 contained data for consideration in the MA of any one of the measures of interest (RR, AR, or IR) for VTE, DVT, or PE. The pooled RR indicates statistically significantly higher risk of VTE (RR 4.38, 95% confidence interval 2.63-7.29) in patients with SLE compared with the general population. Considerable heterogeneity was present in nearly all MA (I2 = 75-100%). Moreover, a higher pooled AR of VTE was estimated in patients with SLE with aPLs (n/N = 0.13) and APS (n/N = 0.63) compared with patients with SLE without aPLs/APS (n/N = 0.07). Overall, there was evidence of an increased risk of VTE, DVT, and PE in patients with SLE compared with the general population.

Abstract
PURPOSE To analyze the antiphospholipid antibody (aPL) persistence over time in patients with antiphospholipid syndrome (APS) and its association with clinical recurrence and to identify predictors of aPL persistence over time. PATIENTS AND METHODS 200 patients with a diagnosis of APS and at least three follow-up aPL determinations were included. Persistent aPL profile was defined as the presence of lupus anticoagulant (LAC) and/or IgG/IgM anticardiolipin (aCL) and/or IgG/IgM anti-β2 glycoprotein-I (aβ2GPI) (> 99th percentile) antibodies in at least 66% of follow-up measurements. Multilevel mixed-effect generalized linear models with logit link were used. RESULTS 112 (56%) patients maintained persistent aPL profiles over time, while 88 (44%) were transient. Median follow-up time was 172.5 months. Follow-up time did not affect the odds of aPL persistence in multivariate analysis (p = 1.00). Baseline triple aPL positivity [OR 78 (95%CI 16.9-359.7, p < 0.001)] and double aPL positivity [OR = 7.6 (95%CI 3.7-15.7, p < 0.001)] correlated with persistent aPLs over time, while isolated LAC [OR = 0.26 (95% CI 0.08-0.49, p = 0.002)] or isolated IgG/IgM aCL [OR = 0.20 (95% CI 0.11-0.59, p = 0.004)] positivity, were predictors of transient aPL profile. Patients with persistent aPLs had higher rate of clinical recurrence in comparison to patients with transient aPLs [OR = 2.48 (95%CI 1.34-4.58, p = 0.003)]. CONCLUSIONS More than half of patients with baseline medium-high titer aPL positivity had persistent positive aPLs over time. Patients with persistent aPLs were more prone to present recurrence of clinical manifestations. Multiple aPL positivity increased the odds of a persistent aPL profile over time, while isolated LAC and aCL positivity decreased it.

Abstract
ObjectivesIschemic cerebrovascular disease (ICVD) is one of the most common and severe complications in systemic lupus erythematosus (SLE). We aim to explore the risk factors for ICVD in SLE and to assess their associated clinical characteristics.MethodsIn this study, 44 lupus patients with ICVD (ICVD-SLE) and 80 age- and sex-matched lupus patients without ICVD (non-ICVD-SLE) who were hospitalized in our center between 2014 and 2021 were enrolled. A comprehensive set of clinical and socio-demographic data was recorded. In the ICVD-SLE group, the modified Rankin score (mRS) at 90 days after the occurrence of ICVD, the brain MRI, and arterial ultrasonography findings were collected. Group comparisons were made with continuous variables using an independent t-test or the Mann–Whitney test, and with categorical variables using the chi-square test or Fisher exact test. Multivariate logistic regression analysis was performed to identify the risk factors for ICVD in SLE. Patients with ICVD-SLE were divided into three subgroups according to the gradations of intracranial arterial stenosis (ICAS). The subgroup comparisons were performed by one-way ANOVA test or Kruskal–Wallis test.ResultsOf the 44 patients with ICVD, 45% had a large-vessel ischemic stroke, 50% had a symptomatic lacunar stroke, and 9% had a transient ischemic attack. 2 (4.5%) had both large-vessel ischemic stroke and symptomatic lacunar stroke. Multivariate logistic regression analysis showed that cutaneous vasculitis (OR=7.36, 95% CI=2.11–25.65), anticardiolipin antibody (aCL) (OR=4.38, 95% CI=1.435–13.350), and lupus anticoagulant (LA) (OR=7.543,95% CI=1.789–31.808) were the risk factors, and hydroxychloroquine (HCQ) therapy (OR=0.198, 95% CI=0.078–0.502) was the protective factor, after controlling for confounders. During the analysis of the subgroups, no significant difference was observed between the patients in the group without internal carotid arterial occlusion (ICAS) and those with severe ICAS except for diagnostic delay. However, patients in the moderate ICAS group were older when SLE occurred (P<0.01), had a longer diagnostic delay (P<0.01), a lower percentage of hypocomplementemia (P=0.05) and steroids and HCQ therapy (P=0.01, P=0.05, respectively), a trend toward lower mRS score, but a higher incidence of carotid atherosclerotic plaque (P<0.01), when compared with the other two subgroups.ConclusionCutaneous vasculitis and antiphospholipid antibodies (aPLs) are associated with an increased risk of ICVD, while HCQ therapy may provide protection against ICVD in SLE. The ICVD in younger lupus patients is associated with complement-mediated inflammation and poorer outcome, and require immunosuppressive therapy, whereas the ICVD in elderly patients are characterized by moderate ICAS and carotid atherosclerotic plaques.

Abstract
OBJECTIVE To develop recommendations for cardiovascular risk (CVR) management in gout, vasculitis, systemic sclerosis (SSc), myositis, mixed connective tissue disease (MCTD), Sjögren's syndrome (SS), systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). METHODS Following European League against Rheumatism (EULAR) standardised procedures, a multidisciplinary task force formulated recommendations for CVR prediction and management based on systematic literature reviews and expert opinion. RESULTS Four overarching principles emphasising the need of regular screening and management of modifiable CVR factors and patient education were endorsed. Nineteen recommendations (eleven for gout, vasculitis, SSc, MCTD, myositis, SS; eight for SLE, APS) were developed covering three topics: (1) CVR prediction tools; (2) interventions on traditional CVR factors and (3) interventions on disease-related CVR factors. Several statements relied on expert opinion because high-quality evidence was lacking. Use of generic CVR prediction tools is recommended due to lack of validated rheumatic diseases-specific tools. Diuretics should be avoided in gout and beta-blockers in SSc, and a blood pressure target <130/80 mm Hg should be considered in SLE. Lipid management should follow general population guidelines, and antiplatelet use in SLE, APS and large-vessel vasculitis should follow prior EULAR recommendations. A serum uric acid level <0.36 mmol/L (<6 mg/dL) in gout, and disease activity control and glucocorticoid dose minimisation in SLE and vasculitis, are recommended. Hydroxychloroquine is recommended in SLE because it may also reduce CVR, while no particular immunosuppressive treatment in SLE or urate-lowering therapy in gout has been associated with CVR lowering. CONCLUSION These recommendations can guide clinical practice and future research for improving CVR management in rheumatic and musculoskeletal diseases.

Abstract
VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome is a recently described autoinflammatory syndrome characterized by diffuse inflammatory manifestations, predisposition to hematological malignancy, and an association with a high rate of thrombosis. VEXAS is attributed to somatic mutations in the UBA1 gene in hematopoietic stem and progenitor cells with myeloid restriction in mature forms. The rate of thrombosis in VEXAS patients is approximately 40% in all reported cases to date. Venous thromboembolism predominates thrombotic events in VEXAS. These are classified as unprovoked in etiology, although systemic and vascular inflammation are implicated. Here, we review the clinical and laboratory characteristics in VEXAS that provide insight into the possible mechanisms leading to thrombosis. We present knowledge gaps in the mechanisms and management of VEXAS-associated thromboinflammation and propose areas for future investigation in the field.

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
Background/Purpose Loss of positivity of antiphospholipid antibodies has been observed in clinical practice post-thrombosis in patients with SLE with secondary antiphospholipid syndrome (APS). Our study defined the frequency of this loss and the duration before positivity recurred. Methods In this prospective study, patients with SLE having at least two positive antiphospholipid markers prior to thrombosis and at least 1 year of follow-up after thrombosis were included. Antiphospholipid markers included lupus anticoagulant (dilute Russell viper venom test >45 s followed by mixing and confirmatory tests) and/or anticardiolipin titre (aCL IgG ≥20, aCL IgM ≥20 and/or aCL IgA ≥20). The percentage of visits with positive antiphospholipid markers after thrombosis was calculated. For patients with a negative antiphospholipid marker any time after thrombosis, survival estimates were performed to calculate the time to return of antiphospholipid positivity. Results In APS due to SLE, complete loss of antiphospholipid positivity post-thrombosis was up to 41% for aCL IgG, 51% for IgM and 50% for IgA, but only 20% for those with lupus anticoagulant. Of those who at some point lost aCL IgG or became negative for lupus anticoagulant, the majority (60% and 76%, respectively) reacquired the antibody within 5 years. In contrast, of those who lost aCL IgM or IgA, fewer reacquired it within 5 years (37% and 17%, respectively). Conclusion Intermittent positivity of antiphospholipid antibodies is present in APS due to SLE. These fluctuations make it difficult to decide on length of anticoagulation. Lupus anticoagulant is more likely to persist post-thrombosis.

Benign and malignant hematologic manifestations in patients with VEXAS syndrome due to somatic mutations in UBA1. Blood Adv 2021; 5:3203-3215.

Abstract
Somatic mutations in UBA1 involving hematopoietic stem and myeloid cells have been reported in patients with the newly defined VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome. Here, we report clinical hematologic manifestations and unique bone marrow (BM) features in 16 patients with VEXAS. All patients were male and had a history of severe autoinflammatory and rheumatologic manifestations and a somatic UBA1 mutation (p.Met41). Ten patients had hematologic disorders: myelodysplastic syndrome (MDS; 6 of 16), multiple myeloma (2 of 16), monoclonal gammopathy of undetermined significance (2 of 16), and monoclonal B-cell lymphocytosis (2 of 16), and a few of those patients had 2 co-existing clonal processes. Although macrocytic anemia (100%) and lymphopenia (80%) were prevalent in all patients with VEXAS, thrombocytopenia and neutropenia were more common in patients with progression to MDS. All BMs in VEXAS patients had prominent cytoplasmic vacuoles in myeloid and erythroid precursors. In addition, most BMs were hypercellular with myeloid hyperplasia, erythroid hypoplasia, and varying degrees of dysplasia. All patients diagnosed with MDS were lower risk (low blast count, very good to intermediate cytogenetics) according to standard prognostic scoring with no known progression to leukemia. In addition, 10 of 16 patients had thrombotic events, including venous thromboembolism and arterial stroke. Although VEXAS presents symptomatically as a rheumatologic disease, morbidity and mortality are associated with progression to hematologic disease. Given the increased risk of developing MDS and multiple myeloma, surveillance for disease progression is important.

Abstract
OBJECTIVE We evaluated which aPL combinations increase the risk of future thrombosis in patients with SLE. METHODS This prospective cohort study consisted of SLE patients who had been tested for all seven aPL (LA, aCL isotypes IgM, IgG and IgA, and anti-β2-glycoprotein I isotypes IgM, IgG and IgA). Pooled logistic regression was used to assess the relationship between aPL and thrombosis. RESULTS There were 821 SLE patients with a total of 75 048 person-months of follow-up. During the follow-up we observed 88 incident cases of thrombosis: 48 patients with arterial, 37 with venous and 3 with both arterial and venous thrombosis. In individual models, LA was the most predictive of any [age-adjusted rate ratio 3.56 (95% CI 2.01, 6.30), P < 0.0001], venous [4.89 (2.25, 10.64), P < 0.0001] and arterial [3.14 (1.41, 6.97), P = 0.005] thrombosis. Anti-β2-glycoprotein I IgA positivity was a significant risk factor for any [2.00 (1.22, 3.3), P = 0.0065] and venous [2.8 (1.42, 5.51), P = 0.0029] thrombosis. Only anti-β2-glycoprotein I IgA appeared to add significant risk to any [1.73 (1.04, 2.88), P = 0.0362] and venous [2.27 (1.13, 4.59), P = 0.0218] thrombosis among those with LA. We created an interaction model with four categories based on combinations of LA and other aPL to look at the relationships between combinations and the risk of thrombosis. In this model LA remained the best predictor of thrombosis. CONCLUSION Our study demonstrated that in SLE, LA remained the best predictor of thrombosis and adding additional aPL did not add to the risk, with the exception of anti-β2-glycoprotein I IgA.

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
OBJECTIVE The APS ACTION Registry studies long-term outcomes in persistently antiphospholipid antibody (aPL)-positive patients. Our primary objective was to determine whether clinically meaningful aPL profiles at baseline remain stable over time. Our secondary objectives were to determine (1) whether baseline characteristics differ between patients with stable and unstable aPL profiles, and (2) predictors of unstable aPL profiles over time. METHODS A clinically meaningful aPL profile was defined as positive lupus anticoagulant (LAC) test and/or anticardiolipin (aCL)/anti-β2 glycoprotein-I (anti-β2-GPI) IgG/M ≥ 40 U. Stable aPL profile was defined as a clinically meaningful aPL profile in at least two-thirds of follow-up measurements. Generalized linear mixed models with logit link were used for primary objective analysis. RESULTS Of 472 patients with clinically meaningful aPL profile at baseline (median follow-up 5.1 yrs), 366/472 (78%) patients had stable aPL profiles over time, 54 (11%) unstable, and 52 (11%) inconclusive. Time did not significantly affect odds of maintaining a clinically meaningful aPL profile at follow-up in univariate (P = 0.906) and multivariable analysis (P = 0.790). Baseline triple aPL positivity decreased (OR 0.25, 95% CI 0.10-0.64, P = 0.004) and isolated LAC test positivity increased (OR 3.3, 95% CI 1.53-7.13, P = 0.002) the odds of an unstable aPL profile over time. CONCLUSION Approximately 80% of our international cohort patients with clinically meaningful aPL profiles at baseline remain stable at a median follow-up of 5 years; triple aPL-positivity increase the odds of a stable aPL profile. These results will guide future validation studies of stored blood samples through APS ACTION Core Laboratories.

Abstract
OBJECTIVE To compare the influence of antiphospholipid antibodies (aPL) on global and cardiovascular damage in patients with systemic lupus erythematosus (SLE) diagnosed before and after year 2000. METHODS 286 patients from the Lupus-Cruces cohort with a minimum follow-up of 5 years, divided into two sub-cohorts according to the date of diagnosis, before 2000 (<2000) and from 2000 on (≥2000). We compared the mean SDI score and global and cardiovascular damage-free survival rates in the presence/absence of aPL in both sub-cohorts. Variables potentially modulating damage among aPL-positive patients were analysed. RESULTS The sub-cohorts were comparable for demographic and lupus-related variables except for treatment variables: the ≥2000 sub-cohort received lower doses of prednisone and more hydroxychloroquine, low-dose aspirin, statins, immunosuppressive agents and Vitamin D. aPL-positive patients in the <2000, but not in the ≥2000 sub-cohort, accrued more damage compared with aPL-negative. In the <2000 sub-cohort, the adjusted HRs for global and cardiovascular damage in aPL-positive vs. aPL-negative patients were 1.98 (95% CI 1.24-3.14) and 9.3 (95% CI 3.24-26.92), respectively. No differences in damage were seen between aPL-positive and aPL-negative patients in the ≥2000 sub-cohort. Hypertension (HR 4.64, 95%CI 1.33-16.19), lupus anticoagulant (HR 3.85, 95%CI 1.1-13.41) and the number of months on hydroxychloroquine (HR 0.97, 95%CI 0.95-0.99) were independent predictors of vascular damage in the combined analysis of all aPL-positive patients. CONCLUSION The effects of aPL on damage accrual in SLE patients have been reduced over the last years. The widespread use of hydroxychloroquine and a better thromboprophylaxis are likely causing this change.

Abstract
Unplanned pregnancies account for a large number of encountered pregnancies. One of the reasons for this is the lack of counseling surrounding contraception and subsequently lack of contraception use. A conversation during a regular CKD office visit of simply asking a woman what her plans are regarding pregnancy can lead to further discussion on timing of pregnancy and contraception and eventually safer outcomes for both the mother and fetus. Individual preference, as well as comorbid conditions, should be taken into account when deciding on optimal contraceptive methods. One must remember that contraception counseling and initiation of contraception should not be wrapped up in a single office visit, and there must be continued follow-up to ensure that the woman is using the contraceptive method correctly to prevent any future unplanned pregnancy.

Abstract
Antiphospholipid syndrome is an autoimmune systemic disorder characterized by arterial, venous, or small vessel thrombosis and/or recurrent early pregnancy loss, fetal loss, or pregnancy morbidity in the setting of documented persistent antiphospholipid antibodies that include the lupus anticoagulant, or moderate-high titer anticardiolipin, or anti-β2Glycoprotein I antibodies. Associated clinical manifestations include livedo reticularis, cutaneous ulcerations, thrombocytopenia, hemolytic anemia, valvular heart disease, and nephropathy. The degree of risk associated with antiphospholipid antibody depends on the characteristics of the antiphospholipid antibody profile and on the presence of additional thrombotic risk factors. Current standard treatment for unprovoked thrombosis is long-term warfarin or other vitamin K antagonist therapy. Treatment to prevent recurrent obstetric complications is low-dose aspirin and prophylactic heparin, usually low-molecular-weight heparin. Optimal treatment for standard therapy failures or for certain nonthrombotic manifestations is uncertain, although nonanticoagulation therapies that address multiple demonstrated mechanisms of disease are being explored.

Abstract
Although numerous studies have addressed the safety and effectiveness of hormonal contraceptive use in healthy women, data regarding women with underlying medical conditions or other special circumstances are limited. The U.S. Medical Eligibility Criteria (USMEC) for Contraceptive Use, 2016 (), which has been endorsed by the American College of Obstetricians and Gynecologists, is a published guideline based on the best available evidence and expert opinion to help health care providers better care for women with chronic medical problems who need contraception. The goal of this Practice Bulletin is to explain how to use the USMEC rating system in clinical practice and to specifically discuss the rationale behind the ratings for various medical conditions. Contraception for women with human immunodeficiency virus (HIV) (); the use of emergency contraception in women with medical coexisting medical conditions, including obesity, (); and the effect of depot medroxyprogesterone acetate (DMPA) on bone health () are addressed in other documents from the American College of Obstetricians and Gynecologists.

Abstract
The antiphospholipid syndrome (APS) is an autoimmune disease characterized by the occurrence of venous and/or arterial thrombosis and pregnancy morbidity in the presence of pathogenic autoantibodies known as antiphospholipid antibodies (aPL). APS may be associated with other diseases, mainly systemic lupus erythematosus (SLE). The presence or absence of SLE might modify the clinical or serological expression of APS. Apart from the classical manifestations, APS patients with associated SLE more frequently display a clinical profile with arthralgias, arthritis, autoimmune hemolytic anemia, livedo reticularis, epilepsy, glomerular thrombosis, and myocardial infarction. The management of patients with SLE and APS/aPL should include an accurate stratification of vascular risk factors. Low dose aspirin and hydroxychloroquine should be considered as primary prophylaxis. In high risk situations, such as surgery, prolonged immobilization, and puerperium, the prophylaxis should be potentiated with low molecular weight heparin. The challenge of treating patients with a previous vascular event (secondary prophylaxis) is the choice of treatment (anti-platelet agents, anticoagulation with vitamin K antagonists or combined therapy) and its duration, based on individual risk stratification and the site of vascular presentation. The role of novel anticoagulants in APS patients is still to be clearly defined. Novel approaches are needed since the prognosis of SLE patients with APS/aPL is still worse than that of SLE patients with negative aPL. The goal for the future is to improve the outcome of these patients by means of early recognition and optimal preventative treatment.

Abstract
Antiphospholipid antibody syndrome (APS) is an autoimmune acquired thrombophilia characterized by recurrent thrombosis and pregnancy morbidity in the presence of antiphospholipid antibodies (aPL). APS can be primary, if it occurs in the absence of any underlying disease, or secondary, if it is associated with another autoimmune disorder, most commonly systemic lupus erythematosus. The exact pathogenetic mechanism of APS is unknown, but different, not mutually exclusive, models have been proposed to explain how anti-PL autoantibodies might lead to thrombosis and pregnancy morbidity. Diagnosis of APS requires that a patient has both a clinical manifestation (arterial or venous thrombosis and/or pregnancy morbidity) and persistently positive aPL, but the clinical spectrum of the disease encompasses additional manifestations which may affect every organ and cannot be explained exclusively by a prothrombotic state. Treatment for aPL-positive patients is based on the patient's clinical status, presence of an underlying autoimmune disease, and history of thrombotic events. In case of aPL positivity without previous thrombotic events, the treatment is mainly focused on reduction of additional vascular risk factors, while treatment of patients with definite APS is based on long-term anticoagulation. Pregnancy complications are usually managed with low-dose aspirin in association with low molecular weight heparin. Refractory forms of APS could benefit from adding hydroxychloroquine and/or intravenous immunoglobulin to anticoagulation therapy. Promising novel treatments include anti-B cell monoclonal antibodies, new-generation anticoagulants, and complement cascade inhibitors. The objective of this review paper is to summarize the recent literature on APS from pathogenesis to current therapeutic options.

Abstract
Doctors often have difficulties in clinical diagnosis and clinical stage of thromboangiitis obliterans (TAO). Immunolesion was important in the initiation and progression of various kinds of vasculitis diseases, including TAO. Several kinds of immune complexes were developed by immunolesion, including anti-neutrophil cytoplasmic antibodies (ANCA) and anticardiolipin antibodies (ACA). Our aim was to determine if it is an effective way for clinical diagnosis and clinical stage of TAO by detection of the presence of ANCA and ACA in blood serum of patients with TAO and the relationship among the presence of ANCA, ACA and patients with different grades of TAO. Blood samples and clinical characteristics were collected from 38 patients with Rutherford grade I TAO, 30 patients with Rutherford grade II–III TAO, 75 patients with arteriosclerosis obliterans (ASO) and 65 healthy volunteers. Their serum samples were investigated for ANCA by indirect immunofluorescent (IIF), and for ACA and ANCA specificity antigens including reactivity to proteinase 3(PR3), myeloperoxidase (MPO), cathepsin G (CG), bactericidal/permesbility-increasing protein (BPI), elastase (HLE) and lactoferrin (LF) by enzyme linked immunosorbent assay (ELISA). (1) ANCA positive rate and titre were much higher in cases with Rutherford grade I TAO (52.6%, 20/38, 0.386 ± 0.458) and Rutherford grade II–III TAO (73.3%, 22/30, 0.847 ± 0.658) than those in cases with ASO (4%, 3/75, 0.011 ± 0.002) and healthy volunteers (0%,0/65, 0.010 ± 0.002) (P < 0.01). ANCA positive rate and titre were higher in cases with Rutherford grade II–III TAO (73.3%, 22/30, 0.847 ± 0.658) than those in cases with Rutherford grade I TAO (52.6%, 20/38, 0.386 ± 0.458) (P < 0.05). (2) ACA concentration was much higher in cases with Rutherford grade I TAO (270.13 ± 13.05 IU/mL) and Rutherford grade II–III TAO (279.33 ± 19.98 IU/mL) than that in cases with ASO (236.85 ± 17.32 IU/mL) and healthy volunteers (229.16 ± 15.55 IU/mL) (P < 0.05) respectively. (3) In 42 cases of ANCA-positive samples, there were 20 cases reacted with MPO, 14 cases reacted with LF, five cases reacted with HLE, five cases reacted with BPI and no one reacted with PR3 and CG. All cases were Rutherford grade II–III TAO. Our results indicate that ANCA, ANCA specificity antigens and ACA were detected susceptibly and availably in patients with TAO. Thus, detection of ANCA, ANCA specificity antigens and ACA was helpful for clinical diagnosis of TAO and detection of ANCA and ANCA specificity antigens was helpful for clinical staging of TAO. They are important assistance for clinical diagnosis and stage of TAO.

Elevated partial antiphospholipid score is a strong risk factor for thrombosis in patients with systemic lupus erythematosus: a validation study. Clin Rheumatol 2016; 35:333-40. [PMID: 26753544 DOI: 10.1007/s10067-015-3159-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2015] [Revised: 12/18/2015] [Accepted: 12/22/2015] [Indexed: 10/22/2022]
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.

The clinical relevance of the IgM isotype of antiphospholipid antibodies in the vascular antiphospholipid syndrome. Thromb Res 2015; 136:883-6. [PMID: 26410418 DOI: 10.1016/j.thromres.2015.08.019] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2015] [Revised: 08/12/2015] [Accepted: 08/28/2015] [Indexed: 12/12/2022]
Abstract
OBJECTIVES Because it has been suggested that the IgM isotype of antiphospholipid (aPL) antibodies should no longer be included in the laboratory criteria for antiphospholipid syndrome (APS) classification, we assess the clinical relevance of IgM isotype of aPL in a cohort of patients with vascular APS. PATIENTS/METHODS Mean age, sex, the presence of autoimmune diseases other than systemic lupus erythematosus, risk factors for thrombosis, the type/s and site/s of thromboembolic events, the levels of C3 and C4, and autoantibody profile were evaluated in a large cohort of persistently aPL positive patients fulfilling the Sydney criteria for APS. Patients with isolated IgM isotype were compared for each variable with those with any other aPL antibody combination. RESULTS One hundred six patients were assessed; of these 55 (51.9%) had venous thromboembolism, 48 (45.3%) arterial thrombosis, and 3 (2.8%) small vessel thrombosis. Positivity to only IgM aPL made possible to classify 13 patients (12.3%) as vascular APS. In all cases the presence of IgM aPL was at medium-high titer, confirmed, and found to be stable in the time. There were four patients with retinal thrombosis (3.8%) and the prevalence of this event was significant in the isolated IgM isotype positive patients (p=0.005). CONCLUSIONS Data from this investigation give clinical value to the IgM isotype of aPL and suggest to consider aCL and anti-β2GPI of IgM class as valid laboratory criteria for APS classification, especially when they are associated and stable overtime.

Intractable headaches, ischemic stroke, and seizures are linked to the presence of anti-β2GPI antibodies in patients with systemic lupus erythematosus. PLoS One 2015; 10:e0119911.

Abstract
Background Neuropsychiatric systemic lupus erythematosus (NPSLE) is a common and potentially fatal manifestation of SLE. Antiphospholipid antibodies (aPL) such as lupus anticoagulant (LA), anticardiolipin (aCL) and antibodies to β2glycoprotein I (anti-β2GPI), the most important aPL antigen, are thought to play a role in some forms of NPSLE. As of yet, their specific roles in NPSLE manifestations remain to be elucidated. Methodology/Principal Findings 57 SLE patients (53 women) were assessed for LA, aCL and anti-β2GPI twice, to determine persistent positivity. All patients were examined by neurology and psychiatry specialists. 69 healthy subjects were assessed as controls. NPSLE was diagnosed in 74% of patients. Headaches were the most prevalent manifestation of NPSLE (39%), followed by cerebrovascular disease (CVD) (23%), depressive disorders (19.0%), and seizures (14%). NPSLE and non-NPSLE patients showed comparable SLE activity and corticosteroid use. In 65% of patients neuropsychiatric manifestations preceded SLE diagnosis. aPL profiles of NPSLE patients and non-NPSLE patients were similar. Headaches and ischemic stroke were independently associated with anti-β2GPI-IgM (OR=5.6; p<0.05), and seizures were linked to anti-β2GPI-IgG (OR=11.3; p=0.01). Conclusions In SLE patients, neuropsychiatric manifestations occur frequently and early, often before the disease is diagnosed. Autoantibodies to β2GPI are linked to non-specific headaches, ischemic stroke and seizures, and show a better predictive value than aCL and LA. These findings may help to improve the diagnosis of NPSLE and should prompt further studies to characterize the role of anti-β2GPI in the pathogenesis of this condition.

Abstract
OBJECTIVE To determine the prevalence of antiphospholipid antibodies (aPL) and their association with obstetric outcomes in women with preeclampsia. METHODS The study included 150 patients. Clinical variables, risk factors, and severity criteria for preeclampsia and aPL were analyzed. RESULTS We found aPL in 4% of patients without risk factors for preeclampsia and in no women with risk factors (p = 0.03). Fifty percent of aPL-positive patients had a fetus with intrauterine growth restriction versus 13.9% (p = 0.04). No relation between aPL and severe preeclampsia was found. CONCLUSION The prevalence of aPL among women with preeclampsia is low. aPL can predispose women without risk factors to preeclampsia.

Abstract
Context. Antiphospholipid antibodies syndrome is an autoimmune disorder that is characterized by the association between presence of antiphospholipid antibodies and risk of thrombosis and/or pregnancy morbidity. Objectives. To systematically review the evidence for primary prophylaxis in patients with antiphospholipids antibodies syndrome or APS with or without other traditional risk factors of thrombosis when they did not have any thrombotic event yet. Methods. PubMed, the Cochrane Library, and Allied Health Literature were searched for studies that examined the efficacy and safety of primary prophylaxis in aPL patients from 1990 to February 2013. We examined literature looking at patients with aPLs with other risk factors for thrombosis and aPLs with no additional risk factors for thrombosis. Conclusion. We concluded that, in patients with aPLs, primary prophylaxes with HCQ and aspirin have been observed to reduce the frequency of thrombotic events in the case of asymptomatic aPL-positive patients with SLE. We also in this study concluded that LDA was effective in patients with autoimmune diseases. Independent cardiovascular risk factors include autoimmune defects such as SLE, rheumatoid arthritis, and atherosclerosis, where overall venous thrombosis will be induced by systemic inflammation. This review concludes that HCQ is an effective primary approach when compared to aspirin.

Abstract
INTRODUCTION Antiphospholipid syndrome (APS) is associated with the risk of both arterial and venous thrombosis. However, it is not known which factors might determine the location of thrombosis. MATERIALS AND METHODS To retrospectively characterize factors associated with the risk of arterial thrombosis in a cohort of APS patients. Analysis included laboratory and clinical criteria of APS, together with classical cardiovascular risk factors and the possible role of platelet integrin α₂β₁ (807 C/T) and α(IIb)β₃ (PI A1/2) genetic polymorphisms. We enrolled 163 APS patients (123 women and 40 men aged 21-75; mean age 43 years); 78 suffered from arterial thrombosis. RESULTS There were no significant differences in the frequency or titers of different antiphospholipid antibodies with the exception of slightly increased frequency of IgG anticardiolipin antibodies (ACL) in the arterial thrombosis group. Livedo reticularis was observed significantly more often in the arterial thrombosis group, particularly in stroke patients. In univariate analysis arterial thrombosis was associated with male gender (OR-2,201; p=0,033), arterial hypertension (OR-2,81; p=0,002) and hypercholesterolemia (OR-3,69; p=0,001). On multivariate analysis arterial hypertension (OR=1,78; p=0,008) and hypercholesterolemia (OR=2,001; p=0,002) remained as independent risk factors for arterial thrombosis. Platelet glycoprotein polymorphisms studied did not show any significant associations with arterial thrombosis in APS patients. CONCLUSIONS Among APS patients those with ACL IgG antibodies, having livedo reticularis, and suffering from hypertension an hypercholesterolemia are at the increased risk of arterial thrombosis.

Abstract
Prognosis studies provide important healthcare information. Clinicians use prognostic factors to predict disease progress, thus allowing individualization of disease management. Prognosis is the issue in many translational studies that aim to identify biomarkers to predict outcomes. In a clinical trial, researchers may use prognostic factors to sort patients into risk groups, to clarify the effects of a new therapeutic agent. Prognosis studies can have significant effects on clinical practice.

Abstract
The antiphospholipid syndrome (APS) is an autoimmune disorder presenting with tissue injury in various organs related to large- or small-vessel thrombosis associated with antiphospholipid and antiprotein/phospholipid complex antibodies. Although the pathophysiology, diagnosis, and clinical scenario may seem clear and straightforward, a more detailed examination reveals a more complex and uncertain picture related to the management of APS. This article reviews the current situation relating to APS therapy by evaluating the different clinical features of the syndrome ranging from thrombosis to pregnancy complications together with new strategies and pharmacological approaches.

Abstract
The antiphospholipid syndrome (APS) is defined by the presence of thrombosis and/or pregnancy morbidity in combination with the persistent presence of circulating antiphospholipid antibodies: lupus anticoagulant, anticardiolipin antibodies and/or anti-β2-glycoprotein I antibodies in medium to high titers. The management of thrombosis in patients with APS is a subject of controversy. This set of recommendations is the result of an effort to produce guidelines for therapy within a group of specialist physicians in Cardiology, Neurology, Hematology, Rheumatology and Internal Medicine, with a clinical and research focus on APS.

Abstract
BACKGROUND Nephropathy associated with antiphospholipid antibodies (aPL) has been proposed as a risk factor of worse renal prognosis in patients with systemic lupus erythematosus (SLE). The purpose of the current study was to evaluate the prevalence of aPL-associated nephropathy (aPLN) among patients with lupus nephritis and to describe their functional renal outcome. METHODS A total of 79 renal biopsies from 77 patients followed at the Hospital Clinic, Spain were analysed. Each renal biopsy was evaluated by a pathologist who was blinded to the aPL status. Thrombotic microangiopathy (TMA), fibrous intimal hyperplasia (FIH), fibrocellular arterial occlusion (FAO), focal cortical atrophy (FCA), and tubular thyroidization as lesions suggestive of aPLN were identified. RESULTS aPLN was found in nine (11.4%) biopsies. TMA was found in three (33.3%) cases whereas chronic aPLN, represented by FIH and FCA, was found in four (44.4%) and three (33.3%) cases, respectively. A significant association between the presence of aPL and aPLN was found (p = 0.003). Patients with lupus anticoagulant (LA) plus IgG anticardiolipin antibodies (aCL) showed an increased prevalence of aPLN (OR: 3.61, 95% CI 1.28-5.14; p = 0.002). Creatinine levels were significantly increased in patients with aPLN compared with those with aPL without aPLN (p = 0.038). However, no significant difference in complete remission, partial remission, not response, and established renal damage between groups was observed at the end of follow-up. CONCLUSIONS The aPL have an important role in the pathogenesis of renal lesions in SLE patients. Prospective studies are needed to address the role of aPLN in the long-term outcome of SLE patients with positive aPL.

Abstract
BACKGROUND The presence of antiphospholipid antibodies (aPLs) is associated with the clinical features of antiphospholipid syndrome (APS), which comprises venous and arterial thrombosis and pregnancy loss, and systemic lupus erythematosus (SLE). The prevalence of aPLs has been reported to be different in patient populations affected by either of these conditions. We performed a retrospective study to evaluate the prevalence and clinical associations of aPLs, including lupus anticoagulant (LAC), anticardiolipin (aCL), and anti-beta2-glycoprotein I antibodies (anti-beta2-GPI) in a cohort of Korean patients with SLE. METHODS This study included samples from 88 SLE patients for whom aPL testing had been advised between June 2006 and July 2009 at the Dong-A University Hospital. Serum and plasma samples were tested for LAC, aCL (IgG, IgM), and anti-beta2-GPI (IgG, IgM) antibodies. Clinical data from patients were obtained from a review of medical records. RESULTS LAC was the most common (34.1% of total patients, 30/88) antibody, followed by IgM aCL (31.8%, 28/88), IgG aCL (18.2%, 16/88), and IgM and IgG anti-beta2-GPI (both 5.7%, 5/88 each). Positivity for LAC was strongly associated with venous/arterial thrombosis (P=0.002). CONCLUSIONS LAC was the most common antibody detected in Korean SLE patients and is shown to have a significant association with the presence of venous/arterial thrombosis. The measurement of LAC may be clinically useful in identifying patients with SLE who are at a high risk for venous/arterial thrombosis.

Abstract
The antiphospholipid syndrome causes venous, arterial, and small-vessel thrombosis; pregnancy loss; and preterm delivery for patients with severe pre-eclampsia or placental insufficiency. Other clinical manifestations are cardiac valvular disease, renal thrombotic microangiopathy, thrombocytopenia, haemolytic anaemia, and cognitive impairment. Antiphospholipid antibodies promote activation of endothelial cells, monocytes, and platelets; and overproduction of tissue factor and thromboxane A2. Complement activation might have a central pathogenetic role. Of the different antiphospholipid antibodies, lupus anticoagulant is the strongest predictor of features related to antiphospholipid syndrome. Therapy of thrombosis is based on long-term oral anticoagulation and patients with arterial events should be treated aggressively. Primary thromboprophylaxis is recommended in patients with systemic lupus erythematosus and probably in purely obstetric antiphospholipid syndrome. Obstetric care is based on combined medical-obstetric high-risk management and treatment with aspirin and heparin. Hydroxychloroquine is a potential additional treatment for this syndrome. Possible future therapies for non-pregnant patients with antiphospholipid syndrome are statins, rituximab, and new anticoagulant drugs.

Abstract
Antiphospholipid syndrome (APS) is characterized by recurrent venous or arterial thromboses, fetal losses and thrombocytopenia in the presence of antiphospholipid antibodies, namely lupus anticoagulant, anticardiolipin antibodies or antibodies directed to various proteins, mainly β2 glycoprotein I, or all three. There is consensus in treating patients with APS and first venous thrombosis with oral anticoagulation to a target international normalized ratio (INR) of 2.0-3.0. A recent systematic review recommended a target INR of >3.0 in those patients with APS and arterial thrombosis. The approach in women with obstetric manifestations of APS is based on the use of aspirin plus heparin. The best treatment for patients with the catastrophic variant of the APS is a combination of anticoagulation, corticosteroids, and plasma exchange or intravenous immunoglobulins.

Abstract
Antiphospholipid syndrome is diagnosed when arterial or venous thrombosis or recurrent miscarriages occur in a person in whom laboratory tests for antiphospholipid antibodies (anticardiolipin antibodies and/or lupus anticoagulant and/or anti-beta 2-glycoprotein I) are positive. Despite the strong association between antiphospho-lipid antibodies and thrombosis, their pathogenic role in the development of thrombosis has not been fully elucidated. Novel mechanisms involving both the complement pathway and micro-particles have been described. The knowledge of these new pathogenic approaches might identify novel therapeutic targets and therefore may improve the management of these patients.

Abstract
The antiphospholipid syndrome (APS) is characterized by a wide variability in clinical manifestations. Recommendations for therapy are conditioned by the lack of appropriate studies, due either to methodological limitations or excessive selection of patients. There is consensus in treating patients with APS and first venous thrombosis with warfarin to a target international normalized ratio (INR) of 2.3-3.0. However, a recent systematic review including observational studies found patients with APS and stroke to be at a high risk of recurrent events. We thus recommend a target INR>3.0 in this group. Likewise, the optimal approach for women with obstetric manifestations of APS is not completely defined; some authors recommend universal aspirin plus heparin whereas others consider aspirin in monotherapy useful for women with recurrent early miscarriage only. Correction of vascular risk factors and a high-risk management of pregnancy, including Doppler studies of the uterine and umbilical vessels, are warranted. Hydroxychloroquine and statins are likely to become important in the future.
