Patients with DVT and primary antiphospholipid syndrome have worse obstetric outcomes than pregnant women with DVT and negative antiphospholipid antibodies: a retrospective cohort study.

Background: Pregnant women are at an increased risk of thromboembolism compared with non-pregnant women. Venous thrombosis is a manifestation of antiphospholipid syndrome (APS), an autoimmune thrombophilia associated with pregnancy morbidity.

Objectives: This study was designed to compare gestational outcomes of pregnant patients with deep venous thrombosis (DVT) and primary APS with outcomes of patients with DVT and negative results for antiphospholipid antibodies (aPLs).

Reasons for Breastfeeding Avoidance: A Multicenter Insight in Mothers With Systemic Lupus Erythematosus.

Background: Limited research exists on breastfeeding among women with systemic lupus erythematosus, despite known benefits of human milk.

Research Aim: To investigate reasons for breastfeeding avoidance among postpartum women with systemic lupus erythematosus.

Methods: This is a descriptive study, conducted in January 2023, combining retrospective pregnancy outcome data collection with a structured telephone questionnaire.

Predictors of Mortality in Antiphospholipid Antibody-Positive Patients: Prospective Results From Antiphospholipid Syndrome Alliance for Clinical Trials and International Networking Clinical Database and Repository.

Objective: The objective was to determine the mortality rate as well as the causes and predictors of death in antiphospholipid antibody (aPL)-positive patients with and without antiphospholipid syndrome (APS) classification.

Methods: The inclusion criterion for the multicenter international Antiphospholipid Syndrome Alliance for Clinical Trials and International Networking (APS ACTION) registry is positive aPLs according to the Revised Sapporo Classification Criteria tested within one year before enrollment. Patients are observed every 12 ± 3 months with clinical data and blood collection.

Early subclinical macular disease in asymptomatic patients with primary antiphospholipid syndrome: A quantitative multimodal retinal evaluation.

Purpose: To perform a quantitative multimodal evaluation in 25 patients with primary antiphospholipid syndrome (PAPS) without ocular complaints and to compare them with 25 healthy individuals.

Methods: A structural and functional ophthalmological evaluation using optical coherence tomography angiography (OCTA) and microperimetry (MP) exam in 25 patients with PAPS, followed at a tertiary rheumatology outpatient clinic, was performed. All ophthalmologic manifestations were documented and subsequent statistical analysis was performed for comparative purposes, with significance set at < 0.

Thrombosis recurrence and major bleeding in non-anticoagulated thrombotic antiphospholipid syndrome patients: Prospective study from antiphospholipid syndrome alliance for clinical trials and international networking (APS ACTION) clinical database and repository ("Registry").

Background: Long-term anticoagulant therapy is generally recommended for thrombotic antiphospholipid syndrome (TAPS) patients, however it may be withdrawn or not introduced in routine practice.

Objectives: To prospectively evaluate the risk of thrombosis recurrence and major bleeding in non-anticoagulated TAPS patients, compared to anticoagulated TAPS, and secondly, to identify different features between those two groups.

Patients/methods: Using an international registry, we identified non-anticoagulated TAPS patients at baseline, and matched them with anticoagulated TAPS patients based on gender, age, type of previous thrombosis, and associated autoimmune disease.

Comorbid association of obstructive sleep apnea (OSA) and thrombotic primary antiphospholipid syndrome (tPAPS): A more severe phenotype?

Objective: We aimed to evaluate the frequency of obstructive sleep apnea (OSA) in patients with thrombotic primary antiphospholipid syndrome (tPAPS), to investigate the performance of screening tools for OSA in this scenario and to compare clinical/laboratorial differences in tPAPS patients with and without OSA.

Methods: We consecutively enrolled patients with tPAPS to undergo sleep studies using a portable monitor. OSA was defined as apnea-hypopnea index ≥15 events/h.

Ocular retinal findings in asymptomatic patients with antiphospholipid syndrome secondary to systemic lupus erythematosus.

The objective is to perform a multimodal ophthalmological evaluation, including optical coherence angiography (OCTA), asymptomatic APS secondary to SLE (APS/SLE), and compare to SLE patients and control group (CG). We performed a complete structural/functional ophthalmological evaluation using OCTA/microperimetry exam in all participants. One hundred fifty eyes/75 asymptomatic subjects [APS/SLE (n = 25), SLE (n = 25), and CG (n = 25)] were included.

Associations Among Antiphospholipid Antibody Types, Isotypes, and Titers: An AntiPhospholipid Syndrome Alliance for Clinical Trials and InternatiOnal Networking (APS ACTION) Study.

Several antiphospholipid antibody (aPL) profiles ("triple" and lupus anticoagulant [LA] positivity) are associated with a higher risk for clinical manifestations of antiphospholipid syndrome (APS). Further risk is correlated with higher levels of anticardiolipin antibody (aCL) and anti-β glycoprotein-I antibody (aβGPI), and with aPL persistence. Given that the 3 aPL tests detect partially overlapping sets of antibodies, the primary goal of this study was to characterize the associations among aPL tests using AntiPhospholipid Syndrome Alliance for Clinical Trials and InternatiOnal Networking (APS ACTION) core laboratory data.

Ocular involvement in primary antiphospholipid syndrome: results of an extensive ophthalmological evaluation performed in the APS-Rio cohort.

Objective: To study ophthalmological manifestations in a well-characterized primary antiphospholipid syndrome (PAPS) cohort (APS-Rio) and compare them with a healthy control group.

Methods: We examined PAPS patients and controls with an extensive ophthalmological evaluation, which included anamnesis, visual acuity, slit-lamp biomicroscopy, binocular indirect ophthalmoscopy, and retinography of the anterior and posterior segments of the eye. PAPS group also underwent angiography exam and optical coherence tomography using spectral domain technology (SD-OCT).

Ocular findings in asymptomatic patients with primary antiphospholipid syndrome.

Background: Primary antiphospholipid syndrome (PAPS) is characterized by the presence of antiphospholipid antibodies (aPL), repetitive fetal loss, and arterial/venous thrombosis and no association with other autoimmune rheumatic disease. Ocular involvement can also occur including retinal vascular thrombosis and neuro-ophthalmological manifestations, such as optic neuropathy and amaurosis fugax. Early detection of ocular changes is crucial to minimize functional loss.

Immunogenicity, safety, and antiphospholipid antibodies after SARS-CoV-2 vaccine in patients with primary antiphospholipid syndrome.

Objective: Coronavirus disease 19 (COVID-19) has an increased risk of coagulopathy with high frequency of antiphospholipid antibodies (aPL). Recent reports of thrombosis associated with adenovirus-based vaccines raised concern that SARS-CoV-2 immunization in primary antiphospholipid syndrome (PAPS) patients may trigger clotting complications. Our objectives were to assess immunogenicity, safety, and aPL production in PAPS patients, after vaccinating with Sinovac-CoronaVac, an inactivated virus vaccine against COVID-19.

CoaguChek® XS versus standard laboratory prothrombin time for anticoagulant monitoring in patients with antiphospholipid syndrome.

Introduction: The standard of care for thrombotic antiphospholipid syndrome (APS) is anticoagulation with vitamin K antagonists (VKAs). Prothrombin time, and its corresponding international normalized ratio (INR), is the laboratory test routinely performed to assess anticoagulation. Self-management of VKA therapy using point-of-care (POC) devices seems to be an attractive option.

Distinct features of youth-onset primary antiphospholipid syndrome.

Background: Characteristics of primary APS (PAPS) in the youth population have never been studied. In contrast with children, pregnancy is genuinely relevant in the youth age, and understanding clinical characteristics of PAPS patients within this specific age stratum may also provide insights regarding the well-known risk of poor obstetric outcomes during the adolescence.

Objective: To evaluate clinical and laboratory characteristics of patients with youth-onset PAPS (15-24 years) and compare them with adult-onset PAPS (over 24 years old).

Avoiding misclassification of thrombotic primary antiphospholipid syndrome as systemic lupus erythematosus (SLE): What are the best-performing SLE classification criteria?

Background: Systemic lupus erythematosus (SLE) and Primary Antiphospholipid Syndrome (PAPS) overlap clinical and immunological features. Therefore, misclassification of PAPS patients as SLE is a concern. The ACR/EULAR 2019 SLE classification has never been studied in PAPS.

Ophthalmologic manifestations in primary antiphospholipid syndrome patients: A cross-sectional analysis of a primary antiphospholipid syndrome cohort (APS-Rio) and systematic review of the literature.

Objective: There is a broad spectrum of eye involvement in antiphospholipid syndrome (APS). The majority of descriptions are presented as case reports that include mostly APS patients secondary to systemic lupus erythematosus (SLE), with no compelling evidence in primary APS (PAPS). This study aimed to describe ocular manifestations in our well-defined PAPS cohort (APS-Rio) and then perform a systematic literature review (SLR) of ocular manifestations in patients with APS or positivity to aPL without SLE.

New and upcoming treatments in antiphospholipid syndrome: A comprehensive review.

Current therapeutic recommendations for thrombosis prevention in patients with antiphospholipid syndrome (APS) are limited to anticoagulation with vitamin K antagonists (VKA) or heparins and to anti-platelet aggregating agents. Maintaining optimized anticoagulation to prevent recurrent thrombosis or bleeding remains a therapeutic challenge. Although there are important ongoing trials with direct oral anticoagulants, they still aim the same target.

The interplay between tuberculosis and systemic lupus erythematosus.

Purpose Of Review: Tuberculosis (TB) is a millenarian chronic infection and, yet, remains a major global health problem. The interaction between systemic lupus erythematosus (SLE) and TB is complex, as one seems to be a risk factor for the development of the other. SLE patients are more likely to develop TB, that is more frequently extrapulmonary, with more extensive pulmonary involvement, and with a higher relapse rate.

Catastrophic antiphospholipid syndrome: A case with unusual findings revealed in autopsy and a brief literature update.

Catastrophic antiphospholipid syndrome (CAPS) is a rare and life-threatening disease. It is characterized by multiple arterial and/or venous thrombotic events, including the microcirculation, occurring in a short period, and can affect any system. Catastrophic antiphospholipid syndrome can occur in individuals with known APS under treatment, or it can be its first manifestation; in most cases, there is a triggering factor that can be identified.

Thrombotic events in patients with antiphospholipid syndrome treated with rivaroxaban: a series of eight cases.

The current treatment for antiphospholipid syndrome (APS) with thrombotic manifestation is long-term anticoagulation. Vitamin K antagonists (VKA) are usually the agents of choice. However, VKA limitations, such as unpredictable anticoagulation effects due to interaction with diet and other drugs, require regular monitoring.

14th International Congress on Antiphospholipid Antibodies Task Force Report on Catastrophic Antiphospholipid Syndrome.

The 'Task Force on Catastrophic Antiphospholipid Syndrome (CAPS)' was developed on the occasion of the 14th International Congress on Antiphospholipid Antibodies. The objectives of this Task Force were to assess the current knowledge on pathogenesis, clinical and laboratory features, diagnosis and classification, precipitating factors and treatment of this condition in order to address recommendations for future research. This article summarizes the studies analyzed by the Task Force, its recommendations and the future research agenda.

Prevalence and factors associated with dyslipoproteinemias in Brazilian systemic lupus erythematosus patients.

To determine the prevalence of dyslipoproteinemias and their related factors in a Brazilian systemic lupus erythematosus (SLE) population, fasting lipids were measured in 185 female SLE outpatients. Age, BMI, smoking, post-menopausal status, presence of diabetes and hypertension, SLE duration, number of ARA criteria, drug treatment and disease activity (by SLEDAI) were registered. Statistics included uni and multivariate logistic regression.
