Eur J Obstet Gynecol Reprod Biol X 2024; 24:100340. [PMID: 39296875 PMCID: PMC11405914 DOI: 10.1016/j.eurox.2024.100340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2024] [Revised: 08/26/2024] [Accepted: 08/29/2024] [Indexed: 09/21/2024] Open
Abstract
Background Antiphospholipid Syndrome (APS) is a systemic autoimmune thrombophilic condition characterized by obstetric manifestations, including pregnancy loss, preeclampsia and fetal growth restriction. Early diagnosis and management are key to improve maternal and neonatal outcomes. Objective The aim of this study is to assess the perinatal outcomes in APS, the development of various adverse pregnancy outcomes (APO), and their association with specific antibody profiles. Material methods This observational study was carried out on booked cases of singleton pregnancy and diagnosed cases of primary APS in our High-Risk Pregnancy (HRP) clinic from January 2018 to December 2022 after approval from institutional ethics committee. Forty-three confirmed cases of primary APS were enrolled and started on low-dose aspirin and low-molecular-weight heparin (LMWH) as per the patient's body weight after confirmation of fetal heart activity radiologically until 36 weeks of gestation as a standard of care. Results Forty patients (93 %) had obstetric APS, and three patients (7 %) had thrombotic APS. During the course of the current pregnancy, adverse pregnancy outcomes (APO) developed in 12 (30 %) out of 40 cases of obstetric APS and in all 3 patients with thrombotic APS. Preeclampsia was seen in 11 (25.5 %), FGR in 12 (27.9 %), and preterm birth in 7 (16.2 %) cases. Patients with an antibody profile showing the presence of Anti-β2 GP-I positivity and ACL positivity had fewer APOs (20 % and 29 %) in comparison to patients with a LA and triple positive antibody profile (55 % and 50 %). Conclusion Treatment of pregnant women with APS causes significant improvement in the live birth rate. The late pregnancy complications like preeclampsia, FGR, and premature birth, occurring despite treatment still remains a challenge and emphasizes the need for stringent antepartum surveillance and timely delivery.

Abstract
IMPORTANCE Antiphospholipid syndrome in neonates and children is a rare, but in some cases life-threatening condition with arterial and/or venous thrombosis and/or non-thrombotic neurological, skin, ophthalmological and other manifestations. OBSERVATIONS This review highlights the available information about the features of pediatric APS, including the rare catastrophic form, the differences between pediatric and adult APS, and the role of genetic thrombophilia in APS manifestation. CONCLUSIONS AND RELEVANCE The clinical manifestations and treatment options for APS in children may differ from those in adults, and prescribing therapy can be challenging due to the unique clinical and morphological characteristics of the pediatric patient. Pediatric APS may be a predictor of the development of certain autoimmune diseases and classic manifestations of APS in adulthood, therefore, a revision of the existing criteria for the diagnosis and treatment of APS in children is necessary.

Abstract
Antiphospholipid syndrome (APS) is characterized by hypercoagulability, manifesting as venous or arterial thrombosis, and pregnancy-related complications, such as fetal loss, pre-eclampsia, and eclampsia. These conditions occur in the presence of antiphospholipid antibodies (aPL), including anticardiolipin antibodies (aCL) and/or a positive lupus anticoagulant (LA) test. Antiphospholipid syndrome (APS) can manifest as a primary, isolated condition or be associated with connective tissue diseases, such as systemic lupus erythematosus (SLE). The cardiac system is one of the main target organs affected by APS. This report describes a rare clinical case involving a young woman with a history of recurrent miscarriages, who presented with cardiac complications, including severe mitral regurgitation and Spontaneous coronary artery dissection. Etiological assessment identified antiphospholipid antibody syndrome as the underlying cause. The multidisciplinary management plan included initiating therapeutic-dose anticoagulation, followed by referring the patient for potential mitral valve replacement surgery.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune disease characterized by recurrent arteriovenous thrombosis and pathological pregnancy, accompanied by persistent antiphospholipid antibodies, (aPL). The incidence of APS is increasing year by year, clinicians lack of understanding of this type of disease, easy to misdiagnose and miss the diagnosis. Therefore, it is extremely important to establish a suitable animal model to reduce the process of disease development as much as possible and improve clinicians' understanding and understanding. This review will summarize the animal models of APS from the aspects of modeling methods, modeling mechanism, evaluation indicators and advantages and disadvantages of methods, providing a reference for finding an animal model highly similar to human APS, helping researchers to further clarify the pathogenesis of APS and find potential therapeutic targets, so as to achieve early diagnosis, early intervention, and ultimately improve the prognosis of patients.

Abstract
The heterogeneity of the T cell receptor (TCR) repertoire critically influences the autoimmune response in obstetric antiphospholipid syndrome (OAPS) and is intimately associated with the prophylaxis of autoimmune disorders. Investigating the TCR diversity patterns in patients with OAPS is thus of paramount clinical importance. This investigation procured peripheral blood specimens from 31 individuals with OAPS, 21 patients diagnosed with systemic lupus erythematosus (SLE), and 22 healthy controls (HC), proceeding with TCR repertoire sequencing. Concurrently, adverse pregnancy outcomes in the OAPS cohort were monitored and documented over an 18-month timeframe. We paid particular attention to disparities in V/J gene utilisation and the prevalence of shared clonotypes amongst OAPS patients and the comparative groups. When juxtaposed with observations from healthy controls and SLE patients, immune repertoire sequencing disclosed irregular T- and B-cell profiles and a contraction of diversity within the OAPS group. Marked variances were found in the genomic rearrangements of the V gene, J gene, and V/J combinations. Utilising a specialised TCRβ repertoire, we crafted a predictive model for OAPS classification with robust discriminative capability (AUC = 0.852). Our research unveils alterations in the TCR repertoire among OAPS patients for the first time, positing potential covert autoimmune underpinnings. These findings nominate the TCR repertoire as a prospective peripheral blood biomarker for the clinical diagnosis of OAPS and may offer valuable insights for advancing the understanding of OAPS immunologic mechanisms and prognostic outcomes.

Abstract
BACKGROUND Pediatric arterial ischemic stroke (AIS) is a rare disorder, associated with severe morbidity. In adults, elevated lipoprotein(a) (Lp(a)), a cholesterol-like particle, is associated with ischemic stroke. However, data on Lp(a) and pediatric AIS are scarce. Therefore, we evaluated the association between Lp(a) levels and pediatric AIS. METHODS We included children who suffered an AIS (≤18 years) and were treated in a tertiary center in Amsterdam, the Netherlands. Two groups of children with AIS were identified: (i) neonates and (ii) children older than 29 days. A case-control study was performed, with the latter group as cases and children without AIS as control group. Cases and controls were matched for age of Lp(a) testing and sex. Multivariable logistic regression models were used. RESULTS Thirteen neonates and 23 children were included. Mean (SD) age of AIS was 0.6 (2.0) days and 9.2 (6.3) years, respectively. Children with AIS were matched to 62 controls. Lp(a) levels of greater than 50 mg/dL were more prevalent in children with AIS compared to controls (21.7% vs. 3.2%, p = .02). A significant association was found between Lp(a) and AIS (odds ratio [OR] adjusted for age at Lp(a) testing, body mass index [BMI], measurement assay: 1.36 per 10 mg/dL increase of Lp(a), 95% confidence interval [CI]: 1.02-1.82, p = .041). CONCLUSIONS In this study, Lp(a) levels were positively associated with the risk of AIS in children, suggesting that high Lp(a) might be an independent risk factor for AIS. This underlines the importance of Lp(a) measurement in children with AIS.

Abstract
INTRODUCTION The gut microbiome is recognized as a factor that could potentially contribute to the persistent antibodies of antiphospholipid syndrome (APS). Gut microbial interventions can both induce and mitigate APS in mice. In human APS patients, anti-beta-2-glycoprotein I (β2GP-1) titers correlate with antibody titers against a gut commensal protein homologous to β2GP-1. AIM To investigate the effect of the intestinal microenvironment on human APS. Methods We cross-sectionally compared intestinal microbiota composition quantified by shotgun sequencing; fecal short chain fatty acids (SCFAs), bacterial metabolites known to affect autoimmune processes; and fecal calprotectin, an intestinal inflammatory marker, in APS patients and healthy controls. RESULTS Neither alpha nor beta diversity of the gut microbiota differed between APS patients (n = 15) and controls (n = 16) and no taxa were differentially abundant. Moreover, fecal SCFAs and fecal calprotectin, did not differ between the groups. CONCLUSION Gut microbiome effects on the APS phenotype are likely not driven by bacterial overabundance, SCFA production or intestinal inflammation.

Abstract
INTRODUCTION Systemic Lupus Erythematosus (SLE) is often associated with antiphospholipid syndrome (APS), which manifests as recurrent thrombotic events or obstetric complications in presence of antiphospholipid antibodies. Hereby we present a case of a child who presented with low grade fever, superficial thrombophlebitis with mucosal bleeding and was diagnosed as Lupus Anticoagulant Hypoprothrombonemia Syndrome (LAHS). CASE A 7-year-old girl was hositalized with complaints of fever and spontaneous bleeding from gums and epistaxis. On examination, she had multiple small tender nodular lesions with greenish hue of overlying skin suggesting superficial thrombophlebitis and mild non-tender hepatosplenomegaly. Her coagulogram revealed normal platelet counts and deranged PT and APTT. ESR and CRP were raised. Serology for viral infections, blood and urine cultures were negative. Patient had persistent coagulopathy, mucosal bleeding and low-grade fever despite supportive treatment. She was tested for anti-nuclear antibodies (ANA) in view of suspicion of autoimmune process. ANA was positive in high titer with speckled pattern on indirect immunofluorescence. Mixing studies showed correction of PT and non-correction of APTT. PT based factors were normal except for prothrombin (FII) which was low and remained low despite dilution. APTT based factors (FVIII and FIX) were low but corrected on dilution. This was suggestive of prothrombin deficiency and a presence of a nonspecific inhibitor of APTT pathway (likely lupus anticoagulant). Presence of antiprothrombin antibodies established the diagnosis of LAHS. ENA profile was positive for SmD1, Ro60 and Ku. Complement levels were low. Direct Coomb's test was positive but there was no evidence of hemolysis. Lupus anticoagulant by DRVVT and anti-cardiolipin antibodies by ELISA were positive. Patient was diagnosed as Systemic Lupus Erythematosus with Lupus Anticoagulant Hypoprothrombinemia Syndrome. She was treated with IV methylprednisolone. Patient showed significant improvement in form of resolution of fever, mucosal bleeding, correction of deranged INR and reversal of hypocomplementemia. She was discharged on hydroxychloroquine, mycophenolate mofetil and tapering doses of prednisolone. On follow up, child was doing well and her prothrombin time and complement levels had normalized. Low dose aspirin was aspirin was added for thromboprophylaxis.

Abstract
OBJECTIVE To assess the impact of the updated ACR/EULAR APS classification criteria on two large research cohorts. METHODS Consecutive patients who tested persistently positive for at least one aPL in the last three years were enrolled. The first APS Sydney index event was considered and computed for the comparison between Sydney and 2023 APS criteria. When computing the 2023 APS criteria, additional manifestations were also considered. RESULTS The cohort comprised 249 patients (185 with APS and 64 aPL carriers according to Sydney criteria). The 185 patients had as first index event venous thrombosis in 55 cases (29.8%), arterial thrombosis in 63 (34%) and pregnancy morbidity in 67 (36.2%). When applying the updated criteria, 90 subjects (48.7%) failed to reach the composite score of the new criteria. The percentage of thrombotic APS per Sydney criteria decreased from 47.3% to 34.9% because of high cardiovascular risk in 23 cases, IgM aPL profile in six cases and in two patients for both reasons. Patients with pregnancy morbidity decreased from 26.9% to 3.2% (39 cases of recurrent early pregnancy loss and 20 of fetal losses). Consequently, the percentage of aPL carriers increased from 26% to 61%. When looking at the disease evolution at follow-up, 32 additional patients out of 90 (35.6%) fulfilled the new APS criteria, after developing additional clinical manifestation following index event. CONCLUSION When applying the new APS criteria to our research cohorts, not-negligible differences exist in patients' classification. A multidisciplinary approach will be mandatory to assess the impact of the new criteria on research and, ultimately, patients' care.

Antiphospholipid Antibodies Modify the Prognostic Value of Baseline Platelet Count for Clinical Outcomes After Ischemic Stroke. J Am Heart Assoc 2024; 13:e035183. [PMID: 39344638 DOI: 10.1161/jaha.124.035183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 07/31/2024] [Indexed: 10/01/2024]
Abstract
BACKGROUND Antiphospholipid antibodies (aPLs) have been reported to be involved in platelet-mediated thrombosis and inflammation, but the impact on the prognosis of ischemic stroke remains unclear. We aimed to examine whether the association between baseline platelet count (PLT) and long-term clinical outcomes within 2 years after ischemic stroke onset is modulated by aPLs. METHODS AND RESULTS A total of 2938 patients with ischemic stroke were included in this prospective cohort study. Cox proportional hazards regression models were used to assess the association between the baseline PLT stratified by aPLs status and 2-year clinical outcomes after stroke onset, and an interaction effect between PLT and aPLs on clinical outcomes was tested by likelihood ratio test. There was a significant interaction effect of aPLs and PLT on recurrent stroke (Pinteraction=0.002) and cardiovascular events (Pinteraction=0.001) within 2 years after stroke onset. After multivariate adjustment, high PLT was associated with increased risks of recurrent stroke (hazard ratio [HR], 2.78 [95% CI, 1.03-7.45]; Ptrend=0.039) and cardiovascular events (HR, 2.58 [95% CI, 1.12-5.90]; Ptrend=0.024) when 2 extreme tertiles were compared among patients with aPL positive, but not among those with aPL negative. CONCLUSIONS The aPLs had a modifying effect on the association between PLT and clinical outcomes within 2 years after ischemic stroke onset. Increased PLT was associated with recurrent stroke and cardiovascular events after ischemic stroke onset among patients with aPL positive, but not in those with aPL negative.

Abstract
PURPOSE OF REVIEW This review offers an overview of the most important recent articles on pediatric APS. RECENT FINDINGS Non-thrombotic extra criteria manifestations were prevalent in pediatric APS. Pregnancy morbidity has been described as the first manifestation of APS at youth age, impairing gestational outcomes. The 2023 APS criteria were developed for adult APS patients, and there is still a lack of pediatric-specific APS criteria. Catastrophic APS was more commonly reported as the initial manifestation of pediatric APS than in adults. Regarding treatment, direct oral anticoagulants have been recently approval for pediatric patients with venous thrombosis. New approaches have been proposed for severe cases, for arterial thrombosis, and rituximab for refractory cases. Recurrences typically occurred early and were associated with older age at diagnosis. Current studies highlighted the multifaceted nature of pediatric APS. Further large prospective multicenter studies evaluating new medications capable of reducing recurrence risk and improving prognosis in this population will be required.

Abstract
Fetal death is defined as the spontaneous cessation of cardiac activity after fourteen weeks of amenorrhea. In France, the prevalence of fetal death after 22 weeks is between 3.2 and 4.4/1000 births. Regarding the prevention of fetal death in the general population, it is not recommended to counsel for rest and not to prescribe vitamin A, vitamin D nor micronutrient supplementation for the sole purpose of reducing the risk of fetal death (Weak recommendations; Low quality of evidence). It is not recommended to prescribe aspirin (Weak recommendation; Very low quality of evidence). It is recommended to offer vaccination against influenza in epidemic periods and against SARS-CoV-2 (Strong recommendations; Low quality of evidence). It is not recommended to systematically look for nuchal cord encirclements during prenatal screening ultrasounds (Strong Recommendation; Low Quality of Evidence) and not to perform systematic antepartum monitoring by cardiotocography (Weak Recommendation; Very Low Quality of Evidence). It is not recommended to ask women to perform an active fetal movement count to reduce the risk of fetal death (Strong Recommendation; High Quality of Evidence). Regarding evaluation in the event of fetal death, it is suggested that an external fetal examination be systematically offered (Expert opinion). It is recommended that a fetopathological and anatomopathological examination of the placenta be carried out to participate in cause identification (Strong Recommendation. Moderate quality of evidence). It is recommended that chromosomal analysis by microarray testing be performed rather than conventional karyotype, in order to be able to identify a potentially causal anomaly more frequently (Strong Recommendation, moderate quality of evidence); to this end, it is suggested that postnatal sampling of the placental fetal surface for genetic purposes be preferred (Expert Opinion). It is suggested to test for antiphospholipid antibodies and systematically perform a Kleihauer test and a test for irregular agglutinins (Expert opinion). It is suggested to offer a summary consultation, with the aim of assessing the physical and psychological status of the parents, reporting the results, discussing the cause and providing information on monitoring for a subsequent pregnancy (Expert opinion). Regarding announcement and support, it is suggested to announce fetal death without ambiguity, using simple words and adapting to each situation, and then to support couples with empathy in the various stages of their care (Expert opinion). Regarding management, it is suggested that, in the absence of a situation at risk of disseminated intravascular coagulation or maternal vitality, the patient's wishes should be taken into account when determining the time between the diagnosis of fetal death and induction of birth. Returning home is possible if it's the patient wish (Expert opinion). In all situations excluding maternal life-threatening emergencies, the preferred mode of delivery is vaginal delivery, regardless the history of cesarean section(s) history (Expert opinion). In the event of fetal death, it is recommended that mifepristone 200mg be prescribed at least 24hours before induction, to reduce the delay between induction and delivery (Low recommendation. Low quality of evidence). There are insufficient data in the literature to make a recommendation regarding the route of administration (vaginal or oral) of misoprostol, neither the type of prostaglandin to reduce induction-delivery time or maternal morbidity. It is suggested that perimedullary analgesia be introduced at the start of induction if the patient asks, regardless of gestational age. It is suggested to prescribe cabergoline immediately in the postpartum period in order to avoid lactation, whatever the gestational age, after discussing the side effects of the treatment with the patient (Expert opinion). The risk of recurrence of fetal death after unexplained fetal death does not appear to be increased in subsequent pregnancies, and data from the literature are insufficient to make a recommendation on the prescription of aspirin. In the event of a history of fetal death due to vascular issues, low-dose aspirin is recommended to reduce perinatal morbidity, and should not be combined with heparin therapy (Low recommendation, very low quality of evidence). It is suggested not to recommend an optimal delay before initiating another pregnancy just because of the history of fetal death. It is suggested that the woman and co-parent be informed of the possibility of psychological support. Fetal heart rate monitoring is not indicated solely because of a history of fetal death. It is suggested that delivery not be systematically induced. However, induction can be considered depending on the context and parental request. The gestational age will be discussed, taking into account the benefits and risks, especially before 39 weeks. If a cause of fetal death is identified, management will be adapted on a case-by-case basis (expert opinion). In the event of fetal death occurring in a twin pregnancy, it is suggested that the surviving twin be evaluated as soon as the diagnosis of fetal death is made. In the case of dichorionic pregnancy, it is suggested to offer ultrasound monitoring on a monthly basis. It is suggested not to deliver prematurely following fetal death of a twin. If fetal death occurs in a monochorionic twin pregnancy, it is suggested to contact the referral competence center, in order to urgently look for signs of acute fetal anemia on ultrasound in the surviving twin, and to carry out weekly ultrasound monitoring for the first month. It is suggested not to induce birth immediately.

Abstract
INTRODUCTION Patients with Antiphospholipid Syndrome (APS) undergoing cardiopulmonary bypass (CPB) surgery are at increased risk for thrombotic and hemorrhagic complications. Anticoagulation during CPB is typically monitored with activated clotting time (ACT) which may be falsely prolonged in patients with APS. The Hepcon Hemostasis Management System quantitatively determines the whole blood heparin concentration through heparin/protamine titration. METHODS This was a retrospective study of APS patients who underwent cardiac surgery requiring CPB at the Cleveland Clinic between April 2013, and July 2020. The primary endpoint was the composite rate of hemorrhagic or thromboembolic complications per surgical case in patients monitored by Hepcon versus patients monitored by ACT. Secondary endpoints were median volume of chest tube output and packed red blood cell (PRBC) transfusion within the first three post-operative days. RESULTS 43 patients were included. 20 (47%) patients were monitored using Hepcon while 23 (53%) were monitored using ACT. For the primary endpoint of rate of thromboembolic or hemorrhagic complications per surgical case, there was no statistically significant difference between the Hepcon and ACT groups (HMS, 6/20 [30%]; ACT, 7/23 [30%]; p = >0.99). For the secondary endpoints, there was no statistically significant difference in median post-operative chest tube output (780 mL vs. 850 mL; p = 0.88) and median post-operative PRBC transfusion (1 unit vs. 0 unit; p = 0.28) between the Hepcon and ACT groups, respectively. CONCLUSION There was no difference in the composite outcome of thrombotic or hemorrhagic complications in patients monitored by Hepcon versus those monitored by ACT.

Abstract
BACKGROUND Antiphospholipid antibodies (aPL), including lupus anticoagulant, antibodies against β2 glycoprotein I (anti-β2GPI), and anticardiolipin (aCL) antibodies are associated with ischemic stroke (IS). Their prevalence and clinical relevance in atrial fibrillation (AF) remain unclear. OBJECTIVES To assess whether aPL are associated with increased risk of IS in AF patients despite anticoagulation. METHODS We conducted a post hoc analysis of aPL using blood samples from 243 consecutive AF patients enrolled in a cohort study. Markers of a prothrombotic state, including endogenous thrombin potential, fibrin clot permeability, and lysis time, were measured at baseline. During a median follow-up of 52 months, IS/transient ischemic attack and major bleeding were recorded. RESULTS We observed aPL at a moderate or high titer in 51 (21%) patients, including 17 (7%) with anti-β2GPI, 19 (7.8%) with aCL antibodies, and 37 (15.2%) with lupus anticoagulant. aPL-positive patients were more likely to have prior stroke (P = .01) and be active smokers (P = .03), along with increased endogenous thrombin potential (P = .02), without any changes in fibrin clot properties. Anti-β2GPI (hazard ratio, 4.38; 95% CI, 1.58-12.19) and aCL (hazard ratio, 4.70; 95% CI, 1.80-12.30) at a moderate or high titer were associated with IS during follow-up (n = 20; 1.9% per year). There were 23 major bleedings (2.1% per year) and 20 deaths (1.9% per year), which were not associated with aPLs. CONCLUSION Our study showed a relatively high prevalence of aPL positivity in AF patients, which was linked to an increased risk of IS/transient ischemic attack. This suggests that screening for aPL might help optimize anticoagulant therapy in such patients.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by the presence of antiphospholipid antibodies (aPLA), such as anticardiolipin (aCL), anti-β2-glycoprotein I (aβ2GPI), or lupus anticoagulant (LA). Although cerebrovascular events are commonly associated with APS, comprehensive studies on risk factors for cerebral infarction in aPLA-positive patients remain sparse. In this retrospective single-center study, data from 9844 patients tested for aPLA between January 2017 and March 2023 were analyzed. A total of 647 aPLA-positive patients were included, with assessments of various factors including age, gender, hypertension, diabetes, dyslipidemia, smoking history, and cardiac disease. Propensity score matching was employed to create 2 matched groups of 202 patients each, comparing those with and without cerebral infarction. Logistic regression analyses were conducted to identify risk factors for cerebral infarction and progression of cerebrovascular stenosis. The mean age of the study cohort was 65.8 years, with 60% being male. LA was positive in 95.2% of the cases, aCL in 8.8%, and aβ2GPI in 5.3%. High-risk aPLA profiles were identified in 7.1% of the cases. In the cerebral infarction group, both smoking history and aCL positivity were significantly associated with an increased risk (OR = 1.543; 95% CI: 1.020-2.334; P = .040 and OR = 3.043; 95% CI: 1.426-6.491; P = .040, respectively). Male gender and posterior circulation involvement were significant risk factors for exacerbation of cerebrovascular stenosis (OR = 3.73; 95% CI: 1.16-16.69; P = .046 and OR = 5.41; 95% CI: 1.80-16.05; P = .002, respectively). Smoking history and aCL positivity are prominent risk factors for cerebral infarction in aPLA-positive patients, while male gender and involvement of the posterior circulation emerge as significant risk factors for the progression of cerebrovascular stenosis. Further comprehensive prospective studies are necessary to deepen understanding of aPLA-related cerebrovascular diseases.

Abstract
BACKGROUND Antiphospholipid syndrome (APS) is an acquired autoimmune disorder characterized by distinct pathophysiological mechanisms leading to heterogeneous manifestations, including venous and arterial thrombosis. Despite the lack of specific markers of thrombosis risk in APS, some of the mechanisms responsible for thrombosis in APS may overlap with those of other thromboembolic diseases. Understanding these similarities is important for improving the assessment of thrombosis risk in APS. MicroRNAs (MiRNAs) are RNA molecules that regulate gene expression and may influence the autoimmune response and coagulation. PURPOSE In this scoping review we aimed to investigate shared miRNAs profiles associated with APS and other thromboembolic diseases as a means of identifying markers indicative of a pro-thrombotic profile among patients with APS. DATA COLLECTION AND RESULTS Through a comprehensive search of scientific databases, 45 relevant studies were identified out of 1020 references. miRs-124-3p, 125b-5p, 125a-5p, and 17-5p, were associated with APS and arterial thrombosis, while miRs-106a-5p, 146b-5p, 15a-5p, 222-3p, and 451a were associated with APS and venous thrombosis. Additionally, miR-126a-3p was associated with APS and both arterial and venous thrombosis. CONCLUSION We observed that APS shares a common miRNAs signature with non-APS related thrombosis, suggesting that miRNA expression profiles may serve as markers of thrombotic risk in APS. Further validation of a pro-thrombotic miRNA signature in APS is warranted to improve risk assessment, diagnosis, and management of APS.

Abstract
OBJECTIVE Patients with systemic lupus erythematosus (SLE) have an increased risk of cardiovascular and cerebrovascular events (CCEs). Furthermore, CCE was a significant factor contributing to mortality in patients with SLE. However, no clinical model exists that can predict which patients are at high risk. The purpose of this study was to develop a practical model for predicting the risk of CCE in people with SLE. METHODS This study was based on the Chinese SLE Treatment and Research Group cohort. A total of 2399 patients, who had a follow-up period of over 3 years and were diagnosed with SLE for less than 1 year at the start of the study, were included. Cox proportional hazards regression and least absolute shrinkage and selection operator regression were used to establish the model. Internal validation was performed, and the predictive power of the model was evaluated. RESULTS During the follow-up period, 93 patients had CCEs. The prediction model included nine variables: male gender, smoking, hypertension, age of SLE onset >40, cutaneous involvement, arthritis, anti-β2GP1 antibody positivity, high-dose glucocorticoids and hydroxychloroquine usage. The model's C index was 0.801. Patients with a prognostic index over 0.544 were classified into the high-risk group. CONCLUSION We have developed a predictive model that uses clinical indicators to assess the probability of CCE in patients diagnosed with SLE. This model has the ability to precisely predict the risk of CCE in patients with SLE. We recommended using this model in the routine assessment of patients with SLE.

Abstract
BACKGROUND The efficacy and safety of direct oral anticoagulants (DOACs) versus warfarin in patients with antiphospholipid syndrome-associated venous thromboembolism (APS-VTE) remain uncertain. We aimed to evaluate efficacy and safety of DOACs in patients with APS-VTE. METHODS Using the Korean Health Insurance Review and Assessment Service database, we retrospectively identified all APS-VTE cases. We examined the VTE recurrence, arterial thrombosis, death and bleeding in patients who received DOACs compared with warfarin for therapeutic anticoagulation. RESULTS Of all the VTE cases (n = 84,916) detected between 2014 and 2018, patients with APS-VTE (n = 410) accounted for 0.48%. Most patients with APS-VTE (73%) were aged < 60 years. The recurrent VTE occurred in 8 of 209 patients (3.8%) who received DOACs and in 7 of 201 (3.5%) who received warfarin (relative risk [RR], 1.099; 95% confidence interval [CI], 0.41-2.98; P = 1.000). The arterial thrombosis (ATE) occurred in 8 of 209 patients (3.8%) who received DOAC and in 20 of 201 (10%) who received warfarin (RR, 0.385; 95% CI, 0.17-0.85; P = 0.024). The composite outcomes of VTE recurrence, ATE, or mortality were significantly lower in patients (9.1%) on DOAC than in those (16.3%) on warfarin (RR, 0.537; 95% CI, 0.32-0.91; P = 0.028). The bleeding outcome occurred in 7 of 209 (3.4%) patients in the DOACs group and 7 of 201 (3.5%) patients in the warfarin group (RR, 0.96; 95% CI, 0.34-2.69; P = 0.840). CONCLUSION In patients with APS-VTE, DOACs group showed comparable rates of recurrent VTE, bleeding, and deaths, but a significantly lower incidence of ATE and composite outcomes compared with the warfarin group in Korea.

Abstract
Patients with thrombotic antiphospholipid syndrome (APS) are at high risk for recurrent thrombosis, and indefinite anticoagulation is recommended. Patients with APS merit indefinite anticoagulation, and vitamin K antagonists (VKAs) have historically been the standard treatment. Direct oral anticoagulants (DOACs) present an appealing alternative to VKAs. Due to their pharmacokinetic and pharmacodynamic characteristics, DOACs offer advantages over VKAs, namely the lack of need for laboratory monitoring, the usage of a fixed dosage, and the absence of significant interaction with dietary components and drugs. The efficacy and safety of DOACs in patients with APS have been studied in four phase II/III clinical trials (three with rivaroxaban and one with apixaban). These studies showed DOACs' inferiority compared to VKAs in preventing recurrent thrombosis. Recurrence was significantly greater in patients with arterial thrombotic events and a triple positivity for antiphospholipid antibodies. No differences were observed in the incidence of venous thromboembolism between both groups. Major bleeding was similar in patients treated with DOACs or VKAs. Several observational studies have reported similar results. This review aims to analyse the existing evidence on the efficacy and safety of DOACs for secondary prevention in patients with APS.

Abstract
OBJECTIVES This study aims to evaluate the utility of the 2023 ACR/EULAR antiphospholipid syndrome (APS) classification criteria in identifying primary APS patients at high risk of complications. METHODS In this single-center study, primary APS patients were classified according to both the revised Sapporo criteria and the 2023 ACR/EULAR criteria. The risk of complications was assessed using the adjusted Global Antiphospholipid Syndrome Score (aGAPSS). RESULTS Forty-five patients (73% females, median age 49 years) were included. Thirty-six patients met the 2023 ACR/EULAR criteria, all of whom also fulfilled the revised Sapporo criteria. Additionally, four out of nine patients not meeting the 2023 ACR/EULAR criteria satisfied the revised Sapporo criteria. Agreement rate between the two classification criteria was 91%, with a Cohen's kappa index of 0.66. Patients meeting the 2023 ACR/EULAR criteria had significantly higher aGAPSS scores compared to those who did not (13, 8-13 vs. 3, 0-5; p = 0.005). Furthermore, 55% of patients meeting the 2023 ACR/EULAR criteria were categorized as high risk based on aGAPSS scores, while those not meeting the criteria were predominantly categorized as low risk (77%). Interestingly, patients not meeting the 2023 ACR/EULAR criteria but fulfilling the revised Sapporo criteria had significantly higher aGAPSS scores compared to those not meeting either set of criteria (7, 5-13 vs. 0, 0-1.5; p = 0.015). CONCLUSION The 2023 ACR/EULAR criteria effectively identify primary APS patients at increased risk of complications, as indicated by the aGAPSS score. Key Points • Identifying primary APS patients at high risk of complications remains a significant challenge. • The 2023 ACR/EULAR criteria show a correlation with the aGAPSS score, exhibiting the highest correlation with laboratory domains and minimal correlation with clinical domains. • The 2023 ACR/EULAR classification criteria are effective in identifying primary APS patients at high risk of complications.

Abstract
Background/Objectives: Lupus nephritis (LN) is one of the most severe organ manifestations of systemic lupus erythematosus (SLE). The aim of our retrospective cohort study was to compare the clinical characteristics, therapy, survival, causes of death, and prognostic factors of LN and non-LN lupus patients. Moreover, we compared a wide spectrum of clinical data of LN patients diagnosed before and since 2005 to determine any changes in disease course and outcomes. Methods: We assessed the clinical and laboratory data of 384 SLE patients, out of whom, 127 patients were diagnosed with LN between 1990 and 2020. Results: Based on our observations, discoid LE, subacute cutaneous LE, antiphospholipid syndrome, Sjögren's syndrome, and rheumatoid arthritis were more common in non-LN patients, while anemia and anti-RNP positivity were more frequent in LN patients. Development of LN did not affect survival rates; male sex and presence of APS were negative prognostic parameters in the non-LN group while achieving remission was a positive prognostic factor in both groups. Death caused by sepsis was more prevalent in the LN group. Serositis and neurological manifestations occurred less frequently in LN patients diagnosed after 2005. The use of mycophenolate mofetil became more common, and the cumulative corticosteroid dose decreased. The SLICC Damage Index score also decreased. Conclusions: Our study demonstrated that the disease course has changed in recent years, and the main therapeutic goal in both SLE and lupus nephritis should be to achieve remission because this significantly improves long-term prognosis and patient survival.

Abstract
The objective of this study was to analyze complement activation in antiphospholipid antibody (aPL)-positive patients without other systemic autoimmune rheumatic diseases, using C3/C4 and cell-bound complement activation products (CB-CAPs) (B-lymphocytes [BC4d], erythrocytes [EC4d], and platelets [PC4d]). Persistently aPL-positive patients with or without aPL-related clinical manifestations (thrombotic APS [TAPS], microvascular APS [MAPS], obstetric APS, thrombocytopenia [TP], and/or hemolytic anemia [HA]) were enrolled in a single center study. Blood and clinical data were collected at baseline; a subgroup of patients completed 6- or 12-month follow-up. At baseline, 4/31 (13%) patients had decreased C3/C4, while 7/29 (24%) had elevated BC4d, 11/33 (33%) EC4d, and 12/32 (38%) PC4d. Based on different aPL profiles, all patients with decreased C3/C4 or elevated BC4d, EC4d, and PC4d had triple aPL or isolated lupus anticoagulant positivity. Based on different aPL clinical phenotypes, the number of patients with strongly positive EC4d and PC4d were proportionally higher in those with MAPS/TP/HA, compared to TAPS or no APS. Compared to baseline, the frequencies of BC4d, EC4d, and PC4d positivity were not significantly different in the subgroup of patients during their 6- or 12-month follow-up. There was a weak correlation between C3/C4 and CB-CAPs, especially for PC4d. In summary, complement activation in aPL-positive patients varies based on aPL profiles and clinical phenotypes. Given the higher percentage of aPL-positive patients with abnormal CB-CAPs, compared to C3/C4, and the poor inverse correlation between CB-CAPs and C3/C4, our study generates the hypothesis that CB-CAPs have a role in assessing disease activity and thrombosis risk in aPL-positive patients.

Abstract
BACKGROUND Ovulation induction for in vitro fertilization (IVF) may increase intravascular thromboses among patients with antiphospholipid autoantibodies (aPLs) or antiphospholipid syndrome (APS) due to the high estrogen levels. While natural or modified natural IVF treatment cycles (MNC) are sometimes used instead of stimulated cycles with empiric anticoagulant treatment among these infertile patients, their efficacy is unclear. MATERIALS AND METHODS A retrospective cohort study including all IVF cycles of patients diagnosed with aPLs or APS in a tertiary, university-affiliated hospital between 2012 and 2022. The outcomes of stimulated cycles with anticoagulants and MNC and natural IVF cycle attempts were compared. RESULTS 121 oocyte retrievals from 38 women were analyzed: 93 stimulated and 28 MNC or natural IVF cycles. The rates of cycle cancellation (0 % vs. 17.9 %, p < 0.001) and cycles in which no oocytes were retrieved (0 % vs. 43.5 %, p < 0.001) were significantly lower following stimulated cycles vs. natural and MNC. In parallel, positive β-hCG (31.9 % vs. 10.9 %, p = 0.03), clinical pregnancy rate (23.6 % and 3.6 %, p < 0.001) and live birth rates (18.1 % vs. 3.6 %, p = 0.01) were significantly higher following stimulated cycles. No thrombotic events or bleeding occurred in any cycle. CONCLUSION Ovarian stimulation for IVF is more effective for successful pregnancy and delivery than natural cycles and MNC and can be safely undertaken in aPLs or APS women undergoing IVF. Rates of complication from hormonal treatment are not increased when treated with LMWH during ovarian stimulation.

Abstract
Hypercoagulable states, also called thrombophilia, can either be congenital or acquired. Congenital thrombophilia, associated mainly with venous thrombosis, is either secondary to coagulation-inhibitor deficiencies, i.e., antithrombin, protein C and Protein S, or gain of function mutations, i.e., factor V Leiden and prothrombin G20210A mutations. Despite the relative frequency of these two mutations, they have not been associated with venous thrombosis recurrence. Most prevalent thrombophilia have a limited impact and usually does not change indications for duration of antithrombotic treatment or prophylaxis compared to decisions based on clinical factors. However, rare inherited thrombophilia such as antithrombin deficiency could justify a long-term anticoagulation. The main acquired thrombophilia, the Antiphospholipid syndrome (APS), is associated with both arterial and venous thrombosis. Its impact on patient management is significant: choice of the anticoagulant (DOAC vs. warfarin), duration of anticoagulation, screening of any organ involvement and systemic autoimmune disease, introduction of immunosuppressive therapy.

Sci Rep 2024; 14:20529. [PMID: 39227704 PMCID: PMC11371915 DOI: 10.1038/s41598-024-71549-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Accepted: 08/28/2024] [Indexed: 09/05/2024] Open
Abstract
Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by vascular thrombosis and obstetric morbidity, with accurate laboratory examination of antiphospholipid antibodies (aPLs) being crucial for diagnosis. This study focused on anti-β2 glycoprotein I (aβ2GPI) antibodies and aimed to establish the first population-based cutoff values for aβ2GPI IgA/IgM/IgG antibodies in non-pregnant women of reproductive age in Southwest China. The study cohort comprised 181 healthy women of reproductive age for study. Blood samples were collected on an early morning fast. Anti-β2GPI antibodies including IgA, IgM and IgG were measured in serum using the HOB® BioCLIA kit. According to the Clinical and Laboratory Standards Institute (CLSI) guidelines, the study used non-parametric percentile methods to calculate the 95th, 97.5th, and 99th percentiles cutoff values for aβ2GPI IgA/IgM/IgG antibodies, along with corresponding 90% confidence intervals (CI), while excluding outliers. A total of 168 independent samples were collected for verification, including 85 samples from healthy subjects and 83 samples from APS patients, in order to evaluate the analytical performance of the obtained cutoff values. The 99th percentile cutoff values were 3.36 RU/mL for aβ2GPI IgA, 27.54 RU/mL for aβ2GPI IgM and 1.81 RU/mL for aβ2GPI IgG, which indicated that the levels of aβ2GPI IgM antibodies were generally higher compared to those of IgA and IgG antibodies. Our established reference range was confirmed to be successful in validating the detected values of aβ2GPI antibodies in all healthy controls. With the 99th percentile cutoff value, the sensitivity was 14.46% for aβ2GPI IgA, 22.89% for aβ2GPI IgG, and 9.64% for aβ2GPI IgM in APS patients. This study established population-based cutoff values that are applicable to the local population for the accurate laboratory examination of aβ2GPI antibodies in non-pregnant women of reproductive age. The study also recommends paying more attention to IgM positivity in women of reproductive age.

Criteria and non-criteria antiphospholipid autoantibodies screening in patients with late pregnancy morbidity: A cross-sectional study. Placenta 2024; 154:122-128. [PMID: 38959700 DOI: 10.1016/j.placenta.2024.06.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 05/20/2024] [Accepted: 06/28/2024] [Indexed: 07/05/2024]
Abstract
INTRODUCTION Antiphospholipid syndrome (APS) is a cause of pregnancy morbidity. We aim to determine the frequency of criteria and non-criteria anti-phospholipid (aPL) autoantibodies in patients admitted for unexplained fetal death (UFD), pre-eclampsia (PE) and/or fetal growth restriction (FGR). METHODS All consecutive patients with UFD, PE and/or FGR followed in the department of Obstetrics, Bichat Hospital, University of Paris, Paris, between January 2019 and December 2021 were screened. Patients with available serum stored from the index pregnancy were included. Patients with previously known APS or twin pregnancy were excluded. Testing for aPL autoantibodies included anti-cardiolipin (aCL), anti-β2GPI (aβ2GPI), anti-phosphatidylethanolamine (aPE), anti-phosphatidylserine/prothrombin (aPS/PT) IgG/IgM and anti-annexin V IgG. When available, placenta specimens were analyzed by a pathologist blinded to the aPL status. All clinical characteristics, pregnancy features, and comorbidities were extracted from electronic medical records. RESULTS Overall 167 (32 (28.8-35.7) years) patients with UFD (n = 28; 16.8 %), PE (n = 60; 35.9 %) and/or FGR (n = 105; 62.9 %) were screened for aPL autoantibodies. Moderate titers of aPL autoantibodies were detected in 33 (n = 33/167, 19.8 %) patients. aPL autoantibodies were non-criteria aPE IgG/IgM in most cases (n = 28/33, 84.8 %). aPS/PT IgG/IgM were found in 11 (n = 11/33, 33.3 %) cases and aCL or aβ2GP1 IgG/IgM in 4 (n = 4/33, 12.1 %). Multivariable logistic regression showed that aPL autoantibodies were mostly associated with UFD (OR 4.37 [1.72-11.20], p = 0.002), PE ≤ 34th week of gestation (3.22 [0.86-11.90], p = 0.070) and chronic deciduitis (8.03 [0.89-67.2], p = 0.060) DISCUSSION: The frequency of aPL autoantibodies, mostly aPE, is high in patients with late pregnancy morbidity and may qualify obstetrical APS.

Abstract
Psychiatric disorders are reported to be associated with systemic inflammatory conditions and autoimmune diseases. Antiphospholipid syndrome (APS) is a rare condition with poorly understood prevalence and incidence in the general population. Case reports have described co-occurrences of psychiatric conditions and APS. Previous case reports have indicated that patients with APS can have comorbid psychosis, anxiety, depression, and other psychiatric conditions. The association between APS and psychiatric illness, however, remains under-investigated in longitudinal studies. In this report, we present the case of a woman in her 40s who was voluntarily admitted to the psychiatric inpatient unit for treatment of auditory hallucinations within the context of borderline personality disorder. She reported a rather extensive medical and psychiatric history of several previous illnesses, musculoskeletal injuries, and hospitalizations. Due to the significant social stress and multiple comorbidities, she may be at increased vulnerability to acute exacerbations of both APS and brief psychotic episodes. In this case report, the patient had a history of three hypercoagulability incidents that were shortly followed by psychiatric admissions. This report highlights the importance of considering systemic conditions such as APS in patients presenting with psychiatric illness. Patients with APS and concomitant psychosis may benefit from screening for APS flares in the case of a psychotic break.

Abstract
INTRODUCTION Despite thromboprophylaxis, women with antiphospholipid syndrome (APS) face high-risk pregnancies due to proinflammatory and prothrombotic states. This highlights the need for new monitoring and prognostic tools. Recent insights into the pathophysiological role of neutrophil activation and extracellular trap (NET) formation in this syndrome led to the exploration of plasma cell-free DNA (cfDNA), a derivative of NETosis, as a promising biomarker. MATERIALS AND METHODS cfDNA was isolated and quantified from plasma samples of healthy pregnant women (control group, HC) and women with APS (APS group). We assessed the physiological variability of cfDNA across the three trimesters in HC. Levels of cfDNA were compared between APS and HC by gestational trimester. ROC curve analysis was performed to evaluate the efficacy of cfDNA levels for classifying APS patients. Furthermore, cfDNA levels in pregnant women with APS with obstetric complications were compared to those from uncomplicated pregnancies. RESULTS Among HC, cfDNA significantly increased in the third trimester compared to the first and second. Elevated cfDNA levels in APS compared to HC were observed in the first and second trimesters. First-trimester cfDNA levels demonstrated the highest classification ability to discriminate between APS and HC patients (AUC: 0.906). Among APS, those with complicated pregnancies (fetal growth restriction, preeclampsia, placenta accreta) exhibited significantly elevated cfDNA levels in the second trimester. CONCLUSIONS Elevated levels of cfDNA in pregnant women with APS, particularly among those with obstetric complications, supports further investigation into the potential of cfDNA as a valuable tool in the obstetric management of women with APS.

Abstract
OBJECTIVE Antiphospholipid syndrome (APS) is an autoimmune disease mainly affecting young individuals. Testing for antiphospholipid antibodies is recommended for young patients who are suspected to have APS. Yet, it is hard to differentiate APS from other acquired thrombophilia disorders in elderly-onset APS patients. This study aim to investigate the characteristics and prognosis of elderly-onset APS. METHODS This is an observational cohort study. Thrombotic APS patients who underwent follow-ups between 2009 and 2022 were included. Elderly-onset APS patients (onset age ≥60 years) were compared to non-elderly-onset APS patients (onset age <60 years) and matched cases of elderly non-APS patients (age ≥60 years with thrombosis). RESULTS A total of 161 APS patients were included in this study, 45 (28.0%) were elderly-onset APS. Stroke (35.6% vs. 18.1%, p = .018) was more common at disease onset in elderly-onset APS patients. Compared to non-elderly-onset patients, elderly-onset APS patients were associated with a higher number of cardiovascular risk factors. Elderly-onset APS patients showed significantly lower positive rate (51.1% vs. 71.6%, p = .014) and ratios [1.24 (1.01-1.38) vs. 1.37 (1.16-1.77), p = .004] of lupus anticoagulant. Elderly-onset APS patients had a significantly higher 10-years cumulative all-cause mortality (p < .001) and APS-related mortality than non-elderly-onset patients (p = .002) and elderly non-APS patients (p = .040). CONCLUSIONS Elderly-onset APS patients have unique disease characteristics with higher 10-years cumulative all-cause mortality and APS-related mortality. Early recognition and control of comorbidities may reduce the recurrence of thrombosis and mortality in elderly-onset APS patients.

Abstract
Classification criteria of autoimmune rheumatic diseases are an important means to define homogenous groups of patients that can be compared across studies for clinical trials and research purposes. The measurement of autoantibodies is a relevant aspect in the definition of classification criteria, with a significant weight in the scores necessary to classify patients with autoimmune rheumatic diseases. The impact of autoantibodies has gradually increased over the years, contributing to the evolution and improvement of the classification criteria. However, these criteria often do not take into consideration how autoantibodies are measured, i.e. differences in diagnostic accuracy of the methods. This is a critical point especially when obsolete analytical methods that are no longer used in many clinical laboratories are taken into consideration. In this review we have critically examined assays and methods for the determination of autoantibodies that are (or could be) included among the classification criteria of autoimmune rheumatic diseases in light of more recent evidence and technology evolution.

Abstract
OBJECTIVES Severe thrombotic antiphospholipid syndrome (APS) frequently affects the kidney, heart, and central nervous system. The precise frequency, clinical picture, differential diagnoses, and outcome of APS-related hematological involvement are lacking, especially in patients requiring ICU admission. This study aimed to describe the hematological manifestations associated with critically ill thrombotic APS patients and catastrophic antiphospholipid syndrome. METHODS This French, national, multicenter, retrospective study, conducted, from January 2000 to September 2018, included all APS patients admitted to 24 participating centers' ICUs with any new thrombotic manifestation. The prevalence of hematological manifestations and their associated outcomes were studied. RESULTS One hundred and thirty-four patients, female 72%, median [IQR] age 45 [34-56] years, with 152 episodes were included. Anemia was present in 95% of episodes and thrombocytopenia in 93%. The lowest values for hemoglobin and platelets were 7.1 [6.3-8.8] g/dL and 38 [21-60] g/L, respectively. The lowest platelet count below 20 g/L was significantly associated with a higher in-ICU mortality rate (50%, p < 0.0001). A thrombotic microangiopathy syndrome (TMA) syndrome was seen in 16 patients (12%) and was associated with higher in-hospital mortality (p = 0.05). Median ADAMTS-13 levels were 44% [27-74]. Anti-ADAMTS13 antibodies were tested in 11 patients and found negative in all. A suspicion of heparin-induced thrombocytopenia (HIT) was raised in 66 patients but only four patients were classified as definite HIT. Disseminated intravascular coagulation (DIC) was seen in 51% of patients. CONCLUSION Thrombocytopenia is very frequent in severe APS patients and may be related to TMA, HIT, or DIC. Deciphering the mechanisms of thrombocytopenia is decisive in CAPS patients. Key Points • Thrombocytopenia is the hallmark laboratory finding in CAPS. • A complete thrombotic microangiopathy pattern is infrequent in CAPS patients. • Alternate diagnoses of CAPS, especially heparin-induced thrombocytopenia, need to be adequately investigated.

Abstract
The spectrum of pediatric rheumatological disorders is diverse and they are important differential diagnoses in a variety of clinical scenarios. Basic investigations not only provide supporting evidence for the diagnosis of a rheumatological illness but also help in exclusion of other diseases as well as for monitoring the activity of disease. Among these, complete blood count, biochemical assays including tests for inflammatory response, urine analysis, and various autoantibodies are often used. In addition, depending on the clinical features, imaging and tissue biopsies are used to confirm the diagnosis.

Abstract
The standard hemostasis workup [quick time (QT), and activated partial thrombin time (APTT)] is very commonly prescribed but its interpretation is often difficult for practitioners who are not specialized in hemostasis. Here, we review the principles of the diagnostic approach to these tests. Only a very basic knowledge of the coagulation cascade is necessary to identify which clotting factor tests to prescribe and to interpret the results. Deficiency in several clotting factors suggests liver dysfunction, disseminated intravascular coagulation (DIC) or vitamin K deficiency. If a single factor is deficient, we review the different causes of acquired deficiencies and briefly discuss the characteristics of the different congenital defects, which generally require specialized management. Lupus anticoagulant is a common and generally benign cause of prolonged APTT to be aware of, which is not related to a hemorrhagic risk. A good knowledge of the diagnostic approach to abnormal QT or APTT generally allows the resolution of the most common situations.

Abstract
Antiphospholipid syndrome (APS) in children is a rare disease associated with significant morbidity and mortality. In comparison with APS in adults, pediatric APS has a more severe presentation with frequent recurrences of thrombotic events and a higher probability of life-threatening catastrophic APS. Nonthrombotic manifestations are also more common in the pediatric age group and can precede thrombosis. New classification criteria have been introduced recently and have not yet been assessed in pediatric patients with APS. In addition to anticoagulation drugs, other novel therapies have emerged including the use of B cell and complement inhibitors, especially in catastrophic APS. The purpose of this review is to provide a broad overview of aPL-related clinical manifestations in pediatric patients based on the analysis of published cohorts and data from the international pediatric APS registry. We also aim to illustrate APS in infants caused by transplacentally transferred maternal aPL, which is very rarely associated with acute thrombotic events in the perinatal period and more frequently with long-term neurodevelopmental abnormalities.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune disorder that presents with hypercoagulability and results in a lab artifact of prolonged PTT. The most severe form is catastrophic antiphospholipid antibody syndrome (CAPS), which manifests as rapidly progressing thromboses in multiple organ systems leading to multi-organ ischemia. The mainstay management CAPS is anticoagulation and systemic corticosteroids. Antifibrinolytic agents have previously been thought to be relatively contraindicated in CAPS due to the pro-thrombotic nature of the disease; the complex coagulation profile of CAPS can make it difficult to assess the risks and benefits of antifibrinolytic therapy. Also, should a patient with CAPS require cardiopulmonary bypass (CPB) for surgery, it poses a unique challenge in providing appropriate anticoagulation in the setting of prolonged ACT. We present a case of a 32-year-old postpartum female with CAPS requiring heart transplant who safely received intraoperative antifibrinolytic therapy and was successfully anticoagulated during CPB after perioperative plasmapheresis.

Abstract
The term 'routine coagulation' typically applies to hemostasis tests routinely performed in hematology laboratories, often available 24/7, and potentially ordered urgently. These tests would comprise of the prothrombin time (PT), the PT converted to an international normalized ratio, the activated partial thromboplastin time (often called partial thromboplastin time in North American laboratories) and potentially the thrombin time, the D-dimer assay, and fibrinogen assays. Although other tests could feasibly be offered (testing feasible), there are good reasons for not including all of these other tests in all routine coagulation laboratories.

Abstract
Persistence of serum antiphospholipid antibodies (aPL) is associated with a high thrombotic risk, both arterial and venous, and with pregnancy complications. Due to the potential morbidity and mortality associated with the presence of aPL, identifying and recognizing risk factors for the development of aPL and thrombosis in aPL carriers may help to prevent and reduce the burden of disease. Multiple elements are involved in the pathomechanism of aPL development and aPL-related thrombosis such as genetics, malignancy, and infections. This review will address the role of both well-known risk factors and their evolution, and of emerging risk factors, including COVID-19, in the development of aPL and thrombosis in aPL carriers.

Abstract
Historically, neutrophils have been primarily regarded as short-lived immune cells that act as initial responders to antibacterial immunity by swiftly neutralizing pathogens and facilitating the activation of adaptive immunity. However, recent evidence indicates that their roles are considerably more complex than previously recognized. Neutrophils comprise distinct subpopulations and can interact with various immune cells, release granular proteins, and form neutrophil extracellular traps. These functions are increasingly recognized as contributing factors to tissue damage in autoimmune diseases. This review comprehensively examines the physiological functions and heterogeneity of neutrophils, their interactions with other immune cells, and their significance in autoimmune diseases, including systemic lupus erythematosus, rheumatoid arthritis, antiphospholipid syndrome, antineutrophil cytoplasmic antibody-associated vasculitis, multiple sclerosis, and others. This review aims to provide a deeper understanding of the function of neutrophils in the development and progression of autoimmune disorders.

Abstract
OBJECTIVE Substantial morbidity and mortality affect those with antiphospholipid antibodies (aPLs) and antiphospholipid syndrome (APS), yet patient experiences remain poorly understood. This research investigated patient experiences of aPL/APS diagnosis; effects on daily life; and healthcare and treatment. METHODS Patients aged ≥18 years with APS per the Revised Sapporo criteria or with ≥1 positive aPL on ≥2 occasions were recruited from a Canadian multidisciplinary APS clinic to participate in semi-structured in-depth interviews. Interviews were conducted virtually and transcribed verbatim for subsequent thematic analysis. RESULTS Twenty-one patients with aPLs/APS participated; 95.2% were female, mean (SD) age was 45.6 (15.0) years. Most (71.4%) had APS, and 71.4% had aPLs/APS with SLE. Results are presented around patient experiences of aPL/APS diagnosis, effects on daily life, and healthcare and treatment. Participants described medical complications/physical symptoms and the healthcare, lifestyle, and emotional impacts experienced around the time of aPLs/APS diagnosis. In addition to the physical and psychosocial impacts of living with aPLs/APS, patients reported modified leisure activities, altered employment trajectories, and positive and negative impacts on relationships. Impacts on family planning were also a critical component of the aPL/APS lived experience; participants shared experiences of miscarriage, other pregnancy complications, and medication-related challenges (e.g., with low-molecular-weight heparin injections). Challenging aspects of aPL/APS healthcare and treatment were also discussed, particularly related to the lifestyle, physical, and emotional burden of medication use. Although a lack of resources was described, participants expressed trust in healthcare providers when making management decisions or when seeking information. Suggestions for resources included the need for additional medication-related information, examples to help contextualize management behaviours, and additional information for those with aPLs/APS without SLE. CONCLUSION Patients highlighted how the diverse manifestations of aPLs/APS, accentuated by management-related challenges, impose considerable physical and psychosocial burdens. Results will inform the development of patient resources aligned with patient priorities.

Abstract
OBJECTIVE To assess the impact of concomitant systemic lupus erythematosus (SLE) on the clinicopathological manifestations of thrombotic antiphospholipid syndrome (APS). METHODS This single-centre, retrospective study compared clinical and antiphospholipid antibody (aPL) data from 118 patients, 58 with SLE-associated APS (SLE-APS), and 60 with primary APS. RESULTS Median follow-up was 13.9 (IQR 7.7-19.3) and 8.6 years (3.5-10.6) for the SLE-APS cohort and PAPS cohort, respectively. Age at diagnosis of APS was lower in the SLE-APS cohort (mean 35.9 vs PAPS: 46.7 years; p < 0.05). Distribution of aPL subtypes was similar across cohorts. 198 thrombotic events were identified overall (index plus recurrent), with venous thromboembolism (VTE) and arterial thrombosis each occurring in just over half of patients in both cohorts. Microvascular thrombosis (12.1% vs 0%), and a mixed (any combination of venous, arterial and microvascular) thrombotic phenotype (19.0% vs 6.7%, p = 0.05) were more prevalent in SLE-APS patients. Recurrent thrombosis incidence rates (∼0.5 events/10-patient years), and Kaplan-Meier recurrence-free survival after index thrombosis, were similar. In the PAPS cohort, only: (i) triple-aPL-positivity was associated with a significantly higher recurrent thrombosis event rate (incidence rate ratio 2.22, p = 0.03) and lower recurrence-free survival after first thrombosis (log-rank test p = 0.01); (ii) lupus anticoagulant (LA)-positivity was associated with higher prevalance of arterial thrombosis (RR 2.69, p = 0.01), and lower prevlance of VTE (RR 0.48, p < 0.001), versus LA-negativity. CONCLUSION Concomitant SLE does not appear to modify long-term recurrent thrombosis risk, or aPL phenotypes, in patients with APS. Triple-aPL-positivity and LA-positive status may have less influence on thrombotic outcomes in patients with SLE-APS compared to PAPS.

Abstract
STUDY QUESTION What are the outcomes of pregnancies exposed to hydroxychloroquine (HCQ) in women with a history of recurrent pregnancy loss (RPL), and what factors predict the course of these pregnancies beyond the first trimester? SUMMARY ANSWER In our cohort of pregnancies in women with a history of RPL exposed to HCQ early in pregnancy, we found that the only factor determining the success of these pregnancies was the number of previous miscarriages. WHAT IS KNOWN ALREADY Dysregulation of the maternal immune system plays a role in RPL. HCQ, with its dual immunomodulating and vascular protective effects, is a potential treatment for unexplained RPL. STUDY DESIGN, SIZE, DURATION The FALCO (Facteurs de récidive précoce des fausses couches) registry is an ongoing French multicenter infertility registry established in 2017 that includes women (aged from 18 to 49 years) with a history of spontaneous RPL (at least three early miscarriages (≤12 weeks of gestation (WG)) recruited from several university hospitals. PARTICIPANTS/MATERIALS, SETTING, METHODS Spontaneous pregnancies enrolled in the FALCO registry with an exposure to HCQ (before conception or at the start of pregnancy) were included. Pregnancies concomitantly exposed to tumor necrosis factor inhibitors, interleukin-1 and -2 inhibitors, intravenous immunoglobulin, and/or intravenous intralipid infusion, were excluded. Concomitant treatment with low-dose aspirin (LDA), low-molecular weight heparin (LMWH), progesterone, and/or prednisone was allowed. All patients underwent the recommended evaluations for investigating RPL. Those who became pregnant received obstetric care in accordance with French recommendations and were followed prospectively. The main endpoint was the occurrence of a pregnancy continuing beyond 12 WG, and the secondary endpoint was the occurrence of a live birth. MAIN RESULTS AND THE ROLE OF CHANCE One hundred pregnancies with HCQ exposure in 74 women were assessed. The mean age of the women was 34.2 years, and the median number of previous miscarriages was 5. Concomitant exposure was reported in 78 (78%) pregnancies for prednisone, 56 (56%) pregnancies for LDA, and 41 (41%) pregnancies for LMWH. Sixty-two (62%) pregnancies ended within 12 WG, the other 38 (38%) continuing beyond 12 WG. The risk of experiencing an additional early spontaneous miscarriage increased with the number of previous miscarriages, but not with age. The distributions of anomalies identified in RPL investigations and of exposure to other drugs were similar between pregnancies lasting ≤12 WG and those continuing beyond 12WG. The incidence of pregnancies progressing beyond 12 WG was not higher among pregnancies with at least one positive autoantibody (Ab) (i.e. antinuclear Ab titer ≥1:160, ≥1 positive conventional and/or non-conventional antiphospholipid Ab, and/or positive results for ≥1 antithyroid Ab) without diminished ovarian reserve (18/51, 35.3%) than among those without such autoantibody (18/45, 40.0%) (P = 0.63). Multivariate analysis showed that having ≤4 prior miscarriages was the only factor significantly predictive for achieving a pregnancy > 12 WG, after adjustment for age and duration of HCQ use prior to conception (adjusted odds ratio (OR) = 3.13 [1.31-7.83], P = 0.01). LIMITATIONS, REASONS FOR CAUTION Our study has limitations, including the absence of a control group, incomplete data for the diagnostic procedure for RPL in some patients, and the unavailability of results from endometrial biopsies, as well as information about paternal age and behavioral factors. Consequently, not all potential confounding factors could be considered. WIDER IMPLICATIONS OF THE FINDINGS Exposure to HCQ in early pregnancy for women with a history of RPL does not seem to prevent further miscarriages, suggesting limited impact on mechanisms related to the maternal immune system. STUDY FUNDING/COMPETING INTEREST(S) The research received no specific funding, and the authors declare no competing interests. TRIAL REGISTRATION NUMBER clinicaltrial.gov NCT05557201.

Abstract
BACKGROUND Activated partial thromboplastin time (APTT) is susceptible to reagent composition. This study aimed to investigate a large number of specimens and determine the cause of discrepancies. METHOD This study included 18,994 subjects who underwent coagulation tests at our hospital from May 2020 to December 2020. Measuring reagents included HemosIL SynthASil APTT (APTT-SS, Instrumentation Laboratory) and Coagpia APTT-N (APTT-N, Sekisui Medical). RESULTS A total of 451 patients demonstrated APTT-N of >39 seconds and an APTT-N/SS ratio of >1.3. A C-reactive protein (CRP) level of ≥1.4 mg/L demonstrated a significant positive correlation, with a higher APTT-N/SS indicating higher CRP levels. All 28 subjects receiving no anticoagulants and who had remaining specimens underwent a cross-mixing test (CMT). Of them, 17 were suspected for lupus anticoagulant (LA) by both the waveform shape and the index of circulating anticoagulant (ICA) value, 6 by the ICA value, and 5 were difficult to determine. CONCLUSION This study revealed that the APTT-N prolongation correlated with CRP degree and the transient involvement of LA in CMT results due to CRP. This study indicated various reactivities depending on the assay reagents used. Further testing is warranted if LA is suspected, considering the patient's background.

Abstract
OBJECTIVES Thrombosis in antiphospholipid syndrome (APS) involves in most cases the venous circulation. Why in some patients thrombotic APS affects the arterial circulation and in particular cerebral circulation is unknown. In previous studies, both patient characteristics and antiphospholipid antibody types and titers have been associated with arterial thrombosis. Aim of this study was to compare the clinical characteristics and laboratory findings of venous and arterial thrombotic APS from a large series of patients. METHODS Data were retrieved from the Start 2 antiphospholipid, a multicenter prospective register of long-term collected data from Thrombosis Centers in Italy. RESULTS Of 167 patients with thrombotic APS, 114 (68 %) had a venous and 53 (32 %) had an arterial event as first clinical manifestation. Several clinical characteristics and risk factors were different among groups in univariate analysis. Using logistic regression analysis, reduced creatinine clearance and hyperlipidemia were independent variable for the occurrence of arterial APS. Notably, no difference in antiphospholipid antibody profiles and aβ2-Glycoprotein I levels were found between groups. A higher adjusted global antiphospholipid syndrome score (aGAPSS) was found in arterial group indicating a possible high recurrence rate in arterial APS. CONCLUSIONS These data have pathophysiological and clinical implication since associated conditions might predispose patients to arterial rather than venous events and call to a close monitoring and treatment of arterial APS due to their increased tendency to recurrence.

Abstract
AIMS Echocardiographic assessment of cancer-associated non-bacterial thrombotic endocarditis (Ca-NBTE) is limited to case reports and small clinical series. The study aimed to identify heart valve abnormalities and its relation to embolic complications and cancer types. METHODS AND RESULTS Manual review of echocardiographic images and medical records of Mayo Clinic patients (31 March 2002-30 June 2022) was performed. Ca-NBTE in 111 patients (mean age 63.2 ± 9.7 years, 66.7% female) predominantly affected mitral valves (MV) (69), 56 aortic (AV), 8 tricuspid (TV), and rarely pulmonic (PV) (1). In 18 patients, 2 valves were involved, 3 and 4 valve involvement in only a single patient each. Embolic complications were prevalent (n = 102, 91.9%). Ca-NBTE affected MV more frequently on the upstream (atrial) (90% vs. 49.3%) and TV downstream (ventricular) side (75% vs. 37.5%). NBTE size (cm) varied significantly among valves, with TV hosting the largest masses (0.63-2.40 × 0.39-1.77), compared with MV [(0.11-1.81 × 0.11-1.62), (length P = 0.001; width P = 0.03)] and AV [(0.20-2.70 × 0.11-1.51), (length P = 0.001; width P = 0.056)]; MV masses were borderline longer in systemic compared with cerebral emboli (P = 0.057). Majority of MV (79.6%) and AV (69.6%) had thickened leaflets. NBTE lesions commonly affected closing margins (73.9% MV, 85.7% AV, and 62.5% of TV) but rarely commissures of MV (8.7%), yet fairly frequently of AV (41.1%). Five patients had severe regurgitation of MV and 5 AV. CONCLUSION Ca-NBTE manifests mainly as thrombotic mobile masses attached to thickened MV and AV, with distinct variations in size based on valve type. Embolic destination but not cancer type is associated with NBTE mass size and location.

Abstract
BACKGROUND Antiphospholipid syndrome (APS) is a chronic autoimmune disease characterized by venous or arterial thrombosis, pregnancy morbidity and a variety of other autoimmune and inflammatory complications. Here, we report a case of APS associated with multiple coronary thromboses.
CASE SUMMARY The patient, a 28-year-old male, suffered from recurrent coronary thromboses over a period of 31 months. Despite undergoing interventional coronary procedures, thrombolytic therapy, and anticoagulation treatment, the condition persisted intermittently. An extensive search for underlying thrombogenic factors revealed a diagnosis of APS. Accurate adjustment of the medication regimen led to the absence of further acute coronary syndrome (ACS) episodes during the subsequent 20-month follow-up. Although the patient occasionally experiences chest tightness, no further symptoms of distress have been reported.
CONCLUSION APS can manifest as ACS. Screening for rheumatologic and immunological conditions is essential when encountering patients with multiple coronary thromboses. Treatment strategy should include symptomatic relief and a targeted and aggressive approach to address the underlying pathophysiology.

Abstract
Autoimmune rheumatic diseases (ARDs) are a heterogeneous group of disorders characterized by an inappropriate immune reactivity against different body tissues. Patients affected by ARDs present increased cardiovascular morbidity and mortality, which significantly impacts long-term prognosis. Endothelial dysfunction, inflammation, oxidative stress, and autoimmunity are strictly involved in atherosclerosis progression and coronary microvascular dysfunction (CMD), both of which contribute to increased cardiovascular risk. CMD represents the inability of the coronary microvasculature to respond with vasodilation to increased cardiac metabolic demands and can be assessed by non-invasive and invasive imaging tests. Coronary flow velocity reserve assessed by echocardiography has been demonstrated to accurately identify ARDs patients with CMD. However, stress cardiac magnetic resonance (CMR) accurately assesses myocardial ischemia, perfusion, and viability in ARDs patients. The myocardial perfusion reserve index (MPRI) is a robust semiquantitative imaging marker that represents the vasodilatory capacity of the coronary microcirculation in response to a vasodilator stress. In the absence of significant coronary stenosis, ARDs patients revealed a reduced MPRI in comparison with the general population, regardless of the presence of myocardial fibrosis. Identification of CMD in asymptomatic patients could be crucial to precociously start targeted medical therapy, avoiding major adverse cardiac events in this clinical setting. This review aims to summarize the current evidence regarding CMD in ARDs patients, focusing on the role of stress CMR and the promising myocardial perfusion analysis.

Comparative assessment of the diagnostic performances of particle-based multianalyte technology and commercial ELISA for antiphospholipid autoantibody testing. Clin Chim Acta 2024; 562:119849. [PMID: 38977171 DOI: 10.1016/j.cca.2024.119849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2024] [Revised: 06/27/2024] [Accepted: 07/05/2024] [Indexed: 07/10/2024]
Abstract
BACKGROUND Diagnosing Antiphospholipid Syndrome (APS) relies heavily on laboratory findings, particularly the detection of specific antibodies like lupus anticoagulant (LA), IgG and/or IgM anti-cardiolipin (aCL), and IgG and/or IgM anti-β2 glycoprotein 1 (aB2GP1). Although ELISA is widely used in the US for this purpose, standardization between different assay methodologies remains challenging, leading to significant variability across laboratories. Particle-based multi-analyte technology (PMAT) offers a streamlined one-step detection for all six antiphospholipid (aPL) autoantibodies, covering aCL and aB2GP1 of IgA, IgG, and IgM isotypes. METHODS In this study involving 224 subjects, including 34 clinically diagnosed with APS, alongside 160 non-APS patients and 30 healthy donors, PMAT's performance was evaluated against commercial ELISA in detecting aPL antibodies. RESULTS At the manufacturer's suggested cutoff, PMAT exhibited sensitivity comparable to ELISA, albeit with a low to moderate decrease in specificity for certain antibodies. With anti-CL IgM alone, PMAT displayed a 17.7% decrease in sensitivity, accompanied by a corresponding 31.1% increase in specificity compared to ELISA. However, applying a stricter cutoff (88-90% specificity), IgA and IgM antibodies yielded 5.9-17.6% higher sensitivities with PMAT, and IgG antibodies displayed similar sensitivity. CONCLUSIONS In this study cohort, PMAT demonstrated higher or comparable sensitivity to that of commercial ELISA for all six aPL antibodies at a specificity cutoff near 90%. Notably, PMAT demonstrated superior sensitivity and specificity overall in detecting IgA aCL and aB2GP1 antibodies. This study highlights the potential of automated PMAT for detecting aPL antibodies in APS evaluation.

Abstract
Catastrophic Antiphospholipid Syndrome (CAPS) is a rare complication that can occur in patients with Antiphospholipid Syndrome (APS). CAPS occurs even more rarely during pregnancy/puerperium and pregnant patients, even less likely to show cardiac involvement without signs of damage on ultrasound and angiography with non-obstructive coronary arteries. We present a case of a 26-year-old breastfeeding woman, the youngest described with CAPS and acute myocardial infarction, whose diagnosis was made with cardiac magnetic resonance imaging (CMRI). A literature review of pregnant patients with similar problems was performed. There are diagnostic and therapeutic difficulties in treating these patients. CMRI demonstrated a transmural late enhancement area. A combination of therapies led to rapid clinical improvement. CMRI is an underused tool that reaffirms the pathophysiology of CAPS and leads clinicians to the possibility of a diffuse thrombotic process. CAPS involves more organs with high mortality rates. CMRI could be optimized in order to reach an early diagnosis and the most effective treatment. This study provides real-world evidence of the feasibility of MRI in a primary care setting during pregnancy/puerperium. Evidence from this study may influence future APS screening and inform policymakers regarding the use of leading MRI technology in the detection of the thrombotic process in a primary care setting.
