    Factors associated with first thrombosis in patients presenting with obstetric antiphospholipid syndrome (APS) in the APS Alliance for Clinical Trials and International Networking Clinical Database and Repository: a retrospective study
    (2019) JESUS, G. R. de; SCIASCIA, S.; ANDRADE, D.; BARBHAIYA, M.; TEKTONIDOU, M.; BANZATO, A.; PENGO, V.; JI, L.; MERONI, P. L.; UGARTE, A.; COHEN, H.; BRANCH, D. W.; ANDREOLI, L.; BELMONT, H. M.; FORTIN, P. R.; PETRI, M.; RODRIGUEZ, E.; CERVERA, R.; KNIGHT, J. S.; ATSUMI, T.; WILLIS, R.; NASCIMENTO, I. S.; ROSA, R.; ERKAN, D.; LEVY, R. A.
    Objective To evaluate the subsequent rate of thrombosis among women with obstetric antiphospholipid syndrome (Ob-APS) in a multicentre database of antiphospholipid antibody (aPL)-positive patients, and the clinical utility of the adjusted Global Antiphospholipid Syndrome Score (aGAPSS), a validated tool to assess the likelihood of developing new thrombosis, in this group of patients. Design Retrospective study. Setting The Antiphospholipid Syndrome Alliance for Clinical Trials and International Networking Clinical Database and Repository. Population Women with Ob-APS. Methods Comparison of clinical and laboratory characteristics and measurement of aGAPSS in women with Ob-APS, with or without thrombosis, after initial pregnancy morbidity (PM). Main outcome measures Risk factors for thrombosis and aGAPSS. Results Of 550 patients, 126 had Ob-APS; 74/126 (59%) presented with thrombosis, and 47 (63%) of these women developed thrombosis after initial PM, in a mean time of 7.6 +/- 8.2 years (4.9/100 patient years). Younger age at diagnosis of Ob-APS, additional cardiovascular risk factors, superficial vein thrombosis, heart valve disease, and multiple aPL positivity increased the risk of first thrombosis after PM. Women with thrombosis after PM had a higher aGAPSS compared with women with Ob-APS alone [median 11.5 (4-16) versus 9 (4-13); P = 0.0089]. Conclusion Based on a retrospective analysis of our multicentre aPL database, 63% of women with Ob-APS developed thrombosis after initial obstetric morbidity; additional thrombosis risk factors, selected clinical manifestations, and high-risk aPL profile increased the risk. Women with subsequent thrombosis after Ob-APS had a higher aGAPSS at entry to the registry. We believe that aGAPSS is a valid tool to improve risk stratification in aPL-positive women.

    Damage measured by Damage Index for Antiphospholipid Syndrome (DIAPS) in antiphospholipid antibody-positive patients included in the APS ACTION registry
    (2024) BALBI, Gustavo G. M.; AHMADZADEH, Yasaman; TEKTONIDOU, Maria G.; PENGO, Vittorio; SCIASCIA, Savino; UGARTE, Amaia; BELMONT, H. Michael; LOPEZ-PEDRERA, Chary; FORTIN, Paul R.; WAHL, Denis; GEROSA, Maria; JESUS, Guilherme R. de; JI, Lanlan; ATSUMI, Tatsuya; EFTHYMIOU, Maria; BRANCH, D.

    Objectives Our primary objective was to quantify damage burden measured by Damage Index for Antiphospholipid Syndrome (DIAPS) in aPL-positive patients with or without a history of thrombosis in an international cohort (the APS ACTION cohort). Secondly, we aimed to identify clinical and laboratory characteristics associated with damage in aPL-positive patients. Methods In this cross-sectional study, we analysed the baseline damage in aPL-positive patients with or without APS classification. We excluded patients with other autoimmune diseases. We analysed the demographic, clinical and laboratory characteristics based on two subgroups: (i) thrombotic APS patients with high vs low damage; and (ii) non-thrombotic aPL-positive patients with vs without damage. Results Of the 826 aPL-positive patients included in the registry as of April 2020, 586 with no other systemic autoimmune diseases were included in the analysis (412 thrombotic and 174 non-thrombotic). In the thrombotic group, hyperlipidaemia (odds ratio [OR] 1.82; 95% CI 1.05, 3.15; adjusted P = 0.032), obesity (OR 2.14; 95% CI 1.23, 3.71; adjusted P = 0.007), a & beta;(2)GPI high titres (OR 2.33; 95% CI 1.36, 4.02; adjusted P = 0.002) and corticosteroid use (ever) (OR 3.73; 95% CI 1.80, 7.75; adjusted P < 0.001) were independently associated with high damage at baseline. In the non-thrombotic group, hypertension (OR 4.55; 95% CI 1.82, 11.35; adjusted P = 0.001) and hyperlipidaemia (OR 4.32; 95% CI 1.37, 13.65; adjusted P = 0.013) were independent predictors of damage at baseline; conversely, single aPL positivity was inversely correlated with damage (OR 0.24; 95% CI 0.075, 0.77; adjusted P = 0.016). Conclusions DIAPS indicates substantial damage in aPL-positive patients in the APS ACTION cohort. Selected traditional cardiovascular risk factors, steroids use and specific aPL profiles may help to identify patients more prone to present with a higher damage burden.

    Controversies in the Management of Antiphospholipid Syndrome
    (2023) PORTA, Sabrina V.; ANDRADE, Danieli Castro Oliveira de; ERKAN, Doruk; GOMEZ-PUERTA, Jose A.; JARA, Luis J.; MOREYRA, Paula Alba; PONS-ESTEL, Guillermo J.
    Strategies to prevent thrombosis in antiphospholipid antibody (aPL)-positive patients are of the utmost importance. The risk of thrombosis in patients with aPLs varies, depending on additional venous thrombosis and cardiovascular risk factors, as well as associated comorbidities. Recurrent thrombosis despite treatment with vitamin K antagonists is relatively common in daily practice. In this context, the effectiveness of the new direct oral anticoagulants in antiphospholipid syndrome is debated, as well as that of low-dose aspirin for primary thromboprophylaxis. There is an urgent unmet need to recognize the subgroup of patients that may benefit from low-dose aspirin use. Here we also discuss different points of view on primary and secondary thrombosis preventions in aPL-positive patients, which were presented as a debate during the 2021 PANLAR Congress (Pan-American League of the Association of Rheumatology) and that was organized by GESAF (Argentine Society of Rheumatology APS Study Group). It is the intention of this article to provide a useful discussion to aid treatment decision-making in daily clinical practice.

    Antiphospholipid syndrome damage index (DIAPS): distinct long-term kinetic in primary antiphospholipid syndrome and antiphospholipid syndrome related to systemic lupus erythematosus
    (2020) TORRICELLI, A. Kuhl; UGOLINI-LOPES, M. Remiao; BONFA, E.; ANDRADE, D.
    Background Antiphospholipid syndrome (APS) is an acquired thrombophilia that affects young productive individuals, with permanent damage and negative impact on quality of life. Recently, a damage index specific for APS (DIAPS) was developed. There are, however, no data regarding the comparison of its performance and long-term damage in primary antiphospholipid syndrome (PAPS) and APS related to systemic lupus erythematosus (SLE; APS + SLE). The primary purpose of this study was therefore to compare the long-term damage in patients with these conditions. Methods This is a retrospective analysis of a single tertiary center cohort followed for approximately 10 years using a standardized prospective electronic chart database. Fifty consecutive PAPS patients age matched with 50 APS+SLE patients were consecutively selected for the study, and DIAPS was calculated once a year during follow-up. Long-term damage and damage kinetics in both groups were compared. Results PAPS and APS + SLE had comparable age (47.10 +/- 12.4 vs. 44.04 +/- 10.80 years; p = 0.19) and time of follow-up (9.40 +/- 3.60 vs. 10.94 +/- 4.50 years; p = 0.06). At diagnosis, PAPS had higher DIAPS than APS + SLE (1.72 +/- 1.17 vs. 0.82 +/- 0.96; p < 0.001). At the end of the 10-year follow-up, both groups presented comparable mean damage scores (2.04 +/- 1.50 vs. 2.24 +/- 1.61; p = 0.52). The damage increment throughout the observation period for PAPS was solely 35%, whereas for APS + SLE it was gradual, persistent and reached 139% at the end of follow-up, with a total damage increment for PAPS lower than APS + SLE (0.43 +/- 0.30 vs. 1.22 +/- 1.24; p < 0.001). Of note, the frequency of individuals who acquired damage was lower in PAPS than in APS + SLE (32% vs. 71%; p < 0.001). PAPS also had a longer delay in diagnosis than APS + SLE (4.00 +/- 4.20 vs. 2.54 +/- 3.05 years; p = 0.04). This delay was positively correlated with a higher damage score at diagnosis (r = 0.36, p < 0.001) in all groups. Conclusion We identified a distinct pattern of damage in PAPS and APS related to SLE. Damage in PAPS is an early event, while APS+SLE is associated with higher long-term damage, with a striking increment of damage along the follow-up. A diagnosis delay is correlated with higher damage scores. Damage surveillance therefore requires different approaches for these two conditions.

    (2021) GKROUZMAN, Elena; SEVIM, Ecem; FINIK, Jackie; ANDRADE, Danieli; PENGO, Vittorio; SCIASCIA, Savino; TEKTONIDOU, Maria G.; UGARTE, Amaia; CHIGHIZOLA, Cecilia B.; BELMONT, H. Michael; LOPEZ-PEDRERA, Chary; JI, Lanlan; FORTIN, Paul; EFTHYMIOU, Maria; JESUS, Guilherme Ramires de; BRANCH, D. Ware; NALLI, Cecilia; PETRI, Michelle; RODRIGUEZ, Esther; CERVERA, Ricard; KNIGHT, Jason S.; ATSUMI, Tatsuya; WILLIS, Rohan; BERTOLACCINI, Maria Laura; COHEN, Hannah; RAND, Jacob; ERKAN, Doruk
    Objective. The APS ACTION Registry studies long-term outcomes in persistently antiphospholipid anti-body (aPL)-positive patients. Our primary objective was to determine whether clinically meaningful aPL profiles at baseline remain stable over time. Our secondary objectives were to determine (1) whether baseline characteristics differ between patients with stable and unstable aPL profiles, and (2) predictors of unstable aPL profiles over time. Methods. A clinically meaningful aPL profile was defined as positive lupus anticoagulant (LAC) test and/or anticardiolipin (aCL)/anti-beta(2) glycoprotein-I (anti-(beta(2)-GPI) IgG/M >= 40 U. Stable aPL profile was defined as a clinically meaningful aPL profile in at least two-thirds of follow-up measurements. Generalized linear mixed models with logit link were used for primary objective analysis. Results. Of 472 patients with clinically meaningful aPL profile at baseline (median follow-up 5.1 yrs ), 366/472 (78%) patients had stable aPL profiles over time, 54 (11%) unstable, and 52 (11%) inconclusive. Time did not significantly affect odds of maintaining a clinically meaningful aPL profile at follow-up in univariate (P= 0.906) and multivariable analysis (P= 0.790). Baseline triple aPL positivity decreased (OR 0.25, 95% CI 0.10-0.64, P = 0.004) and isolated LAC test positivity increased (OR 3.3, 95% CI 1.53-7.13, P = 0.002) the odds of an unstable aPL profile over time. Conclusion. Approximately 80% of our international cohort patients with clinically meaningful aPL profiles at baseline remain stable at a median follow-up of 5 years; triple aPL-positivity increase the odds of a stable aPL profile. These results will guide future validation studies of stored blood samples through APS ACTION Core Laboratories.

    Background Variability remains a challenge in lupus anticoagulant (LA) testing. Objective To validate LA test performance between Antiphospholipid Syndrome Alliance for Clinical Trials and International Networking (APS ACTION) Core laboratories and examine agreement in LA status between Core and local/hospital laboratories contributing patients to this prospective registry. Methods Five Core laboratories used the same reagents, analyzer type, protocols, and characterized samples for LA validation. Non-anticoagulated registry samples were retested at the corresponding regional Core laboratories and anticoagulated samples at a single Core laboratory. Categorical agreement and discrepancies in LA status between Core and local/hospital laboratories were analyzed. Results Clotting times for the reference/characterized plasmas used for normalized ratios were similar between Core laboratories (CV <4%); precision and agreement for LA positive/negative plasma were similar (all CV <= 5%) in the four laboratories that completed both parts of the validation exercise; 418 registry samples underwent LA testing. Agreement for LA positive/negative status between Core and local/hospital laboratories was observed in 87% (115/132) non-anticoagulated and 77% (183/237) anticoagulated samples. However, 28.7% (120/418) of samples showed discordance between the Core and local/hospital laboratories or equivocal LA results. Some of the results of the local/hospital laboratories might have been unreliable in 24.7% (41/166) and 23% (58/252) of the total non-anticoagulated and anticoagulated samples, respectively. Equivocal results by the Core laboratory might have also contributed to discordance. Conclusions Laboratories can achieve good agreement in LA performance by use of the same reagents, analyzer type, and protocols. The standardized Core laboratory results underpin accurate interpretation of APS ACTION clinical data.

    Distinct features of youth-onset primary antiphospholipid syndrome
    (2021) SILVA, Carla Baleeiro; DURAN, Camila S. C.; SIGNORELLI, Flavio; BALBI, Gustavo G. M.; BONFA, Eloisa; ANDRADE, Danieli C. O.
    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). Methods This was a cross-sectional study derived from two rheumatology outpatient clinics. Patients who fulfilled Sidney criteria and who were 15 years of age or older at disease onset were included. Secondary APS patients were excluded. We subdivided patients into two groups: youth- (15-24 years) and adult-onset (over 24 years) and compared them regarding demographic characteristics, criteria and non-criteria manifestations, cardiovascular risk factors, and aPL status. For the pregnancy outcomes analysis, ever-pregnant patients were divided in three groups: youth-onset, early adult-onset (25-34 years), and late adult-onset (35-49 years). Results A total of 250 consecutive PAPS patients were included. Groups had a comparable female and Caucasian distribution. We found a similar disease duration (14.0 +/- 7.9 vs 17.0 +/- 10.1 years, p = 0.079) and similar rates of thrombotic arterial (34.2% vs. 42.0%, p = 0.250) and venous events (69.7% vs. 69.5%, p = 0.975) between them. Skin ulcers were more frequent in the youth-onset group (17.1% vs. 4.0%, p = 0.001), whereas nephropathy was less common (1.3% vs. 8.0%, p = 0.039). No differences were observed for the other criteria and non-criteria manifestations. The adult-onset group presented more frequently with hypertension (p = 0.002), hyperlipidemia (p = 0.008), and smoking (p = 0.003). The youth-onset group presented a higher frequency of obstetric events as the first manifestation of PAPS (30.3% vs. 21.7%, p = 0.005), with worse pregnancy outcomes, namely, fetal death (58.5% vs. 46.4% vs. 24.1%, p = 0.012) and premature delivery (35.8% vs. 19.0% vs. 10.3%, p = 0.016). Of note, all groups had a comparable number of pregnancies (2.81 +/- 2.52 vs 2.74 +/- 2.07, p = 0.899). Conclusion This study provides novel evidence that youth-onset PAPS presents a higher frequency of obstetric complications as its first manifestation, with an increased risk of fetal death and preterm delivery. Early recognition of this condition by obstetricians is essential to improve prognosis.

    Immunogenicity, safety, and antiphospholipid antibodies after SARS-CoV-2 vaccine in patients with primary antiphospholipid syndrome
    (2022) SIGNORELLI, Flavio; BALBI, Gustavo Guimaraes Moreira; AIKAWA, Nadia E.; SILVA, Clovis A.; KUPA, Leonard de Vinci Kanda; MEDEIROS-RIBEIRO, Ana C.; YUKI, Emily F. N.; PASOTO, Sandra G.; SAAD, Carla G.

    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. Methods This prospective controlled phase-4 study of PAPS patients and a control group (CG) consisted of a two-dose Sinovac-CoronaVac (D0/D28) and blood collection before vaccination (D0), at D28 and 6 weeks after second dose (D69) for immunogenicity/aPL levels. Outcomes were seroconversion (SC) rates of anti-SARS-CoV-2 S1/S2 IgG and/or neutralizing antibodies (NAb) at D28/D69 in naive participants. Safety and aPL production were also assessed. Results We included 44 PAPS patients (31 naive) and 132 CG (108 naive) with comparable age (p=0.982) and sex (p>0.999). At D69, both groups had high and comparable SC (83.9% vs. 93.5%, p=0.092), as well as NAb positivity (77.4% vs. 78.7%, p=0.440), and NAb-activity (64.3% vs. 60.9%, p=0.689). Thrombotic events up to 6 months or other moderate/severe side effects were not observed. PAPS patients remained with stable aPL levels throughout the study at D0 vs. D28 vs. D69: anticardiolipin (aCL) IgG (p=0.058) and IgM (p=0.091); anti-beta-2 glycoprotein I (a beta 2GPI) IgG (p=0.513) and IgM (p=0.468). Conclusion We provided novel evidence that Sinovac-CoronaVac has high immunogenicity and safety profile in PAPS. Furthermore, Sinovac-CoronaVac did not trigger thrombosis nor induced changes in aPL production.

    Ocular findings in asymptomatic patients with primary antiphospholipid syndrome
    (2022) NETO, Taurino S. R.; NETO, Epitacio D. S.; BALBI, Gustavo G. M.; SIGNORELLI, Flavio; HIGASHI, Alex H.; MONTEIRO, Mario Luiz R.; BONFA, Eloisa; ZACHARIAS, Leandro C.; ANDRADE, Danieli C. O.
    BackgroundPrimary 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.PurposeTo perform a multimodal evaluation, including the use of Optical Coherence Angiotomography (OCTA), in patients with PAPS without ocular complaints and compare with healthy individuals.MethodsWe performed a complete structural and functional ophthalmological evaluation using OCTA and microperimetry exam in patients with PAPS, followed at a tertiary Rheumatology outpatient clinic.ResultsWe included 104 eyes of 52 subjects [PAPS without ocular complaints (N = 26) and healthy individuals (N = 26)]. Among PAPS patients, 21 were female (80.8%) and 21 (80.8%) were Caucasians. PAPS manifestations were venous (65.4%), arterial thrombosis (34.6%), and obstetrical (34.6%) and all of them had lupus anticoagulant. Ophthalmologic findings were more frequent in PAPS compared to healthy individuals (19.2% vs. 0%, p = 0.05). The most common retinal change was paracentral acute middle maculopathy (PAMM) (3 patients, 5 eyes), followed by drusen (1 patient, 2 eyes) and pachychoroid pigment epitheliopathy (PPE) (1 patient, 1 eye). Hypertension and hyperlipidemia were present in 100% of the PAPS patients with PAMM, while only six patients (26.1%) with PAPS without PAMM presented these two risk factors together (p = 0.03).ConclusionsWe provide novel evidence that approximately 20% of our asymptomatic PAPS patients without ocular symptoms have ophthalmologic findings that require early identification and careful surveillance focusing on minimizing systemic and vascular risk factors.

    COVID-19 and antiphospholipid antibodies: A position statement and management guidance from AntiPhospholipid Syndrome Alliance for Clinical Trials and InternatiOnal Networking (APS ACTION)
    (2021) WANG, Xin; GKROUZMAN, Elena; ANDRADE, Danieli Castro Oliveira; ANDREOLI, Laura; BARBHAIYA, Medha; BELMONT, H. Michael; BRANCH, David Ware; JESUS, Guilherme R. de; EFTHYMIOU, Maria; RIOS-GARCES, Roberto; GEROSA, Maria; HASBANI, Georges El; KNIGHT, Jason; MERONI, Pier Luigi; PAZZOLA, Giulia; PETRI, Michelle; RAND, Jacob; SALMON, Jane; TEKTONIDOU, Maria; TINCANI, Angela; UTHMAN, Imad W.; ZUILY, Stephane; ZUO, Yu; LOCKSHIN, Michael; COHEN, Hannah; ERKAN, Doruk
    Coronavirus disease 2019 (COVID-19) is associated with a high rate of thrombosis. Prolonged activated partial thromboplastin times (aPTT) and antiphospholipid antibodies (aPL) are reported in COVID-19 patients. The majority of publications have not reported whether patients develop clinically relevant persistent aPL, and the clinical significance of new aPL-positivity in COVID-19 is currently unknown. However, the reports of aPL-positivity in COVID-19 raised the question whether common mechanisms exist in the pathogenesis of COVID-19 and antiphospholipid syndrome (APS). In both conditions, thrombotic microangiopathy resulting in microvascular injury and thrombosis is hypothesized to occur through multiple pathways, including endothelial damage, complement activation, and release of neutrophil extracellular traps (NETosis). APS-ACTION, an international APS research network, created a COVID-19 working group that reviewed common mechanisms, positive aPL tests in COVID-19 patients, and implications of COVID-19 infection for patients with known aPL positivity or APS, with the goals of proposing guidance for clinical management and monitoring of aPL-positive COVID-19 patients. This guidance also serves as a call and focus for clinical and basic scientific research.
