COVID-19 and antiphospholipid antibodies: A position statement and management guidance from AntiPhospholipid Syndrome Alliance for Clinical Trials and InternatiOnal Networking (APS ACTION).

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.

Pregnancy and Rheumatic Disease: Experience at a Single Center in New York City During the COVID-19 Pandemic.

OBJECTIVE: The present study was undertaken to evaluate the pregnancy experiences of women receiving care in the division of rheumatology at a major academic center in New York City during the COVID-19 pandemic. METHODS: A web-based COVID-19 survey was emailed to 26,045 patients who were followed in the division of rheumatology at a single center in New York City. Women ages 18-50 years were asked about their pregnancy. We compared the COVID-19 experience between pregnant and nonpregnant women and also explored the impact of the pandemic on prenatal care and perinatal outcomes. RESULTS: Among 7,094 of the 26,045 respondents, 1,547 were women ages 18-50 years, with 61 (4%) reporting being pregnant during the pandemic. The prevalence of self-reported COVID-19 was similar in pregnant and nonpregnant women (8% versus 9%, respectively; P = 0.76). Among women with COVID-19, pregnant women had a shorter duration of symptoms (P < 0.01) and were more likely to experience loss of smell or taste (P = 0.02) than nonpregnant women. Approximately three-fourths of women had a systemic rheumatic disease, with no differences when stratified by pregnancy or COVID-19 status. In all, 67% of pregnant women noted changes to prenatal care during the pandemic, and 23% of postpartum women stated that the pandemic affected delivery. CONCLUSION: Among women followed in the division of rheumatology at a major center in New York City, pregnancy was not associated with increased self-reported COVID-19. Pregnancy was associated with a shorter duration of COVID-19 symptoms and a higher prevalence of loss of smell or taste. The COVID-19 pandemic impacted prenatal care for the majority of pregnant patients.
