Impact of Lupus Anticoagulant on INR Using Recombinant Prothrombin Time Reagent.
Am J Case Rep
January 2025
Department of Clinical Diagnostic Laboratories, Hospital Al-Sultan Abdullah, Puncak Alam, Selangor, Malaysia.
BACKGROUND Lupus anticoagulants (LA) can interfere with routine coagulation tests such as the activated partial thromboplastin time (aPTT) and prothrombin time (PT). The international normalized ratio (INR) is derived from PT and is used to monitor warfarin therapy. A positive LA result is one of the laboratory criteria of the 2023 ACR/EULAR antiphospholipid syndrome (APS) classification criteria.

The coronavirus disease 2019 (COVID-19) pandemic had significant global health impact. Like systemic autoimmune diseases, COVID-19 may manifest with systemic and heterogenous clinical presentations. This study aimed to evaluate the prevalence of autoimmune rheumatic manifestations among a cohort of Egyptian patients with COVID-19 infection.

Institute of Clinical Chemistry and Laboratory Medicine, University Medical Center Mainz, Mainz, Germany.
Background: Thrombocytopenia is one of the most common manifestations of the antiphospholipid syndrome (APS). However, its causes are still poorly defined. We have shown recently that antiphospholipid antibodies (aPL) directed against β2-glycoprotein I (β2GPI) of the IgG isotype induced platelet activation and aggregation while aPL directed against cardiolipin and anti-β2GPI IgM had no effect.

Background: Patients with systemic lupus erythematosus (SLE) suffered from an increasing risk of cardiovascular diseases. In this multi-center prospective study, we aimed to determine the association between antiphospholipid antibodies (aPLs) and future atherosclerotic cardiovascular disease (ASCVD) in SLE.
Methods: In total, 1573 SLE patients were recruited based on the Chinese SLE Treatment and Research group (CSTAR) registry.
Is the 99th Percentile Cutoff Still Relevant? A Single-Center Assessment of Different Thresholds for Diagnosing Antiphospholipid Syndrome.
J Appl Lab Med
December 2024
ARUP Institute for Clinical and Experimental Pathology, Salt Lake City, UT, United States.
Background: The 2023 American College of Rheumatology and modified Sapporo criteria for antiphospholipid syndrome (APS) recommend ELISA to detect anticardiolipin (aCL) and anti-β2-glycoprotein I (aβ2GP1) IgG/IgM antibodies, focusing on moderate to high levels or exceeding the 99th percentile. This study aims to establish the 99th percentile threshold for anti-phospholipid (aPL) antibodies and compare the diagnostic accuracies of these thresholds with manufacturer cutoffs using 2 methodologies.
Methods: The 99th percentile cutoffs for aPL antibodies from 305 healthy donors were established using Aptiva, Particle-Based Multi-Analyte Technology (PMAT), and QUANTA Lite (QL) ELISA, following nonparametric reference interval estimation.
