Antiphospholipid antibodies may interfere with the PC pathway, displaying a resistance to the activated PC (resistant phenotype). This effect was evaluated by the APCR and the ProCG systems in 36 lupus anticoagulant samples, yielding abnormal results in 47% of APCR(original), 17% of APCR(modified), and 22% of ProCG test. ProCG values correlated with APCR(original) but not with APCR(modified). Most of lupus anticoagulants affecting the PC pathway showed abnormal APCR(original) results but not abnormal ProCG values. The different behavior between both systems may be due to the heterogeneity of the antibodies or could be attributed to the fact that, in the ProCG, a PC activator is added, while the APCR employs already activated exogenous PC.

Little is known about how patients with antiphospholipid syndrome (APS) or antiphospholipid antibodies (aPL) access and trust health information. This research aimed to: describe the sources of information most frequently accessed/trusted by patients with APS/aPL; identify if individuals with APS/aPL perceived their health had been negatively impacted by various sources and document obstacles to accessing health information. Patients meeting Revised Sapporo Criteria for APS or with ≥1 positive aPL on ≥2 occasions were recruited to an online survey regarding their health information use at diagnosis and within 6 months preceding survey completion.

Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease with an important course due to systemic compromise. SLE is frequently associated with antiphospholipid syndrome, and pulmonary thromboembolism (PE) is particularly common. It is extremely rare for PE to be the initial clinical presentation and even more uncommon for it to coincide with cardiac tamponade, representing a challenge in diagnosis and management.

Coagulation factors are intrinsically expressed in various brain cells, including astrocytes and microglia. Their interaction with the inflammatory system is important for the well-being of the brain, but they are also crucial in the development of many diseases in the brain such as stroke and traumatic brain injury. The cellular effects of coagulation are mediated mainly by protease-activated receptors.

Anti-phosphatidylserine/prothrombin antibodies (aPS/PT) are classified as non-criteria antiphospholipid antibodies (aPL), and are strongly associated with thrombosis and pregnancy complications linked to antiphospholipid syndrome (APS). This study aimed to investigate whether aPS/PT positivity is associated with adverse outcomes in vitro fertilization (IVF). The study included infertile women who tested positive aPS/PT and underwent IVF cycles, as well as infertile controls with pure tubal etiology.

APS is an autoimmune disorder characterized by thrombosis and pregnancy complications, primarily driven by aPLs such as LA, aCL and anti-β2 glycoprotein I (a-β2GPI). Despite advances in anticoagulation therapies, managing refractory APS cases remains challenging. Emerging therapies, including rituximab, eculizumab and HCQ, show potential in addressing the underlying mechanisms of APS.
