Antiphospholipid syndrome (APS) is an autoimmune disease characterized by antiphospholipid antibodies (aPL) associated with thrombosis and/or pregnancy morbidity. Most APS events are directly related to thrombotic events, which may affect small, medium or large vessels. Other clinical features like thrombocytopenia, nephropathy, cardiac valve disease, cognitive dysfunction and skin ulcers (called non-criteria manifestations) add significant morbidity to this syndrome and represent clinical situations that are challenging. APS was initially described in patients with systemic lupus erythematosus (SLE) but it can occur in patients without any other autoimmune disease. Despite the autoimmune nature of this syndrome, APS treatment is still based on anticoagulation and antiplatelet therapy.

Background: Accessory pathways (AP) are associated with an increased risk of atrioventricular reentry tachycardia (AVRT), presenting as a wide QRS tachycardia if the mechanism is antidromic. Rarely, AVRT may not respond to adenosine, suggesting a duodromic mechanism if the patient has multiple APs. Herein, we present a case of a male patient with multiple APs, wide QRS complex tachycardia, and resistance to adenosine.

Introduction: The area postrema, located on the floor of the fourth ventricle, regulates vomiting, fluid balance, osmoregulation, and immunomodulation. First documented in 1896, it has been a subject of scientific interest ever since. Area postrema syndrome (APS) is characterised by intractable nausea, vomiting, or hiccups, typically associated with neuromyelitis optica spectrum disorder (NMOSD).

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.

A 35-year-old woman with thyroid eye disease (TED) was found to have autoimmune polyglandular syndrome type II (APS-II) 1 year after developing symptoms of this rare syndrome, during which she underwent 8 emergency department visits before receiving a targeted endocrinology workup. Thyroid disease is the second most common autoimmune syndrome associated with APS-II after primary adrenal insufficiency. Identification of this syndrome is critical as it can be life-threatening if left untreated.

Machine learning and artificial intelligence tools were used to investigate the discriminatory potential of blood serum metabolites for thromboembolism and antiphospholipid syndrome (APS). H-NMR-based metabonomics data of the serum samples of patients with arterial or venous thromboembolism (VTE) without APS (n = 32), thrombotic primary APS patients (APS, n = 32), and healthy controls (HCs) (n = 32) were investigated. Unique metabolic profiles between VTE and HCs, APS and HCs, and between VTE and triple-positive APS groups were indicative of the significant alterations in the metabolic pathways of glycolysis, the TCA cycle, lipid metabolism, and branched-chain amino acid (BCAA) metabolism, and pointed to the complex pathogenesis mechanisms of APS and VTE.
