Experimental hyperammonemia in rats was accompanied by hemostatic disorders manifesting in coagulopathy (activation of the intrinsic pathway of blood coagulation) and suppression of platelet function. Ceruloplasmin in a total dose of 60 mg/kg effectively normalized coagulation hemostasis and functional activity of platelets by improving secretory processes in platelets and increasing aggregation rate.

Natural killer (NK) cells are a promising approach for cellular cancer immunotherapy and are being investigated to treat patients with multiple myeloma (MM). We found that MM patient blood NK cell frequencies were normal with increased activating receptors and cytotoxic granules, without evidence of functional exhaustion. Despite this activated state, MM target cells were resistant to conventional NK cells by unclear mechanisms.

Perioperative bleeding is and remains a major complication during and after surgical interventions, resulting in increased morbidity and mortality. The main causes of a non-primary vascular-related bleeding are congenital or multifactorial pre-existing hemostatic disorders that have not yet been diagnosed, the operating procedure itself and acquired hemostatic abnormalities as a secondary phenomenon, e.g.

Background: Multiple myeloma (MM) is more often characterized by clonal plasma cell proliferation restricted to the bone marrow. However, a small percentage of patients with MM develop extramedullary disease (EMD): this type of localization is found in 1.7%-4.

The 21st International Vasculitis Workshop, held in Barcelona, Spain, from April 7 to 10, 2024, highlighted advances in pediatric vasculitis, focusing on a holistic, multidisciplinary approach. Common childhood vasculitides, including IgA Vasculitis (IgAV) and Kawasaki Disease (KD), were discussed. The Ankara 2008 criteria for IgAV, endorsed by EULAR and PReS, were evaluated for their performance in adults, showing high sensitivity but necessitating further refinement for improved specificity.

Most factor VIII (FVIII) in circulation exists in a complex with von Willebrand factor (vWF). The interaction between FVIII and vWF is vital for normal hemostatic function, and disruptions in this interaction can lead to bleeding disorders such as von Willebrand disease or hemophilia. However, the impact of pathological mutations on the binding between FVIII and vWF remains largely uncharacterized.
