    Abstract Antinuclear antibodies (ANA) have been detected in children with primary immune thrombocytopaenia (ITP), but the effect of ANA titres on clinical outcomes is unclear. Liu et al. retrospectively analysed a cohort of 324 children with primary ITP with a median follow-up time of 25 months and found that patients with high-ANA titres (≥1:160) had lower platelet counts at the onset with a higher subsequent platelet count recovery rate, and additionally were at an increased risk to develop autoimmune disease. These data highlight the possible predictive potential of ANA titres with respect to platelet counts and the development of autoimmunity in children with primary ITP. Commentary on: Liu, et al. The effect of antinuclear antibody titre and its variation on outcomes in children with primary immune thrombocytopaenia. Br J Haematol 2023;202:412-421.

    Abstract Autoimmune-responses leading to increased destruction of red blood cells occur in autoimmune haemolytic anaemia (AIHA). The pathophysiology of AIHA is multifactorial and not fully understood, and clinically it remains challenging to manage relapsed and treatment-refractory cases. Rabelo and colleagues conduct metabolomic profiling in plasma of 26 patients with primary warm AIHA, with consideration of haemolytic activity and relapse occurrence. They identify distinct metabolites to be increased in primary warm AIHA patients, thereby providing an encouraging basis for further validation and exploration of metabolomic profiling as a predictive tool for the management of AIHA. Commentary on: Rabelo et al. Metabolomic profile in patients with primary warm autoimmune haemolytic anaemia. Br J Haematol 2023;200:140-149.

    Abstract Childhood immune thrombocytopenia (ITP) is an acquired haematological disorder characterized by low platelet counts, with a disease course which is usually benign and self-limiting within 3-12 months. An estimated 28%, however, continue to develop chronic ITP and may experience bleeding symptoms and an impaired quality of life. Treatment options in case of severe bleedings include corticosteroids, anti-D or intravenous immunoglobulins (IVIg). The general working mechanism of IVIg remains unresolved and a matter of debate. Schmugge et al now identify that IVIg may have the ability to improve thrombin-induced platelet activation and enhance thrombin generation in a prospective study of 23 children with primary ITP, demonstrating that besides increasing platelet counts IVIg can be efficacious on the level of thrombin-induced platelet activation and coagulation support. Commentary on: Schmugge et al. IVIg treatment increases thrombin activation of platelets and thrombin generation in paediatric patients with immune thrombocytopenia. Br J Haematol 2023;201:1209-1219.

    Abstract Kawasaki disease (KD) is an acute vasculitis of early childhood with unknown cause, which can be complicated by coronary artery lesions resulting in thrombosis. Fu and coworkers identify thymic stromal lymphopoietin (TSLP) to be increased in KD patients with thrombosis. They demonstrate that TSLP can activate platelets, induce mitophagy and trigger thrombus formation in vitro, suggesting that TSLP may have potential as a therapeutic target against KD-associated thrombosis. Commentary on: Fu L, et al. TSLP induces platelet mitophagy and promotes thrombosis in Kawasaki disease. Br J Haematol. 2023; 200:776-791.

    Abstract Therapeutic management of patients with immune thrombocytopenia (ITP) remains challenging; however, thrombopoietin receptor agonists (TPO-RAs) have revolutionised the treatment landscape of ITP. It is increasingly hypothesised that TPO-RAs may have an immune modulatory role and Pizzi and colleagues provide evidence in support of this by demonstrating that TPO-RA treatment restores the decreased regulatory T cell (Treg) numbers in the splenic microenvironment of patients with ITP. Commentary on: Pizzi M, Vianello F, Binotto G, Vianelli N, Carli G, Auteri G, et al. Thrombopoietin receptor agonists increase splenic regulatory T-cell numbers in Immune Thrombocytopenia.
