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 (Online ahead of print). doi: 10.1111/bjh.18732.
