Sažetak

Immunoglobulin A vasculitis (IgAV) or Henoch-Schönlein purpura is the most
prevalent systemic small vessel vasculitis in childhood. High mobility group box 1 protein (HMBG1)
is a pleiotropic cytokine that functions as a pro-inflammatory signal, important for the activation of
antigen-presenting cells and propagation of inflammation. HMGB1 is implicated in the pathophysiology
of a variety of inflammatory diseases. The aim of this study was to investigate the role of single
nucleotide polymorphism rs41369348 for HMGB1 gene in the susceptibility and clinical features
of patients meeting the classification criteria for IgAV. DNA was extracted from blood cells of 76
children with IgAV and 150 age-matched healthy controls. Clinical data and laboratory parameters
were collected for all IgAV patients. Although there was a higher frequency of heterozygous A/delA
genotype of this gene polymorphism in IgAV group as compared with control group, no genotype
difference was observed between these two groups. No statistically significant genotype differences
were disclosed when patients with different IgAV clinical features were compared. In conclusion, in
this study, polymorphism rs41369348 for HMGB1 was not associated with increased susceptibility to
childhood IgAV, its severity or different clinical manifestations.
