Association of interleukin-(IL)10 haplotypes and serum IL-10 levels in the progression of childhood immune thrombocytopenic purpura.

Abstract

Derangement of genetic and immunological factors seems to have a pivotal role in the pathophysiology of immune thrombocytopenic purpura (ITP). We investigated interleukin(IL)-10 genetically determined expression in children with an acute progression of ITP (n=41) compared to young patients with chronic ITP (n=44) and healthy controls (n=60), and attempted to correlate IL-10 production with the course of the disease. We genotyped our study population for three single nucleotide polymorphisms at positions -1082 (A/G), -819 (C/T) and -592 (C/A) in the promoter region of the IL-10 gene. IL-10 levels were measured by enzyme-linked immunoassay. The IL-10 production in our study population was significantly higher in patients carrying the GCC haplotype than those bearing ACC and ATA haplotypes (6.9±1.5 vs 3.6±0.8 vs 3.3±0.3, p=0.03). The serum concentration of IL-10 was significantly higher in patients with an acute course of their disease, who mainly carried the GCC haplotype (92%), compared to chronic subjects, bearing the non-GCC haplotypes, and controls [17pg/mL (1.7-18) vs 3.5pg/mL (0.6-11) vs 3pg/mL (1-7), p<0.01)]. Our findings show that patients carrying the GCC-high producer IL-10 haplotype have an acute development of ITP and that IL-10 levels might represent a useful predictive biomarker of the disease course.
