Polymorphisms in the IL-10 gene promoter could influence its expression and sepsis susceptibility. Results obtained by Dr Ling and colleagues demonstrated that the -1082A allele was significantly associated with lower lipopolysaccharide-induced IL-10 production in an allele-dose-dependent fashion. They also showed that this polymorphism was significantly associated with sepsis development after major trauma. These and other research data clearly demonstrated that the -1082 A G polymorphism in the IL-10 gene promoter has an important impact on susceptibility of sepsis and sepsis outcome. Dr Ling and colleagues performed a large prospective study including 308 patients with major trauma and determined that the genotype distribution of the IL-10 polymorphisms was associated with the sepsis morbidity rate and multiple organ dysfunction syndrome MODS scores 1 . The authors also investigated the association of polymorphisms with lipopolysaccharide-induced IL-10 production. Cytokine production varies between individuals due to genetic background and certain allelic variants of cytokine genes - in particular SNPs are associated with higher or lower cytokine production. The IL-10 5 -flanking region which controls transcription is polymorphic with two microsatellites and three SNPs -1082 -819 and -592 2 . Polymorphisms in the regulatory region of the IL-10 gene may influence its expression and hence could influence the susceptibility of sepsis 3 .
