Background: IL-10 is an important pleiotropic, immunoregulatory and anti-inflammatory cytokine which plays a significant role in the pathogenesis of psoriasis.

Objective: The aim of the present study was to determine whether the three polymorphic sites of the IL-10 gene, haplotype and serum level confer susceptibility to psoriasis.

Method: 200 psoriatic patients and 200 controls were genotyped for three IL-10 polymorphic sites by ARMS polymerase chain reaction. Serum levels of IL -10 were measured by ELISA.

Results: Our results demonstrated that polymorphism of IL-10 -592 C/A (adjusted* OR = 9.25; 95% CI =3.16- 27.06) and IL-10 1082 A/G (adjusted* OR = 4.28; (95% CI =1.46- 12.56) was found to be in association with increased risk of psoriasis while as IL- 10 819 C/T (adjusted* OR= 1.60; (95% CI = 0.65-3.95) polymorphism does not show any significant association with the risk of psoriasis. HT7 GTC haplotype is associated with increased risk of psoriasis. Serum levels of IL-10 were found to be significantly low in patients, as compared to controls with a non-significant correlation between serum IL-10 level and psoriasis severity.

Conclusion: IL-10 polymorphism imparted significant risk towards the development of psoriasis in North Indian population. Highlighting the role of IL-10 cytokine in the pathogenesis of psoriasis will help in the development of psoriasis management.

Keywords: Psoriasis, IL-10 polymorphism, ARMS PCR, ELISA, pleiotropic, cytokine.
