Background & objectives: Interleukin (IL)-10, an anti-inflammatory Th2 cytokine, is one of the key coordinators of the inflammatory responses involved. The present study was designed to evaluate the impact of IL-10 (-819/-592) genotypes, haplotypes, mRNA and the protein levels with risk for hepatitis B virus (HBV) related hepatocellular carcinoma (HCC) development in India. Methods: A total of 390 subjects (145 controls, 62 inactive HBV-carriers, 64 chronic-active HBV patients, 60 HBV related cirrhotics and 59 HBV- HCC subjects) were enrolled in the study. Allele specific (AS)-PCR, ELISA and RT-PCR methods were used for assessing polymorphism, spontaneous blood levels and the mRNA expression, respectively of IL-10. Results: The study revealed that the CC/TA genotype acted as a risk factor for cirrhosis (OR a =2.02; P<0.05) and the subsequent HCC development (OR a =2.20; P<0.05), with controls as reference. However, no significant association was found between the two haplotypes (CC and TA) observed and HCC risk. Moreover, the IL-10 protein and mRNA levels in peripheral blood mono nuclear cells (PBMCs) showed a significant elevation as the disease progressed to cirrhosis. But, no variation was observed in the IL-10 levels in subjects with different IL-10 genotypes. Interpretation & conclusions: These preliminary results suggest a strong association of IL10 (-819/-592) with the HBV infection mediated disease progression, from inactive carrier state to malignancy, in Indian population.
