The genetic association of cytokine genes, single nucleotide polymorphisms, and the incidence of liver cirrhosis in chronic hepatitis C Egyptian patients

The objective of this study were to evaluate the effect of proinflammatory cytokines (IL-18 − 607 C/A, rs 1946518; IL-18 − 137 G/C, rs 187283; INF-γ + 874 T/A, rs 240561), SNPs, and the anti-inflammatory cytokine (IL-10 + 1082 G/A, rs 1800896) SNPs on the risk of development of hepatic cirrhosis in Egyptian patients and to evaluate the combined effect of the polymorphic variants t hat show an interrelation with the risk of hepatic cirrhosis. The study included 63 chronic HCV patients. The patients were stratified into two groups. Group 1 consisted of 33 cirrhotic chronic hepatitis C patients while the second group consisted of 30 non-cirrhotic chronic hepatitis C patients tha t were taken as a control group. Genotyping of IFN-γ (+ 874 T/A) and IL-10 (− 1082 G/A) SNPs was performed by allele-specific PCR technique (AS-PCR). Genotyping of IL-18 (− 607 C/A) and IL-18 (− 137 G/C) SNPs was determined by PCR-RFLP technique. Analysis of IFN-γ (+ 874 T/A) SNP reveal ed that the T allele and the TT genotype were significantly higher in cirrhotic patients’ group compared to non-cirrhotic group (P <  0.001 andP = 0.004, respectively). Analysis of IL-10 (− 1082 G/A) SNP revealed that the A allele and AA genotype were significantly higher in the cirrhotic patients’ group (P = 0.001 andP = 0.047, respectively). Regression analysis revealed that IFN-γ Hi/IL-10 Lo combined genotypes were significantly higher in liver cirrhosis patients compared to non...
