Molecular genetic association of rs8099917 and rs1800795 polymorphisms in the progression of hepatitis Delta virus liver disease.

ABSTRACT:

Background

The relationship between viral infections and host factors holds high hopes for identifying the role of Interferon Lambda 3 (IFNL3) and Interleukin 6 (IL-6) polymorphisms in the development of Chronic Liver Disease (CLD) in patients infected with hepatitis Delta virus (HDV) in the Western Brazilian Amazon.

Methods

Cross-sectional study conducted with a cohort of 40 chronic HDV patients, 27 with CLD and 13 without evident liver damage. Biological samples from the participants were analyzed using the polymerase chain reaction (PCR) technique, followed by sequencing by the automated Sanger method.

Results

The rs8099917 T allele, from the IFNL3 gene, showed a higher frequency in both groups; however, it was not possible to establish an association with HDV infection [OR = 1.42 (0.42 - 4.75; p = 0.556 (95% CI). For IL-6, the rs1800795 G allele was superior to rs1800795 C. Analyzing both distributions in the studied groups, any association with HDV was absent (p > 0.05).

Conclusion

The results suggest that the rs8099917 T/G (IFNL3) and rs1800795 G/C (IL-6) polymorphisms are not associated with the evolution of HDV in the studied population.

Project description:BackgroundThis meta-analysis aimed to assess available evidence on possible associations of interleukin-28B polymorphisms rs8099917 and rs12979860 with development of hepatitis virus-related hepatocellular carcinoma (HCC).MethodsPubMed, EMBASE, Google Scholar, and the Chinese National Knowledge Infrastructure databases were systematically searched to identify relevant studies. Meta-analyses were performed to examine the association of interleukin-28B rs8099917 G/T and rs12979860 T/C polymorphisms with development of hepatitis virus-related HCC. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated.ResultsA total of ten studies involving 2,529 cases and 2,412 controls were included. The G-allele and GT genotype of rs8099917 were significantly associated with increased risk of hepatitis B virus (HBV)-related HCC (allelic model, OR 1.49, 95% CI 1.13-1.96, P=0.005; heterozygous model, OR 1.39, 95% CI 1.04-1.88, P=0.03). Conversely, the TT genotype was found to be significantly associated with lower risk of HBV-related HCC (dominant model, OR 0.68, 95% CI 0.51-0.91, P=0.01). Similar results were observed in the subgroup of Chinese patients and controls. In the pooled data set, the T-allele and TT genotype of rs12979860 showed a significant association with increased HCC risk (allelic model, OR 1.36, 95% CI 1.05-1.78, P=0.02; recessive model, OR 1.75, 95% CI 1.28-2.39, P=0.005; homozygous model, OR 1.99, 95% CI 1.41-2.80, P<0.001). Subgroup analysis based on ethnicity and etiology showed rs12979860 polymorphism to be significantly associated with HCC risk in Caucasians, especially hepatitis C virus-related HCC, according to all five genetic models. In contrast, only the TT genotype of rs12979860 was found to be significantly associated with increased risk of HBV-related HCC, especially in Asians.ConclusionThe G-allele of rs8099917 may confer elevated risk of HBV-related HCC, while the wild-type TT genotype may protect against the disease. The T-allele of rs12979860 may increase the risk of HCC, in Caucasians, especially hepatitis C virus-related HCC. The TT genotype of rs12979860 may confer increased risk of HBV-related HCC, especially in Asians. These conclusions should be verified in large, well-designed studies.
