文摘

Hepatitis C virus infectivity and replication efficiency appears to be dependent on the lipid content and organization of the plasma membrane of the host cell, as well as of the intracellular membranous web. As there is increasing awareness of a role played by the efflux pump ABCB1 (p-glycoprotein, P-gp) in lipid homeostasis, its function could be a determinant of chronic HCV infection. The aim of the present study was to examine and compare the distribution of common ABCB1 genotypes in patients with chronic HCV infection (n = 168), hyperlipidemic patients (n = 168) and a control group (n = 173), all from Greece.

Methods

Participants were genotyped for the ABCB12677G>T/A and 3435C>T polymorphisms with previously reported PCR-RFLP methods. Genotype and allele frequency distributions were compared between the three groups with the χ² test of independence.

Results

The ABCB1 2677GG (ancestral) genotypes were significantly over-represented in patients with chronic hepatitis C compared to controls (39.3% vs. 26.6%, p = 0.015 according to the dominant model). A similar result was obtained when hyperlipidemic patients were compared to controls (45.2% vs. 26.6%, p < 0.001 according to the dominant model). Comparison of ABCB1 3435C>T genotype and allele distributions provided similar but not as significant differences. Genotype and allele distributions for both ABCB12677G>T/A and 3435C>T were very similar between HCV patients and hyperlipidemic patients.

Conclusion

Our findings imply an influence of ABCB1 polymorphisms on HCV infectivity, possibly through an effect on lipid homeostasis.
