摘 要:AIM: To correlate a genetic polymorphism of the low-density lipoprotein(LDL) receptor with antiviral responses in Egyptian chronic hepatitis C virus(HCV) ***: Our study included 657 HCV-infected patients with genotype 4 who received interferonbased combination therapy. Patients were divided into two groups based on their response to therapy: 356 were responders, and 301 were non-responders. Patients were compared to 160 healthy controls. All patients and controls underwent a thorough physical examination, measurement of body mass index(BMI) and the following laboratory tests: serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, albumin, total bilirubin, direct bilirubin, prothrombin time, prothrombin concentration, INR, complete blood count, serum creatinine, fasting blood sugar, HCV antibody, and hepatitis B surface antigen. All HCV patients were further subjected to the following laboratory tests: HCV-RNA using quantitative polymerase chain reaction(PCR), antinuclear antibodies, thyroid-stimulating hormone, an LDL receptor(LDLR) genotype study of LDLR exon8 c.1171GA and exon-10 c.1413GA using real-time PCR-based assays, abdominal ultrasonography, ultrasonographic-guided liver biopsy, and histopathological examination of liver biopsies. Correlations of LDL receptor polymorphisms with HAI, METAVIR score, presence of steatosis, and BMI were performed in all ***: There were no statistically significant differences in response rates between the different types of interferon used or LDLR exon10 c.1413GA. However, there was a significant difference in the frequency of the LDL receptor exon8 c.1171GA genotype between cases(AA: 25.9%, GA: 22.2%, GG: 51.9%) and controls(AA: 3.8%, GA: 53.1% and GG: 43.1%)(P A polymorphism between responders(AA: 3.6%, GA: 15.2%, GG: 81.2%) and nonresponders(AA: 52.2%, GA: 30.6%, GG: 17.
