Наличие генетических маркеров CAT свидетельствует об ускоренных темпах прогрессирования фиброза печени у больных хроническим гепатитом

Goal. To evaluate the genetic profi le of patients with chronic hepatitis C (CHC) by the CAT gene polymorphism in the region-262G/A (rs1001179), GPX4 in the region-718C/T (rs713041), IL28B in the region C/T (rs12979860) and VEGFA in the region- 634G/C (rs2010963) to analyze the association of the rate of progression of liver fi brosis with polymorphic genetic markers. Materials and methods. We examined 36 patients with CHC with a rapidly progressive rate of fi brosis (up to 10 years) and 56 patients with a slowly progressive course of the disease (more than 10 years). The study of single- nucleotide polymorphisms of genes was carried out by the method of polymerase chain reaction. Results. In the group with rapid progression of liver fi brosis, individuals with multiple risk alleles for the studied polymorphisms were more common, which confi rms the association of the risk of liver fi brosis progression with the genetic markers CAT in the region-262G/A (rs1001179) and GPX4 in the region-718C/T (rs713041) with their combined carrier. Among patients with rapid progression of fi brosis, a greater number of individuals had simultaneously 4–6 risk alleles in 27.5%, while patients with slow progression of the process only in 11% of cases. Conclusion. This set of genetic markers can be used as genetic testing of patients with liver fibrosis to determine the prognosis of the disease.
