The clinical role of blood coagulation and platelet receptors gene allelic variants in development of cryoglobulinemic vasculitis at chronic hepatitis C
Abstract
Aim of investigation. To estimate the clinical and prognostic value of carriage of various blood coagulation and platelet receptors gene allelic variants in development of cryoglobulinemic vasculitis at chronic hepatitis C (CHC). Material and methods. Original study included overall 200 patients with CHCs and liver cirrhosis in its outcome, who were divided into 3 groups: patients without cryoglobulinemia (CG, n=123), those with asymptomatic cryoglobulinemia (ACG, n=40) and with cryoglobulinemic vasculitis (CGV, n=37). Assessment of polymorphism of the studied genes was carried out by real-time polymerase chain reaction with melting curve analysis. Results. CGV patients in comparison to those with ACG had 4G mutant allele are significantly more frequent (odds ratio (OR): 4G=2,008) as well as genotypes 5G4G+4G4G (OR: 5G4G+4G4G=4,950) of the gene PAI-675 5G/4G, and in comparison to patients without CG - CC mutant genotype of the gene ITGB3 1565 T/C (р =0,047). The multifactor analysis at comparison of patients with CGV and without it revealed the quantity of mutant alleles of PAI-675 5G/4G and ITGB3 1565 T/C genes and infection duration as independent factors for vasculitis development, while at comparison of patients with CGV and ACG - only quantity of mutant alleles of these genes. Patients with CGV allele C and CC homozygosity of the gene ITGB3 1565 T/C is associated to presence of renal diseases, while allele C genotypes (TC+CC) of ITGB3 1565 T/C gene is associated with involvement of muscular and nervous system. Conclusion. Carriage of mutant genotypes of PAI-675 5G/4G and ITGB3 1565 T/C genes is a factor which allows to predict CGV development in CHC patients, and can determine clinical manifestations of the latter.
