Activity an enzyme 5`-nucleotidase in patients with chronic hepatitis C

Aim of the study. To determine the activity of enzyme 5`-nucleotidase depending on the of disseminated intravascular coagulation syndrome phases and duration of infection period in patients with chronic hepatitis C. Materials and methods. 166 patients (92 men, 74 women) with chronic hepatitis C were under observation. Conditionally, all patients were devided into 3 groups, based on the number of Tr, according to the phases of hemostasis: I group - hypercoagulation with number Tr>350×109/l; II - transient phase - Tr from 350 to 200×109/l and III - hypocoagulation - Tr <200×109/l which included patients with liver cirrhosis of A class according to Child-Pugh. Enzyme 5`-nucleotidase was determined using Camdell method (1962) in modification of D.M. Zubairov and I.A. Andrushko (1987). Results. Activity of 5`-nucleotidase in phases of hypocoagulation in patients with liver cirrhosis of A class according Child-Pugh were higher than transient phase - and hypercoagulation correspondignly by 29%, p=0.000; 32%, p=0.001 and 5%, p=0.000; 8%, p=0.022. Reverse side of correlation dependence of activity of 5`-nucleotidase on the Tr level in patients in phase multidirectional shifts (r=-496646, p<0.05), and in condition of hypocoagulation (r=-0.591818, p<0.05). Level of 5`-nucleotidase was significantly higher in patients with a period of desease 11-15 and 16-25 years in comparison with a period up to 5 years respectfully by 29.1%, p=0.032; 63.2%, p=0.000. Reliable difference in activity of 5`-nucleotidase was observed between 6-10 years and 16-25 years of illness by 43.5%, p=0.005. Conclusion. In the natural course of chronic hepatitis C increase of 5`-nucleotidase is typical, especially expressed in the phase of hypocoagulation. Level of enzyme 5`-nucleotidase activity depends on the terms of infection with hepatitis C virus.
