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

Goal of the study is to reveal the particular features of hemostasis in patients with chronic hepatitis C in dynamics of natural course of disease. Materials and methods. The indices of hemostasis in 535 patients with chronic hepatitis C were assessed by the number of platelets, degree of their aggregation with the use of inductor of adenosine triphosphate and without it (spontaneous aggregation of platelets). Coagulative hemostasis was analyzed by the activated partial thromboplastin time, antitrombin III, prothrombin ratio, prothrombin time, fibrinogen concentration in plasma and international normalized ratio. Based on the number of Tr, typical for the disseminated intravascular coagulation syndrome, conditionally the patients were divided into 3 groups: I group - hypercoagulability; II - transient phase between hyper and hypocoagulation and III- hypocoagulation, which also included patients with liver cirrhosis. Results and discussion. Independent on the phase of disseminated intravascular coagulation syndrome, increase of aggregation of Tr with the growth of maximal amplitude was observed. The main part of studied indices of coagulative hemostasis indicated at the condition of hypocoagulation in patients with chronic hepatitis C - this is significant increase of activated partial thromboplastin time, prothrombin time, international normalized ratio and decrease of fibrinogen concentration in the studied groups by the phases of disseminated intravascular coagulation syndrome. Value of antitrombin III changed oppositely, it decreased, so that plasma hemostasis tends to the hypercoagulation. Conclusion. Under the chronic hepatitis C all phases of disseminated intravascular coagulation syndrome were observed with the disorder of thrombocytic coagulative hemostasis. There was followed up multidirectional change of hemostasis which obtained in the most cases character of delitescent course of disseminated intravascular coagulation syndrome.

Objective. To identify specific clinical and laboratory characteristics of patients with chronic hepatitis C (CHC) and severe interferon (IFN) system suppression. Patients and methods. This study was conducted at the Clinical Department of Infectious Pathology, Research Institute of Epidemiology, Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing. We enrolled and examined 76 patients with confirmed CHC aged 18 to 80 years who had been followed up for at least 3 years. We analyzed the level of IFN-producing T-lymphocytes, IFN status, serum levels of IFN-α, -γ and -λ depending on viral and biochemical activity, and genotype. In addition to that, we evaluated the association between the IFN system parameters and age, duration of infection, genotype, viral load, and stage of liver fibrosis. The control group comprised 30 healthy individuals who had no complaints and no clinical or laboratory changes at the time of examination. Results. We identified 3 grades of IFN system suppression: grade 1–moderate (in 21% of patients), grade 2–mild (inadequate) (in 47% of patients), and grade 3–severe (in 32% of patients). We analyzed clinical and laboratory characteristics of patients with grade 3 IFN system suppression and evaluated the IFN system depending on age, duration of infection, genotype, viral and biochemical activity. We found that severe IFN system suppression correlated with duration of infection, stage of liver fibrosis with a tendency to increased levels of T-lymphocytes expressing receptors for IFN-α and IFN-γ (CD118+, CD119+). Key words: chronic hepatitis C, genotype, interferon status

Duration Of Infection

Aim. To study the features of tear production in patients with chronic hepatitis C, depending on the duration of infection. Methods. 40 patients (80 eyes) with chronic hepatitis C infection (first group - 11 patients, chronic hepatitis C duration up to 3 years, second group - 10 patients, chronic hepatitis C duration 3 to 5 years, third group - 19 patients, chronic hepatitis C duration over 5 years). The control group consisted of 20 healthy subjects (40 eyes). All study subjects underwent standard ophthalmic examination, a set of clinical, epidemiological and laboratory studies; the level of total tear production was examined by the Schirmer’s test. Results. Eye pathologies were determined in patients with chronic hepatitis C. Total tear production in patients with chronic hepatitis C was 1.82±0.09 mm compared to 2.2±0.06 mm in the control group. At the early stages of chronic hepatitis C (duration up to 3 years) tear production has changed diversely: it increased in 27.2% of patients and decreased in 18.8% of patients. At the later stages of chronic hepatitis C (duration over 5 years) tear production increased only in 15.8% of patients and decreased in 52.6% of patients. Conclusion. In patients with chronic hepatitis C total tear production changes depending on the duration and the severity of infection, which should be considered in the diagnosis, monitoring and treatment of ophthalmic diseases in patients with chronic hepatitis C infection.
