Forty-four patients with chronic HBV and HCV were observed. Serum levels of interferon-gamma (IFN-gamma), interleukin-2 (IL-2), and soluble IL-2 receptor (IL-2r) were measured by enzyme immunoassay in 29 patients divided into 3 groups: group 1 (n = 9) with chronic HBV, group 2 (n = 9) with chronic HCV, and group 3 (n = 11) with mixed HBV + HCV infection. Control group consisted of 10 normal subjects without HBV, HCV, or HIV infection markers. The most informative of Th1 cytokines was IL-2r: its concentration was increased significantly (p < 0.01) in all patients with hepatitis B and/or C in comparison with the control. In addition, there was a trend to an increase in the mean concentrations of IL-2r from group 1 to groups 2 and 3. The concentrations of IFH-gamma and IL-2 did not differ significantly in the patients and controls. However, the concentrations of IFN-gamma were increased significantly (p < 0.01) in comparison with the control in 3 patients from group 1 and 4 patients from group 3 with more pronounced inflammation.

[Immune-regulating Th1- and Th2-cytokines in chronic infections caused by hepatitis B and C viruses].

The serum levels of Th1 (gamma-IFN and sIL-2r) and of Th2 (IL-10) cytokines were measured in 33 patients (23 males and 10 females, mean age 23.1 +/- 1.9) with chronic viral hepatitis (CVH) according to a disease etiology (6 patients with hepatitis B--CVHB, 15 patients with hepatitis C--CVHC, and 12 patients with a mixed form of chronic hepatitis B and C--HBV + HCV). Besides, the contents of the studied cytokines were compared with the traditional infection markers and the presence of viremia. The similar indices taken from 10 healthy persons served as controls. The concentration of gamma-IFN was found to be reliably higher (p < 0.05) in patients of all three groups (0.32 +/- 0.07, 0.34 +/- 0.09 and 0.25 +/- 0.06 pg/ml, respectively) regardless of a disease etiology and as compared with the control value (0.09 +/- 0.04) pg/ml). At the same time, the levels of gamma-IFN, sIL-2r and IL-10 (0.25 +/- 0.06 pg/ml, 166.5 +/- 31.3 IU/ml and 48.1 +/- 8.4 pg/ml, respectively) was found to be reliably (p < 0.05 and p < 0.01) higher, as compared to the controls (0.09 +/- 0.04, 57.1 +/- 5.6 and 10.8 +/- 7.8, respectively), only in patients with the mixed infection of hepatitis. Like in our previous study, a trend was established towards the growing mean values of the IL-r level from its lowest parameters in the group of CVHB patients towards its highest parameters in the group with the mixed hepatitis form. According to our data, the IL-2r level correlated reliably with the activity of AlAt (r = 0.452; p < 0.05), while the gamma-IFN content correlated reliably with the IL-10 concentration (r = 0.805; p < 0.05), and the gamma-IFN content correlated with the IL-10 concentration (r = 0.805; p < 0.01) irrespective of disease pathology.

[Prognostication of the outcome of surgical treatment of hemorrhagic strokes using a computer].

A new mathematical method is suggested for making the prognosis of the results of surgery for haemorrhagic strokes due to essential hypertension and atherosclerosis. Twenty-two signs characterizing the patient's state are fed into the computer trained on the basis of 124 case reports of patients, both surviving and dying after surgery. The computer operating in accordance with the "Kopa-3" programme works out a vital prognosis for both the medicamental and surgical treatment. The prognosis proved correct in 90% of the cases. The described method permits an objective determination of the indications for surgery in hemorrhagic stroke.
