[Evaluation of cerebrospinal fluid and plasma creatine kinase (CK) activity in patients with purulent, bacterial meningoencephalitis]. / Ocena aktywnósci kinazy kreatynowej (CK) w plynie mózgowo-rdzeniowym i w surowicy chorych z ropnymi, bakteryjnymi zapaleniami opon i mózgu.

The aim of the study was evaluation of usefulness of cerebrospinal fluid (CSF) creatine kinase (CK) activity assessment in diagnostics of purulent, bacterial meningoencephalitis in adults. The investigations were performed in 18 subjects. In all individuals CSF and plasma CK activity was estimated during the first 24 hours of hospitalization. Mean CSF CK activity in patients in very severe clinical state (group I) was 27,41 IU/L compared to 16,73 IU/L in subjects of group II with moderate and mild course of disease. The difference between mean CSF activities of this enzyme was statistically significant (p < 0,01). The obtained results indicate the usefulness of CSF CK activity assessment in estimation of severity of the patient's clinical state. The magnitude of this activity seems to be also helpful as prognostic marker in purulent, bacterial meningoencephalitis.

[Evaluation of cerebrospinal fluid and plasma lactate dehydrogenase activity in patients with purulent, bacterial meningoencephalitis]. / Ocenaaktywnosci dehydrogenazy mleczanowej (LDH) w plynie mózgowo-rdzeniowym i w surowicy chorych z ropnymi, bakteryjnymi zapaleniami opon i mózgu.

The aim of the study was evaluation of usefulness of cerebrospinal fluid (CSF) lactate dehydrogenase (LDH) activity assessment in diagnostics of purulent, bacterial meningoencephalitis in adults. The investigations were performed in 17 subjects. In all individuals CSF and plasma LDH activity was estimated during the first 24 hours of hospitalization. Mean CSF LDH activity in patients in very severe clinical state (group I) was 299,11 U/L compared to 163,67 U/L in subjects of group II with moderate and mild course of disease. The difference between mean CSF activities of this enzyme was statistically significant (p<0,001). The obtained results indicate the usefulness of CSF LDH activity assessment in estimation of severity of the patient's clinical state. The magnitude of this activity seems to be also helpful as prognostic marker in purulent, bacterial meningoencephalitis.

[Procalcitonin (PCT) concentration in cerebrospinal fluid and plasma of patients with purulent and lymphocytic meningoencephalitis--own observations]. / Prokalcytonina (PCT) w plynie mózgowo-rdzeniowym i w surowicy chorych z bakteryjnymi ropnymi i limfocytarnymi zapaleniami opon i mózgu u doroslych--obserwacje wlasne.

The aim of the study was assessment of usefulness of cerebrospinal fluid (CSF) and plasma procalcitonin concentration estimation in differential diagnosis of neuroinfections in adults. Examinations were carried out in 17 subjects with purulent, bacterial meningoencephalitis and in 16 patients with lymphocytic meningitis. In all individuals CSF and plasma PCT concentrations were assessed on the 1st day of hospitalization. In patients with purulent, bacterial meningoencephalitis mean CSF concentration was 0,63 ng/mL, mean plasma PCT concentration--9,97 ng/mL. Mean CSF PCT concentration in patients with lymphocytic meningitis was 0,23 ng/mL and mean plasma PCT concentration--0,27 ng/mL. Differences of mean PCT concentrations between both groups of patients were statistically significant: CSF--p<0,05 and plasma--p<0,01. Obtained results indicate usefulness of plasma PCT concentration estimation in differential diagnosis of neuroinfections in adults. Cerebrospinal fluid PCT concentration seems to be of lesser importance in differential diagnosis of neuroinfections, but value of this parameter often correlates with the severity of the clinical state of the patients and may be taken into consideration in prognosis of the course and outcome of the bacterial meningoencephalitis.

[Serum intercellular adhesion molecule ICAM-1 concentration in interferon alpha treated patients with chronic viral C hepatitis]. / Stezenie rozpuszczalnej formy czastki adhezyjnej ICAM-1 w surowicy chorych na przewlekle wirusowe zapalenie watroby typu C leczonych interferonem alpha.

Intercellular adhesion molecule is a protein regulating the inflammatory cells movement. An increase of ICAM-1 expression on hepatocytes and in serum has been observed in patients with chronic viral hepatitis. Interferon alpha treatment should lead to inflammatory response diminution and serum ICAM-1 concentration decrease. The aim of the study was the estimation of interferon alpha treatment influence on serum ICAM-1 concentration in patients with chronic viral C hepatitis. A group of 19 interferon alpha treated patients with chronic viral C hepatitis has been observed. ALT activity, the presence of HCV antibody and HCV-RNAas well as histological examination has been estimated in every patient. Patients have got 144 doses of interferon alpha in a schedule 5 MU three times a week. After three months of treatment control estimations have been conducted for initial evoluation of treatment efficacy. Differences in ALT activity have been observed between I and III trials. ICAM-1 serum concentration has decreased significantly from 1322 to 369 pg/ml, and differences in ICAM-1 serum concentration have been observed in all trials. Estimation of serum ICAM-1 concentration is an indirect parameter of attenuation of inflammatory reaction after interferon alpha treatment.
