[Influence of interferon-alpha therapy on the count and function of T lymphocytes in children with chronic hepatitis C]. / Wplyw leczenia interferonem-alpha na liczbe i funkcje limfocytów T u dzieci chorych na przewlekle zapalenie watroby typu C.

This study aims to assess number and function of T lymphocytes in children with chronic hepatitis persistent C. The study included 60 children with chronic hepatitis C. Among this group 30 were treated with interferon-alpha (INF-alpha) during 6 months. Forty healthy children were included in the study as the control group. We examined subsets of blood lymphocytes T (CD3, CD4, CD8) and lymphocytes with expression of CD3/HLADR, CD3/CD25 antigens using monoclonal antibodies IMK plus and flow cytometry, at the beginning and after 6 months. After INF-alpha therapy a significant increase in subset of CD4 lymphocytes, significant decrease in CD8, increase in CD4/CD8 ratio and increase in lymphocytes with expression CD3/HLADR, CD3/CD25 receptors were observed. Differences in CD8 lymphocytes and CD4/CD8 ratio in the treated children were statistical higher in children with elimination HCV RNA. Applying INF-alpha in children with chronic hepatitis C stimulated immunological response by increasing subsets of CD4 lymphocytes, CD4/CD8 ratio and stimulated lymphocytes.

[Herpes simplex encephalitis in children]. / Opryszczkowe zapalenie mózgu u dzieci.

Clinical course of Herpes Simplex Encephalitis were shown in this paper. 24 children in the age of 4 to 15 were treated at Polish Mother's Memorial Hospital in years 1992-1994. Value of EEG, CT scan, NMR were underlined in early diagnostic and casual treatment of diseases. All children from this analysis group survived, only 8 demonstrated late complications: epileptic attacks (3), spastic tetraparesis (1), encephalopathy and mental disturbances (1). Positive results of treatment were connected with early diagnosis and early antiviral treatment which is very important in decreasing death rate and preventing permanent injury.
