[Von Willebrand factor and thrombomodulin as markers of endothelial cell functions in children with chronic viral hepatitis].

Introduction: Vascular endothelial cells play an important role in haemostasis. Similar to hepatocytes they synthesise many substances taking part in blood clotting and fibrinolysis.

Objective: The aim of the study was the evaluation of markers of endothelial cells: von Willebrand factor (vWf) and thrombomodulin (TM) in children with chronic viral hepatitis.

[Antithrombin III, protein C and protein S in children with chronic viral hepatitis B or C].

Abnormalities of blood coagulation are a major part of acute and chronic viral hepatitis. In this study antithrombin III, protein C and protein S were determined in 100 children with chronic hepatitis B or C infection (range age 3-17) according to degree of hepatic histological activity and fibrosis. There was no statistically significant correlation between levels of examined parameters in children with chronic viral hepatitis compared with those in control group and between the degree of hepatic histological activity and fibrosis and coagulation parameters.

[Prevalence of soya allergy in children with cow's milk allergy].

Unlabelled: Because of contradictory data about the prevalence of soya allergy in children recommendations for the use of the protein-based formulas are ambiguous. THE AIM of the study was to estimate the prevalence of soya allergy in children with IgE-associated cow's milk allergy.

Material: Ninety seven patients aged from six months to four years with personal history suggestive of food allergy with specific IgE to cow's milk protein attending the Department of Pediatrics, Allergology and Gastroenterology between 2000-2002 were studied.

[Flow cytometric analysis of peripheral blood lymphocytes in children with chronic gastroduodenitis with and without Helicobacter pylori infection].

The immune system plays an important role in chronic gastroduodenitis. A group of 70 children with chronic gastroduodenitis were subjected to examinations, including 42 children with H. pylori infection (group I) and 28 children without H.

[Delayed diagnosis of dermatitis herpetiformis as a silent form of coeliac disease--a case report].

We report a difficulty in the diagnosis of silent form of coeliac disease in adult first degree relative with enteral and parenteral symptoms. The aim of the report was to attract non-paediatrician's attention to more frequent occurrence of coeliac disease in adults.
