Comparison of Helicobacter pylori genotypes obtained from the oropharynx and stomach of the same individuals - a pilot study.

Helicobacter pylori has been recently detected in the oral cavity and oropharynx. However, the role it plays in oral and oropharyngeal pathogenesis remains unclear. The virulence of H.

Lymphocyte proliferative response to Helicobacter pylori antigens in H. pylori-infected patients.

Helicobacter pylori (Hp) contributes to the development of gastric and extra-gastric diseases such as autoimmune thyroiditis (AT), and causes persistent life-long infection despite local and systemic immune response. We determined the specific cellular immune response to Hp antigens and PWM (control mitogen) in two groups of Hp infected patients--group A (n = 21), involving patients with autoimmune thyroiditis and group B (n = 13) of patients without AT--using modified lymphocyte transformation test before and after eradication therapy in comparison with healthy controls (group C, n = 15). Immune reactivity to the majority of Hp antigens (aHp, hHp, HpAg, CagA) was significantly lower in group B before eradication therapy in comparison with healthy Hp negative controls.

Helicobacter pylori isolated from patients with tonsillar cancer or tonsillitis chronica could be of different genotype compared to isolates from gastrointestinal tract.

Helicobacter pylori from patients with different diseases, including so-called autoimmune thyroiditis, chronic tonsillitis and tonsillar cancer, was isolated and cultured. It was identified according to the genotype using labeled hybridization probes complementary to six sequences of cagA and vacA genes. Different types of strains were found in isolates from gastrointestinal tract and patients suffering from thyroiditis.

[Faecal elastase I--its use in diagnosis of chronic pancreatitis].

Background: The diagnosis of chronic pancreatitis is based on the imaging methods. These imaging methods show the main morphological changes in the pancreatic ducts and its parenchyma, but they do not define the function of the pancreas. The aim of our study was Faecal Elastase I.
