Helicobacter pylori has been implicated in stimulation of immune system, development of autoimmune endocrinopathies as autoimmune thyroiditis (AT) and on other hand induction of immunosupresion activates gastric and extra-gastric diseases such as gastric ulcer or cancer. It causes persistent lifelong infection despite local and systemic immune response. Our results indicate that Helicobacter pylori might cause inhibition of the specific cellular immune response in Helicobacter pyloriinfected patients with or without autoimmune diseases such as AT. We cannot also declare the carcinogenic effect in oropharynx. However the association of any infection agents and cancerogenesis exists. The adherence of Helicobacter pylori expression and enlargement of benign lymphatic tissue and the high incidence of the DNA of Helicobacter pylori in laryngopharyngeal and oropharyngeal cancer is reality. LTT appears to be a good tool for detection of immune memory cellular response in patients with Helicobacter pylori infection and AT. All these complications of Helicobacter pylori infection can be abrogated by successful eradication of Helicobacter pylori., J. Astl, I. Šterzl., and Obsahuje bibliografii
Autoimmune thyropathies are frequently linked to many infections, such as Helicobacter pylori, which are also supposed to play a role in their pathogenesis. The aim of this study was to evaluate the relationships between thyroid and gastric autoimmunity and H. pylori infection on a large sample of Czech population (n=1621) by monitoring the autoantibodies against thyroglobulin (anti-Tg) and thyroid peroxidase (anti-TPO) and gastric parietal cell (anti-GPC, representing thyrogastric syndrome) in correlation with antibodies against Helicobacter pylori (anti-H. pylori) of classes IgG and IgA. The interrelation between autoantibodies and H. pylori antibodies was assessed by H. pylori seropositivity. In H. pylori seropositive persons as compared to seronegative irrespective of age and sex, a higher occurrence of anti-TPO (10.4 % vs. 5.8 %, p=0.001) and anti-GPC (6.1 % vs. 1.7 %, p<0.001) was found. Differences in anti-TPO occurrence were significant in both men (7.0 % vs. 3.3 %, p=0.03) and women (12.7 % vs. 8.0 %, p=0.02), differences in anti-GPC occurrence were significant only in women (7.2 % vs. 1.7 %, p<0.001). Results of this study support the idea of a connection between infection of H. pylori and the occurrence of anti-TPO autoantibodies representing thyroid autoimmunity and gastric parietal cells autoantibodies representing the thyrogastric syndrome., I.

První epidemiologickou studii nevyšetřené dyspepsie v České republice provedla naše skupina v roce 2001. V roce 2011 jsme provedli novou prospektivní multicentrickou studii stejnou metodikou. V 22 centrech bylo zařazeno 1 836 osob (ve věku 5–98 let). Celková prevalence dlouhodobou dyspepsie byla 12 %, a to 3,5 % u lidí ve věku 5–24 let, 18 % mezi 25–64letými a 15 % u lidí ≥ 65 let. Přestože v posledních 10 letech došlo k významnému poklesu prevalence infekce Helicobacter pylori, prevalence a sociodemografické determinanty dyspepsie se signifikantně nezměnily., Epidemiology of uninvestigated dyspepsia was studied in the Czech Republic for the first time in 2001. The aim of our current multi-centre prospective study was to evaluate dyspepsia using the same methods in a representative sample of general unselected population from the same geographical areas 10 years later. A total of 22 centres entered the study. A total of 1,836 subjects (aged 5–98 years) were enrolled. The overall prevalence of dyspepsia was 12 %; namely 3.5 % in subjects aged 5–24 years, 18 % among 25–64-year-old persons and 15 % in subjects ≥ 65 years. Despite the substantial decrease of Helicobacter pylori infection in the Czech Republic over the past 10 years, the prevalence and basic socio-demographic determinants of uninvestigated dyspepsia did not change significantly., and Stanislav Rejchrt, Ilona Koupil, Marcela Kopáčová, Miluška Škodová Fendrichová, Bohumil Seifert, Viktor Voříšek, Jana Špirková, Tomáš Douda, Ilja Tachecí, Jan Bureš
