    Streszczenie angielskie: Helicobacter pylori (Hp) is a common pathogen colonizing the a gastric mucosa, but some reports indicated that it may also be found in the oral cavity, which could serve as a reservoir of the bacteria and a source of gastric reinfection. Accordingly, we aimed to study whether the oral cavity, particularly gingival pockets, are colonized by Hp and whether it could be the source of gastric reinfection. We studied 329 patients with dyspeptic symptoms (257 with chronic gastritis, 15 with gastric ulcer. and 57 with duodenal ulcer). The [**13C]urea breath test (UBT), gastroscopy, and Hp culture from gastric biopsies were carried out, and material was collected from the oral cavity (gingival pocket) for bacteriological culture and genomic DNA studies. The serum was obtained for anti-Hp IgG and anti-CagA assays and saliva for anti-Hp IgA determination using the ELISA technique. bacteria in material from gingival pockets and biopsies from the corpus and antrum of stomach of 30 DU patients before and after Hp eradication were also examined by PCR technique, using primers specific for 16S rNA. All Hp-positive patients (276) were subjected to one week of triple therapy (omeprazole 2 x 20 mg twice a day, clarithromycin 2 = 500 mg twice a day, and metronidazole 2 x 500 mg twice a day). The measurements descrived above were then repeated at four weeks and six months. Bacterkilogical culture showed the prsence of Hp in the material from oral cavity in about 50 p.c. of patients, whereas UBT, used as a gold standard, revealed gastric Hp infection in about 84 p.c. of these patients...

    Streszczenie angielskie: Colorectal cancers (CRCs) are one of the most common forms of cancer in Poland and one of the leading causes of dearh. The tumors have been attributed to genetic, dietary, and other environmemtal factors, but recently factors such as gastrin have also been implicated in the carcinogenesis. The relationship between plasma amidated and nonamidated gastrin in CRCs is controversial. This study was designed to determine the plasma levels of progastrin and amidated gastrin in 50 CRC patients before and 3-6 months after removal of the tumor, to determine the tumor concentrations of these gastrin peptides and the level of expression for gastrin mRNA and gastrin/CCKb receptor mRNA, to examine the expression of cyclooxygenase COX-1 and COX-2 in mRNA in CRC tissue, and to compare the prevalence of Hp and its cytotoxic protein, CagA, and cytokines (TNFŕ, IL-1á, and IL-8) in CRCs, before and after removal of tumor. It was found that thwe CRC, its resection margin, and the plasma contained severalfold higher levels of progastrin than of amidated gastrins and that the removal of the CRC tumor resulted in a marked reduction in plasma progastrin level without a significant alteration in plasma levels of amidated gastrins. Both gastrin and CCKb-R mRNA were detected in the cancer tissue and resection margin by RT-PCR, and similary, COX-1 and COX-2 mRNA were expressed in these tissues of moast CRCs. The seroprevalence of Hp, especially that expressing CagA, and levels of IL-1á, but not other cytokines, were significantly higher in CRC patients than in 100 age-...

    Streszczenie angielskie: Zollinger-Ellison syndrome is a very rare disease caused by tumor with gastrin producing cells accompanied by hypergastrinemia leading to gastirc hypersecretion and peptic ulcers and their complications. Female case of gastrinoma (Zollinger-Ellison syndrome; Z-E) with a record of 38 yrs of survival. Acute gastro-duodenal ulcers started at 28 yr of age and Z-E was diagnosed by using gastrin assays. Basal and maximal acid outputs and ratio of basal/maximal outputs were away over normal limits. Because of ulcer recurrence and complications, patients was subjected to several gastric surgeries but refused total gastrectomy. She was also treataed with many H2-receptor (R) antagonists and proton-pump inhibitors (PPI), each new drug being initially highlyt effective but then showing declinig efficacy except when PPI, lansoprazole was used. The gastrin level rose in the course of disease from initial high value of 2000 pg/mL to the extreme 4500 ng/mL at present. During the last 2 yrs, metastasis mainly to liver developed and they were successfully treated by synthetic octapeptided derivative of somatostatin and, as a result, metastatis partly reduced and plasma gastrin drasticly decreased. Biopsy taken from liver metastasis showed the presence of typical gastrinoma cells with gastrin and chromogranin, while that from oxyntic mucosa revealed the ECL-cell hyperplasia with corcinoid tumors and unexpected gastric atrophy. This phenomenal case described in this article might be the new proven evidence needed by gastroenterologists to overturn the traditional treatemnt using total gastrectomy as a treatment of choice to the partial gastrectomy combined with proton pump inhibitors.

    Streszczenie angielskie: Helicobacter pylori (H. pylori) and nonsteroid anti-flammatory drugs (NSAID) are the most common pathogens in the gastroduodenal mucosa in animals and humans, but their relationship in ulcerogenesis has been little studied. Acording to some authors, H. pylori infections in humans does not act synergistically with NSAID on ulcer healing, therefore, there is no need to eradicate the germ. This notion is supported by the finding that the eradication of H. pylori does not affect NSAID-induced gastropatyhy treated with omeprazole and that H. pylori inferction induced a strong cyclooxygenase-2 expression resulting in excessive biosynthesis of gastroprotective prostaglandins, which should in turn counteract NSAID-induced gastropathy and heal existing ulcer. Other investigators claim that H. pylori infection acts synergistically with NSAID on ulcer development, therefore, H. pylori should be eradicated, particularly at the start of long-term NSAID therapy. Maastricht 2-2000 consensus also recommends eradication prior to NSAID treatment, but this eradication does not appear to accelerate ulcer healing or to prevent the recurrent ulcers in NSAID users. Our studies in almost 6000 dyspeptic patients undergoing upper endoscopy and [13C]-urea breath test (UBT) revealed that about 70 p.c. of these patients are H. pylori (+) and about 30.6 p.c. of these develop gastroduodenal ulcers. Of these ulcers, over 70 p.c. were H. pylori (+) positive, 12 p.c. NSAID (+), 8 p.c. both H. pylori (+) and NSAID (+), while 22 p.c. ulcers were H. pylori (-) and NSAID (-) or "idiopathic" ulcers...

    Streszczenie angielskie: Background: Hp and NSAID are considered as major pathogens in peptic ulcerations and their complications but little is konwn about the incidence of ulcaers and their complications following widespread use of Hp eradication. The aim of the study were: 1) to analyze incidence of ulcers and their complications, bleeding and perforations at time when the HP eradicaton has been used in ulcer therapy, and 2) to assess the impact of Hp infection and NSAID use on the incidence of ulcers and complications. Material/Methods: From 1996 to 2001, 381 patients with complications of peptic ulcers were admitted to the emergency surgery, including 273 patients with bleeding ulcers and 108 with perforations out of a sample of 6515 dyspeptic patients examined with upper endoscopy and 13C-urea breath test (UBT). Results: The rate of ulcer bleeding and perforations, remained relatively constant throughout the study period. NSAID use in that group increased form 15.8 p.c. in 1999 to 19.3 p.c. in 2001. The incidence of HP in patients with complications assessd by UBT or CLO was 76.7 p.c., while the incidence of Hp in 7920 patients ranged form 72.8 p.c. in 1996 to 53.8 p.c. in 2001. There were 1940 (29.7 p.c.) patients with duodenal and/or gastric ulcer diagnosed by upper gastroscopy. The decline in the prevalence of peptic ulcer from about 44 p.c. to 8 p.c. occurred over the same time. A slight increase in the number of ulcer resulting from NSAID use was observed so was the number of ulcers without Hp or NSAID (idiopathic). Conclusions: Despite decreased Hp prevalence, the incidence of ulcers complications remained unchanged probably due to increased use of NSAID and the appearance of idiopathic ulcers.

    Streszczenie polskie: Wprowadzenie: Podczas przebiegu zakażeń wywoływanych przez zlokalizowane w nabłonku żołądka pałęczki H. pylori może dochodzić do znaczne koncentracji antygenów tego drobnoustroju w kale. Taka hipoteza opiera się na przypuszczeniu o fekalno-oralnym modelu transmisji zakażenia. Sugeruje się, iż obecność antygenów H. pylori w kale może być wskaźnikiem aktualnego zakażenia tymi bakteriami natomiast ich zanik może świadczyć o skutecznej eradykacji drobnoustrojów. Cel pracy: Celem przeprowadzonych badań było porównanie skuteczności testu PP HpSA ze sktuecznością metod inwazyjnych: RUT, HLO lub nieinwazyjengo testu UBT i badania serologicznego (ELISA, IgG anty-EG), w diagnozowaniu zakażeń wywołwyanych przez H. pylori. Materiałi meotdy: W obecnie przeprowadzonych badaniach do wykrywania zakażeń wywoływanych przez H. pylori zastosowano nieinwazyjny, immunoenzymatyczny test Premier Platinum HpSA-PP HpSA (Meridian Diagnostics, Cincinnati, Ohio USA), przeznaczony do wykrywania antygenów tego drobnoustroju w kale. Test ten opiera się na aktywności poliklonalnych przeciwciał rozpoznających antygeny H. pylori. Wyniki testu PP HpSA odnoszono do wyników testów inwazyjnych: szybkiego testu ureazowego - RUT oraz badania histopatologicznego - HLO lub nieinwazyjengo testu oddechowego z użyciem mocznika znakowanego węglem 13C-UBT i badania serologicznego (ELISA), mającego na celu określenie występowania w surowicach osób badanych przeciwciał klasy IgG przeciwko antygenom ekstraktu glicynowego (EG) wzorcowego szczepu H. pylori CCUG 17874...

    Streszczenie angielskie: Background: Helicobacter pylori (Hp) and nonsteroidal anti-inflammatory drugs (NSAID) are the most common pathogens in the stomach, but their interaction on gastro-duodenal mucosa has been little studied. Hp infection in humans does not interfere with NSAID-induced gastric ulcer healing by omeprazole, therefore, there is no rationale to eradicate the germ under these conditions. Hp infection induces COX-2 expression resulting in excessive biosynthesis of gastroprotective prostaglandin (PG), which should in turn counteract NSAID-induced gastropathy and contribute to healing of existing ulcers. Some investigators claim that Hp infection acts synergistically with NSAID on ulcergenesis and propose that Hp should be eradicated, particularly at the onset of long-term NSAID therapy but this is the subject of controversy. Material and methods: Our studies on 6515 dyspeptic patients undergoing upper endoscopy and 13C-urea breath test (UBT) revealed that about 70 p.c. of these patients are Hp positive and 31 p.c. of them develop gastro-duodenal ulcers. Of these ulcers, 66 p.c. were Hp positive non NSAID users, 3 p.c. were Hp negative and NSAID users, 8 p.c. were both Hp positive and NSAID users, while 23 p.c. ulcers were both Hp and NSAID negative. An evidence was obtained for negative interaction between Hp infection and NSADI on risk of gastro-duodenal ulcers suggesting that Hp may attenuate the peptic ulcerogenesis. Conclusions: Our results support the concept that 1) the interaction between Hp infection ...

    Streszczenie angielskie: Background: Infection by Helicobacter pylori (Hp) has been linked to extradigestive pathologies including ischemic cerebral disease. The aim of our study was to assess the relationship between chronic Hp infection and ischemic stroke risk factors. Material/Methods: 80 patients (pts) aged 60 - 75 years with ischemic stroke confirmed by CT scans (group I) and 80 age- and gender-matched healthy controls (group II) were included into trial. Atherosclerotic plaques from 20 Hp positive pts were obtained at carotid endarterectomy for Hp DNA assessment by PCR. In all groups following parameters were determiend; 1) the prevalence of Hp infection using 13C-Urea Breath Test (UBT), 2) plasma anti-Hp and anti-CagA IgG and interleukin-8 (IL-8), and 3) palsma lipids and fibrinogen. Hp positive pts and controls received one-week anti-Hp therapy and after six months total cholesterol, low-density lipoprotein (LDL)-cholesterol, fibrinogen and IL-8 levels were re-examined. Results: Hp infection was detected by UBT in 83.75 p.c. of stroke pts but only in 65 p.c. of controls. DagA seropositivity was also significantly higher in stroke pts (57.5 p.c.) than in controls (33.75 p.c.). Plasma levels of cholesterol, LDL-cholesterol and fibrinogen as well as IL-8 were significantly higher in Hp positive subjects, especially in pats with ischemic stroke. Six months following successful anti-Hp therapy, the plasma levels of total cholesterol, LDL-cholesterol, fibrinogen and IL-8 were significantly lower than those in Hp positive stroke pts and contorls. Conclusions: Hp infection represents risk factor of ischemic stroke via an interaction of Hp cytotoxings of cytokines with atherosclerotic plaques in carotic arteries.
