Opis:
Helicobacter pylori (H. pylori) jest jedną z naczęściej występujących infekcji, jest głównym czynnikiem w etiologii zapalenia żołądka, choroby wrzodowej i nowotworów żołądka. Przewlekle infekcje często występują u chorych na cukrzycę. Prowadzonych było wiele badań dla oceny zwiększonej podatności na infekcje H. pylori u chorych na cukrzycę i możliwej roli takiej infekcji w metabolicznej kontroli cukrzycy. Niektóre badania wskazują na zwiększone występowanie infekcji u chorych na cukrzycę i na wpływ na pogorszenie kontroli glikemii, podczas gdy inne nie wykazały korelacji pomiędzy infekcją H. pylori a metaboliczną kontrolą. Tylko nieliczne badania poświęcone były ocenie skuteczności leczenia infekcji H. pylori u chorych na cukrzycę. W większości z tych badań wynika, że standardowa antybiotykoterapia jest znamiennie mniej skuteczna u cukrzycowych pacjentów niż w grupach kontrolnych. Prawdopodobnie zmiany naczyniowe w ścianie żołądka redukują absorpcję antybiotyków. Obecność gastroparezy i częste stosowanie antybiotykoterapii w nawracających infekcjach bakteryjnych prowadzi do rozwoju oporności i może być jednym z mechanizmów tłumaczących to zjawisko. Niektóre badania wskazują, że infekcja H. pylori jest znamiennym i niezależnym czynnikiem promującym występowanie insulinooporności w dużej bezobjawowej populacji. Insulinooporność jest utajonym patofizjologicznym czynnikiem prowadzącym do miażdżycy i schorzeń naczyniowo-sercowych.
Helicobacter pylori (H. pylori), one of the most common chronic infections , is the main etiologic agent of gastritis, peptic ulcer and gastric cancer. Patients with diabetes mellitus are often affected by chronic infections. Many studies have evaluated the prevalence of H. pylori infection in diabetic patients and the possible role of this condition in their metabolic control. Some studies found a higher prevalence of the infection in diabetic patients and a reduced glycaemic control, while others did not support any correlation between metabolic control and H. pylori infection. There are only a few studies on the eradication rate of H. pylori in diabetic patients. Most of these papers concluded that standard antibiotic therapy allows a significantly lower H. pylori eradication rate in diabetic patients than is observed in control groups. Changes in the microvasculature of the stomach with a possible reduction of antibiotic absorption. The presence of gastroparesis and the frequent use of antibiotics for recurrent bacterial infections with the development of resistant and be some of the mechanisms underlying this phenomenon. Some studies found that H. pylori infection significantly and independently contributed to promoting insulin resistance in a large asymptomatic population. Insulin resistance is the pathophysiologic background of the atherosclerosis and cardiovascular diseases.

Opis:
Introduction: According to the World Health Organization, Helicobacter pylori infection affects 70–90% of adults in developing countries and 25–50% of adults from developed countries. Objectives: An assessment of the incidence of Helicobacter pylori infection among the household members of patients with positive urease test as well as determination of risk factors, symptoms and coexisting diseases. Material and methods: Study included 62 relatives of 32 patients with Helicobacter pylori infection, who were occupying the same household. Control group included 40 relatives of patients with negative urease test. All participants were subjected to Diago-HP serological testing and completed a questionnaire including 30 questions. Results: It was found that Helicobacter pylori infection is significantly more common among the household members of infected patients compared to the control group (37.1% vs. 18.4%, p < 0.001). The incidence of infections was 58.5% in the study population (patients and their relatives). Infected patients were older than the uninfected ones (51.1 ± 15.0 vs. 36.5 ± 18.6 years, p < 0.001), they more often reported difficulties in defecation (72.7% vs. 50.8%, p = 0.04) and a feeling of fullness in the upper abdomen (75.9% vs. 50.8%, p = 0.02). Type 2 diabetes significantly increased the risk of Helicobacter pylori infection (100% vs. 53.6%, p = 0.004). No relationship was found between accommodation, hygienic habits, drug use, diet or keeping pets. Conclusions: The incidence of Helicobacter pylori infection is significantly higher among the household members of infected patients. The infection is more common among elderly and diabetic patients.
Wstęp: Infekcja Helicobacter pylori według Światowej Organizacji Zdrowia występuje u 70–90% dorosłych w krajach rozwijających się i około 25–50% w krajach rozwiniętych. Cel pracy: Ocena występowania infekcji Helicobacter pylori wśród domowników pacjentów z dodatnim wynikiem testu ureazowego oraz określenie czynników ryzyka zakażenia, towarzyszących objawów i chorób współistniejących. Materiał i metody: Do badania włączono 62 krewnych 32 osób zakażonych Helicobacter pylori, zamieszkujących jedno gospodarstwo rodzinne. Grupę kontrolną stanowiło 40 krewnych osób z ujemnym wynikiem testu ureazowego. Badani zostali poddani testowi serologicznemu Diago-HP oraz odpowiedzieli na 30 pytań ankietowych. Wyniki: Stwierdzono istotnie częstsze występowanie infekcji Helicobacter pylori u domowników osoby zakażonej w porównaniu z grupą kontrolną (37,1% vs 18,4%, p < 0,001). W całej badanej populacji (pacjenci i ich krewni) częstość infekcji wyniosła 58,5%. Osoby zakażone były starsze niż niezakażone (51,1 ± 15,0 vs 36,5 ± 18,6 roku, p < 0,001), częściej zgłaszały zaburzenia wypróżniania (72,7% vs 50,8%, p = 0,04) i uczucie pełności w nadbrzuszu (75,9% vs 50,8%, p = 0,02). Cukrzyca typu 2 znamiennie zwiększała ryzyko infekcji Helicobacter pylori (100% vs 53,6%, p = 0,004). Nie stwierdzono związku infekcji z miejscem zamieszkania, nawykami higienicznymi, stosowanymi używkami, dietą i posiadaniem zwierząt domowych. Wnioski: Zapadalność na infekcję Helicobacter pylori jest istotnie wyższa wśród domowników osób zakażonych. Zakażenie częściej występuje u osób w starszym wieku i chorujących na cukrzycę.

Purpose: To evaluate the hypothesis that vitamin C improves the efficacy of Helicobacter pylori eradication in smokers when combined with pantoprazole, amoxicillin, and clarithromycin. Materials and methods: The study completed 90 subjects of 98 enrolled, 58 smokers 32 nonsmokers. Helicobacter pylori status was determined by two methods, CLO test, and histology. Vitamin C (500 mg) was administered three times daily. The patients were considered as cured of H. pylori if the CLO test result and histology were negative 4 weeks after completion of eradication therapy. Results: Smokers had lower effectiveness of eradication therapy than non-smokers and the administration of vitamin C had not affected the outcome of eradication therapy. Conclusions: Vitamin C (500 mg tid) does not improve the eradication therapy when pantoprazole, amoxicillin, and clarithromycin were used.

Opis:
Helicobacter pylori is an etiological agent of chronic gastritis, gastric and duodenal ulcers and gastric cancers. The use of an appropriate animal model for experimental studies on the pathogenesis of H. pylori infections is necessary due to the chronic character of such infections and difficulties in identifying their early stage in humans. The aim of this study was to develop a guinea pig model of H. pylori infection and identify its microbiological, histological, serological and molecular determinants. Guinea pigs were inoculated per os with H. pylori strains: CCUG 17874 or ATCC 700312, both producing vacuolating cytotoxin A (VacA) and cytotoxin associated gene A (CagA) protein, suspended in Brucella broth with fetal calf serum (FCS) and Skirrow supplement of antibiotics. To determine H. pylori colonization, 7 and 28 days after the challenge, a panel of diagnostic methods was used. It included culturing of microorganisms from the gastric tissue, histopathological analysis of gastric sections, stained by Mayer,s haematoxylin and eosin to assess inflammatory response, by Giemsa as well as Warthin-Starry silver staining to visualise Helicobacter-like organisms (HLO) and with anti-Ki-67 antigen to assess epithelial cell proliferation. H. pylori infection was also confirmed by polymerase chain reactions (PCR) for detection in gastric tissue of ureC and cagA genes and by serological assessment of H. pylori antigens in faeces. This study showed the usefulness of microbiological, histological, immunological and molecular methods for the detection of persistent H. pylori infections in guinea pigs, which could be an appropriate model for studying H. pylori pathogenesis and the related immune response against these microbes.

Opis:
Purpose: To investigate, whether the test documenting the presence of Helicobacter pylori (H. pylori) antigens in the gastric mucosa may be used as diagnostic test. Materials and methods: Mucosal specimens taken from eighty-three patients during gastroscopic examination were subjected to rapid urease test (CLO test), histology, and H. pylori culture. The same biopsy specimens that had been evaluated in the CLO test or collected into the transport medium for bacterial culture were used to detect H. pylori antigens. An amplified immunoassay for the detection of H. pylori antigens in stool was used for gastric mucosa specimens. The sensitivity and specificity of the H. pylori antigen test were evaluated in relation to the results of each verifying test (CLO test, histology, culture) separately and to all 3 tests analysed together. Results: The sensitivity and specificity of the H. pylori antigen test in relation to the CLO test, histological examination, and H. pylori culture were 85.4% and 90.5%, 76.1% and 83.4%, and 90.7% and 90.0% for specimens taken for the CLO test and 90.0% and 82.0%, 78.0% and 81.0%, and 93.0% and 88.0% for specimens taken for bacterial culture, respectively. The sensitivity and specificity of the antigen test in relation to all 3 verifying tests analysed together were 91.3% and 97.3% for specimens taken for the CLO test, and 91.7% and 97.1% for specimens taken for bacterial culture, respectively. Conclusions: H. pylori antigen test in gastric mucosa specimens may be a sufficiently reliable source of information about stomach infection.

Opis:
Helicobacter pylori infection is common. The World Health Organization estimates that about 70% of people in developing countries and 30% in developed countries are infected with this bacterium. The infection spreads through personal contacts via an oral-oral, gastro-oral and faecal-oral route of transmission. Helicobacter pylori infection is asymptomatic in 80–90% of cases. Both invasive and non-invasive methods are used in the diagnosis of this infection. The choice of the method depends on the current clinical condition and the necessity to perform endoscopy of the upper gastrointestinal tract. Since the incidence and prevalence of Helicobacter pylori infection are high, H. pylori detection tests should be performed only when eradication therapy is planned. According to the guidelines of the Working Group of the Polish Society of Gastroenterology, eradication treatment involves a multidrug therapy with proton pump inhibitors, antibiotics and bismuth citrate. All of these drugs should be used for a period of 10–14 days. Clarithromycin should not be used as the first choice treatment because of increasing resistance in Poland. A breath test is an optimal way to evaluate the effectiveness of the antibacterial therapy but is rarely performed due to high price and low availability. Serology tests are available and cheap, but are not suitable to assess the efficacy of eradication. Helicobacter pylori antigen detection in stool is therefore important in the diagnosis. The test is not very expensive, available and characterised by very high sensitivity and specificity of up to 90%.
Zakażenie Helicobacter pylori jest powszechne. Światowa Organizacja Zdrowia szacuje, że zainfekowanych tą bakterią jest około 70% ludzi w krajach rozwijających się i około 30% w krajach rozwiniętych. Zakażenie szerzy się przez kontakty międzyludzkie. Dochodzi do niego na drodze: oralno-oralnej, gastro-oralnej oraz fekalno-oralnej. W 80–90% przypadków infekcja H. pylori ma charakter bezobjawowy. W diagnostyce zakażenia tym drobnoustrojem stosuje się metody inwazyjne i nieinwazyjne. Wybór metody uwarunkowany jest aktualną sytuacją kliniczną oraz koniecznością wykonania badania endoskopowego górnego odcinka przewodu pokarmowego. Wobec znacznego rozpowszechnienia i dużej częstości rozpoznawania zakażenia H. pylori testy na obecność tej bakterii należy wykonywać tylko w sytuacji, gdy planowane jest włączenie odpowiedniego schematu leczenia eradykacyjnego. Zgodnie z wytycznymi Grupy Roboczej Polskiego Towarzystwa Gastroenterologii w leczeniu eradykacyjnym stosuje się schematy wielolekowe uwzględniające inhibitory pompy protonowej, antybiotyki i cytrynian bizmutu. Wszystkie wymienione leki powinny być stosowane przez okres 10–14 dni. Z uwagi na narastającą w Polsce oporność na klarytromycynę antybiotyk ten nie powinien być wykorzystywany w leczeniu pierwszego wyboru. Optymalną ocenę skuteczności terapii przeciwbakteryjnej przeprowadza się na podstawie testu oddechowego, lecz z powodu ceny i dość trudnej dostępności nie jest to podstawowe narzędzie diagnostyczne. Z kolei dostępne dość szeroko i niezbyt drogie testy serologiczne nie nadają się do oceny skuteczności eradykacji. Na uwagę zasługuje więc oznaczanie antygenu H. pylori w kale, będące niezbyt drogim badaniem, dostępnym, charakteryzującym się wysoką czułością i swoistością, sięgającymi 90%.

Opis:
Erysipelas is an acute, erythematous, rapidly spreading skin infection, usually caused by beta-haemolytic group A Streptococcus bacteria. The disease is usually located on the legs and toes, less frequently on the face. One of the predisposing factors for the development of erysipelas are coexisting infections. The aim of the work was to attempt to determine whether there was any connection between the atypical course of erysipelas and Helicobacter pylori infection in a 47-year-old female patient. The patient had a history of treatment for chronic otitis media with effusion and recurring abdominal pain. The current disease started abruptly with fever, erythematous skin lesion located on the right cheek and severe pain in the right ear. After a few days, the facial erythema got worse, oedema appeared on the right side of the face and redness, oedema and pain in the auricle could be observed. After examinations by an ENT specialist and a dermatologist, erysipelas of the face, auricle and external auditory meatus was diagnosed. The diagnosis was confirmed by bacteriological examination. As a result of antibiotic therapy skin lesions subsided and the patient’s general condition improved. As the dyspeptic symptoms exacerbated, a diagnostic test was performed and a coexisting Helicobacter pylori infection was diagnosed. The overall clinical picture and data obtained from medical literature suggest that the coexisting Helicobacter pylori infection could have contributed to both the chronic otitis media with effusion and atypical course of erysipelas. According to medical literature, in the case of patients with dyspeptic symptoms, Helicobacter pylori bacteria can be transferred from the lining of the stomach upwards to the oral cavity, middle ear and paranasal sinuses. Kariya et al. in their review of original work suggested that Helicobacter pylori may contribute to the exacerbation of an existing inflammation in the middle ear, which is a microaerophilic environment required for this bacteria to grow. In conclusion, it seems that constant stimulation of the immune system by Helicobacter pylori could have caused the system to become dysregulated and weakened, which probably accounted for the atypical course of erysipelas in the patient described.
Róża jest ostrą rumieniową, gwałtownie szerzącą się infekcją skóry, najczęściej powodowaną przez paciorkowce beta-hemolizujące grupy A. Choroba lokalizuje się zazwyczaj na kończynach dolnych, rzadziej na twarzy. Jednym z czynników predysponujących do rozwoju róży są współistniejące zakażenia. Celem pracy była próba odpowiedzi na pytanie, czy istnieje związek pomiędzy nietypowym przebiegiem róży a zakażeniem Helicobacter pylori u 47-letniej pacjentki. W wywiadzie chora była leczona z powodu przewlekłego wysiękowego zapalenia ucha środkowego oraz nawracających bólów brzucha. Obecna choroba rozpoczęła się nagle gorączką, zmianą rumieniową zlokalizowaną na skórze prawego policzka i silnym bólem ucha prawego. Po kilku dniach nasilił się rumień twarzy, a także pojawiły się obrzęk prawostronny twarzy oraz zaczerwienienie, obrzęk i bolesność małżowiny usznej. Po konsultacji laryngologicznej i dermatologicznej rozpoznano różę twarzy, małżowiny usznej oraz przewodu słuchowego zewnętrznego. Rozpoznanie potwierdzono badaniem bakteriologicznym. W wyniku zastosowanej antybiotykoterapii uzyskano ustąpienie zmian skórnych i poprawę stanu ogólnego. Ze względu na nasilenie objawów dyspeptycznych po wykonaniu testu diagnostycznego rozpoznano współistniejące zakażenie Helicobacter pylori. Całokształt obrazu klinicznego oraz dane z piśmiennictwa sugerują, że współwystępująca infekcja Helicobacter pylori mogła sprzyjać zarówno przewlekłemu wysiękowemu zapaleniu ucha środkowego, jak i nietypowemu przebiegowi róży. Według doniesień z piśmiennictwa u pacjentów z objawami dyspeptycznymi bakterie Helicobacter pylori mogą zostać przeniesione z błony śluzowej żołądka drogą wstępującą do jamy ustnej, a także ucha środkowego i zatok przynosowych. Kariya i wsp., dokonując przeglądu prac oryginalnych, stwierdzili, że Helicobacter pylori może przyczyniać się do nasilenia istniejącego procesu zapalnego w uchu środkowym, stanowiącym środowisko mikroaerofilne, niezbędne do wzrostu tej bakterii. Podsumowując, wydaje się, że ciągła stymulacja układu odpornościowego przez Helicobacter pylori mogła prowadzić do dysregulacji i osłabienia układu immunologicznego, co prawdopodobnie wpłynęło na nietypowy przebieg róży u opisywanej pacjentki.

Opis:
Helicobacter pylori is a Gram-negative, spiral bacterium capable of colonizing the gastric mucosa. Infections caused by this microorganism often lead to the development of various gastrointestinal complaints. Simultaneous human colonization by H. pylori and intestinal parasites is a common phenomenon. Moreover, the two groups of pathogens share the similar predisposing factors. The presence of parasites together with H. pylori can significantly influence the modulation of the host immune response. During H. pylori infection, strong polarization of Th1 cells is observed. The presence of protozoa, also contributing to the recruitment of Th1 cells, may well aggravate this response and exacerbate gastric mucosal damage. In contrast, intestinal helminth infection is associated with the polarization of lymphocytes towards Th2; their presence enhances the regenerative processes within the digestive tract and lowers the host overresponse. A literature review suggests that co-infection with intestinal helminths may serve as a buffering mechanism against the effects of H. pylori and/or protozoan infection, alleviating the Th1-dependent response and protecting against inflammations within the gastrointestinal tract.

Opis:
Purpose: The role of Helicobacter pylori (Hp) in the development of gastroesophageal reflux disease (GERD) remains disputable. This study was planned to determine clinical-epidemic correlations between reflux esophagitis (RE) and Hp in older children. Materials and methods: 308 children with RE and 418 patients with chronic gastritis (CG) without RE between the ages of 12 and 18 were examined. Hp was diagnosed by histological (Giemsa and hematoxylin-eosin stain, with evaluation of dissemination grade) and rapid urease test. Subjective symptoms (heartburn, abdominal pain, other dyspeptic complaints) were analyzed by questionnaire. Results: Hp infection was found in 44.5% of children with RE (no difference in patients without RE), and it does not increase the erosive esophageal defects risk. Clinical symptoms are not connected to this infection in examined patients. The frequency of Hp infection decreases with the disease duration increase. Conclusion: The development of RE is not connected with Hp, but the disease course has certain peculiarities in the conditions of Hp infection.

Opis:
Helicobacter pylori (H. pylori) bacteria are human pathogens causing symptomatic gastritis, peptic ulcer or gastric cancer. Little is known about the kinetics of immune responses in H. pylori infected patients because the initial moment of infection has not been identified. Various animal models are used to investigate the immune processes related to H. pylori infection. In this study we checked whether H. pylori infection in guinea pigs, mimicking natural H. pylori infection in humans, resulted in the development of specific immune responses to H. pylori antigens by measuring the proliferation of lymphocytes localized in mesenteric lymph nodes, spleen and peripheral blood. The maturity of macrophages and cytokines, delivered by monocyte-macrophage lineage or lymphocytes, were considered as mediators, which might influence the lymphocyte blastogenic response. The obtained results showed the activation of T cells localized in mesenteric lymph nodes by H. pylori antigens in H. pylori infected guinea pigs four weeks postinfection. The blastogenic activity of lymphocytes was shaped by their interaction with antigen presenting cells, which were present in the cell cultures during the whole culture period. Moreover, the balance between cytokines derived from adherent leukocytes including interleukin 8 - IL-8 as well as interferon gamma - IFN-γ, and transforming growth factor beta - TGF-β delivered by lymphocytes, was probably important for the successful proliferation of lymphocytes. The H. pylori specific lymphocytes were not propagated in peripheral blood and spleen of H. pylori infected animals. The modulation of immunocompetent cells by H. pylori antigens or their different distribution cannot be excluded.

Purpose:It is expected that H. pylori residing outside the stomach influences the results of the stool test. The aim of the study was to investigate the occurrence of H. pylori antigens in dental plaque and feces of the patients with H. pylori infected and non-infected stomachs.Materials and methods: The study was conducted in 188 dentate patients, 107 with H. pylori infected and 81 non-infected stomachs. Stomach infection with H. pylori was evaluated with CLO test, histology and culture. The stomach was classified as infected if at least two of three tests (CLO test, culture, histology) were positive and as non-infected if all three tests were negative. Dental plaque was taken only from the natural teeth. On the day of the gastroscopic examination or on the next two days a stool sample was collected for H. pylori antigens testing. H. pylori antigens in dental plaque and feces were determined by immunological method.Results:In 60.8% of subjects with an infected stomach, H. pylori antigens were present both in the dental plaque and feces, in 37.4% in feces only, in 0.9% only in the dental plaque, and in 0.9% neither in the dental plaque nor feces. In 46.9% of subjects with a non-infected stomach, H. pylori antigens were found neither in the dental plaque nor feces, in 24.7% both in the dental plaque and feces, in 23.5% only in the dental plaque, and in 4,9% only in feces.Conclusions: There is a weak association between the occurrence of H. pylori antigens in feces and the dental plaque, and also between the occurrence of the antigens in the dental plaque and stomach infection.

Short peptides resembling the Helicobacter pylori urease antigen (UreB F8 Ser-Ile-Lys-Glu-Asp-Val-Gln-Phe) with deleted aspartic acid and glutamic acid residues, anchored through a triazine linker via the N-terminal moiety to cellulose plate were prepared. The peptides were used for binding of antibodies from sera of patients with medically confirmed atherosclerosis. Recognition of the peptides was also tested with anti-Jack beans urease antibodies. The important role of a Gly-Gly spacer separating the peptides from the cellulose support was shown. Different patterns of binding of antibodies from H. pylori infected patients and anti-Jack bean urease antibodies were observed only in the case of pentapeptides. The peptide Gly-Gly-Leu-Val-Phe-Lys-Thr was recognized by most of the tested sera.

Opis:
Helicobacter pylori (H.pylori) is an infective agent and the main resourceful factor of chronic, active ot type B gastritis, peptic and duodenal ulcer, gastric carcinoma and mucosa-associated lymphoid tumors. Nowadays, pharmological treatment of H. pylori infections attract attention beside antibiotic treatment. The aim of this study is to analyse the chemical composition of the essential oils of Thymus capitatus and the antimicrobial activity against H. pylori. Aerial parts of wild growing plant materials were collected during flowering stage from three different locations. Essential oil composition analyses were performed simultaneously by GC-FID and GC-MS systems. The antimicrobial activity of the essential oil were tested by broth dilution method. The thymol percentage was determined as more than half of the essential oil composition of Thymus capitatus-Yedidalga (51.9%) and Thymus capitatus –Yıldırım (57.1%); however, the composition of thymol was 47.2% followed by 15.1% (p-cymene), 10.0% (-terpinene) and 5.7% (carvacrol) for Thymus capitatus-Boğaz/Girne.The essential oil from Thymus capitatus- Boğaz/Girne showed the lowest MIC and MBC values and the strongest bactericidal activity against H. pylori compared to the other tested essential oils. Bactericidal efficacy of essential oil of Thymus capitatus on H. pylori could have been affected due to the varied rates of major compounds. Thymus capitatus essential oil could be an alternative way for the treatment of H. pylori infections.

Opis:
Colonization of gastric tissue in humans by H. pylori Gram-negative bacteria initiates gastric and duodenal ulcers and even gastric cancers. Infections promote inflammation and damage to gastric epithelium which might be followed by the impairment of its barrier function. The role of H. pylori components in these processes has not been specified. H. pylori cytotoxicity may potentially increase in the milieu of anti-inflammatory drugs including acetylsalicylic acid (ASA). The lipid transport-associated molecule such as low density lipoprotein (LDL), which is a classic risk factor of coronary heart disease (CHD) and 7-ketocholesterol (7-kCh) a product of cholesterol oxidation, which may occur during the oxidative stress in LDL could also be considered as pro-inflammatory. The aim of this study was to evaluate the cytotoxicity of H. pylori antigens, ASA, LDL and 7-kCh towards Kato III gastric epithelial cells, on the basis of the cell ability to reduce tetrazolium salt (MTT) and morphology of cell nuclei assessed by 4',6-diamidino-2-phenylindole (DAPI) staining. Kato III cells were stimulated for 24 h, at 37°C and 5% CO2, with H. pylori antigens: cytotoxin associated gene A (CagA) protein, the urease A subunit (UreA), lipopolysaccharide (LPS) and ASA, LDL or 7-kCh. H. pylori LPS, ASA, LDL and 7-kCh, but not H. pylori glycine acid extract (GE), demonstrated cytotoxicity against Kato III cells, which was related to a diminished percentage of MTT reducing cells and to an increased cell population with the signs of DNA damage. The results suggest that damage to gastric epithelial cells can be induced independently by H. pylori antigens, ASA and endogenous lipid transport-associated molecules. During H. pylori infection in vivo, especially in CHD patients, synergistic or antagonistic interactions between these factors might possibly influence the disease course. Further study is necessary to explain these potential effects.

Opis:
In the recent years one of the common causes of cancer related deaths in humans is associated with the development of gastric carcinoma leading to gastric cancer. It had long before reported that the potent agent that is intimately related with the gastric cancer is the infection of the bacterium Helicobacter pylori (H. pylori). H. pylori infection in humans is characterised by the development of acute peptic ulcers which creates a lots of gastroenterological symptoms. Co-existence of H. pylori in the human gastric environment is well adapted by the pathogen by evading the immune responses of the host. Gastric biopsy in patients suffering from H. pylori infection reported the development of gastric lesions having the chance to proceed towards development gastric cancer. Recently it was reported that eradication of the H. pylori colonization is not possible even after continued current antibiotic treatment over long periods and even combined regimes are unsuccessful.Moreover alterations of the genetic background of the host gastric cells were also reported along with infection of H. pylori, the primary concern for the evolution of the genetically transformed cells which is the hallmark for the development of malignancy. Clinical studies have reported the limited efficacy in decreasing the incidence of gastric carcinoma even after the eradication therapy has been completed for the bacterial colonization. Research based on the biopsy specimens obtained from conventional gastric endoscopy of affected patients has revealed some genetic or epigenetic alterations in the gastric mucosa. The cause of concern to human life lies in the fact that the number of sporadic cases of primary or metachronous gastric carcinoma has increased after successful eradication.The purpose of the present review is to assess the current status of the research based on the concept of development of gastric carcinoma in association with H. pylori infection in humans and to throw some light in the remedial measures against the pathogen which is a chronic burden in the well-being of the human society.

Opis:
Gastric cancer with the annual mortality of 700 000 is the second cause of death in the world. Iran with the annual incidence of 37 in 100 000 is among areas with high risk of gastric cancer. In Iran, Khuzestan Province with the annual incidence of 10 -15 in 100 000 is among areas with moderate risk. The role of Helicobacter pylori infection in distal gastric cancer as one of the most important risk factors of gastric ulcer has been proved but its role in proximal gastric cancer is controversial. In recent decades, the incidence of proximal cancers has increased. The aim of the study was to survey the relative frequency of Helicobacter pylori infection in the people with proximal cancer and to compare it with this infection frequency in the distal cancer. Material and methods. Relative frequency of Helicobacter pylori infection was surveyed by pathology tests and biopsy gastric mucosa sample staining with H&E in the patients with proximal and distal gastric ulcer whose cancers were proved by pathology method and also in the people who were healthy in terms of a gastric cancer. Data were statistically analyzed by frequency tables and chi square test. Results. One hundred and seventeen people entered the study. Among 32 patients with the proximal cancer, 21 people were with the positive Helicobacter pylori (65.6%) and 11 people (34.4%) were with the negative Helicobacter pylori (p<0.01). Among 30 patients with the distal cancer, 26 people were with positive Helicobacter pylori (86.7%) and four people were with negative Helicobacter pylori (13.3%) (p<0.01); 55 people were without the cancer, which among them, 40 people were with the positive Helicobacter pylori (72.7%); and 15 people were with the negative Helicobacter pylori (37.7%) (p<0.01). In comparison of the frequency of Helicobacter pylori infection in the patients with the proximal cancer, a weak significant difference exists (p = 0.053). Comparing the frequency of Helicobacter pylori infection in the patients with the gastric cancer and people without the cancer, no significant difference existed (p = 0.703). Conclusion. A weak significant difference existed between the frequency of Helicobacter pylori infection in patients with the proximal gastric cancer and the frequency of these infections in the patients with the distal cancer. So, eradicating Helicobacter pylori infection can be effective in preventing the distal gastric cancers in addition to preventing the proximal gastric cancers.

Background. The occurrence of clarithromycin resistance among Helicobacter pylori strains is a major cause of the treatment failure. Resistance to this drug is conferred by point mutations in 23S rRNA gene and the most prevalent mutations are A2143G and A2142G. The aim of the study was to evaluate the occurrence of A2143G and A2142G mutations in a group of H. pylori strains resistant to clarithromycin. Materials and Methods. The study included 21 clarithromycin-resistant H. pylori strains collected between 2006 and 2009 in southern Poland. Resistance to clarithromycin was quantitatively tested with the E-test to determine the minimal inhibitory concentration (MIC value). The point mutations of H. pylori isolates were detected by PCR followed by RFLP analysis. Results. The MIC values for clarithromycin for the analyzed strains ranged from 1.5 mg/L to 64 mg/L. Nine H. pylori strains exhibited A2143G mutation and A2142G mutation was found in 9 isolates as well. The results of RFLP analysis of 3 clarithromycin-resistant strains were negative for both mutations. The average MIC values for A2143G and A2142G mutants were 6 and 30 mg/L, respectively. Conclusions. Frequencies of A2143G and A2142G mutations were the same in all isolates tested. Strains with A2143G mutation exhibited lower MIC values than A2142G mutants. Application of PCR-RFLP method for detection of clarithromycin resistance allows for better and more efficient management of H. pylori infections.

Helicobacter pylori – Gram-negative rod, discovered more than 30 years ago, has a proven influence on inflammation of gastric and duodenal mucosa. The worldwide prevalence of H. pylori infection in the human population is estimated at 50% and is considered to be one of the most frequent bacterial infections in people. Many studies suggest that infection takes place in the early childhood within the family. The gastric mucosa is its natural habitat. In last time more and more findings about existence of this bacteria in another places of gastrointestinal tract and correlation with many diseases, especially an inflammation of oral cavity. The percentage of H. pylori detectability in the oral cavity ranges from 0 to 100%. Thus, more studies aimed at final determination of the bacterium reservoir in the oral cavity seem to be necessary.

Purpose: The aim of this study was to evaluate the presence of H. pylori antigens in the oral cavity (dental plaque and saliva) of patients undergoing systemic eradication therapy. Materials and methods: The study was conducted in 49 subjects with H. pylori stomach infection. H. pylori antigens in dental plaque and saliva were evaluated with immunological method. Results: In subjects with initial H. pylori oral infection, the presence of H. pylori antigens in the oral cavity 6 weeks after successful or unsuccessful H. pylori eradication therapy in the stomach was 47.0% and 50.0%, respectively. In subjects without initial oral infection with H. pylori, the presence of H. pylori antigens in the oral cavity 6 weeks after successful and unsuccessful eradication therapy in the stomach was 30.0% and 20.0%, respectively. Conclusions: The immunological method detecting H. pylori antigens in the dental plaque and saliva cannot be recommended to evaluate the efficacy of H. pylori eradication in the oral cavity.
