Role of Helicobacter Pylori in Gastro-Intestinal Tract Disorders (Gitds) Among Patients in Kirkuk City, Iraq

ABSTRACT: In recent works Helicobacter pylori (H. pylori) become a significant criteria and essential diagnostic tool for studying the etiology of gastro-intestinal tract disorders (GITDs), for this purpose a total of stool samples were collected from 266 patients from both gender ,they were aging from below one year to over than 70 years. Their compliance with epi-gastric pain, diarrhea weigh loose and other disorders. Types of GITDS were detected and classified by the gastro-enterologists in two main Hospitals and from patients attending Private clinics and medical labs in Kirkuk city. H. pylori was detected form stool samples by using rapid lateral immune-chromatography assay (RLICA). GITDs involve, H. pylori positive distributed in 132 (49.62%), followed by 74 (27.81 % ), 59(22.18 %), 7(2.63 %), 3(1.12%) and 2(0.75 %) for irritable bowel diseases, inflammatory bowel diseases, peptic ulcer, ulcerative colitis and duodenal ulcers diseases respectively. Whereas 171, (64.28%) were positive for parasitic infection, P<0.05 .Moreover other 48, (18.04 %) stool samples were non-identified it's about from the described diseases. A total of132 (49.62 %) of H. pylori positive samples were distributed in 46(38.84 %) samples for IBD versus to 41(31.81 %) for IBS and 33(25%) were positive for parasitic infections, p <0.05. According to age; highest rate 10 (55.55 %) of H. pylori was recorded among patients aging from 61 to 70 years, whom they have IBD. Whereas 7 (70 %) have IBS within age group from 41 to 50 years, P <0.05. It can be that H. pylori participate with high rate in GITDs patients particularly IBD elderly patients.

Background: Helicobacter pylori and intestinal parasites are estimated to infect with high burden worldwide. However, their concomitant infections are poorly determined in industrialized countries, such as Italy. In this study we aim at describing the presence of H. pylori as well as the proportion of coinfections with intestinal parasites among subjects who attended a referral center for tropical diseases in Northern Italy. Methods: This was a case-control study. Screening for H. pylori and parasites was performed on stool samples of 93 adults from different geographical origin (Africa, Asia, South-America, East-Europe and Italy). H. pylori infection was examined by CLIA and its cagA positivity was determined by rtPCR. Intestinal parasites (i.e., protozoa and helminths) were examined by microscopy and rtPCR. Results: Sixty-one out of 93 patients (66%) were positive to H. pylori and 31 (33%) were cagA+. Among H. pylori positives, 45 (74%) had a concomitant infection. The coinfection H. pylori–Blastocystis was the most frequent one, followed by H. pylori–E. coli. Multivariable logistic regression showed that positivity to H. pylori was associated with having a coinfection. Conclusion: Our data suggested that H. pylori and intestinal parasitic infections are fairly common in subjects who attended a referral center for tropical diseases in Northern Italy. The high rate of H. pylori infection, and especially the positivity to the virulent cagA+, should be taken into consideration in subjects undergoing screening for parasitic infections.

Introduction: Helicobacter pylori eradication remains a problematic issue. We are in an urgent need for finding a treatment regimen that achieves eradication at a low cost and less side effect. Recent published results showing a high rate of resistance and with clarithromycin-based treatment regimens. The aim of the study was to compare moxifloxacin therapy and classic clarithromycin triple therapy in H. pylori eradication. Methods: This was a pilot study that enrolled 60 patients with helicobacter pylori associated gastritis. Diagnosis was done by assessment of H. pylori Ag in the stool. The patients were randomly assigned to receive either moxifloxacin based therapy (Group A), or clarithromycin based therapy (Group B) for two weeks. We stopped the treatment for another two weeks then reevaluation for cure was done. Results: 90 % of patients had negative H. pylori Ag in the stool after 2 weeks of stoppage of the treatment in group A versus 66.7 % in Group B. None of the patients in both groups had major side effects. Conclusion: Moxifloxacin-based therapy showed higher eradication power and less resistance when compared to clarithromycin triple therapy.

Background. Neglected tropical diseases continue to be one of the leading causes of morbidity and mortality in the developing world. Psychiatric patients are among groups at risk for parasitic infection although control and monitoring programs largely overlook this population. This study aimed at determining prevalence and factors associated with intestinal parasitic infection among patients admitted to a psychiatric facility.Method. The study followed cross-sectional design; all the residing patients that met the inclusion criteria were included in the survey. Stool samples were collected and examined by direct wet preparation and formol-ether concentration. Data were analyzed with STATA version 12.1; Chi-square test was computed to determine the level of significance atpvalue < 0.05.Results.Of all 233 patients who returned the stool samples, 29 (12.45%) screened were positive for an intestinal parasite. There was no significant association between parasite carriage and age, sex, or duration of hospital stay.Conclusion. The study shows that intestinal parasitic infection is common among patients in a psychiatric facility and highlights that parasitic infections that enter through skin penetration may be a more common mode of transmission than the oral route. Furthermore, the study underscores the need for surveillance and intervention programs to control and manage these infections.

We determined the incidence of gastric metaplasia in the duodenal bulb of duodenal ulcer patients and the Helicobacter pylori (H. pylori) infection rate at sites with gastric metaplasia. Biopsy of the duodenal bulb showed the presence of gastric metaplasia in 61 of 86 patients (71%) overall and in 18 of 47 patients (38.3%) who had gastrectomy at an early gastric cancer. The histological diagnosis of H. pylori infection showed good agreement (83.3%) with the result of the rapid urease test, indicating that H. pylori occurs in regions with gastric metaplasia. This finding suggests that H. pylori infects gastric metaplasia in the duodenal bulb, causing mucosal injury, which is then transformed into duodenal ulcers. The exact mechanism by which gastric metaplasia is caused is unknown, but it is believed to occur in the transitional zone in the duodenal mucosa.

Helicobacter pylori (H. pylori) has a role in the multifactorial etiology of peptic ulcer disease. A link between H. pylori infection and duodenal ulcer disease is now established. Other contributing factors and their interaction with the organism may initiate the ulcerative process. The fact that eradication of H. pylori infection leads to a long-term cure in the majority of duodenal ulcer patients and the fact that the prevalence of infection is higher in ulcer patients than in the normal population are cogent arguments in favor of it being the primary cause of the ulceration. This study was under taken at the Department of surgery, Narayana medical college, Nellore from January 2007 to July 2008. A total of 150 patients with duodenal ulcers, gastric ulcers, antral gastritis, gastric carcinoma and dyspepsia of any kind were studied. Maximum number of cases were in the age group of 31 years to 50 years among both sexes and number of cases gradually decreased after 50 years of age in males and females. Males were more in number and male to female ratio is (2.75:1) approximately 3:1.

Laboratory-based chemiluminescence immunoassays (CLIA) are widely used in clinical laboratories. Some years ago, a CLIA test was developed for the detection of Helicobacter pylori in stool samples, known as LIAISON H. pylori SA, but little information on its use has been reported. To evaluate the accuracy of the LIAISON H. pylori SA assay for diagnosing H. pylori infection prior to eradication treatment. Diagnostic reliability was evaluated in 252 untreated consecutive patients with dyspepsia. The gold standard for diagnosing H. pylori infection was defined as the concordance of the rapid urease test (RUT), histopathology and urea breath test (UBT). The CLIA assay was performed according to the manufacturer's instructions. Sensitivity, specificity, positive and negative predictive values, and 95% CIs were calculated. According to the gold standard selected, 121 patients were positive for H. pylori infection and 131 negative. LIAISON H. pylori SA had a sensitivity of 90.1% and a specificity of 92.4%, with positive and negative predictive values of 91.6% and 90.1%, respectively. The accuracy of the LIAISON H. pylori SA chemiluminescent diagnostic assay seems comparable to that of ELISA or the best-performing LFIAs. Its sensitivity and specificity, however, seem slightly lower than those of histology, RUT or UBT. The advantages of the assay are that it is cheap, automated, and minimally labor-intensive.

Bacterial Protein Synthesis

Helicobacter pylori colonizes the gastric epithelium of ∼50% of the world's population and plays a causative role in the development of gastric and duodenal ulcers. H. pylori is phagocytosed by mononuclear phagocytes, but the internalized bacteria are not killed and the reasons for this host defense defect are unclear. We now show using immunofluorescence and electron microscopy that H. pylori employs an unusual mechanism to avoid phagocytic killing: delayed entry followed by homotypic phagosome fusion. Unopsonized type I H. pylori bound readily to macrophages and were internalized into actin-rich phagosomes after a lag of ∼4 min. Although early (10 min) phagosomes contained single bacilli, H. pylori phagosomes coalesced over the next ∼2 h. The resulting “megasomes” contained multiple viable organisms and were stable for 24 h. Phagosome–phagosome fusion required bacterial protein synthesis and intact host microtubules, and both chloramphenicol and nocodazole increased killing of intracellular H. pylori. Type II strains of H. pylori are less virulent and lack the cag pathogenicity island. In contrast to type I strains, type II H. pylori were rapidly ingested and killed by macrophages and did not stimulate megasome formation. Collectively, our data suggest that megasome formation is an important feature of H. pylori pathogenesis.

SUMMARYPatients (454) referred for gastroscopy to the General Hospital of Athens were examined to determine (1) if non-secretors were over-represented among patients with ulcers and (2) is there was an association with ABO blood group or secretor status and carriage ofHelicobacter pylori.Compared with the local population, among patients with either gastric ulcer (51) or duodenal ulcer (96) there was a significant increase in the proportion of those who were blood group O (P< 0·025); however, there were no significant differences in the proportions of non-secretors.H. pyloriwas identified in 62 % of the 454 patients: 59·5 % of those without evidence of ulcers; 62·5 % of those with gastric ulcer; 88% of those with duodenal ulcer (P< 0·0005). These bacteria were cultured more often and in higher numbers from patients with duodenal ulcer (P< 0·025). There was no association between ABO blood group and prevalence ofH. pylori. The prevalence ofH. pyloriamong non-secretors with gastric ulcer (12·5%) was significantly lower than that for non-secretors with duodenal ulcer (100%) (P< 0·0005). This was not observed for secretors.
