Objective To investigate the relationship between Helicobacter pylori ( H. pylori) infection and gallstones or gallbladder polyps. Methods This retrospective analysis included 27,881 individuals who underwent health examinations that included a H. pylori test and an abdominal ultrasound scan. Patients were divided into four groups: gallbladder polyp (P group), gallstone (S group), gallstone and gallbladder polyp (SP group), and no gallbladder disease (N group). Case–control matching was used to select the participants in the control group. Results The mean ages of participants in the P, S, and SP groups were all significantly higher than the mean age of participants in the N group. The proportions of participants with each type of body mass index significantly differed between the N and P groups, and between the N and S groups. In total 45.7% of participants exhibited H. pylori infection. After case-control matching, the proportion of participants with H. pylori infection did not significantly differ according to the presence or absence of gallbladder polyps. Similar results were observed regarding gallstones, as well as gallstones and gallbladder polyps. Conclusion H. pylori infection might not be related to gallbladder polyps or gallstones.

Background: Helicobacter pylori (H. Pylori) is a common infection in children, especially in the developing countries. The infection is usually asymptomatic but it may cause gastrointestinal diseases. In children, the symptoms include abdominal pain, vomiting and anemia. Recurrent abdominal pain (RAP) is a common cause of children’s referral. But, whether H. Pylori causes RAP in children has to be scrutinized to prevent further complications by proper diagnosis and treatment. However, there is still controversy in the literature regarding this issue. Therefore, we aimed to assess the association between H. Pylori and RAP in children. Materials and Methods: In this case-control study, the children with RAP aged 2-10 years who referred to a private pediatric clinic in Marvdasht, Iran, were compared to other children without RAP, during 2015. The sample size was calculated to be 70 for each case and the control group. The patients were visited by a gastro-enterologist who recorded the demographic data of all the patients and the findings of stool test for H. Pylori. To assess the association of RAP with H. Pylori, the odds ratio was calculated. The statistical analysis was performed using SPSS 20.0 software. The P-values less than 0.05 were considered as statistically significant. Results: The mean age of the participants was 7.35±3.11 (with a range of 2-10). In the case group, 41/70 and 69/70 of the control group were girls. H. Pylori was found positive in 37 cases (52.9%) of the case group and 11 (15.7%) in the control group (P<0.001, OR=6.01, 95% CI=2.71-13.34). Logistic regression with adjustment for age indicated that there was a positive association between positive H. Pylori and abdominal pain (OR=16.69, 95% CI=4.71-59.18). This model also showed that by adjusting the H. Pylori test result, age was also positively associated with abdominal pain (OR=0.27, 95% CI=0.18-0.45). A T-test also indicated that the mean titer of H. Pylori was significantly higher in case group (1.42±1.29) than the control group (0.86±1.52) (P=0.020). Conclusion: There was a statistically significant correlation between H. Pylori and RAP. [GMJ. 2016;5(1):19-24]

4091 Background: The relationship between Helicobacter pylori (H.pylori) and hepatocellular carcinoma (HCC) was first proposed in 1994. Since then, several studies have been performed to explore the association. The role of Hepatitis C (HCV) viruses coexisting with H.pylori in causing HCC was also studied. With the emergence of data in this regard, a causal relationship has been postulated, but not confirmed, and hence the relationship remains controversial. Our meta-analysis aims to summarize the research on this topic and investigate if there exists a relationship between H. pylori infection and the development of HCC and if the presence of HCV along with H.pylori plays a role in liver carcinogenesis. Methods: Following PRISMA guidelines, we performed a systematic review of all relevant studies published in the literature using keywords “Helicobacter pylori” and “Hepatocellular carcinoma” on major literature databases, including PubMed, EMBASE, Web of Science, and Cochrane controlled trials register. A total of 656 studies were identified between 1994 to March 2020, out of which 26 studies qualified under our selection criteria. Patients positive for HCC are included as cases and patients that did not have HCC under control group. In both groups, H.pylori positive patients and their HCV status, was identified. Results: Out of the 26 studies included in the final analysis, the prevalence of H. pylori infection was 64.78% (561 of 866) amongst HCC cases and 47.92% (1718 of 3585) in the non-HCC control group. The summary odds ratio for the association of H. pylori infection with the risk for HCC using the random-effects model was determined to be 4.75 (95% CI, 3.06-7.37), I²=63%. Subgroup analysis to determine the odds of developing HCC in the presence of H.pylori and HCV coinfection, was 13.97 (95% CI, 3.94-49.61), I²=81%. Whereas, the odds of developing HCC in the presence of only HCV without H.pylori was found to be 2.21 (0.70-6.94), I²=79. Subgroup analysis by study design showed no significant difference between the study groups (P= 0.5705). Conclusions: Our meta-analysis showed a positive association between H. pylori infection and the development of HCC. It showed a significantly higher risk of developing HCC in the presence of HCV infection along with H.pylori. Further prospective cohort studies are needed to prove the causal relationship, especially in cases of Hepatitis B, C coinfection, and cirrhotic patients.[Table: see text]

The association of Helicobacter pylori (H. pylori) infection with functional dyspepsia has been well studied. However, the data on the relationship between H. pylori infection and irritable bowel syndrome (IBS) are conflicting. This study aims to elucidate the association between H. pylori infection and IBS. PubMed, Cochrane Library, CINAHL and SCOPUS databases were searched to identify eligible English articles published up to December 2019. Cross-sectional studies, case–control studies and cohort studies reporting both prevalence of H. pylori infection and IBS were selected for the detailed review. The pooled odds ratio (ORs) and their 95% confidence interval (CI) were calculated. A total of 7269 individuals in four cross-sectional studies and six case-control studies were included. The prevalence of H. pylori infection ranged from 12.8% to 73.4% in the control group, and 9.7% to 72.1% in the IBS group. The combined OR for H. pylori infection was 1.10 (95% CI: 0.93–1.29, I2: 37.5%). In a subgroup analysis of IBS defined according to Rome criteria, the OR for H. pylori infection was 1.10 (95% CI: 0.93–1.30, I2 = 31.7%). In this meta-analysis, H. pylori infection was not significantly associated with IBS. Well-designed studies are needed to identify the relationship between H. pylori infection and IBS.

Background: Helicobacter pylori is an important pathogen in the upper digestive tract. It is of great significance to properly understand the risk factors for the transformation of Barrett esophagus into esophageal carcinoma. However, the relationship between H. pylori and gastroesophageal reflux disease (GERD) and Barrett esophagus remains controversial, and the correlation with immune function has been rarely reported. Objectives: This study investigated the effect of H. pylori infection on Barrett esophagus and its correlation with immune function. Methods: We recruited 40 patients with Barrett esophagus (Barrett esophagus group) and 40 patients with GERD (GERD group). In addition, 40 healthy controls were selected for the control group. Esophageal function and its correlation with immune function were measured in each group. Results: The positivity rate of H. pylori (P < 0.05) and sphincter pressure were lower in both Barrett esophagus and GERD groups than in the control group, while the levels of PGI, PGII, PGI/II, and G-17 were higher (P < 0.05). The levels of CD3+, CD4+, and CD4+/CD8+ were lower in the Barrett esophagus group than in the GERD group, but they were negatively correlated (P < 0.05) with H. pylori infection. The level of CD8+ was higher in the Barrett esophagus group, and it was positively correlated (P < 0.05) with H. pylori infection. Conclusions: Helicobacter pylori infection may protect against Barrett esophagus by reducing gastric acid secretion and increasing lower esophageal sphincter pressure. Besides, it has a certain correlation with immune function.

Abstract Aim Helicobacter pylori (H. pylori) is one of the most common, well-known pathogenic agents in the development of peptic ulcers. Some investigators have shown a relationship between H. pylori and recurrent aphthous stomatitis (RAS). However, this relationship is controversial. The aim of this study was to determine the association between H. pylori and RAS using the urea breath test (UBT). Methods and Materials Forty-three patients with RAS and 44 non-RAS controls were evaluated. There were no differences in gender or age in the two groups. The UBT was used to detect H. pylori infection. Data were analyzed using the Chi Square Test. Results Sixteen individuals in the RAS patients (37.2%) and 14 individuals in the control group (31.8%) had a positive breath test. The difference was not considered statistically significant (p=0.597). Conclusion In the present study no statistically significant difference was found between frequency of a positive UBT in the RAS patients and the control group. Clinical Significance Since the probability of a positive test was higher in the more severe cases this factor needs to be considered in the diagnosis and treatment of RAS.

Objective Helicobacter pylori commonly occurs in the stomach, but localizations outside the stomach and related diseases have also been investigated. However, the relationship between H. pylori and gallstones remains controversial. We aimed to investigate the relationships between H. pylori in the stomach and the gallbladder and gallstones. Methods This prospective case-control study included patients who underwent cholecystectomy because of gallstones, pancreatic head cancer, or hepatic resection. The patients were separated into two groups according to the detection of H. pylori in gallbladder samples using Giemsa staining. Stomach H. pylori status was based on previous gastroscopy. Results The study enrolled 60 patients, comprising 27 patients with gallstones and 33 without. There was no significant difference in the incidence of gallstones between patients with or without H. pylori in the stomach or gallbladder. Furthermore, the presence of H. pylori in the stomach was measured in 14 patients and was significantly correlated with H. pylori in the gallbladder. Conclusion The current study showed no relationship between the occurrence of gallstones and the presence of H. pylori in either the gallbladder or the stomach. In contrast to previous reports, this suggests that H. pylori does not play a role in the development of gallstones.

Background and Objectives: Although there are many studies that investigate the relationship between duodenogastric reflux (DGR) and Helicobacter pylori in adult patients, the reported data are contradictory. In addition, there are very few studies in the literature investigating the relationship between DGR and H. pylori in the pediatric age group. In the present study, we investigated the effect of primary DGR on H. pylori and gastritis. Materials and Methods: A total of 361 patients who were referred to the clinic of our hospital with dyspeptic complaints who had an upper gastrointestinal system endoscopy and a gastric biopsy were included in the study. Results: DGR was detected in 45 cases, and 316 cases that did not have DGR were considered as the control group. Comparisons were made between the DGR cases and the control group in terms of risk factors (age, gender), the presence and density of H. pylori, and the presence and severity of gastritis. The average age of the patients who were included in the study was 11.6 ± 4.6 years. A total of 128 (36%) of the cases were male and 233 (64%) were female. DGR was present in 45 (13%) of the cases. The average age of the patients with DGR was 13.9 ± 3.1 years, the average age of the control group was 11.3 ± 4.7, and there were statistically significant differences (p < 0.001). No significant differences were detected in terms of gender between DGR and the control group (p > 0.05). H. pylori (+) was detected in 29 (64%) of patients with DGR, and in 202 (64%) of the control group. No significant differences were detected between H. pylori prevalence (p = 0.947). Gastritis was detected in 37 (82%) of the patients with DGR, and in 245 (77%) of the control group (p = 0.476). No significant differences were detected between the presence and density of H. pylori, gastritis presence, severity and DGR (p > 0.05). Conclusions: The ages of patients with DGR were significantly higher than in the control group, and advanced age was shown to be a risk factor for primary DGR. It was found that the presence of DGR has no effect on the presence and severity of H. pylori. Given this situation, we consider it is important to eradicate H. pylori infection, especially in the case where H. pylori is present together with DGR.

Introduction: In most individuals H. Pylori is acquired early in the life (before 5 years). H. Pylori infection is more common in the third world countries, where about 90% of adults may be infected. Helicobacter pylori is one of the suspected causes of halitosis in children. Objectives: To evaluate the relationship of helicobacter pylori and halitosis. Patients and Material: 33 patients with chief complaint of halitosis included in our study. Halitosis was evaluated as a subjective symptom in this study. Careful history was obtained. All patients underwent physical examination in order to rule out sinusitis, otitis, and possible cause of halitosis. 67 patients without halitosis were selected as control group. All patients were aged 4-17 years old. Urea Breath Test was done for all patients. UBT has >95% sensitivity and specifity for diagnosis of H.pylori infection. Chi-square test and Yate’s corrected x2 was used to analyzes finding. Epi-info ver 6 were used. Results: In the case groups 7 patients had H. pylori infection and 26 patients had not. In the control group 18 patients had H.pylori infection and 49 patients had not halitosis (P=0.53). Conclusions: There is no significant differences between case and control group. In this study we did not find relationship between H.pylori infection and halitosis.

The prevalence of Helicobacter pylori infection is high worldwide, while numerous research has focused on unraveling the relationship between H. pylori infection and extragastric diseases. Although H. pylori infection has been associated with thyroid diseases, including thyroid nodule (TN), the relationship has mainly focused on potential physiological mechanisms and has not been validated by large population epidemiological investigations. Therefore, we thus designed a case-control study comprising participants who received regular health examination between 2017 and 2019. The cases and controls were diagnosed via ultrasound, while TN types were classified according to the guidelines of the American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS). Moreover, H. pylori infection was determined by C14 urea breath test, while its relationship with TN type risk and severity was analyzed using binary and ordinal logistic regression analyses. A total of 43,411 participants, including 13,036 TN patients and 30,375 controls, were finally recruited in the study. The crude odds ratio (OR) was 1.07 in Model 1 (95% CI = 1.03–1.14) without adjustment compared to the H. pylori non-infection group. However, it was negative in Model 2 (OR = 1.02, 95% CI = 0.97–1.06) after being adjusted for gender, age, body mass index (BMI), and blood pressure and in Model 3 (OR = 1.01, 95% CI = 0.97–1.06) after being adjusted for total cholesterol, triglyceride, low-density lipoprotein, and high-density lipoprotein on the basis of Model 2. Control variables, including gender, age, BMI, and diastolic pressure, were significantly correlated with the risk of TN types. Additionally, ordinal logistic regression results revealed that H. pylori infection was positively correlated with malignant differentiation of TN (Model 1: OR = 1.06, 95% CI = 1.02–1.11), while Model 2 and Model 3 showed negative results (Model 2: OR = 1.01, 95% CI = 0.96–1.06; Model 3: OR = 1.01, 95% CI = 0.96–1.05). In conclusion, H. pylori infection was not significantly associated with both TN type risk and severity of its malignant differentiation. These findings provide relevant insights for correcting possible misconceptions regarding TN type pathogenesis and will help guide optimization of therapeutic strategies for thyroid diseases.

Background. Several studies have shown a possible involvement ofHelicobacter pylori(H. pylori) infection in individuals with hyperemesis gravidarum (HG), but the relationship remains controversial. This meta-analysis was performed to validate and strengthen the association between HG andH. pyloriinfection.Methods. PubMed, Embase, and Web of Science databases up to March 20, 2014, were searched to select studies on the prevalence ofH. pyloriinfection between pregnant women with HG and the normal pregnant control subjects.Results. Of the HG cases, 1289 (69.6%) wereH. pylori-positive; however, 1045 (46.2%) wereH. pylori-positive in control group. Compared to the non-HG normal pregnant controls, infection rate ofH. pyloriwas significantly higher in pregnant women with HG (OR = 3.34, 95% CI: 2.32–4.81,P<0.001). Subgroup analysis indicated thatH. pyloriinfection was a risk factor of HG in Asia, Africa, and Oceania, especially in Africa (OR = 12.38, 95% CI: 7.12–21.54,P<0.001).Conclusions.H. pylorishould be considered one of the risk factors of HG, especially in the developing countries.H. pylorieradication could be considered to relieve the symptoms of HG in some intractable cases.
