The Relationship

Background: In developing countries, Helicobacter pylori infection is common, as are intestinal parasites. Socioeconomic circumstances and low personal hygiene lead to the spread of these infections. This research aimed to evaluate the relationship between intestinal parasites and H. pylori in Khartoum, Sudan. Methods: This study was conducted in various hospitals in Khartoum between June and October 2018. The study involved 200 individuals: 100 patients with H. pylori as a case group and 100 healthy individuals as a control group. A stool sample was taken from each individual, and wet preparation, saturated sodium chloride flotation and formal ether concentration were used to detect intestinal parasites. Results: The results showed that 23% of H. pylori patients and 10% of healthy individuals had gastrointestinal parasites; Entamoeba histolytica was found in 12% of H. pylori cases followed by Entamoeba coli (7%) and Giardia lamblia (4%). Control group: Entamoeba histolytica in 5% followed by G. lamblia in 3% and E. coli in 2% of individuals. There was a significant difference in the prevalence of intestinal parasites between groups (P = 0.013). The prevalence rate of intestinal parasites among men and women was 24% and 22%, respectively, in the case group, and 9% and 11%, respectively, in the control group. In the case group, the highest prevalence rates (40% and 38%) were found among the age groups 1-15 and 46-60 years old, respectively, while the lowest rate (10.7%) was found among the 31-45 age group. In the control group, the highest prevalence rate (15%) was among the 31-45 age group, the lowest prevalence rate (8%) was found among the 16-30 age group. Conclusion: Together, we found that intestinal parasites are more common in patients with H. pylori. We also noticed that the rate of infection was not affected by gender while the age group was affected.

In recent years, the prevalence of asthma and allergic rhinitis has increased in developed countries. Helicobacter pylori (H. pylori) infection can exacerbate asthma. The purpose of this study was to investigate the relationship between asthma and H. pylori seroprevalence in children. In this cross-sectional study, 100 children aged 5-15 years hospitalized in Besat hospital in Sanandaj were investigated from 2015 to 2016. Fifty children with asthma were considered as the case group and 50 non-asthmatic children as the control group. The questionnaires were completed, including demographic information, history of asthma, exposure to cigarette smoke, and family history of gastric and duodenal ulcers. Blood samples were collected from the children, and the serum level of specific antibodies (IgG) of H. pylori was measured. There were 42 and 31 boys in the case and control group, respectively. The mean age in the case group was 8.12±2.29 and in the control group was 8.9±2.52 years. In the case group, 48% were exposed to cigarette smoke and in the control group, 18%. There was a statistically significant difference between the groups in terms of gender and exposure to cigarette smoke (P=0.001 and P=0.013, respectively). There was no significant difference between the case and control groups in terms of H. pylori seroprevalence. (P=0.211). There was no significant association between asthma and H. pylori seroprevalence. (P=0.22). According to our study, there no correlation between childhood asthma and H. pylori seroprevalence. © 2019 Tehran University of Medical Sciences. All rights reserved.

Background: Primary Open-Angle Glaucoma (POAG) the most common form of glaucoma is a neurodegenerative disease, which is the third most common cause of blindness worldwide. It is estimated that 60 million people in the world are affected by this disease and 8.4 million are bilaterally blind. Among the various factors that have been implicated in the pathophysiology of this disease is infection with Helicobacter pylori (HP), a Gram-negative bacterium that is commonly found in stomach and present in approximately one-half of the world’s population. Establishment of such a causal correlation will probably have important practical applications as the eradication of H. pylori might lead to developments in the treatment of glaucoma. Objectives: To investigate the association between Primary Open-Angle Glaucoma (POAG) and Helicobacter Pylori infection and to observe fluctuations in intra ocular pressure after Helicobacter Pylori infection eradication. Design: Duration based, prospective observational study. Participants: 50 patients with documented Primary Open-Angle Glaucoma (POAG) as case group and 50 non-glaucoma participants as control group. Methods: Upper gastrointestinal endoscopy was performed to evaluate macroscopic abnormalities, and gastric mucosal biopsy specimens were obtained for the presence of H. pylori infection tested by Rapid Urease Test (RUT). All subjects underwent detailed ocular examinations including visual acuity, slit-lamp examination, fundoscopy, intra-ocular pressure recording, gonioscopy, GHT to assess visual fields and OCT of optic nerve head. Results: In 90% of POAG patients of case group and in 68% of non-glaucoma participants of control group Helicobacter pylori infection was detected by RUT (P-Value=0.007). Conclusion: H. pylori infection is more frequent in glaucoma patients, perhaps more so in those of Indian ethnicity. It may play a role as a secondary aggravating factor or even may be the primary cause. The establishment of such a causal relationship will probably have important practical applications as the eradication of H. pylori might lead to developments in the treatment of glaucoma.

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]

Helicobacter pylori are Gram-negative curved rods that habitats the gastric mucosa and considered as the leading causes of stomach ulcers and duodenal ulcers in humans. The main object of this study was to evaluate the influences of the bacteria on several hematological parameters. A total of 60 patients aged between 15 to 40 years were included in this study (30 male and 30 female) in addition to 30 healthy individuals from the same ages who were considered as a control group. Venous blood (4 ml) was obtained from the study population and investigated for complete blood count (CBC) using an automated hematology analyzer. The results revealed that there is a substantial decrease (p 0.01) in Hemoglobin (Hb), Red cell distribution width (RDW), and mean corpuscular hemoglobin (MCH) in patients compared to control. However, no significant difference in Red blood cells (RBCs), Hematocrit (HCT), mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC) in patients compared to control. Also, no significant differences were found in the white blood cell (WBC) between H. pylori infected and non-infected persons. Otherwise, there are significant differences (p 0.01) in lymphocytes, monocytes, granulocytes in the patients and healthy individuals. The results also found that there are significant statistical differences in some of the hematologic parameters among study groups according to their gender. The study concluded that Hb, RDW, lymphocytes, monocytes, granulocytes are decreased in H. Pylori infected patients suggesting that infection may have direct effects on blood parameters.

The Relationship

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 Relationship

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.

Background: T helper 17 (Th-17) cell, a proinflammatory subset of CD4 T cells, have an essential role in immunity against Helicobacter pylori (H. pylori) infection. Objectives: This study aimed to evaluate expression of selected Th-17 cells associated cytokines (IL17, IL-21, IL-22, IL-23, IL-26 and TNF-α) in H. pylori-infected patients and to recognize their responsibility in H. pylori associated chronic gastritis with different severity. Methodology: This study is a case control study. The case group included 25 H. pyloripositive patients suffering from chronic gastritis. The control group included 25 age and sex-matched healthy individuals without any dyspeptic symptoms and negative for H. pylori. Infection with H. pylori in all participants was determined by detection of H. pylori stool antigen by enzyme-linked immunosorbent assay (ELISA) kit. Certain cytokines expression (IL-17, IL-21, IL-22, IL-23, IL-26 and TNF-α) in serum samples from all participants were tested using ELISA. Results: Comparing the serum cytokines expression in cases and controls, IL-17, IL-21 IL-23 and TNF-α were significantly higher in cases while IL-22 and IL-26 were higher in cases but not statistically significant. Both serum IL-17 and TNF-α expressions were statistically significant higher in cases with moderate or severe forms of chronic gastritis than in cases with mild form of chronic gastritis. However, the levels of IL-21, IL-22, IL-23 and IL-26 showed insignificant variation regarding chronic gastritis severity. Conclusion: Th-17 cells are responsible for the pathogenesis of H. pylori infection and the severity of gastritis. So, down regulation of Th-17 cells associated cytokines offers a promising therapy to diminish H. pylori associated gastritis.

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.
