Heliyon 2022; 8:e12612. [PMID: 36593846 PMCID: PMC9803786 DOI: 10.1016/j.heliyon.2022.e12612] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 10/24/2022] [Accepted: 12/16/2022] [Indexed: 12/24/2022] Open
Abstract
Background Helicobacter pylori (H. pylori) infection and chronic dyspepsia represent significant medical burdens in the developing world. An accurate assessment of the prevalence of chronic dyspepsia, as well as of the effectiveness of population-based screening and eradication of H. pylori are warranted. Objectives We determined the prevalence of H. pylori and chronic dyspepsia within the general adult population in a region of eastern Uganda. Independent predictors of H. pylori infection were assessed. Finally, we evaluated the efficacy of standard triple therapy on H. pylori eradication. Methods Of 400 randomly selected adult residents in eastern Uganda, 376 were administered a validated, chronic dyspepsia questionnaire and provided a stool sample for H. pylori testing. H. pylori-positive participants were given standard triple therapy and monitored for medication adherence. The efficacy of triple therapy on H. pylori eradication was determined by fecal antigen testing after treatment. Log-linear and logistic regression analyses identified predictors of H. pylori positivity and eradication failure. Results H. pylori prevalence within the study population was 48%. The prevalence of chronic dyspepsia was 87%. The presence or severity of dyspepsia did not predict H. pylori infection. However, a higher level of education was an independent predictor of H. pylori infection. Standard triple therapy resulted in ∼90% eradication. Missing at least four doses of any of the triple therapy medications over the 14-day course predicted eradication failure. Conclusions In our study population, chronic dyspepsia did not predict H. pylori infection, though clinical suspicion for this prevalent pathogen should nonetheless remain high. Population-based screening and adherence to triple therapy are effective at eradicating H. pylori within this region.

Ngaiza AI, Yahaya JJ, Mwakimonga AK, Vuhahula E, Mnango L, Mwakigonja AR, Kawishe GJ, Ng D. Histologic detection of Helicobacter pylori by the immunohistochemical method using anti-Helicobacter pylori polyclonal antibody: A cross-sectional study of patients with gastric pathologies at the Muhimbili National Hospital in Dar-es-salaam, Tanzania. Arab J Gastroenterol 2022; 23:7-14. [PMID: 34840096 DOI: 10.1016/j.ajg.2021.11.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Revised: 05/09/2021] [Accepted: 11/01/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND AND STUDY AIM Immunohistochemistry is one of the superior methods and is regarded as the gold standard for the detection of Helicobacter pylori. We aimed to detect the presence of Helicobacter pylori in gastric biopsies among patients at the Muhimbili National Hospital from January 2012 to December 2016. Also, we determined the predictors of Helicobacter pylori infection. PATIENTS AND METHODS Retrospectively, we retrieved the tissue blocks of gastric biopsies at the Central Pathology Laboratory of the patients with different gastric pathologies at the Muhimbili National Hospital from January 2012 to December 2016. Helicobacter pylori were detected using anti-Helicobacter pylori polyclonal antibodies. Binary logistic regression analysis was done to determine the predictors of Helicobacter pylori infection. A two-tailed p < 0.05 was considered significant. RESULTS The prevalence of detection of Helicobacter pylori was 37.1% (63/170) using immunohistochemistry compared to 32.4% (55/170) using histology. Peptic ulcer disease, the absence of gastric cancer, and chronic gastritis were the predictors of Helicobacter pylori infection in our study (AOR = 0.2, 95% CI = 0.06-0.70, p = 0.011, AOR = 3.23, 95% CI = 1.02-10.29, p = 0.047, AOR = 0.32, 95% CI = 0.12-0.87, p = 0.025, respectively). CONCLUSION In this study, Helicobacter pylori infection was associated with the presence of peptic ulcer disease, chronic gastritis, and the absence of gastric cancer. The rate of detection of Helicobacter pylori infection was higher in tissue blocks of elderly patients than in those of young patients. Also, gastric cancer was more prevalent in old female patients.

Potential Predictors and Prevalence of Helicobacter pylori Infection Among Adult Patients With Dyspepsia: A Retrospective Study From Qatar. Cureus 2021; 13:e16216. [PMID: 34367816 PMCID: PMC8341225 DOI: 10.7759/cureus.16216] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/06/2021] [Indexed: 12/04/2022] Open
Abstract
Aim To study the prevalence of Helicobacter pylori (H. pylori) infection among dyspeptic patients of various ethnic origins in Qatar and determine the association between H. pylori infection and various demographic factors and endoscopic findings. Methods A retrospective data review was carried at Alkhor Hospital, Hamad Medical Corporation, Qatar. Adult patients who underwent endoscopy for the evaluation of dyspepsia between January 2011 to December 2017 were included. Patients who underwent endoscopy for reasons other than dyspepsia and those with incomplete data were excluded. Results Of the 638 subjects included, 58.9% were males, and the mean age of the subjects was 42.2 years (range 18-79 years). Epigastric pain (80.6%) was the most common symptom, followed by heartburn (26.2%). Forty point nine percent (40.9%) had a positive Campylobacter-like organism (CLO) test for H. pylori. A higher prevalence of H. pylori infection was observed among subjects between 31-50 years of age (43.6%) and 18-30 years (40.5%), and in Asian (42.2%) and Middle East and North African nationals (MENA) nationals (40%). Among the endoscopic findings, esophagitis (P=0.002) and gastritis (P=0.001) showed a statistically significant correlation with H. pylori positivity. Univariate regression analysis revealed an increased risk for H. pylori infection among all age groups except above 65 years, with an odds ratio (OR) of more than 2 in all the three age groups. Among various ethnicities, patients from Asia and MENA countries showed an increased risk of getting H. pylori infection (OR 1.16, 95% CI; 0.77,1.75 and OR 1.06, 95% CI 0.70,-1.61 respectively). The multivariable logistic regression analysis showed that subjects with endoscopic findings of esophagitis (adjusted OR 1.67, 95%CI 1.19, 2.34; P=0.003), gastritis (adjusted OR 1.79, 95%CI 1.27, 2.57; P=0.001), and duodenal ulcer (adjusted OR 2.41, 95%CI 1.24, 4.70; P=0.010) remained significantly associated with an increased risk of having H. pylori infection. Conclusion The burden of H. pylori infection in patients with dyspepsia undergoing endoscopy is not low in Qatar. Less than 65 years of age, Asian nationals, and being from the MENA region were the demographic predictors for H. pylori infection. The finding of esophagitis, gastritis, and duodenal ulcer on endoscopy were independent endoscopic predictors for having H. pylori infection.

Abstract
Background Globally, H. pylori infection affects approximately 4.4 billion people. The burden of the infection varies within and between countries, with a higher prevalence reported from developing countries including Ethiopia. Thus, this study aimed to determine the magnitude and predictors of H. pylori infection among dyspeptic patients who visited Wachemo University Nigist Eleni Mohammed Memorial Referral Hospital, Southwest Ethiopia. Methods Consecutive willing dyspeptic adult patients (n=405) were enrolled in a cross-sectional study done from September to December 18, 2019. Socio-demographic and behavioral characteristics of the study participants were gathered by a pretested structured questionnaire. Stool samples were examined for H. pylori antigens using Wondfo one step H. pylori feces test kit. SPSS version 20 was utilized to compute descriptive statistics, binary and multivariate logistic regression. A p-value of <0.05 was considered statistically significant. Results Mean age of patients was 30 (± 7.4 SD) years, and 56.8% of participants were females. About 51.4% (208/405) of adult dyspeptic patients were infected with H. pylori. Being female gender (AOR꞊ 2.56, CI 95% ꞊1.61-4.07, p꞊0.001), consumption of alcohol (AOR꞊1.95, CI 95% ꞊1.02-3.73, p꞊ 0.019) and being undernourished (underweighted) (AOR꞊ 4.59, CI 95%꞊ 1.28-16.45, p꞊0.019) were independent predictors of H. pylori infection. Conclusion In the study area, high (51.4%) magnitude of H. pylori infection was observed in dyspeptic patients and significantly associated with female gender, alcohol consumption, and undernourishment.

Abstract
Aim To investigate the current prevalence and management of dyspepsia in rural Eastern Uganda. Methods Residents older than 18 years of age across 95 study sites in Namutumba District, Eastern Uganda were surveyed. Each respondent was administered a questionnaire about dyspepsia and pertinent health-seeking behaviors. Health workers at 12 different clinics were also assessed on their competence in managing dyspepsia. Proportion-based analysis was used to determine self-reported outcome variables reported in this study, including: prevalence of dyspepsia; breakdown of symptoms; initial diagnosis location; management strategies; and appropriate medication usage. Results 397 residents (average age of 41.2 years) participated in this study (54.4% males, 45.6% females). 57.9% self-reported currently having dyspepsia, of average duration 4.5 years. Of this subset, 87% reported experiencing epigastric pain, and 42.2% believed that ulcers were “wounds in the stomach.” Only 3% of respondents had heard of Helicobacter pylori (Hp). Respondents varied in their management of dyspepsia, with frequent eating (39.1%), doing nothing (23.9%), and taking Western medicine (20%) being the most common strategies. The diagnosis of “peptic ulcer disease” was made by a health worker in 64.3% of cases, and 27% of cases were self-diagnosed. Notably, 70.3% of diagnoses at formal health centers were based on clinical symptoms alone and only 22.7% of respondents received treatment according to Ugandan Ministry of Health guidelines. Among the 12 health care workers surveyed, 10 cited epigastric pain as a common symptom of “ulcer,” although only two reported having heard of Hp. Only two out of 12 clinics had the capability to prescribe the triple therapy as treatment for presumed Hp. Conclusion There is a high incidence of dyspepsia in Eastern Uganda, and current management strategies are poor and inconsistent, and may contribute to antibiotic resistance. Further studies are needed to investigate the causes of dyspepsia to guide appropriate management.

Abstract
BACKGROUND More than 50% of the people are infected worldwide with H. pylori which causes significant public health morbidity and mortality. The distribution is quite different from country to country. Hence, early information is very important to prevent upper gastrointestinal complications. The current study aimed to assess the magnitude of H. pylori and associated risk factors among symptomatic patients attending at Jasmin internal medicine and pediatrics specialized private clinic from August 2017 until May 2018 in Addis Ababa city, Ethiopia. METHODS A cross-sectional study was conducted among 487 patients with upper gastrointestinal tract complaints attending at Jasmin internal medicine and pediatrics specialized private clinic from August 2017 until May 2018. Convenient sampling technique was used to enroll participants. Information regarding to risk factors was assessed using structured questionnaire. Stool samples were collected for H. pylori antigen test. Data was entered and analyzed using SPSS version20 statistical software and a p-value less than 0.05 was considered as statistically significant. RESULTS The overall prevalence of H. pylori among participants using stool antigen was 36.8% (n = 179/487). Regarding to family income status, those who have low monthly income were more likely to be infected with H. pylori infection (AOR = 6.056, CI 95% = 1.603-22.881, P = 0.037). In addition, families with low educational level were more likely to be infected with H. pylori infection than higher level education (AOR = 4.150, CI95% = 1.059-16.270, P = 0.041). Number of family members in the house-hold, type of toilet they used and source of drinking water were not significantly associated with H. pylori infection. CONCLUSIONS The prevalence of H. pylori infection was 36.8% and it was related to low income and low education levels. This finding calls for improving the socioeconomic status of the community. Moreover, further studies are needed to investigate potential risk factors for H. pylori infection.

Helicobacter pylori Infection and Its Risk Factors: A Prospective Cross-Sectional Study in Resource-Limited Settings of Northwest Ethiopia. THE CANADIAN JOURNAL OF INFECTIOUS DISEASES & MEDICAL MICROBIOLOGY = JOURNAL CANADIEN DES MALADIES INFECTIEUSES ET DE LA MICROBIOLOGIE MEDICALE 2018; 2018:9463710. [PMID: 30420905 PMCID: PMC6211158 DOI: 10.1155/2018/9463710] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/19/2018] [Accepted: 09/19/2018] [Indexed: 12/13/2022]
Abstract
Background Helicobacter pylori (H. pylori) is implicated for the causation of gastrointestinal tract infections including gastric cancer. Although the infection is prevalent globally, the impact is immense in countries with poor environmental and socioeconomic status including Ethiopia. Epidemiological study on the magnitude of H. pylori and possible risk factors has priceless implication. Therefore, in this study, we determined the prevalence and risk factors of H. pylori infection in the resource-limited area of northwest Ethiopia. Methods A prospective cross-sectional study was conducted on northwest Ethiopia among 201 systematically selected dyspeptic patients. Data were collected using a structured and pretested questionnaire, and stool and serum samples were collected and analyzed by SD BIOLINE H. pylori Ag and dBest H. pylori Disk tests, respectively. Chi-square test was performed to see association between variables, and binary and multinomial regression tests were performed to identify potential risk factors. P values <0.05 were taken statistically significant. Result Prevalence of H. pylori was found to be 71.1% (143/201) and 37.3% (75/201) using the dBest H. pylori Test Disk and SD BIOLINE H. pylori Ag test, respectively. H. pylori seropositivity, using dBest H. pylori Disk tests, is significantly associated in age groups <10 years (P=0.044) and married patients (P=0.016). In those patients with H. pylori (a positive result with either the Ab or Ag test), drinking water from well sources had 2.23 times risk of getting H. pylori infection (P=0.017), and drinking coffee (1.51 (0.79–2.96, P=0.025)) and chat chewing (1.78 (1.02–3.46, P=0.008) are the common risk factors. Conclusion The present study discovered considerable magnitude of H. pylori among the dyspeptic patients in the study area. H. pylori infection is frequent in individuals drinking water from well sources, and thus, poor sanitation and unhygienic water supply are contributing factors. Policies aiming at improving the socioeconomic status will reduce potential sources of infection, transmission, and ultimately the prevalence and incidence of H. pylori.

Abstract
Background Dyspepsia is a common problem in the community and clinical practice with symptom(s) considered arising from the gastroduodenal region. Dyspepsia burden and associated factors vary from country to country. The aim of this study was to determine the prevalence of uninvestigated dyspepsia (UD) using Rome III criteria, associated risk factors and self-reported dyspepsia symptoms’ correlation with H. pylori infection. Methods A cross-sectional study was conducted among randomly selected 318 out patients with gastrointestinal complaints during the period from September 1 to December 30, 2015. All patients completed a questionnaire for collecting data regarding sociodemographic, lifestyle and functional gastrointestinal disorders. Diagnosis of dyspepsia was made according to the Rome III criteria. H. pylori infection was assessed using stool antigen test. SPSS version 20.0 statistical software package was used for data analysis. Results From a total of 318 patients, 48.4% had UD according to Rome III criteria; with 42.1% symptoms of epigastric pain/burning, 26.1% postprandial fullness and 22.6% early satiation. Epigastric pain/burning (AOR = 1.92, 95% CI 1.07–3.43), early satiation (AOR = 2.68, 95% CI 1.38–5.20) and belching (AOR = 4.7, 95% CI 1.54–14.40) were significantly correlated with H. pylori infection. H. pylori infection (AOR = 4.33, 95% CI 2.41–7.76) and aspirin/NSAIDs consumption (AOR = 5.29, 95% CI 2.82–9.93) were independent risk factors for UD. However, consumption of raw fruits/ vegetables at least once a week (AOR = 0.48, 95% CI 0.24–0.98) and taking two or more cups of tea a day (AOR = 0.339, 95% CI 0.17–0.70) were inversely associated with UD. Conclusions UD is highly prevalent among adults with gastrointestinal complaints. H. pylori infection is significantly associated with UD and correlates with its symptoms. Individuals with epigastric pain/burning, early satiation and belching should be primary focus of H. pylori infection diagnosis and treatment. The role of consumption of tea, raw fruits and vegetables on dyspepsia needs further large scale study.

Abstract
Background The growing attention given to H. pylori is not surprising since this pathogen colonizes more than at least half of the world’s inhabitants. In Ethiopia particularly in Gondar, there is no current study conducted about seroprevalence and trend of the prevalence of H. pylori. Therefore the aim of this study was to determine the seroprevalence and its trend of the H. pylori in three consecutive years in North Gondar, North West Ethiopia. Findings Retrospective study was conducted using data collected from log book of serology laboratory of Gondar University Hospital. We collected data from January 2009 to December 2011 and 1388 subjects were included whose data were registered completely. Among all of the study subjects, 912 (65.7%) were found to be seropositive. The prevalence in male was 449/679 (66.1%) and in females it was 463/709 (65.3%). The prevalence of H.pylori infection was significantly higher (77.0%) in patients whose age is greater than 60 years and the lowest positive age group was between 0–20 in which only 59.1% were positive (X2 =14.15,p=0.0146). The seroprevalence was 86.5% in 2009 and it decreased to 51.8% in 2010. But the seroprevalence increased to 61.3% in 2011. Conclusion This study showed high seroprevalence of H .pylori among the dyspeptic patients in GUH. The trend of the seroprevalence was varied from year to year in the three consecutive years. In general it showed that the seroprevalence has started increasing.

Abstract
PURPOSE To compare the prevalence of chronic atrophic gastritis (CAG) in Japan, China, Tanzania, and the Dominican Republic and to assess the usefulness of Helicobacter pylori infection and serum gastrin level as markers of CAG. METHODS The subjects were volunteers from local communities in Japan (n=859), China (n=1741), Tanzania (n=573), and the Dominican Republic (n=1215). Each individual underwent a health checkup and blood sampling for measurement of serum pepsinogen I and II, pepsinogen I /II ratio, serum gastrin, and H. pylori antibodies, and responded to a questionnaire on upper digestive tract diseases. RESULTS The prevalences of H. pylori infection (23.5-96.1%), CAG (5.6-60.4%), and serum gastrin (62.0-136.5 pg/ml) varied by age, sex, and country. Serum gastrin level for men differed in each country according to age. In Tanzanian men, the median gastrin level (101.0 pg/ml) was the highest in the 40 to 49 years age group (p < 0.01) while there was no significant difference among different age groups in Tanzanian women. Serum gastrin level in subjects > or = 70 years was higher than in other age groups in both sexes in the Dominican Republic (males, 92.5, females, 136.5 pg/ml). The prevalence of H. pylori infection increased (p < 0.01) with advancing age in Japan (only for women) and the Dominican Republic but was high in all age groups of both sexes in China and Tanzania. The prevalence of CAG increased (p < 0.01) with age in both sexes in Japan, China (women only), and the Dominican Republic, but not in Tanzania. The odds ratio of CAG in H. pylori infected subjects was 5.3 times that in H. pylori-negative subjects. The odds ratio of CAG increased by 0.6%/1 pg/ml increase in serum gastrin. CONCLUSIONS Our results indicated that H. pylori infection, serum gastrin, and advancing age are good markers of CAG and that the prevalence of CAG is the highest in Japan.

Abstract
OBJETIVO: Medir a prevalência e distribuição de dispepsia e dispepsia freqüente por subtipos na população com 20 anos ou mais segundo características socioeconômicas e demográficas. MÉTODOS: Estudo transversal, de base populacional, com 3.934 indivíduos moradores na cidade de Pelotas (RS), entrevistados em seus domicílios, de outubro de 1999 a janeiro de 2000. Dispepsia foi definida como dor ou desconforto no andar superior do abdome e/ou náuseas no ano anterior à entrevista (conforme critérios Roma I e II). Dispepsia freqüente incluiu o registro de dispepsia mais de seis vezes e/ou náuseas, uma vez por mês ou mais. Esses desfechos foram analisados por idade, sexo, cor da pele, escolaridade, renda e estado civil. Os dados foram analisados por meio do teste qui-quadrado de Pearson de associação para variáveis categóricas e teste de tendência linear, quando aplicável. RESULTADOS: A prevalência de dispepsia foi de 44,4% e de dispepsia freqüente, 27,4%. A prevalência de dispepsia tipo refluxo, úlcera, dismotilidade e não especificada foi, respectivamente, 19,4%, 6,3%, 13,9% e 16,6%; para dispepsia freqüente foram 14,7%, 4,9%, 11,2% e 6,8%, respectivamente. As mulheres apresentaram cerca de 50% mais dispepsia freqüente. Indivíduos mais jovens e de menor renda apresentaram maiores prevalências de dispepsia e dispepsia freqüente. Análise de acordo com critérios de Roma II mostrou prevalências de 15,9% e 7,5% para dispepsia e dispepsia freqüente, respectivamente. CONCLUSÕES: A dispepsia constitui um problema prevalente na população estudada. A maioria dos indivíduos apresentaram mais de um subtipo de dispepsia.

Abstract
BACKGROUND Helicobacter pylori infection is primarily acquired in early childhood. Its transmission routes are debated. The aims of this study were to determine the seroprevalence of anti-H. pylori immunoglobulin G (IgG) in Yemeni children under 10 years of age, the potential risk factors for contracting H. pylori infection and co-infection of H. pylori with intestinal parasites. METHODS Enzyme-labeled immunosorbent assay was used to determine the H. pylori prevalence rate among 572 healthy volunteers aged less than 10 years. Formalin ether concentration methods were used to test the prevalence of intestinal parasites (intestinal roundworms and tapeworms). In addition, we interviewed participants regarding potential risk factors for contracting H. pylori infection. RESULTS The seroprevalence of H. pylori antibodies was 9%. The prevalence according to age varied from 0% in children under 2 years to 12.5% in age group 9-10 years. There was a correlation between the amounts of positive antibodies and increasing age. The prevalence rate of H. pylori antibodies was also significantly associated with the practice of drinking water from reused plastic jerry cans, with poor mouth hygiene and with co-infection by intestinal parasites. CONCLUSION The prevalence of H. pylori antibodies in Yemen among children under 10 years of age is higher than that reported from other regions for the same age groups. Yemen shares some but not all potential risk factors for H. pylori infection with countries in which similar socioeconomic conditions are found. A possible way of eliminating H. pylori from the population would be via public health measures, i.e. preventing the reuse of plastic jerry cans, and improving sanitation and the standard of living.
