Abstract
Helicobacter pylori and intestinal parasites cause gastrointestinal diseases with a high prevalence in children in resource limited developing countries. There is paucity of information in Nigeria on co-infection of H. pylori and intestinal parasites. The study was conducted to determine the prevalence of H. pylori and parasite co-infection in children from selected low-income communities in Lagos, Nigeria. Fecal samples were collected from 151 healthy children aged ≤11 years across six low-income communities in Lagos. H. pylori was detected using stool antigen test and conventional PCR assay, intestinal parasites were detected using formol-ether concentration and nested PCR assay. Structured questionnaires were administered to parents and legal guardians of the children by an interviewer to collect relevant data on demographic and lifestyle factors. The prevalence of H. pylori was 31.79% (48), with a higher prevalence in children aged 2-3 years. The prevalence of intestinal parasites was 21.19% (32) with the lowest frequency found in children aged 8-9 years. The parasites detected include: A. lumbricoides (10.6%), G. intestinalis (7.3%), hookworm (1.99%), E. histolytica (0.66%), S. mansoni (0.66%). There was co-infection prevalence of 10.6% (16) which was associated with the parasites: G. intestinalis (7.3%) and A. lumbricoides (3.97%). Polyparasitism with G. intestinalis and A. lumbricoides was reported in 2 children infected with H. pylori. This study which is the first reported in Lagos established a low prevalence of H. pylori and intestinal parasite co-infection in children and provides better understanding of the epidemiology of H. pylori infection associated with intestinal parasites in Nigeria.

Prevalence of Helicobacter pylori infection and effectiveness of first-line triple eradication therapy among dyspeptic patients at hospitals in Hawassa City, Ethiopia: a cross-sectional follow-up study. Gut Pathog 2024; 16:23. [PMID: 38678267 PMCID: PMC11056052 DOI: 10.1186/s13099-024-00618-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Accepted: 04/19/2024] [Indexed: 04/29/2024] Open
Abstract
BACKGROUND Dyspepsia is a common gastrointestinal illness sometimes associated with Helicobacter pylori (H. pylori) infection. Screening and eradicating the bacterium reduces the risk of infection-related complications. The aim of this study was to determine the magnitude of H. pylori infection among dyspeptic patients and the effectiveness of triple eradication therapy at hospitals in Hawassa city, Ethiopia. RESULTS The prevalence of H. pylori infection was 48.5%. The H. pylori eradication rate using first-line triple therapy was 83.8%. Eradication therapy failure is associated with previous exposure compared to no exposure (AOR: 4.8, 95% CI: 1.37-10.97), a regimen for 10-days compared to 14-days (AOR: 4.05, 95% CI: 1.42-11.55), and self-reported side effects compared to no report (AOR: 2.5, 95% CI: 1.12-5.97). Based on Morisky-eight scale 230 (79.0%) patients were adherent to their triple therapy. Participants with no reports of adverse effects showed increased odds of adherence to triple therapy compared to those who had reports (AOR = 2.45, 95% CI: 1.29-4.62). CONCLUSIONS This study demonstrated that about half of adult dyspeptic patients were infected with H. pylori, and moderate eradication was observed. Factors such as previous history of eradication therapy, duration of the eradication regimen, and perception of potential adverse effects are associated with eradication rate and should be considered during the initiation of eradication therapy.

Abstract
BACKGROUND AND AIM Gastritis and duodenitis, prevalent diseases of the digestive system, impose a significant global burden. This study aimed to examine their incidence and prevalence patterns worldwide, including changes over the past 30 years. METHODS The age-standardized incidence rate (ASIR) and age-standardized prevalence rate (ASPR) of gastritis and duodenitis, stratified by age, sex, geographical region, and sociodemographic index (SDI), were obtained from the Global Burden of Disease 2019. The dynamic trends were captured by calculating the average annual percentage changes (AAPC). RESULTS In 2019, the global ASIR and ASPR of gastritis and duodenitis were 379.88/100 000 (95% uncertainty interval [UI]: 312.42/100 000-448.12/100 000) and 518.11/100 000 (95% UI: 420.62/100 000-631.66/100 000), respectively. The highest rates were observed among the 50-69 age group (ASIR: 856.48/100 000; ASPR: 1158.04/100 000) and in low SDI regions (ASIR: 443.33/100 000; ASPR: 631.22/100 000). From 1990 to 2019, there was a significant decrease in global ASIR (AAPC = -0.34%, 95% confidence interval [CI]: -0.36% to -0.31%) and ASPR (AAPC = -0.34%, 95% CI: -0.37% to -0.31%) of gastritis and duodenitis. However, ASIR (AAPC = 0.47%, 95% CI: 0.42%-0.52%) and ASPR (AAPC = 0.51%, 95% CI: 0.47%-0.52%) of gastritis and duodenitis experienced a significant increase in low SDI regions. CONCLUSIONS Despite a significant decrease in the global incidence and prevalence of gastritis and duodenitis, these conditions continue to impose a burden on individuals aged 50-69 years and low SDI regions. Targeted interventions for those specific populations and regions are necessary.

Abstract
BACKGROUND There is a widespread co-infection of HIV and Helicobacter pylori (H. pylori) globally, particularly in developing countries, and it has been suggested that this co-infection may affect the course of HIV disease. However, the interplay between H. pylori infection and HIV disease progression is not fully elucidated. In this study, we investigated the effect of H. pylori co-infection on CD4+ T cell count and HIV viral load dynamics in HIV-positive individuals in a high co-endemic setting. METHODS A comparative cross-sectional study was conducted among 288 HIV-positive and 175 HIV-negative individuals, both with and without H. pylori infection. Among HIV-positive participants, 195 were on antiretroviral therapy (ART) and 93 were ART-naïve. CD4+ T cell count and HIV-1 viral load were measured and compared between H. pylori-infected and -uninfected individuals, taking into account different HIV and ART status. RESULT Our study demonstrated that individuals infected with H. pylori had a significantly higher CD4+ T cell count compared to uninfected controls among both HIV-negative and HIV-positive participants, regardless of ART therapy. Conversely, HIV/H. pylori co-infected participants had lower HIV-1 viral load than those without H. pylori infection. Linear regression analysis further confirmed a positive association between H. pylori infection, along with other clinical factors such as BMI, ART, and duration of therapy, with CD4+ T cell count while indicating an inverse relationship with HIV-1 viral load in HIV-positive patients. Additionally, factors such as khat chewing, age and WHO clinical stage of HIV were associated with reduced CD4+ T cell count and increased HIV-1 viral load. CONCLUSION Our study demonstrates that H. pylori co-infection was associated with higher CD4+ T cell count and lower HIV-1 viral load in HIV-positive patients, regardless of ART status. These findings show a positive effect of H. pylori co-infection on the dynamics of HIV-related immunological and virological parameters. Further studies are needed to elucidate the underlying mechanisms of the observed effects.

Abstract
BACKGROUND Helicobacter pylori is the main cause of chronic gastritis, peptic ulcer, lymphoma, and gastric cancer in humans. The prevalence and factors associated with H. pylori infection are varied across countries. Thus, a comprehensive review has not been done on prevalence and associated factors in East Africa. Therefore, this systematic review and meta-analysis aimed to estimate the pooled prevalence and identify factors associated with H. pylori infection in East Africa. METHODS Articles written in English language were retrieved from PubMed, Scopus, and Science Direct. Relevant articles were selected and screened using Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Publication bias was assessed qualitatively and qualitatively using funnel plot symmetry and Egger's test, respectively. Heterogeneity was assessed using the I2 measure. Data were analyzed using Stata software, version 14, and the "metan" command. RESULTS A total of 231 articles were retrieved from nineteen countries in East Africa. Of these, 70 articles were eligible for the review. The pooled prevalence of H. pylori in East Africa was 50.98% (95% CI: 45.05-56.90). The prevalence of H. pylori infection ranged from 7.7 to 94.5% in East African countries. The highest pooled prevalence was from Sudan (61.3%, 95% CI: 52.6-69.9), and the lowest prevalence was reported from Uganda (40.7%, 95% CI: 33-48.3). Persons with no formal education (OR: 2.03; 95% CI: 1.22-2.83), lack of hand washing habit after toilet (OR: 2.24; 95% CI: 1.45-3.02), having a history of dyspepsia (OR: 2.25; 95% CI: 1.31-3.18), living in rural areas (OR = 1.80; 95% CI: 0.38-3.23), and having unclean water source (OR = 1.5; 95% CI:0.45-3.45) were all associated with higher risk for H. pylori infection. CONCLUSION More than half of the populations of East African countries were positive for H. pylori infection. Rural residence, source of water, and alcohol consumption were significantly associated with H. pylori infection. Therefore, healthcare workers could provide health education on the aforementioned risk factors, and the government and other stakeholders could improve the source of drinking water in East Africa.

Abstract
Background Around half of the world's population is infected with Helicobacter pylori (H. pylori), according to data from a recent systematic review. H. pylori infection is extremely common around the world. It is the most prevalent disease in Ethiopia and contributes to both morbidity and mortality. Patients with gastritis, peptic ulcers, and stomach cancer have been reported to harbor H. pylori. Objective The aim of this study was to determine the trends of Helicobacter Pylori infection among patients attending the Bule Hora University Teaching Hospital from 2018-2022, Bule Hora, Ethiopia. Method A hospital-based retrospective study design was conducted to recruit 314 sampled data from the logbook, which were five-year data (2018-2022) from the Bule Hora University Teaching Hospitals. Data were extracted using structured checklists. The sample size was calculated using the single-population proportion formula. Study participants were selected using a systematic random sampling technique. Data were entered in EpiData 4.6 and exported to SPSS Version 26 for analysis. Results Approximately 314 complete data from selected participants were collected and evaluated for the present study. The mean age was 29.01 (SD ± 4.93). Most of the respondents (39.2%) were in the age group of 21 to 30 years. The general prevalence of H. pylori observed in this study is 28% (95% confidence interval [CI], 23-32.9). The prevalence was higher in women (71.6%) than in men (28.4%). In terms of age category, those over 60 years of age were observed with the highest positiveness for H. pylori with 38.1% and the trend of H. pylori prevalence fluctuated from 2018 to 2022. Conclusion In total, 28% of the study participants had H. pylori, but there was variation in the prevalence of H. pylori infection between 2018 and 2022. Compared to other age groups, the 60-year-old age group had a higher prevalence of H. pylori and this prevalence continued to increase annually. The concerned parties must be interested in raising awareness and establishing criteria for the eradication of these bacteria.

Abstract
Background Gastrointestinal disease is a significant global health problem. Symptoms related to digestive system diseases negatively affect quality of life and impose a significant economic impact. Upper gastrointestinal symptoms are common in the Ethiopian population, and the associated pathologies are diverse. Real-time endoscopic visualization of the upper gastrointestinal tract is crucial for diagnosis. However, local data on the indications for endoscopic evaluation and the common underlying pathologies are limited. This study aimed to assess the common indications and upper gastrointestinal endoscopic findings of patients presenting to Saint Paul's Hospital Millennium Medical College, Addis Ababa, Ethiopia. Methods A cross-sectional study was conducted by reviewing the complete records of patients who underwent upper gastrointestinal endoscopic evaluation between January 2012 and December 2019. A structured checklist was used to screen records for completeness. Data were analyzed using Statistical Package for the Social Sciences software version 25. Chi-square test was used to compare variables, with statistical significance set at P < 0.05. Results A total of 5753 patients underwent complete upper gastrointestinal tract endoscopic evaluation during the study period. The median age of the patients was 37 years. Males accounted for 63.4% of the patients. Dyspepsia (27.8%) was the most common indication for upper gastrointestinal endoscopic evaluation, followed by upper gastrointestinal bleeding (17.1%), and screening for varices (16.8%). Esophageal varices (35.8%), gastritis (18.1%), and duodenal ulcers (10.6%) were the most common pathologies found on esophagus, stomach, and duodenum, respectively. Common upper gastrointestinal pathologies are predominant among males and patients in their third decade of life. Conclusion Dyspepsia was the most common indication for endoscopic evaluation of the upper gastrointestinal tract. Esophageal varices were the most common pathological finding, followed by gastroesophageal reflux disease, gastritis, portal hypertensive gastropathy, duodenal ulcer, and hiatal hernia. Esophagogastroduodenoscopy remains a vital tool for the diagnosis of pathologies of the upper gastrointestinal tract.

Abstract
Background Most gastric cancers in the world are attributed to Helicobacter pylori (H. pylori) infections. The prevalence of H. pylori infection is influenced by socioeconomic status, hygiene, and lifestyle of the population. This study aimed to assess sero- and feco-prevalence of H. pylori infections and its associated risk factors among adult dyspeptic patients visiting the outpatient department of Adet Primary Hospital, Yilmana Densa District, northwest Ethiopia. Methods A hospital-based cross-sectional study was conducted from February 10, 2022 to April 10, 2022. The study participants were selected using a systematic random sampling technique. The data were collected by pretested questionnaires. Blood and stool specimens were collected from each patient for antibody and H. pylori antigen tests, respectively. The data were analyzed using Statistical Package for Social Science (SPSS) version 26.0. A logistic regression model was used to assess the strength of association between H. pylori positivity and risk factors. Results The sero- and feco-prevalence of H. pylori infection was 62% and 51.1%, respectively. In those patients who had a positive result with either the antibody (Ab) or antigen (Ag) test, rural residence (AOR = 5.55; 95% CI: 2.34-13.14; p < 0.001), alcohol consumption (AOR = 12.34; 95% CI: 2.29-66.51; p=0.003), having no awareness about H. pylori transmission (AOR = 4.76; 95% CI: 1.86-12.15; p=0.001), using pond/river as a source of drinking water (AOR = 5.22; 95% CI: 1.91-14.27; p=0.001), and open field defecation (AOR = 4.19; 95% CI: 1.67-10.52; p=0.002) were the explanatory risk factors significantly associated with H. pylori infection. Conclusion This study showed that the prevalence of H. pylori infection was very high. Most cases of gastric cancers are ascribed to H. pylori infection. Therefore, education should be given to communities so as to increase their awareness of the infection and the associated major explanatory risk factors identified in the present study.

Abstract
BACKGROUND Infesting nearly half of the world's population, Helicobacter pylori is thought to cause peptic ulcers and gastric adenocarcinoma. Several studies have examined the association between H. pylori and socioeconomic, clinical, and histological factors in pediatric populations. Similarly, this study aimed to describe the characteristics of H. pylori infection in Moroccan children. METHODS Patients aged 1-17 years who underwent upper gastrointestinal endoscopy over a period of two years from January 2019 to January 2021 were included in this study. Gastric biopsies from the antrum and corpus of the stomach were collected. Detection of H. pylori infection was confirmed by Giemsa stain. Demographic data and clinical and endoscopic characteristics were collected and histopathological findings with gastritis scoring were recorded according to the Sydney System. RESULTS In 213 children, 95 (45%) were found to be infected with H. pylori, and the infection rates increased as the children aged. While no significant relationship between the infection of H. pylori and all symptoms was founded, a significant association was found in nodular gastritis (p<0.05), and 98% of the infected children had chronic inflammation, which was active in 22% and atrophic in 47%. The atrophy and activity were absent or mild, and the inflammation was mild to moderate. CONCLUSION According to this study, nodular gastritis and nonspecific symptoms were related to H. pylori infection in Moroccan children. In addition, the association between this disease and gastric atrophy in our study needs the monitoring of the mucosa of Moroccan children with gastritis and identifying factors that may contribute to gastric cancer.

Proportion of hyperemesis gravidarum and associated factors among pregnant women admitted into the obstetrics ward at Akesta general hospital, North East Ethiopia. PLoS One 2023; 18:e0281433. [PMID: 36745599 PMCID: PMC9901745 DOI: 10.1371/journal.pone.0281433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Accepted: 01/23/2023] [Indexed: 02/07/2023] Open
Abstract
INTRODUCTION Hyperemesis gravidarum is a condition of intractable vomiting during pregnancy that leads to fluid and electrolyte imbalance, nutrition deficiency and weight loss often requiring hospital admission. Approximately 0.3%-10.8% of pregnant women experience nausea and vomiting during the first trimester of pregnancy. It has been associated with both maternal and fetal morbidity. There is limited evidence about the proportion of hyperemesis gravidarum and associated factors in the study area. OBJECTIVE The aim of this study was to determine the proportion of hyperemesis gravidarum and associated factors among pregnant women admitted into the obstetric ward at Akesta General Hospital, South Wollo Zone, Ethiopia. METHODS This is hospital-based cross-sectional study of 355 pregnant mothers in Akesta general hospital in northeast Ethiopia from September 1/2018- to August 30 /2020. A simple random sampling technique was used to select the patient card from the whole admission of pregnant women cards during the study period. The diagnosis of hyperemesis gravidarum include persistent vomiting not related to other causes, an objective measure of acute starvation, electrolyte abnormalities and acid-base disturbances, as well as weight loss. The data analysis was done using SPSS version 25. Bivariable and multivariable binary logistic regression analysis was conducted to identify factors associated with hyperemesis gravidarum. Adjusted odds ratio (AOR) with 95% confidence intervals (CI) was reported to show the strength of the association. Statistical significance was stated at P-value < 0.05. RESULTS The proportion of hyperemesis gravidarum was 11.3%. Women with previous history of hyperemesis gravidarum AOR (95%CI) = 10.9[2.46, 48.44], previous history of urinary tract infection AOR (95%CI) = 4.32[1.58, 11.86], previous history of gastrointestinal disease AOR (95% CI) = 4.12[1.40, 12.65], history of abortion AOR (95% CI) = 6.23[2.24, 17.52] were factors significantly associated with hyperemesis gravidarum. CONCLUSION In this study, the overall hospital proportion of hyperemesis gravidarum was high. History of gastrointestinal disease, previous history of urinary tract infection, history of hyperemesis gravidarum, and history of abortion were the major risk factors.

Dinat S, Orchard A, Van Vuuren S. A scoping review of African natural products against gastric ulcers and Helicobacter pylori. JOURNAL OF ETHNOPHARMACOLOGY 2023; 301:115698. [PMID: 36174808 DOI: 10.1016/j.jep.2022.115698] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 08/25/2022] [Accepted: 09/02/2022] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE African traditional medicine is one of the oldest and most diverse practices for treating ailments and numerous natural products have been recommended for gastric ulcer treatment. Helicobacter pylori is the main causative organism implicated in several diseases, most notably in causing inflammation and the onset of gastric ulcers. Current H. pylori treatment methods are losing efficacy as H. pylori rapidly gains resistance to antibiotics. Hence, a search into natural products and their historical traditional efficacy for the treatment of gastric ulcers is of interest. AIM OF THE STUDY This review aimed to summarise the African use of natural products, including medicinal plants noted in ethnobotanical reviews, used traditionally to treat gastric ulcers, and highlights the investigations into the anti-H. pylori activity of medicinal plants and bee products found in Africa. METHODOLOGY A systematic review was carried out to identify natural products, including those used traditionally in Africa to treat gastric ulcers, and to correlate this with scientific investigations into the anti-H. pylori activity of natural products used in Africa. RESULTS A total of 107 literature sources describing the traditional use of medicinal plants in gastric ulcer treatment were found, from which 360 medicinal plants were identified. Of the plants used traditionally for gastric ulcer treatment, 11% were investigated either in vitro or in vivo for anti-ulcer and anti-H. pylori activity. Of the 122 medicinal plants eliciting antimicrobial or anti-ulcer activity, Hibiscus sabdariffa L. calyx extract and Terminalia macroptera Guill. & Perr. root extract were found to have the most noteworthy antimicrobial activity, with minimum inhibitory concentrations (MICs) of 0.01 mg/mL and 0.03 mg/mL respectively. The essential oils of Piper longum L. and Pachira aquatica Aubl. displayed the most notable in vitro anti-H. pylori activity (MIC of 0.01 mg/mL and 0.02 mg/mL). Several in vivo studies found medicinal plant extracts effective in reducing the H. pylori load along the gastric mucosa. The South African honey variants, Pure Honey and Champagne Royal Train (common names given by supplier) were the most antimicrobially effective (MIC of 0.01-10.0%, 0.63-10.00% v/v) in inhibiting H. pylori when assessed in vitro. CONCLUSION These results highlight the potential of natural products to inhibit H. pylori growth and serve as a possible stepping-stone in understanding the management of ulcers. Furthermore, effective natural product treatment or prophylactic use for preventing H. pylori growth may provide a more affordable option for African populations.

Abstract
BACKGROUND Depression is the most common mental health problem, and frequently associated with physical illnesses. A link between depression, dyspepsia and Helicobacter pylori (H. pylori) infection has previously been reported. However, there is limited data regarding the association between these conditions from sub-Saharan Africa where they are highly prevalent. OBJECTIVE This study aimed at elucidating the potential associations between depression, dyspepsia and H. pylori infection in Ethiopia. METHODS We conducted a community based cross-sectional study involving urban and rural residents aged 13 years or older in Jimma Zone, southwest Ethiopia. A total of 871 participants were evaluated using a structured case reporting format for symptoms of dyspepsia and the patient health questionnaire (PHQ-9) for depression. Additionally, participants were assessed for H. pylori infection using stool antigen and serology tests. A multivariate logistic regression was used to identify the association between depression, dyspepsia and H. pylori infection after controlling for potential confounders. RESULTS The prevalence of PHQ-9 scores indicative of probable case of depression among all participants was 10.9%. The prevalence of probable case of depression among patients who had at least one symptom of dyspepsia was 13.3% (X2 = 15.1 = p-value<0.001), while it was 11.9% (X2 = 1.23, p-value = 0.26) among patients who had H. pylori infection. Out of patients who took medications for their heartburn in the past 30 days, 14.9% (X2 = 3.6, p-value = 0.06) had probable case of depression. Dyspepsia symptoms such as epigastric discomfort (aOR = 2.59, 95%CI = 1.14, 5.87), postprandial fullness (aOR = 1.70, 95%CI = 1.48, 5.51), nausea (aOR = 1.71, 95%CI = 1.04, 2.82) excessive belching (aOR = 0.53, 95%CI = 0.31, 0.92) were associated with probable case of depression. However, being H. pylori test positive, gender, and age were not associated with probable case of depression. CONCLUSIONS There was an increased prevalence of probable case of depression among patients who had dyspepsia symptoms and H. pylori infection. Longitudinal studies are needed to examine possible further determinants of association between symptoms of dyspepsia and probable case of depression.

Borka Balas R, Meliț LE, Mărginean CO. Worldwide Prevalence and Risk Factors of Helicobacter pylori Infection in Children. CHILDREN 2022; 9:children9091359. [PMID: 36138669 PMCID: PMC9498111 DOI: 10.3390/children9091359] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/07/2022] [Revised: 08/22/2022] [Accepted: 09/03/2022] [Indexed: 01/17/2023]
Abstract
Helicobacter pylori is usually acquired during childhood. The reports from the last two decades pointed out a decrease in H. pylori prevalence across geographical areas worldwide compared to previously reported data. Most of the studies performed in America found an overall H. pylori infection prevalence of approximately 50%. The most important risk factors in America include being male, poor adherence or difficult access to treatment, and the lack of in-home water service. Despite the descending trend in prevalence worldwide, the overall prevalence in Africa remains very high (70%). Nevertheless, the prevalence of H. pylori in children without gastrointestinal who underwent screening was reported to be only 14.2%. The main risk factors in Africa are having a traditional pit or no toilet, poverty, birth order, source of drinking water, or being a farmer. Asia seems to have the widest variations in terms of H. pylori prevalence. Several risk factors were reported in Asia to be associated with this infection, such as lower income and educational level, house crowding, rural residence, ethnicity, the use of tanks as water supplies, alcohol drinking, active smoking, eating spicy food or raw uncooked vegetables, poor living conditions and sanitation. The overall prevalence of H. pylori infection in European children is almost 25%. Portugal has the highest prevalence of all European countries at 66.2% in children 13 years of age. The risk factors in European individuals consist of living in rural areas, eating unwashed fruits and vegetables, not washing hands after school, low parental education and unemployment, and short education duration. Further studies are required to identify the precise mechanisms involved in the discrepancies of H. pylori prevalence worldwide.

Abstract
BACKGROUND In resource-constrained countries, accurate diagnosis of Helicobacter pylori infection remains a challenge. This study aimed to assess the clinical utility of locally available serological and stool antigen test kits in the management of people with suspected H. pylori infection in Ethiopia. METHODS A community-based cross-sectional study was conducted with apparently healthy adults and children living in southwest Ethiopia. Participants were interviewed for dyspepsia symptoms and related clinical conditions. H. pylori infection was examined using commercially available serological and stool antigen tests. The association between H. pylori tests and dyspepsia symptoms was analyzed using logistic regression models. RESULTS Out of 1392 participants included in the final analysis, 49.1% and 6.5% tested positive for H. pylori infection with serology and stool antigen test kits, respectively. Participants reporting epigastric symptoms in the past three months (AOR = 1.93, 95% CI = 1.28-2.91) and those with recent dyspepsia treatment (AOR = 1.51, 95% CI = 1.05-2.18) were likely to have positive serology test. However, no association between dyspepsia symptoms and H. pylori stool antigen positivity was observed in our study. CONCLUSION ccurate detection of H. pylori infections using commercially accessible diagnostics remains difficult in Ethiopia. With these methods, it will be hard to ensure adequate diagnosis and early treatment of H. pylori infection, as well as rational antibiotic use.

Abstract
Background Helicobacter pylori infections are associated with many complications of pregnancy including preeclampsia. It has been suggested that H. pylori infection could contribute to the etiopathogenesis of preeclampsia by inducing a pro-inflammatory state. Objective To assess the magnitude of H. pylori infection and its association with preeclamptic and non-preeclamptic pregnant women attending antenatal care in Ethiopia. Methods Hospital-based case control study was conducted among clinically diagnosed preeclamptic and non-preeclamptic pregnant women. Stool samples were collected for H. pylori antigen test from study participants. The collected data were analyzed using statistical methods in SPSS version 23. Simple descriptive statistics were used to present the socio-demographic and clinical characteristics of the study subjects. Association between clinical variables, preeclampsia and H. pylori infection was performed with multivariate logistic regression. A p-value of <0.05 at 95% confidence level was considered as statistically significant in all the analyses. Results A total of 93 cases and 186 controls were included in this study. The overall prevalence of H. pylori infection in all study participants was 38.9% (16/272). The prevalence of H. pylori infection was higher in cases than controls, 54.3% (50/92) vs 31.1% (56/180), respectively. The mean age was 29.01 (SD±4.93) years in cases and 30.37 (SD± 6.2) years in control group. A positive association was found between H. pylori infection and preeclampsia (OR: 2.45; 95% CI: 2.41–4.10). Conclusion H. pylori infection has been found to be associated with preeclamptic pregnant women. In this study, the prevalence of H. pylori infection was higher in cases than in controls. Age group, educational status, occupational status and body mass index were significantly associated with preeclamptic women with H. pylori. The association of H. pylori with preeclampsia needs to be further explored.

Abstract
Background Studies showed that more than half of Ethiopians were presumed to be chronically infected with H. pylori. Nowadays, evidence has come to the literature strongly suggesting the potential association between H. pylori and extra gastric disorders including atherosclerosis. Objective To assess the association of helicobacter pylori infection with dyslipidaemia and other atherogenic factors in dyspeptic patients at St. Paul's Hospital Millennium Medical College, from November 2019 to June 2020. Materials and methods This institution-based cross-sectional study was examining 346 dyspeptic patients at SPHMMC from November 2019 to June 2020. A structured questionnaire was used to collect socio-demography data and anthropometric measurement was taken. Biochemical parameters were measured in serum samples by using Cobas 6000 clinical chemistry analyzer. Data were coded and entered into a statistical package for social sciences (SPSS) version 23 for analysis. Risk factors were identified using logistic regression. Hence, a bivariate logistic regression analysis test was conducted and variables with a p < 0.25 were included in the multivariate logistic regression model. P-values ≤0.05 were considered as a cut point for statistical significance in the final model. Results An overall prevalence of dyslipidemia among study participants was 253 (73.12 %). Among those who tested positive for H. pylori, 119/174 (68.39 %) had dyslipidemia in at least one lipid profile, while 8 (4.60%) had dyslipidemia in all four lipid profiles. After adjusting for traditional dyslipidemia risk factors, age >45 (AOR 4.864, 95% CI 2.281–4.080, P < 0.001), systolic blood pressure >120mmHg (AOR 1.036, 95% CI 1.009–1.065, P = 0.036) and being H. Pylori seropositive (AOR 0.555, 95% CI 0.318–0.967, P = 0.038) were an independent predictors of dyslipidemia. Conclusion This study reported that more than two-thirds of the H. pylori seropositive groups had exhibited dyslipidemia in at least one lipid profile, which can accelerate the incidence of atherosclerosis process.

Abstract
Background Dyspepsia is a common complaint in upper gastrointestinal disorders. It is described as predominant epigastric pain lasting for at least one month. Globally, peptic ulcer disease occurs in 3.5–32% of patients with dyspepsia. Helicobacter pylori (H. pylori) infection and non-steroidal anti-inflammatory drugs/aspirin use are the widely known risk factors for peptic ulcer disease. There was no recent document on H. pylori infection rate among patients with peptic ulcer disease in Ethiopia. This study aimed to determine magnitude and associated factors of peptic ulcer disease among dyspeptic patients in Northwest Ethiopia. Methods An institutional-based cross sectional study was conducted at the University of Gondar hospital, Northwest Ethiopia. A convenience sampling method was used to recruit 218 study subjects. A pre-designed semi-structured questionnaire was used to extract clinical information. Olympus flexible fiber-optic endoscope (Olympus, GIF-E 600, Olympus Corp., Hamburg, Germany) was used to confirm the presence of peptic ulcer disease. Diagnosis of active H. pylori infection was made using the fecal H. pylori Antigen 25 T Card Test (Anamol Lab., Pvt. Ltd., Palghar, India). The Data were entered into EPI Info version 4.6.0.2, and then exported to SPSS version 20 for analysis. Explanatory variables associated with peptic ulcer disease were analyzed by applying logistic regression model. P value < 0.05 was used to declare significant association.
Result A total of 218 dyspeptic patients who underwent upper gastrointestinal endoscopic evaluations were included in the study. The mean (+ SD) age of patients was 42 ± 16.4 years. Forty nine percent (95% CI 42.4–56.2) of dyspeptic patients had active H. pylori infection. Peptic ulcer disease was diagnosed in 35% (95% CI 31.4–39.2) of patients with dyspepsia. H. pylori infection (AOR = 6.298, 95% CI 2.965–13.378, P value < 0.001) and NSAIDs/ASA use (AOR = 6.252, 95% CI 2.925–13.362, P value < 0.001) were identified as risk factors for peptic ulcer disease. Conclusion Medical treatment of peptic ulcer disease should target treatment of H. pylori infection and cautious use of non-steroidal anti-inflammatory drugs/aspirin.

Abstract
INTRODUCTION Gastro-esophageal reflux disease (GERD) is a common gastrointestinal disorder that occurs when backflow of the gastric contents into the esophagus results in troublesome symptoms. Though GERD has been extensively studied in Western populations, literature on the management of GERD in patients in Africa and Middle East (AME) is scarce. AREAS COVERED In this review, we provide an overview of the management of mild-to-moderate GERD in AME. Here we focus on the efficacy and safety of currently available treatments for GERD to help physicians and community pharmacists appropriately manage patients with mild-to-moderate GERD in the primary healthcare setting, detailing specific situations and patient scenarios that are relevant to the region, including management of GERD during Ramadan and post-bariatric surgery. EXPERT OPINION Under-appreciation of the burden of GERD in the region has resulted in a lack of consensus on management. Barriers that currently prevent the adoption of treatment guidelines in the primary healthcare setting may include lack of availability of local guidelines and referral systems, a paucity of region-specific research, and dogmatic adherence to traditional practice. By increasing awareness, strengthening knowledge, and by more effective utilization of resources, physicians and pharmacists could optimize GERD management strategies to better support patients.

Ren S, Cai P, Liu Y, Wang T, Zhang Y, Li Q, Gu Y, Wei L, Yan C, Jin G. Prevalence of Helicobacter pylori infection in China: A systematic review and meta-analysis. J Gastroenterol Hepatol 2022; 37:464-470. [PMID: 34862656 DOI: 10.1111/jgh.15751] [Citation(s) in RCA: 77] [Impact Index Per Article: 38.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 11/05/2021] [Accepted: 11/18/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND AND AIM Helicobacter pylori (H. pylori) infection rates have been changing with different populations and geographic areas. We systematically evaluated the longitudinal trends in H. pylori prevalence in China over the past decades. METHODS We performed a systematic review of literature reporting the prevalence of H. pylori infection in mainland China from 1990 to 2019 in the PubMed and China National Knowledge Infrastructure databases. We conducted a meta-analysis of qualified studies using a random effects model to estimate the pooled prevalence with a 95% confidence interval (95%CI). RESULTS A total of 412 eligible studies with 1 377 349 subjects were included. The pooled H. pylori prevalence was 44.2% (95%CI: 43.0-45.5%) in mainland China, with an estimated 589 million individuals infected with H. pylori. The prevalence was relatively high in the Northwest (51.8%, 95%CI: 47.5-56.1%), East (47.7%, 95%CI: 45.4-50.0%), and Southwest China (46.6%, 95%CI: 42.1-51.1%). The prevalence significantly decreased from 58.3% (95%CI: 50.7-65.5%) in the period 1983-1994 to 40.0% (95%CI: 38.2-41.8%) in the period 2015-2019. The prevalence increased with age, ranging from 28.0% (95%CI: 23.9-32.5%) in children and adolescents to 46.1% (95%CI: 44.5-47.6%) in adults. CONCLUSION Although the burden of H. pylori infections is still huge in China, the infection rate has been decreasing over the past decades. Targeted H. pylori eradication strategies may be considered in areas or populations with a high incidence of gastric cancer.

Prevalence of H. pylori among asymptomatic HIV-positive and negative individuals in Central Ethiopia and efficacy of eradication therapy. IJID REGIONS 2022; 2:169-174. [PMID: 35757079 PMCID: PMC9216691 DOI: 10.1016/j.ijregi.2022.01.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 12/24/2021] [Accepted: 01/14/2022] [Indexed: 11/29/2022]
Abstract
Helicobacter pylori was found to be highly prevalent in asymptomatic HIV-positive and negative patients. The success of H. pylori eradication was limited, especially in HIV-infected patients. There are possible high rates of antibiotic resistance and drug interactions in HIV patients.
Objectives Helicobacter pylori is a widespread pathogen and major contributor to dyspeptic disease and gastric cancer. Although the interaction between HIV and H. pylori infection is not well investigated, previous studies have suggested a decreased prevalence of H. pylori and limited efficacy of eradication therapy in HIV-positive individuals. Therefore, the objectives of this study were to describe the prevalence of H. pylori infection according to HIV status and analyze the efficacy of eradication therapy in Ethiopia. Methods A prospective, randomized, interventional study was performed involving HIV-positive and negative participants presenting to the Asella Referral and Teaching Hospital in Central Ethiopia between March and June 2017. A stool antigen test was used as a screening tool for H. pylori infection. Randomly selected patients received triple eradication therapy. Results The cumulative H. pylori prevalence was 77.3% (392/507): 78.8% (241/306) among HIV-positive individuals versus 75.1% (151/201) among HIV-negative individuals (P = 0.386). Twenty-five HIV-positive and 26 HIV-negative H. pylori-infected participants were randomized to receive standard triple therapy; three of them were lost to follow-up (one HIV-positive, two HIV-negative). The total eradication rate was 50.0%: 62.5% (15/24) among those HIV-negative versus 37.5% (9/24) among those HIV-positive [Au?1]. Conclusions A high prevalence of H. pylori was observed among HIV-positive and negative individuals in Central Ethiopia. The efficacy of eradication therapy was low, with a trend towards lower efficacy in HIV-infected individuals.

Abstract
OBJECTIVE To evaluate the general population's awareness of and attitudes toward Helicobacter pylori (HP) screening and health behaviours. DESIGN Cross-sectional study. SETTING Hengyang, Hunan Province, China. PARTICIPANTS Using stratified cluster random sampling, a pretested structured questionnaire was used to interview members of the general population aged ≥18 years. PRIMARY AND SECONDARY OUTCOME MEASURES Knowledge of and attitudes toward HP screening and associated health behaviours, sociodemographic factors associated with HP knowledge, and screening behaviours. RESULTS This study featured 1042 participants. The average knowledge score was 11 (QL=4, QU=20, range 0-29). Approximately 68.9% of the participants said they had heard of HP, but 67.5% had never had an HP test. The most common reasons for not undergoing screening were 'no symptoms' (55.7%) and 'lack of knowledge regarding the benefits of the test' (21.1%). Independent factors related to knowledge included age, education level, occupation, HP infection, frequency of drinking unboiled water (p<0.05). Factors independently associated with screening behaviour included occupation, average monthly income, presence/absence of indigestion, stomach discomfort or pain, and/or stomach disease and knowledge score (p<0.05). Overall, 941 (90.3%) participants never used anti-HP toothpaste, and 442 (40.5%) never used serving spoons or chopsticks. The risk factors for HP infection included eating out and eating in groups (p<0.05). CONCLUSION In China, the general population has poor knowledge of HP, but most people have a positive attitude towards HP screening. Being asymptomatic and lacking knowledge about testing were the main reasons for reluctance to be screened. These results highlight the urgent need for educational activities to raise awareness, enhance screening rates for HP, and encourage people to adopt a healthy lifestyle.

Abstract
INTRODUCTION Infection with Helicobacter pylori is one of the most frequent chronic bacterial illnesses in humans. Pregnant mothers are the populations most vulnerable to H. pylori infection. The objective of this study was to assess the prevalence of H. pylori infection and associated factors among pregnant mothers having antenatal care at Debre Tabor General Hospital, Debre Tabor, Ethiopia, 2021. METHODS AND MATERIALS Institutional based cross-sectional study design was conducted on 290 pregnant women. The stool antigen test is used to detect the active presence of the H. pylori antigen in the feces. Bivariate and multivariable logistic regression analyses were carried out to assess potential factors responsible for H. pylori infection. Variables associated with the prevalence of H. pylori infection with (p-value < 0.05) were considered statistically significant. RESULTS The prevalence of H. pylori infection was 17.9%, with 95% (CI: 13.4%-22.3%). In all, 65.4% of H. pylori infection positive mothers had gastrointestinal problems and developed symptoms like abdominal cramp and diarrhea 1 (1.92%), loss of appetite 10 (19.23%), hiccups 9 (17.31%), abdominal pain which worsens when the stomach is empty 19 (36.54%), indigestion, and frequent heart burn 13 (25%) during the present pregnancy. Lesser frequency of handwashing practice AOR = 3.09, 95% CI (1.14-8.34), use of soap for handwashing AOR = 0.44, 95% CI (0.19-0.98), eating unwashed vegetables and fruits AOR = 2.279, 95% CI (1.03-5.04), and not being anemic AOR = 0.268, 95% CI (0.10- 0.71), were significantly associated with H. pylori infection. CONCLUSIONS This study shows that the prevalence of H. pylori infection among pregnant women was low compared with that of the general population. Although in the lower prevalence, the level of anemia was strongly associated with the prevalence of H. pylori infection. This implies that H. pylori infection is a public health problem.

Incidence of celiac disease autoimmunity and associations with maternal tuberculosis and pediatric Helicobacter pylori infections in 4-year-old Ethiopian children followed up in an HLA genotyped birth cohort. Front Pediatr 2022; 10:999287. [PMID: 36389354 PMCID: PMC9644195 DOI: 10.3389/fped.2022.999287] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Accepted: 09/28/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND The prevalence of celiac disease in the general population is mainly unknown in most of sub-Saharan African countries. The aim of this study was to determine the incidence of celiac disease autoimmunity (CDA) and its associations with latent Mycobacterium tuberculosis (LMTB) and Helicobacter pylori (HP) infections in Ethiopian children aged 4 years in an HLA genotyped cohort study. METHODS Of 1,389 recruited children between 2018 and 2022, 1,046 (75.3%) had been screened at least twice for celiac disease between the ages of 2 and 4 years using a tissue transglutaminase autoantibody (tTGA) ELISA kit. Tissue TGA-positive children were retested using radio-binding assays. CDA was defined as persistent-confirmed tTGA positivity in two consecutive samples. Associations of CDA with LMTB and HP were tested in a subpopulation of 752 children born to mothers who were previously tested for LMTB with IFN-γ and anti-HP antibodies in samples collected at a mean age of 49.3 ± 5.3 months. RESULTS Screening detected 38 out of 1,046 (3.6%) IgA-tTGA-positive children. Ten (1.0%) were confirmed to be positive, with six (0.6%) children diagnosed with CDA. The incidence of CDA at 4 years of age was 1.2 per 1,000 person-years. LMTB was found in 4 of 6 (66.7%) mothers with CDA children compared with 340 of 734 (46.3%) mothers of children without CDA (p = 0.424), while HP was found in 3 of 6 (50.0%) CDA children compared with 315 of 746 (42.2%) children without CDA (p = 0.702). CONCLUSION The incidence of CDA in Ethiopian children is lower than the pooled global incidence. Neither LMTB nor HP infections are associated with CD in Ethiopian children.

Abstract
Helicobacter pylori (H. pylori) is a well-known pathogen that infects approximately half of the world's population. It is a pathogenic agent with potential health hazards related to diverse diseases, especially digestive diseases, such as chronic gastritis, peptic ulcer, and gastric carcinoma. In clinical, antibiotics are commonly applied in eradication therapy of H. pylori. However, the increase in antibiotic resistance and side effects has induced the failure of eradication therapy. Recent studies have shown that probiotic supplementation has promising application prospects. It can restore the gastrointestinal microbiota balance and prevent dysbacteriosis caused by antibiotics. Furthermore, it has been reported to have direct or indirect inhibitory effects on H. pylori. Probiotics may have a beneficial effect on H. pylori eradication. However, the strain, dosages, duration times, and safety of probiotic supplementation need further study before clinical applications.

Abstract
Objective Familial transmission can possibly influence the infection and treatment of Helicobacter pylori. This study aimed to describe the prevalence of H. pylori infection and outcomes of eradication treatment among Vietnamese patients who live in the same households. Methods We conducted a prospective cohort study of Vietnamese household members with upper gastrointestinal complaints. Participants received esophagogastroduodenoscopy and H. pylori testing. The H. pylori-positive patients were treated and asked to return for follow-up within 4 months. To explore factors associated with H. pylori infection at baseline, we performed multilevel logistic regression to account for the clustering effect of living in the same households. To explore factors associated with eradication failure, we used Poisson regression with robust variance estimation to estimate the risk ratio. Results The prevalence of H. pylori infection was 83.5% and highest among children <12 years old (92.2%) in 1,272 patients from 482 households. There were variations in H. pylori infection across households (intraclass correlation = 0.14, 95% confidence interval (CI) 0.05, 0.33). Children aged <12 years had higher odds of H. pylori infection (odds ratio = 3.41, 95%CI 2.11, 5.50). At follow-up, H. pylori was eradicated in 264 of 341 patients (77.4%). The risk of eradication failure was lower for the sequential regimen with tetracycline. Conclusion H. pylori infection was common among people living in the same households. Eradication success for H. pylori was higher for the tetracycline sequential regimen. More research should be focused on how family factors influence H. pylori infection and on eradication treatment.

Abstract
Microorganisms have been known to coexist in various parts of human body including the gut. The interactions between microbes and the surrounding tissues of the host are critical for fine fettle of the gut. The incidence of such microorganisms tends to vary among specific type of cancer affected individuals. Such microbial communities of specific tumor sites in cancer affected individuals could plausibly be used as prognostic and/or diagnostic markers for tumors associated with that specific site. Microorganisms of intestinal and non-intestinal origins including Helicobacter pylori can target several organs, act as carcinogens and promote cancer. It is interesting to note that diets causing inflammation can also increase the cancer risk. Yet, dietary supplementation with prebiotics and probiotics can reduce the incidence of cancer. Therefore, both diet and microbial community of the gut have dual roles of prevention and oncogenesis. Hence, this review intends to summarize certain important details related to gut microbiome and cancer.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection is a global public health problem, a higher burden of the infection was reported in developing countries including Ethiopia. It has been associated with several gastrointestinal diseases, and recently implicated in some hematological abnormalities. Despite the high prevalence of H. pylori infection in Ethiopia, there was limited data regarding the relationship between hematological parameters with H. pylori infection. Therefore, this study aimed to evaluate selected hematological parameters of H. pylori-infected patients attending Wachemo University Nigist Eleni Mohammed Memorial Referral Hospital (WUNEMMRH), Hosanna, Southern, Ethiopia. METHODS AND MATERIALS A comparative cross-sectional study was conducted from January to May 2019 among 374 (187 H. pylori-infected patients and 187controls) study participants. Data on socio-demographic characteristics were collected using a structured questionnaire. A five-milliliter venous blood sample was collected for hematological parameter analysis. Approximately two gram of stool specimen was collected to assess the presence of H. pylori antigen. Data were entered and analyzed by using SPSS version 21. Pearson correlation analysis and independent sample T-test was performed, and P-value < 0.05 was considered statistically significant. RESULTS Mean value of Hgb (p<0.001), RBC count (p<0.001), HCT (p<0.001), MCV (p=0.003), MCH (p=0.008), and MCHC (p=0.006) of H. pylori-infected patients were significantly lower than control group. However, the mean value of RDW (p=0.003) in H. pylori-infected patients was significantly higher than in the control group. About 13.3%, 7%, 6.4%, and 18.2% of H. pylori-infected patients showed reduced Hgb concentration, RBC count, HCT, and MCV values, respectively. CONCLUSION The study showed a statistically significant difference in the mean value of Hgb, RBC count, HCT, MCV, MCH, MCHC, and RDW of H. pylori-infected patients and controls. Thus, hematological parameters should be considered for proper diagnosis and management of H. pylori-infected patients and eradication of this microorganism from infected patients, determination of hematological parameters for H. pylori-infected patients were recommended.

Abstract
BACKGROUND Symptom resolution is the most common clinical practice during assessment and evaluation of helicobacter pylori infected patients after employing eradication therapy. OBJECTIVE Prediction of eradication of H. pylori with symptom resolution and assess factors affecting symptom resolution. METHOD Facility based follow up study was done on consented H. pylori positive adult patients who received standard triple therapy consisting of a proton pump inhibitor, amoxicillin, and clarithromycin from May 2016 to April 2018 at Bahir Dar city in Ethiopia. Sociodemographic and clinical data was collected before and after eradication therapy by using pre-developed structured questionnaire. Both positive and negative predictive values were calculated. SPSS version 23 was used to conduct bivariate and backward stepwise multivariate logistic regression to analyze data. P-value < 0.05 at 95%CI was considered as significant. RESULT The study involved a total of 421 patients who completed follow up. Patients' mean age and body weight (±SD) were 30.63 (± 10.74) years and 56.71 (± 10.19) kg, respectively. Complete symptom resolution was achieved in 84.3% of the patients and eradication of H. pylori was successful in 90% of patients. Positive predictive value of complete symptom resolution for H. pylori eradication was 98.9% (351/355) and whereas negative predictive value was 57.6%(38/66). Factors associated with complete symptom resolution were regimen completion (AOR: 2.77 95%CI (1.12-6.86), p = 0.028) and no use of traditional homemade supplements prepared from Fenugreek or Flaxseed (AOR: 2.09 95%CI (1.22-3.58), p = 0.007). CONCLUSION Complete symptom resolution is a powerful predictor of success of H. pylori eradication and can be used to assess H. pylori status after eradication therapy. Assessment of complete symptom resolution should consider regimen completion and traditional practice of using homemade supplements prepared from Fenugreek or Flaxseed.

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.

Concurrent infection of intestinal parasites and Helicobacter pylori among school-age children in Central Ethiopia. Parasite Epidemiol Control 2020; 11:e00177. [PMID: 32944660 PMCID: PMC7481810 DOI: 10.1016/j.parepi.2020.e00177] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2020] [Revised: 07/03/2020] [Accepted: 08/16/2020] [Indexed: 12/13/2022] Open
Abstract
Background Coinfection of multiple intestinal microbial pathogens plays an important role in individuals harboring these organisms. However, data on magnitude and risk factors are scarce from resource limited settings. Objective We examined the prevalence and associated risk factors of intestinal parasites and Helicobacter pylori co-infection among young Ethiopian school children. Method Data from a total of 434 Ethiopian school children from the Ziway region were analyzed in the study. Stool antigen and blood serum antibody tests were used to detect H. pylori, while the presence of any intestinal parasites was detected using direct wet mount microscopy and formol-ether concentration techniques. A structured questionnaire was delivered to mothers and legal guardians of the children by an interviewer to collect data relevant demographic and lifestyle factors. Multivariate logistic regression analysis was performed to assess the association of these sociodemographic characteristics with the coinfection of H. pylori and intestinal parasites. Results The prevalence of coinfection with any intestinal parasites and Helicobacter pylori was 23.0% (n = 92/400). Univariate analysis showed an increased risk for co-infection among children whose mothers had non-formal education (COR: 1.917, p < 0.01) and those who had no history of child vaccination (COR: 3.455, p = 0.084). Children aged 10–14 and those who lived in a house that had a flush or ventilated latrine were found at lower odds of coinfection between intestinal parasites and Helicobacter pylori (COR: 0.670, p = 0.382; COR: 0.189, p = 0.108). Multivariate regression analysis showed increased odds of co-infection among children whose mothers had non-formal education (AOR: 1.978, p < 0.01). Maternal education was also associated with a two-fold increase in odds for H. pylori and any protozoa co-infection (AOR: 2.047, p < 0.01). Conclusion Our study shows a moderate prevalence of H. pylori and intestinal parasite co-infection and identified maternal education as a significant risk factor among school children.

Abstract
Background Helicobacter pylori infection is a public health problem associated with chronic gastritis, peptic ulcer, and gastric cancer. It is endemic in developing countries like Ethiopia. This study was aimed to assess seroprevalence of H. pylori infection and associated factors among adults’ dyspeptic patients in public health facilities of Mizan Aman Town, Southwest Ethiopia. Methods Cross-sectional study was conducted in public health facilities of Mizan Aman Town, from April 1, 2018, to June 30, 2018. A total of 208 adult dyspeptic patients were included in the study. A structured questionnaire was used to collect data. Serum was tested for anti-H. pylori antibody using a commercial test strip. Data were entered using Epi info 6.04 and exported to SPSS 21 for analysis. Bivariate and multivariate logistic regression was employed and OR with 95% CI was retrieved. P-value of less than 0.05 was considered as statistically significant. Results A total of 208 participants were interviewed. The mean age of respondents was 31.70 (SD ±9.123) years. Seroprevalence of H. pylori infection was 89 (42.8%). Presence of domestic animals (AOR = 13.33, 95% CI = (2.203–80.692)), sources of drinking water (AOR = 0.011, 95% CI = (0.001–0.110)), toilet type (AOR = 11.236, 95% CI = (1.921–65.73)), shared beds with siblings (AOR = 7.775, 95% CI = (1.676–36.082)), family size (AOR = 0.015, 95% CI = (0.003, 0.089)), storing and reusing water (AOR =0.014, 95% CI = (0.002–0.103)) and occupational status (AOR = 23.33, 95% CI = (2.034–67.661)) were variables significantly associated with seroprevalence of H. pylori. Conclusion Seroprevalence of H. pylori infection is relatively high in Ethiopia. Family size, shared bed, presences of domestic animals, storage and reuse of water, toilet type, sources of drinking water, and occupation were significant factors associated with H. pylori infection. The possible identified modifiable risk factors should be addressed through effective health education.

Abstract
Helicobacter pylori is one of the most prevalent infection worldwide. It affects individuals of different age groups. Elderly people tend to resist eradication treatment and worsening of infection can lead to several gastric and non-gastric pathologies. Aging-associated cellular and molecular alteration can increase the risk of other pathologies such as osteoporosis, Alzheimer's disease, Parkinson's disease, respiratory and renal dysfunction, and cancer in geriatric patients, more than other age groups. This review article highlights some of the most common old age diseases and the role of H. pylori infection as a risk factor to worsen the conditions, presented by the molecular evidences of these associations. These studies can help clinicians to understand the underlying pathogenesis of the disease and identify high-risk patients, aiding clearer diagnosis and treatment.

Abstract
OBJECTIVE Systematic reviews and meta-analyses have revealed the associations between H. pylori infection and various health outcomes. We aimed to evaluate the strength and breadth of evidence on the associations. DESIGN Umbrella review of systematic reviews and meta-analyses. SETTING No settings. PARTICIPANTS No patients involved. DATA SOURCES Embase, PubMed, Web of Science, Cochrane Library Databases, CNKI, VIP database and Wangfang database from inception to February 1, 2019. OUTCOMES MEASURES Diverse diseases (such as cancer and ischaemic heart disease). RESULTS Sixty articles reporting 88 unique outcomes met the eligible criteria. 74 unique outcomes had nominal significance (p<0.05). Of the outcomes with significance, 61 had harmful associations and 13 had beneficial associations. Furthermore, 73% (64) of the outcomes exhibited significant heterogeneity . Of the these meta-analyses, 32 had moderate to high heterogeneity (I2=50%-75%) and 24 had high heterogeneity (I2>75%). Moreover, 20% exhibited publication bias (p<0.1). In addition, 97% of the methodological qualities were rated 'critically low'. 36% of the evidence qualities of outcomes were rated 'low', 56% of the evidence qualities were rated 'very low' and 8% of the evidence qualities were rated 'moderate'. H. pylori infection may be associated with an increased risk of five diseases and a decreased risk of irritable bowel syndrome. CONCLUSION Although 60 meta-analyses explored 88 unique outcomes, moderate quality evidence only existed for six outcomes with statistical significance. H. pylori infection may be associated with a decreased risk of irritable bowel syndrome and an increased risk of hypertriglyceridemia, chronic cholecystitis and cholelithiasis, gestational diabetes mellitus, gastric cancer and systemic sclerosis.

Abstract
This review summarizes recent publications on the epidemiology of Helicobacter pylori. Two major systemic analyses, from Malaysia and Ethiopia, were published. The Brazilian Consensus Conference has stated that H pylori infection is an infectious disease with an indication for antimicrobial therapy. A continuous decrease in H pylori prevalence was reported from many regions worldwide, including Korea, China, Iran, and Austria. A cross-sectional H pylori prevalence study conducted in the United Arab Emirates found 41% prevalence in a group of healthy children and adults. Several studies from Asia addressed H pylori prevalence in adults undergoing regular checkup. The largest of such studies, performed in Korea, involved 24 471 subjects and reported 41.5% seroprevalence. A relatively smaller study from East China on 3252 subjects reported 27.5% prevalence. In contrast, a study from Spain reported 87.2% seroprevalence. A report on the association between smoking and H pylori seropositivity was published on behalf of the Stomach Cancer Pooling (StoP) Project-a consortium of epidemiological studies of gastric cancer. Also, other potential risk factors, including occupational risk factors, water supply, and food were analyzed. Gastroesophageal reflux and sexual partners has been associated with a higher risk for H pylori acquisition, and gut microbiota was suggested to play a role in intrafamilial transmission of H pylori. Finally, in a few studies (from Mexico and Japan), the catalytic model for predicting the potential risk of acquiring H pylori infection in the future was used. As anticipated, a further decline in H pylori-related disease was demonstrated by applying the modeling.

Abstract
Helicobacter pylori (H. pylori) is the causative agent of gastritis, peptic ulcer disease, mucosa associated lymphoid tissue lymphoma and gastric cancer (GC). While this bacterium infects 50% of the world’s population, in Africa its prevalence reach as high as 80% as the infection is acquired during childhood. Risk factors for H. pylori acquisition have been reported to be mainly due to overcrowding, to have infected siblings or parent and to unsafe water sources. Despite this high H. pylori prevalence there still does not exist an African guideline, equivalent to the Maastricht V/Florence Consensus Report of the European Helicobacter and Microbiota Study Group for the management of this infection. In this continent, although there is a paucity of epidemiologic data, a contrast between the high prevalence of H. pylori infection and the low incidence of GC has been reported. This phenomenon is the so-called “African Enigma” and it has been hypothesized that it could be explained by environmental, dietary and genetic factors. A heterogeneity of data both on diagnosis and on therapy have been published. In this context, it is evident that in several African countries the increasing rate of bacterial resistance, mainly to metronidazole and clarithromycin, requires continental guidelines to recommend the appropriate management of H. pylori. The aim of this manuscript is to review current literature on H. pylori infection in Africa, in terms of prevalence, risk factors, impact on human health, treatment and challenges encountered so as to proffer possible solutions to reduce H. pylori transmission in this continent.
