[PMID: 38040991 PMCID: PMC10920553 DOI: 10.1007/s42770-023-01190-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 11/16/2023] [Indexed: 12/03/2023] Open
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.

Kebede T, Ashenafi H. The Burden and Risk Factors of Helicobacter Pylori Infection Among Government Employees Who Clinically Complain of Indigestion but Allergic Diseases in Southeastern Ethiopia: A Multi-Institution Cross-Sectional Study. Res Rep Trop Med 2024; 15:25-49. [PMID: 38406662 PMCID: PMC10885702 DOI: 10.2147/rrtm.s447203] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Accepted: 02/13/2024] [Indexed: 02/27/2024] Open
Abstract
Background Helicobacter pylori (H. pylori) is believed to have spread from East Africa, but its burden is still unknown in less privileged regions of Ethiopia. Indigestion is an upset stomach, upper abdomen discomfort, heartburn, and bloating. This study evaluated the burden and risk factors for H. pylori infection among government employees who clinically complained of indigestion but allergic diseases in five public health institutions in Southeastern Ethiopia. Methods A health facilities-based cross-sectional survey study was conducted in Southeastern Ethiopia from March to November 2022, employing cluster sampling. Blood specimens, clinical data, and semi-structured questionnaires about risk factors were collected. Data analysis was conducted using descriptive, bivariate, and multivariable logistic regression in STATA software, Windows version 16.1. Results The overall prevalence of infection was found to be 77.6%. The sampled health institution (ρ-value < 0.05), engagement in sideline business (ρ-value < 0.05), sharing local spoon on meal [AOR = 39.30; CI:19.52 -78.31; ρ-value < 0.001], admitting "Gursha" during meal [AOR = 71.48; CI:3.99 -1279.77; ρ-value < 0.05], the toilet type [AOR = 1410.98; CI:121.16 -16,431.19; ρ-value < 0.001], alcohol drinking [AOR = 15.15; CI:1.90 -120.62; ρ-value < 0.05], sleeping hours length [AOR = 15.01; CI:13.48-55.96; ρ-value < 0.001], chewing Khat [AOR = 76.73; CI:8.57-687.07; ρ-value < 0.001], and regular hand washing before eating [AOR = 0.15; CI:0.12-0.19; ρ-value < 0.05] were the independent predictors of H. pylori infection. Conclusion The prevalence rate of H. pylori infection in Southeastern Ethiopia is agonizingly high, exceeding the world average by 27.6%, the first report, and seems to be one of the neglected infectious diseases. Hence, the Oromia Region Health Bureau should reinvigorate the basic infectious disease control methods, establish routine laboratory diagnostic platforms, and intervene in selected societal practices spreading infections.

A survey on Helicobacter pylori infection rate in Hainan Province and analysis of related risk factors. BMC Gastroenterol 2023; 23:338. [PMID: 37777740 PMCID: PMC10544117 DOI: 10.1186/s12876-023-02973-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Accepted: 09/26/2023] [Indexed: 10/02/2023] Open
Abstract
OBJECTIVE The aim of this study was to understand the prevalence and potential risk factors of Helicobacter pylori (H. pylori) infection in Hainan Province, China. METHODS We conducted this study in 21 health service stations in 5 cities of Hainan Province from August 2022 to April 2023. We selected the various participants based on a stratified whole-group sampling method. The 14C-UBT was used to analyze H. pylori infection in 3632 participants. We also analyzed the possible relationship between variables and H. pylori infection based on chi-square test and multifactorial logistic regression. The model was evaluated by performing a Hosmer-Lemeshow goodness-of-fit test and plotting receiver operating characteristic(ROC) curves. RESULTS In total, the results of 3632 eligible participants (age: 14 to 93 years) were included in the analysis. The total prevalence of H. pylori infection in Hainan Province was approximately 38.7%. The prevalence of H. pylori infection was found to increase with age, stabilized in the age group of 45 to 64 years, but peaked in the age group of 65 years and older. In multifactorial analysis, the prevalence of H. pylori infection was positively associated with middle-aged adults (45-64 years), older adults (≥ 65 years), drinking, farmers, natural labor, routinely share utensils, have habit of frequent betel nut consumption, upper gastrointestinal symptoms, and family history of gastric cancer. The factors negatively associated with prevalence included family size ≤ 3, washing hands often before meals, frequent exercise, regular meals, and frequent consumption of fruits and vegetables. In addition, the Hosmer-Lemeshow test showed a good fit (χ2 = 12.983, P = 0.112) and the area under ROC was 0.631 (95%CI: 0.613 ~ 0.649). CONCLUSION The prevalence of H. pylori infection in Hainan Province was observed to be moderate and closely related to age, local socioeconomic conditions, hygienic status and dietary habits.

Helicobacter pylori Infection: Current Status and Future Prospects on Diagnostic, Therapeutic and Control Challenges. Antibiotics (Basel) 2023; 12:antibiotics12020191. [PMID: 36830102 PMCID: PMC9952126 DOI: 10.3390/antibiotics12020191] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 12/26/2022] [Accepted: 01/06/2023] [Indexed: 01/20/2023] Open
Abstract
Helicobacter pylori (H. pylori) infection, which affects approximately half of the world's population, remains a serious public health problem. As H. pylori infection leads to a number of gastric pathologies, including inflammation, gastroduodenal ulcers, and malignancies, early detection and treatment are crucial to preventing the spread of the infection. Multiple extragastric complications, such as iron deficiency anaemia, immune thrombocytopenic purpura, vitamin B12 deficiency, diabetes mellitus, cardiovascular diseases, and certain neurological disorders, have also been linked to H. pylori infection. An awareness of H. pylori and associated health hazards is necessary to minimize or even eradicate the infection. Therefore, there is an urgent need to raise the standards for the currently employed diagnostic, eradication, alternative treatment strategies. In addition, a brief overview of traditional and cutting-edge approaches that have proven effective in identifying and managing H. pylori is needed. Based on the test and laboratory equipment available and patient clinical characteristics, the optimal diagnostic approach requires weighing several factors. The pathophysiology and pathogenic mechanisms of H. pylori should also be studied, focusing more on the infection-causing virulence factors of this bacterium. Accordingly, this review aims to demonstrate the various diagnostic, pathophysiological, therapeutic, and eradication tactics available for H. pylori, emphasizing both their advantages and disadvantages. Invasive methods (such as quick urease testing, biopsy, or culture) or noninvasive methods (such as breath tests, stool investigations, or serological tests) can be used. We also present the most recent worldwide recommendations along with scientific evidence for treating H. pylori. In addition to the current antibiotic regimens, alternative therapies may also be considered. It is imperative to eradicate the infections caused by H. pylori as soon as possible to prevent problems and the development of stomach cancer. In conclusion, significant advances have been made in identifying and treating H. pylori. To improve eradication rates, peptide mass fingerprinting can be used as a diagnostic tool, and vaccines can also eliminate the infection.

Abstract
INTRODUCTION Helicobacter pylori is one of the most common bacterial infections of humankind that affects more than 50% of the world's population. It has been implicated as an important agent in the pathogenesis of peptic ulcer disease and gastric cancer. Data regarding its prevalence using stool antigen test is scarce in Ethiopia. Hence, the main aim of this study is to determine the prevalence of Helicobacter pylori infection among dyspeptic patients using stool antigen test and assessing the potential risk factors. METHODS Institution based cross-sectional study was conducted on 373 dyspepsia patients. Data were collected using a pre-tested interviewer administered questionnaire. SPSS Version 23 for Windows software was used for summarization and analyses of data. Bivariate analysis was conducted to detect the association between dependent and independent variables, and all candidate variables were entered into multivariate logistic regression. Statistical significance was set at p-value <0.05. RESULT More than one-third (34%) of dyspepsia patients were positive for H. pylori stool antigen test. Having greater than or equal to four children in the house [AOR = 7.5 95% CI (1.7, 33.6) p = 0.008)], absence of latrine for the house hold [AOR = 4.3 95% CI (1, 17.8), p = 0.043 and drinking of river water [AOR = 12.5 95% CI (1.5, 105), p = 0.021] were predictors of H-pylori infection. CONCLUSION More than one-third of dyspepsia patients were positive for H-pylori infection. Overcrowding and poor hygienic conditions are the main risk factors of H-pylori infection.

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.

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: Despite all improvements in sanitation and exposure to antibiotics over time, Helicobacter pylori (HP) prevalence remains high, affecting the lives of about half of the world population, which can gradually lead to serious upper gastrointestinal disorders. Understanding HP's epidemiologic patterns help us to better manage the burden of this infection and to plan more effectively regarding potential screening or eradication strategies. We, therefore, aimed to report the crude and age- and sex-standardized prevalence rate of HP infection, its trend, and possible associated factors among asymptomatic healthy individuals in Rafsanjan city, a low-incidence area of gastric cancer (GC) in the southeast of Iran, from July 2018 to December 2021. Methods: This population-based cross-sectional descriptive study included 2,046 male and female subjects between 3 to 72 years who were in good health condition. Study participants were randomly selected from the Health Houses and each underwent a questionnaire-based interview and provided blood and feces samples. The presence of HP infection was detected by serum IgG antibodies and stool antigen test. Results: The overall and age- and sex-standardized prevalence rates of HP infection were 50.9% and 43%, respectively. The prevalence rate has notably decreased in all age groups compared with 2007. Also, it was significantly higher among men (P=0.033) and increased with advancing age (P<0.001). A higher population density living in a specific room area (P=0.012) increased the likelihood of HP infection. Conclusion: To conclude, the prevalence of HP infection is decreasing over time in Rafsanjan city, which may be due to improvements in living standards in this area. A healthy lifestyle and adherence to hygienic principles, especially during childhood, may be required for a reduction in the prevalence of HP infection.

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.

Helicobacter pylori Infection: Comparison of Knowledge between Health Science and Non-Health Science University Students. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18158173. [PMID: 34360466 PMCID: PMC8346000 DOI: 10.3390/ijerph18158173] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Revised: 07/25/2021] [Accepted: 07/28/2021] [Indexed: 12/24/2022]
Abstract
Background: Helicobacter pylori (H. pylori), an important human pathogen, is classified as a human carcinogen. It is known to cause dyspepsia, peptic ulcers, and gastric cancer. Awareness regarding H. pylori infections in Saudi Arabia awaits investigation to reduce or even eliminate the infection that would ease the substantial burden of managing H. pylori among both malignant and non-malignant diseases. Aims: The study aims were to (1) assess the knowledge of H. pylori infection, testing, and management among undergraduate students in Saudi Arabia and (2) compare the H. pylori knowledge among health science and non-health science students. Methods: This study involved a cross-sectional online survey among 334 undergraduate students in health science and non-health science colleges at King Saud University, Saudi Arabia, using a valid and reliable author-developed survey. The survey had two sections: the socio-demographic factors and knowledge items regarding H. pylori. Data were collected during the 2019–2020 academic year. Data analysis included descriptive statistics, Chi-square, and Mann–Whitney U test. The knowledge scores were categorized as poor, fair, and good. Results: Less than 10% of the students in both groups had a good knowledge level about H. pylori. The comparison of the overall mean between both groups was non-significant. Moreover, the level of knowledge of the respondents was significantly associated with their university level (p < 0.001), family monthly income (p < 0.007), having heard about H. pylori infection (p < 000.1), and a previous history of H. pylori infection (p < 000.1). Conclusion: The overall knowledge level of Saudi undergraduate students about H. pylori infection was low. Thus, health awareness interventions through educational programs are recommended for improving their knowledge about H. pylori infection and its prevention.

Identification of antibiotic resistance patterns in Helicobacter pylori strains isolated from gastric biopsies using real-time PCR and genotypic analysis. Ann Gastroenterol 2021; 34:501-509. [PMID: 34276188 PMCID: PMC8276370 DOI: 10.20524/aog.2021.0624] [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: 07/16/2020] [Accepted: 02/01/2021] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Helicobacter pylori (H. pylori) is associated with dyspepsia, mucus-associated lymphoid tissue lymphoma, gastritis, and peptic ulcer disease. Treatment in Malta consists of triple therapy, which consists of a proton pump inhibitor and 2 of the antibiotics amoxicillin, clarithromycin, metronidazole and fluoroquinolones. We aimed to determine the resistance rates for clarithromycin and fluoroquinolones in patients with H. pylori, and its incidence, in patients undergoing an esophagogastroduodenoscopy (EGD) using real-time polymerase chain reaction (RT-PCR). METHODS Patients undergoing an EGD were recruited. A rapid urease test (RUT) was performed, and 4 gastric biopsies were also taken (2 from antrum, 2 from corpus) and analyzed using RT-PCR. Positive samples were tested for antibiotic resistance using amplification and reverse hybridization techniques. RESULTS Two hundred patients (mean age 53.6 [range 20-92] years; 53.1% female) were recruited; the majority were (78%) non-smokers. H. pylori was identified in 21.0% of the patients. Fluoroquinolone resistance was detected in 21.4% of the patients. Clarithromycin resistance was observed in 26.2%, with dual resistance identified in 4.8% of the patients. A high concordance was present with patients testing negative for H. pylori with both RUT and RT-PCR (94.3%). Only 57.6% of patients tested positive with both tests. However, 92.9% of RT-PCR positive patients had a positive genotype HelicoDR test. CONCLUSIONS This data demonstrates a high rate of H. pylori resistance to both clarithromycin and fluoroquinolones. These should be avoided when treating H. pylori by utilizing different treatment regimes. Furthermore, we derived important data on the role of RT-PCR, which may be implemented in routine clinical practice.

Abstract
BACKGROUND Anemia is a worldwide public health problem and also associated with Helicobacter pylori (H. pylori) infection. Determining the association of anemia with H. pylori infection is important to develop evidence-based decision and intervention strategies, which is not well known in Ethiopia. Thus, this study aimed to determine the association between anemia and H. pylori infection among adult dyspeptic patients attending Wachemo University Nigist Eleni Mohammad Memorial Referral Hospital in Southwest Ethiopia. METHODS A cross-sectional study was conducted from January to April 2019 involving 362 consecutive adult dyspeptic patients who came to the hospital during the study period. Socio-demographic, clinical and other related data were collected by structured questionnaires. Four milliliters of the venous blood sample was collected for hematological parameters analysis and blood film preparation. A stool sample was collected to detect H. pylori antigen and intestinal parasites. Data were analyzed by SPSS version 21. Logistic regression analyses were performed and p-value <0.05 was considered as statistically significant. RESULTS The overall prevalence of anemia among dyspeptic patients was 24.3% (95%CI: 19.9-28.7). Among H.pylori infected participants 29.2% were anemic, of which 69.2% had mild anemia and 63.5% had normocytic normochromic anemia. Rural residence (AOR: 1.9, 95%CI: 1.1-3.3), H. pylori infection (AOR: 1.77, 95%CI: 1.05-2.98) and intestinal parasitic infection (AOR: 2.14, 95%CI: 1.14-4.03) were significantly associated with anemia. CONCLUSION The prevalence of anemia in this study indicated that it is a moderate public health problem. Rural residence, H. pylori and intestinal parasitic infection were significantly associated with anemia. The findings of this study should be taken into account for the prevention and control of anemia among dyspeptic adults.

Wu Y, Su T, Zhou X, Lu N, Li Z, Du Y. Awareness and attitudes regarding Helicobacter pylori infection in Chinese physicians and public population: A national cross-sectional survey. Helicobacter 2020; 25:e12705. [PMID: 32476197 DOI: 10.1111/hel.12705] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2020] [Revised: 05/03/2020] [Accepted: 05/06/2020] [Indexed: 12/29/2022]
Abstract
BACKGROUND There is a lack of reports on the awareness of Helicobacter pylori (H pylori) prevention and treatment in the general Chinese population. And whether the knowledge level will affect their action toward screening was unknown. This study aimed to conduct a national survey on the knowledge, attitudes, and practice regarding H pylori infection in Chinese physicians and the public. METHODS This was an Internet-based survey of the general Chinese population and Chinese physicians from different specialties, carried out from January to February 2019. Both surveys (general population's and physicians') included questions to assess the knowledge and attitudes toward H pylori and its action. RESULTS A total of 3211 people and 546 physicians were enrolled. In the population, the proportion of subjects who answered correctly to all questions about H pylori's infectivity was only 16%, and that for H pylori's harmfulness and that for H pylori preventive measures were 35% and 43.6%, respectively. In general, physicians had a better understanding of H pylori's harmfulness (83.9%) than the other population. The vast majority of the surveyed population (87.0%) and physicians (82.2%) supported a national H pylori screening plan to prevent gastric cancer. The support ratio paralleled with the overall knowledge level. Unexpectedly, gastroenterologists tend to have a relatively low support rate for H pylori screening than non-gastroenterologists (58.2% vs 84.2%, P < .001), which may be related to consideration of heavy medical burden (67.3%). CONCLUSIONS The general population in China has relatively insufficient awareness of H pylori, which is incompatible with the highly infectious status. More works on health education are needed to improve the knowledge of this gastric pathogen.

Abstract
Background Investigating distinct individual- and household-level risk factors for acquiring Helicobacter pylori (H. pylori) infection can inform disease prevention efforts and implicate possible routes of transmission. This study determined the magnitude of H. pylori infection among schoolchildren in Ziway, central Ethiopia and identified personal and household correlates of H. pylori infection in young Ethiopian children. Methods A total of 434 schoolchildren participated in this cross-sectional study. Infection status was assessed using antigen and antibody rapid tests. Demographic and lifestyle information was obtained from parents via an interviewer-led questionnaire. Univariate and multivariate logistic regressions were performed to assess the relationships between potential individual- and household-level risk factors and H. pylori infection. Results The prevalence of H. pylori infection was 65.7% (285/434). Of the personal variables assessed, the age group 10–14 years was found to be significantly associated with higher odds of H. pylori infection in univariate analysis (COR = 2.22, 95% CI: 1.06–4.66, p = 0.03) and remained positively correlated after adjusting for confounding factors. Of the household-level factors explored, having a traditional pit or no toilet was found to be significantly associated with 3.93-fold higher odds of H. pylori infection (AOR = 3.93, 95% CI: 1.51–10.3, p = 0.01), while the presence of smokers in the household was associated with 68% lower odds of infection (AOR = 0.32, 95% CI: 0.11–0.89, p = 0.03). Conclusion This study from a developing country provides additional evidence for older age as a personal risk factor for H. pylori infection and identifies correlations between socioeconomic and sanitation household factors and positive childhood infection status. The associations reported here support the hypothesized fecal-oralroute of transmission for H. pylori.

Abstract
The study aims to understand the influence of environmental and lifestyle factors and more specifically the role of tobacco smoke-infused water (tuibur) on Helicobacter pylori infection. It was a cross-sectional study to measure the epidemiological risk factors associated with H. pylori infection among the tribal population in Northeast India. Endoscopic samples were collected from the antrum region of the stomach from 863 participants with gastritis. H. pylori infection was confirmed in 475 samples by the rapid urease test and PCR-based methods. Information on demographic and lifestyle factors was collected using a validated and standardized questionnaire. Logistic regression was used to estimate odds ratio (OR) and 95% confidence interval (CI) for the association between the various factors and H. pylori. The use of tuibur was associated with an increased OR of H. pylori infection (OR = 3.32, 95% Cl = 1.95-5.83). Tobacco chewers (OR = 1.49, 95% Cl = 1.06-2.09), smokers (OR = 1.81, 95% Cl = 1.26-2.61), and alcohol consumers (OR = 1.81, 95% Cl = 1.19-2.76) were also infected with H. pylori. The results were not attenuated after adjusting for major well-known risk factors of H. pylori infection. The habit of tuibur consumption may be a contributing factor to the high prevalence of H. pylori infection and in turn, may contribute to the high prevalence of gastritis among the Mizo population.

Abstract
Background: H. pylori is a class I carcinogen and major cause of gastric cancer. Few previous studies reported
relationship between H. pylori infection, CYP2C19 genotype and functional dyspepsia (FD) subtype. The aim of this
study was to determine relationship between CYP2C19 genotype and FD subtype patients(host factor) with antibiotic
resistant strains of H. pylori infection and CagA genotype(bacterial factor). Methods: FD patients who were investigated
with gastroscopy at Thammasat University Hospital, Thailand during March 2017-November 2017 were enrolled. Two
antral gastric biopsies were obtained for rapid urease test, E-test and cultures. CagA genotypes (CagA1a and CagA2a)
were determined by PCR and CYP2C19 genotype was determined by PCR-RFLP. FD patients were categorized as
epigastric pain syndrome(EPS) and postprandial distress syndrome (PDS). Results: 93 FD patients with H. pylori
infection were enrolled (37 male, 56 female, mean age 54.5 years). There were 33 patients with EPS and 60 patients
with PDS. CYP2C19 genotype revealed 55.9% rapid metabolizer (RM), 40.9% intermediate metabolizer (IM) and
3.2% poor metabolizer (PM) genotypes. Antibiotics susceptibility tests demonstrated 62.8% resistant to metronidazole,
12.9% resistant to clarithromycin and 27.1% resistant to fluoroquinolone. CagA 1a and CagA 2a were demonstrated
in 6 patients(11.5%) and 46 patients(88.5%). CagA2a genotype was more prevalent in PDS than EPS patients
(94.3%vs.76.5%; P =0.08) without significance. In intermediate metabolizer (IM), CagA2a genotype was significant
higher in PDS than EPS(100% vs.25%; P=0.004). Conclusions: PDS, CYP2C19 RM genotype and CagA 2a gene of
H. pylori infection were the predominant type of FD in Thailand. Metronidazole remain the most common antibiotic
resistant strain of H. pylori infection in FD patients. PDS (host factor) was significantly related to CagA2a genotype
(bacterial factors) only in patients with intermediate metabolizer. Appropriate dose of proton pump inhibitor (PPI) and
correct regimens for H. pylori eradication in FD patients should be consider to improve clinical outcomes.

Abstract
Background Helicobacter pylori infection affects more than half of the world's population. The infection is generally acquired during childhood but can remain asymptomatic, with long-term clinical sequelae including gastritis, peptic ulcer disease, and stomach cancer. Methods The study was approved by Institutional Review Committee of Mbarara University of Science and Technology. After obtaining informed consent from parents/legal guardians, illegible children who presented with gastrointestinal complaints at Holy Innocents Children's Hospital were recruited; structured questionnaires were administered to the parents/guardians to collect information on sociodemographic data and risk factors of H. pylori infection. Four (4) millilitres of blood was collected from each child and tested for H. pylori blood Antibody test and stool specimens were used for H. pylori antigen test. Results The prevalence of H. pylori infection among the study participants was 24.3%. The infection rate increased with increase in age of the participants, from 16.2% among 1to 5 years old to 27.2% among 6 to 10 years. Infections were higher among school going children (68/74, p=0.003, OR 3.9; CI: 1.5 to 10.6) and children from crowded households (59/74, p<0.001, OR 2.6, and CI 1.3 to 5.0), unsafe source of drinking water at schools (46/74, p=0.003), and lack of sanitary facility at homes (57/74, p=0.001, and OR 1.6 CI 0.7 to 3.6). Conclusion The prevalence of H. pylori infection among children aged 1 to 15 years at Holy Innocents Children's Hospital was high and increases with age. School attendance, lack of sanitary facility, lack of safe drinking water, and overcrowding were the risk factors associated with H. pylori infection.

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.

[PMID: 30630433 PMCID: PMC6327617 DOI: 10.1186/s12876-018-0927-3] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2018] [Accepted: 12/26/2018] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Helicobacter pylori (H.pylori) infections are prevalent and recognized as major cause of gastrointestinal diseases in Ethiopia. However, Studies conducted on the prevalence, risk factors and other clinical forms of H.pylori on different population and geographical areas are reporting conflicting results. Therefore, this review was conducted to estimate the pooled prevalence of H.pylori infections and associated factors in Ethiopia. METHODS PubMed, Embase, Google scholar, and Ethiopian Universities' repositories were searched following the Preferred Items for Systematic review and Meta-analysis (PRISMA) guideline. The quality of included studies was assessed using the Newcastle-Ottawa Scale in meta-analysis. Heterogeneity between studies was assessed using Cochrane Q test and I2 test statistics based on the random effects model. Comprehensive meta-analysis (CMA 2.0) and Review Manager (RevMan 5.3) were employed to compute the pooled prevalence and summary odds ratios of factors associated with of H.pylori infection. RESULTS Thirty seven studies with a total of 18,890 participants were eligible and included in the analysis. The overall pooled prevalence of H.pylori infection was 52.2% (95% CI: 45.8-58.6). In the subgroup analysis by region, the highest prevalence was found in Somalia (71%; 95% CI: 32.5-92.6) and the lowest prevalence was reported in Oromia (39.9%; 95% CI: 17.3-67.7). Absence of hand washing after toilet (OR = 1.8, 95% CI; 1.19-2.72), alcohol consumption (OR = 1.34, 95% CI; 1.03-1.74) and gastrointestinal (GI) symptoms (OR = 2.23, 95% CI; 1.59-3.14) were associated with H.pylori infection. The trend of H.pylori infection showed a decreasing pattern overtime from 1990 to 2017 in the meta-regression analysis. CONCLUSION The prevalence of H.pylori infection remains high; more than half of Ethiopians were infected. Although the trend of infection showed a decreasing pattern; appropriate use of eradication therapy, health education primarily to improve knowledge and awareness on the transmission dynamics of the bacteria, behavioral changes, adequate sanitation, population screening and diagnosis using multiple tests are required to reduce H.pylori infections. Recognizing the bacteria as a priority issue and designing gastric cancer screening policies are also recommended.

Helicobacter pylori infection among patients presenting with dyspepsia at a primary care setting in Cameroon: seroprevalence, five-year trend and predictors. BMC Infect Dis 2019; 19:30. [PMID: 30621610 PMCID: PMC6325826 DOI: 10.1186/s12879-019-3677-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2018] [Accepted: 01/02/2019] [Indexed: 01/19/2023] Open
Abstract
Background Almost half the world’s population is infected with Helicobacter pylori (H. pylori) with the highest reported prevalence from Africa. This infection is associated with several morbid gastrointestinal conditions. Understanding the trends in seroprevalence and the factors associated with H. pylori seropositivity in dyspeptic persons can provide a guide for public health policies. Methods This was a retrospective study, carried out with outpatient records of Wum District Hospital (WDH) from January 2012 to December 2016. We reviewed records of all patients for whom a H. pylori serology test was requested. The Cochran-Armitage trend test and multiple regression models were used to explore seroprevalence trends and predictors of seropositivity respectively. Results We included 451 records, 63.6% (n = 287) were female. The mean age of the study population was 40.7 years, and the overall H. pylori seroprevalence was 51.5% (95% CI: 47–56%). The use of recommended eradication regimen appears to be low and declining. On average, H. pylori seroprevalence declined by 6.8% annually (p < 0.0001). Occupational status independently predicted seropositivity, with students having lower odds of being seropositive than employed persons (aOR = 0.09, 95% CI: 0.02–0.49, p = 0.016). Conclusion Despite decreasing trends, the seroprevalence of Helicobacter pylori infection is high in dyspeptic patients attending this primary care setting. Improving living standards and establishing national guidelines for eradication can possibly aid the control of this infection.

Abstract
Background: The aim of the study was to assess clinical and socio-demographic characteristics as well as prior drug usage as risk factors for Helicobacter pylori (H. pylori) infection in Nigeria. Methods: A total of 347 respondents were surveyed by assessing their clinical and socio-demographic characteristics in comparison with the non-invasive gold standard for H. pylori diagnosis, the urea breath test (UBT). Chi-square test and odds ratio analyses were conducted in order to assess if variables such as socio-demographic factors, drug intake, and history of ulcer/gastritis/ gastric cancer within the family significantly predicted test results. Results: A total of 130 (37.5%) respondents were positive for H. pylori by the UBT. Living with more than three people in an apartment and a history of ulcer/gastritis within the family were significantly associated with H. pylori (p ≤0.05), as well as current antibiotic intake (p ≤0.05). Nationality, stay outside Nigeria, level of education, main occupation, smoking and drinking habits, sources of drinking water, number of children and history of gastric cancer had no significant association with H. pylori infection (p ≥ 0.05). Conclusion: The results of the questionnaire revealed that most socio-demographic characteristics of the respondents had no significant association with H. pylori. Overcrowding, having siblings/parents with history of ulcer/gastritis as well as prior antibiotic usage had a significant association.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection is the most common chronic bacterial infection in the world. It can result in various upper gastroduodenal diseases. The prevalence varies among countries, population groups within the same country and testing methods. The aim of the study was to determine feco-prevalence and risk factors of H.pylori infection among symptomatic patients in Amhara region, Northeast Ethiopia. METHODS A cross sectional study was conducted in a total of 342 new consecutive outpatients with upper abdominal complaints at Dessie Referral Hospital from May to July, 2016. A structured questionnaire was used to collect the socio-demographic, lifestyle and environmental data. Stool samples were used to detect H. pylori specific antigen. Blood samples were assessed for anti-H. pylori IgG and ABO blood types. SPSS version 20.0 statistical software package was used for data analysis. Chi-square test and logistic regression were used in the analysis and P-value ≤0.05 was considered as statistically significant. RESULTS H. pylori stool antigen and serum anti-H.pylori IgG detection rate was 30.4 and 60.5% respectively with kappa measure of agreement of 0.271. Antigen detection was significantly associated with family size (> 3) [AOR = 1.83, 95% CI: 1.10-3.05, p = 0.02], more persons (> 3) sharing the same bed room in the household [AOR = 2.91, 95% CI: 1.39-6.11, p = 0.005], alcohol consumption (> once a week) [AOR = 2.70, 95% CI: 1.49-4.89, p = 0.001] and individuals' blood type: group O [AOR = 8.93, 95%CI: 1.79-44.48, p = 0.008] and group A [AOR = 5.53, 95%CI: 1.08-28.36, p = 0.040]. Gender, age, marital status, occupation, educational level, residence, smoking as well as coffee, tea, fruits and vegetables consumption were not statistically associated with H. pylori antigen detection (p > 0.05). CONCLUSION The overall H. pylori stool antigen and anti-H. pylori IgG detection rate was 30.4 and 60.5%, respectively. The test agreement was not strongly convincing and needs further evaluation. Alcohol consumption, overcrowding and ABO blood group were significantly associated with H. pylori antigen detection.

Abstract
Background: The association between Helicobacter pylori infection and cardiovascular risk factors remains controversial. The high prevalence of H. pylori infection among Afghan patients warranted the investigation of this association. The aim of the present study was to determine the association between H. pylori infection and cardiovascular risk factors among patients visiting an outpatient clinic in Andkhoy, Afghanistan. Methods: We performed a cross-sectional study of 271 consecutive patients in an outpatient clinic in Andkhoy, Afghanistan from April 2017 to June 2017. The diagnosis of H. pylori infection was achieved using an enzyme-linked immunosorbent assay test. The patients were divided into H. pylori positive (n=189) and H. pylori negative (n=82) groups. The association between H. pylori infection and cardiovascular risk factors was analyzed. Results: Of the total 271 study participants, 102 (37.6%) were male and 169 (62.4%) female. The mean age ± standard deviation of the patients who were H. pylori-positive and H. pylori-negative was 51.0 ± 17.6 years and 51.6 ± 17.6 years, respectively. In multivariate logistic regression analyses, H. pylori infection was significantly associated with diabetes mellitus (DM) (odds ratio [OR] 3.16, 95% confidence interval [CI] 1.31-7.62, P = 0.011), and body mass index (BMI) levels (OR 1.17, 95% CI 108-1.26, P < 0.001). Conclusions: Our study indicated that H. pylori infection was significantly associated with DM and elevated BMI levels in patients from an outpatient clinic in Andkhoy, Afghanistan. More aggressive measures, including DM, obesity control, and H. pylori eradication are needed.

Abstract
OBJECTIVE Intestinal parasites and H. pylori are well-known for their high prevalence worldwide. Thus, the objective of this study waste assess risk factors and co-infection of intestinal parasites and H. pylori among adult patients with upper gastrointestinal complaints. A hospital-based cross sectional study was conducted among 363 consecutive adult patients from December 10, 2015 to February 30,2016. Stool and venous blood were collected for analysis of Intestinal parasites and H. pylori infection, respectively. Data was analyzed using SPSS version 16 and logistic regression analysis was carried out to assess predictors of co-infection. A p ≤ 0.05 was considered as statistically significant. RESULTS Helicobacter pylori IgG and intestinal parasites were detected in 70.25-38.3% of participants, respectively while G. lamblia accounted 22.3%. G. lamblia prevalence was significantly higher among H. pylori infected participants (COR: 2.76; 95% CI: 1.46-5.23), but E. hystolytica/dispar infection didn't show significant variation (p = 0.15). H. pylori and intestinal parasites concomitant co-infection was associated with male sex (AOR: 1.61; 95% CI: 1.01-2.56), consumption of river water (AOR: 1.85; 95% CI: 1.11-3.07) and ground/spring water (AOR: 4.10; 95% CI: 1.97-8.52). Thus, besides H. pylori investigation, upper gastrointestinal symptomatic patients should be screened for G. lamblia infection and other intestinal parasites.

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 prevalence of Helicobacter pylori (H. pylori) infection is reported to be more than 50% worldwide.
It has been associated with peptic ulcer disease, gastric carcinoma, and mucosal-associated lymphoid tissue lymphoma.
The seroprevalence of H. pylori varies greatly among societies and geographical locations. The objective of this
study was to determine the seroprevalence and factors associated with H. pylori infection among dyspeptic patients
in Afghanistan. Materials and Methods: This cross-sectional study was designed to determine the seroprevalence of
H. pylori among dyspeptic patients in an outpatient clinic in Andkhoy, Afghanistan from January 2017 to April 2017.
Data were obtained from patients using a questionnaire, including socio-demographic data and history of smoking
and dyspeptic symptoms. Serum samples were also collected from the patients and tested for H. pylori antibodies
using the enzyme-linked immunosorbent assay. Results: A total of 152 patients with dyspepsia were included in the
analysis; 59 were men (40.0%), and 93 were women (60.0%). The overall seroprevalence of H. pylori was 75.6%. The
predictor of seroprevalence of H. pylori was found to be illiteracy (odds ratio [OR] 4.99, 95% confidence interval [CI]
1.03¬24.17), epigastric pain (OR 12.01, 95% CI 3.56- 40.52), and rural population (OR 9.66, 95% CI 3.36- 27.82).
There was an inverse association between employed status and seroprevalence of H. pylori (OR 0.08, 95% CI 0.01-
0.52). Conclusions: The seroprevalence of H. pylori was high among patient with dyspepsia in an outpatient clinic
in Afghanistan. Illiteracy, unemployment and rural populations, and epigastric pain were significantly associated with
H. pylori infection.

Abstract
Background: Helicobacter pylori (H. pylori) is important cause of peptic ulcer and gastric cancer. Moxifloxacin is
effective antibiotic for treatment for H. pylori. However, there were limited studies as first line therapy. Probiotics had been
shown to decrease therapy-related side-effect and increase eradication rate. Aim of this study was to evaluate the efficacy
of moxifloxacin-dexlansoprazole based triple therapy with probiotic for H. pylori treatment in Thailand. Methods:
Patients with H. pylori infected gastritis were randomized to receive 7- or 14-day moxifloxacin-dexlansoprazole based
triple therapy with probiotic or placebo. Regimen consisted of 60 mg dexlansoprazole twice daily, 400mg moxifloxacin
once daily, 1g clarithromycin MR once daily. Probiotic used in this study was 282.5mg Saccharomyces boulardii (S.
boulardii) in capsule prescribed twice daily. CYP2C19 genotyping, antibiotic susceptibility tests, and CagA genotyping
were also done. Successful eradication was defined as a negative 13C-urea breath test at least 4 weeks after treatment.
Results: Total of 108 subjects was enrolled (27 each to 7-and 14-day regimens with probiotic or placebo). Antibiotic
susceptibility tests showed 29% fluoroquinolone, 19% metronidazole and 4% clarithromycin resistance. CYP2C19
genotyping demonstrated 43%, 47% and 11% were rapid, intermediate and poor metabolizers, respectively. CagA
genes were positive in all patients. Eradication rates of 7-day and 14-day regimens with probiotic were 100%, and
93% respectively. There were no significant differences between eradication rate of 7-day and 14-day regimen with or
without probiotics. Regarding side-effects, incidence of nausea, abdominal discomfort, bitter taste, and diarrhea were
significantly lower in regimen with probiotic group compared with placebo(7.4%vs. 22.2%; p=0.028, 0.00%vs.14.8%;
p=0.003, 35.2%vs.70.4%; p=0.0002, and 0.00%vs.9.3%; p=0.028, respectively). Conclusions: 7-day moxifloxacindexlansoprazole
therapy plus S. boulardii provide an reliable cure rate of H. pylori in non-ulcer dyspeptic patients
in Thailand, independent of CYP2C19 genotype. Probiotic adding also decreased side effects during the treatment.

Abstract
BACKGROUND Helicobacter pylori infection is associated with the development of chronic gastritis, peptic ulcer disease, and gastric cancer. Current clinical recommendations are that H. pylori test-and-treat should be individualized based on comorbidities and patient preferences among populations at increased risk for certain morbidities. However, knowledge, attitudes and practices regarding H. pylori among potential patient populations are largely unknown. MATERIALS We conducted a literature review to assess knowledge, attitudes, and practices of patients or community populations around H. pylori transmission, prevention, and associated morbidity. RESULTS Nine studies met the inclusion criteria, all published between 1997 and 2014. Eight studies evaluated perception of H. pylori among at-risk populations, while one study evaluated perception among a general population. The studies suggest inconsistencies between the perceptions of these populations and the established understanding of knowledge, attitude, and preventive practices for H. pylori among even at-risk populations. CONCLUSION To adequately respond to current test-and-treat recommendations for treatment of H. pylori, general population education must be implemented, especially among at-risk populations. Further work is needed within at-risk populations in the United States to determine prevalence of H. pylori and their current knowledge if adequate prevention strategies are to be designed.

Abstract
Background: The prevalence of Helicobacter pylori (H. pylori) infection in Indonesia has been reported to be
exceedingly low. The purpose of our study was to confirm whether this is the case in Northern Jakarta using a sensitive
13C-urea breath test (UBT), and to examine any associations with lifestyle/environment factors and potential routes
of transmission. Methods: We recruited a total of 196 subjects from a low-income community in Northern Jakarta,
Indonesia, data from 193 who completed a questionnaire about their lifestyle/environment and had UBT being included
as the final. Odds ratios (ORs) adjusted for sex and age with 95% confidence intervals (CIs) were calculated using a
logistic regression model. Results: The overall H. pylori infection rate was 15.0% (95%CI, 10.3-20.9), with variation
among Javanese (9.1%, total=77), Buginese (40.0%, 35), Betawi (9.1%, 33), Sundanese (3.7%, 27), and Batak (40.0%,
5). On multivariate analysis, the ORs for intake of soybean milk, cucumber more than once a week, infrequent hand
washing practice before meals, and alcohol consumption were 0.10 (95%CI: 0.01-0.97), 6.61 (95%CI: 1.87-23.3), 4.10
(95%CI: 1.15-14.6), and 61.9 (95%CI: 1.67-2300.8), respectively. Rates for Buginese (OR=7.84; 95%CI: 1.82-33.8)
and Batak (OR=20.1; 95%CI: 1.90-213.2) were significantly higher than for Javanese. Conclusions: The H. pylori
infection rate in this study was relatively low, in line with previous studies. Regarding ethnicity factors, Buginese and
Batak reported eating food using fingers more frequently than Javanese, Betawi, and Sundanese. Our study indicated
that person-person transmission is possible in this low prevalence area. The low infection rates for H. pylori among
Javanese, Betawi, and Sundanese ethnics could be partly due to their sanitary practices.

Abstract
During the period reviewed, prevalence studies were essentially performed in less economically advanced countries and a high prevalence was found. The traditional risk factors for Helicobacter pylori positivity were mostly found. Transmission studied by molecular typing showed a familial transmission. The eventual role of water transmission was explored in several studies with controversial results. Concerning diagnosis, most of the invasive and noninvasive methods used for the diagnosis of H. pylori infection are long standing with efficient performance. The most interesting recent improvements in H. pylori diagnosis include advances in endoscopy, developments in molecular methods, and the introduction of omics-based techniques. Interpretation of old or newer method should take into account the pretest probability and the prevalence of H. pylori in the population under investigation.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) remains an important cause of gastric cancer and peptic ulcer disease worldwide. Treatment of H. pylori infection is one of the effective ways to prevent gastric cancer. However, standard triple therapy for H. pylori eradication is no longer effective in many countries, including Thailand. This study was designed to evaluate the efficacy of adding bismuth and probiotic to standard triple therapy for H. pylori eradication. MATERIALS AND METHODS In this prospective single center study, H. pylori infected gastritis patients were randomized to receive 7- or 14-day standard triple therapy plus bismuth with probiotic or placebo. Treatment regimen consisted of 30 mg lansoprazole twice daily, 1 g amoxicillin twice daily, 1 g clarithromycin MR once daily and 1,048 mg bismuth subsalicylate twice daily. Probiotic bacteria composed of Bifidobacterium lactis, Lactobacillus acidophilus and Lactobacillus paracasei. Placebo was conventional drinking yogurt without probiotic. CYP2C19 genotyping and antibiotic susceptibility tests were also done. H pylori eradication was defined as a negative 13C-urea breath test at least 2 weeks after completion of treatment. RESULTS One hundred subjects were enrolled (25 each to 7- and 14-day regimens with probiotic or placebo). Antibiotic susceptibility tests showed 36.7% metronidazole and 1.1% clarithromycin resistance. CYP2C19 genotyping revealed 40.8%, 49% and 10.2% were rapid, intermediate and poor metabolizers, respectively. The eradication rates of 7- or 14 regimens with probiotics were 100%. Regarding adverse events, the incidence of bitter taste was significantly lower in the 7- day regimen with the probiotic group compared with 7- day regimen with placebo (40% vs. 64%; p=0.04). CONCLUSIONS The 7-day standard triple therapy plus bismuth and probiotic can provide an excellent cure rate of H. pylori (100%) in areas with low clarithromycin resistance such as Thailand, regardless of CYP2C19 genotype. Adding a probiotic also reduced treatment-related adverse events.

Abstract
BACKGROUND Gastric cancer is the second leading course of cancer death worldwide and H. pylori infection is an important risk factor for gastric cancer development. This study was design to evaluate the clinical, pathological features, survival rate and prevalence of H. pylori infection in gastric cancer in Thailand. MATERIALS AND METHODS Clinical information, histological features, endoscopic findings and H. pylori status were collected from gastric cancer patients from Thammasat university hospital during June 1996-December 2011. H. pylori infection was assessed by histological evaluation, rapid urease test and serological test. Clinical information, endoscopic findings and histopathology of all patients were recorded and compared between patients with active or non-active H. pylori infection. RESULTS A total of 100 gastric cancer patients (55 men and 45 women with mean age of 55±16.8 years) were enrolled in this study. Common presenting symptoms were dyspepsia (74%), weight loss (66%), anemia (63%) and anorexia (38%). Mean duration of symptoms prior to diagnosis was 98 days. Overall prevalence of H. pylori infection was 83% and active H. pylori infection was 40%. 1-year and 5-year survival rates were 43% and 0%. There was no significant difference between active H. pylori infection in different locations (proximal vs non-proximal: 47.1% vs 48.5%; P-value=0.9, OR=0.9; 95%CI=0.3-3.1) and histology of gastric cancer (diffuse type vs intestinal type: 47.4% vs 50%; P-value=0.8, OR=0.9, 95%CI=0.3-2.7). However, linitis plastica was significantly more common in non-active than active H. pylori infection (27.9% vs 0%; P-value<0.0001, OR=13.3, 95%CI=3.2-64.5). Moreover, gastric cancer stage 4 was higher in non-active than active H. pylori infection (93% vs 50%, P-value<0.001). CONCLUSIONS Prevalence of H. pylori infection in Thai gastric cancer patients was high but active infection was low. Most gastric cancer patients presented in advance stage and had a grave prognosis. Screening for gastric cancer in high risk individuals might be an appropriate tool for early detection and improve the treatment outcome for this particular disease in Thailand.
