J Infect Chemother 2024:S1341-321X(24)00258-7. [PMID: 39260772 DOI: 10.1016/j.jiac.2024.09.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 08/27/2024] [Accepted: 09/06/2024] [Indexed: 09/13/2024]
Abstract
BACKGROUND H. pylori infection is a common bacterial infection worldwide, but its prevalence varies widely between different regions and populations. The objective of this study was to determine the prevalence of H. pylori infection and associated risk factors among HIV-positive and HIV-negative individuals in northern Ethiopia. METHODS A cross-sectional study was conducted from June to September 2020 in four randomly selected health facilities located in the Tigray region of Ethiopia. A total of 463 study participants were enrolled, of whom 288 were HIV-positive and 175 were HIV-negative individuals. H. pylori stool antigen tests were performed to detect H. pylori infection. Additionally, CD4+ T cell counts were measured from only a certain number of participants. RESULTS The overall prevalence of H. pylori infection among enrolled study participants was 39.7 %. Notably, the H. pylori infection rate was significantly higher in HIV-positive patients (43.4 %) compared to HIV-negative individuals (33.7 %); χ2 = 4.27, p = 0.039. Higher H. pylori prevalence was observed in participants with higher CD4+ T cell counts in both HIV-positive and HIV-negative individuals. Khat chewing habit, education, and monthly income levels were significantly associated with H. pylori infection in HIV-negative individuals, while the association between Body mass index (BMI) and H. pylori infection was observed in HIV-positive patients, but not HIV-negative individuals. CONCLUSION This study demonstrates a higher prevalence of H. pylori infection in HIV-positive patients compared to HIV-negative individuals, emphasizing the importance of comprehensive diagnostics, patient care, and management of H. pylori infection in HIV-positive individuals.

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 Placenta previa increases the risks of obstetrical complications. Many studies have reported a link between various ABO blood types and pregnancy complications. This study is aimed at describing and comparing the characteristics and outcomes of women with placenta previa by ABO blood type. Methods Data for this study was obtained from a retrospective cohort study between January 1, 2014, and June 30, 2019, of all clinically confirmed placenta previa in a university-based tertiary medical center. Both types of A, B, O, AB, and combining O and non-O blood types were compared to the characteristics and outcomes. Results 1678 participants with placenta previa were included in this study. The highest participants were blood type O with 666 (39.7%), followed by type A with 508 (30.3%) and type B with 395 (23.5%), and the lowest participants were AB with 109 (6.5%). Blood type AB had a higher incidence of antepartum hemorrhage (p = 0.017), predelivery anemia (p = 0.036), and preterm birth (p = 0.015) in placenta previa women. Meanwhile, the incidence of rhesus D positive (97.9% vs. 95.8%, p = 0.012) and twins (5.0% vs. 2.7%, p = 0.011) was higher in the non-O group, and the incidence of neonatal asphyxia (5.9% vs. 9.2%, p = 0.016) was lower in the non-O group. Conclusion Type AB blood may be a potential risk factor for women with placenta previa. This finding may help provide any obstetrician to predict the risk of complication for placenta previa women by the ABO blood types.

Abstract
INTRODUCTION Human immunodeficiency virus (HIV) infection management has recently become more successful. While the life expectancy of HIV-infected patients increased, the prevalence of non-acquired immunodeficiency syndrome-defining cancers, such as gastric cancer, also increased. Helicobacter pylori is associated with gastric cancer, the most common cancer and the fourth leading cause of cancer-related deaths in South Korea, which has the highest incidence of chronic gastric mucosa inflammation. Here, the seroprevalence and risk factors of H. pylori infection in Korean HIV-infected patients were evaluated. METHODS Three hundred HIV-infected patients attending the Outpatient Department of Pusan National University Hospital were prospectively enrolled from October 2018 to February 2019. Socio-demographic information was evaluated using questionnaires, and the serological status of H. pylori infection was analyzed for anti-H. pylori IgG antibodies. RESULTS The overall seropositivity of H. pylori was 32.7%, and 254 patients (84.7%) were male. The risk factors significantly associated with H. pylori seropositivity were: age of 40-49 years (odds ratio [OR] = 5.00; 95% confidence interval [CI] 1.30-19.17), age of 50-59 years (OR = 3.93; 95% CI 1.05-14.73), CD4 cell counts of 350-500/μL (OR = 4.23; 95% CI 1.53-11.65), CD4 cell counts ≥500/μL (OR = 2.78; 95% CI 1.15-6.72), and a weekly average alcohol consumption of at least one alcoholic beverage (OR = 1.78; 95% CI 1.05-2.99). CONCLUSIONS The seroprevalence of H. pylori is significantly associated with alcohol consumption, high CD4 cell count, and the age group of 40-59 years.

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
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
The ABH and Lewis antigens were among the first of the human red blood cell polymorphisms to be identified and, in the case of the former, play a dominant role in transfusion and transplantation. But these two therapies are largely twentieth century innovations, and the ABH and related carbohydrate antigens are not only expressed on a very wide range of human tissues, but were present in primates long before modern humans evolved. Although we have learned a great deal about the biochemistry and genetics of these structures, the biological roles that they play in human health and disease are incompletely understood. This review and its companion, to appear in a later issue of Vox Sanguinis, will focus on a few of the biologic and pathologic processes which appear to be affected by histo-blood group phenotype. The first of the two reviews will explore the interactions of two bacteria with the ABH and Lewis glycoconjugates of their human host cells, and describe the possible connections between the immune response of the human host to infection and the development of the AB-isoagglutinins. The second review will describe the relationship between ABO phenotype and thromboembolic disease, cardio-vascular disease states, and general metabolism.

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.

Abstract
Background Helicobacter pylori (H. pylori) is implicated for the causation of gastrointestinal tract infections including gastric cancer. Although the infection is prevalent globally, the impact is immense in countries with poor environmental and socioeconomic status including Ethiopia. Epidemiological study on the magnitude of H. pylori and possible risk factors has priceless implication. Therefore, in this study, we determined the prevalence and risk factors of H. pylori infection in the resource-limited area of northwest Ethiopia. Methods A prospective cross-sectional study was conducted on northwest Ethiopia among 201 systematically selected dyspeptic patients. Data were collected using a structured and pretested questionnaire, and stool and serum samples were collected and analyzed by SD BIOLINE H. pylori Ag and dBest H. pylori Disk tests, respectively. Chi-square test was performed to see association between variables, and binary and multinomial regression tests were performed to identify potential risk factors. P values <0.05 were taken statistically significant. Result Prevalence of H. pylori was found to be 71.1% (143/201) and 37.3% (75/201) using the dBest H. pylori Test Disk and SD BIOLINE H. pylori Ag test, respectively. H. pylori seropositivity, using dBest H. pylori Disk tests, is significantly associated in age groups <10 years (P=0.044) and married patients (P=0.016). In those patients with H. pylori (a positive result with either the Ab or Ag test), drinking water from well sources had 2.23 times risk of getting H. pylori infection (P=0.017), and drinking coffee (1.51 (0.79–2.96, P=0.025)) and chat chewing (1.78 (1.02–3.46, P=0.008) are the common risk factors. Conclusion The present study discovered considerable magnitude of H. pylori among the dyspeptic patients in the study area. H. pylori infection is frequent in individuals drinking water from well sources, and thus, poor sanitation and unhygienic water supply are contributing factors. Policies aiming at improving the socioeconomic status will reduce potential sources of infection, transmission, and ultimately the prevalence and incidence of H. pylori.

Abstract
Background Helicobacter pylori (H.pylori) infection is predominantly acquired in childhood from family members. The infection can cause dypepepsia, chronic and acute gastritis and gastric cancer. Dyspepsia is the most common illness in the Ethiopian population visiting outpatient department of health facilities, and it has also been associated with H.pylori infection. The aim of this study was to assess the magnitude of H.pylori and its associated factors among dyspeptic patients who visited University of Gondar Hospital Outpatient Department. Materials and Methods An institutional-based cross-sectional study was conducted on 354 dyspeptic patients. A systematic random sampling technique was employed to select study participants. Data were collected by using structured questionnaire via face-to-face interview. H.pylori infection was diagnosed using stool antigen test method. The data were entered into Epi info version 3.5.3 and transferred to Statistical Package for Social Sciences version 20. Both Bivariable and multivariable binary logistic regression analyses were performed to see the effect of independent variables on the dependent variable. Result Of the total study participants, 201(56.8%), 195(55.1%) and 182(51.4%) were married, urban residents and females, respectively. The overall magnitude of H.pylori infection was 37.6%. In bivariable logistic regression analysis, sex and marital status were significantly associated with H.pylori infection, but in multivariable logistic regression analysis only marital status was significantly associated with H.pylori infection. Conclusion The magnitude of H.pylori infection is high indicating that it is a public health problem in the study to area. According to this study, none of the variables were significantly associated with H.pylori infection. Hence, effective preventive, control and screening strategies need to be designed to reduce the burden of the disease.

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: 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
Background Helicobacter pylori infection is a major public health problem affecting half of the world's population. The prevalence of H. pylori varies in different societies and geographical locations. Thus, timely information on H. pylori epidemiology is critical to combat this infection. This study aimed to determine the seroprevalence and trend of H. pylori infection over a period of 5 years among dyspeptic patients at Bahir Dar Felege Hiwot Referral Hospital, Northwest Ethiopia. Methods A retrospective analysis of consecutive dyspeptic patients' records covering the period between January 2009 and December 2013 was conducted. The hospital laboratory generated the data by a serological method of detecting the antibodies for H. pylori from serum by a one-step rapid test device. Chi-square analysis was used to identify significant predictors. A P-value of <0.05 was considered as statistically significant. Results Among all the study subjects, 2,733 (41.6%) were found to be seropositive. The seroprevalence was significantly higher in males (43.2%) than in females (39.9%) (χ2=9; P=0.002). In terms of age groups of the patients, high rates of H. pylori were found among the participants older than 60 years (57%) (χ2=36.6; P≤0.00001). The trend analysis of H. pylori prevalence revealed a fluctuating prevalence; it was 44.5% in the year 2009 and decreased to 34% and 40% in the years 2010 and 2011, respectively. However, there was an increment to 52.5% in the year 2012, and then it decreased to 30.2% in the year 2013. Conclusion This study showed high seroprevalence of H. pylori among the dyspeptic patients in Bahir Dar Felege Hiwot Referral Hospital. The trend of the seroprevalence varied from year to year in the 5 consecutive years. Considering this, designing appropriate prevention and control strategies is mandatory.

Abstract
BACKGROUND Gastric cancer as one of the most important diseases affecting health in all worldwide. Current studies have confirmed associations of cytokine gene polymorphisms with the risk of gastric cancer development. The current research aimed to assess the association of IL-1B+3954 genotypes with the risk of gastric cancer in the Iranian population. MATERIALS AND METHODS This case-control study covered 49 gastric cancer patients compared to 53 cancer free individuals as a control group. Genomic-DNA extraction was carried out from bioptic samples of patients and peripheral blood of healthy volunteers. Polymorphism of IL-1B +3954 genotypes were analysed with a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. RESULTS The frequencies of IL-1B +3954 A1A1, A1A2 and A2A2 genotypes in healthy individuals were 26.4, 66 and 7.6 %, respectively. However, in gastric cancer patients, A1A1, A1A2 and A2A2 with 4.1, 51 and 44.9% were observed (p<0.05). CONCLUSIONS The findings of our results show a positive association between the IL-1B+3954 genotype distribution and the risk of gastric cancer disease in the Iranian population.

Abstract
Blood group antigens represent polymorphic traits inherited among individuals and populations. At present, there are 34 recognized human blood groups and hundreds of individual blood group antigens and alleles. Differences in blood group antigen expression can increase or decrease host susceptibility to many infections. Blood groups can play a direct role in infection by serving as receptors and/or coreceptors for microorganisms, parasites, and viruses. In addition, many blood group antigens facilitate intracellular uptake, signal transduction, or adhesion through the organization of membrane microdomains. Several blood groups can modify the innate immune response to infection. Several distinct phenotypes associated with increased host resistance to malaria are overrepresented in populations living in areas where malaria is endemic, as a result of evolutionary pressures. Microorganisms can also stimulate antibodies against blood group antigens, including ABO, T, and Kell. Finally, there is a symbiotic relationship between blood group expression and maturation of the gastrointestinal microbiome.

Abstract
Background Helicobacter pylori infection is associated with anemia. Understanding the magnitude of H.pylori infection and its association with anemia is important in the management of anemic patients. The aim of this study was to assess the association between H.pylori infection and anemia among dyspeptic patients. Methods A cross-sectional study was conducted in Butajira Hospital, Southern Ethiopia among 401 systematically dyspeptic patients. A structured questionnaire was used to collected data about the patient characteristics. Blood samples were analyzed for red blood cell parameters. Stool samples were assessed for the presence of H.pylori antigens and the presence of intestinal helminthes. Data were summarized in frequencies (%) and mean (SD) as appropriate. Chi-square test, logistic regression and independent t-tests were used in the analysis as needed. In all cases P-value <0.05 was considered as statistically significant. Results The overall prevalence of H. pylori infection was 52.4% and it was significantly associated with age, presence of intestinal parasites, smoking habit, alcohol drinking habit and body mass index. The prevalence of anemia among H.pylori infected patients (30.9%) was significantly (P < 0.001) higher than uninfected patients (22.5%). The mean (SD) values of HGB, MCV, MCH, MCHC, HCT and RBC count was significantly different between H.pylori infected and uninfected patients. Conclusion This study showed high prevalence of H.pylori infection among dyspeptic patients and this was associated with age and some behavioral characteristics of the patients. H.pylori infected patients showed high rate of anemia prevalence as compared to their H.pylori unifected counter parts. From this study it can be recommended that intervention activities related to the behavioral characteristics and prevention of intestinal parasitic infections should be in place. The cross sectional nature of the study has a limitation to show cause and effect associations and hence association between H.pylori infections with anemia need to be investigated in cohort type studies.

Abstract
BACKGROUND Helicobacter pylori is the main etiology of peptic ulcers and chronic gastritis. Various studies showed that blood type 'O' is more common among patients with peptic ulcer. The aim of this study was to determine the seroprevalence of H. pylori antibodies and its relationship with ABO/Rhesus blood groups, age, sex and residence of symptomatic patients in southern Ethiopia. METHODS A cross-sectional study was conducted in a total of 408 consecutive patients with upper abdominal complaints at Hawassa University Hospital from October 2012 to January 2013. Data on demographic factors was collected from all participants using questionnaires. Blood samples were also collected and tested for ABO and Rh blood group phenotype using hemagglutination test and for anti-H. pylori antibody (IgG) using two different ELISAs.. RESULTS The overall seroprevalence of H. pylori infection was 83.3% (340/408), and it was significantly higher in rural (71.2%) compared to urban residents (28.8%) (p=0.008). Participants with blood group AB, A, O, B, and Rh positive had H. pylori prevalence of 88.9, 84.2, 83.7, 80.9, and 83.5%, respectively. H. pylori infection was not significantly influenced by age, sex, occupation, educational status and ABO/ Rh status (p>0.05). CONCLUSION The high seroprevalence of H. pylori infection especially among rural residents calls for immediate intervention measures so that its clinical consequences could be minimized. ABO/Rh blood group was not found to be associated with H. pylori infection.

Abstract
Background: This study assessed the seroprevalence of Helicobacter pylori antibodies among Iranian patients with human immunodeficiency virus (HIV) infection. It also examines whether anti H. pylori seroprevalence was associated with the severity of the HIV infection or the antiretroviral treatment. Material and Methods: A total of 114 HIV-infected patients and 114 age and sex-matched controls, without symptoms referable to upper gastrointestinal tract were recruited. Blood samples were obtained from all subjects. Serum IgG and IgA against H. pylori measured using the enzyme-linked immunosorbent assay (ELISA). Results: The rate of anti H. pylori IgG seropositivity was 57.9% in HIV-infected patients and 28.95% in controls (P < 0.001), while the rate of IgA seropositivity was 2.64% in HIV patients and 31.57% in controls (P < 0.001). Although there was an increasing trend of higher IgG and IgA titre by increasing CD4 cell count in HIV-positive patients, it was not reach statistical significance. There was no statistical difference in the serology of anti H. pylori IgG and IgA between patients receiving antiretroviral therapy comparing untreated HIV patients. Conclusions: This study showed higher seroprevalence of H. pylori IgG along with lower seroprevalence of H. pylori IgA in HIV-positive patients compared matched controls.

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

Int J Infect Dis 2009; 14:e322-7. [PMID: 19699671 DOI: 10.1016/j.ijid.2009.03.036] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2008] [Revised: 03/05/2009] [Accepted: 03/22/2009] [Indexed: 10/20/2022] Open
Abstract
OBJECTIVE A significant number of HIV-1 patients experience poor immune reconstitution despite long-term viral suppression with highly active antiretroviral therapy (immunological non-responders). The aims of the present study were to determine whether eradication of Helicobacter pylori could facilitate a better immune reconstitution in these patients. METHODS Forty-nine immunological non-responder HIV-1 patients were evaluated by (13)C-urea breath test (UBT) for the presence of active H. pylori infection. They were all asymptomatic. The UBT was positive in 26 (53%) of them. Eleven patients (group 1) were treated with a combination of omeprazole 20mg bid, amoxicillin 1g bid and clarithromycin 500mg bid for 14 consecutive days. Eight weeks later, successful eradication was proven by a repeat negative UBT in all 11 patients. The remaining 15 (group 2) refused the H. pylori eradication treatment. All 26 patients were followed for 24 months and evaluated for blood CD4 and CD8 cell counts and percentages and for plasma HIV-1 viral load. RESULTS At the time of H. pylori diagnosis and eradication (baseline), CD4 and CD8 cell counts were similar in both study groups. All 11 H. pylori eradicated patients (group 1) had a significant increase in CD4 cell count starting 3 months and peaking 12-18 months after H. pylori eradication. Thereafter, CD4 levels gradually declined. Nevertheless, 24 months after triple therapy it was significantly higher than prior to H. pylori eradication. Parallel reciprocal changes were observed in CD8 cell counts. There were no significant changes in either CD4 or CD8 cell counts in group 2 patients. None of the patients of group 1 demonstrated virological failure, while four (26.7%) group 2 patients experienced virological failure requiring change of highly active antiretroviral therapy (HAART) regimen. CONCLUSION Triple therapy for H. pylori eradication is associated with a significant, although possibly transient immune reconstitution in HAART-treated HIV-1 patients with viral suppression without immunological response.

Abstract
We estimated the prevalence of Helicobacter pylori infection, chronic gastritis, atrophy, and intestinal metaplasia in dyspeptic patients from Maputo Central Hospital, Mozambique and evaluated the relationship between infection and histopathological features of chronic gastritis. Biopsies from 109 consecutive patients observed in 2005-2006 were collected from antrum, incisura angularis, and corpus for histopathological study according to the Modified Sydney system. H. pylori infection was assessed by histology and polymerase chain reaction. H. pylori prevalence was 94.5%. Chronic gastritis was the most frequent diagnosis (90.8%). Degenerative surface epithelial damage was associated with higher H. pylori density. Glandular atrophy (8.3%) and intestinal metaplasia (8.3%) were infrequent. Our results confirm previous observations in African countries with high prevalence of H. pylori infection and low rates of gastric cancer: high frequency of chronic H. pylori-associated gastritis with very low frequency of gastric atrophy and intestinal metaplasia.

Abstract
BACKGROUND To determine the magnitude of Helicobacter pylori infection in patients with gastrointestinal complaints in Turkey. METHODS We studied 1680 patients with variable gastrointestinal complaints. The H. pylori infection status was determined using C-14 urea breath test (UBT). Overall, 1567 patients (548 male, 1019 female; age range 4-80 years, mean 29.37 +/- 17.30 years) were included in this study. The relationship between H. pylori positivity and age, sex, sociodemographic characteristic, blood groups, and gastrointestinal diagnosis was determined. RESULTS H. pylori positivity was found to be 68%. The difference in positivity rates between age groups 4-9 years and other groups was statistically significant (p = .001). H. pylori positivity was 67.7% in males and 68.2% in females (p = .865). H. pylori positivity was 72.1, 65.1, 70, and 68.4% in blood groups A, B, AB, and O (p = .703), and 68.9% and 76.3% in Rh (+) and Rh (-) blood subgroups, respectively (p = .292). There was no statistically significant difference between H. pylori positivity and gastrointestinal diagnosis (p = .980). There was significant association between increased number of household members and low socioeconomic status, and H. pylori positivity (p < .001). Living in rural and suburban area was significantly associated with H. pylori positivity compared with living in urban. CONCLUSIONS H. pylori infection positivity rate was 68% in symptomatic subjects in Turkey and the positivity rate was significantly lower at age 4-9 years than the other age groups. It was not related to gender, ABO, and Rh blood groups and gastrointestinal diagnosis. Low socioeconomic conditions and living in rural and suburban area were significantly associated with H. pylori positivity.
