Abstract
Chronic infection of Helicobacter pylori represents a key factor in the etiology of gastrointestinal diseases, with high endemicity in South Asia. The present study aimed to determine the prevalence of H. pylori among dyspeptic patients in north-central Bangladesh (Mymensingh) and analyze risk factors of infection and antimicrobial resistance (AMR) determinants in the pathogen. Endoscopic gastrointestinal biopsy samples were collected from dyspeptic patients for a one-year period from March 2022 and were checked for the presence of H. pylori via the rapid urease test and PCR and further analyzed for the status of virulence factors vacA/cagA and genetic determinants related to AMR via PCR with direct sequencing or RFLP. Among a total of 221 samples collected, 80 (36%) were positive for H. pylori, with the vacA+/cagA+ genotype being detected in almost half of them. H. pylori was most prevalent in the age group of 41-50-year-olds, with it being more common in males and rural residents with a lower economic status and using nonfiltered water, though the rates of these factors were not significantly different from those of the H. pylori-negative group. Relatively higher frequency was noted for the A2147G mutation in 23S rRNA, related to clarithromycin resistance (18%, 7/39). Amino acid substitutions in PBP-1A (T556S) and GyrA (N87K and D91N) and a 200 bp deletion in rdxA were detected in samples from some patients with recurrence after treatment with amoxicillin, levofloxacin, and metronidazole, respectively. The present study describes the epidemiological features of H. pylori infection in the area outside the capital in Bangladesh, revealing the spread of AMR-associated mutations.

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 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.
