Abstract
Helicobacter pylori (HP) infection presents a significant threat to global health with serious associated morbidities. This study aimed to assess awareness, attitudes, and practices related to HP in the Kingdom of Saudi Arabia (KSA) through a survey-based cross-sectional study involving 2,541 respondents. We used a structured online questionnaire to gather data on personal and sociodemographic characteristics, as well as HP-related knowledge, attitudes, and practices. The survey was distributed through various social media platforms. The results revealed that 59.4% of respondents demonstrated good knowledge about HP, with a mean knowledge score of 3.7 ± 1.0 out of 5. Knowledge gaps were particularly evident regarding the contagiousness and transmission modes of HP. The mean attitude score was 12.2 ± 2.2 out of a maximum score of 15. In total, 37.6% of respondents reported ever being tested for HP, with 54.2% testing positive. Among those treated for HP, only 79% received antibiotic therapy and 37.8% received acid-reducing medications. Knowledge levels were significantly higher among younger and highly educated respondents (P < 0.001), and respondents with higher knowledge scores also had higher attitude scores than those with lower knowledge scores (12.6 ± 2.0 vs. 11.6 ± 2.0, P < 0.001). Individuals who had undergone HP testing had significantly higher knowledge levels than those who did not (62.3 vs. 57.8, P = 0.024). These findings underscore the urgent need for raising the population's awareness regarding the risks, prevention, and management of HP infection through targeted educational strategies.

Systematic Retesting for Helicobacter pylori: The Potential Overestimation of Suppressive Conditions. BIOMED RESEARCH INTERNATIONAL 2022; 2022:5380001. [PMID: 35509714 PMCID: PMC9060991 DOI: 10.1155/2022/5380001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Accepted: 03/28/2022] [Indexed: 12/03/2022]
Abstract
Background and Aims In contrast to guideline recommendations, endoscopic testing for Helicobacter pylori is frequently performed under Helicobacter pylori suppressive conditions, e.g., intake of proton-pump inhibitors (PPI), preceded antibiotic treatment, or recent gastrointestinal bleeding. Our study's aim was to retest patients with—under suppressive conditions—negative test results. This was carried out in order to examine the rate of false negative tests previously gathered under suppressive conditions. Methods The trial was conducted in a large patient collective in a university hospital. Every elective esophagogastroduodenoscopy from in- and outpatients was included. Prior to endoscopy, suppressive conditions were collected via standardized questionnaire. If Helicobacter pylori testing was indicated, both helicobacter urease test and histology were performed in analogy to the Sydney classification. In case of a negative result under suppressive conditions, the patient was reinvited after, if possible, withdrawal of suppressive condition in order to perform a urea breath test (UBT). Results 1,216 patients were included (median 59 years, 72.0% inpatients, 28.0% outpatients). Overall, 60.6% (737) were under Helicobacter pylori suppressive conditions. The main suppressive condition was intake of PPIs (54.5%). In 53.7% (653) of all included cases, Helicobacter pylori testing was performed. Of those, 14.1% (92) had a positive test, and 85.9% (561) were negative. Out of the patients with negative result, 50.8% (285) were tested under suppressive conditions and consequently invited for retesting via UBT. In 20.4% (45), suppressive conditions could not be ceased. In 22.8% (65), retesting was conducted. Of those, 98.5% (64) congruently presented a negative result again, and only 1.5% (1) was positive for Helicobacter pylori. Conclusion Many patients undergoing esophagogastroduodenoscopy in everyday clinical practice are tested for Helicobacter pylori under suppressive conditions leading to a potentially higher risk of false negative results. However, our research shows that this issue might be overestimated.

Characteristics of gastric precancerous conditions and Helicobacter pylori infection among dyspeptic patients in north-eastern Iran: is endoscopic biopsy and histopathological assessment necessary? BMC Cancer 2021; 21:1143. [PMID: 34702194 PMCID: PMC8546943 DOI: 10.1186/s12885-021-08626-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Accepted: 07/26/2021] [Indexed: 01/06/2023] Open
Abstract
Background Early detection and appropriate treatment of precancerous, mucosal changes could significantly decrease the prevalence of life-threatening gastric cancer. Biopsy of the normal-appearing mucosa to detect Helicobacter pylori and these conditions is not routinely obtained. This study assesses the prevalence and characteristics of H. pylori infection and precancerous conditions in a group of patients suffering from chronic dyspepsia who were subjected to gastric endoscopy and biopsy mapping. Methods This cross-sectional study included dyspeptic patients, not previously treated for H. pylori, undergoing esophagogastroduodenoscopy (EGD) with their gastric endoscopic biopsies obtained for examination for evidence of H. pylori infection and precancerous conditions. Demographic and clinical data on the gender, smoking, opium addiction, alcohol consumption, medication with aspirin, corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDs) and family history of cancer were collected by interviewing the patients and evaluating their health records. The cohort examined consisted of 585 patients with a mean (SD) age of 48.0 (14.46) years, 397 (67.9%) of whom were women. Results H. pylori infection was identified in 469 patients (80.2%) with the highest prevalence (84.2%) in those aged 40–60 years. Opium addiction correlated with a higher a H. pylori infection rate, while alcohol consumption was associated with a lower rate by Odds Ratio 1.98 (95% CI 1.11–3.52) and 0.49 (95% CI 0.26–0.92), respectively. The prevalence of intestinal metaplasia, gastric atrophy and gastric dysplasia was 15.2, 12.6 and 7.9%, respectively. Increased age, positive H. pylori infection, endoscopic abnormal findings and opium addiction showed a statistically significant association with all precancerous conditions, while NSAID consumption was negatively associated with precancerous conditions. For 121 patients (20.7% of all), the EGD examination revealed normal gastric mucosa, however, for more than half (68/121, 56.2%) of these patients, the histological evaluation showed H. pylori infection, and also signs of atrophic mucosa, intestinal metaplasia and dysplasia in 1.7, 4.1 and 1.7%, respectively. Conclusion EGD with gastric biopsy mapping should be performed even in the presence of normal-appearing mucosa, especially in dyspeptic patients older than 40 years with opium addiction in north-eastern Iran. Owing to the high prevalence of precancerous conditions and H. pylori infection among patients with dyspepsia in parts of Iran, large-scale national screening in this country should be beneficial.

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
Helicobacter pylori is a chronic bacterial infection that can lead to peptic ulcer disease, chronic gastritis, and gastric cancer. Its prevalence in the United States is lower than in most of the world, although specific populations are at particular risk for disease-related complications, including those with lower socioeconomic status and older adults. Since its discovery, there have been advances in H. pylori diagnosis and treatment, which are the focus of this review for general practice. Practice guidelines have expanded the role for treatment, despite traditional management algorithms resulting in diminished effectiveness as a result of increasing antibiotic resistance. In this context, new approaches warrant discussion. As such, this review aims to provide a clinical context and framework for the testing and rational treatment of H. pylori infection consistent with the available evidence.
