Association between alcohol consumption, cigarette smoking, and Helicobacter pylori infection in Iraqi patients submitted to gastrointestinal endoscopy

Abstract

Objective: The aim of this paper was to assess the prevalence and association between H. pylori infection and alcohol, or cigarette use among Iraqi patients. Methods: 115 individuals needed upper gastrointestinal endoscopies in total. Reverse transcription polymerase chain reaction (RT-PCR), urea breath test, rapid urease test, CagA-IgG, and culture were all used to confirm H. pylori infection. The information on alcohol consumption, smoking, sex, and age was collected using a standard questionnaire. Results: The gold standard test, RT-PCR, was used to detect H. pylori infection in 81 (70.4%) of patients. H. pylori infection was not affected by age (OR: 0.976; CI: 95% (0.944-1.009; P > 0.05), sex (OR: 1.26, 95% CI: 0.57–2.75; P > 0.05), or alcohol intake (OR: 0.293; CI: 95% (0.081-1.058; P > 0.05) according to the binary logistic regression analysis. Additionally, there was a considerable inverse association between smoking and H pylori infection (OR: 0.094; CI: 95% (0.025-0.352; P < 0.05). According to binary logistic regression analysis, both smoking (OR: 0.036; CI: 95% (0.007-0.182; P < 0.05) and alcohol intake (OR: 0.179; CI: 95% (0.041-0.988; P < 0.05) were inversely and significantly related with H. pylori illness whereas H. pylori infection did not alter with age (OR: 1.001; CI 95% (0.959-1.044; P > 0.05) in the male subgroup. Conclusions: According to the study, males who smoke and drink are more likely to have H. pylori infections. Furthermore, there was no positive association between age and H. pylori infection.

The Suitability of Stool Antigen Testing in the Detection of Helicobacter pylori in a Regional and Rural Area of Australia

“…This is appropriate as Southern.IML Pathology services 90% of the pathology tests in this region indicating that the data obtained was a good representation of the testing in the region. The highest estimated prevalence of H. pylori infection was 1.7% in socioeconomic percentile 4, which is considerably lower than the anticipated prevalence values [38]. This may be explained by demographic variations in Southern.IML Pathology's major areas of activity as well as unaccounted testing performed by competing pathology services in the same and peripheral areas.…”

Influence of selected non-antibiotic pharmaceuticals on antibiotic resistance gene transfer in Escherichia coli

“…This dilemma is usually attributed to various causes such as: availability of antibiotics everywhere and health care persons may suffer from lack of education. Also, many patients stop treatment with antibiotics upon feeling better, use leftover antibiotics and may use antibiotics in treating viral infection [30][31][32][33].…”

Exposure of Helicobacter pylori to clarithromycin in vitro resulting in the development of resistance and triggers metabolic reprogramming associated with virulence and pathogenicity

“…Helicobacter pylori is a Gram-negative microaerophilic bacterium that causes gastric diseases, such as gastritis and peptic ulcers, and is associated with stomach cancer [ 12 , 13 ]. The ability of H .…”

“…Helicobacter pylori is a Gram-negative microaerophilic bacterium that causes gastric diseases, such as gastritis and peptic ulcers, and is associated with stomach cancer [12,13]. The ability of H. pylori to adapt and thrive in the harsh acidic environment of the stomach is one of the most remarkable elements of its biology [14].…”
