Evaluating Helicobacter pylori Infection as a Risk Factor for Iron Deficiency Anemia: A Case-Control Approach.

Background The medical community identifies () infection as a growing cause of extra-gastrointestinal manifestations, which primarily affect iron deficiency anemia (IDA). The purpose of this research was to analyze how infection relates to IDA through the case-control method. Method This study enrolled 48 individuals, divided into 24 (50%) cases of diagnosed IDA patients and 24 (50%) healthy controls who were matched by age and sex at Soo-Jung Hospital Doti, Rajpur Doti, Nepal. The study enrolled all subjects for laboratory examinations of blood tests, along with infection assessments via stool antigen testing or urea breath tests. The researchers documented dietary patterns, non-steroidal anti-inflammatory drug (NSAID) use, gastrointestinal symptoms, and bleeding history. The investigators analyzed the data through SPSS Version 22 (IBM Corp., Armonk, NY) and conducted independent t-tests and chi-square tests to compare groups, with statistical significance set at p < 0.05. Results Research findings indicated that subjects with IDA presented a higher rate of positivity, 21 (87.5%), compared to the control group, 7 (29.2%) (p < 0.001). The mean levels of hemoglobin, ferritin, and serum iron were significantly reduced in cases (9.7 g/dL versus 13.0 g/dL) (17.2 ng/mL versus 58.1 ng/mL), while they showed elevated total iron-binding capacity and decreased mean cellular volume levels. The proportion of patients with poor nutritional status and NSAID use was higher among participants who tested positive for . Conclusion The evidence indicated that infection establishes a direct link to the development of IDA. The combined assessment and therapy of infection in anemic patients demonstrated promise for proper management and anemia resolution, particularly when patients have an inadequate diet or use NSAIDs.
