Concurrence of Helicobacter pylori Infection and Its Associated Factors in Korean Couples
1Department of Family Medicine, Kosin University Gospel Hospital, Busan, Korea.
Background:
This study evaluated the prevalence of Helicobacter pylori infection and the risk factors associated with H. pylori transmission among spouses.
Methods:
We assessed the spousal concurrence of H. pylori infection using the Campylobacter-like organism (CLO) test under gastro-endoscopy in 132 couples. Based on the CLO test results, participants were categorized into H. pylori concurrent and independent groups. The chi-square test and Student t-test were performed for demographic comparisons between the concurrent and independent H. pylori groups. In addition, multivariate logistic regression analysis was performed to identify factors associated with concurrent H. pylori infection.
Results:
The study revealed that the concurrence rate of H. pylori infection was 42.4% in married Korean couples. The odds ratio (OR) derived from the concurrence of H. pylori infection tended to decrease in older couples (OR, 0.975; 95% confidence interval [CI], 0.949-1.002; P=0.072). Gastric erosion was also associated with a decreased OR for concurrent infection (OR, 0.488; 95% CI, 0.295-0.808; P=0.005). Conversely, active duodenal ulcers were associated with an increased OR for concurrent infections (OR, 6.501; 95% CI, 1.267-33.346; P=0.025). Duodenal ulcer scars tended to increase the OR of concurrent infections (OR, 1.392; 95% CI, 0.815-2.380; P=0.226).
Conclusion:
Spousal transmission and concurrence of H. pylori infection were negatively associated with gastric erosion; however, they were positively associated with active duodenal ulcers. Further studies are warranted to elucidate the mechanisms underlying these findings.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
