Effects of lansoprazole and omeprazole Combined With Antimicrobial Agents on Gastric Juice pH and Inflammatory Factors in Elderly Patients With Hp Positive Gastric Ulcer.

Background: Helicobacter pylori (Hp) is one of the most prevalent pathogenic microorganisms in the world, which is related to gastric ulcer. Objective: To observe the effect of lansoprazole and omeprazole combined with antibiotics on gastric juice pH and inflammatory factors in elderly patients with Hp positive gastric ulcer. Design: This study was a prospective observation study. Setting: This study was performed in Department of Gastroenterology, First Affiliated Hospital of Soochow University. Participants: One hundred and ten elder patients with Hp positive gastric ulcer admitted to our hospital from January 2019 to May 2020. Intervention: The control group was treated with omeprazole combined with antibiotics, and the observation group was treated with lansoprazole combined with antibiotics. Primary outcome measures: The level of gastric juice pH, interleukin-1 (IL-1), interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α) and heat shock protein-70 (HSP-70). Methods: The changes of gastric juice pH value, IL-1, IL-8, TNF-α and HSP-70 levels before and after treatment were detected in the two groups. The total effective rate, Hp eradication rate, mature type of regenerated mucosal tissue surrounding ulcer and adverse reaction rate were statistically analyzed. Results: The total effective rate and Hp eradication rate in the observation group were higher than those in the control group, while the adverse reaction rate in the observation group was lower than that in the control group (P < .05). After treatment, the pH value of gastric juice and HSP-70 in the observation group were higher than those in the control group, while the IL-1, IL-8 and TNF-α were lower than those in the control group (P < .05). The mature type of regenerated mucosal tissue structure around ulcer in the observation group was better than that in the control group (P < .05). Conclusion: The overall effect of lansoprazole combined with antibiotics in the treatment of Hp positive gastric ulcer in the elderly is better than that of omeprazole combined with antibiotics.
