Comparison of Effects of Different Courses of Proton Pump Inhibitors in Treatment of Erosive Esophagitis / 胃肠病学

ABSTRACT

Background: Gastroesophageal reflux disease (GERD) is a commonly seen disease of digestive system, and its prevalence is increasing year by year. Xinjiang is located in the northwestern part of China and is a multi-ethnic region. The diets consumed are mainly meat, sweet food and strong tea, and the incidence of GERD is high in Xinjiang. Aims: To compare the efficacy of 4-week and 8-week courses of proton pump inhibitors (PPI) in the treatment of mild erosive esophagitis (EE) and to explore the factors influencing the efficacy of PPI. Methods: A total of 151 LA-A/B grade EE patients from November 2020 to February 2021 at General Hospital of Xinjiang Military Region were recruited, and grading of gastroesophageal reflux disease questionnaire (GerdQ), STOP-Bang questionnaire, Pittsburgh sleep quality index (PSQI), self-rating anxiety scale (SAS), self-rating depression scale (SDS) were performed. Patients received 40 mg qd esomeprazole for 8 weeks. The factors influencing the efficacy of PPI were analyzed. Results: No significant difference in symptom remission rate was found between 4-week and 8-week courses of PPI (74.1% vs. 81.3%, P=0.163). Multivariate analysis results showed that high risk of obstructive sleep apnea-hypopnea syndrome (OSAHS) and presence of hiatal hernia were the factors influencing the efficacy of 4-week course of PPI (P<0.05) and presence of hiatal hernia was the factor influencing the efficacy of 8-week course of PPI (P<0.05). Conclusions: Symptom remission rates are similar between 4-week and 8-week courses of PPI for mild EE. The presence of hiatal hernia and high risk of OSAHS can increase the difficulty and prolong the course of PPI in the treatment of EE.
