Factors Associated with Potassium-Competitive Acid Blocker Non-Response in Patients with Proton Pump Inhibitor-Refractory Gastroesophageal Reflux Disease.

Background/aims: Approximately 20-40% of patients with gastroesophageal reflux disease (GERD) are refractory to proton pump inhibitor (PPI) treatment. The acid-inhibitory effect of vonoprazan, a novel potassium-competitive acid blocker (P-CAB), is significantly greater when compared to the effect of PPIs. We investigated the efficacy of vonoprazan treatment for PPI-refractory GERD and factors associated with P-CAB non-response.

Sleep disturbances in Japanese patients with inflammatory bowel disease and their impact on disease flare.

Background: Several studies have reported a significant association between sleep disturbance and inflammatory bowel disease (IBD). The aim of the present study is to compare the clinical characteristics and the health-related quality of life (HR-QOL) of Japanese IBD patients with or without sleep disturbances, and to investigate the risk factors for disease flare in these patients.

Methods: IBD patients were asked to complete a self-administered questionnaire including the Pittsburg sleep quality index and the 8-item short-form health survey.

Associations among gastroesophageal reflux disease, psychological stress, and sleep disturbances in Japanese adults.

Background And Aim: Gastroesophageal reflux disease (GERD) and psychological stress are associated with sleep disturbances. The aim of the present study was to examine the prevalence of sleep disturbances, anxiety, and depression by GERD subtypes and to identify factors associated with sleep disturbances in general population.

Methods: A total of 2002 Japanese subjects, who underwent annual health checkups, were enrolled and asked to fill out a questionnaire, including the frequency scale for the symptoms of GERD (FSSG), Athens Insomnia Scale (AIS), Rome III questionnaire, and Hospital Anxiety and Depression Scale (HADS).

Characteristics of Sleep Disturbances in Patients with Gastroesophageal Reflux Disease.

Objective Gastroesophageal reflux disease (GERD) is strongly associated with sleep disturbances; however, the detailed differences in the characteristics of sleep disturbances between GERD and non-GERD patients are unknown. The aim of the present study was to analyze the clinical characteristics as well as health-related quality of life in GERD and non-GERD patients with sleep disturbances. Methods Three hundred and fifty patients, including 124 patients with GERD and 226 patients without GERD, completed a self-administered questionnaire that evaluated clinical information.
