Long-term proton pump inhibitor therapy and risk of hip fracture

CONTEXT: Proton pump inhibitors (PPIs) may interfere with calcium absorption through induction of hypochlorhydria but they also may reduce bone resorption through inhibition of osteoclastic vacuolar proton pumps. OBJECTIVE: To determine the association between PPI therapy and risk of hip fracture. DESIGN, SETTING, AND PATIENTS: A nested case-control study was conducted using the General Practice… Read more »

Increased risk of fundic gland polyps during long-term proton pump inhibitor therapy

BACKGROUND: It is controversial whether proton pump inhibitor use leads to fundic gland polyp development. AIM: To determine whether fundic gland polyp development is due to proton pump inhibitor use and to investigate mechanisms involved. METHODS: Proton pump inhibitor use and the presence of fundic gland polyps were assessed in consecutive patients undergoing oesophagogastroduodenoscopy. Biopsies… Read more »

Proton pump inhibitors reduce gallbladder function

BACKGROUND: In the authors’ previous study of gallbladder function before and after fundoplication, 58% of the patients demonstrated preoperative gallbladder motor dysfunction, and 86% of those retested after operation and cessation of proton pump inhibitors (PPIs) normalized. Because no study has directly assessed the impact of antisecretory agents on gallbladder function, this study measured gallbladder… Read more »

Barrett’s esophagus and medications that relax the lower esophageal sphincter

OBJECTIVES: Medications that may increase gastroesophageal reflux could be risk factors for esophageal adenocarcinoma; however, epidemiologic studies present conflicting results. We evaluated patients with a high-risk condition, Barrett’s esophagus, to identify risk factors that may act early in the carcinogenic process. METHODS: We conducted a nested case-control study within a large integrated health-services organization. Electronic… Read more »
