Systematic Review of the Risk of Enteric Infection in Patients Taking Acid Suppression

CONTEXT: Proton pump inhibitors (PPIs) and H(2) receptor antagonists (H(2)RAs) have become the mainstay of therapy in acid-related upper gastrointestinal disorders. There have been concerns raised about the possible association of PPIs with enteric infections. OBJECTIVE: We conducted a systematic review to evaluate any association between acid suppression and enteric infection. We also assessed differences between types of enteric infections and the type of acid suppression. DATA SOURCES: Electronic searches of MEDLINE (1966-2005), EMBASE (1988-2005), and CINAHL (1982-2005) were undertaken using a combination of subject headings and text words related to PPI therapy, H(2)RAs, and enteric infections.
