Proton Pump Inhibitors, Associated Complications, and Alternative Therapies: A Shifting Risk Benefit Ratio.

Abstract

Our goal was to compile the most recent and accurate data on the side effects of proton pump inhibitors (PPI). We also compared the efficacy of PPI to the efficacy of different surgical options for acid reflux control. Proton pump inhibitors are the primary therapy for chronic control of gastroesophageal reflux disease (GERD), but newer studies demonstrate deleterious side effects. Collating this information and contrasting it with surgical therapy for GERD provides evidence for possible practice changes in treatment. A literature search utilizing PubMed was performed evaluating for PPI and anti-reflux surgery (ARS), focusing on articles that reflected information regarding the usage and efficacy of symptom control of both PPI and ARS. Search terms included "ARS, fundoplication, MSA, acute interstitial nephritis, acute kidney injury, chronic kidney disease, meta-analysis, PPI, H2 blocker, cardiovascular risk, and gut dysbiosis." We evaluated 271 articles by title, abstract, and data for relevance and included 70. Long-term control of GERD with PPI may have a greater than expected side effect profile than initially thought. Surgical options may provide greater symptom control than PPI without the side effects of long-term medical therapy. Anti-reflux control can be safely achieved with either PPI or surgical options; however, the long-term side effects noted in the review such as increased risk of cardiovascular events, renal disease, and gut dysbiosis may suggest surgical anti-reflux control as a better long-term option.
