Among people with type 2 diabetes who self-reported regularly using a proton pump inhibitor (PPI), the incidence of cardiovascular disease (CVD) events as well as all-cause death was significantly increased in a study of more than 19,000 people with type 2 diabetes in a prospective U.K. database.
During median follow-up of about 11 years, regular use of a PPI by people with type 2 diabetes was significantly linked with a 27% relative increase in the incidence of coronary artery disease, compared with nonuse of a PPI, after full adjustment for potential confounding variables.
The results also show PPI use was significantly linked after full adjustment with a 34% relative increase in MI, a 35% relative increase in heart failure, and a 30% relative increase in all-cause death, say a team of Chinese researchers in a recent report in the Journal of Clinical Endocrinology and Metabolism.
PPIs are a medication class widely used in both over-the-counter and prescription formulations to reduce acid production in the stomach and to treat gastroesophageal reflux disease and other acid-related disorders. The PPI class includes such widely used agents as esomeprazole (Nexium), lansoprazole (Prevacid), and omeprazole (Prilosec).
The analyses in this report, which used data collected in the UK Biobank, are “rigorous,” and the findings of “a modest elevation of CVD risk are consistent with a growing number of observational studies in populations with and without diabetes,” commented Mary R. Rooney, PhD, an epidemiologist at Johns Hopkins University, Baltimore, who focuses on diabetes and cardiovascular diseases.
Prior observational reports
For example, a report from a prospective, observational study of more than 4300 U.S. residents published in 2021 that Dr. Rooney coauthored documented that cumulative PPI exposure for more than 5 years was significantly linked with a twofold increase in the rate of CVD events, compared with people who did not use a PPI. (This analysis did not examine a possible effect of diabetes status.)
And in a separate prospective, observational study of more than 1,000 Australians with type 2 diabetes, initiation of PPI treatment was significantly linked with a 3.6-fold increased incidence of CVD events, compared with PPI nonuse.
However, Dr. Rooney cautioned that the role of PPI use in raising CVD events “is still an unresolved question. It is too soon to tell if PPI use in people with diabetes should trigger additional caution.” Findings are needed from prospective, randomized trials to determine more definitively whether PPIs play a causal role in the incidence of CVD events, she said in an interview.
U.S. practice often results in unwarranted prolongation of PPI treatment, said the authors of an editorial that accompanied the 2021 report by Dr. Rooney and coauthors.
Long-term PPI use threatens harm
“The practice of initiating stress ulcer prophylaxis [by administering a PPI] in critical care is common,” wrote the authors of the 2021 editorial, Nitin Malik, MD, and William S. Weintraub, MD. “Although it is data driven and well intentioned, the possibility of causing harm – if it is continued on a long-term basis after resolution of the acute illness – is palpable.”
The new analyses using UK Biobank data included 19,229 adults with type 2 diabetes and no preexisting coronary artery disease, MI, heart failure, or stroke. The cohort included 15,954 people (83%) who did not report using a PPI and 3,275 who currently used PPIs regularly. Study limitations include self-report as the only verification of PPI use and lack of information on type of PPI, dose size, or use duration.
The findings remained consistent in several sensitivity analyses, including a propensity score–matched analysis and after further adjustment for use of histamine2 receptor antagonists, a drug class with indications similar to those for PPIs.
The authors of the report speculated that mechanisms that might link PPI use and increased CVD and mortality risk could include changes to the gut microbiota and possible interactions between PPIs and antiplatelet agents.
The study received no commercial funding. The authors and Dr. Rooney disclosed no relevant financial relationships.
