A population-based study in Canada revealed that older adults who started proton pump inhibitors (PPIs) therapy had an increased risk of acute kidney injury and acute interstitial nephritis. The study included 290 592 individuals 66 years and older who initiated PPI therapy between Apr. 1, 2002, and Nov. 30, 2011. Propensity score matching were used to establish an equal number of highly comparable reference group of control patients. The primary outcome was hospital admission with acute kidney injury within 120 days, and a secondary analysis examined acute interstitial nephritis. The rates of acute kidney injury (13.49 v. 5.46 per 1000 person-years, respectively) and acute interstitial nephritis (0.32 vs. 0.11 per 1000 person-years) were higher among patients given PPIs than among controls. A growing body of literature suggests that PPIs use increase the risk of osteoporosis, acute interstitial nephritis and a risk that people won’t absorb certain vitamins and minerals such as magnesium, iron, B12 and calcium.
