PPIs linked to pneumonia
Initiation of proton pump inhibitors within the past month is linked to an increased risk of community-acquired pneumonia, but long-term use is not, an analysis of the UK general practice research database suggests.
A comparison of 80,066 patients with community-acquired pneumonia and 799,881 controls showed a sixfold increase in risk in patients prescribed PPI therapy within the previous two days, an almost fourfold increase with PPI initiation in the previous week and a threefold increase within the previous fortnight.
But there was no increased risk for community-acquired pneumonia overall and no significant association with longer-term PPI use.
