More and More data is ganging up on Proton pump inhibitors

The story of PPIs apparently interfering with the beneficial effect of Plavix is widely distributed and read. Now we see data (see here for abstract) that links spontaneous bacterial peritonitis (SBP) in advanced cirrhosis with PPI use. This was a case control study with an OR of 4.3,so I cannot make my typical whinny remark about the appropriate level of concern with relative risks of less than 2.

PPIs seem to be the mirror image of statins which have an increasing number of studies indicating a new benefit.With regard to PPIs, we may have to worry more and more about bad effects including: pneumonia ( see here for a rather unconvincing study), fractures ( see here), heart attacks ( see here for a good review of the Plavix-PPIs issue by Dr. Richard Fogoros) and now SBP. I would not be surprised if H2 blocker sales may have an uptick.
