[Dysphagia] PPIs

[eripley at yahoo.com (Irene Campbell-Taylor)]

The longterm use of PPIs has been of concern to many of us for some time givemn that the chronic alteration of pH in the stomach would seem potentially to cause problems.. They have already been implicated in community acquired pneumonia in the elderly and now in bone problems with increased hip fracture that often leads to hospitalization and concomittant morbidities:

  Long-term Proton Pump Inhibitor Therapy and Risk of Hip Fracture 
  Yu-Xiao Yang, MD, MSCE; James D. Lewis, MD, MSCE; Solomon Epstein, MD; David C. Metz, MD 
  JAMA. 2006;296:2947-2953. 
  Context  Proton pump inhibitors (PPIs) may interfere with calcium absorption through induction of hypochlorhydria but they also may reduce bone resorption through inhibition of osteoclastic vacuolar proton pumps. 
  Objective  To determine the association between PPI therapy and risk of hip fracture. 
  Design, Setting, and Patients  A nested case-control study was conducted using the General Practice Research Database (1987-2003), which contains information on patients in the United Kingdom. The study cohort consisted of users of PPI therapy and nonusers of acid suppression drugs who were older than 50 years. Cases included all patients with an incident hip fracture. Controls were selected using incidence density sampling, matched for sex, index date, year of birth, and both calendar period and duration of up-to-standard follow-up before the index date. For comparison purposes, a similar nested case-control analysis for histamine 2 receptor antagonists was performed. 
  Main Outcome Measure  The risk of hip fractures associated with PPI use. 
  Results  There were 13 556 hip fracture cases and 135 386 controls. The adjusted odds ratio (AOR) for hip fracture associated with more than 1 year of PPI therapy was 1.44 (95% confidence interval [CI], 1.30-1.59). The risk of hip fracture was significantly increased among patients prescribed long-term high-dose PPIs (AOR, 2.65; 95% CI, 1.80-3.90; P<.001). The strength of the association increased with increasing duration of PPI therapy (AOR for 1 year, 1.22 [95% CI, 1.15-1.30]; 2 years, 1.41 [95% CI, 1.28-1.56]; 3 years, 1.54 [95% CI, 1.37-1.73]; and 4 years, 1.59 [95% CI, 1.39-1.80]; P<.001 for all comparisons). 
  Conclusion  Long-term PPI therapy, particularly at high doses, is associated with an increased risk of hip fracture.
