How a longstanding P & T Committee identifies and meets current therapeutic challenges.

The P & T Committee at the University of Michigan, Ann Arbor, has run smoothly for some time. Nevertheless, it is not immune to today's fiscal and drug therapy challenges. In this exclusive Hospital Formulary interview, Dr. Jeoffrey Stross, chairman; Dr. Richard deLeon, secretary; and Dr. Burgunda Volger, a key University Hospital P & T Committee member, candidly describe their committee's philosophy and the mechanics by which it functions. This committee uses restriction to modify inappropriate prescribing, but it also carries out educational activities. As newer, more expensive, therapies become available, the responsibility to ensure efficacious, safe, economical therapy becomes increasingly complex. The following discussion highlights some of their strategies for success.

Ibuprofen-associated renal dysfunction. Pathophysiologic mechanisms of acute renal failure, hyperkalemia, tubular necrosis, and proteinuria.

Ibuprofen-associated, acute, reversible renal failure with hyperkalemia, tubular necrosis, and proteinuria developed in a patient who had no predisposing underlying disease. A renal biopsy specimen revealed mesangial hypercellularity without glomerular crescent formation. A profound interstitial nephritis with focal inflammatory cell infiltrates of predominantly mononuclear cells and neutrophils as well as focal tubular destruction was seen. Vasculitis was not observed. Ultrastructural studies confirmed the light microscopic diagnosis of a tubulointerstitial nephritis and, in addition, indicated the presence of electron-dense mesangial and subepithelial deposits. Direct immunofluorescence examination showed diffuse mesangial IgM and C3 deposition as well as vascular C3 deposition. Renal failure rapidly resolved after discontinuation of ibuprofen therapy and initiation of steroid therapy, with return to normal levels of serum creatinine, urea nitrogen, potassium, and sodium. Proteinuria also resolved.
