It began as many cases do: an ill patient, in the ICU, with signs and symptoms across several body systems, yet no clear unifying diagnosis on admission. With things stabilizing, the internal medicine hospital team on which I was serving as hospitalist that week assumed care of the patient. As the case unfolded – pulmonary infiltrates that could be hemorrhagic, renal dysfunction with proteinuria – rheumatic diseases rose in the differential. When serologic studies and other data suggested GPA rather than glomerular basement membrane (GBM) disease or other possibilities such as infection, it seemed the right time to act. And that is when a game of what I call “steroid poker” began.
