Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease of immune dysregulation characterized by unchecked inflammatory responses leading to end-organ dysfunction. Primary HLH results from inherited mutations that impair the capacity for immune regulation; secondary HLH arises from the inappropriate response to an immune stimulus, such as infection, malignancy or autoimmunity. What is less well known is…
The diagnosis of rheumatic diseases requires the exclusion of other systemic disorders. Infection, hematologic conditions, malignancies and some drugs may all lead to syndromes that closely mimic rheumatic diseases, which may lead to diagnostic delays. Idiopathic multicentric Castleman disease (iMCD) is a heterogeneous group of lymphoproliferative diseases (LPDs) characterized by systemic inflammatory manifestations.1,2 As with…

I should have paid more attention in medical school. If I had, I might have remembered enough about basic pathophysiology to know why everyone was suddenly pulling their patients off of lisinopril. For those of you who need a quick primer: When the pressure in the renal artery drops, the kidney secretes renin. Working together,…
