title: Renal cortical infarction following treatment with sumatriptan in a kidney allograft recipient.
abstract: Renal cortical infarction is a rare cause of acute kidney injury that results from inadequate blood flow to the kidney, most commonly as a consequence of thrombotic or embolic occlusion of the renal artery or profound hypoperfusion. We report the case of a 78-year-old female kidney transplant recipient who developed a migraine headache, took sumatriptan, and soon after developed pain over the allograft and oligoanuric acute kidney injury. Kidney allograft biopsy showed renal cortical infarction. The mechanism of action of sumatriptan involves vasoconstriction, which counters the vasodilatation that is central to the pathogenesis of migraines. This case raises important questions regarding the safety of triptans with calcineurin inhibitors (which also act to vasoconstrict), particularly in elderly patients.
