Abstract
Dobutamine is a weak beta-1 and a potent beta-2 adrenergic agonist commonly used to treat patients in cardiogenic shock. It enhances myocardial contractibility, increasing cardiac output. Myoclonus in patients receiving an infusion of dobutamine is rare and, although not fully understood, seems more common in patients with severe kidney failure. To our knowledge, this is the first reported case of dobutamine-induced myoclonus in a patient with kidney failure receiving peritoneal dialysis. Only 7% of the 518,749 patients of the United States requiring kidney replacement therapy receive peritoneal dialysis, with only a small unknown number of those with advanced heart failure manage with an infusion of inotropic medication. The low prevalence of combined advanced heart failure and kidney failure could partly explain this condition’s rarity. In this study, we report the case of a 64-year-old woman with kidney failure receiving peritoneal dialysis in whom myoclonus developed 3 weeks after starting a dobutamine infusion for advanced refractory heart failure. Infectious and other pharmacologic causes of myoclonus were ruled out. Initially, uremia was suspected; however, despite increasing her peritoneal dialysis dose, it was only after discontinuing the dobutamine infusion that her myoclonus resolved.
