Respiratory Syncytial Virus Vaccine Induced Thrombotic Microangiopathy.

Abstract

Microangiopathic hemolytic anemia with associated multiorgan failure is a medical emergency. The differential diagnosis for microangiopathic hemolytic anemia is broad and requires a systematic, focused approach at ruling out serious causes. However, with the rise of new vaccines and sporadic reports of vaccine-induced microangiopathic hemolytic anemia, it is essential for providers to include vaccines as a potential cause on their differential diagnosis. Here, we report the first case of respiratory syncytial virus vaccine-induced microangiopathic hemolytic anemia, anuric renal failure, and metabolic encephalopathy in the world.
