Shoshin beriberi in an AIDS patient with end-stage renal disease.

Asymptomatic cardiomegaly and subsequent fulminant pulmonary edema developed in an AIDS patient with end-stage renal disease who had no prior history of cardiac disease. Intravenous thiamine administration led to dramatic resolution of both obtundation and cardiovascular collapse within 4 hours. Prolonged thiamine administration led to decreased cardiomegaly. These findings are consistent with Shoshin beriberi.
