Fanconi syndrome induced by red yeast rice supplement.

Fanconi syndrome is a disorder of the proximal renal tubules characterized by metabolic acidosis, renal glycosuria, and aminoaciduria. Recently, Fanconi syndrome caused by red yeast rice supplements has been reported. We encountered a 60-year-old woman with acute kidney injury and Fanconi syndrome caused by a red yeast rice supplement. The patient discontinued the supplements, leading to an improvement in her serum creatinine and urinary protein levels. Early detection and discontinuation of the suspected drugs are important for the treatment of drug-induced Fanconi syndrome.
