Abstract:
Selective androgen receptor modulators (SARMs) are novel nonsteroidal agents abused for performance enhancement such as anabolic steroids. We report a case of a 27-year-old man who used 3 different SARMs and presented with progressive weakness. Initial laboratory testing showed kidney and liver injury with creatinine 4.8 mg/dL and total bilirubin 43.3 mg/dL. An extensive workup was negative for other causes, and the results of liver and kidney biopsies were consistent with bile cast nephropathy because of SARM-associated drug-induced liver injury. His organ functions improved with the cessation of SARMs and plasmapheresis. Providers need to recognize the extreme consequences of SARM use.
