A 51-year-old man, homosexual, recently diagnosed with ocular neurosyphilis, presented to the emergency room with a 1-day history of fevers and chills. His vital signs were significant for a temperature of 102.8°F and tachycardia of 125 bpm. The patient had experienced blurred vision in his left eye and was diagnosed with ocular neurosyphilis 10 days prior to the current presentation. He was treated with a 14-day course of high-dose intravenous penicillin and oral prednisone. His laboratory studies were significant for transaminitis, with an aspartate aminotransferase of 1826 U/L, alanine aminotransferase of 1743 U/L, total bilirubin of 1.2 mg/dL and alkaline phosphatase of 68 U/L. After ruling out viral aetiologies and toxin-induced hepatic injury, penicillin was discontinued on the day following admission and transaminases promptly improved with resolution of symptoms. The patient's vision returned to normal within 2 weeks after discharge from hospital.
