Recurrent herpes zoster ophthalmicus in a young, healthy individual taking high doses of l-Arginine.


ABSTRACT: Purpose:To report a case of a healthy, young male with recurrent herpes zoster ophthalmicus (HZO) and high-dose l-arginine supplementation. Observations:A 39-year-old man presented to another institution with a HZO involving the right eye. He was treated with oral acyclovir with complete resolution. Four months later the patient had a recurrent HZO episode and was started again on oral acyclovir. After resolution of the episode, the patient was continued on 1?g of oral acyclovir daily as a prophylactic measure. He then presented to our institution for a second opinion. The patient was otherwise healthy, with no past medical history involving systemic immunosuppressant agents or HIV. However, the patient was an active weight lifter taking high doses of amino acids. A diet recall was performed prior to both HZO episodes, which calculated an average intake of 46.5?g of l-arginine a day. Examination revealed 20/40 best-corrected acuity, anterior stromal haze in the visual axis, and inferior superficial punctate keratitis in the right eye. The patient was treated for dry eye disease with punctual plugs and artificial tears. The patient was instructed to decrease all supplemental arginine consumption while continuing with oral acyclovir prophylaxis for one year. Conclusions and importance:l-arginine is associated with the replication and virulence of a variety of viruses in vitro, including herpes simplex and varicella zoster. Although arginine consumption increased prior to the initial and recurrent HZO infection, further investigation needs to be performed to deem if a true association exists.
