Abstract
An unusual reaction associated with chronic low-dose cytarabine is described. A 77-year-old man complained of three to four weeks of hearing loss and progressive inability to walk without assistance. He had received two courses of cytarabine 100 mg sc/wk for the management of myelofibrosis myeloid metaplasia over 21 months. He received a total of 3 g over seven months during his first course followed ten months later with 1.2 g over four months. Conjunctivitis was also identified on physical examination at the time of his admission. He was admitted to the neurology service where a complete neurological work-up with consultations from the ophthalmology, audiology, hematology, and ear, nose, and throat services failed to identify a cause of his symptoms. Cytarabine was discontinued on the suspicion that his symptoms were drug induced. The conjunctivitis resolved completely with ophthalmic antibiotics and corticosteroids. His hearing slowly improved over three to four weeks, and he was able to ambulate with a walker. He continued to improve at home although some hearing loss remained three months after his initial presentation. Although conjunctivitis and neurotoxicity are well-known complications of high-dose cytarabine, there are no prior reports of these reactions after low-dose therapy. Hearing loss, which has not been previously reported with cytarabine alone, appears to be a new complication of cytarabine administration.Keywords
