Acute transient sensorineural hearing loss due to Anaplasma phagocytophilum.
We report the case of a patient who presented with a 3-month history of random epistaxis and recent onset of acute hearing loss associated with fever, chills, and myalgias. Pure tone audiometry revealed bilateral sensorineural hearing loss. Complete blood cell count showed an abnormal neutrophil count of 700/uL (normal >1900/microL) and platelet count of 25 x 10(3)/microL (normal >175 x 10(3)/microL). Giemsa-stained peripheral blood smear revealed neutrophilic intracytoplasmic inclusion consistent with anaplasma morulae. Polymerase chain reaction confirmed Anaplasma phagocytophilum. The patient was treated with oral doxycycline, and, after 14 days of treatment, the hearing loss had improved markedly. Therefore, we concluded that the patient's acute transient bilateral sensorineural hearing loss was associated with anaplasmosis.
