Two cases of sensory neural hearing loss as a manifestation of HIV infection

In patients with HIV infection, oral and pharyngeal pathology frequently occurs, but there have been no reports on cases of deafness in Japan. Herein, the authors report two cases of sensory neural hearing loss in hemophilia A patients infected with HIV through factor VIII concentrates.Case 1 was a 16-year-old male with hemophilia A. He had been administered factor VIII concentrates starting at 6 months after birth. At 8 years of age, HIV antibodies were positive. He was diagnosed as having AIDS after suffering from pneumocystis carinii. He complained of right otalgia and slight vertigo during treatment for a relapse of the penumocystis carinii. He underwest otological examinations at our department. The right tympanic membrane showed opacification and serous otorrhea was noted. Acute otitis media was diagnosed and tympanotomy was conducted. Afterwards, the right tympanic membrane developed a large perforation and sensory neural hearing loss occurred.Case 2 was a 49-year-old male with hemophilia A. He had been administered factor VIII concentrates from the age of 23 years. At 48 years of age, HIV antibodies were positive. The patient complained of sudden deafness in the right ear and slight vertigo. He underwest otological examinations at our department. The tympanic membrane was normal bilaterally, but sensory neural hearing loss was found in the right ear.It was presumed that acute otitis media directly involving the inner ear had caused a perceptive disorder in case 1 while a pattern of sudden onset of deafness was apparent in case 2.
