Sensorineural dysacusis in patients with systemic lupus erythematosus

Abstract

The objective of this study was to establish the frequency of involvement of the auditory apparatus in 45 female patients with systemic lupus erythematosus (SLE) submitted to general clinical and laboratory assessments, and tone and vocal audiometry accompanied by a questionnaire evaluating auditory symptoms. The control group consisted of 45 healthy women, matched by age. Auditory symptoms were present in 25 (55.5%) patients, with a diagnosis of sensorineural hearing loss in seven (15.6%) patients. A significant correlation with hypoacusis (P < 0.001), ear fullness (P = 0.012) and tinnitus (P = 0.017) was observed in patients with hearing loss. None of the clinical or laboratory parameters showed an association with sensorineural hearing loss. In the control group, three women (6.7%) presented audiometric alterations, including two with altered tympanometry results and one with mild sensorineural hearing loss. In conclusion, an adequate investigation of auditory symptoms is important during the follow-up of patients with SLE, since manifestations of the auditory apparatus and sensorineural hearing loss can affect a significant proportion of patients.
