A study of auditory evoked potentials in systemic lupus erythematosus patients.
Systemic lupus erythematosus (SLE) is a multifactorial chronic systemic inflammatory disease, of unknown origin, characterized by the presence of autoantibodies and polymorphic clinical manifestations. This disease may involve multiple organs and systems. The most common findings are articular, cutaneous, vascular, renal, neurological, cardiac, gastrointestinal, hematological, ocular, and auditory abnormalities.


OBJECTIVE
To investigate the central auditory function of subjects diagnosed with Systemic Lupus Erythematosus (SLE).


METHODS
A time-series study was made of sixty subjects, aged between 21 and 46 years, which were divided into a control (n=30) and an experimental group (n=30). A clinical history, audiological evaluation (pure tone audiometry, speech audiometry and immitance testing) and short (ABR), middle (MLR) and long latency (LLAEP) potentials were carried out in all subjects.


RESULTS
No statistically significant differences were observed between the groups in any of the evaluations.


CONCLUSIONS
In this study there were no differences in short, middle and long latency auditory potentials between the control and experiment subject groups.
