To find out the association between rheumatoid factor and hearing loss, a prospective study was conducted at Tertiary care/Medical college hospital. We screened 85 patients with positive rheumatoid factor for evidence of hearing loss. These patients were collected from the Departments of Medicine and Orthopedics. Out of 85 patients, who were positive for rheumatoid factor, underwent screening for hearing loss. These patients had a normal pure tone audiogram but Distortion product otoacoustic emission (DPOAE) was absent in twenty three patients. DPOAE was absent in 27% of cases, in whom there was positive rheumatoid factor. It was extremely statistically significant.
为了探究类风湿因子与听力损失之间的关联，在三级医疗/医学院附属医院进行了一项前瞻性研究。我们筛查了85名类风湿因子呈阳性的患者，以寻找听力损失的证据。这些患者来自内科和骨科。在85名类风湿因子呈阳性的患者中，均接受了听力损失筛查。这些患者的纯音听力图正常，但有23名患者的畸变产物耳声发射（DPOAE）缺失。在类风湿因子呈阳性的病例中，27%存在DPOAE缺失。这在统计学上具有极其显著的意义。
