    ABSTRACT: OBJECTIVES: The objectives of this study were to assess characteristics of hearing impairment (HI) in Mexican Mestizo patients with rheumatoid arthritis. METHODS: One hundred thirteen consecutive patients (101 women, aged 43.3 ± 13.1 years) without previously identified HI diagnosis had a structured interview and complete rheumatic and audiologic evaluations, which included at least a pure-tone audiometry and standard and high-frequency tympanometry. Hearing impairment was defined if the average thresholds for at least 1 of low-, mid-, or high-frequency ranges were 25-dB hearing level or greater in 1 ear (unilateral) or both ears (bilateral). Hearing impairment was classified as mild or moderate/severe. Appropriate statistics, multivariate analysis, and receiver operating characteristic curves were used. RESULTS: Hearing impairment was detected in 27 patients (24%), was sensorineural-type HI in 25 (93%), bilateral in 14 (52%), and mild in 20 of them (74%). Normal tympanograms (type A) were found in 93 patients (82%), although high-frequency tympanometry was abnormal in 80 patients (71.4%). Patients with HI were significantly older (51.8 ± 14.1 vs. 40.7 ± 11.7 years, P ≤ 0.001), had more frequent rheumatoid nodules (37% vs. 12.8%, P = 0.001), and had more (median [range]) comorbidities per patient (2 [1-2] vs. 1 [0-2], P = 0.03). Multivariate analysis showed that HI was significantly associated to age (odds ratio, 1.1; 95% confidence interval, 1.03-1.15; P ≤ 0.001). The best cutoff level for HI was 50 years of age and increased to 59 years for moderate/severe HI. CONCLUSIONS: A significant proportion of Mexican Mestizo outpatients with rheumatoid arthritis had previously undiagnosed HI, mainly of sensorineural type, of mild severity, and bilateral. Older age was the only prognosticator of HI.

    ABSTRACT: To evaluate the prevalence and potential associations of hearing impairment in patients 30 to 50 years old with diabetes diagnosed before age 40 years-early-onset type 2 diabetes mellitus (T2DM). The study cohorts consisted of 46 consecutive patients with early-onset T2DM and 47 age-matched control subjects with rheumatoid arthritis. All study subjects completed clinical, serologic, and auditory assessments. The patients with T2DM had a mean age of 42 ± 6 years and a mean disease duration of 11 ± 6 years. Microalbuminuria was present in 26.1%, proliferative retinopathy in 26.1%, and symptomatic peripheral neuropathy in 23.9%. The prevalence of unilateral or bilateral hearing loss was significantly higher in the patients with T2DM than in the patients with rheumatoid arthritis (21.7% versus 6.4%, respectively; P = .01). Most cases of hearing loss were mild and involved high or acute tones. After multivariate analysis with adjustment for age, there was a significant association between hearing loss and hemoglobin A1c (odds ratio, 1.3; 95% confidence interval, 1.02 to 1.81; P = .035). In the patients with T2DM, the lengthening of the brainstem response was not significantly increased; however, the wave morphologic features were abnormal and the reproducibility was poor in both ears in 11 patients (24%). Patients with early-onset T2DM and poor glycemic control have an increased prevalence of subclinical hearing loss and impaired auditory brainstem responses. Hearing impairment may be an underrecognized complication of diabetes.
