Epidemiologia de perda auditiva em doentes renais crônicos na atenção secundária prevalência e fatores associados

Abstract

INTRODUCTION: Hearing loss is an increasingly condition seen in the population. It is found with greater frequency in some specific groups such as elderly people, people with systemic arterial hypertension and diabetes mellitus. Evidence suggests increased prevalence of hearing loss in patients with chronic kidney disease (CKD), however studies in the brazilian population with CKD are scarce. OBJECTIVES: The aim of our study was to evaluate the prevalence of hearing loss in a population of patients with non dyalitic chronic kidney disease and associated factors. METHODOLOGY: We used a convenience sample of patients with CKD (n = 159), aged 18 to 65 years. The auditory acuity was assessed by pure-tone audiometry threshold and by the questionnaire WHO Ear and Hearing Disorders Survey Protocol for a Population-Based Survey of Prevalence and Causes of Deafness and Hearing Impairment and other Ear Diseases translated and validated into Portuguese. We collected demographic and clinical data, also carried out otoscopy, and dosage of biochemical markers and inflammatory cytokines TNF-α ,IFN-γ, IL-1β, IL-6,IL-10 ,IL-17 . RESULTS: In the analyses we checked the prevalence of 25,16% of hearing loss among the participants. In our study we did not find any association between the progression of the stages of CKD and the increase of the prevalence of hearing impairment, nor with its severity. The blood markers analyses were not able to establish a correlation between the progression of stage of chronic kidney disease and hearing loss. CONCLUSIONS: The prevalence of hearing loss was 25,16% in the studied population. It is recommended that strategies be implemented for the prevention and reversal of this situation in this target group.
