Description
Summary:The aim of this paper is to describe the auditory profile of subjects who were given streptomycin treatment for tuberculosis in the years 2000 and 2001, in Recife, Northeast Brazil. The Injury Notification Database at the Municipal Department of Health was consulted and 78 individuals who had been on streptomycin during the period under study were selected. Forty-two individuals were excluded, of whom five were over 59 years of age and two were under 18 years. Nineteen turned out to be deceased, 13 could not be found, two were serving prison terms and one refused to participate. As a result, only 36 subjects participated in the study. These 36 individuals were interviewed and underwent meatoscopy and audiometry. The mean age of the group under study was 38.8 years old and males predominated (79.4%). Twenty-seven patients (75%) showed hearing impairment, the bilateral sensorineural type (63.9%) being the most frequent, mainly affecting the high frequencies over 4000 Hz. In the light of findings showing a high percentage of hearing impairment complaints among users of streptomycin, this issue seems to warrant an in-depth investigation, as does the implementation of an auditory follow-up routine for patients undergoing such chemotherapy for tuberculosis.<br>Este trabalho teve por objetivo descrever o perfil auditivo de pessoas que realizaram tratamento para tuberculose com estreptomicina em Recife nos anos de 2000 e 2001. Para tal foi utilizado o banco de dados do Sistema de Informação de Agravos de Notificação, fornecido pela Secretária de Saúde deste município, sendo selecionadas 78 pessoas que usaram a droga no período em estudo. Do total de pacientes selecionados sete eram menores de 18 anos ou maiores de 58 anos, 19 haviam falecido, 13 não foram localizados, dois eram presidiários, um negou-se a participar, restando, pois 36 indivíduos que puderam ser submetidos a uma entrevista, a meatoscopia e a audiometria. No grupo estudado predominou o sexo masculino (79,4%) e a média das idades era de 38,8 anos. Dos 36 pacientes, 27 (75,0%) apresentaram alteração auditiva, sendo a mais freqüente a sensório-neural bilateral (63,9%), com predomínio de freqüências agudas, a partir de 4000 Hz. Os achados com elevados percentuais de alteração auditiva entre os usuários de estreptomicina, apontam para a necessidade de aprofundamento deste tema em outros estudos, e também sugerem a necessidade de estruturação de um sistema de monitoramento auditivo para a população de pacientes submetidos a esse quimioterápico no tratamento para tuberculose.
