Sensorineural hearing loss in acromegalic patients under treatment.

UNLABELLED: Acromegaly is a rare endocrine disease. Few studies have evaluated its association with hearing loss (HL) and the results are conflicting. AIM: To evaluate the prevalence and features of HL in a group of patients being treated for acromegaly. To analyze peripheral and central auditory transmission. METHODS: Cross-sectional study. A group of 34 patients with acromegaly were submitted to metabolic evaluation, tonal audiometry and brainstem auditory evoked potentials. HL was considered when pure tone average was > 25 DBHL for low frequencies (250, 500, 1000 and 2000 Hz) or high frequencies (3000, 4000, 6000 and 8000 Hz). The patients were divided in group A (with HL) and B (without HL). RESULTS: Twelve patients (35.3%) had sensorineural HL (Group A), being 8 bilateral and 4 unilateral. No one had mixed or conductive HL. The prevalence of diabetes/impaired glucose tolerance was similar between the groups. The frequencies 3000, 4000, 6000 and 8000 Hz were the most affected and with a similar pattern in both ears. CONCLUSION: sensorineural HL was found in 38.9% of cases. Neither clinical nor metabolic differences were noted between the groups, as well as in regards to peripheral and central auditory transmission.

Perda auditiva sensorioneural em pacientes com acromegalia em tratamento / Sensorineural hearing loss in acromegalic patients under treatment

Acromegalia é uma doença endócrina rara. Poucos estudos avaliaram sua associação com deficiência auditiva (DA) e os resultados são conflitantes. OBJETIVOS: Avaliar a prevalência e características da DA em um grupo de pacientes com acromegalia em tratamento. Analisar a transmissão auditiva central e periférica. MATERIAL E MÉTODOS: Estudo transversal. Um grupo de 34 pacientes com acromegalia submeteu-se à avaliação metabólica, audiometria tonal e potenciais evocados auditivos de tronco encefálico (PEATE). Considerou-se DA quando a média dos tons puros foi > 25 DBNA para baixas frequências (250, 500, 1000 e 2000 Hz) ou altas frequências (3000, 4000, 6000 e 8000 Hz). Os pacientes foram divididos em grupo A (com DA) e B (sem DA). RESULTADOS: Doze pacientes (35,3%) mostraram DA sensorioneural (grupo A), sendo oito bilateral e quatro unilateral. Nenhum apresentou DA mista ou condutiva. A prevalência de diabetes/intolerância à glicose de jejum foi similar entre os grupos. As frequências de 3000, 4000, 6000 e 8000 Hz foram as mais afetadas e com padrão similar em ambos os lados. CONCLUSÃO: DA sensorioneural esteve presente em 35,3% dos casos. Não foram notadas diferenças clínicas ou metabólicas significativas entre os grupos, bem como na transmissão neural auditiva periférica e central.
