İdiyopatik ani sensörinöral işitme kaybında anti-ısı-şok protein 70 ve paraoksonaz serum düzeylerinin prognostik değeri

Amaç: Bu çalışmada serum anti-ısı-şok protein 70 anti-IŞP 70 düzeyleri ve serum paraoksonaz PON düzeyleri ve idiyopatik ani sensörinöral işitme kaybı İASNİK prognozu arasındaki ilişki araştırıldı.Hastalar ve Yöntemler: Çalışmaya 25 İASNİK’li hasta çalışma grubu olarak ve 25 sağlıklı gönüllü kontrol grubu olarak dahil edildi. Tüm hastalardan tedaviye başlamadan önce ve yalnızca çalışma grubundaki hastalardan tedavinin 10. gününde kan örneği alındı. İdiyopatik ani sensörinöral işitme kaybı, 250-6.000 Hz arasındaki işitme kaybı olarak tanımlandı. Tedavinin 10. gününde işitmede düzelme olup olmadığı değerlendirildi.Bulgular: Tedavi öncesi serum PON ve anti-IŞP 70 düzeyleri tedavi sonrası serum PON ve anti-IŞP 70 düzeyleri ile karşılaştırıldığında, iyileşen hastalarda tedavi sonrası serum PON düzeylerinin arttığı, yine iyileşen hastalarda tedavi sonrası anti-IŞP 70 serum düzeylerinin ise azaldığı belirlendi.Sonuç: Anti-IŞP 70 ve PON serum düzeylerinin, İASNİK’li hastalarda prognozu tahmin etmede ve değerlendirmede kullanılabileceğini düşünmekteyiz

Prognostic value of serum anti-heat-shock protein 70 and paraoxonase levels in idiopathic sudden sensorineural hearing loss

Objectives: This study aims to investigate the correlation between serum anti-heat-shock protein 70 anti-HSP 70 levels, serum paraoxonase PON levels and prognosis of idiopathic sudden sensorineural hearing loss ISSHL . Patients and Methods: Twenty-five patients with ISSHL as the study group and 25 healthy volunteers as the control group were enrolled in this study. Blood samples were obtained from all patients before the treatment initiation and on the 10th day of the treatment from only patients of the study group. Idiopathic sudden sensorineural hearing loss was defined as the hearing loss between 250-6.000 Hz frequencies. The recoveries in the hearing thresholds were evaluated at 10 days of the treatment. Results: When the pre-treatment serum PON, anti-HSP 70 levels and the post-treatment serum PON, anti-HSP 70 levels of the patients with ISSHL were compared, we observed that the post-treatment serum PON levels of the recovered patients increased, while the post-treatment serum anti-HSP 70 levels of recovered patients decreased. Conclusion: We believe that serum levels of anti-HSP 70 and PON can be used as markers for estimating and evaluating the prognosis of ISSHL patients.
