TİROTOKSİKOZUN SOLUNUM FONKSİYONLARI ÜZERİNDEKİ ETKİLERİ

Year 2002, Volume: 16 Issue: 1, 0 - 0, 01.05.2002

Abstract

Tirotoksikoz, tiroid hormonlarındaki artış sonucu metabolik hızın artmasına bağlı olarak kardiyak ve pulmoner sistemleri büyük ölçüde etkileyen bir klinik tablodur. Bu çalışmanın amacı tirotoksikozun pulmoner sistem üzerindeki etkilerini araştırmaktır. Ocak-Aralık 2001 tarihleri arasında İzmir Atatürk Eğitim ve Araştırma Hastanesi Endokrinoloji polikliniğine başvuran hipertiroidi tanısı alan 40 olgunun solunum sayıları, solunum fonksiyon testi (SFT) ve kan gazı parametreleri incelendi. Ayrıca bu üç parametre kontrol grubu olarak İzmir Göğüs hastalıkları ve Cerrahisi Eğitim Hastanesi polikliniğine nonspesifik semptomlarla başvuran 45 olguda da ölçüldü. Hipertiroidi grubundan, antitiroidal tedavi sonrası ötiroid olan 5 olgunun tüm ölçümleri tekrarlandı. Solunum sayısı hipertiroidi grubunda kontrol grubuna göre anlamlı olarak yüksek bulundu( sırasıyla 21.70±3.61/dak ve 16.31±1.90/dak p = 0.000 ). Kan gazı parametrelerinden PaO2 ve PaCO2 hipertiroidi grubunda daha düşük olmakla birlikte fark istatistiksel olarak anlamlı değildi. SFT parametrelerinden FEV1 ve FVC değerlerinin hipertiroidi grubunda anlamlı olarak düşük olduğu saptanırken, FEV1/FVC oranı iki grupta da normal sınırlarda bulundu ve her iki grup arasında anlamlı fark saptanmadı ( sırasıyla p = 0.012, p = 0.005, p=0.102). Antitiroidal tedavi sonrası ötiroid olan 5 olguda FEV1, FVC, PaCO2 değerlerinde ve solunum sayısında istatistiksel olarak anlamlı düzelmeler saptandı. Sonuç olarak tirotoksikozun pulmoner sistemde gaz alışverişini etkilemediği, solunum sayısını arttırdığı, ayrıca düşük FEV1 ve FVC değerlerine rağmen FEV1/FVC oranının normal sınırlarda bulunması nedeni ile restriktif tipte bir solunum fonksiyon bozukluğu oluşturduğu sonucuna varıldı.

THE EFFECTS OF THYROTOXICOSIS ON PULMONARY FUNCTIONS

Year 2002, Volume: 16 Issue: 1, 0 - 0, 01.05.2002

Abstract

Thyrotoxicosis is a clinical picture which largely affects cardiac and pulmonary systems owing to increase in metabolic rate due to increase in thyroid hormones. The aim of this study was to examine the effect of thyrotoxicosis on pulmonary system. Arterial blood gases, pulmonary function tests and respiration rates of 40 cases who admited to endocrinology department in Izmir Atatürk Training Hospital and diagnosed with hyperthyroidism between January and December 2001 were examined. Also these three parameters were applied to 45 control cases who admited to outpatient clinic of Izmir Chest Diseases and Surgery Training Hospital with nonspesific symptoms. The measurements of 5 cases with hyperthyroidism were repeated after they became euthyroid with an antithyroid therapy. Respiration rate was found to be significantly higher in cases with hyperthyroidism than the ones in the control group ( respectively 21.70±3.61/min. and 16.31±1.90/min p = 0.000 ). In cases with hyperthyroidism the PaO2 and PaCO2 values were lower but this difference was not statistically significant. In hyperthyroid cases while FEV1 and FVC levels were significantly lower , FEV1/FVC ratio was found to be normal in both groups and no significant difference was found ( respectively p = 0.012, p = 0.005, p=0.102 ). FEV1, FVC, PaCO2 and respiration rate values were significantly improved in five patients who became euthyroid after antithyroid therapy. These data suggest that thyrotoxicosis does not affect gase exchange in pulmonary system, increase respiration rate and owing to low FEV1, FVC values and normal FEV1/FVC ratio, it causes a restrictive pattern in pulmonary functional tests.
