Abstract

Objective: This study aims to investigate long-term effects of iodinated radiographic contrast media used for coronary angiography (CAG) on the thyroid function in euthyroid patients. Methods: In a prospective observational cohort study, nonionic iodinated contrast material was electively used in 101 patients for coronary angiography. The patients were recruited without age restrictions and, at baseline, all had normal levels of free triiodothyronine (FT3), free thyroxine (FT4) and thyrotropin (TSH). The morphology of the thyroid was evaluated by thyroid ultrasonography (USG). Four and eight weeks after CAG, serum TSH, FT3 and FT4 levels were assessed. Results: Compared to a mean baseline level of 1.49 (25%-75%, range 13-2.21), follow-up TSH levels decreased significantly to 1.45 (25%-75%, range 1.98-0.92, p=0.017) and 1.40 (25%-75%, range 1.89-0.87, p=0.003) at 4 weeks and 8 weeks, respectively (p=0.008). No significant diffe-rence was observed in TSH levels between the 4th and 8th weeks (p=0.833). Conclusion: Iodinated radiographic contrast agents may cause subclinical hyperthyroidism in euthyroid patients undergoing CAG.

Özet

Amaç: Bu çalışma ötiroid hastalarda koroner anjiyografi için kullanılan radyolojik iyotlu kontrast maddelerin uzun dönemde tiroid fonksiyon- larına etkisini araştırmak amacıyla yapıldı. Yöntemler: Elektif şartlarda koroner anjiyografi amacıyla noniyonik iyotlu kontrast madde kullanılan 101 hastada prospektif gözlemsel kohort çalışması yapıldı. Çalışmaya alınan tüm hastaların serbest triiodotironin (sT3), serbest tiroxin (sT4), bazal tirotropin (TSH) değerleri normaldi ve yaş sınırlaması yapılmadı. Tiroid ultrasonografi (USG) yapılarak tiroid morfolojisi değerlendirildi. KAG işleminden 4 hafta ve 8 hafta sonra hastaların serum TSH, sT3, sT4 değerleri kontrol edildi. Bulgular: TSH bazalda 1.49 (%25-%75;13-2.21); 4.haftada 1.45 (%25-%75; 0.92-1.98) ve 8.haftada 1.40 (%25-%75; 0.87-1.89) olarak saptanmış olup; takipler arası değişim istatistiksel olarak anlamlı bulunmuştur (p=0.008). Bazal TSH düzeylerine göre 4. haftada (p=0.017) ve 8. haftada (p=0.003) istatistiksel olarak anlamlı düşüşler gözlenirken; 4. hafta ile 8. hafta TSH düzeyleri arasında anlamlı değişim gözlenmedi (p=0.833). Sonuç: Ötiroid hastalarda koroner anjiyografi amacıyla iyotlu radyolojik kontrast maddelerin kullanılması subklinik hipertiroidizme neden olabilir.
