The other finding of the study was lower fT3 levels than healthy controls, which has been supported by other studies.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objective: Non-thyroidal illness syndrome (NTIS) can be induced by chronic obstructive airway disease (COPD) exacerbation.

Abstract

Objective: Non-thyroidal illness syndrome (NTIS) can be induced by chronic obstructive airway disease (COPD) exacerbation. The aim of this study was to evaluate the thyroid function impairments and the presence of thyroid antibodies in exacerbated COPD patients and to demonstrate the probable relationship with other clinical and biochemical parameters, such as the parameters of arterial blood gases, urea, creatinine, prothrombine time (PT), activated partial prothrombine time (APTT), and international normalized ratio (INR), etc. Methods: We evaluated 21 patients within the exacerbation period of COPD who had undergone non-invasive mechanical ventilation and had measurements of serum fT3, fT4, and TSH levels and other laboratory tests (glucose, urea, creatinine, hematocrits, hemoglobin, PT, APTT) made on their first to third day of stay in the hospital. Ten of 21 patients had measurements of anti-Tg (antithyroglobulin) antibody and anti-TPO (antithyroperoxidase). The healthy control group consisted of 17 age-matched non-smoking voluntary men admitted to the internal medicine outpatient clinic for general check-up purposes without any complaints or diagnoses. Analyses were made with SPSS 17.0. Results: We found that 33.33% of the patients with COPD exacerbation had fT3 levels below the normal values, and 14.28% of the patients had TSH levels below the normal values. The average fT3 and TSH levels were lower in the patients with COPD exacerbation compared to the healthy volunteers, and fT4 levels were higher in patients compared to the healthy group (patient group mean±SD (median): fT3 2.52±0.48 (2.69), fT4 0.99±0.16 (1.01), TSH 0.95±0.7 (0.80), p=0.001, p=0.001, p=0.009, respectively). Prothrombin time was negatively correlated with fT3 (rs= -0.520, p=0.03). Conclusion: Negative correlation of pH with platelet counts and fT3 with prothrombin time were the novel findings of this study. This study is the first one to determine the relationship with thyroid hormones and coagulation in COPD patients. The other finding of the study was lower fT3 levels than healthy controls, which has been supported by other studies.

Özet

Amaç: Tiroid dışı hastalık sendromu kronik obstriktif akciğer hastalığı (KOAH) atağında tetiklenebilir. Çalışmamızda KOAH atağında olan hastalarda tiroid fonksiyon bozukluklarını ve tiroid antikorlarının varlığını ve diğer klinik ve arter kan gazı, üre, kreatinin, international normalized ratio (INR) vb. parametrelerle ilişkilerini değerlendirmeyi amaçladık. Yöntemler: KOAH atağının 1-3. günlerinde non-invaziv mekanik ventilasyon uygulanan 21 olgu (17 erkek/4 kadın) çalışmaya alındı. Olguların tümünün free T3, fT4, TSH düzeyleri, glikoz, üre, kreatin, hematokrit, hemoglobin, protrombin zamanı (PT), aktive parsiyel tromboplastin zamanı (APTT) parametreleri, 10 olgunun tiroid antikorları değerlendirildi. Dahiliye polikliniğine sağlık kontrolü amaçlı başvuran 17 sağlıklı, sigara içmeyenlerden kontrol grubu oluşturuldu ve benzer parametreleri değerlendirildi. Analizler SPSS 17,0 istatistik programında yapılmıştır. Bulgular: KOAH'lı olguların yaş ortalaması 5,95±10,63, vücut kitle indeksi 23,19±5,8 kg/m2 (n=21), sağlıklı olguların yaş ortalaması 54,35±7,33 kg/m2, vücut kitle indeksi 26,94±5,3 (n=17). Ortalama fT3, TSH düzeyi KOAH'lı olgularda sağlıklı kontrol grubuna göre daha düşüktü, fT4 ise daha yüksekti (hasta grup ort±SD (median); fT3 2,52±0,48 (2,69), fT4 0,99±0,16 (1,01), TSH 0,95±0,7 (0,80). Free T3, KOAH ataktaki olguların %33,33'ünde düşüktü, TSH ise %14,28 olguda normal değerlerin altındaydı (sırasıyla, p=0,001, p=0,001, p=0,009). Protrombin zamanı fT3 ile negatif olarak koreleydi (rs= -0,520, p=0,03). Sonuç: Protrombin zamanı ile free T3 düzeyleri arasındaki negatif korelasyon bu çalışmada saptanan yeni bir bulgudur. Sağlıklı olgulara göre KOAH atakta saptanan daha düşük fT3 düzeyleri diğer çalışmalarla da desteklenmektedir.
