Abstract
Objective
Covid-19 disease is diagnosed by moleculer, serologic or radiological methods. However, these diagnostic methods cannot be reached everywhere or take too much time to result. So, we need for effective diagnosis of Covid-19 patients with simple and easy accessible laboratory biomarkers. Therefore, we investigated the diagnostic performance of Eosinophilic Cationic Protein (ECP) in Covid-19.
Material and Methods
Our study is a retrospective case-control study. The recorded clinical, laboratory and radiological data of 30 patients who were diagnosed with Covid-19, between 15 March and 15 June 2020, were compared with 30 healthy person by using appropriate statistical methods.
Results
Both patients and conrols included 10 (33.3%) females and 20 (66.6%) males with a mean age of 57.2 ± 15.46 and 60.07 ± 20.59 respectively. Eosinophil counts of the patients at admission were significantly lower than the controls (p <0.001). Eosinophil counts one week after admission were increased significantly compared to the admission levels (p= 0.004). ECP values of the patients one week after admission were significantly lower than controls and decreased compared to the admission (p= 0.023, p= 0.001respectively). ECP values of one week later, differentiated patients and controls with 46.7% sensitivity, 93.3% specificity and a cutoff value of ≤ 88.67 ng/mL. ROC analysis of ECP2; (AUC)= O.740, p= 0.023.
Conclusion
It will be of great benefit in terms of public health that suspected patients of Covid-19 are quickly isolated from other patients with similar symptoms, with a simple ECP test and started taking empirical treatment.

Abstract
Amaç
Covid-19 hastalığı, moleküler, serolojik veya radyolojik yöntemlerle teşhis edilir. Bununla birlikte, bu teşhis yöntemlerine her yerde ulaşılamaz veya sonuçlanması çok fazla zaman alabilir. Bu nedenle, Covid-19 hastalarının basit ve kolay erişilebilir laboratuvar biyobelirteçleri ile etkili teşhisine ihtiyacımız var. Bu nedenle Covid-19'da Eozinofilik Katyonik Proteinin (ECP) tanısal performansını araştırdık.
Gereç ve yöntemler
Çalışmamız geriye dönük bir vaka-kontrol çalışmasıdır. 15 Mart - 15 Haziran 2020 tarihleri arasında Covid-19 teşhisi konulan 30 hastanın kaydedilen klinik, laboratuvar ve radyolojik verileri uygun istatistiksel yöntemler kullanılarak 30 sağlıklı kişi ile karşılaştırıldı.
Sonuçlar
Hastalar ve kontroller sırasıyla ortalama yaşları 57,2 ± 15,46 ve 60,07 ± 20,59 olan 10 (% 33,3) kadın ve 20 (% 66,6) erkeklerdi. Hastaların başvuru sırasındaki eozinofil sayıları kontrollere göre anlamlı olarak düşüktü (p <0.001). Yatıştan bir hafta sonra eozinofil sayıları başvuru düzeylerine göre anlamlı olarak arttı (p = 0,004). Hastaların yatışından bir hafta sonra ECP değerleri kontrollere göre anlamlı olarak düşüktü ve yatışa göre azalmıştı (sırasıyla p = 0,023, p = 0,001). Bir hafta sonraki ECP değerleri,% 46,7 duyarlılık,% 93,3 özgüllük ve ≤ 88,67 ng / mL kesme değeri ile hasta ve kontrolleri farklılaştırmıştır. ECP2'nin ROC analizi; (AUC) = 0,740, p = 0,023.
Sonuç
Covid-19 şüpheli hastaların benzer semptomları olan diğer hastalardan basit bir ECP testi ile hızlı bir şekilde izole edilmesi ve ampirik tedaviye başlanması halk sağlığı açısından büyük fayda sağlayacaktır.
