Abstract

Glucose Regulated Protein (GRP-78) plays a role in the intrusion of many viruses such as bat coronavirus, MERS-CoV, ebola virus, dengue virus, Japanese encephalitis virus, influenza virus, and Zika virus. This study, however, aims to examine the GRP-78 levels in patients who were infected with COVID-19, treated and recovered completely three months after the initiation of treatment. A total of 20 patients who were diagnosed with the COVID-19 disease and fully recovered, and who had participated in a previous study conducted by Sabırlı et al., were included in this prospective cohort study. Using the enzyme-linked immunosorbent assay (ELISA) method, the GRP-78 levels were examined in the blood samples. The mean serum GRP-78 level was found to be 1393.31 ± 306.33 pg / ml in the blood samples drawn from the patients when they were first admitted to the emergency department while the mean serum GRP-78 level measured 90 days after the initiation of treatment was 1451.73 ± 336.65 pg / ml. No statistically significant differences were found between the GRP-78 levels measured during the first admission and the follow-up control 3 months later (p = 0.451). In conclusion, this study revealed that the GRP-78 levels remained high in patients with COVID-19 infections even after 3 months following the initiation of treatment. This high GRP-78 level may provide insight into the immunity of the person against the Sars-CoV-2 virus; however, this issue should be further examined both in a cell culture study and in a longer-term cohort study.

Özet

GRP-78 proteininin bat koronavirüs, Mers-Cov, ebola virüs, deng virüsü, japon ensefalit virüsü, influenza virüs ve zika virüs gibi birçok virüsün hücreye girişinde rol oynadığı bilinmektedir. Bu çalışmada COVID-19 enfeksiyonu geçirmiş ve tedavi almış ve tamamen iyileşmiş olan hastalarda tedavi başlangıcından üç ay sonrasındaki Glucose Regulated Protein-78 (GRP-78) düzeylerini incelemeyi amaçladık. Daha öncesinde Sabırlı ve ark. tarafından yapılan çalışma grubunda yer alan, COVID-19 hastalığı tanısı almış ve hastalığı geçirip tamamen iyileşmiş olan 20 hasta prospektif kohorta dahil edildi. Hastaların acil servise ilk tanıda başvurusu ve 3 ay sonra kontrole çağrıldığında alınan kanlardan enzyme-linked immunosorbent assay (ELISA) metodu ile GRP-78 düzeyi çalışıldı. Acil servise ilk başvuruda alınan kanda serum GRP-78 düzeyi 1393,31 ± 306,33 pg/ml; tedavi başlangıcından 90 gün sonra bakılan serum GRP-78 düzeyi ise 1451,73 ± 336,65 pg/ml olarak saptandı. İlk başvuru ve 3 ay sonraki kontrolde ölçülen GRP-78 düzeyleri açısından istatistiksel olarak anlamlı farklılık saptanmadı (p=0,451). Sonuç olarak bu çalışmada COVID-19 infeksiyonunda tedavi başlangıcından 3 ay sonrasında dahi yüksek seyrettiğini ortaya koyduk. GRP-78 düzeyinin yüksek kalmasının kişinin Sars-CoV-2 virüsüne karşı immunitesi konusunda fikir verdirici olabilir fakat bu hususun gerek hücre kültürü çalışması ve gerekse daha uzun süreli kohort çalışması yapılarak incelenmesine ihtiyaç vardır.
