Conclusions
The current manuscript may be the first one performing periostin ELISA on COVID serum, and we believe that periostin can be used as a new biomarker.
Methods
In the study, 32 patients followed up during May to July 2020 because of COVID-19 and 24 healthy controls were included. The patients were divided into two groups, namely, mild/moderate and severe, according to the severity of the disease. Serum periostin and transforming growth factor beta (TGF-β) levels were tested using an enzyme-linked immunosorbent assay (ELISA) method using commercially available ELISA kits.
Results
It was observed that the periostin level was significantly higher in both mild/moderate cases and severe cases compared with the control group at first presentation. However, TGF-β levels at first presentation were similar between the groups. Conclusions: The current manuscript may be the first one performing periostin ELISA on COVID serum, and we believe that periostin can be used as a new biomarker.
