Round 1

Reviewer 1 Report

1.       How did the author predict and select the MicroRNAs?

2.       What is the home message of the study?

3.       Mention the limitation and future studies. Such as PMID: 35476290, PMID: 35476290

4.       The author can analyze of roc cure for the viral microRNAs.

5.       Draw a flowchart  based on the PRISMA guideline.

6.       The author believed that “Twelve of the predicted gene targets have been validated in plasma/serum, reflecting their potential use as predictive prognosis biomarkers.” In the laboratory, we can diagnose and prognosis COVID-19 via the validation genes and primers. Hence, what is the novelty of this study?

7.       Roc cure is the vital analysis I think the author has to focus on in this section.

 

8.       miR-155, mir-146a was evaluated before. Why did the author select these miRs?

Reviewer 2 Report

The manuscript "miR-146a, miR-221 and miR-155 are involved in inflammatory 2 immune response for severe covid-19 patients” is an interesting well-written research article that focuses on the identification of biomarkers involved in the pathological progression of COVID. However, I have some comments/ suggestions that may help improve the paper:

-To maintain the denomination of miR-146a during the text.

-To explain the reason to include miR-16 in this study. Applied biosystems recommend the use of this miR as endogenous control, but in some protocols, this miR is used as control of hemolysis.

-To note the limits in using the U6 as a control in plasma. U6 snRNA previously have been used to normalize circulating miRNAs in RT-qPCR analyses, but recently was demonstrated that this non-coding RNA has a lower stability and is less abundant than miRNAs in circulating. Moreover, this non-coding RNA does not reflect the biological properties of miRNAs and is highly expressed in tissues, but its expression in plasma is very low.

-In conclusion as preferable to indicate a correlation between total cholesterol and miR-221 in the same paraph there, you speak about this miR.

 

-I am not agreeing that the assessed ROC curve had excellent performance because, despite the fact as AUC is 0,95, the specificity of this curve is not high (about 0,6).
