Review for 10.1186/s12876-022-02274-1 (2022)

Reviewer’s report
Title: 
Eosinophilic enteritis accompanied by cytomegalovirus disease: a case
report
Version: 
1 
Date: 
22 Nov 2021
Reviewer's report:
The presented case was informative for the reader of the journal. I have some
comment to improve the quality of the presentation.
1. Abstract. The sentence, "To taper and discontinue prednisolone without the
relapse of eosinophilic gastroenteritis, azathioprine was administered.", was
repeated in the sections of Case presentation and Conclusion. They were
redundant.
2. Line 69. "Leakage of the pleural effusion" must be "transudative pleural
effusion".
3. "Histological examination of the terminal ileum revealed infiltration of
eosinophils of >20/ high-power fields (HPF)." and "Biopsy of the terminal ileum
showed infiltration of eosinophils of >20 HPF." were stated in lines 73 to 76.
However, the statements were redundant.
4. Discussion and conclusion. Lines 105 - 106. To taper and discontinue steroids
safely, azathioprine was administered. After discontinuation of the steroids,
azathioprine helped retain a stable status. The second sentence was redundant.
5. They should not repeat results in the discussion including lines 107 - 112, 130,
and 134. The statement in Lines 140 - 141 was redundant. They should shorten
the discussion.
6. Line 86. Route of administration and amount should be stated.
7. Line 124. The meaning of "222/192 /150000 W" was not clear.
8. Although they state that "Azathioprine helped retain a stable status after
tapering and discontinuing prednisolone for approximately four years.", it is not
clear if azathioprine helped the stability. Please explain if azathioprine was really
needed and the cessation is inappropriate.
9. English should be checked by a native speaker.
