Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

In this manuscript, Takuya Omura, et al. demonstrated that the impaired humoral response in lymphoma patient after anti-CD20 antibody treatment hampers the elevation in N-IgG antibody titers inducing prolonged COVID-19 infection. I think this is important and somewhat interesting, but there are some problems as indicated below.

Major point

1.     It is considered that prolonged COVID-19 infection is caused by not only the lack of humoral immunity but also T-cell dysfunction. In this case, the patient had a history of administration of bendamustine, and her cellular immunity may have been depressed at diagnosis of COVID-19. Did she have lymphopenia? The author should discuss more precisely these points and show additional data, such as the number of lymphocytes, CD4 positive T cells, serum IgG level, and so on.

2.     In this case, the patient also had hyperosmolar hyperglycemic syndrome (HHS) when COVID-19 developed. Is there the association between HHS and COVID-19? How does the author think? It is considered that diabetes cause immunodeficiency. The author should also discuss these points more precisely.

I believe that the authors must revise or at least discuss these issues more precisely to publish in Geriatrics.

I hope that my comment is useful for the improvement of the article.

Reviewer 2 Report

Comments and Suggestions for Authors

A paper by Omura T, et al., entitled “Prolonged COVID19 infection in a patient with complete remission from follicular lymphoma with hyperosmolar hyperglycemic syndrome” is a case report on an elderly patient who was vaccinated several times against SARS-CoV-2. Yet, the high levels of viral antigens.

 

No doubt, this case report should be seen by a scientific community. However, more details on what viral antigens were tested should be given. I mean, more details on methods should be given in the text.

 

After this, this case report might be accepted.
