| T3 | 0-12 | Sentence | denotes | Dear Editor, |
| T4 | 13-184 | Sentence | denotes | Zhang et al. [1] discussed the use of tocilizumab, a monoclonal anti-IL-6 receptor antibody, in the treatment of cytokine release syndrome associated with severe COVID-19. |
| T5 | 185-361 | Sentence | denotes | Although tocilizumab may be beneficial in selected COVID-19 patients with a counterproductive hyperinflammatory phenotype, the efficacy and safety of such treatment is unknown. |
| T6 | 362-480 | Sentence | denotes | Tocilizumab is primarily used for rheumatological conditions, including rheumatoid arthritis and giant cell arteritis. |
| T7 | 481-689 | Sentence | denotes | Rheumatologists have extensive experience using tocilizumab; however, this may not be the case for intensivists, infectious disease specialists, and other physicians treating critically ill COVID-19 patients. |
| T8 | 690-802 | Sentence | denotes | Therefore, we would like to highlight a rare but feared complication of tocilizumab: intestinal perforation [2]. |
| T9 | 803-964 | Sentence | denotes | The mechanism for intestinal perforation in patients receiving tocilizumab is not fully understood, but prior diverticulitis has been noted as a risk factor [2]. |
| T10 | 965-1094 | Sentence | denotes | The human host receptor of SARS-CoV-2 is angiotensin-converting enzyme 2 (ACE2), which is highly expressed in the intestines [3]. |
| T11 | 1095-1247 | Sentence | denotes | Intestinal viral replication is likely considering the ACE2 expression, gastrointestinal symptoms and presence of SARS-CoV-2 RNA in fecal samples [4,5]. |
| T12 | 1248-1355 | Sentence | denotes | Some gastrointestinal symptoms, such as abdominal pain, are associated with increased disease severity [5]. |
| T13 | 1356-1530 | Sentence | denotes | Furthermore, critically ill COVID-19 patients may have altered hemodynamics, potentially leading to intestinal hypoperfusion that can compromise intestinal mucosal integrity. |
| T14 | 1531-1759 | Sentence | denotes | More studies are required to evaluate whether these variables influence the risk of intestinal perforation with tocilizumab in critical COVID-19 cases; however, clinicians should be aware of the potential for this adverse event. |
| T15 | 1760-1982 | Sentence | denotes | Lastly, as tocilizumab attenuates the acute phase response, intestinal perforation may not necessarily cause significant C-reactive protein (CRP) elevation and may initially go unnoticed in sedated and ventilated patients. |
| T16 | 1984-1996 | Sentence | denotes | Declarations |
| T17 | 1997-2005 | Sentence | denotes | Funding: |
