Abstract
BACKGROUND

Severe acute respiratory syndrome coronavirus 2 is the virus responsible for coronavirus disease 2019 (COVID-19), a disease that has been blamed for inducing or exacerbating symptoms in patients with autoimmune diseases. Crohn's disease (CD) is an inflammatory bowel disease that affects genetically susceptible patients who develop an abnormal mucosal immune response to the intestinal microbiota. Patients who underwent hematopoietic stem cell transplantation (HSCT) are considered at risk for COVID-19.

AIM

To describe for the first time the impact of COVID-19 in CD patients who had undergone autologous, non-myeloablative HSCT.

METHODS

In this descriptive study a series of 19 patients were diagnosed with positive COVID-19. For two patients there were reports of the occurrence of two infectious episodes. Parameters related to HSCT, such as time elapsed since the procedure, vaccination status, CD status before and after infection, and clinical manifestations resulting from COVID-19, were evaluated.

RESULTS

Among the patients with COVID-19, three, who underwent Auto HSCT less than six months ago, relapsed and one, in addition to the CD symptoms, started to present thyroid impairment with positive anti-TPO. Only one of the patients required hospitalization for five days to treat COVID-19 and remained in CD clinical remission. Nine patients reported late symptoms that may be related to COVID-19. There were no deaths, and a statistical evaluation of the series of COVID-19 patients compared to those who did not present any infectious episode did not identify significant differences regarding the analyzed parameters.

CONCLUSION

Despite the change in CD status in three patients and the presence of nine patients with late symptoms, we can conclude that there was no significant adverse impact concerning COVID-19 in the evaluated patients who underwent HSCT to treat CD.

Core Tip: This report discusses the impact of coronavirus disease 2019 (COVID-19) on 50 patients with Crohn's disease (CD) who underwent autologous hematopoietic stem cell transplantation between 2013 and 2021. Of these patients, 19 were diagnosed with COVID-19, with two patients reporting two infectious episodes each and in three there was a change in the CD status. One patient required hospitalization, but there were no deaths. Overall, the study found no significant adverse impact of COVID-19 on these patients.
