Abstract

BARRANCO-LAMPON, Gilberto et al. COVID-19 in patients with hematological diseases. Gac. Méd. Méx [online]. 2021, vol.157, suppl.3, pp.S3-S9.  Epub Apr 25, 2022. ISSN 2696-1288.  https://doi.org/10.24875/gmm.m21000488.

Initial reports suggested that patients with a history or active malignancy may be at increased risk of contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and developing complications related to coronavirus disease 2019 (COVID-19). Patients with benign and malignant hematological pathologies may be immunocompromised by the effects of antineoplastic therapy, supportive medications such as steroids, and the immunosuppressive properties of the cancer itself. They may also have an increased immune response to infection secondary to immunomodulatory drugs. COVID-19, caused by SARS-CoV-2, is expected to be an infection devastating in many patients with hematologic diseases. The first confirmed cases in Mexico were on March 1, 2020; In our hematology service, the first case reported and confirmed was in April 2020. We conducted a case series study of 33 hospitalized patients with benign and malignant pathologies that developed COVID-19. The COVID-19 case rates in hospitalized subjects with hematological pathologies was 15.7%. The mortality from COVID-19 was 54.54%. In patients with hematological pathologies it seems to be mainly due to the fact that patients with active cancer without a complete response who received cytotoxic chemotherapy or other anti-cancer treatment cancer have a higher risk of mortality from COVID-19 compared to those who do not receive active treatment, patients de novo without chemotherapy, but in advanced stages of the disease with comorbidities and associated mainly with bacterial coinfections.
