It can cause severe cytokine storms leading to intensive care unit admission requiring mechanical ventilation. However, there have been few studies establishing the outcomes of chronic myeloid leukemia (CML) patients on tyrosine kinase inhibitors who are infected with COVID-19. We present a 69-year-old male with a history of CML on imatinib therapy with COVID-19 who developed acute respiratory distress syndrome needing mechanical ventilatory support, shock requiring vasopressors, and worse outcome secondary to blast crisis.
