Treatment strategies for patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continue to be heavily researched and ever-changing. Recent data has suggested that combination therapy with dexamethasone, remdesivir and baricitinib could decrease the severity and length of illness in patients with severe SARS-CoV-2. However; the data regarding the safety and side effects related to this combination therapy are limited to case reports. The purpose of this case report is to highlight a potentially life-threatening side effect of one or all medications mentioned above.
Learning points:
Current National Institutes of Health treatment guidelines recommend remdesivir for patients with a high risk of progression. In patients requiring minimal supplemental oxygen, remdesivir or dexamethasone monotherapy is recommended, while in patients requiring high-flow oxygen or non-invasive ventilation, dexamethasone monotherapy or dexamethasone plus remdesivir is recommended. Baricitinib or tocilizumab can be added in patients requiring oxygen supplementation.Clinicians should be aware of transient leukocytopenia that can be induced with combination therapy of dexamethasone, remdesivir and baricitinib during the early phase of treatment of SARS-CoV-2 patients.The evaluation approach for leukopenia should consider autoimmune disorders, inflammatory diseases, infections, malignancy, and medication and toxin exposure.
