Abstract

Background: Coronavirus disease-19 (COVID-19), resulting from infection with SARS-CoV-2, spans a wide spectrum of illness. In severely ill patients, highly elevated serum levels of certain cytokines and considerable cytolytic T cell infiltrates in the lungs have been observed. These same patients may bear low to negligible viral burdens suggesting that an overactive immune response, often termed cytokine storm, contributes to the severity of COVID-19. We report the safety and efficacy of baricitinib combined with remdesivir and dexamethasone in 45 hospitalized patients with COVID-19 pneumonia at a tertiary academic medical center.

Methods: Retrospective review of 45 patients hospitalized with COVID-19 pneumonia. Patients received 7-day course of baricitinib, 5-day course of remdesivir and 10-day course of dexamethasone. Clinical status and biomarkers were obtained daily. Outcomes assessed include mortality, duration of hospitalization, presence of shock, need for supplemental oxygen, need for non-invasive ventilation, need for mechanical ventilation and development of thrombosis.

Results: Obesity and multiple medical comorbidities were associated with hospitalization in the setting of COVID-19. Treated patients demonstrated rapid declines of C-reactive protein (CRP), ferritin and D-dimer with gradual improvement in hemoglobin, platelet counts and clinical status. Only 2 of 45 (4.4%) treated patients required mechanical ventilation after initiating treatment and there were six deaths (13.3%).Only 2 of 45 (4.4%) treated patients required mechanical ventilation after initiating treatment. There were six deaths (13.3%) and these were associated with lower BMI.

Conclusions: These findings support the utility of immunosuppression via JAK inhibition in moderate to severe COVID-19 pneumonia.
