32345646 As the SARS-CoV-2 (COVID19) pandemic spreads and the number of Bruton’s tyrosine kinase inhibitor (BTKi)-treated COVID19 affected patients grows, we must consider the pros and cons of BTKi discontinuation for our patients. […] In favor of BTKi continuation, BTK plays an active role in macrophage polarization. […] By modulating key transcription factors, BTK may regulate macrophage polarization downstream of classic M1 and M2 polarizing stimuli and mitigate the hyperinflammatory state associated with COVID19. […] In favor of BTKi discontinuation, we note a potentially increased risk of secondary infections or impaired humoral immunity. […] We hypothesize that the potential benefit of blunting a hyper-inflammatory response to SARS-CoV-2 through attenuation of M1 polarization outweighs the potential risk of impaired humoral immunity, not to mention the risk of rapid progression of B-cell malignancy following BTKi interruption. […] Based on this, we suggest continuing BTKi in patients with COVID19.
32503877 Bruton tyrosine kinase (BTK) regulates macrophage signaling and activation. […] Acalabrutinib, a selective BTK inhibitor, was administered off-label to 19 patients hospitalized with severe COVID-19 (11 on supplemental oxygen; 8 on mechanical ventilation), 18 of whom had increasing oxygen requirements at baseline. […] Ex vivo analysis revealed significantly elevated BTK activity, as evidenced by autophosphorylation, and increased IL-6 production in blood monocytes from patients with severe COVID-19 compared with blood monocytes from healthy volunteers. […] These results suggest that targeting excessive host inflammation with a BTK inhibitor is a therapeutic strategy in severe COVID-19 and has led to a confirmatory international prospective randomized controlled clinical trial.
