Bruton's tyrosine kinase inhibition for the treatment of allergic disorders.

IgE signaling through its high-affinity receptor FcεRI is central to the pathogenesis of numerous allergic disorders. Oral inhibitors of Bruton's tyrosine kinase (BTKis), which are currently Food and Drug Administration-approved for treating B cell malignancies, broadly inhibit the FcεRI pathway in human mast cells and basophils, and therefore may be effective allergen-independent therapies for a variety of allergic diseases. The application of these drugs to the allergy space was previously limited by the low kinase selectivity and subsequent toxicities of early-generation compounds.

A phase II study of Bruton's tyrosine kinase inhibition for the prevention of anaphylaxis.

BACKGROUNDIgE-mediated anaphylaxis is a potentially fatal systemic allergic reaction for which there are no currently FDA-approved preventative therapies. Bruton's tyrosine kinase (BTK) is an essential enzyme for IgE-mediated signaling pathways and is an ideal pharmacologic target to prevent allergic reactions. In this open-label trial, we evaluated the safety and efficacy of acalabrutinib, a BTK inhibitor that is FDA approved to treat some B cell malignancies, in preventing clinical reactivity to peanut in adults with peanut allergy.

Bruton's tyrosine kinase inhibition for the prevention of anaphylaxis: an open-label, phase 2 trial.

IgE-mediated anaphylaxis is a potentially fatal systemic allergic reaction for which there are no known preventative therapies. Bruton's tyrosine kinase (BTK) is an essential enzyme for IgE-mediated signaling pathways, and is an ideal pharmacologic target to prevent allergic reactions. In this open-label trial (NCT05038904), we evaluated the safety and efficacy of acalabrutinib, a BTK inhibitor that is FDA-approved to treat some B cell malignancies, in preventing clinical reactivity to peanut in adults with IgE-mediated peanut allergy.

Reticular Erythematous Mucinosis: A Rare Cutaneous.

Reticular erythematous mucinosis (REM) is a rare form of primary cutaneous mucinosis, most often involving the midline of the upper chest or back in middle-aged women. REM bears clinical and histopathologic resemblance to lupus erythematosus tumidus (LET), dermatomyositis, scleredema, and lichen myxedematosus. Early recognition and diagnosis of REM is particularly relevant to exclude the abovementioned diseases, as REM is more benign and has fewer systemic consequences.
