Detection of clonal MCD is important since it will have significant consequences for management of HVA. Therefore, we recommend patients with HVA be systematically screened for clonal MCD. The pre-test probability of clonal MCD can be assessed in a stepwise fashion starting with examination of the skin for typical monomorphic maculopapular cutaneous mastocytosis (MPCM) lesions; measurement of the baseline serum tryptase (BST) and tryptase genotyping for patients with BST>11 ng/mL; followed by the REMA score which is calculated by utilizing anaphylaxis clinical features, BST, and patient sex. A bone marrow biopsy should be performed in patients with monomorphic MPCM, a REMA score ≥2, or an elevated BST based upon tryptase genotype. Patients with HVA and a clonal MCD should be treated with immunotherapy directed against the Hymenoptera venom for which they are sensitized. For this high-risk subgroup of HVA patients, it is recommended to continue immunotherapy for more than 5 years or indefinitely and to carry at least three epinephrine autoinjectors.
