“…32,47,48 There have been multiple case reports of excessive bleeding in patients with SM. [49][50][51] The propensity to bleed is unlikely related to thrombocytopenia (which is usually mild), but instead may be related to heparin-like anticoagulants caused by MC degranulation, along with the disruption of fibrinogen function by trypase. 51,52 Importantly, the increase in MC burden does not affect B-cell and T-cell number or function and, therefore, patients with SM are not immunocompromised, except in cases of advanced SM and SM-AHNMD when the bone marrow is directly affected.…”
