Elevated baseline serum tryptase levels assessed in the context of patients with anaphylactic symptoms suggest systemic mastocytosis and should prompt further evaluation. We describe the case of a 47 years old woman, who reported itching and dyspnoea after eating fish, shrimps or milk. Otherwise, ...
whereas β tryptase is released into the bloodstream only after mast cell activation [4], and both form the basal tryptase pool [5,6]. In mastocytosis, α tryptase levels are consistently elevated in the blood, and during anaphylactic reactions, high levels of β tryptase are released in mast...
A 42 year-old female with progressive decline in cognition and memory, fibromyalgia, hypermobility and swelling of joints, chronic abdominal pain, and recurrent infections presented for evaluation of elevated tryptase. She had tryptase levels ranging from 14-16 mcg/L, in addition to two reported ep...

Previously, we described subjects with dominantly inherited elevated basal serum tryptase levels associated with multisystem complaints including cutaneous flushing and pruritus, dysautonomia, functional gastrointestinal symptoms, chronic pain, and connective tissue abnormalities, including joint hypermobility. Here...
40 had symptoms suggestive of AAN, and 21 had isolated urticaria (IU). Average age was the same in both groups (6.47 years vs. 6.07 years). In patients with AAN, the levels of serum tryptase were significantly higher (12.41 +/- 8.9 mu g/l) than those in cases of IU (5.55 +/- ...

Background Patients with mast cell activation symptoms and elevated baseline serum tryptase (MCAS-T) may not necessarily have a clonal mast cell disorder. Many are diagnosed with hereditary alpha tryptasemia (H伪T), a genetic trait characterized by autosomal dominant inheritance of multiple copies ...

In patients with AAN, the levels of serum tryptase were significantly higher (12.41 +/- 8.9 mu g/l) than those in cases of IU (5.55 +/- 3.17 mu g/l), P = 0.0005. Among the children with AAN, those with the severest symptoms (arterial hypotension) had the highest tryptase values ...
