Interventional study (clinical trial) studies new tests, treatments, drugs, surgical procedures or devices. Because tryptase is made by mast cells, and many symptoms seen among individuals with the hereditary alpha tryptasemia syndrome have been associated with the release of mast cell-derived mediators such as histamine, several of the clinical approaches used to treat the results of mast cell activation including antihistamines may be used and often are helpful. Schliemann S, Seyfarth F, Hipler UC, Elsner P. Impact of age and heterophilic interference on the basal serum tryptase, a risk indication for anaphylaxis, in 1,092 dermatology patients.

In some instances, a team of professionals that work together at a research or teaching hospital may be used to holistically care for your disease rather than coordinating care among individual specialists from different locations.These hospitals tend to be associated with universities or research facilities and usually have the latest technologies that may not be found in standard hospitals/clinics.Find hospitals in your area using Care Compare 'Hospitals' by typing in your zip code (directory by the Centers for Medicare & Medicaid Services). Upon mast cell activation, degranulation releases mature tryptase, which is almost exclusively in the form of beta-tryptase. Tryptase is an enzyme that is released by mast cells (along with histamine), and it is involved in activating more mast cells, increasing cytokine activity, and is even involved in connective tissue regeneration. Tryptase, a neutral protease, is a dominant protein component of the secretory granules of human mast cells. Able and willing to comply with the protocol and the restrictions and assessments therein. Recently, a new syndrome, namely - hereditary alpha tryptasemia, has been defined, originating from multiple copies of TPSAB1, the alpha-tryptase encoding gene.

Hereditary alpha-tryptasemia (HT) is an autosomal dominant genetic trait found in 4% to 6% of the general population and defined by excess copies of alpha-tryptase at TPSAB1.Elevated basal serum tryptase (sBT >8 ng/mL) is a defining feature of HT and appears to result from increased pro-alpha-tryptase synthesis and secretion rather than mast cell activation. Phenotypically, these deletions result in 4 categories of disease expression: -Deletion of 1 alpha-chain: Silent carrier state, with a normal phenotype, -Deletion of 2 alpha-chains: Alpha-thalassemia trait (alpha-1 thalassemia), with mild hematologic changes but no major clinical difficulties, -Deletion of 3 alpha-chains: Hemoglobin H disease, which is extremely variable but usually includes anemia due to hemolysis, jaundice, and hepatosplenomegaly, -Deletion of all 4 alpha-chains: Hemoglobin Bart, with hydrops fetalis and almost invariably in utero demise.
