ClinicalTrials.gov, an affiliate of NIH, provides current information on clinical research studies in the United States and abroad. It is made primarily by cells that are present around blood vessels and in the bone marrow called mast cells, and it is used largely as a marker for mast cell activation, as it can be easily measured by a blood test, especially after certain allergic reactions. These symptoms may include allergic-like symptoms such as skin itching, flushing, hives, and even anaphylaxis; gastrointestinal (GI) symptoms such as bloating, abdominal pain, diarrhea and/or constipation (frequently diagnosed as irritable bowel syndrome or IBS), heartburn, reflux, and difficulty swallowing; connective tissue symptoms such as hypermobile joints and scoliosis; cardiac symptoms such as a racing or pounding heartbeat or blood pressure swings sometimes with fainting; as well as anxiety, depression, chronic pain, panic attacks, and others.

They can provide therapy and prescribe medications. Palliative radiation to localized sites is permitted in Phase 2. (1) Both are expressed as inactive proenzymes. It is also possible that the increased tryptase itself causes the symptoms without requiring mast cells to be activated, or it could cause an abnormally increased response to otherwise normal mast cell activation, which might explain why so many patients respond to medications that target mast cells and substances released by mast cells.
