I have answered the 107 questions I have been asked most in the last four years. No jargon. No terminology. Just answers.
19. How do other conditions affect mast cell disease?
• Mast cell activity can affect literally every system in the body.
• Mast cells are found throughout the body and live in many tissues and organs in significant numbers.
• There are essentially three types of damaging mast cell activity:
–Normal mast cells are getting bad signals from other cells and they do bad things. This is not mast cell disease because these mast cells are not broken. They are getting signals from other broken cells.
–Abnormal mast cells do bad things and tell other nearby cells to do bad things. This is mast cell disease, specifically mast cell activation syndrome and sometimes monoclonal mast cell activation syndrome.
–You make way too many mast cells, they are abnormal, they do bad things, and they tell other nearby cells to do bad things. This is mast cell disease, specifically all forms of mastocytosis (systemic, cutaneous, and mast cell leukemia), sometimes monoclonal mast cell activation syndrome and mast cell tumors (mastocytoma and mast cell sarcoma).
• Generally speaking, if you have mast cell disease, any other condition you have will irritate your mast cell disease. This can also work the other way around and mast cell disease can irritate your other conditions.
• Many conditions naturally trigger higher level mast cell activation.
• Any disease that causes your body to make a lot of cells very quickly is likely to trigger to mast cell activation. Cancers are mast cell activating. Non cancerous diseases where you make too many blood cells at once, like polycythemia vera or essential thrombocythemia, are are mast cell activating.
• Mast cells are usually found very close to tumors. Sometimes, they are found inside tumors. Mast cells are important for tumors to survive because they can make blood vessels to bring tumors the blood they need.
• Diseases affecting the immune system are triggering to mast cells. In fact, many patients have mast cell activation syndrome caused by the immune disease irritating their mast cells so much. Many mast cell patients have autoimmune diseases like lupus or rheumatoid arthritis. Many patients also have deficiencies in their immune system. Because mast cells are immune cells, they are very responsive to signals from other immune cells. Mast cells think those cells need help from them to fight an infection or disease so they respond strongly to “help”.
• Diseases that cause inflammation also trigger mast cells. This can happen whether the inflammation is local or not. Systemic inflammation is more irritating to mast cells since that kind of inflammation can find more mast cells throughout the body. Local inflammation can irritate mast cells nearby. It can also call mast cells from other parts of the body to that location.
• Mast cells are actively involved in fighting infections from viruses, bacteria, fungi, and parasites. This is the reason many mast cell patients find they are more reactive when they have even a minor illness, like a cold.
• Any type of physical stress can activate mast cells. This can be something as simple as exercise or something more traumatic such as a car accident, a surgery, or childbirth. Even things that should be easy to recover from can activate mast cells, like a small cut, dehydration, or getting overheated. This also includes stress caused by another disease.
• Emotional stress can activate mast cells, even if the big emotion is joy.
