So... What are Mast Cell Diseases???
Mast cell diseases include mastocytosis, where the body produces too many mast cells, and mast cell activation syndrome (MCAS), where even the normal number of mast cells are too easily activated by a trigger to release their contents, called mediators. These mediators can cause a variety of unpredictable symptoms in both children and adults, including skin rashes, flushing, abdominal pain, bloating, nausea, vomiting, headache, bone pain and skeletal lesions, and anaphylaxis. Triggers can be heat, cold, stress (physical or emotional), perfumes or odors, medications, insect stings, and foods. These symptoms are treated with medications including antihistamines, mast cell stabilizers, and leukotriene inhibitors, while anaphylaxis is a medical emergency requiring epinephrine. Mastocytosis can affect skin and internal organs such as the bone marrow, gastrointestinal tract, liver, and spleen. Most patients with mastocytosis have cutaneous (skin) or indolent (benign) systemic forms, but aggressive disease can occur, which may require chemotherapy.

A diagnosis of mastocytosis is confirmed by a bone marrow or skin biopsy. MCAS patients do not fulfill all criteria for mastocytosis but exhibit symptoms, may or may not have increased measurable mast cell mediators (commonly tryptase, histamine or its metabolites) during or shortly after an attack and do respond to the same medications that patients with mastocytosis do.

For more detailed information on Mastocytosis and Mast Cell Diseases please refer to our Research Page (Coming Soon!!!)

19-MAY-2014 - Ketotifen Survey
Ketotifen Survey

Your input is crucial in our quest to bring Ketotifen (Zaditen – brand name) into the US market! We have a few of our physicians meeting with a representative of a pharmaceutical company who is interested in bringing ketotifen to the US. The meeting is this Wednesday, May 21, and has just been arranged last minute. To that end, we need some input for the discussion. Please answer the following questions.

Please respond to the following questions by Tuesday, May 20th:

     1. Are you currently taking Ketotifen (or Zaditen – brand name)?

     2. If yes, how are you currently ordering/receiving your prescription?
          a. Through Personal Importation (following FDA protocol)
          b. Through Compounding Pharmacies (within the US)
          c. Other (please explain)

     3. What is the cost of the medication?
          a. Cost (of monthly or three month supply)
          b. Is the cost covered by your insurance company?

     4. Dosage for the day

     5. Are you answering this mini survey from Facebook?

All personal information will remain anonymous. Results/data will be shared during discussions with potential pharmaceutical companies that are showing interest in trying to bring the product to US market. We need to stand up together and be counted…these pharmaceutical companies need to see the number of people affected by Mast Cell Disorders that are being helped by a prescription medication that is not yet available in the US! Please send all responses to (with the subject: Ketotifen Questionnaire) by Tuesday, May 20th.

Thank you in advance.

22-DEC-2013 - Boston Center of Excellence for Mastocytosis
Boston Center of Excellence for Mastocytosis

Season’s Greetings from all of us at TMS!

We have been contacted by Dr. Mariana Castells and the staff at the Boston Center of Excellence for Mastocytosis. It appears that there has been inappropriate use of their emergency paging system by some members of TMS. If you need to make an appointment, please call the clinic at 617-732-9850. If you are considering whether or not you should be seen at the Center and would like some help clarifying that from TMS, first become a member ($35.00 per year and free with an angel fund membership for those with financial difficulties), and then contact Valerie Slee, RN, BSN or Mishele Cunningham, RN, BSN at Care coordination services will only be available for TMs members starting January 1, 2014, but there is no impediment to anyone becoming a member. You can become a member by going to our web site or by sending a check made out to Jim McKee, Treasurer, The Mastocytosis Society, PO Box 129, Hastings, NE 68902-0129.

The Boston Center of Excellence Physicians are restricted by HIPPA laws about how they can function. The physicians cannot speak to any patient who is not registered at Brigham and Women’s and whom they have not seen yet, therefore, it is not possible to call and speak to Dr. Castells and Dr. Akin or any other Brigham physician in advance of a first appointment. Once you have seen them and become their patients, then you may contact them. In an emergency after hours, your physician can call the hospital and page the allergy fellow on-call for a professional physician to physician consultation on how to treat you, but no one can legally directly page Dr. Castells, Dr. Akin, etc. unless you have been instructed to do so by them after having seen them as patients.

Our relationships with these physicians are very important to the care we receive now and in the future. Dr. Castells was very gracious in her request. Please let us all comply with the same grace. Thank you. Val
