What is mast cell activation syndrome?
Mast cell activation syndrome is a multi-organ, multi-symptom disorder characterized by clinical features and responses to medications that block mast cells. While some laboratory testing can be used to support the diagnosis, there are no diagnostic biomarkers for clinical use, which has hampered clinical care and research. Furthermore, lay literature and social media are outpacing the science, which has led to controversy with regards to diagnostic criteria and treatments. In this review, we will help to explain what mast cell activation syndrome is, and is not, with an emphasis on gastrointestinal manifestations and the therapeutic role of nutrition.
What are the diagnostic criteria for i-mcas?
An important part of the proposed diagnostic criteria for i-MCAS is that no other condition better explains the symptoms and manifestations of the patient. In those with prominent GI symptoms, appropriate tests should be undertaken to rule out inflammatory conditions (e.g. inflammatory bowel diseases, celiac disease, eosinophilic disorders), GI tract malignancies, or anatomic defects. Small intestinal bacteria l overgrowth.31 may mimic symptoms of mast cell activation or be found concurrently in patients with MCAS. Although there is no published data, patients with MCAS report frequent exposure to antibiotics and may therefore have at least an intestinal dysbiosis. Bile salt diarrhea is also possible, especially in those patients who have had cholecystectomies and/or other abdominal surgeries in previous efforts to address patients’ symptoms.32 GI motility disturbances due to autonomic dysfunction should also be ruled out due to the overlap in patients with MCAS and dysautonomia. Bear in mind that MCAS patients can have more than one diagnosis.
What are the symptoms of i-mca?
Chronic symptom disorders that may be confused with i-MCAS include chronic pain syndromes, chronic fatigue syndrome, fibromyalgia, multiple chemical sensitivity syndrome, and chronic symptom syndromes following infections or other exposures such as the chronic Lyme disease syndrome. Various auto-immune diseases, endocrinopathies, and psychiatric conditions should also be in the differential for i-MCAS, and if present, may better explain the patient’s presentation.
Do mast cells have a GI function?
Mast cells have many known physiologic functions in the GI tract, so it is not surprising that a condition where there is aberrant activation of mast cells may lead to multiple GI symptoms and manifestations.
Is I-MCAS increasing?
The incidence and prevalence of i-MCAS may be increasing in many societies perhaps in parallel with other allergic and atopic conditions. With a current paucity of diagnostic biomarkers and robust clinical and scientific literature to support the pathology of mast cell activation in patients with the multi-symptom disorder, there is a lack of provider awareness of i-MCAS. Furthermore, the lay literature on the Internet, social media “experts”, and patient blogs are outpacing the science. We therefore have to remain faithful to the proposed diagnostic criteria for patients with suspected i-MCAS and continue to expand our research to be able to develop more objective biomarkers. Patients with i-MCAS do exist in your practice and we have outlined clinical management approaches that will undoubtedly help them.
