Unveiling Mast Cell & Fibromyalgia Connection

Fibromyalgia comes with many comorbid conditions that can be directly affected by mast cell reactions. Some conditions can include bladder pain syndrome/interstitial cystitis (BPS/IC), gastrointestinal symptoms (GI), neurologic inflammation and pain, and mast cell dysfunction and disorders.

Mast cells in the skin are the guardians that quickly react to stimuli that disturb a person’s homeostasis. Mast Cells (MCs) are found in the mucous membranes of the respiratory along with the digestive tract along with submucosa and connective tissue adjacent to the conjunctiva and skin. MCs are part of the pathogenesis of allergic, auto inflammatory and cancer disease as well.

Since our skin is the largest organ of the body that protects us from external physical, chemical, along with microbiological factors. MCs are one of the representatives that react first in the immune response. MCs are part of both the innate and adaptive immune responses.

Neurological Inflammation & Pain

Thalamic mast cells contribute to inflammation and pain, by releasing neuro-sensitizing molecules that include histamine, IL-1β, IL-6 and TNF, as well as calcitonin-gene related peptide (CGRP), HK-1 and SP. These molecules could either stimulate thalamic nociceptive neurons directly, or via stimulation of microglia in the diencephalon. As a result, inhibiting mast cell stimulation could be used as a novel approach for reducing pain and the symptoms of FMS,” states the PubMed website.

Bladder Pain Syndrome/Interstitial Cystitis (BPS/IC)

Mast cells involved in allergic reactions are distributed throughout the blood vessels, lymph glands, and nerves of the bladder, as well as the bladder smooth muscle and mucosa. Mast cells activated by the involvement of neurological, immune, and endocrine factors are thought to play a central role in the progression of IC/BPS in many patients,” states the International Neurology Journal website.

Gastrointestinal Pain & Inflammation

Diet modification in patients with fibromyalgia by specific histamine release test improves certain clinical parameters related to the symptoms of the digestive sphere, compared to the control group. Our work opens a possible way of non-pharmacological treatment to improve some symptoms of this very prevalent disease,” states the Rheumatologia website.

The identification of the DAO enzyme deficiency in FMS patients has made it obvious that histamine and mast cell reactions directly correlate for a lot of the sub symptoms of Fibromyalgia and it’s associated pain.

Associations between fibromyalgia symptoms and candidate variants of the AOC1 gene in DAO enzyme activity. Identification of reduced DAO activity may improve the quality of life and treatment of symptoms in fibromyalgia patients.” states the Frontiers website when discussing Frontiers in Genetics.

DAO is an enzyme stored in tissues but primarily are found in the renal and intestinal mucosa. DAO’s purpose is to catabolize, or break down, histamine and diamines. Deficiency in DAO can create Histamine Intolerance (HIT). This can lead to neurological, gastrointestinal, and epidermal disorders.

What is recommended to assist patients in treatment is an elimination diet of high histamine foods can help patients along with recommendations of the following:

Inhibitors of mast cells would be useful in the treatment of FMS. Natural molecules could include the flavonoids, luteolin and tetramethoxyluteolin, alone or in combination with other substances selected to reduce stress. Other natural molecules could include palmitoylethanolamide, which apparently inhibits neuro-inflammation and reduces pain,” states the Frontiers in Cellular Neurology website .

ANTIHISTAMINES – Receptor Blocking

H1, H2, H3, H4 Receptor Blockers

” Histamine receptors are located throughout the human body and have been classified into categories H1, H2, H3, and H4.Generally speaking, H1 receptors account for neuronal and nervous system sites, H2 are more related to stomach and digestive function, H3 receptors are found in the brain, and H4 are found in organs and bone marrow. Both H1 and H2 receptors are found in airway tissues, skin tissue, and immune cells.” Found on this website — https://www.optimusmedica.com/otc-antihistamines/#:~:text=Histamine%20receptors%20are%20located%20throughout%20the%20human%20body,H4%20are%20found%20in%20organs%20and%20bone%20marrow.

What has worked for me is in immediate flare of a critical reaction, I choose to take a Generation 1 antihistamine which is Diphenhydramine (Benedryl). However, long term use has indicated that it can cause or create dementia/Alzheimer’s or at least exasperates symptoms. I had been using Diphenhydramine for years, because the allergy shots never worked, and I’m allergic to steroids and Prednisone. So I gave that up. I had to do something.

Once I verified exactly what symptoms I was suffering from, and then figured out what receptors I needed to block, and what drugs coordinated with the ones I searched up. What worked for me was H1 and H2 blockers, which was Cetirizine (Zyrtec) and Famotidine (Pepcid AC)

Since I already was diagnosed with Fibromyalgia, and Neuropathy (even my feet were killing me and I wasn’t on them) along with my GI tract flaring, I knew that the only way for me to calm down my whole body was to block my H1 receptors and H2 receptors from antihistamine. My skin was reacting as well by the time I was diagnosed. Showers felt like whole body tattoos all at once, even the water hurt my skin like tiny needles. Each person is different, and each person will have different results and responses.

**Note: I was a guinea pig, and my primary physician was on board. He told me, “a serving suggestion is very literally a suggestion, you can take MORE of a antihistamine than what is suggested, so it took a lot of trying one , and upping the dose. My dosage is 4 times a day. 30 minutes before eating , Morning wake-up, Lunch, Dinner, and then 30 minutes before bed, to account for the histamine dump while I sleep to fight the insomnia and night sweats, when I forget to take them.

**Always check with your primary physician when taking OTC or Prescription medications. They are not pharmacy technicians, but it is important to discuss uses if you are on any other medications as well!**
