Brief Summary:
Fibromyalgia is a complex and common chronic pain disorder that affects 12 million Europeans Fibromyalgia causes persistent widespread pain in muscles tendons ligaments and joints as well as widespread tenderness to touch and the presence of extreme fatigue and weakness
Histamine is a molecule derived from an essential amino acid histidine It is stored in mast cells and basophils and is excreted through the intestine being degraded as it passes through the intestinal mucosa by the enzyme Diamine Oxidase DAO which is found in this area If there is any alteration in its metabolism and normal concentrations of histamine in the blood 50-70 mgl are not maintained the free circulation of this amine in high concentrations triggers undesired effects such as migraine fibromyalgia asthenia and atopy
DAO deficiency is an alteration in the metabolism of dietary histamine that occurs when there is little activity of the DAO enzyme The low activity of the enzyme causes that a concentration considered normal of histamine from food cannot be metabolized and a transepithelial penetration of exogenous histamine occurs In this way histamine passes into the bloodstream increasing its plasma concentration and once located freely in the blood it is distributed throughout different parts of the body producing adverse effects
One of the factors that causes DAO deficiency is genetics The genetic sequence of DAO is found in a fragment located on chromosome 7 7q34-q36 of the human genome There are 85 single nucleotide variants SNPs located and identified in the human DAO gene AOC1 Seven of these SNPs produce amino acid substitution being candidates to cause alterations in the metabolic capacity of the enzyme
Since histamine accumulation can trigger fibromyalgia and the enzyme DAO has been shown to degrade histamine oral supplementation with DAO food supplements prepared from pig kidney is suggested as a treatment for fibromyalgia
The objective of this study is to analyze whether DAO enzyme supplementation reduces the characteristic symptoms of fibromyalgia In addition the prevalence of DAO deficiency in women with fibromyalgia will be identified by genetic analysis of DAO deficiency from a saliva sample It will also be evaluated if patients require a lower intake of analgesics after supplementation with the enzyme DAO
