In patients with a deficiency in histamine degradation due to variants in the AOC1 gene that encodes diamine oxidase enzyme, a diet high in histamine has been observed to trigger migraines, that suggests a potential functional relationship between exogenous histamine and CGRP, which could be instrumental in understanding the genesis of diet ...
[3] [1] There is a great heterogeneity in the type of foods that are advised against for histamine intolerant individuals, and a review found that exclusion of 32% of foods could be explained by the occurrence of high contents of histamine, while there was a range of excluded foods with an absence or very low levels of biogenic amines including ...
DAO levels in the blood circulation increase vastly in pregnant women suggesting a protective mechanism against adverse histamine. [12] Histamine is a potent vasodilator and can cause uterine contractions, which can lead to premature labor. DAO in the placenta breaks down histamine to prevent its accumulation and maintain a healthy pregnancy.
On a molecular level, there were scientists who sought to find more precise lists of chemicals which could have histamine-liberating potencies. For instance, in a scientific journal, MacIntosh and Paton publicized a list of various compounds thought to be histamine liberators, such as organic bases, amines and guanidines . [ 8 ]
Packages of frozen yellow fin tuna steaks sold at Whole Foods Market stores in more than two dozen states are being recalled due to concerns about high levels of histamine that could cause a ...
Mast cell activation syndrome (MCAS) is a term referring to one of two types of mast cell activation disorder (MCAD); the other type is idiopathic MCAD. [1] MCAS is an immunological condition in which mast cells, a type of white blood cell, inappropriately and excessively release chemical mediators, such as histamine, resulting in a range of chronic symptoms, sometimes including anaphylaxis or ...
Isolated reports of scombroid food poisoning in humans caused by histamine present in the tissues of stale or rotten scombroid fish, usually tuna, have occurred over the years. In September 2016, authorities in Singapore intercepted canned tuna imported from Thailand after finding high levels of histamine. [12] No human cases were reported.
The attained high levels of cAMP persist during histamine release. It was further found that catecholamines do not markedly alter the fluoride-induced histamine release. It was also confirmed that the second, but not the first, step in sodium fluoride-induced histamine secretion is inhibited by theophylline. [33]
