Histamine intolerance, also referred to as enteral histaminosis or sensitivity to dietary histamine, is a disorder associated with an impaired ability to metabolize ingested histamine that was described at the beginning of the 21st century. Although interest in histamine intolerance has considerably grown in recent years, more scientific evidence is still required to help define, diagnose and clinically manage this condition. This article will provide an updated review on histamine intolerance, mainly focusing on its etiology and the existing diagnostic and treatment strategies. In this work, a glance on histamine intoxication will also be provided, as well as the analysis of some uncertainties historically associated to histamine intoxication outbreaks that may be better explained by the existence of interindividual susceptibility to ingested histamine. In , the European Food Safety Authority EFSA issued a scientific report warning that the levels of biogenic amines found in foods marketed in European Union countries may still entail a consumer health risk [ 1 ]. Among them, histamine has the highest toxic potential, along with tyramine, and is therefore of great interest in terms of food safety. First described more than 60 years ago, the deleterious effects of excessive histamine ingestion were initially referred to as scombroid fish poisoning or scombrotoxicosis, as they were associated with the consumption of fish in this family, but the condition is now known as histamine intoxication or histamine poisoning. In recent years, another disorder associated with histamine intake, arising from an enzymatic deficiency, has been described. The inability of certain individuals to metabolize histamine in the intestine, resulting in sensitivity to normal or even low histamine levels in food, may help to explain some of the uncertainties historically associated with histamine intoxication.

They block histamine receptors on cells, reducing physical response to allergens. When a person has an allergic reaction, they may experience symptoms such as nasal congestion, sneezing , and itchy skin. Antihistamines can help ease these symptoms. This article will look at how antihistamines work, as well as the differences between first-, second-, and third-generation antihistamines and their side effects.

Antihistamines are a widely used group of medications most commonly used to treat allergic conditions. Allergic conditions, such as allergic asthma, hives, and allergies themselves, occur n when your immune system overreacts to an otherwise harmless substance, mistaking it for something more harmful. You can purchase most antihistamines over-the-counter OTC , meaning you do not need a prescription. Most are taken in pill form, but some other formulations are available. Histamine is a chemical messenger naturally made by your immune system. While histamine has helpful uses, an overproduction of it can trigger classic allergy symptoms such as a runny nose, sneezing, itching, and watery eyes. Antihistamines are used to block signaling from histamine, reducing the occurrence of these symptoms.

In a very recently published study, a team of Austrian researchers comprehensively analyzed the symptoms experienced by patients diagnosed with histamine intolerance [ 62 ]. Histamine-reduced diet and increase of serum diamine oxidase correlating to diet compliance in histamine intolerance. The information reflects fairly accurate usage, especially for people with multiple prescriptions. Acta-Protein Struct. It was decided to investigate survival and risk in two ways: by dividing the groups according to experience of use, and secondly by using end-participation models to reduce the survival bias in the first model. Plant Physiol. Food Intolerances. One factor that could explain the discordance among the prevalence data of DAO deficit in patients with disorders associated with histamine intolerance is that the parameter considered in all of them was serum DAO activity, which, a priori, would not reflect an enzymatic deficiency derived from certain intestinal pathologies. Clinical manifestations of histamine intolerance consist of a wide range of nonspecific gastrointestinal and extraintestinal symptoms, due to the ubiquitous distribution of the four histamine receptors in different organs and tissues of the body Figure 6 [ 10 , 13 , 54 , 61 ]. In single-dose evaluations, cetirizine is among the most potent of antihistamines. R06AB02 Dexchlorpheniramine. The potentiation effect of these components could help explain the differences in absorption of the same dose of histamine when ingested in isolation or in a food matrix [ 48 , 49 ]. Statistically significant reduction of histamine-associated symptoms compared to placebo. It is also possible to use a number of other known risk factors, such as non-cancerous benign breast conditions such as non-proliferative lesions or proliferative lesions with or without atypia Exists.

Canned and semipreserved oily fish derivatives. R06AD55 Hydroxyethylpromethazine, combinations. Quantification of human diamine oxidase. Moreover, patients with lactose intolerance and plasma DAO deficit showed higher end-expiratory H 2 levels and the appearance of more symptoms during the H 2 breath test in comparison with lactose-intolerant individuals with normal DAO activity [ 79 ]. As can be seen from Figures 2 and 3, the women had a longer BC-specific survival, statistically significant, as compared to the control, especially from the treatment with desloratadine and evastin. These positive effects are observed in both positive and negative ER, as can be seen in the different breast cancer molecular subtypes, e. The chemotherapeutic agent of the above pharmaceutical formulations may be anthracycline, taxane or platinum. Improved purification and properties.
