Informes recientes revelan una estrecha relación entre la migraña y los trastornos gastrointestinales (GI), como la enfermedad celíaca (EC) y la sensibilidad al gluten no celíaca (NCGS). La EC es un trastorno genético autoinmune, que afecta la mucosa del intestino delgado.
Migraine is a common neurovascular disorder affected by various levels of neurotransmitters. Low histamine metabolism is also related with pathophysiology of migraine.
As diamine oxidase (DAO) gene variants are linked with higher levels of histamine in migraine patients, we investigated the possible relationship of two variants rs2052129 and rs10156191 of this gene with migraine risk in North Indian population.
We read with interest the manuscript by Onderwater et al. that reported on alcoholic beverages as a trigger factor for migraines [1]. Although, epidemiological studies have found a correlation between alcohol intake and headaches, a specific pathophysiologic mechanism of this headache remains unidentified [2].
Multiple Sclerosis (MS) is an autoimmune disease of the central nervous system, mostly affecting young adults. Diamine oxidase is an enzyme essential for histamine production. Histamine which is produced mostly by mast cells can have effects on different aspects of immune system via its different histamine receptors (H1R, H2R, H3R and H4R).
Low-histamine diets are currently used to reduce symptoms of histamine intolerance, a disorder in histamine homeostasis that increases plasma levels, mainly due to reduced diamine-oxidase (DAO) activity. These diets exclude foods, many of them of plant origin, which patients associate with the onset of the symptomatology.
Histamine intolerance represents a controversially discussed disorder. Besides an impaired degradation of orally supplied histamine due to diamine oxidase (DAO) deficiency, a deranged gut flora may also contribute to elevated histamine levels
Diagnosis of histamine intolerance (HIT) has been based on low serum diamine oxidase (DAO) values, functional gastrointestinal disorders and improvement of symptoms with a histamine-reduced diet (HRD). In a retrospective analysis of outpatients’ charts we identified 101 patients with HIT. After a median of 13 months, a questionnaire was distributed to the patients so that they could be classified into four diet-compliance groups.
Low-histamine diets and/or exogenous diamine oxidase (DAO) supplementation are currently used to treat symptoms of histamine intolerance (IH), a disorder in histamine homeostasis that increases its plasma levels, mainly dou to DAO deficiency. Headache is the most recognized symptoms.
Human extravillous trophoblast (EVT) invasion of the pregnant uterus constitutes a pivotal event for the establishment of the maternal-fetal interface. Compromised EVT function manifesting in inadequate arterial remodeling is associated with the severe pregnancy disorder early-onset preeclampsia (eoPE).
