Background: 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 rs10156191of this gene with migraine risk in North Indian population.
Methods: A case-control study for 250 migraine patients and 250 matched healthy controls was conducted by
polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).
Results: We found statistically significant differences in allelic frequencies of rs2052129 (p = .009, OR = 1.462;
95% CI: 1.098–1.947) and rs10156191 (p = .019, OR = 1.430; 95% CI: 1.060–1.928) variants in DAO gene. For
rs1015691, we were able to show statistically significant association at all genotypic, dominant and allelic levels
in both MA (for T allele, p = .020; OR = 1.662, 95% CI: 1.083–2.551) as well as in female subgroup (for T allele,
p = .025, OR = 1.460; 95% CI: 1.049–2.033). But no such significant association was found in clinical sub
grouping of migraine in rs2052129 as p > .05. However in gender analysis, protective effect of T allele in male
migraine patients for rs2052129 (OR < 1) was found.
Conclusions: Our findings clearly indicated that female patient with rs10156191T allele and in MA subgroup
showed an increased risk for migraine. Our data also indicated that rs2052129T variant showed a significant role
in migraine susceptibility of this population.

Abstract
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]. Particularly red wine was documented as the most common trigger for migraines in this evaluated population [1]. Most commonly found biogenic amines in wine – histamine, tyramine, phenylethylamine, putrescine, cadaverine, spermidine, serotonin, tryptamine, agmatine – and, flavonoids have suspected relevance for migraines and this implies that ethanol seems not to be the main culprit for the headaches [2].

Abstract:
Background:
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). The crucial role of diamine oxidase and histamine in immune balance has been documented in different studies and experiments both on MS patients and on experimental allergic encephalomyelitis (EAE). In this regard, we aimed to measure the level of histamine and diamine oxidase in the serum of MS patients.
Methods:
A total number of 50 relapsing-remitting MS (RRMS) patients and 41 age and sex matched controls were enrolled in this study. Assessments of serum levels of histamine and diamine oxidase enzyme were performed using enzyme-linked immune sorbent assay (ELISA). Results: The serum levels of histamine and diamine oxidase in RRMS patients were lower than healthy controls (P-value = 0.00, for both).
Conclusion:
Our research team found significant low levels of histamine and diamine oxidase in RRMS patients; however the pathogenesis of this issue was unclear.

Abstract
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. This study aimed to review the existing data on histamine and other biogenic amine contents in nonfermented plant-origin foods, as well as on their origin and evolution during the storage or culinary process. The only plant-origin products with significant levels of histamine were eggplant, spinach, tomato, and avocado, each showing a great variability in content. Putrescine has been found in practically all plant-origin foods, probably due to its physiological origin. The high contents of putrescine in certain products could also be related to the triggering of the symptomatology by enzymatic competition with histamine. Additionally, high spermidine contents found in some foods should also be taken into account in these diets, because it can also be metabolized by DAO, albeit with a lower affinity. It is recommended to consume plant-origin foods that are boiled or are of maximum freshness to reduce biogenic amine intake.

Abstract
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. Our aim was to determine the intestinal bacterial composition in patients with proven histamine intolerance in comparison to other food intolerances and healthy controls. A total of 64 participants were included in the study, encompassing 8 patients with histamine intolerance (HIT), 25 with food hypersensitivity (FH), 21 with food allergy and 10 healthy controls (HC). All participants underwent blood testing for total and food-specific immunoglobulin E, plasma histamine and DAO serum activity. Stool samples were used to analyze stool histamine and zonulin levels and bacterial composition by 16s rRNA sequencing. No significant differences in stool histamine levels were observed, but HIT patients showed elevated levels of stool zonulin. Microbiota analysis revealed increased levels of Proteobacteria (5.4%) and a significantly reduced alpha-diversity in the HIT group (P = 0.019). On family level, HC showed a significantly higher abundance of Bifidobacteriaceae compared to other study groups (P = 0.005), with lowest levels in the HIT group (P = 0.036). Also significantly reduced abundances of the genera Butyricimonas (P = 0.026) and Hespellia (P = 0.025) were observed in the HIT patients, whereas Roseburia were significantly elevated (P = 0.021). We concluded that the altered occurrence of Proteobacteria and Bifidobacteriaceae, reduced alpha-diversity as well as elevated stool zonulin levels suggest a dysbiosis and intestinal barrier dysfunction in histamine intolerant patients, which in turn may play an important role in driving disease pathogenesis.

Abstract
A functional mini protein can be developed by miniaturising its size. The minimisation technique provides an excellent model system for studying native enzymes, especially in creating an alternative novel biocatalyst. Miniaturised proteins may have enhanced stability, a crucial characteristic for large-scale production and industrial applications. In this study, a huge enzyme molecule, known as diamine oxidase (DAO, comprising 700 amino acids), was selected to undergo the process.

Abstract
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. Calculated with all 101 patients we found an increase of serum DAO values due to a HRD. In the 63 patients that completed the questionnaire, we found that 50 patients had improvement of symptoms or no continuing symptoms. A significant increase of serum DAO levels was found in the patients with strict and occasional diet compliance. Therefore, we demonstrate that a HRD is not only improving symptoms in HIT, but is causing an increase in serum DAO values that correlates with the degree of diet compliance.

Introduction:
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.
Objectives:
To assess the effectiveness of a low-histamine diet plus a DAO enzyme supplement on the remision of migraine in subjects with DAO deficiency.
Methods:
An intervention study was carried out in 212 individuals with a migraine diagnosis by a neurologist according to the International Classification of Headache Disorders and wih DAO deficiency (DAO <80 HDU/ml). Subjects followed a 3-month low-histamine diet based on the exclusion of foods considered rich in histamine or other biogenic amines and usually related to the onset of HI symptoms, such as fermented products (cheese, dry-fermented sausage, wine, beer), semi-preserved and canned fish, shellfish, certain fruits and vegetables (spinach, tomato, egg-plant, avocado, citrus, bananas, strawberries, pineapple, nuts) and chocolate. A DAO supplement was administrered before break-fast, lunch and dinner. Outcomes assessed were duration and number of attacks and perception of pain intensity with a score-scale fom 0 (absence) to 10.
Results:
Most subjects showed and improvement in migraines after the 3-month treatment: 34.9% reported complete remission and another 35.8% had a reduced number of migraines episodes per month of less duration and pain intensity. The treatment was less successful in 29.3% of patients. On average, when comparing baseline and final values after treatment, all outcomes were significantly reduced: 8 to 2 attacks per month, 24 to 3 hours of pain and 8 to 4 in pain intensity scoring.
Conclusions:
A low-histamine diet supplemented with the DAO enzyme for three months was useful in reducing the number of attacks, duration and intensity of pain in migraineous patients with DAO deficiency.

Introduction:
The use of exogenous diamine oxidase (DAO) enzyme has been recently postulated as a potential strategy for the treatment of histamine intolerance, a disorder in the homeostasis of histamine caused by a reduction of its intestinal degradation. Dietary supplements based on gastro-resistant encapsulated porcine kidney protein extract ara available on the market to reduce the symptoms of this intolerance. Although with scarce scientific research, there are some references about the potential of pea seedlings as a source of DAO.
Objectives:
To study the capacity of legumes and their sprouts to reduce histamine in vitro and evaluate the influence of different growing conditions on this enzymatic activity. If confirmed, legumes could become and advantageous alternative to porcine DAO enzyme from a productive and sustainable perspective.
Methods:
In vitro DAO activity was measured through and enzymatic assay and the subsequent analysis of remaining histamine by UHPLC-FL. Analysed samples were both raw pulses and prouts of lentils, beans (white, red and black), broad beans, peas, chickpeas and soy.

Abstract
BACKGROUND:
Acute-on-chronic hepatitis B liver failure (ACHBLF) has high 1-month mortality but it is difficult to predict. This present study was aimed to determine the diagnostic value of plasma diamine oxidase (DAO) in predicting the 1-month mortality of ACHBLF.
METHODS:
A total of 106 consecutive newly diagnosed ACHBLF patients were retrospectively collected. The plasma expression of DAO was determined using enzyme-linked immunosorbent assay (ELISA).
RESULTS:
The plasma DAO level of survivals [14.0 (7.1; 26.5) ng/mL] was significantly lower than the nonsurvivals [58.6 (32.5; 121.3) ng/mL, P < .001]. The plasma DAO level, hepatic encephalopathy, spontaneous bacterial peritonitis and model for end-stage liver disease (MELD) score were independent factors associated with the 1-month mortality for ACHBLF. The cut-off point of 15.2 ng/mL for plasma DAO level with sensitivity of 95.45%, specificity of 62.5%, 22.6 for MELD score with sensitivity of 90.91%, specificity of 67.5%, 0.07 for DAO plus MELD with sensitivity of 87.88%, specificity of 80% were selected to discriminate 1-month morality of ACHBLF. Furthermore, DAO plus MELD score showed high AUROC than MELD score for predicting 1-month (0.916 vs. 0.843, P < .01).
CONCLUSIONS:
The plasma DAO level plus MELD > 0.07 predicts poor 1-month mortality of ACHBLF.
