Associations Between Migraine, Celiac Disease, Non-Celiac Gluten Sensitivity and Activity of Diamine Oxidase
Background and pilot study: Recent reports reveal a close relationship between migraine and gastrointestinal disorders (GI), such as celiac disease (CD) and non-celiac gluten sensitivity (NCGS). CD is a genetic autoimmune disorder, which affects the mucosa of the small intestine. Gluten, found in various grains, not only plays a major role in the pathophysiology of CD and NCGS, but also aggravates migraine attacks. Another common food component, which can induce migraine headaches, is histamine. Diamine oxidase (DAO) is an enzyme, which degrades histamine. Reduced activity of DAO means reduced histamine degradation, which can cause histamine build-up and lead to various symptoms, including headaches and migraine. In this paper we propose a hypothesis, that in pathogenesis of migraine, low serum DAO activity is related to CD and NCGS. We also conducted our own pilot study of 44 patients with severe migraine in efforts to evaluate the co-presence of decreased serum DAO activity and celiac disease/NCGS in patients. 44 consecutive migraine patients were divided into 2 groups: decreased DAO activity (group 1; n = 26) and normal DAO activity (group 2; n = 18). All patients were screened for celiac disease. The diagnosis of NCGS was made after exclusion of CD, food allergies and other GI disorders in the presence of gluten sensitivity symptoms. Furthermore, dietary recommendations were given to all participants and their effects were assessed 3 months after the initial evaluation via the MIDAS (Migraine Disability Assessment) questionnaire.
Results and conclusions: Only 1 patient fit the criteria for celiac disease, rendering this result inconclusive. Pathological findings of the remainder of patients were attributed to NCGS (n = 10). 9 of 10 patients with NCGS belonged to the decreased serum DAO activity group (group 1; n = 26), suggesting a strong relationship between reduced serum DAO activity and NCGS. MIDAS questionnaire revealed, that patients with decreased serum DAO activity were more severely impacted by migraine than those with normal DAO activity, and this remained so after our interventions. Dietary adjustments significantly reduced the impact of migraine on patients’ daily activities after 3 months in both groups. We argue, that migraine, celiac disease and NCGS may benefit from treatment with a multidisciplinary approach, involving neurologists, gastroenterologists and dietitians.

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.

Introduction: Histamine is the major mediator of IgE- and non-IgE-mediated allergic reactions upon allergen or
hapten contact. Reduced histamine degradation capacity was associated with atopic eczema as well as with nonimmunological
histamine intolerance. Higher blood serum histamine level concomitant with decreased intestinal
diamine oxidase activity were observed in patients with food allergy.
Aim: To evaluate the relationship between patients’ blood diamine oxidase (DAO) activity/histamine status and
their reactivity to time-resolved histamine skin prick test in respect to vulnerability to allergic diseases.
Material and methods: Fifty-three patients were examined with skin prick tests (SPT) and patch tests for suspected
presence of either IgE- or non-IgE-mediated allergy. All individuals were skin prick tested with histamine and the
resolution of the wheal was monitored for 50 min. Blood DAO activity and histamine concentration were measured
with a radio-extraction radioimmunoassay.
Results: Time-resolved histamine skin prick testing revealed presence of wheals which were 35% larger in diameter
in 47% of examined subjects at 20 min of the test. These patients exhibited significantly compromised time-course
wheal resolution (wheal ≥ 3 mm at 50 min) compared to a group of patients with the normal-rate of wheal resolution
(wheal = 0 mm at 50 min). Within a group of subjects exhibiting impaired wheal resolution, 61% of patients
were diagnosed allergic compared to 50% in a group of patients with a normal rate of wheal resolution. Finally,
allergic patients were characterized by a significantly lower DAO activity and higher histamine content compared
to healthy subjects.
Conclusions: The results of this study indicate that patients with IgE- or non-IgE-mediated allergy are likely to
have low DAO blood activity and may concomitantly suffer from histamine intolerance. Furthermore, our results
suggest that allergic patients are more likely to develop an excessive SPT reaction. Our results emphasize caution
in interpretation of the SPT results in allergic patients with diagnosed histamine intolerance or histamine/DAO

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.
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).
Our research team found significant low levels of histamine and diamine oxidase in RRMS patients; however the pathogenesis of this issue was unclear.

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.

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.

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.
To assess the effectiveness of a low-histamine diet plus a DAO enzyme supplement on the remision of migraine in subjects with DAO deficiency.
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.
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.
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.

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.
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).
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).
The plasma DAO level plus MELD > 0.07 predicts poor 1-month mortality of ACHBLF.

Diamine oxidase (DAO) catabolizes and inactivates histamine, a key player in a wide range of invalidating conditions, such as migraine and chronic spontaneous urticaria (CSU). The highest expression of DAO occurs in the gastrointestinal tract, possibly to control the burden of histamine intake from food.
Here, we tested the hypothesis that a 30-day oral supplementation with DAO (1 capsule b.i.d., 15 min before a meal) could reduce the severity of CSU as estimated by the 7-Day Urticaria Activity Score (UAS-7). The study was designed as a double-blind, placebo-controlled, crossover investigation of 22 patients with CSU incompletely controlled by first-line antihistamine therapy.
Twenty patients completed the study. Supplemental therapy with DAO caused a 3.8 ± 1.2 point mean ± SEM UAS-7 score reduction in patients with low serum DAO levels at time 0 (p = 0.041 compared to placebo). The degree of UAS-7 improvement was inversely correlated with the levels of basal DAO (p = 0.019). Patients receiving DAO supplementation were able to slightly reduce their daily antihistamine dose (p = 0.049).
These data suggest that DAO may be involved in the pathogenic cascade of CSU and that DAO supplementation could be effective for symptom relief in patients with low DAO levels in serum.

Histamine intolerance is thought to trigger manifold clinical symptoms after ingesting histamine-rich food due to reduced activity of diamine oxidase (DAO). No study has hitherto systematically assessed daily fluctuations of histamine levels and DAO activities in symptomatic patients. The aim of the study was to investigate the presence of histamine intolerance, to therefore establish day profiles of histamine levels and DAO activities, and to compare the results between patients with suspected histamine intolerance, food allergy and healthy controls.
We determined day profiles of histamine plasma levels and DAO serum activities in 33 patients with suspected histamine intolerance, in 21 patients with proven food allergy and in 10 healthy control patients. Clinical symptoms, food intolerances and further clinical and laboratory chemical parameters were evaluated.
Twenty-four percent (8 of 33) suspected histamine-intolerant patients showed elevated histamine levels during the day. That might be caused by constantly and significantly reduced DAO activities in these patients compared to food-allergic and control patients. The remaining 25 patients presented normal histamine levels and DAO activities, but an increased prevalence of multiple food intolerances compared to the other subgroup of suspected histamine-intolerants. There was no correlation between subjective complaints and serological histamine parameters in patients with suspected histamine intolerance.
We determined by daily profiling that decreased DAO activities correlated with elevated histamine levels in a subgroup of suspected histamine-intolerants. This finding discriminates these patients from food intolerant individuals with similar clinical symptoms and strongly suggests the presence of histamine intolerance.
