Abstract: La intolerancia a la histamina (HIT) es un trastorno común asociado a la alteración del metabolismo de la histamina. No obstante, a menudo se diagnostica erróneamente como otras enfermedades debido a su falta de manifestaciones clínicas específicas. La HIT no cobró importancia hasta principios del siglo XXI. En esta revisión, nos centraremos en las investigaciones más recientes y en las manifestaciones clínicas de la HIT, incluidas sus manifestaciones en poblaciones especiales como la dermatitis atópica (DA) y la urticaria crónica (UC), así como los últimos conocimientos sobre su etiología y patogénesis. Además, exploraremos las estrategias de tratamiento más recientes para la HIT y el tratamiento de casos específicos.
Asociación entre Migraña, Celiaquía, Sensibilidad al Gluten no celíaca y Actividad de la Diamino Oxidasa
Antecedentes y estudio piloto: 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. El gluten, que se encuentra en varios cereales, no solo juega un papel importante en la fisiopatología de EC y NCGS, sino que también agrava los ataques de migraña. Otro componente alimenticio común, que puede inducir migrañas, es la histamina. La diamino oxidasa (DAO) es una enzima que degrada la histamina. La actividad reducida de DAO significa una degradación reducida de la histamina, que puede causar la acumulación de histamina y provocar diversos síntomas, incluidos dolores de cabeza y migraña. En este artículo proponemos una hipótesis, que en la patogénesis de la migraña, la baja actividad de DAO en suero está relacionada con EC y NCGS. También realizamos nuestro propio estudio piloto de 44 pacientes con migraña severa en un esfuerzo por evaluar la presencia conjunta de disminución de la actividad sérica de DAO y la enfermedad celíaca / NCGS en pacientes. Se dividieron 44 pacientes de migraña consecutivos en 2 grupos: actividad DAO disminuida (grupo 1; n = 26) y actividad DAO normal (grupo 2; n = 18). Todos los pacientes fueron examinados para detectar enfermedad celíaca. El diagnóstico de NCGS se realizó después de la exclusión de EC, alergias alimentarias y otros trastornos gastrointestinales en presencia de síntomas de sensibilidad al gluten. Además, se dieron recomendaciones dietéticas a todos los participantes y sus efectos se evaluaron 3 meses después de la evaluación inicial a través del cuestionario MIDAS (Evaluación de la discapacidad de la migraña).
Resultados y conclusiones: Solo 1 paciente cumple los criterios para la enfermedad celíaca, lo que hace que este resultado no sea concluyente. Los hallazgos patológicos del resto de pacientes se atribuyeron a NCGS (n = 10). 9 de 10 pacientes con NCGS pertenecían al grupo de actividad de DAO en suero disminuido (grupo 1; n = 26), lo que sugiere una fuerte relación entre la actividad de DAO en suero reducida y NCGS. El cuestionario MIDAS reveló que los pacientes con disminución de la actividad sérica de DAO se vieron más afectados por la migraña que aquellos con actividad normal de DAO, y esto siguió siendo así después de nuestras intervenciones. Los ajustes dietéticos redujeron significativamente el impacto de la migraña en las actividades diarias de los pacientes después de 3 meses en ambos grupos. Argumentamos que la migraña, la enfermedad celíaca y el NCGS pueden beneficiarse del tratamiento con un enfoque multidisciplinario, que involucra neurólogos, gastroenterólogos y dietistas.

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
Biogenic Amines in Plant-Origin Foods: Are they Frequently Underestimated in Low-Histamine Diets?
Foods 2018, 7(12), 205.
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.

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.

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.

A Histamine-Free Diet Is Helpful for Treatment of Adult Patients with Chronic Spontaneous Urticaria.
In adult patients with chronic urticaria (CU), the prevalence of food allergy is low compared to childhood patients. However, there are many patients who report food-related aggravation of CU, and some of them may have histamine intolerance.
The aim of this study was to evaluate the role of ingested histamine and to investigate the effect of a histamine-free diet in adult patients with CU.
Twenty-two adult patients with CU were enrolled. Foods with high amounts of histamine were prohibited to all patients for four weeks. The degree of severity of the urticaria was evaluated using the urticaria severity score (USS) and urticaria activity score (UAS). Plasma histamine levels and diamine oxidase (DAO) activity were determined and compared before (baseline) and after the histamine-free diet.
Twenty-two adult patients were recruited and completed four weeks of histamine-free diet. The USS and UAS scores each showed significant differences before and after the histamine-free diet (p=0.010, p=0.006). There was a significant reduction in plasma histamine level after the histamine free-diet, compared with baseline (p=0.010). However, DAO activity did not change after the histamine-free diet (p=0.165).
Our study suggested that ingested histamine might be related to CU severity and that a histamine-free diet is helpful for treatment of adult patients with CU.
A Popular myth – low-histamine diet improves chronic spontaneous urticaria – fact or fiction?

Chronic spontaneous urticaria (CsU) is a frequent dermatological disease that might last for months or years with high impact on quality of life. Known causes are autoreactive phenomena, infections or intolerances, rarely IgE-mediated allergies. One-third of CsU patients benefit from a low-pseudoallergen diet. Additionally, it is often discussed, that reducing histamine ingestion alone might improve clinical symptoms and quality of life in CsU patients despite the uncertain role of the histamine-degrading enzyme diamine oxidase (DAO).
Aim of this study was to investigate the impact of low-histamine diet on symptoms and quality of life in patients with CsU.
Patients suffering from CsU accompanied by gastrointestinal symptoms were included in the study. They underwent low-histamine diet for at least 3 weeks. During the whole study, urticaria activity score (UAS) was recorded daily in a patient’s diary. Quality of life was assessed during screening, baseline and post diet visits by completing questionnaires (DLQI and Cu-Q(2)oL). DAO activity was measured before and after elimination diet.
A total of 75% of the patients had a benefit from the low-histamine diet. Thirty-four of 56 patients (61%) reached the primary endpoint of the study, an improvement of UAS 4 of ≥3. Overall, a significant reduction from 9.05 to 4.23 points (P = 0.004) was achieved; the average reduction in a strongly affected subgroup was 8.59 points (P < 0.001). DAO activity remained stable.
Low-histamine diet is a therapeutically useful, simple and cost-free tool to decrease symptoms and increase quality of life in CsU patients with gastrointestinal involvement. Further research is needed to understand the role of diamine oxidase.
