Kettner L, Seitl I, Fischer L. Evaluation of porcine diamine oxidase for the conversion of histamine in food-relevant amounts. J Food Sci 2020; 85:843-852. [PMID: 32090335 DOI: 10.1111/1750-3841.15069] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Revised: 01/10/2020] [Accepted: 01/10/2020] [Indexed: 11/29/2022]
Abstract
Histamine exists in a multitude of foods and displays an emerging role within food intolerances. Our aim was to identify the activity of porcine diamine oxidase (DAO) required for the in vitro degradation of histamine amounts that are found in typical meals containing histamine (75 mg, equaled 150 mg/L). Furthermore, we investigated an actual dietary supplement that is commercially available for histamine intolerant individuals for its histamine reduction capability. Kinetic investigations of porcine DAO showed a substrate inhibition by histamine concentrations greater than 56 mg/L (0.5 mM). The stability of free porcine DAO was tested in a fed state simulated intestinal fluid and exhibited a half-life period of around 19 min. A total of 50 nanokatal (nkat) free porcine DAO, which equaled the amount of enzyme isolated from around 100 g pig kidney, were necessary for the in vitro reduction of around 90% of the histamine. The dietary supplement that contains a pig kidney extract did not show DAO activity. Instead, the used histamine (0.75 mg) was apparently reduced due to the adsorption of histamine onto a capsule component by 18.9 ± 2.3% within 5 hr. Although the capsule preparation retained its overall structure and shape for at least 90 min in simulated gastric fluid, the apparent histamine reduction was significantly reduced to 12.1 ± 2.3% (P ≤ 0.05). In conclusion, an alternative to the pig kidney DAO or an improved capsule preparation is needed to ensure an adequate supplementation for histamine-intolerant humans. PRACTICAL APPLICATION: Histamine intolerance is an emerging issue in our society and the intolerance-related physiological symptoms are currently not reliably treatable due to a lack of scientific investigation. A commercially available dietary supplement for histamine intolerance does not fulfil the requirements for a satisfactory histamine reduction in intolerant humans. The activity of the histamine degrading enzyme diamine oxidase, required for a satisfactory histamine degradation, is by far higher than the theoretical amount apparently given in the dietary supplement. With this knowledge, it is obvious that improved food supplements must be developed to help histamine intolerant humans.

Abstract
The primary β-globin gene mutation that causes sickle cell disease (SCD) has significant pathophysiological consequences that result in hemolytic events and the induction of the inflammatory processes that ultimately lead to vaso-occlusion. In addition to their role in the initiation of the acute painful vaso-occlusive episodes that are characteristic of SCD, inflammatory processes are also key components of many of the complications of the disease including autosplenectomy, acute chest syndrome, pulmonary hypertension, leg ulcers, nephropathy and stroke. We, herein, discuss the events that trigger inflammation in the disease, as well as the mechanisms, inflammatory molecules and cells that propagate these inflammatory processes. Given the central role that inflammation plays in SCD pathophysiology, many of the therapeutic approaches currently under pre-clinical and clinical development for the treatment of SCD endeavor to counter aspects or specific molecules of these inflammatory processes and it is possible that, in the future, we will see anti-inflammatory drugs being used either together with, or in place of, hydroxyurea in those SCD patients for whom hematopoietic stem cell transplants and evolving gene therapies are not a viable option.

Abstract
Platelet adhesion, activation, and aggregation are essential for primary hemostasis, but are also critically involved in the development of acute arterial thrombotic occlusion. Stimulation of the collagen receptor glycoprotein VI (GPVI) leads to phospholipase Cγ2-dependent inositol triphosphate (IP3) production with subsequent platelet activation, due to increased intracellular Ca2+ concentration ([Ca2+]i). Although tricyclic antidepressants have been shown to potentially impair platelet activation, nothing is hitherto known about potential effects of the tricyclic antidepressant doxepin on platelet Ca2+ signaling and thrombus formation. As shown in the present study, doxepin significantly diminished the stimulatory effect of GPVI agonist collagen-related peptide (CRP) on intracellular Ca2+ release as well as subsequent extracellular Ca2+ influx. Doxepin was partially effective by impairment of CRP-dependent IP3 production. Moreover, doxepin abrogated CRP-induced platelet degranulation and integrin αIIbβ3 activation and aggregation. Finally, doxepin markedly blunted in vitro platelet adhesion to collagen and thrombus formation under high arterial shear rates (1,700-s). In conclusion, doxepin is a powerful inhibitor of GPVI-dependent platelet Ca2+ signaling, platelet activation, and thrombus formation.

Abstract
Both the treatment of patients with allergic diseases and the study of allergic disease mechanisms depend on a wide variety of assays that in various ways assess the presence and function of IgE antibody. The study of allergic diseases could benefit from the study of its 2 principle cellular participants, mast cells and basophils, but the basophil is more accessible than mast cells for ex vivo studies. Its functionality is tested by using 2 predominant methodologies: the secretion of mediators of allergic inflammation and the expression of proteins on the plasma membrane after stimulation. Each approach has benefits. There are also many operational details to consider regardless of which general approach is taken, and proper interpretation of the methods requires a good understanding of the reagents used and the receptors expressed on basophils and a detailed understanding of the factors regulating aggregation of cell-surface IgE.

Abstract
We aimed to clarify the disability progression and platelet aggregative function in atopic myelitis (AM). Seventeen AM patients and 35 healthy controls were subjected to clinico-allergological evaluations and glycoprotein IIb/IIIa (GP IIb/IIIa) measurements using a VerifyNow assay system. In AM patients, the disease duration had significant positive correlations with the Kurtzke Expanded Disability Status Scale scores and Sensory Functional Scale scores. The GP IIb/IIIa values were significantly higher in AM patients than in controls as well as in females compared with males. AM is essentially a progressive disease affecting the sensory system, and involves an increased platelet aggregative function.

Abstract
A sixty-four year old man with a past history of hypercholesterolemia, asthma, food allergy, epilepsy and myocardial infarction was admitted to the emergency department because of a generalized erythema, nausea, vomiting, and chest pain after taking an oral dose of amoxicillin. Electrocardiography showed ST segment elevation in anterior leads. After coronary angiography, type 2 variant of Kounis syndrome was diagnosed. We present the first case of oral amoxicillin induced Kounis syndrome in an asthmatic patient with severe anaphylactic shock. The present report also shows that atopic people expressing an amplified mast cell degranulation may have more serious hemodynamic decompensation during hypersensitivity reactions. Case selective mast cell surface membrane stabilization should be considered a potential therapeutic strategy for people with food induced allergy, for atopic patients and for patients who have already experienced a first Kounis syndrome.

Abstract
Inflammatory mediators including histamine, neutral proteases, arachidonic acid products, platelet activating factor and a variety of cytokines and chemokines are increased in blood or urine in both allergic episodes and acute coronary syndromes. The release of mediators during allergic insults has been incriminated to induce coronary artery spasm and/or atheromatous plaque erosion or rupture. A common pathway between allergic and non-allergic coronary syndromes seems to exist. Today, there is evidence that mast cells not only enter the culprit region before plaque erosion or rupture but they release their contents before an actual coronary episode. Kounis syndrome is the concurrence of acute coronary syndromes with conditions associated with mast cell activation including allergic or hypersensitivity and anaphylactic or anaphylactoid insults. It is caused by inflammatory mediators released through mast cell activation. Kounis syndrome, as consequence, of the above pathophysiologic association is regarded as nature's own experiment and magnificent natural paradigm showing novel way in an effort to prevent acute coronary syndromes. Drugs and natural molecules which stabilize mast cell membrane and monoclonal antibodies that protect mast cell surface could emerge as novel therapeutic modalities capable to prevent acute coronary and cerebrovascular events.

Abstract
Short-term increases in particulate air pollution are associated with increased incidence of cardiovascular events. Previously, we showed that intratracheally instilled diesel exhaust particles (DEPs) are prothrombotic. Here, we investigated the time course and the mechanisms. At 1, 6, and 24 hours after instillation of 50 microg DEPs per hamster, the mean size of in vivo-induced and quantified venous thrombosis was increased by 480%, 770%, and 460%, respectively. Platelets activation in blood was confirmed by a shortened closure time in the platelet function analyzer (PFA-100). In bronchoalveolar lavage, neutrophils and histamine levels were increased at all time points. In plasma, histamine was increased at 6 and 24 hours but not at 1 and 3 hours. Pretreatment with a histamine H1-receptor antagonist (diphenhydramine, 30 mg/kg intraperitoneally) abolished the DEP-induced neutrophil influx in bronchoalveolar lavage at all time points. However, diphenhydramine pretreatment did not affect DEP-induced thrombosis or platelet activation at 1 hour, whereas both were markedly reduced at 6 and 24 hours. In conclusion, pulmonary inflammation and peripheral thrombosis are correlated at 6 and 24 hours, but at 1 hour, the prothrombotic effects do not appear to result from pulmonary inflammation but possibly from the blood penetration of DEP-associated components or by DEP particles themselves.

Abstract
Myocardial ischemia activates cardiac spinal afferents that mediate chest pain and excitatory reflex cardiovascular responses. Platelets are activated during myocardial ischemia and release 5-hydroxytryptamine, which stimulates abdominal spinal afferents. This study investigated the role of activated platelets in excitation of cardiac spinal afferents during ischemia. Platelet-rich plasma (PRP) and platelet-poor plasma (PPP) were obtained from cats and incubated with collagen (2 mg/ml) or thrombin (5 U/ml). We observed reduction of platelets in PRP indicative of platelet activation by collagen and thrombin, respectively. Activity of single-unit, ischemia-sensitive cardiac spinal afferents was recorded from the left sympathetic chain in anesthetized cats. Injection of 1.5 ml PRP + collagen (activated platelets) into the left atrium (LA) stimulated 12 of 13 cardiac afferents. PRP + saline (nonactivated platelets, LA) and PPP + collagen did not alter activity of these afferents. PRP + thrombin (1.5 ml, LA) stimulated eight of nine other cardiac afferents, whereas PPP + thrombin did not stimulate any of the nine afferents. Antiplatelet immune serum (1 ml/kg iv) significantly decreased circulating platelets as well as neutrophils (polymorphonuclear leukocytes, PMNs) in eight other cats, and in each animal, attenuated the ischemia-related increase in activity of cardiac afferents. Conversely, responses of five separate cardiac afferents to ischemia were not diminished after treatment with anti-PMN immune serum when concentration of circulating platelets was maintained by infusion of donated PRP despite the decrease in circulating PMNs. These data indicate activated platelets stimulate ischemia-sensitive cardiac spinal afferents and contribute to activation of these afferents during ischemia.

Abstract
Second generation antihistamines are recognised as being highly effective treatments for allergy-based disease and are among the most frequently prescribed and safest drugs in the world. However, consideration of the therapeutic index or the benefit/risk ratio of the H1 receptor antagonists is of paramount importance when prescribing this class of compounds as they are used to treat non-life threatening conditions. There are many second generation antihistamines available and at first examination these appear to be comparable in terms of safety and efficacy. However, the newer antihistamines in fact represent a heterogeneous group of compounds, having markedly differing chemical structures, adverse effects, half-life, tissue distribution and metabolism, spectrum of antihistaminic properties, and varying degrees of anti-inflammatory effects. With regard to the latter, there is growing awareness that some of these compounds might represent useful adjunct medications in asthma therapy. In terms of safety issues, the current second generation grouping includes compounds with proven cardiotoxic effects and others with the potential for adverse drug interactions. Moreover, some of the second generation H1 antagonists have given cause for concern regarding their potential to cause a degree of somnolence in some individuals. It can be argued, therefore, that the present second generation grouping is too large and indistinct since this was based primarily on the concept of separating the first generation sedating compounds from nonsedating H1 antagonists. Although it is too early to talk about a third generation grouping of antihistamines, future membership of such a classification could be based on a low volume of distribution coupled with a lack of sedating effects, drug interactions and cardiotoxicity.
