Abstract
PURPOSE OF REVIEW Mast cell activation syndrome is defined by severe, episodic, and recurrent symptoms induced by mast cell mediators with objective measurement of increase in biomarkers of mast cell activation and treatment response with mast cell therapies. Increase in serum tryptase from baseline during a mast cell activation episode is currently the most accepted biomarker measurement of mast cell release. However, during symptomatic episodes, serum tryptase can be difficult to obtain as it is a venipuncture procedure. Other objective measures of mast cell activation are needed to complement serum tryptase. RECENT FINDINGS Urine mast cell mediators can be collected at home and are non-invasive tests. There is emerging evidence for the utility of urine mast cell mediators including histamine, cysteinyl leukotrienes, and prostaglandins in the diagnosis of mast cell activation syndrome. In this review, clinically available urine mast cell mediators will be discussed including N-methylhistamine, leukotriene E4, and 2,3-dinor-11beta-prostaglandin F2 alpha. We discuss the rationale for the use of these urine mast cell mediators and examine the studies analyzing their performance for identifying mast cell activation.

Metabolitic profiling of amino acids in paraquat-induced acute kidney injury. Clin Exp Nephrol 2019; 23:474-483. [PMID: 30859350 DOI: 10.1007/s10157-019-01702-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2018] [Accepted: 05/19/2018] [Indexed: 01/07/2023]
Abstract
BACKGROUND The herbicide paraquat (1, 1'-dimethyl-4, 4'-bipyridylium dichloride; PQ) is a poison well-known to cause delayed mortality due to acute kidney injuries (AKI). This study examines the changes in serum amino acids (AAs) metabolite profiles as surrogate markers of renal cell metabolism and function after paraquat poisoning. METHODS To identify the metabolic profiling of free serum AAs and its metabolites, serum from 40 paraquat-poisoned patients with or without AKI is collected. LC-MS/GC-MS is performed to analyze AA molecules. A Cox proportional hazard model was used to assess for incidence of AKI. Receiver operating characteristic (ROC) curve is applied to evaluate AKI occurrence and prognosis. RESULTS A total of 102 serum AAs and its metabolites were identified. Compared with non-AKI patients, 37 varied significantly in AKI patients. The univariate Cox proportional hazard model analysis revealed that the estimated PQ amount, plasma PQ concentration, urine PQ concentration, APACHE, SOFA scores and 16 amino acids correlated with the incidence of AKI. Further analyses revealed that 3-methylglutarylcarnitine, 1-methylimidazoleacetate, and urea showed higher cumulative hazard ratios for the occurrence of AKI during follow-up (P < 0.05). The area under the curve (AUC) of 3-methylglutarylcarnitine, 1-methylimidazoleacetate and urea were 0.917, 0.857, 0.872, respectively. CONCLUSION 3-methylglutarylcarnitine, 1-methylimidazoleacetate and urea were associated with AKI in patients with paraquat intoxication.

Excretion of urinary histamine and N-tele methylhistamine in patients with gastrointestinal food allergy compared to non-allergic controls during an unrestricted diet and a hypoallergenic diet. BMC Gastroenterol 2015; 15:41. [PMID: 25888445 PMCID: PMC4389952 DOI: 10.1186/s12876-015-0268-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2014] [Accepted: 03/11/2015] [Indexed: 12/28/2022] Open
Abstract
Background Patients with gastrointestinal food allergy are characterised by increased production of mast cell derived mediators upon allergen contact and present often with unspecific symptoms. The aim of this study was to evaluate urinary histamine and methylhistamine excretion in patients with food allergy and to compare their values with food-tolerant controls. Methods In a retrospective case control study the urinary excretion parameters were analysed from 56 patients (40.9, 19 – 58 years) in whom later food challenge tests confirmed food allergy. During their diagnostic work-up urine was collected during a 12-h period under an unrestricted diet with staple foods and a hypoallergenic potato-rice-diet (each 2 days). Healthy controls underwent the same diet types to define normal excretion parameters. Urinary histamine and n-methylhistamine were determined by ELISA or tandem mass spectrometry, respectively, and were expressed as median (25 – 75% range, μg/mmol creatinine x m2BSA). Results During unrestricted diet urinary histamine was significantly higher in gastrointestinal food allergy than healthy controls (1.42, 0.9 – 2.7 vs 0.87, 0.4 – 1.3; p < 0.0001), while the difference between both groups became marginal during potato-rice diet (1.30, 0.7 – 2.1 vs 1.05, 0.5 – 1.5; p = 0.02). N-methylhistamine was found to be significantly elevated in gastrointestinal food allergy both during unrestricted diet (7.1, 5.0 – 11.2) and potato-rice diet (5.7, 3.7 – 8.7) compared to controls (p < 0.0001). Interestingly, urinary methylhistamine excretion (p < 0.004) and clinical symptom score (p < 0.02) fell significantly when the diet was switched from unrestricted to hypoallergenic food, but was not correlated with symptom scores. Conclusions In gastrointestinal food allergy significantly higher levels of urine histamine and methylhistamine excretion were found under unrestricted diet, reflecting an increased secretion of histamine due to offending foods. Measurement of urinary n-methylhistamine levels may help to find out patients with increased histamine production and/or food-allergen induced clinical symptoms, respectively.

Abstract
Histamine intolerance results from a disequilibrium of accumulated histamine and the capacity for histamine degradation. Histamine is a biogenic amine that occurs to various degrees in many foods. In healthy persons, dietary histamine can be rapidly detoxified by amine oxidases, whereas persons with low amine oxidase activity are at risk of histamine toxicity. Diamine oxidase (DAO) is the main enzyme for the metabolism of ingested histamine. It has been proposed that DAO, when functioning as a secretory protein, may be responsible for scavenging extracellular histamine after mediator release. Conversely, histamine N-methyltransferase, the other important enzyme inactivating histamine, is a cytosolic protein that can convert histamine only in the intracellular space of cells. An impaired histamine degradation based on reduced DAO activity and the resulting histamine excess may cause numerous symptoms mimicking an allergic reaction. The ingestion of histamine-rich food or of alcohol or drugs that release histamine or block DAO may provoke diarrhea, headache, rhinoconjunctival symptoms, asthma, hypotension, arrhythmia, urticaria, pruritus, flushing, and other conditions in patients with histamine intolerance. Symptoms can be reduced by a histamine-free diet or be eliminated by antihistamines. However, because of the multifaceted nature of the symptoms, the existence of histamine intolerance has been underestimated, and further studies based on double-blind, placebo-controlled provocations are needed. In patients in whom the abovementioned symptoms are triggered by the corresponding substances and who have a negative diagnosis of allergy or internal disorders, histamine intolerance should be considered as an underlying pathomechanism.

Abstract
BACKGROUND Histamine is thought to be the main cause of adverse reactions to wines. OBJECTIVE The purpose of this study was to test the hypothesis that the level of histamine in wine affects the tolerance to wine in 16 subjects with wine intolerance. METHODS We performed a study to examine the effects of wine histamine content in 16 adults with wine intolerance. Each subject underwent 2 double-blind provocation tests with wine: 1 with a wine poor in histamine (0.4 mg/L), and 1 with a wine rich in histamine (13.8 mg/L). Blood was collected for histamine and methylhistamine RIAs at 0, 10, 30, and 45 minutes after ingestion of the wine. Methylhistamine and methylimidazolacetic acid (gas chromatography and mass spectrometry) were measured in urine 5 hours before and 5 hours after ingestion. RESULTS No significant differences in the occurrence of adverse reactions were noted after ingestion of either of the wines (McNemar test). At 10 minutes, a significant increase was observed in plasma histamine with histamine-poor wine. No significant changes (Wilcoxon test) were observed in the methylhistamine and methylimidazolacetic acid levels after ingestion of either histamine-poor or histamine-rich wine. CONCLUSION This study demonstrates that there is no correlation between the histamine content of wine and wine intolerance. The increase of plasma histamine levels at 10 minutes with histamine-poor wine suggested the role of a histamine-releasing substance. The role of acetaldehyde is discussed.

Abstract
Urinary histamine and Ngamma-methylhistamine (1-MH), a histamine metabolite, are highly correlated with histamine in plasma. Therefore, allergic reactions can be examined by determination of histamine and 1-MH in urine. We separated histamine, 1-MH and Nalpha-methylhistamine (N-MH) by capillary electrophoresis with UV detection at 210nm, using borate buffer (pH 9) containing 100 mM SDS. The absolute detection limits were 200, 100 and 50 pg for histamine, 1-MH and N-MH, respectively. To purify histamine 1-MH and N-MH in urine, a silica cartridge was used. Recovery rates of histamine, 1-MH and N-MH in physiological saline were 90.0, 91.4 and 95.4%, respectively. We measured histamine and 1-MH levels in urine from a normal female volunteer before and after a meal, and a male bronchial asthma patient. The results showed clearly that the concentrations of histamine and its metabolite rose after eating or asthma attack. N-MH was not detected in the urine.

Abstract
BACKGROUND It is generally accepted that the early asthmatic response to inhaled allergen is a result of IgE-mediated mast cell activation. In contrast, the underlying mechanism of the late asthmatic response is much less clear. OBJECTIVE In order to investigate the pattern of mediator release during the early and late asthmatic responses to allergen, measurements of the urinary excretion of the mast cell markers 9alpha,11beta-PGF2 and Ntau-methylhistamine were made. In addition, urinary levels of eosinophil protein X (EPX) and leukotriene E4 (LTE4) were measured. METHODS Twelve mild atopic asthmatics participated in the study. On the study day, pulmonary function was recorded at baseline and for 12 h after inhalation of allergen. Urine was collected prior to challenge and thereafter at 1 h intervals. Measurements of 9alpha, 11beta-PGF2 and LTE4 were made with enzyme-immunoassay, and levels of Ntau-methylhistamine and EPX were analysed with radioimmunoassay. RESULTS All subjects developed both an early and late phase airway response. Within 1 h of the early peak airway response, there was a significant increase in the urinary concentrations (AUC/h) of 9alpha, 11beta-PGF2 (49.3 +/- 9.2 to 142.5 +/- 49.2; P < 0.001) Ntau-methylhistamine (10.4 +/- 1.4 to 19.5 +/- 1.4; P < 0.001) and LTE4 (43.7 +/- 5.9 to 105.9 +/- 21.3; P < 0.001). Levels of all three mediators were also significantly increased above baseline during the LAR to 79.4 +/- 9.5 (P < 0.01), 19.8 +/- 1.9 (P < 0.001) and 85.6 +/- 10.4 (P < 0.001), respectively. Levels of EPX remained unchanged during the early and late responses (39.2 +/- 10.2 to 37.5 +/- 18.5, 33.9 +/- 6.8). CONCLUSIONS These results indicate that mast cell activation is a feature not only of the early but also the late asthmatic response. Finally, increased LTE4 supports the contribution of the leukotrienes to airway obstruction during both phases of the asthmatic response to allergen.
