Histamine poisoning results from the consumption of foods, typically certain types of fish and cheeses, that contain unusually high levels of histamine. Spoiled fish of the families, Scombridae and Scomberesocidae (e.g. tuna, mackerel, bonito), are commonly implicated in incidents of histamine poisoning, which leads to the common usage of the term, "scombroid fish poisoning", to describe this illness. However, certain non-scombroid fish, most notably mahi-mahi, bluefish, and sardines, when spoiled are also commonly implicated in histamine poisoning. Also, on rare occasions, cheeses especially Swiss cheese, can be implicated in histamine poisoning. The symptoms of histamine poisoning generally resemble the symptoms encountered with IgE-mediated food allergies. The symptoms include nausea, vomiting, diarrhea, an oral burning sensation or peppery taste, hives, itching, red rash, and hypotension. The onset of the symptoms usually occurs within a few minutes after ingestion of the implicated food, and the duration of symptoms ranges from a few hours to 24 h. Antihistamines can be used effectively to treat this intoxication. Histamine is formed in foods by certain bacteria that are able to decarboxylate the amino acid, histidine. However, foods containing unusually high levels of histamine may not appear to be outwardly spoiled. Foods with histamine concentrations exceeding 50 mg per 100 g of food are generally considered to be hazardous. Histamine formation in fish can be prevented by proper handling and refrigerated storage while the control of histamine formation in cheese seems dependent on insuring that histamine-producing bacteria are not present in significant numbers in the raw milk.

Thirty-six patients suffering from disseminated epithelial tumors under treatment with Cisplatin alone or in combination with Vindesine entered a randomized, double-blind, cross-over study comparing the antiemetic activity of low-dose IV Metoclopramide (total dose: 0.8 mg/kg) with that of a combination of Metoclopramide (same schedule) plus Nortriptyline (2 X 50 mg PO) plus Thiethylperazine (3 X 10 mg IV). This combination was designed in an attempt to act simultaneously on gastrointestinal motility and neuroreceptors at central emetic pathways (Dopamine D-2, Histamine H-1 and muscarinic cholinergic). The antiemetic combination significantly reduces the median number of emetic episodes (p less than 0.01), the median volume of vomiting (p less than 0.01) and the median time of emesis (p less than 0.01) when compared with Metoclopramide alone and was also preferred by a significant number of patients (p = 0.0001) after passing through both antiemetic treatment arms being compared.

Cefotiam (CTM) is one of the most popular cephem antibiotics in Japan. Recently we experienced two cases of nurses with CTM-induced contact anaphylaxis. When they were preparing drip infusions of antibiotics or working around other nurses doing so, they suddenly fell into shock with other symptoms such as flushing, urticaria, abdominal distress, vomiting, dyspnoea and/or loss of consciousness. The symptoms never occurred after they avoided exposure to CTM. Passive cutaneous or open patch tests were positive for CTM. Histamine release was induced by CTM from washed leucocytes. RAST analysis using CTM-human serum albumin-coupled discs showed high % RAST count, suggesting that these reactions were mediated by IgE antibodies. A RAST inhibition test suggested that the methyl-thiotetrazole side-chain was the main antigenic determinant. Both patients had hand dermatitis that had appeared preceding the episodes of anaphylaxis. Although the dermatitis had been resistant to treatments, it also disappeared after they avoided exposure to CTM. It seemed likely that it was also induced or exacerbated by CTM and facilitated the penetration of CTM to cause anaphylaxis. The literature is also reviewed.

Interleukin-3 treatment of juvenile rhesus monkeys elicits a dose- and time-dependent syndrome that includes urticaria, palpable lymph nodes, splenomegaly, thrombocytopenia, anemia, vomiting, diarrhea, intestinal bleeding, edema, and arthritis, apart from a strong stimulation of hemopoiesis. Arthritis was found to occur significantly more often in animals expressing the major histocompatibility complex alleles B9 and Dr5. Histological analysis revealed an abundance of mast cells in urticaria and, to a lesser extent, in lungs and synovia of arthritic joints. Active osteoclasts were abundant in ribs and arthritic joints. Extramedullary hemopoiesis was encountered in liver, spleen, and kidneys. The spleen showed deposits of hemosiderin, and in the liver, Kupffer cells were loaded with iron, indicating enhanced turnover of hemoglobin. Lymph nodes and bone marrow showed macrophages involved in hemophagocytosis, which probably contributed to the development of anemia and thrombopenia. Biochemical parameters in sera were indicative of parenchymal liver damage, with cholestasis and increased erythrocyte destruction. The side effects were strongly reduced in monkeys subjected to total body irradiation just before interleukin-3 treatment. Histamine antagonists were not significantly effective in preventing side effects, which is explained by the perpetual stimulation of basophilic granulocytes by exogenous interleukin-3. The nature of the side effects indicates that interleukin-3 may be involved in the pathogenesis of acute type hypersensitivity reactions and arthritis.

Histamine H1-receptors are involved in the development of the symptoms and signs of motion sickness, including emesis. On provocative motion stimulus, a signal for sensory conflict activates the histaminergic neuron system, and the histaminergic descending impulse stimulates H1-receptors in the emetic center of the brain stem. The histaminergic input to the emetic center through H1-receptors is independent of dopamine D2-receptors in the chemoreceptor trigger zone and serotonin 5HT3-receptors in the visceral afferent, which are also involved in the emetic reflex. Antihistamines block emetic H1-receptors to prevent motion sickness. Acetylcholine muscarinic receptors are involved in the generation of signals for sensory conflict. Anti-cholinergic drugs prevent motion sickness by modifying the neural store to facilitate the acquisition of habituation to provocative motion.

The first indication that histamine might be important in the functioning of the brain was the finding that the centrally penetrating histamine H1 antagonists had marked sedative properties. Subsequently with the development of more specific compounds and drugs for the H1, H2 and H3 receptors a greater understanding of the neurotransmitter/modulator role of histamine in the CNS has been possible. Histamine is now associated with wakefulness, suppression of seizures, hypothermia and emesis. The histamine H1 antagonists have been shown to potentiate opioid-induced analgesia, and modify eating and drinking patterns as well as endocrine secretions from the pituitary gland. Additionally, clinically useful antidepressants have been shown to inhibit histamine-sensitive adenylate cyclase from the mammalian brain. Recently, a possible role for both histamine H1 and H2 receptors in schizophrenia has been reported. As more specific and centrally-penetrating histaminergic compounds are developed, so the roles of histamine as a neurotransmitter/modulator in the brain will be better understood.

Numerous undesirable reactions to alcoholic beverages, foods, drugs and other substances are characterized by allergy-like signs and symptoms and yet show unambiguously negative allergy test results. Such persons should be assessed for evidence of histamine intolerance caused by histamine overload and/or diamine oxidase deficiency. Diamine oxidase is the main histamine degrading enzyme with a predominantly gut activity. This would explain why nutritional allergies are often primarily suspected. The clinical evidence for histamine intolerance is based on chronic headache, diarrhoea, vomiting, flush, urticaria, asthma-like symptoms, rhinitis and others. Histamine restricted food, supported if necessary by H1 antihistamine blockade are simple but highly efficacious measures as shown by us in large patient groups. Intolerance to red wine probably is the most outstanding clinical characteristic and a directed question must be included into any allergy history in order to avoid missing a very major diagnostic spectrum with good therapeutic maneuverability.

We report a case of bullous mastocytosis in a 30-month-old girl, who developed disseminated pruritic urticarial and bullous lesions on the trunk accompanied by episodes of vomiting and generalized flushing. Her problems began at the age of 6 months. Her stool was repeatedly positive for occult blood. Histamine and 5-hydroxytryptamine were measured in the urine and serum; urine 5-hydroxytryptamine levels were elevated. In addition, trypsin and chymotrypsin levels were raised in the blister fluid. Metachromatic staining of the mast cells in a skin biopsy specimen confirmed the diagnosis. A combination of oral disodium cromoglycate and ketotifen produced a dramatic improvement of the cutaneous and gastrointestinal features.

Three kinds of neurotransmitters: histamine, acetylcholine and noradrenaline, play important roles in the neural processes of motion sickness, because antihistamines, scopolamine and amphetamine are effective in preventing motion sickness. Histamine H1-receptors are involved in the development of the symptoms and signs of motion sickness, including emesis. On provocative motion stimuli, a neural mismatch signal activates the histaminergic neuron system in the hypothalamus, and the histaminergic descending impulse stimulates H1-receptors in the emetic center of the brainstem. The histaminergic input to the emetic center through H1-receptors is independent of dopamine D2-receptors in the chemoreceptor trigger zone in the area postrema and serotonin 5HT3-receptors in the visceral afferent, which are also involved in the emetic reflex. Antihistamines block emetic H1-receptors to prevent motion sickness. Scopolamine prevents motion sickness by modifying the neural store to reduce the neural mismatch signal and by facilitating the adaptation/habituation processes. The noradrenergic neuron system in the locus coeruleus is suppressed by the neural mismatch signal. Amphetamine antagonizes mismatch-induced suppression of noradrenergic neural transmission, resulting in preventing motion sickness.

Nausea and vomiting are rather stereotyped symptoms. The challenge is that nausea and vomiting have many different causes and, in some patients, management may be rather complex. The clue is to determine the causal factor early. It helps to separate acute vomiting (<48 hours onset) from chronic vomiting. In acute vomiting, the causal factor or factors are most often evident. Symptomatic treatment with parenteral central-type antiemetics is the preferred treatment. Histamine-1 receptor antagonists, phenothiazines, butyrophenones, and corticosteroids are suitable drugs. For specific types of acute vomiting, for example, chemotherapy-related vomiting, the 5-HT3 receptor antagonists are costlier but effective drugs with minimal side effects. Sometimes, oral and parenteral administration of the above-mentioned drugs may be combined. The origin of chronic vomiting is often obscure, requires specialized investigation, and the causative factor may be uncorrectable. Symptomatic treatment requires a value judgement. If delayed gastric emptying is a contributing factor, prokinetic agents (metoclopramide, erythromycin, cisapride in special cases, if authorized) may prove useful. Otherwise, symptomatic treatment with central antiemetics is the only recourse. Some patients with unexplained vomiting present with psychological disturbances that act as magnifying or contributing factors and may be helped by psychotherapeutics.
