In this review I have described the pathophysiology of allergic disorders of the gastrointestinal tract. Situations where the intestine cannot be a complete barrier to foreign allergens and antigens were discussed and etiological factors of gastrointestinal allergy were detailed. Clinical features of gastrointestinal allergy include diarrhea, vomiting, abdominal pain and colic, intestinal hemorrhage and malabsorption as well as symptoms and signs outside the gastrointestinal tract such as chronic rhinitis and asthma in the respiratory system, urticaria, angioedema and eczema as dermatological signs, headache, insomnia, hyperkinesis as central nervous system manifestations, failure to thrive and anaphylaxis as constitutional reactions. Milk allergy was discussed as an example of food allergy. Immunology of the gastrointestinal tract was presented, with examples of four types of hypersensitivity reactions, and gastrointestinal disturbances of immunodeficiency disorders and syndromes were named. Lastly, the autoimmune mechanism and the gut were described, with particular discussion of ulcerative colitis as an example of an autoimmune disease.

ImuVert, a new biological response modifier, was evaluated for toxicity and potential efficacy in patients with advanced cancer. This agent consists of sized, labile, natural membrane vesicles associated with ribosomes derived from Serratia marcescens. ImuVert induces enhanced in vitro macrophage and natural-killer-cell-mediated cytotoxicity, and has demonstrated antitumor activity in palpable animal tumor systems. A group of 39 patients with a variety of tumors, 25 men, 14 women, with a mean performance status (Karnofsky) of 80% and median age of 57 years were entered into this trial. ImuVert was administered subcutaneously weekly for a minimum of 3 weeks. A total of 183 treatments were evaluated. Flu-like systemic toxicities, including fever, chills, nausea, vomiting, diarrhea and hypotension were observed. Erythema, induration and tenderness developed at the injection sites. Myelosuppression, thrombocytopenia, anaphylaxis, rental and hepatic toxicities did not occur. All symptoms resolved within 24 h. Two patients with nodular lymphoma achieved a partial response and two minor responses were seen in patients with glioblastoma and melanoma. On the basis of ImuVert's biological activity, and tolerable toxicity it warrants further clinical investigation.

Allergic reactions have been described as an occupational hazard among nurses and pharmaceutical workers who handle psyllium-containing laxatives. This study reports the case of a 38-year-old female nurse who ingested a bowl of psyllium-containing Heartwise Cereal (Kelloggs, Battle Creek, MI) and 25 minutes later developed severe systemic anaphylaxis manifested by hypotension, a feeling of constriction in the throat, hoarseness, dyspnea, wheezing, generalized pruritus, urticaria, and vomiting. She was treated with epinephrine, normal saline, diphenhydramine, and methylprednisolone, and recovered completely. Subsequent IgE immunoblot assay was strongly reactive to psyllium. Ingestion of psyllium-containing breakfast foods by sensitized individuals can be associated with life-threatening systemic anaphylaxis.

Intravenous fluorescein angiography is a commonly performed and extraordinarily valuable diagnostic procedure. The frequency of adverse reactions after angiography has varied considerably in previous reports. In a prospective study of 2789 angiographic procedures in 2025 patients, the authors found that the percentage of adverse reactions depended strongly on the patient's angiographic history. Overall, adverse reactions followed 4.8% of the angiographic procedures. These reactions included nausea (2.9%), vomiting (1.2%), flushing/itching/hives (0.5%), and other reactions (dyspnea, syncope, excessive sneezing) (0.2%). No cases of anaphylaxis, myocardial infarction, pulmonary edema, or seizures occurred. The percentage of reactions was 1.8% for patients who had had previous angiography without ever having had an adverse reaction. In contrast, the percentage of reactions was 48.6% for patients who had had an adverse reaction to angiography previously.

Clinical and immunologic responses of sheep to vaccination and subsequent bluetongue virus (BTV) challenge exposure were studied and compared with those of non-vaccinated sheep. Sheep were vaccinated with inactivated BTV administered with aluminum hydroxide and cimetidine or levamisole. After sheep were vaccinated, precipitating group-specific antibodies to BTV were detected, but serotype-specific neutralizing antibodies were not detected. Cellular immune responses (lymphocyte blastogenesis) to BTV were not detected. After virulent BTV challenge exposure, vaccinated and nonvaccinated sheep developed acute clinical disease of similar severity. Clinical signs included hyperemia and petechiae of oral mucosa and coronary bands of the feet, excess salivation, nasal discharge with crusting, ulceration of the muzzle, and edema of lips and intermandibular space. Marked increases in serum creatine kinase activity were associated with stiff gait, reluctance to move, and vomiting. Fever and leukopenia were detected in most of the challenge-exposed sheep. Viremia and neutralizing antibodies were detected in vaccinated and nonvaccinated sheep after challenge exposure. Bluetongue virus-specific reaginic antibodies were not detected in sera from any of the sheep when the passive cutaneous anaphylaxis test was used.

The diagnosis of cow's milk proteins allergy can only be established if the symptoms disappear with an elimination diet and if a later controlled challenge leads either to a recurrence of symptoms or to some other clearly identified changes. At the moment there is not a specific immunological test surely effective in all cases. Anyway the three Gooldmann's tests are not necessary. In fact a single challenge with a cow's milk meal will be sufficient when clinical observation is accompanied by monitoring some simple laboratory tests (serum and nasal eosinophils, steathorrea, coproleucocytes, hemoccult, xylosemia and leucocytes PMN). The challenge must be tested in a double-blind trial only in patients with non specific symptoms (such as tension fatigue syndrome, hyperactivity, ecc...). The double-blind challenge is not necessary generally for the diagnosis of cow's milk proteins allergy in childhood, because at this time of life not only the symptoms are very clear (diarrhea, vomiting, skin symptoms) but also there is a prevalence of non reaginic reactions: this kind of reactions are usually delayed and they generally occur after a relatively high dose of food allergens. In the group of patients with specific anti-cow's milk IgE (RAST and prick tests) and severe reactions (anaphylaxis), the challenge is not necessary to confirm the diagnosis, but is usefully to verify the acquired tolerance, generally after the first year of life.

Gastrointestinal food allergies may be defined as clinical syndromes which are characterised by the onset of gastrointestinal symptoms following food ingestion where the underlying mechanism is an immunologically mediated reaction within the gastrointestinal tract. These gastrointestinal symptoms, principally vomiting and diarrhoea, sometimes abdominal colic, may be accompanied by other symptoms outside the alimentary tract. The clinical spectrum of these disorders ranges from acute anaphylaxis (rarely leading to death in infancy) to relatively minor symptoms which are difficult to distinguish from other disorders such as toddler's diarrhoea or psychologic disorders. The same food, e.g. cow's milk, may produce a wide range of clinical manifestations. In the one individual, clinical features may change with age. The incidence of gastrointestinal food allergic disease is greatest in the first year of life and decreases with age. There are, broadly speaking, two categories of clinical syndromes which are related to speed of onset of symptoms: immediate and delayed. Those syndromes which manifest immediately after food ingestion are usually easy to diagnose and specific IgE tests and skin prick tests are frequently positive. Those which have a delayed onset of up to several days are difficult to diagnose, and currently available investigations may be unsatisfactory for routine use. In current clinical practice, gastrointestinal syndromes which can be manifestations of food allergy, may be grouped as follows: 1) immediate syndromes, including anaphylaxis and b) acute vomiting +/- diarrhoea in association with cutaneous and respiratory manifestations; and 2) delayed syndromes, including a) food-sensitive small intestinal enteropathies, b) food-sensitive colitis, c) multiple food allergy +/- enteropathy, and d) infantile colic.(ABSTRACT TRUNCATED AT 250 WORDS)

Snake bite was diagnosed in 125 dogs and 115 cats over 10 years. Young sporting dogs and young cats were mainly affected. More dogs (48%) were seen in contact with tiger snakes than cats (7%). One hundred and four (84%) dogs and 89 (76%) cats were bitten in the warmer months of the year (October to March). As the incidence rose in September/October, dogs were bitten on days when the temperature was near 20 degrees C or over. The commonest presenting signs were dilated pupils and absences of pupillary light reflex. Dyspnoea, hypothermia, hindleg ataxia and glycosuria were common features in cats. Vomiting, tachypnoea, hyperthermia and complete flaccid paralysis were often seen in dogs. The overall recovery rate after administering antivenene was 90% for cats and 83% for dogs. Death from anaphylaxis as a result of giving antivenene occurred in 3 cats and one dog. Dogs treated soon after being bitten recovered more rapidly. There was no correlation between the bite-to-treatment period and the treatment-to-recovery period for cats.

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.

Echinomycin is a novel bifunctional intercalating agent derived from Streptomyces echinatus. A phase II clinical trial of echinomycin in patients with advanced, measurable colorectal cancer was initiated to determine the efficacy and toxicities of this agent. Echinomycin, 1.5 mg/m2, was given initially as a 30- to 60-min infusion every 4 weeks. After 4 episodes of anaphylaxis had occurred among the first 14 patients, the schedule was changed to a 24-h infusion, and an additional 16 patients were treated on this schedule. Treatment was given every 3 weeks. A total of 30 patients were eligible and evaluable; there were 3 (10%; 90% confidence interval, 3%-23%) clinical responses lasting 3, 3+, and 12 months, respectively. The most serious toxicity encountered was anaphylaxis, which occurred in 5 patients, although with no serious sequelae. A premedication regimen with dexamethasone, diphenhydramine, and cimetidine and a change of the duration of the infusion to 24 h reduced the incidence of this complication. Grade 2-3 vomiting occurred among earlier patients treated; however, with the 24-h schedule this toxicity was substantially reduced. The sole important case of hematologic toxicity was a single patient with grade 3 thrombocytopenia. Echinomycin employed in this dose and schedule had modest activity against colorectal cancer, comparable with that observed with 5-fluorouracil. Further studies in patients with gastrointestinal malignancies using a 24-h infusion with a dexamethasone premedication regimen similar to that employed prior to administration of taxol may be warranted.
