Of 4087 women (aged 16 to 44 years old; 218 primigravida) subjected to induced abortion during the last 3 years, 762 (18.6%) developed complications. The complications were divided into three groups: group 1 included 64 women who developed complication within the first 7 days after abortion, group 2 included 46 women who developed complications within 7-30 days after abortion, and group 3 included 652 women with late complications. Of 64 women in group 1, 7 had perforation of the uterus, 28 had hematometra, and 29 has incomplete abortion. All 46 women in group 2 has endometritis. Of 652 women in group 3, 4 has placental polyps, 232 has inflammation with associated secondary infertility (hysterosalpingography indicated tubal obstruction in 194 and peritubal adhesions in 38), and 416 had disorders of the menstrual function. In addition to general clinical examination, 50 women with inflammation and tubal infertility underwent immunological examination and allergy testing. Of 50 patients, 35 were found to have skin rush, hives, drug or food hypersensitivity. The patients with allergy manifestations had marked inhibition of cellular immunity seen as decrease in T-lymphocyte count and 2 items increase in null lymphocyte count (B-lymphocyte count did not differ from that in healthy controls). The patients with tubal infertility received combined treatment. Conservative treatment including hydrotherapy, anti-inflammatory agents and electric stimulation was effective 123 of 232 women.

The results obtained in vivo in a group of 24 patients treated with oral cromolyn and compared to a group of 10 patients treated with placebo are reported. All patients were affected by adverse clinical reactions (urticaria and/or angioedema) related to food ingestion. A significant reduction of signs and symptoms were observed after oral cromolyn therapy only in the patients affected by true food allergy (FA), i.e., IgE mediated reactions. No adverse reactions appeared in the treated patients. Because we found an enhancing effect exerted in vitro by cromolyn (SCG) on T-cell responsiveness in previous studies, in the present investigation we analyzed in more detail in vitro effects of SCG on T lymphocytes [i.e., phytohemagglutinin-induced interleukin-2 (IL-2) production] and IL-2 receptor expression on T cells. No significant effect was induced by SCG on IL-2 production, whereas IL-2 receptor expression on surface of T cells appeared significantly increased (P less than 0.001) by adding SCG in cultures. These clinical and immunological results are analyzed and discussed in relation to a possible in vivo effect(s) of cromolyn in allergic diseases.

The authors evaluated the clinical efficacy of an adjunctive treatment with spores of Bacillus subtilis in 20 adult patients with urticaria-angioedema syndrome from food allergy. The patients treated with B. subtilis showed a significant reduction in frequency and severity of clinical features in respect to the patients who received no treatment. Bacillus subtilis spores may increase S-IgA synthesis or protect gastroenteric mucosa.

A multicentre trial conducted on 38 food allergic patients has suggested the following: Food allergy is frequent in children and adults and often induces eczema and urticaria. The diagnosis is based on clinical history, cutaneous tests, RAST and challenges. A treatment with NALCRON associated, in the beginning, with a diet that excludes food allergens usually produces recovery and afterwards re-introduction of allergens, if the dosage of NALCRON is adequate.

For hundreds of years urticaria has been an intriguing problem for researchers. Together with angioedema it constitutes a common condition that affects 20% of the general population. The etiologic diagnosis is obtained in a variable percentage of cases, according to the different studies published. The clinical course and the association with angioedema are also variables in the different works. It was the diversity of results that led us to undertake the present study. We selected 161 histories of children who came to our department of allergology; these children whose ages ranged from 1-12 years were diagnosed of urticaria and/or angio edema. The number of males was slightly higher than females and the most affected age group was that between 7-12 years. The acute and acute intermittent forms predominated especially in atopic children, highly associated with angioedema; chronic urticaria was less frequent. Within the etiologic factors, food allergy played an important role, followed by drug allergy. It was not possible to reach an etiologic diagnosis in 39.13% of cases.

In 20 patients, the ingestion of celery was responsible for mucocutaneous symptoms (generalized urticaria and angioedema) (18/20) and respiratory disorders (7/20). Four cases of systemic anaphylaxis were observed. The main associated allergic disorder was pollinosis (16/20). Food allergy to other vegetable products, mainly other Umbelliferae and apples, coexisted with celery allergy in 12 cases. It was found that celery allergy is mediated by IgE antibodies: it is easily diagnosed by skin tests (fresh extracts of celery may be used) and by adequate RAST (17 positive results). Cosensitization with mugwort pollen (14 cases) and birch pollen (9 cases) was found. Celery allergens responsible for clinical sensitization originate chiefly in the tuber and are at least partly thermally labile. The frequent association with pollen sensitization suggests the existence of common antigenic epitopes in celery extracts and mugwort and birch pollens. The immunologic investigations carried out so far (RAST inhibition and immunoprint) seem to support this hypothesis.

The protocol is proposed in a definite way for recurrent or chronic symptoms. In the first case, the diagnosis is made by PRICK, RAST and provocation tests with suspect foods. On 100 patients, the reliability of PRICK and RAST has been shown. In the second case, a non-allergenic diet and the recurrence of symptoms on the re-introduction of certain foods has permitted isolation of the causative foods and the differentiation of food allergy and intolerance. This has been done with 386 cases of urticaria and angio-oedema, where it has been shown that 1.9% of the reactions had a food-linked origin.

The Restaurant syndromes can be caused by five major factors: food allergens, sulfites, monosodium glutamate (MSG), tartrazine, and scombroidosis (and other seafood poisoning). A history of atopy and ingestion of known food allergens such as peanuts, egg, fish, and walnuts, together with positive results of skin tests or RAST to these foods, will favor a diagnosis of food allergy. Allergic reactions to peanuts have produced fatalities in minutes through an IgE mediated reaction. An extremely rapid onset (minutes) of symptoms consisting of flushing, bronchospasm and hypotension is consistent with a sulfite reaction. Burning, pressure, and tightness or numbness in the face, neck, and upper chest following ingestion of Chinese food favors a diagnosis of adverse reaction to MSG. Also, development of late onset bronchospasm (up to 14 hours) may be related to MSG reactions. Bronchospasm and urticaria in a patient with a history of aspirin intolerance suggests tartrazine sensitivity. If everyone ingesting a fish meal develops flushing, urticaria, pruritus, gastrointestinal complaints, or bronchospasm, this implies scombroidosis, ciguatera, or other seafood poisoning. Finally, severe headache or hypertension can result from ingestion of naturally occurring amines, such as tyramine (cheese, red wine) and phenylethylamine (chocolate). A double-blind oral challenge test may be the only way of confirming the diagnosis for most of the etiological factors of the Restaurant syndromes. The treatment of choice for acute reaction is epinephrine followed by antihistamine. Proper labeling and avoidance of these ingredients in sensitive individuals are the best preventive measures.

Possible associations between allergy to grass pollen and positive skin tests to food allergens were studied in 102 children monosensitized (as to inhalant allergens) to grass pollen, and in 117 children monosensitized (as to inhalant allergens) to Dermatophagoides. Thirty-two foods were tested by an epicutaneous method. Positive skin tests to food allergens were more frequent in children with allergy to grass pollen (59.8%) than in children with allergy to Dermatophagoides (9.4%). A considerably high frequency of positive reactions to tomato (39.2%), peanut (22,5%), green pea (13.7%), and wheat (11.7%) was observed in children with allergy to grass pollen. Positive skin tests to peanut closely correlated with positive RAST results and nasal provocation tests, whereas in children with skin test positivity to tomato a close correlation with nasal provocation tests but a 45% correlation with a positive RAST result were observed. RAST inhibition experiments were carried out, and the results may suggest the presence of cross-reacting IgE to grass pollen, tomato, and peanut antigens. Clinical implications of these findings are discussed in the light of histories of food hypersensitivity, urticaria-angioedema, and atopic dermatitis in children with allergy to grass pollen.

The First National Health and Nutrition Examination Survey (NHANESI), conducted in 1971-1975, included a cohort of 6913 adults for whom history of smoking, allergies, and other factors was obtained. These persons were traced (with 93% success) approximately 10 years later by the NHANESI Epidemiologic Followup Survey, and incidence of malignancy in the interim period was determined. Primary allergy variables were physician-diagnosed asthma, hay fever, hives, food allergy, or other allergies. Excluded were persons with a prior history of cancer and cases of nonmelanoma skin cancer. After adjustment by logistic regression for age, sex, race, and smoking history, allergic history was found to increase the risk of subsequent malignancy (risk odds ratio = 1.40, 95% confidence interval = 1.10-1.77). The specific allergy type with the strongest cancer risk was hives. The cancer group with the strongest allergy association was lymphatic-hematopoietic (leukemia, lymphoma, myeloma). The risk odds ratio of developing leukemia, lymphoma, or myeloma for persons with hives history was 7.89 (95% CI = 3.13-19.89). These findings suggest that a history of allergy does not protect against subsequent cancer, and may be a risk factor. The possibility is raised that a history of hives may be a particular risk factor for lymphatic-hematopoietic malignancies.
