The authors followed up the health of 322 elementary-school pupils at Sabac who were exposed to increased air pollution with chemical agents (ammonia, fluor hydrogen, chloracetic acid, sulfur dioxide, soot). The mean annual concentration of these gases were above or insignificantly under maximally permitted values. The results of the examination were as follows: recurrent cough in 12.4 per cent of cases and clinical signs of chronic or obstructive bronchitis in 8.4 per cent of children. Values of vital capacity were under normal in 27.6 per cent of cases and almost in the half of children vital capacity was at the lower normal limit. FEV1/FVC was under normal in 15 per cent of cases and at the lower normal limit in about 18.6 per cent of children. In spite of a great number of children with positive cutaneous tests to inhalation allergens with Prick's method IgE was within normal limits in these children. Thus, a significant noxious effect of allergic components on respiratory organs should be excluded. This was also confirmed by spirometric measurements of the two subsequent maximal expiriums when differences of +/- 3% were registered. However, in children with allergic bronchitis the value dispersion was by 2-3 times greater. Consequently, the authors concluded that damaged respiratory organs in children at Sabac appeared in a greater number of cases than in other places and that these damages were due to increased concentrations of different chemical air pollution agents.

Rhinoconjunctivitis induced by pollen exposure and bronchial asthma are generally easily recognizable clinically. In asthma a number of differential diagnoses such as ciliary dyskinesia, cystic fibrosis and gastro-oesophageal reflux must be considered. The predominant symptoms are coughing and wheezing. Investigations into the complex nature of mediator release and IgE synthesis have established a predominantly inflammatory pattern of reactions largely responsible for induction and maintenance of bronchial hyperresponsiveness due to both acute and chronic processes. Future therapeutic consequences may be derived from anti-inflammatory strategies. This has already lead to reassessment and upgrading of use of corticosteroids in paediatric asthma.

The diagnosis of drug-induced pneumonitis is generally difficult, and it is made clinically by Tamura's criteria. We experienced 12 cases (7 definite and 5 possible cases) of antimicrobial drug-induced pneumonitis (one of case was the first case caused by carbapenem). Symptoms such as fever (11/12), cough (10/12) and dyspnea (10/12) and laboratory data such as eosinophilia (7/12), elevation of IgE (4/6) and hypoxia (11/12) were commonly seen in these patients, although they were not specific. Lymphocyte stimulation test (5/11) and provocation test (4/8) were quite suggestive of drug allergy. Bronchoscopy has been used for confirmation of pneumonitis. Transbronchial lung biopsy revealed alveolitis (4/9) or alveolar fibrosis (3/9), and bronchoalveolar lavage showed lymphocytosis (6/6) and depression of OKT4/T8 ratio (3/5). The combination of bronchoscopic and immunological examinations were more confirmative for diagnosis.

A 37-year-old female with refractory asthma taking betamethasone orally (1 mg/d), showed a fever of 38.5 degrees C, productive cough and dyspnea. The chest X-ray demonstrated diffuse infiltration in the left lower lung field. The WBC count was 16,000/mm3 with 6% eosinophils. She was treated with intravenous drip infusion of antibiotics (Cefotiam 2 mg/d and Sisomicin 150 mg/d) for 2 weeks, and her symptoms and the chest X-ray findings improved. However, at the end of the therapy eosinophilia was noticed. Sixteen days after the completion of antibiotic therapy, she again experienced fever, cough and dyspnea. The chest X-ray again demonstrated diffuse infiltrations in the left lower lung field. The total IgE level, histamine and circulating immune complex titers were elevated. The WBC count was 14,700/mm3 with 34% eosinophils. Although a sputum culture yielded no organisms, many eosinophils were observed in the sputum. There were no clinical or laboratory findings compatible with allergic broncho-pulmonary aspergillosis. After the administration of oral prednisolone (40 mg/d), the patient showed rapid improvement with resolution of all symptoms and normalization of the IgE, histamine and circulating immune complex levels. The chest X-ray revealed marked regression of the pulmonary infiltrations. A microscopic examination of a transbronchial biopsy specimen demonstrated moderate eosinophilic infiltrations. It was compatible with the diagnosis of pulmonary infiltration with eosinophilia. Treatment was performed with prednisolone. The result of a lymphocyte stimulation test was positive for Cefotiam. An in vitro test was performed to evaluate the diagnosis of drug allergy in this case.(ABSTRACT TRUNCATED AT 250 WORDS)

The background and aetiology of chronic cough were investigated by comparing 60 children under 6 years with simple cough, 60 children with asthma, and 60 controls. Both cough and asthma were more common in boys and associated with a history of eczema, chest deformity, and skin reactivity to inhaled allergens, but these findings were more prevalent in asthma than cough. House dust mite sensitivity was found in 34 (57%) children with cough, 45 (75%) with asthma, and six (10%) controls. Tests of immunological function showed some high concentrations of IgM in groups with both cough and asthma, but high IgE concentrations, eosinophilia, and lymphocytosis were significant only in asthma. IgG1 and IgG2 concentrations were raised in some children with cough or asthma, but the only low subclass concentrations were of IgG3 observed in the group with cough. Children with simple cough represented a heterogeneous population but many showed evidence of atopy. Major defects of immunity were not observed.

We assessed the relationships of clinical symptoms and serum antibody levels during follow-up of 47 patients, aged 3 to 66 months, who were shown by formal milk challenge to have cow milk allergy. Three groups of patients were identified. Group 1 patients (n = 15) were sensitized to IgE and responded rapidly to small volumes of milk with urticaria, an exacerbation of eczema, wheeze, or vomiting. In the second group (n = 24), symptoms of milk enteropathy (vomiting and diarrhea) developed between 1 and 20 hours after milk ingestion. In the group 3 patients (n = 8), coughing, diarrhea, eczematoid rashes, or a combination of these developed more than 20 hours after normal volumes of milk were given. Serum levels of IgG, IgA, IgM, and IgE and of milk-specific anti-cow milk antibodies of these isotypes were measured initially and then at a median follow-up time of 16 months (range 6 to 39 months). In this investigation, changes in these immunologic measures during the study period were related to whether or not clinical tolerance to cow milk was achieved. At follow-up, six patients from group 1, ten from group 2, and two from group 3 were milk tolerant. No consistent change in any of the immunologic measurements was associated with remission of the disease. These findings raise the question of whether acquisition of clinical tolerance to cow milk in cow milk allergy can be attributed solely to immunologic events.

A case of allergic oculorhinitis induced by toluene diisocyanate (TDI) exposure in a subject who two years later developed bronchial asthma due to TDI is described. A 55-year-old nonatopic spray painter developed symptoms of oculorhinitis two or three hours after direct occupational exposure to polyurethane varnish; at the first examination neither specific nor nonspecific bronchial hyperresponsiveness was present. Two years later the patient, who had remained in his job, developed episodic dyspnea, wheezing, and cough immediately after TDI exposure, with persistence of oculorhinitis; at this time a slight immediate-type response to a specific bronchial provocative test with polyurethane varnish and TDI was observed. Nonspecific bronchial hyperresponsiveness was mild. Specific IgE to TDI-HSA conjugate was present at both the first and second examinations. We conclude that, in some cases, TDI may cause "allergic" oculorhinitis and bronchial asthma, probably with an immunological IgE-mediated mechanism.

A 43-year-old woman developed asthma 6 years after beginning work in a food-processing plant in which soybean flour was used as a protein extender. Symptoms of sneezing, coughing, and wheezing would begin within minutes of exposure to soybean flour and resolve 2 hours after exposure ceased. Skin tests were positive to a soy extract prepared from the flour. Airway hyperreactivity was confirmed by a positive bronchial challenge to methacholine. Bronchial challenge with soybean flour produced an immediate increase in specific airway resistance from 5.0 to 22.7 L. cm of H2O/L/sec. There was no response to challenge with lactose. The patient's allergic response to soy-flour extract was further characterized by several immunologic methods. IgE binding to soy-flour protein by direct RAST was 5.98 times that of a normal control serum. The soy-flour extract was separated by dodecyl sulfate-polyacrylamide gel electrophoresis. Twenty-four protein bands were detected in the crude soy-flour extract. After immunoblotting and subsequent autoradiography, nine proteins with molecular weights ranging from 54,500 to 14,875 were found. Cross-reactivity studies with other legumes demonstrated apparent immunologic identity between a component in green pea extract and a soybean protein with a molecular weight of 17,000. The clinical significance of this cross-reactivity is not known. We conclude that in this case of occupational asthma to soybean flour, multiple allergens were involved. Immunoblotting may be useful in identifying the allergens involved in occupational asthma.

We report our second case of chronic eosinophilic pneumonia (CEP) (Carrington's pneumonia) with elevated serum IgE values and present a review of the literature on this subject. Our present patient, a 55-year-old woman, had classic symptoms of dry cough, weight loss, malaise, dyspnea, night sweats, and fevers. Significant peripheral blood eosinophilia and a right upper lobe infiltrate were present. Glucocorticoid therapy caused prompt resolution of symptoms, as well as disappearance of blood eosinophilia, elevated serum IgE levels, and pulmonary shadowing. The diagnosis of CEP should not be neglected in the classification of the eosinophilic pneumonias with increased serum IgE levels. The increased serum IgE levels, when present in CEP, seem nonspecific and thus may not be useful as a diagnostic adjunct. However, measurement of IgE may be helpful in CEP, as it has been in allergic bronchopulmonary aspergillosis, to guide the dosage and duration of corticosteroid therapy.

Immunological and respiratory findings were studied in a group of 45 female spice-factory workers (mean age: 39 years; mean exposure: 17 years). In addition a group of 45 female control workers matched by sex, age, and smoking habit were also studied. Intradermal skin testing with mixed spice dust allergen demonstrated positive skin reactions in 73.3% of exposed and in 33.3% of control workers (P less than 0.001). Increased IgE serum levels were found in 36.8% of exposed and in 9.7% of the control workers (P less than 0.01). The prevalence of chronic respiratory symptoms was significantly higher in the exposed workers than in the control workers (P less than 0.01). There was, however, no consistent correlation between skin reactivity and chronic respiratory symptoms. There was a high prevalence of acute symptoms during the work shift. These complaints were more frequent in workers with positive skin tests for the symptoms of cough, chest tightness, and irritated and dry throat. Ventilatory capacity was measured by recording maximum expiratory flow-volume (MEFV) curves. There were statistically significant mean reductions during the work shift for all measured lung function parameters in workers with positive skin reactions. In those workers with negative skin reactions only FEF50 and FEF25 reached statistical significance. Aqueous extracts of different spices (chilli pepper, paprika, caraway, coriander leaves, coriander seeds, cinnamon, ginger, onion, curry, and parsley) caused a dose-related contractile response of isolated guinea pig tracheal smooth muscle. These data suggest that immunologic reactions to spices are frequent in spice workers and may be related to acute symptoms and lung function changes, but not to chronic changes. The data further suggest that, in addition to any immunologic response these spices may produce in vivo, they probably also provoke direct irritant reactions in the airways as suggested by in vitro data.
