Hypersensitivity Reactions and the Respiratory System: Imaging Based Review
Current Problems in Diagnostic Radiology, 2023Hypersensitivity reactions are characterized by inappropriate response of the immune system to an inciting antigen, which results in damage to various body tissues. Respiratory system can be involved as a part of hypersensitivity reaction by a myriad of conditions ranging from infective pathologies like tuberculosis to non-infective processes such as ...

Hapten-specific respiratory hypersensitivity in guinea pigs
American Industrial Hygiene Association Journal, 1978Respiratory hypersensitivity to small chemical determinants (haptens) was produced in guinea pigs by repeatedly exposing the animals to aerosols of hapten-ovalbumin conjugates. In this way, reactivity toward p-azobenzenearsonate and p-tolyl isocyanate was induced. Carrier (ovalbumin)-specific respiratory reactions were not produced.

RESPIRATORY TRACT AND FOOD HYPERSENSITIVITY
Immunology and Allergy Clinics of North America, 1999Respiratory symptom complaints are among the most frequent reasons patients seek medical attention. These symptoms typically include nasal congestion, rhinorrhea, sneezing, itching of the nose and throat, coughing, or wheezing. Numerous causes should be considered in the differential diagnosis (Table 1) of these symptoms.

Propylthiouracil-induced Hypersensitivity Vasculitis Presenting as Respiratory Failure
Chest, 1992Hypersensitivity vasculitis associated with propylthiouracil therapy is a well-documented clinical entity. Although any organ system may be involved, it is most unusual for pulmonary manifestations to be the cardinal presenting features. We report a 72-year-old woman presenting with respiratory failure and hemoptysis following initiation of ...

The role of the gastrointestinal tract in the development of respiratory hypersensitivities
Toxicology Letters, 1996Adverse reactions to foods may sometimes cause symptoms from the respiratory tract, including bronchial obstruction and rhinitis. The true prevalence is not known. In adults, it has been estimated to be about 1% of asthmatic patients or less. This would correspond to a prevalence of about 2-4 in 10,000 of the general population.

Acute respiratory distress caused by erythromycin hypersensitivity.
Archives of internal medicine, 1978Severe respiratory distress developed in a patient after ingestion of two tablets of erythromycin (Erythrocin) stearate. Complete atelectasis of the left lung was found. The patient was treated intravenously with 200 mg of prednisolone sodium tetrahydrophthalate.

The role of the skin in the development of chemical respiratory hypersensitivity
Toxicology Letters, 1996Certain chemicals are known to cause occupational respiratory allergy associated with symptoms of pulmonary distress, including asthma and rhinitis. While there is no doubt that inhalation represents an important route of exposure for the development of sensitization to the inducing allergen, there is evidence that effective sensitization of the ...

Respiratory hypersensitivity and environmental factors: East and West Germany
Toxicology Letters, 1996We assessed the prevalence of asthma and allergic disorders in 9-11 year old children in Leipzig and Halle in East Germany, and Munich, West Germany. Both East German cities were heavily polluted due to private coal burning and industrial emissions, whereas Munich has moderate industry but heavy car traffic. All fourth grade pupils in Munich (n = 7445)

NSAID Hypersensitivity (Respiratory, Cutaneous, and Generalized Anaphylactic Symptoms)
Medical Clinics of North America, 2010Adverse reactions to drugs have been classified as predictable (related to the pharmacologic actions of the drug) and unpredictable (related to the individual's immunologic response or genetic susceptibility). The term "drug hypersensitivity" refers to the symptoms or signs initiated by an exposure to a drug at a dose normally tolerated by ...

Environmental chemicals, respiratory hypersensitization and international chemical safety
Toxicology Letters, 1996Allergic hypersensitization to a variety of chemicals, natural and synthetic, is a worldwide health problem. Respiratory tract hypersensitization is responsible for significant morbidity and, in some cases, mortality. An important step in managing and controlling health risks, such as allergic hypersensitization, is to identify the chemical hazard ...
