Respiratory hazards from papain

Lancet
M L Flindt

Abstract

Late-onset asthma occurred in a non-atopic worker in a factory where papain powder was packed. The patient had had 3 attacks of asthma since first being exposed to atmospheric papain dust. He gave a positive immediate reaction to skin-prick tests with solutions of papain which were appreciably weaker than solutions which caused no reaction in unexposed individuals. These results, together with his history and the fact that symptoms stopped when he was not exposed to papain, suggest that he had extrinsic allergic asthma caused by sensitisation to papain. Shortly after re-exposure to papain a worker in another factory died during an attack of asthma. Measures to prevent the inhalation of papain dust must be taken in factories where papain is handled, not only to avoid the proteolytic effects of the material but also to prevent workers from becoming sensitised.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergies & Environmental Factors

Environmental factors are strongly associated with the prevalence of allergies and are an increasing health concern worldwide. Discover the latest research on Allergies and Environmental Factors here.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
