Pathophysiology The disorder seems to represent a type IV hypersensitivity reaction, in which repeated exposure to antigen in genetically susceptible people leads to acute neutrophilic and mononuclear alveolitis, followed by interstitial lymphocytic infiltration and granulomatous reaction. Damage can be from infection or conditions that injure your airways. Abstract. Byssinosis is a form of reactive airways disease characterized by bronchoconstriction that occurs in cotton, flax, and hemp workers.

It is clinically similar to … This chapter discusses reactions of the large airways to inhalation of toxic substances present in the workplace. BYSSINOSIS PATHOPHYSIOLOGY The pathogenesis of farmer’s lung depends on the intensity, frequency, and duration of exposure and on host response to the causative antigen.  As a result, breathing becomes difficult.
