Similar: Asthma is, in most cases, an allergic reaction caused by ige or the allergy antibody. Hypersensitivity pnemonitis is a different immune reaction caused by igg, usually. Both can make one short of breath but the reason for this symptom is different pathology.

What is effected: Asthma is a disease of chronic mid to small airway inflammation, sometimes caused by allergens but not always. Hypersensitivity pneumonitis is inflammation of the lung tissue itself as the result of exposure to allergens (eg birds) , it usually resolves when the allergen is removed, although long term exposure can lead to scarring.

Very different: Hp is a hypersensitivity reaction usually to some organic material usually mold, but also food particles, bird droppings, pets, grains, etc. Asthma presents with mostly reversible airway obstruction due to exercise, allergens, infections. Both can present with sob, cough, wheezing, but hp can also have fever. Hp usually resolves or kept from turning into fibrosis, once removed from trigger.
