What Is Late Phase Allergic Reaction. Signs and symptoms of delayed or late-phase allergic reactions are generally the same as those for immediate allergic reactions. Anaphylaxis is usually defined as a multi-system allergic reaction but includes isolated shock or airway obstruction. It is usually preceded by a clinically evident early-phase reaction and fully resolves in 12 days. In the lung the immediate response begins within minutes or even seconds after exposure to an allergen.
Allergy symptoms may include itchiness. In the case of allergic asthma a delayed allergic reaction can cause other problems such as loss of sleep due to nighttime. Signs and symptoms of delayed or late-phase allergic reactions are generally the same as those for immediate allergic reactions. In the lung the immediate response begins within minutes or even seconds after exposure to an allergen. When certain situations are present they may also play a role in severe asthma and allergic asthma symptoms. A reaction that typically develops after 26 h and peaks 69 h after allergen exposure.

Late Phase The cells remain viable after degranulation and proceed to synthesize other substances which will be released at a later time causing the late phase of a type I hypersensitivity reaction. A reaction that typically develops after 26 h and peaks 69 h after allergen exposure. IL-13 is detected in the nasal membranes of both human beings and mice with allergic rhinitis but its role in disease pathogenesis is unclear. Eosinophils play a significant role in the late phase asthma attack.
