Hereditary Angioedema
Full Form of HAE
What is HAE?
Hereditary Angioedema (HAE) is a rare genetic disorder characterized by recurrent episodes of severe swelling beneath the skin and mucous membranes, affecting areas such as the face, limbs, gastrointestinal tract, and airways. It is caused by a deficiency or malfunction of the C1 inhibitor protein, leading to uncontrolled activation of the complement and contact systems. In India, HAE is underdiagnosed due to lack of awareness and limited access to diagnostic facilities, but recent efforts by patient advocacy groups and medical societies are improving recognition and management. The condition typically manifests in childhood or adolescence and persists throughout life. Episodes can be triggered by stress, injury, infections, or certain medications like ACE inhibitors. Treatment includes on-demand therapies such as icatibant and ecallantide, as well as prophylactic options like attenuated androgens or C1 inhibitor replacement. HAE is distinct from allergic angioedema as it does not respond to antihistamines or corticosteroids. For medical students and practitioners in India, understanding HAE is crucial for board examinations such as NEET PG and USMLE, where it appears as a high-yield topic in immunology and dermatology. Early diagnosis and appropriate management can significantly reduce morbidity and improve quality of life for affected individuals.
