Question

What is anaphylactic shock?

पर्याय

• A severe acute emergency where a person develops shock after injection of a foreign protein due to sensitization from a previous dose

• An immune deficiency disorder characterized by low antibody production

• A mild allergic reaction with localized symptoms

• A chronic progressive condition that develops slowly over years

Answer 1

Anaphylactic shock is a severe acute emergency that occurs when a previously sensitized individual is exposed to a foreign protein again, even in small amounts. The prior exposure has created IgE antibodies bound to mast cells throughout the body. Upon re-exposure, massive simultaneous discharge of histamine and other mediators from mast cells occurs, causing systemic reactions including extreme hypotension, shock, and potentially death if not treated immediately with adrenaline.
