Meaning and Definition
A type of local, inflammatory immune response caused by the formation of antigen-antibody complexes in tissues.
A severe, localized hypersensitivity reaction (Type III) characterized by pain, swelling, redness, and tissue damage, typically occurring several hours after injection of an antigen in an individual with high levels of circulating antibodies against it. It is an eponym named after the French bacteriologist Nicolas Maurice Arthus.

FAQ
Frequently Asked Questions
No, it is a relatively uncommon adverse event, mostly seen in specific medical or research contexts where antigens are injected into individuals with high pre-existing antibody levels.
While typically localized and self-limiting, severe cases involving extensive tissue necrosis or occurring in critical locations can be serious, but it is not typically systemic and immediately life-threatening like anaphylaxis.
Anaphylaxis is an immediate (Type I) hypersensitivity mediated by IgE, causing systemic effects. The Arthus reaction is a delayed (Type III) hypersensitivity mediated by IgG/IgM and immune complexes, causing localized inflammation.
They are related but distinct. Both are Type III hypersensitivities. The Arthus reaction is a severe, localized response. Serum sickness is a systemic reaction (e.g., fever, rash, joint pain) caused by circulating immune complexes, often following administration of foreign sera or certain drugs.
A type of local, inflammatory immune response caused by the formation of antigen-antibody complexes in tissues.

Learning
Memory Aids
Mnemonic
Think of 'Arthur's' knights causing a local battle (inflammation) in the tissue, several hours after a challenge (antigen injection).
Conceptual Metaphor
THE IMMUNE SYSTEM IS AN ARMY; the Arthus reaction is a MISFIRED or EXCESSIVE COUNTER-ATTACK causing collateral damage to the body's own territory (tissues).
