Arthus reaction

The Arthus reaction, a localized inflammatory response, is named after him.

Rheumatoid arthritis or Arthus reaction belong to this category.

Arthus reactions have been infrequently reported after vaccination against diphtheria and tetanus.

If the animal/patient was previously sensitized (has circulating antibody), an Arthus reaction occurs.

The Arthus reaction was discovered by Nicolas Maurice Arthus in 1903.

Skin response to a hypersensitivity of this type is referred to as an Arthus reaction, and is characterized by local erythema and some induration.

In immunology, the Arthus reaction is a type of local type III hypersensitivity reaction.

The Arthus reaction involves the in situ formation of antigen/antibody complexes after the intradermal injection of an antigen.

If a patient receives a booster dose this is a good thing but already has a high level of antibody, then a reaction called an Arthus reaction could develop, a localized form of Type III hypersensitivity, induced by fixation of complement by preformed circulating antibodies.
