Question

. True or false ?

Although rare, an autoimmune response can resemble a Type I reaction.

Answer 1

Answer :

True.

Rarely autoimmune response can mimic type 1 hypersensitivity clinically.

Autoimmune responses are type 3 hypersensitivity.

Immunologically there can be overriding features in type 2 and type 3 hypersensitivity reactions.

Overlapping or mistaken symptoms with type I hypersensitivity and type 3 hypersensitivity are more pronounced in arthus reaction, following repeated bee stings. Chills, fever, rash and urticaria are overlapping symptoms.

But this will be revealed soon as type 1 hypersensitivity is an acute condition and type 3 can be sub acute or chronic.

Also symptoms wont be relieved with treatment for type 1 hypersensitivity.
