Understanding M36.4: Arthropathy in Hypersensitivity Reactions

Definition and Causes

Arthropathy in hypersensitivity reactions is characterized by joint inflammation and pain resulting from an immune response to an allergen or irritant. This can occur in conditions such as drug-induced hypersensitivity, serum sickness, or reactions to infections. The immune system's overreaction leads to inflammation in the joints, causing symptoms similar to other forms of arthritis.

Symptoms

Common symptoms associated with M36.4 include:
- Joint pain and swelling
- Stiffness, particularly in the morning or after periods of inactivity
- Possible fever or malaise, depending on the underlying cause

Standard Treatment Approaches
