There are four types of protein contact dermatitis: animal, proteolytic enzymes, plant, and flour. The risk factors for this include protein allergens, atopy, and chronic dermatitis. There have been several theories proposed for protein contact dermatitis. Many Scientists are of the view that this occurs due to type 1 hypersensitivity.
Some are of the view that this results from type 1 and type 4 hypersensitivity reactions. Many also believe that this results due to a mediated immunoglobulin E hypersensitivity reaction. All the above three theories have been backed by enough proofs to support the model. No particular sexual or racial predilection is known for this infection. People can get affected with protein contact dermatitis at any age.
Proteins responsible for protein contact dermatitis:
There are four segments of proteins that can result in protein contact dermatitis.
Symptoms and diagnosis:
Protein contact dermatitis shows symptoms such as lichenification, erythematous papules, and dermatitis affecting the forearms. At times the fingertips get affected too. A doctor might prescribe a patch test followed by prick and scratch test. Other tests involve a fungal test, open application testing, radioallergosorbent testing, image studies, and biopsy.
The key to avoiding protein contact dermatitis is to stay away from the protein causing the disease. For short-term reliefs, a doctor can prescribe corticosteroids and antihistamines. A patient might have to get admitted to a hospital if the severity level of the disease is so much that the patient is suffering from gastrointestinal distress and angioedema. Medication involves oral dosage of antihistamines and clobetasol propionate.
