CAUSES OF LINEAR IMMUNOGLOBULIN A (IGA) DERMATOSIS (LAD)
Linear Immunoglobulin A (IgA) Dermatosis (LAD), which was formerly known as chronic bullous disease of childhood, is an autoimmune disease. It can be triggered by:
1. Drugs like vancomycin, amiodarone and amoxicillin-clavulanate.
2. Chemicals like tea tree essential oil and sodium hypochlorite have also been associated with it.
3. Diseases like typhoid, brucella and tuberculosis have also been associated with LAD.
Symptoms of Linear Immunoglobulin A (IgA) Dermatosis include:
1. Tense vesicles and bullae (balloon like fluid filled swellings) which are usually roundish and clear
2. Some patients may develop itching before the blisters develop.
3. Around half of the patients with LAD develop ulcers in their mouth.
