Linear IgA dermatosis · Linear IgA bullous dermatosis · Lineare IgA-Dermatose · Lineare IgA-Krankheit · Canine linear IgA disease
This is a rare autoimmune disease affecting the skin, where the dog's immune system mistakenly produces IgA antibodies that attack proteins in the basement membrane zone, which is the boundary layer between the outer and inner skin. This attack weakens the skin layers, leading to blister formation. Diagnosis is typically confirmed using a skin biopsy test called direct immunofluorescence (DIF) to detect these specific antibody deposits.
Owners will typically notice itchy or painful blisters, redness, crusts, and open sores on their dog's face, ears, and paws. These symptoms usually first appear during young to middle adulthood.
While the condition is incurable and requires lifelong immunosuppressive therapy and regular veterinary monitoring, it can be managed. Lifetime treatment and care costs typically range from 2,000 to 7,000 EUR.
