Linear IgA Bullous Dermatosis

What is linear IgA bullous dermatosis?

Linear IgA bullous dermatosis (LABD), also known as linear IgA disease, is a rare, idiopathic or drug-induced autoimmune blistering disease characterized by the linear deposition of IgA at the dermoepidermal junction.

How do you get linear IgA dermatosis?

Antilaminin 332 antibodies are typically seen in malignancy-associated mucous membrane pemphigoid (MMP). The etiology underlying drug-induced linear IgA dermatosis remains elusive but is speculated to be caused by an immune response towards a drug-derived hapten-protein antigen.

The exact cause of IgA pemphigus is unclear. IgA autoantibodies bind to desmogleins or desmocollins, the cells responsible for adhesion between cells. In SPD-type IgA pemphigus, the autoantigen is described as desmocollin 1, one of the desmosomal cadherins, the glycoproteins that maintain the shape of a cell.
