Epidermolysis bullosa acquisita (EBA) is a rare autoimmune subepidermal blistering disease caused by IgG (and sometimes IgA) autoantibodies against type VII collagen (Col7), the major component of anchoring fibrils at the dermal-epidermal junction, triggering complement C3/C5a-mediated neutrophil and eosinophil degranulation with MMP-9/elastase dermal-epidermal cleavage and skin fragility. EBA involves NF-kB amplification, IL-17/IL-8 neutrophilic cascade, and TGF-beta fibrotic scarring in the mechanobullous form. Sea moss fucoidan modulates complement C3/C5a and NF-kB; selenium supports keratinocyte and dermal fibroblast GPx protection; zinc supports type VII collagen stabilization and epithelial barrier metallothionein; omega-3 modulates LTB4/IL-8 neutrophilic eicosanoids. Colchicine, dapsone, cyclosporine, and rituximab are standard; sea moss provides anti-inflammatory nutritional support.
