In 94% of the patients with dermatitis herpetiformis, a locally applied ointment with an ester of nicotinic acid (Trafuril) induced an abnormal reaction with erythema, edema, papules, and often vesicles. The appearance of the reaction to Trafuril is similar to DH lesions. It differs markedly from the reactions to iodide where, as a rule, only one large blister results. The reaction is most pronounced 12-24 hours after application of Trafuril. The reactivity is strongest in the predilection areas for dermatitis herpetiformis. Strongly increased reactivity to Trafuril in DH is induced by pretreatment with streptokinase, streptokinase-streptodornase, or urokinase. Diminished reactivity to Trafuril is seen after pretreatment with injections of Compound 48/80, tranexamic acid, cromoglycate, or application of fluocinolone-acetonide, as well as after stroking the skin.

Many bacteria that spread in the skin produce enzymes that digest extracellular matrix components. Borrelia burgdorferi spreads from a skin inoculation site to form the characteristic erythema migrans skin lesion. It was determined that B. burgdorferi does not produce collagenase, elastase, hyaluronidase, or other enzymes that digest extracellular matrix components. However, B. burgdorferi bound human plasmin, plasminogen (Pgn), and urokinase-type plasminogen activator (uPA). When spirochetes were sequentially incubated with Pgn and uPA, bioactive plasmin was generated on the surface of B. burgdorferi. B. burgdorferi did not produce an endogenous Pgn activator. Fluorochrome-conjugated uPA and Pgn colocalized to the terminus of the spirochete. In a mouse model, uPA-treated B. burgdorferi were more infectious than control spirochetes. Binding of host uPA and Pgn to form a bioactive extracellular matrix protease on B. burgdorferi represents a mechanism that could facilitate dissemination and localization of spirochetes to sites of vascular injury.
