We have been able to detect circulating endotoxin in six of 11 patients with psoriasis.

Our interest in the possibility of endotoxemia in psoriasis followed recent demonstrations of alterations in levels of alternative complement pathway components¹ and of circulating IgA immune complexes in psoriasis.² Endotoxin and immune IgA complexes each activate the alternative complement pathway.^3,4
