Serum immunoglobulin levels and tissue antibodies in psoriasis.

Abstract

Serum samples from psoriatic patients were subjected to quantitation of serum IgA, IgG and IgM levels and screening of tissue autoantibodies including ANA, GPA, MTA and SMA. Serum IgA was found to be significantly elevated and incidences of ANA and GPA were also increased. Their significance and possible mechanism were discussed.
