Immunological studies in psoriasis.
The mean values of serum immunoglobulins A, G, M and D levels in 42 psoriasis patients showed no significant difference from those of control subjects. Analysis of the same sera for the presence of antiglobulin antibodies also yielded negative results. Antinuclear factor could be demonstrated in only 4.8% of the cases. The possibility that serum antiglobulins get drained into the lesions making their detection in the serum difficult, is supported by our preliminary findings of focal deposition in the stratum corneum of immune complexes of IgG, IgM and complement in tissue sections of psoriatic lesions from these patients.
