Abstract

Recent immunological investigations have demonstrated that the patients with psoriasis have various humoral and cellular immune abnormalities, such as increased serum IgG, IgE and secretory IgA, anti-IgC factor in psoriatic lesions, in peripheral blood lymphocytes and in serum, rhumatoid-like factors in IgA and IgG classes of immunoglobulins, antinuclear antibodies (ANA; reacting with the basal cell nuclei of uninvolved skin., anti-stratum corneum antibody and complements in psoriatic scales, immuoglobulin and complement bearing polymorphonuclear leucocytes in the Muro microabscess. These abnormal findings are enough to suggest an autoimmune mechanism in the pathogenesis of psoriasis. Several investigators have also reported the results of T cell enumeration in the peripheral blood in psoriatic patients. However, the results are not in general agreement,. Thee present study was undertaken to clarify any abnormality in the proportion of T cells in the peripheral blood in psoriatic patients. Forty-one patients with active psoriasis registered at the Department of Dermatology, Seoul National University Hospital entered this study from May, 1979 through April, 1980. Twelve healthy medical and paramedical personel the comprised the control group. Active and total T cells were enumerated by the method of E-rosetting technique, and the results were as follows. 1, in normal controls, the active and total T celIs identified as E rosetteforming cells accounted for 61.6+7.4% and 68.1+8.9% of the total lymphocyte population, respectively. 2. In patients with psoriasis, significant decrease of active T cells (54. 2,+11.0%,p<0.005) and total T cells (62.2+11.2%, p<0.05) was observed. More profound reduction of T cells was noted in patients with wide spread psoriasis than those with limited extent.
