Quantification of HTLA-positive lymphocytes during oral photochemotherapy of psoriasis.
T-lymphocyte count in the peripheral blood, based on the identification of anti-human lymphocyte antigen (HTLA) by an immunocytochemical method, was determined in 25 PUVA-treated psoriatics and in 25 controls matched by sex and age. The results demonstrate that the HTLA-positive lymphocyte counts of these two groups do not differ significantly. It is concluded that oral photochemotherapy does not induce quantitative modifications in the population of T-lymphocytes of the blood.
