Adenosine deaminase activity in sera of patients with psoriasis, mycosis fungoides and adult T cell leukemia.
Adenosine deaminase activities in sera were measured in 18 psoriatic patients, 8 mycosis fungoides patients, and 9 patients with adult T cell leukemia. Adenosine deaminase activity in the sera of the psoriatic patients showed no significant increase. An elevated adenosine deaminase activity was observed in 7 of the 8 patients with mycosis fungoides and 8 of the 9 patients with adult T cell leukemia. After chemotherapy, adenosine deaminase activity in serum of acute adult T cell leukemia was reduced. Adenosine deaminase activity in the sera of 2 patients with smoldering adult T cell leukemia was more elevated, with exacerbation of the disease. It is difficult to grade the extension of the tumors in plaque stage mycosis fungoides and smoldering adult T cell leukemia. To know the progression of the disease is critical in determining its management. These results indicate that adenosine deaminase activity in serum is one of the reliable indicators for the grading of mycosis fungoides and adult T cell leukemia.
