  • Title: Lymphocyte transformation test in drug-induced toxic epidermal necrolysis.
    Author: Roujeau JC, Albengres E, Moritz S, Piacentino A, Cuny M, Revuz J, Touraine R.

    Abstract:
    Lymphocyte transformation tests (LTT) to drugs remain widely used in drug reactions, despite controversies about their real usefulness. We tested the lymphocytes of 12 patients recovering from a drug-induced Toxic epidermal necrolysis (TEN). There was no difference between the amounts of thymidine incorporated when patients' lymphocytes were cultivated with culprit or innocent drugs. In both situations the lymphocytes from patients reacted like the lymphocytes from controls cultivated with the same panel of drugs. These negative results do not exclude that a hypersensitivity reaction may play a role in the physiopathology of TEN. Anyhow, they clearly indicate that testing lymphocyte transformation to drugs has no practical value in the diagnosis of TEN.
