Some laboratories have recently focused on the failure of IL-2 function in T lymphocytes of severely burned patients. Since it is known that PGE inhibits the production of human IL2, the authors tested the sensitivity of lymphocytes from the burn patients to induction of receptors for IL2, in the presence of indomethacin. At the time of the patients' immunosuppression (days 10 to 40), the decreased percentage of IL2R-bearing cells was not augmented by IM. On the first day, however, IM did augment the percentage of IL2R-positive cells. This indicated that endogenous PG production in PBMC was active on the first day but not at the time of immunosuppression. A biphasic release of eicosanoid metabolites in burn patients was reported to be very high on day 1 and was then exhausted. Our findings are consistent with this pattern.
