摘要
Serum concentrations of Interleukin-6 (IL-6) were determined in renal cell carcinoma patients treated with low-dose subcutaneous human recombinant interleukin-2 (rIL-2). In all patients, administration of rIL-2 resulted in a significant increase in IL-6 serum levels to peak values within 4 to 6 hours as measured by enzyme-linked immunosorbent assays (ELISA). Repetitive administration of rIL-2 induced significantly lower IL-6 serum peaks when compared to the initial administration of rIL-2. Cumulative IL-6 release, as expressed by the area under the concentration curve (AUC), appeared to be independent of rIL-2 dose distribution (10 million IU rIL-2/m2 versus 20 million IU rIL-2/m2), and IL-6 serum peaks showed no direct dose dependency. Prior rIL-2 immunotherapy had no measurable effect on rIL-2 induced IL-6 release, while steroids resulted in a significant suppression of secondary IL-6. Release of IL-6 did not correlate with response to rIL-2 therapy or survival of rIL-2 treated renal cell carcinoma patients.
