摘要：

We studied a well-selected population of patients with active rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE) without immunosuppressive therapy. Control and patient peripheral blood mononuclear cells (PBMC) were incubated with IL-1 &#103, IL-10, TGF- &#103 or LPS for 20 h and the in vitro basal and stimulated secretions of IL-6, TNF- &#102, IL-1 &#103 and IL-1ra were measured by ELISA. We found that in the SLE patients the basal secretion of IL-6 was significantly lower and that of IL-1ra significantly higher than in control subjects, while in the RA group the basal IL-1ra secretion was higher than in healthy subjects. SLE and RA PBMC responded to LPS and IL-1 &#103 reaching higher cytokine secretion values than controls. The in vitro response of SLE and RA PBMC to TGF &#103 was normal, while that to IL-10 was defective: IL-10 was able to stimulate the production of IL-6 and IL-1ra in PBMC from normal subjects, but it was unable to enhance IL-6 secretion in RA cells and it was also completely ineffective in inducing IL-1ra secretion in both SLE and RA PBMC. Our work add new data useful for the evaluation of IL-10 and IL-1ra as therapeutic agents in rheumatic diseases.
