The aim of this study was to assess toxic effects of systemic lupus erythematosus (SLE) serum on blood peripheral mononuclear cells from healthy donors and to evaluate if complement activation was involved. Monocytes from a healthy donor were incubated with 20 sera from ten SLE patients in both high and low disease activity states. After incubation non-adherent cells were analysed by flow cytometry. Serum from six SLE patients induced an increased cell death, four in active disease only, one in the inactive state and one in the active and the inactive state. Five of these sera, three with high and two with low disease activity, induced an increased apoptosis in the monocytes. Proportion of apoptotic cells correlated inversely with C1q and C3 concentration in the active disease sera, but not with disease activity as evaluated by SLEDAI. Apoptosis could be induced by addition of active C1s or antigen/antibody complexes to normal serum before incubation. Serum with complexes added induced increased tumour necrosis factor-alpha secretion from mononuclear cells, but SLE patient sera did not. The results demonstrate that the toxic effect of serum from SLE patients on healthy monocytes is explained by induction of apoptosis. The induction process is suggested to be connected with complement activation in the serum.
