Differential interleukin (IL)‐6 and IL‐10 serum concentrations among different study groups. Serum IL‐6 (a) and IL‐10 (b) levels in healthy controls (n = 6), remission systemic lupus erythematosus (SLE) (n = 6), active SLE (n = 6) and posterior reversible encephalopathy syndrome (PRES)/SLE (n = 14) were measured by cytometric bead array. Bars represent mean ± standard error of the mean (s.e.m.) of each cytokine concentration in each group. P‐values were considered significant at ≤ 0·05.
