Figure 1:
Cytokine analysis of SLE SF samples (A) IL-17A, IL-6 and IL-10 cytokine levels were measured in SLE SF samples (n=17), matched serum samples (n= 14, combined with lines) and SF RA samples (n=10) and significant difference was analyzed using Mann Whitney test. Bars indicate median. (B) Spearman Correlations between IL17A, IL-6 and IL-10 levels in SF are displayed. (C) Spearman Correlation between IL-17A and IL-6 levels in serum vs SF. (D) IgA and IgM RF levels in serum and SF are shown. Red line indicates cut off: IgA RF = 18 IU/ml; IgM RF = 10 IU/ml)
