MIF and glomerulonephritis: In contrast to our findings, Zwiech et al. concluded that levels of serum MIF were, indeed, significantly increased in subjects with glomerulonephritis (whether responsive or not to immunosuppressive treatment) in contrast to healthy controls (p = 0.036); however, the levels did not differ significantly between steroid-responsive and steroid-resistant cases, whether at baseline or after initiation of immunosuppressive treatment [14].
