CRP levels were significantly elevated in renal vasculitis compared to focal segmental glomerulosclerosis (FSGS, p < 0.0001), immunoglobulin A (IgA) nephropathy (p < 0.0001), hypertensive nephropathy (p = 0.0025), lupus nephritis (p = 0.0003), membranous nephropathy (p = 0.0231), and minimal change disease (p = 0.0067, Figure 1A). The gene discussed is CRP; the disease is hypertensive nephropathy.
