In Table 1, patients with crescents IgAN were more stages of E, S, and T scores of Oxford classification, hypocalcemia (p = 0.001), hypoalbuminemia (p<0.001), higher LDL (p = 0.002), lower HDL (p = 0.047), more daily urine protein (p = 0.005), higher urinary PCR (p<0.001), higher blood IgG (p = 0.034), lower IgM (p = 0.035), and more positive ANCA (p<0.001). This evidence concerns the gene CD40LG and Hypoalbuminemia.
