As shown in Table 4, the titer of serum anti-PLA2R Ab, the proportion of male patients, and the incidence of infection was significantly increased, while levels of serum albumin, baseline 25(OH)D, follow-up 25(OH)D, △25(OH)D levels, and serum calcium were significantly decreased in NR compared to the remission group (P < 0.05). This evidence concerns the gene PLA2R1 and infection.
