Chinese guidelines recommend AZA or MMF for maintenance of remission in MPO-ANCA-associated glomerulonephritis patients.[13] A Study revealed the high 5-year patient and renal survival rates in Chinese MPA patients who received glucocorticoids plus MMF regimen for inducing and maintaining remission.[14] After receiving the patient consent, we finally applied low-dose glucocorticoids combined with MMF to maintain remission. Here, MPO is linked to glomerulonephritis.
