PLA2R1 and nephrotic syndrome: As regard to the delicate point of the indications to renal biopsy in MN, and coming back to our clinical case, herewith the view of the G. Bosco Hub Hospital in Turin: in patients who present with nephrotic syndrome and normal kidney function with positive anti-PLA2R serology and no evidence of another process to account for proteinuria renal biopsy could be postponed for at least 12 months taking the time to verify the effect of a complete RTX course.
