A recent systematic review of biopsies taken from patients with COVID-19 showed various acute and chronic histological findings of the glomerulus, and vascular and tubule interstitial change [5]. They found that collapsing FSGS was the commonest glomerular lesion with a prevalence of 54%, whereas non-collapsing FSGS and minimal change disease had a prevalence of 2% each [5]. To the best of our knowledge, there are currently no reports on the association between anti-nephrin antibodies and collapsing FSGS or minimal change disease after COVID-19 infection. Here, NPHS1 is linked to focal segmental glomerulosclerosis.
