A 60yo otherwise healthy woman develops #nephrotic syndrome. Only putative trigger: first vaccination w/ Comirnaty 10 days before.

Biopsy shows IgAN with a podocytopathy resembling #FSGS.

Steroids and CNI are not tolerated.

1) how would you label the disease? Primary or secondary FSGS?
2) next treatment? Ritux?
