A minimal change disease compatible with C1q nephropathy in a paediatric patient. Evolution and treatment of a difficult pathology

摘要

C1q nephropathy is a controversial disease as some authorsconsider it to be indistinguishable from minimal change disease (MCD), while others believe it is a between minimalchanges and focal segmental glomerulosclerosis (FSGS).1,2Thecriteria for diagnosis of the disease include predominant C1qdeposits by immunofluorescence and no clinical or laboratoryevidence of systemic lupus erythematosus.3,4Microscopically,in contrast to lupus, there should be no tubulointerstitial disease in C1q nephropathy.
