ABSTRACT
C1q nephropathy is a rare glomerulopathy characterized by mesangial deposition of the complement component C1q. These deposits can be isolated or associated with immunoglobulins or complement fractions, which are observed by immunofluorescence or immunohistochemical microscopy. In ultramicroscopy, dense mesangial deposits and alterations of the podocyte are observed. Clinically it presents as a nephrotic syndrome (NS) or by alterations of the urinalysis such as proteinuria and/or hematuria in children and young adults. In light microscopy, it is expressed with a morphological pattern of minimal change disease (MCD), mesangial proliferative glomerulonephritis or focal segmental glomerulosclerosis (FSGS). The NS during its evolution usually evolve in steroid resistance or steroid dependency, often requiring the association of immunosuppressants to obtain remission. We report a 14 years old male with a history of NS and its evolution under various treatments during a 12-year follow-up.
