- Female Patient with Alport Syndrome and Concomitant Membranous Nephropathy: Susceptibility or Association of Two Diseases?(2017) VELOSO, Mariana P.; NEVES, Precil D. M. M.; JORGE, Lecticia B.; DIAS, Cristiane B.; YU, Luis; PINHEIRO, Rafaela B. B.; TESTAGROSSA, Leonardo A.; MALHEIROS, Denise M.; BALBO, Bruno E. P.; LERARIO, Antonio M.; ONUCHIC, Luiz F.; WORONIK, ViktoriaAlport syndrome (AS) is a disorder of collagen IV, a component of glomerular basement membrane (GBM). The association of AS and immunocomplex nephropathies is uncommon. This is a case of a 37-year-old woman with family history of X-linked AS, including 4 affected sons. This patient developed full-blown nephrotic syndrome along a 3-month period, a presentation not consistent with AS progression. This scenario suggested an alternative diagnosis. A kidney biopsy was therefore performed, showing membranous nephropathy (MN) in addition to GBM structural alterations compatible with AS. Whole exome sequencing also confirmed the diagnosis of X-linked AS, revealing a heterozygous pathogenic mutation in COL4A5. While a negative serum anti-phospholipase A2 receptor did not rule out a primary form of MN, it was also uncertain whether positive serologic tests for syphilis could represent a secondary factor. It is currently unknown whether this unusual association represents AS susceptibility to immunocomplex-mediated diseases or simply an association of 2 disorders. (C) 2017 S. Karger AG, Basel
