MANRIQUE, Joaquín  e  CRAVEDI, Paolo. Role of monoclonal antibodies in the treatment of immune-mediated glomerular diseases. Nefrología (Madr.) [online]. 2014, vol.34, n.3, pp.388-397. ISSN 1989-2284.  https://dx.doi.org/10.3265/Nefrologia.pre2014.Feb.12506.

Non-specific immunosuppressants have represented for decades the only therapies for patients with immune-mediated glomerular diseases. These treatments, however, are associated with high rates of no-response and are burdened by toxicities that frequently offset the benefits of proteinuria reduction. Monoclonal antibodies targeting selective cell populations or mediators implicated in the pathophysiology of glomerular diseases have recently become available. Rituximab, a chimeric monoclonal antibody against the CD20 antigen on B cells, safely reduced proteinuria in patients with nephrotic syndrome secondary to membranous nephropathy, minimal change disease, or focal segmental glomerulosclerosis. Its ability to reduce auto-antibody formation has been instrumental to treat also ANCA-associated vasculitis, lupus nephritis, and mixed cryoglobulinemia. Many reports have also documented the efficacy of the anti-C5 humanized monoclonal antibody Eculizumab to treat atypical hemolytic uremic syndrome, C3 nephropathy, and membranoproliferative glomerulonephritis. Thanks to these encouraging findings, monoclonals are becoming very helpful tools to treat patients with glomerular diseases. Moreover, thanks to their specific mechanism of action, these and other monoclonal antibodies are important in improving our understanding of the pathophysiology of glomerular diseases. Their still high costs, however, might represent a major hurdle for their widespread implementation for all patients in need.
