Abstract

Immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN) is a rare pattern of kidney injury and a progressive nephropathy characterized by the glomerular deposition of immune complexes and complement proteins. The IC-MPGN pattern of injury exhibits a membranoproliferative glomerulonephritis appearance by light microscopy and occurs secondary to various conditions or, more rarely, idiopathically, when no underlying etiology can be determined. Kidney biopsy is the only method for identifying IC-MPGN, distinguishing between IC-MPGN and complement 3 glomerulopathy (C3G), and for providing critical pathologic insights that guide further clinical evaluation for underlying etiologies and inform patient management. Given the progressive nature of IC-MPGN, it is crucial to identify patients early and to define the underlying pathophysiology for timely and appropriate treatment. However, several challenges remain in the accurate interpretation of kidney biopsy specimens and the effective treatment of idiopathic disease. In this commentary, two nephrologists and a nephropathologist review best practices in the clinical and histopathologic evaluation of IC-MPGN and discuss the central role of kidney biopsy in the differentiation of IC-MPGN and C3G. The challenges and considerations discussed are explored through an illustrative case of idiopathic disease, drawn from the authors' clinical experiences. Finally, remaining unmet needs are highlighted, and future perspectives on targeted treatments under investigation for patients with idiopathic IC-MPGN are provided.

期刊介绍: Advances in Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all therapeutic areas. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged. The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Advances in Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
