Urinary Markers of Podocyte Dysfunction in Chronic Glomerulonephritis.

Adv Exp Med Biol 2021 ;1306:81-99

Tareev Clinic, Department of Nephrology, Sechenov First Moscow State Medical University, Moscow, Russia.

Chronic glomerulonephritis (CGN) is a disease with a steady progressive course that involves the development of nephrosclerosis, which is especially evident in clinical courses with incidences of high proteinuria (PU). Currently, proteinuria is considered the main laboratory feature (sign) of CGN activity and progression because proteinuria is closely related to the process of tubulointerstitial fibrosis, which is correlated with the grade of renal insufficiency. The injury to podocytes, which are key components of the filtration barrier, plays a central role in proteinuria development. Read More

Monoclonal gammopathy of renal significance: Early diagnosis is key.

Nefrologia 2021 Apr 3. Epub 2021 Apr 3.

Nephrology Department, Carlos Haya Regional University Hospital and University of Malaga, IBIMA, REDinREN (RD16/0009/0006), Malaga, Spain. Electronic address:

Monoclonal gammopathy of renal significance is a clinical-pathological entity grouping renal disorders secondary to the secretion of a monoclonal immunoglobulin synthesized by a B-cell-derived clone and/or plasma cells in a patient with no diagnostic criteria for multiple myeloma. This term applies to a concept recently introduced owing to the need to differentiate this entity from monoclonal gammopathy of undetermined significance, given the negative prognostic impact of its high morbidity and mortality resulting from both renal and systemic involvement, occasionally even progressing to advanced chronic kidney disease. The renal damage occurs via both direct pathogenic mechanisms, with the deposition of the monoclonal protein in different renal structures, as well as indirect mechanisms, acting as an autoantibody provoking dysregulation of the alternative complement pathway.
