Role of Serum and Urine Biomarkers (PLAR and THSD7A) in Diagnosis, Monitoring and Prognostication of Primary Membranous Glomerulonephritis.

Biomolecules 2020 Feb 17;10(2). Epub 2020 Feb 17.

Histopathology Unit, Department of Pathology, Faculty of Medicine and Health Science, Universiti Putra Malaysia, Serdang, Selangor 43400, Malaysia.

Differentiating primary and secondary membranous glomerulonephritis (MGN) using biomarkers for MGN is essential in patients' diagnosis, treatment and follow-up. Although biopsy has been the primary tool in making the diagnosis, not all patients can withstand it due to its invasive nature, and it cannot be used to monitor treatment. Hence, there is the need for less invasive or even non-invasive biomarkers for effective diagnosis, treatment monitoring and prognostication. Read More

Background: Membranous glomerulonephritis (MGN) is a common kidney disease. Despite many evidences support that many immune and inflammation-related genes could serve as effective biomarkers and treatment targets for MGN patients, the potential associations among MGN-, immune- and inflammation-related genes have not been sufficiently understood.

Methods: Here, a global immune-, inflammation- and MGN-associated triplets (IIMATs) network is constructed and analyzed. Read More

Treatment Patterns Among Adults and Children With Membranous Nephropathy in the Cure Glomerulonephropathy Network (CureGN).

Kidney Int Rep 2019 Dec 16;4(12):1725-1734. Epub 2019 Sep 16.

Division of Nephrology, Maisonneuve-Rosemont Hospital, Department of Medicine, University of Montreal, Montreal, Quebec, Canada.

Introduction: The 2012 Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guidelines for Glomerulonephritis recommend that patients with membranous nephropathy (MN) at risk for progression receive immunosuppressive therapy (IST), usually after 6 months of observation. A cyclophosphamide (CYC) or calcineurin inhibitor (CNI)-based regimen is recommended as first-line IST. However, the extent to which KDIGO recommendations are adopted in practice remains largely unknown. Read More

Resolution of syphilis-related rapidly progressive glomerulonephritis with penicillin therapy: Case report
.

Clin Nephrol 2020 Feb;93(2):106-110

Renal manifestations of syphilis are variable, with membranous nephropathy being the most commonly described lesion. Rapidly progressive glomerulonephritis (RPGN) is rare and there is only one case report in the literature describing syphilis-associated crescentic glomerulonephritis. We report a rare case of RPGN secondary to latent syphilis, which resolved with penicillin treatment in the absence of immunosuppressive therapy. Read More

Immune-Monitoring Disease Activity in Primary Membranous Nephropathy.

Front Med (Lausanne) 2019 8;6:241. Epub 2019 Nov 8.

Experimental Nephrology Laboratory, Biomedical Research Institute of Bellvitge (IDIBELL), Barcelona, Spain.

Primary membranous nephropathy (MN) is a glomerular disease mediated by autoreactive antibodies, being the main cause of nephrotic syndrome among adult patients. While the pathogenesis of MN is still controversial, the detection of autoantibodies against two specific glomerular antigens, phospholipase A2 receptor (PLAR) and thrombospondin type 1 domain containing 7A (THSD7A), together with the beneficial effect of therapies targeting B cells, have highlighted the main role of autoreactive B cells driving this renal disease. In fact, the detection of PLAR-specific IgG4 antibodies has resulted in a paradigm shift regarding the diagnosis as well as a better prediction of the progression and recurrence of primary MN.

Serum Levels of BAFF and APRIL Predict Clinical Response in Anti-PLA2R-Positive Primary Membranous Nephropathy.

J Immunol Res 2019 5;2019:8483650. Epub 2019 Nov 5.

Clinical Pathology Unit and Center for Molecular Medicine, Department of Medical and Surgical Sciences, University of Foggia, Foggia, Italy.

Primary membranous nephropathy (PMN) is a renal-specific autoimmune disease caused by circulating autoantibodies that target glomerular podocyte antigens (PLA2R/THSD7A). However, very little is known on the molecular mechanisms controlling B cell response in this nephropathy. The present study was aimed at correlating the serum levels of B cell activators BAFF/BLyS and APRIL with the presence of anti-PLA2R antibodies in PMN patients and with long-term clinical outcome.
