Fibrillary glomerulonephritis (FGN) is a rare glomerular disease characterized by the deposition of fibrils within the mesangium and glomerular basement membrane. Most cases are idiopathic, but it can be linked to autoimmune diseases, neoplasms, and infections. There is limited evidence on the best treatment approach, and many patients progress to end-stage kidney disease. The authors present a case of FGN in a patient with Sjögren's syndrome (SS) and primary biliary cholangitis (PBC), highlighting a successful clinical outcome.

This guideline provides consensus opinion on the investigations required for people presenting with suspected monoclonal gammopathy of renal significance to both nephrology and haematology physicians. The guideline discusses the principles of treating a patient with MGRS and provides recommendations for both supportive management and haematological therapy. It details the recommended on-going monitoring required for both specialty areas.

Fibrillary glomerulonephritis is a rare glomerular disease with some correlations between this condition alongside viral infections, malignancy, and autoimmune pathologies. However, the question regarding the pathogenesis is whether patients who develop fibrillary glomerulonephritis do so irrespective of these other pathologies or whether such pathologies induce fibrillary glomerulonephritis through an unknown mechanism. As such, attempts have been made to create associations with this disease to demonstrate further understanding.

Introduction: Fibrillary glomerulonephritis (FGN) is a rare form of glomerular disease that accounts for less than 1 percent of all renal biopsies. It is characterized by pathognomonic electron microscopy findings of fibrillar deposits in the mesangium and glomerular capillary walls. FGN was initially considered to be an idiopathic disorder.
