Collagenofibrotic glomerulopathy in a kidney transplant recipient: A first report

Area of Science:

• Nephrology
• Pathology
• Genetics

Background:

• Collagenofibrotic glomerulopathy (CG) is a rare glomerular disease characterized by abnormal collagen type 3 deposition.
• It typically presents with proteinuria, hematuria, and progressive renal dysfunction.

Observation:

• This study reports the first documented case of CG in a kidney transplant recipient.
• The recipient had underlying kidney disease of unknown etiology prior to transplantation.

Findings:

• Diagnosis of CG is confirmed by electron microscopy, revealing characteristic curved, comma-like, banded collagen type 3 fibers (40-65 nm periodicity) in glomeruli.
• The presence of CG in a transplant recipient suggests potential implications for graft survival and management.

Implications:

• This case highlights the importance of considering CG in transplant recipients with unexplained renal dysfunction.
• Further research is needed to understand the pathogenesis and optimal management of CG in the context of kidney transplantation.
