Implication

Case report reveals concurrent giant cell arteritis and anti-PLA2R membranous nephropathy in an older male, suggesting potential overlapping autoimmune pathways.

Key Points

  • To describe the clinical presentation, diagnosis, and management of concurrent giant cell arteritis and anti-PLA2R-positive membranous nephropathy in an older patient.
  • Clinical, biochemical, and histopathological evaluation of a 63-year-old male presenting with systemic inflammatory symptoms and nephrotic-range proteinuria (N=1).
  • Immunohistological confirmation of M-type phospholipase A2 receptor (PLA2R) in renal subepithelial immune deposits and therapeutic monitoring during corticosteroid treatment.
  • Diagnostic evaluation identified concurrent giant cell arteritis and membranous nephropathy with subepithelial PLA2R-positive deposits, accompanied by preserved renal function.
  • Treatment with corticosteroid therapy induced complete clinical and biochemical remission of both vascular and renal conditions.
