Background: Crescentic glomerulonephritis with syphilis infection is rare, and the mechanism underlying the formation of glomerular capillary wall damage-induced crescent has not been elucidated.
Case Presentation: A 62-year-old Japanese male showed edema, eruption, and rapid deterioration of the renal function after an acute syphilis infection. A renal biopsy showed crescentic glomerulonephritis with C3 deposition in the glomerular capillary wall, and immunostaining for anti-Treponema pallidum antibody was weakly positive in some interstitium and one glomerulus.
Background: Urinary podocyte excretion is related to a reduction in glomerular podocyte numbers, glomerulosclerosis, and urinary protein selectivity. To elucidate the role of urinary podocytes in proteinuria and renal prognosis and to identify the factors that cause podocyte detachment, we examined urinary podocytes in 120 renal biopsy patients.
Methods: Podocytes were identified in urinary sediments stained with fluorescent-labeled anti-podocalyxin antibodies in ten high power fields.
