Fate of full‐house immunofluorescence staining in renal allograft: A case report. Issue 11 (11th September 2019) - Sawada, Anri
Abstract : Here, we report the case of a patient with renal allograft with full‐house immunofluorescence staining in the zero‐hour biopsy. Full‐house immunofluorescence staining is a well‐known characteristic of lupus nephritis. Previous studies have reported patients with full‐house immunofluorescence staining, but without other symptoms or serological findings; this condition is referred to as full‐house nephropathy. We identified only one case out of 2203 zero‐hour biopsies over 13 years. Zero‐hour biopsy presented no glomerular changes but showed full‐house immunofluorescence staining. Electron microscopy revealed a nonorganized electron‐dense deposit mainly in the mesangial lesion. Systemic lupus erythematosus (SLE)‐associated antibodies were negative, and complement deficiency was not observed in the donor patients. Deposition of immunoglobulin and complement levels markedly decreased within 1–3 years post transplantation. Neither donor nor recipient developed clinical or biological features of SLE; they showed good renal prognosis.
