title: Diagnosis of renal allograft rejection by analysis of fine-needle aspiration biopsy specimens with immunostains and simple cytology.
abstract: Fine-needle aspiration biopsy specimens of renal transplants were analysed by means of commercially available monoclonal antibodies and an immunoperoxidase stain. Three cellular features associated with acute cellular rejection were identified--heavy infiltrates of activated T cells or large mononuclear cells strongly expressing HLA-DR antigens, and HLA-DR expression by renal tubular cells. A combination of semiquantitative scores for these features correctly identified rejection in 32 of 34 cases, with no false positives in cases of cyclosporin nephrotoxicity or stable graft function.
