A renal transplant patient treated with tacrolimus and mycophenolate-mofetil (MMF) developed progressive graft function deterioration 10 months after transplantation. Biopsy of the graft showed severe, focally accentuated interstitial inflammation with focal tubulitis and tubular necrosis, and medium-severe interstitial fibrosis with focal tubular atrophy. Glomerular and vascular structures were preserved. On careful examination, in some sections, tubular epithelial cells showed a definite increase with deformation of the nuclear shape, chromatin irregularities with peripheral dislocation and inclusion bodies. These cytopathic changes suggested polyoma virus infection ("decoy cells"). Subsequent screening of the urinary sediment confirmed the presence of many "decoy cells". Immunohistochemical analysis of the biopsy showed many tubular cells were strongly positive for the SV 40 antigen, specific for BK polyoma virus. A diagnosis of interstitial nephritis due to BK polyoma virus was made, though the coexistence of cellular rejection could not be excluded. At variance with previous reports, our patient had not had repeated episodes of rejection before biopsy or heavy immunosuppressive treatment, such as ALG, OKT3, after transplantation. This case shows that even in the absence of vigorous anti-rejection therapy an immunosuppressive regimen based on tacrolimus and MMF may involve the risk of BK polyoma virus- associated interstitial nephritis.
