Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishINTRODUCTION: The purpose of this study was to describe and compare the renal histopathology and clinical course of simultaneous kidney-pancreas transplant (SKP) recipients with kidney transplant (KT) recipients with polyomavirus nephropathy (PVN). METHODS: Between 1997 and 2002, 20 patients (7 SKP, 13 KT) were diagnosed with PVN. Clinical characteristics and outcomes of PV-N were correlated with histopathologic examinations of renal allograft biopsy and compared between SKP and KT recipients. RESULTS: There were no differences in demographics between SKP and KT recipients with PV-N. The mean time to PVN was 611 (172 to 1174) days posttransplant in SKP and 343 (83 to 720) days posttransplant in KT (P =.05). The serum creatinine at the time of diagnosis was similar between SKP and KT recipients. All patients were treated with reduction in immunosuppression. After a median follow-up of 2 years, the patient survival was 71% in SKP and 100% in KT. Four grafts (57%) were lost owing to PVN in SKP group and three grafts (23%) were lost owing to PVN in the KT group. More patients (43%) in SKP had a history of acute rejection prior to diagnosis of PVN compared to KT (8%) and biopsy-proven tacrolimus nephrotoxicity prior to PVN was more common in SKPT (86%) than in KT (8%) patients (P <.05). SKP patients with evidence of diffuse fibrosis and high total sum scores at time of presentation all subsequently lost their grafts. CONCLUSIONS: SKP recipients with PVN had a worse clinical course than KT recipients.
