RESUMEN
OBJECTIVES: The present single centre study aims at analyzing the impact on renal allograft outcome of the important changes which occurred in the transplant population and immunosuppressive therapy during the last two decades. METHODS: From 2000 to 2013, 779 single kidney transplantations were performed on 635 patients who all received on an intent-to-treat basis steroids, a calcineurin inhibitor, mycophenolate mofetil and an induction therapy with either antithymocyte globulin or an antagonist directed to the interleukin (IL)-2 receptor. Uni- and multivariate analyses of patient and immunologic graft survival were conducted. RESULTS: The sole factor predicting patient survival is recipient's age: 10-year survival rates are 94·7, 81·6 and 57·9% for the <45, 45-60 and >60 years age groups, respectively (P<0·001). Peak (>50% panel reactive antibodies) anti-human leucocyte antigens (HLA) sensitization, cold ischaemia time and HLA-B and -DR mismatches (MM) influence graft outcome: at 10 years, the difference in 10-year survival rates is 5·9% between grafts from sensitized and not sensitized patients (90·9 vs 96·8%, Pâ=â0·002), 3·8% between grafts with <18 and â§18 hours cold ischaemia (96·6 vs 92·8%, Pâ=â0·003), 7·3% between grafts with no MM and either B or DR MM versus those with B and DR MM (96·8 vs 89·5%, Pâ=â0·002). CONCLUSION: In our single centre experience, graft survival was most strongly determined by HLA matching, offering excellent long term graft outcome to most patients.

A 31-year old man is addressed to the emergency department for fever, abdominal pain and vomiting. Laboratory tests reveal an inflammatory syndrome, thrombocytopenia, acute kidney injury associated with major proteinuria (more than 3 g/24 h). Evaluation will conclude to an acute interstitial nephritis and the serology is positive for Hantavirus. This clinical case illustrates differential diagnosis of acute renal failure and reminds the theory of hemorrhagic fever with renal syndrome : usual clinical presentation is "flu"-like symptoms, thrombocytopenia and acute renal failure. Hantavirus is endemic in some area in Europe and in Belgium. This clinical presentation should suggest the diagnosis if the patient has stayed in an endemic area.
