Understanding the warning signs in the first months after transplantation — and why the differential diagnosis is decisive for graft survival. In brief. The risk of acute rejection is concentrated in the first three to six months after kidney transplantation. Four signs call for immediate contact with the transplant team: fever, falling urine output, pain over the graft, and sudden hypertension. But these symptoms closely… Read More »Acute rejection after kidney transplantation: warning signs

Around 80% of the world’s population carries BK polyomavirus in a latent state. In immunocompromised patients — kidney transplant recipients above all — reactivation can lead to a severe nephropathy. This guide covers the reference diagnostic methods, the thresholds that matter, and where rapid testing fits. Understanding BK virus BK polyomavirus (BKPyV) is a non-enveloped human polyomavirus with a circular double-stranded DNA genome, first described… Read More »How is BK virus infection detected? A complete guide

After a kidney transplant, BK virus can reactivate under immunosuppression and threaten the graft. SPyDiag’s aim is to make screening more accessible and to open a specific therapeutic route — two levers on the same problem. Informational content. The tools and treatments described here are complementary to hospital follow-up and to the protocols of the transplant centre. Medical decisions — which tests to run, how… Read More »BK virus: towards fewer kidney graft losses

UriFastBK aims to bring BK virus screening closer to the patient, so that monitoring can be more frequent and more responsive after kidney transplantation — alongside PCR, not instead of it. The problem: PCR is reliable, but not always actionable fast enough Reactivation of BK polyomavirus (BKPyV) is a major issue after kidney transplantation. It can progress to BK virus-associated nephropathy and threaten graft function,… Read More »How UriFastBK speeds up BK virus screening without a PCR platform
