Polyomavirus BK (BKPyV)-associated nephropathy (BKPyV-nephropathy) remains a significant cause of premature kidney allograft failure. In the absence of effective antiviral treatments, current therapeutic approaches rely on immunosuppression (IS) reduction, possibly at the risk of inducing alloimmunity. Therefore, we sought to explore the long-term effects of a tailored viro-immunologic surveillance and treatment program for BKPyV on the development of alloimmunity and kidney graft outcome.

Methods: Clinical and genetic data of 28 APDS patients from 25 unrelated families were collected from fifteen Italian centers.
Results: Patients were genetically confirmed with APDS-1 (n = 20) or APDS-2 (n = 8), with pathogenic mutations in the PIK3CD or PIK3R1 genes.
Background: Current national and international guidelines (Italian Bone Marrow Donor Registry [IBMDR], World Marrow Donor Association [WMDA] standards) provide an indication for preoperative autologous blood donation (PAD) only in adult family and volunteer non-family donors in anticipation of bone marrow (BM) hematopoietic stem cell (HSC) donation to avoid the use of homologous transfusions. In addition, there is no clear guidance from the relevant scientific societies regarding pediatric and adolescent donors.
Material And Methods: To assess the actual use of PAD in pediatric (up to 14 years) and adolescent (aged 15-18 years) family donors in relation to BM HSC donation in the five years 2017-2021, a specific online questionnaire was administered to blood establishments and clinical units of pediatric transplantation programs responsible for BM HSC collection.
