Polyomavirus BK-specific immunity after kidney transplantation.
Failure to mount or maintain a protective immune response may influence the development of polyomavirus BK (BKV)-associated nephropathy (PVAN). However, limited data are so far available on BKV-specific immunity after kidney transplantation. BKV-specific cellular immune response was retrospectively analyzed in kidney recipients with or without BKV infection/reactivation by measuring the frequen...
متن کاملClinically Relevant Reactivation of Polyomavirus BK (BKPyV) in HLA-A02-Positive Renal Transplant Recipients Is Associated with Impaired Effector-Memory Differentiation of BKPyV-Specific CD8+ T Cells
Polyomavirus BK (BKPyV) frequently reactivates in immunosuppressed renal transplant recipients (RTRs) and may lead to graft loss due to BKPyV-induced interstitial nephritis (BKVN). Little is known on the differentiation of CD8+ T cells targeting BKPyV in RTRs. Here we investigated whether BKPyV-specific CD8+ T cell differentiation differs in RTRs with varying degrees of BKPyV reactivation and/o...
متن کاملPre-transplant immune factors may be associated with BK polyomavirus reactivation in kidney transplant recipients
BK polyomavirus (BKPyV) reactivation in kidney transplant recipients can lead to allograft damage and loss. The elements of the adaptive immune system that are permissive of reactivation and responsible for viral control remain incompletely described. We performed a prospective study evaluating BKPyV-specific T-cell response, humoral response and overall T-cell phenotype beginning pre-transplan...
متن کاملبررسی مولکولی فعالیت مجدد ویروس BK در ادرار بیماران پیوند کلیه
Background & Amis: BK polyomavirus (BKV) is common infection of childhood that persists in kidney epithelium. BKV reactivation characterized by viruria occurs in 35% to 57% of renal allograft recipients. BK virus was detected in serum samples in 6% to 29% of these patients. BKV-associated nephropathy occurs in as many as 8% of renal allograft recipients and may lead to . This study was carri...
متن کاملBK polyomavirus in kidney transplant recipients: screening, monitoring and clinical management.
BK polyomavirus (BKPyV) is a causal agent of nephropathy, ureteral stenosis and hemorrhagic cystitis in kidney transplant recipients, and is considered an important emerging disease in transplantation. Regular screening for BKPyV reactivation mainly during the first 2 years posttransplant, with subsequent pre-emptive reduction of immunosuppression is considered the best option to avoid disease ...
