Parvovirus B19 (PVB19) has tropism to red blood cell progenitors and can be reactivated after organ transplantation. The aim of study was to describe clinical manifestations, laboratory findings, treatments used, and effectiveness in kidney recipients at Viet Duc hospital. A retrospective descriptive study was performed on 663 kidney recipients who were on regular follow-up from 2000 to 2018. PVB19 was detected by polymerase chain reaction PVB19-DNA. Effectiveness of therapy was assessed by Hemoglobin level. Nine out of 663 kidney recipients (1.4%) were diagnosed with PVB19-associated anemia. Eight of these 9 (89%) were diagnosed within the first 3 months following transplantation. All patients had normoscopic anemia; the average reticulocyte proportion and count were 0.15 ± 0.04% and 0.0039 ± 0.0011T/L, respectively. Graft dysfunction was observed in 4/9 (45%) patients. Treatment included reduction of immunosuppression, intravenous immunoglobulin (IVIG), and blood transfusion. All patients responded well to treatment except 1 (11%), who experienced relapse after using low dose of IVIG. PVB19-associated anemia usually occurred early after transplantation and was associated with very low reticulocyte proportion and count. Actual treatment was effective, but the risk of relapse was present.

Introduction: Coronavirus disease 2019 (COVID-19) is a life-threatening disease that was declared a pandemic in March 2020. Organ transplant recipients are vulnerable to infection and complications from COVID-19. The objective of this study was to investigate the rates of infection, mortality, and case-fatality ratios (CFR) in solid organ transplant recipients and patients on the waiting list for organ allocation in the period prior to the availability of specific vaccines.

Optimal fluid strategy for laparoscopic donor nephrectomy (LDN) remains unclear. LDN has been a domain for liberal fluid management to ensure graft perfusion, but this can result in adverse outcomes due to fluid overload. We compared postoperative outcome of living kidney donors according to the intraoperative fluid management.

Rationale & Objective: Valid measures of side effects are important to inform clinical use of calcineurin inhibitors (CNIs). This study sought to develop and establish the content validity of a PRO measure to capture side effects among kidney transplant recipients taking CNIs.
Study Design: Qualitative interviews for concept elicitation and cognitive debriefing.

Hepatitis C virus (HCV) infection is increasing in prevalence due to the growing opioid epidemic; however, its impact on pediatric kidney transplantation is unknown. This study compared kidney transplant outcomes between HCV-positive and propensity-score-weighted HCV-negative pediatric recipients. It also examined HCV-positive kidney utilization for pediatric transplantation in the United States.

Patients receiving kidney transplant experience immunosuppression, which increases the risk of bacterial, viral, fungal, and parasitic infections. Q fever is a potentially fatal infectious disease that affects immunocompromised renal transplant recipients and has implications in terms of severe consequences for the donor's kidney. A patient with acute Q fever infection following kidney transplantation was admitted to the Tsinghua Changgung Hospital in Beijing, China, in March 2021.
