VMMU75_Characteristics of BK Virus Load and Role in Predicting BK Virus-Associated Nephrology in Patients Post Kidney Transplantation_Truong Quy Kien
Main Article Content
Abstract
ABSTRACT
Objective: The study aimed to analyze the load characteristics of the BK virus in serum and urine and its role in predicting BK virus-associated nephrology in patients after kidney transplantation.
Subjects and Methods: 360 kidney transplant patients at Military Hospital 103 were included in a prospective cross-sectional study. Realtime-PCR was used to measure BK viral load in serum and urine samples. Patients who met the biopsy criteria underwent the procedure according to the protocol.
Results: The study found that 56.7% of kidney transplant patients had BK virus infection, with 3.1% developing BK virus-associated nephropathy. BK virus infection was most prevalent between 3-6 months post-transplantation. A BK virus load in serum was exceeding 1.3. 104 copies/mL predicted BK virus-associated nephropathy with 81.8% sensitivity and 87.1% specificity. In urine, a BK virus load exceeds 1.5. 106 copies/mL predicted BK virus-associated nephropathy with 90.9% sensitivity and 67.9% specificity. BK virus load in serum was a better predictor than in urine.
Conclusion: BK virus load plays a role in predicting BK virus-associated nephrology with a cutoff of 1.3. 104copies/mL in serum and 1.5 .106 copies/mL in urine.
