BackgroundBK virus (BKV) is known to be associated with nephropathy. Here, we investigated the relationships between BKV levels, T-cell activation, and kidney function in kidney transplant recipients.Materials and methodsIn renal transplant patients and controls, urine BKV levels were detected by quantitative real-time PCR, and the percentage of activated T lymphocytes in blood was determined by flow cytometry. The correlations between viral load, activated T cell percentage, and renal function were determined.ResultsUrine BKV viral loads and the activated T cell percentage were significantly elevated in transplant recipients. Correlational analysis indicated that transplant recipients that had BKV levels of more than 106 copies/mL and an activated T lymphocyte percentage of less than 20% were likely to have poor renal function.ConclusionsUrine BKV levels and the percentage of activated T lymphocytes can be used as clinical indices to optimize the dosage of immunosuppressive drugs.
