Patients undergo monthly health checks and have their blood and urine tested by a real-time PCR method, with TaqMan probes (BioRad, USA). If at least one of the two specimens (blood or urine sample) is positive for JCV (when JCV is quantified in blood or urine samples at > 250 copies/mL), the patient is confirmed to have JCV infection in any part or tissue of the body. Factors of JCV infection, such as age, gender, donor source, and immunosuppressive therapy, along with demographic and clinical data and JCV infection status, were analyzed using multivariable Cox-regression analysis. The estimated glomerular filtration rate (eGFR) was selected as an indicator of kidney function, and the difference in eGFR between JCV-infected patients and non-infected patients was compared using the t-test. This study was approved by the Research Ethics Committee.Results: JCV was detected in 71.3% of kidney transplant patients. Differences in eGFR were observed between the JCV-infected and non-infected patient groups (64.47± 25.70 and 70.89± 28.80 mL/min/1.73 m2 for each group; independent t-test; t=− 6.079; p=0.00). Factors such as kidney donor (HR=0.086; 95% confidence interval [CI]: 0.008– 0.936; p=0.04), tacrolimus trough level (HR=1.083; 95% CI: 1.069– 1.097; p=0.00), mycophenolate dose (HR=1.002; 95% CI: 1.002– 1.001; p=0.00) and prednisone dose (HR=1.001; 95% CI: 1.000– 1.001; p=0.00) in the trio of immunosuppressants tacrolimus + mycophenolate mofetil (MMF) + prednisone (multivariable Cox-regression analysis) are potential risk factors for JCV infection in renal transplantation. JCV infection in kidney transplant patients lowers the eGFR, leading to decreased transplant kidney function (independent t-test, p=0.00).Conclusion: The level of JCV infection in kidney transplant patients in our study is quite high (71.3%). Using an immunosuppressive regimen that uses the trio of immunosuppressants tacrolimus + MMF + prednisone, and having a donor source element are potential risk factors for JCV infection in renal transplantation. The function of the transplanted kidney is reduced by JCV infection in kidney transplant patients in the short term. The timely diagnosis and treatment of JCV can ensure the stable and long-term function of transplanted kidneys in kidney transplant patients.Keywords: urinary tract infection, polyomavirus, JC polyomavirus, kidney transplant, Vietnam |
