Popis: Introduction: Kidney allograft survival has increased significantly in the past few decades. However, the more potent immunosuppression has also resulted in a higher incidence of infections including BK virus nephropathy (BKVN). The profile of kidney transplant (KT) recipients including age, basic kidney disease, comorbidities, dialysis vintage, and type of kidney donor in India is different from that of high-income countries. There are very few studies on the incidence and outcomes of BKVN from India. We studied the incidence, clinical features, and the impact of a screening strategy on patients with BKVN at our center. Materials and Methods: This was a single-center retrospective record-based study. We screened the medical records of all KT recipients at our center from March 2012 to December 2020 for patients who were diagnosed with BKVN. We compared the incidence of BKVN before and after the implementation of a proactive screening strategy in 2017. Results: From March 2012 to December 2020, a total of 212 KTs were performed at our center. Twenty-eight patients were diagnosed to have BKVN at this time. The incidence of BKVN in our study was 13.2%. The incidence of BKVN before routine screening was initiated at our center was 11.3% whereas it was 13.6% after routine screening was initiated. Graft loss from BKVN was 7.14%. Conclusion: The incidence of BKVN at our center is higher than previously reported in India; however, the rate of graft loss is low. A proactive screening strategy using nucleic acid test may allow early detection of BKVN and may have a beneficial impact on graft outcomes.
