Multiple drugs: BK polyomavirus infection and lack of efficacy : case report.

A 51-year-old man developed a BK polyomavirus infection while undergoing immunosuppressive therapy for a kidney transplant.

The case highlights the lack of efficacy of immune-globulin in treating BK polyomavirus infection. [Extracted from the article]
