Treatment
The cornerstone of therapy is reduction in immunosuppression. A recent surge in BKVN correlates with use of potent immunosuppressant drugs, such as tacrolimus and mycophenolate mofetil (MMF). Studies have not shown any correlation between BKVN and a single immunosuppressive agent but rather the overall immunosuppressive load.
- No guidelines or drug levels and doses exist for proper reduction of immunosuppressants in BKVN
- Most common methods:
- Withdrawal of MMF or tacrolimus
- Replacement of tacrolimus by cyclosporine
- Overall reduction of immunosuppressive load
- Some cyclosporine trough levels reported to be reduced to 100–150 ng/ml and tacrolimus levels reduced to 3–5 ng/ml
- Retrospective analysis of 67 patients concluded graft survival was similar between reduction and discontinuation of agents.
- Single center study showed renal allografts were preserved in 8/8 individuals managed with reduction in immunosuppression while graft loss occurred in 8/12 patients treated with an increase in therapy for what was thought to be organ rejection.
Other therapeutic options include Leflunomide, Cidofovir, IVIG, and the fluoroquinolones. Leflunomide is now generally accepted as the second treatment option behind reduction of immunosuppression.

Famous quotes containing the word treatment:
“A regular council was held with the Indians, who had come in on their ponies, and speeches were made on both sides through an interpreter, quite in the described mode,—the Indians, as usual, having the advantage in point of truth and earnestness, and therefore of eloquence. The most prominent chief was named Little Crow. They were quite dissatisfied with the white man’s treatment of them, and probably have reason to be so.”
—Henry David Thoreau (1817–1862)
“[17th-century] Puritans were the first modern parents. Like many of us, they looked on their treatment of children as a test of their own self-control. Their goal was not to simply to ensure the child’s duty to the family, but to help him or her make personal, individual commitments. They were the first authors to state that children must obey God rather than parents, in case of a clear conflict.”
—C. John Sommerville (20th century)
“I will use treatment to help the sick according to my ability and judgment, but never with a view to injury and wrongdoing. Neither will I administer a poison to anybody when asked to do so, nor will I suggest such a course. Similarly, I will not give to a woman a pessary to cause abortion. I will keep pure and holy both my life and my art.”
—Hippocrates (c. 460–c. 370 B.C.)
