How do I lower BK virus?

How do I lower BK virus?

BK virus proliferation is well controlled by the host cellular immune response. Therefore, currently, the best treatment is reduction in immunosuppression to restore the host cellular immune response.

How do you treat BK viremia?


  1. The goal in treating BKV infection is to eliminate the virus while preserving renal function and preventing acute or chronic rejection.
  2. Discontinuation of a single immunosuppression agent, antimetabolite (MMF or azathioprine), upon recognition of viremia has been used successfully to clear viremia (49).

What is the normal range for BK virus?

It is to be used for patients with a clinical history or risk factors for BKV-associated nephropathy. Reportable Range (lower and upper limits of quantification, analytical measurement range): Reportable range is from 1600 to 16,000,000 IU/mL.

What is a high level of BK virus?

A high level of BK viruria (≥ 25 million copies/mL) was found in 110 (30.1%) patients. At least 1 blood or biopsy BK test was available for all patients. Blood tests for BKV DNA were available for 361 patients, and 52 (14.4%) were positive.

Is BK virus common in kidney transplant patients?

BK virus (BKV) is a common infection encountered after kidney transplantation. BKV is associated with a spectrum of manifestations, starting with sub-clinical viruria, followed by viremia and BKV-associated nephropathy. Standard of care includes routine post-transplant screening for BK viruria and/or viremia.

Is BK virus fatal?

Based on these pathological results and the high sustained BKV viral load in his blood, we reached a diagnosis of BKV pneumonia. Viral infection can occasionally become life threatening among HSCT recipients. It is widely known that BKV can cause late-onset HC, but BKV-associated pneumonia is rare.

Can BK virus be cured?

A BKV infection may go away on its own without treatment. If you take antirejection medicine, your healthcare provider may change or decrease your dose. You may also need any of the following: Medicines may be used to decrease pain, help your immune system, or kill the BK virus.

What are symptoms of BK virus?

What are the Symptoms and Signs of BK Virus Infection?

  • Brown or red urine due to small amount of blood in the urine.
  • Difficulties with urination.
  • Fever, muscle pain or weakness.
  • Difficulty with breathing, cold and cough.
  • Worsening kidney function, due to kidney inflammation (interstitial nephritis)

How long does the BK virus last?

Mild cases of BK virus-associated hemorrhagic cystitis usually resolve spontaneously over a 2-week period with supportive care. With significant bleeding, severe urinary tract obstruction may occur because of clot formation.

How long does BK virus last?

What are the signs of BK virus?

What are the treatment options for bkvn and Aki?

In those with viremia and AKI or CKD, a kidney biopsy is necessary to confirm BKVN. With BKVN, the mainstay of therapy is the reduction in immunosuppression, although this may increase the risk of rejection and that risk in a life-sustaining allograft such as the heart, lung or liver must be weighed against the risk of progressive CKD.

What is BK virus nephropathy (bkvn)?

BK virus nephropathy (BKVN) was first described in a renal transplant recipient (RTR) presenting with transplant ureteric stenosis and was named after the initials of the patient. 1 After a quarter century, BKVN was increasingly recognized to result in allograft kidney damage, with the background of more potent immunosuppressive regimens.

What are the treatment options for BK virus associated nephropathy?

Sener A, House AA, Jevnikar AM, et al. Intravenous immunoglobulin as a treatment for BK virus associated nephropathy: one-year follow-up of renal allograft recipients. Transplantation2006; 81: 117–120 [PubMed] [Google Scholar]

What is the goal of BKV treatment?

The goal in treating BKV infection is to eliminate the virus while preserving renal function and preventing acute or chronic rejection. The treatment of BKV infection has centered on alterations in immunosuppressive therapy with or without antiviral therapies.
