How long can gvhd last

Graft-versus-host disease can be mild, moderate or severe. In some cases, it can be life-threatening. There is no standard regimen for the prevention of GVHD, and different combinations of medications are given at different institutions. Some common medications that are given to prevent GVHD include.

There are two main categories of GVHD: acute graft-versus-host disease and chronic graft-versus-host disease. Each type affects different organs and tissues and has different signs and symptoms. Patients may develop one type, both types, or neither type. This usually develops within the first days after transplantation, but it can occur later. Acute GVHD can affect the skin, the gastrointestinal tract or the liver.

Symptoms may include. Many patients who develop acute GVHD are successfully treated with increased immunosuppression in the form of corticosteroids medicines such as prednisone, methylprednisolone, dexamethasone, beclomethasone and budesonide.

Fred Hutch clinical researcher Dr. Marco Mielcarek is conducting research to treat not only transplant patients but their donors. Taking a different tack to prevent GVHD in this case, acute GVHD , Mielcarek is leading a new study that asks stem cell donors to take a two-week course of a statin, a class of drugs normally used to lower cholesterol.

If that result bears up in his current prospective study, in which donors are asked to take atorvastatin, the generic version of the brand-name statin Lipitor, before transplant, it could be a simple but important fix for the most deadly form of acute GVHD, Mielcarek said. A recent study led by Fred Hutch researcher Dr. Storb and his colleagues found that contrary to the common wisdom, getting GVHD did not make patients more likely to survive their cancer.

In fact, both acute and chronic GVHD were associated with lower survival rates. That surprise is common and difficult to avoid, Flowers said. Patients are primarily focused on surviving a disease that could take their lives in the next few months, she said. And even if they hear how common GVHD can be, they may have a hard time believing it will happen to them.

Greg Grappone just wants to be a regular dad. Focus on the donor Fred Hutch clinical researcher Dr. And eliminating GVHD — acute or chronic — is a reasonable goal, he said. Recently, though, that dogma is shifting. Researchers and physicians are realizing they can divorce the powerful graft-vs. Again, those efforts come back to quality of life for survivors, said Lee. We want them to have good quality of life in addition to not having their disease comes back, and a lot of that hinges on whether they get chronic GVHD or not.

At the Hutch, clinical researcher Dr. Marie Bleakley is leading studies that separate out some immune cells from the donor blood or bone marrow before the transplant. Those clinical trials are based on a growing body of research that has sifted out the specific cells and molecules responsible for triggering GVHD.

Researchers have observed that cord blood transplants, using blood cells from donated umbilical cords rather than blood stem cells from adult donors, result in lower levels of moderate to severe chronic GVHD — about 10 to 20 percent vs. Other studies have also found that giving patients the immune system-suppressing drug cyclophosphamide as a preventive measure drops the risk of chronic GVHD by about 50 percent. Flowers and her colleagues recently found that in addition to lower rates of chronic GVHD, the disease was shorter in recipients of cord blood transplant and in those who had received cyclophosphamide.

That will involve new blood tests to predict which treatment a given patient is likely to respond to, Hill said. But in parallel, researchers are also trying to identify targeted treatments that may work better for specific organs affected by GVHD, Lee said.

She and her colleagues at the Hutch are poised to launch a number of clinical trials testing therapies specifically for patients with just one form of chronic GVHD, such as scleroderma or lung GVHD. Those differences are likely part of the reason that combatting chronic GVHD has proven so difficult, Lee said. She has a Ph. Donate Now. Hutch News Stories.
