If you are a bone marrow transplant recipient with symptoms of GvHD, talk to your doctor as soon as possible. During your visit, tell your doctor about all of your symptoms, no matter how minor they may seem.
If your doctor suspects you have GvHD, you will receive a blood test. This test will look for high levels of white blood cells, which usually indicate an infection. If your test shows a high white blood cell count, you may need a tissue biopsy.
The biopsy is usually performed while you are under sedation. It can also be performed with just a local anesthetic. A small piece of tissue will be removed from the area affected by GvHD. It will then be sent to the lab and tested for abnormalities. In many cases, a urinalysis urine test will also be used to detect signs of infection. Urine tests can be used to rule out conditions such as diabetes or bladder infections. The primary treatment for GvHD is prescription immunosuppressants.
These drugs reduce the immune response of the donor cells. They are usually prescribed in the form of intravenous or oral steroids. Corticosteroids are often prescribed to treat chronic GvHD, along with the following medications:. Preemptive treatment with immunosuppressant medications may reduce the risk of GvHD after transplantation.
These drugs are usually started before the transplant. Your doctor may recommend that you continue to take them for several months after the transplant is complete. At one year, most recipients will have formed new T lymphocytes that match the donor cells. People who do not enter a state of tolerance may need to continue taking immunosuppressants for a longer period of time.
Bladderwrack is an edible brown seaweed that has been used as a natural medicine for centuries. The release of pro-inflammatory cytokines increases the expression of receptors on antigen-presenting cells APCs , enhancing cross presentation of minor histocompatibility antigens to donor T-cells. Donor T-cells proliferate and secrete additional inflammatory cytokines, such as TNF. Target organ damage is the consequence of both cellular effectors and soluble factors like TNF. Pruritus sometimes precedes development of skin GVHD rash.
Abdominal cramping, loose stools, watery or bloody diarrhea should prompt further work-up. A thorough skin exam is an important aspect of every encounter in the at risk patient. A maculopapular rash is stereotypical, but sometimes erythema is the presenting finding. Rash involving the palms or soles in the at-risk patient is usually GVHD. Total bilirubin levels are mandatory as part of the acute GVHD staging. Eosinophilia on a complete blood count differential, while non-diagnostic, can be a clue to GVHD presence or impending onset.
This recently published large study from a single center confirmed and extended prior observations. Of note, recipient age was not a statistically significant risk in this study.
Excellent review of settings in which GVHD can develop, other than allogeneic bone marrow transplantation. Comprehensive state of the art review of GVHD pathophysiology, prevention, treatment, and supportive care recommendations.
This paper demonstrated that plasma GVHD biomarker concentrations measured at onset and during treatment in a multi-center study can predict treatment response and survival. J Clin Oncol. Recent comparative analysis demonstrated similar rates of acute GVHD after haploidentical transplants given post-transplant, high dose cyclophosphamide when compared to conventional related and unrelated donor transplants.
Highly cited paper describing expected treatment outcomes for patients treated for acute GVHD at a single center. Recent analysis of factors predictive for response and survival from a multicenter study of novel GVHD treatments. Pidala, J, Anasetti, C.

Acute graft-versus-host disease What every physician needs to know about acute graft-versus-host disease: Acute graft-versus-host-disease acute GVHD occurs when lymphocytes from another person are able to survive and proliferate in a patient; it is one of the most serious complications of allogeneic bone marrow transplantation BMT. The risk of acute GVHD is related to many clinical factors including:.

What conditions can underlie acute graft-versus-host disease: When do you need to get more aggressive tests: What imaging studies if any will be helpful? Specifically, the immune cells known as T cells are involved. Fred Hutch researchers have taken their new knowledge to the laboratory to tweeze apart the T cells that fight cancer from those that trigger GVHD, and their results have already translated into new clinical trials. One such trial spearheaded by Drs. Lee, Flowers and their colleagues are also conducting several studies testing promising new treatments for chronic GVHD, a next generation of therapies with greater precision to target the disease-causing immune cells.
The build-up of those proteins causes cells to die. To date, proteasome inhibitors have shown promise for patients with blood cancers. Lee and her colleagues have reason to believe the drugs also could combat the immune cells responsible for GVHD. 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. Grappone encourages other patients facing a transplant to do their own research about GVHD ahead of time, to know what they might be getting into. She has a Ph. Donate Now.
