A happier time in 2009, when Laura Cuthbertson had just received a Kids Cancer Care Derek Wandzura Memorial Scholarship to pursue an education in nursing.

cure on the horizon. But with your support, Dr. Faisal and his research team may be able to stop the chances of graft versus host disease from ever happening in the first place.<\/span><\/p>\n

Laura is a 28-year-old nurse on long-term disability. She has been on steroids for over half of her life and will likely be on them for the rest of it. These powerful drugs, which she takes to manage the graft versus host disease (GvHD), have caused osteoporosis, high cholesterol and pancreatitis.<\/span><\/p>\n

Currently an out-patient at the Foothills Hospital, receiving an experimental therapy three to five times per week for GvHD, Laura is also a regular at the Chronic Pain Clinic. She also sees a psychiatrist and psychologist regularly to help her manage the pain.<\/span><\/p>\n

\u201cIt\u2019s an ongoing experiment to see what works and what doesn\u2019t,\u201d says Laura. \u201cSome days, I feel like I\u2019m falling apart. It\u2019s hard to hold it together emotionally, when you feel so lousy physically.\u201d<\/span><\/p>\n

GvHD is a serious health issue in patients who receive blood and marrow transplantation, a treatment commonly known as BMT, which frequently cures cancers and other disorders of blood. GvHD occurs when donor-derived blood cells in a patient see the patient\u2019s body as foreign and so triggers an immune response leading to various complications. For Laura, GvHD manifests itself in extremely painful sores throughout her mouth and esophagus.<\/span><\/p>\n

Laura Cuthbertson shares her story with scholarship recipients at the 2011 Kids Cancer Care Derek Wandzura Memorial Scholarship ceremony. A former licensed practical nurse, Laura is now on long-term disability because of health problems related to the BMT she received as a teenager while being treated for a high-risk leukemia.<\/span><\/figcaption><\/figure>\n

\u201cAbout 25 to 40 per cent of adult and pediatric BMT recipients are diagnosed with GvHD,\u201d says Dr. Faisal Khan, an associate professor in the departments of pediatrics; and pathology and laboratory medicine at the University of Calgary\u2019s Cumming School of Medicine. \u201cAbout 10 per cent of these patients die from GvHD and another 25 per cent suffer long-term complications and poor quality of life. That\u2019s f<\/span>ar too many.\u201d<\/span><\/p>\n

Working with the Tissue Typing Laboratory of Calgary Laboratory Services, Faisal and his research team at the University of Calgary are trying to reduce the risk of GvHD for young people like Laura by improving the screening and matching process of BMT donors.<\/span><\/p>\n

Traditionally, health care professionals have matched donors and patients based on five immunity-related genes to determine whether a donor is compatible and suitable for the BMT. A high incidence of GvHD, however; suggests that matching by these five immunity-related genes is insufficient. Over the last four years, Faisal\u2019s lab has identified distinct genetic variants and signatures, including the matching of 14 immune function genes, which may improve screening and outcomes for patients who already share the first five immunity-related genes with the donor.<\/span><\/p>\n

\u201cOur research has shown that matching these 14 genes in donors and patients reduces the risk of GvHD twofold, compared to transplants where these 14 genes are not matched,” says Faisal.
\nIf all goes well, within the next year or two, Faisal and his research team will be ready to launch a clinical trial to evaluate the new screening and matching system. But even at this stage, their research findings look promising. Faisal\u2019s research was named the most clinically relevant research in 2014 by the<\/span> American Society for Histocompatibility and Immunogenetics<\/a>, the governing body for all tissue typing laboratory testing facilities in North America. In 2013 and 2015, the findings were selected for a prestigious<\/span> American Society of Hematology<\/a> abstract achievement award.<\/span><\/p>\n

The hope is that the new screening process will offer doctors superior immuno-genetic information, so they are able to more accurately predict and pre-empt poor outcomes in BMT patients.<\/span><\/p>\n

\u201cThe perfect scenario is always to find a perfectly matched donor,\u201d says Faisal, \u201cbut in situations where an ideal donor isn\u2019t available, at least the health care team will have the information they need to anticipate the outcomes. They\u2019ll be in a better position to predict adverse effects, so they can introduce more rigorous monitoring of patients earlier and, if need be, administer pre-emptive treatments sooner.\u201d<\/span><\/p>\n

The immuno-genetic information gained through the new screening process may also help researchers and doctors predict which drugs will be most effective in enlisting the patient\u2019s own immune system to help attack and kill the cancer.<\/span><\/p>\n

With Faisal\u2019s research findings, we may one day see fewer BMT-related complications and health issues. It may lead to fewer relapses and reduced risk of GvHD for young people like Laura. The hope is that ultimately it will mean fewer deaths and healthier, happier lives after blood and marrow transplantation.<\/span><\/p>\n

Thank you for supporting Experimental and Applied Therapeutics research at the Childhood Cancer Research Program. You are helping researchers like Dr. Faisal Khan improve outcomes for BMT patients offering them hope for a healthy future.<\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
