Mixed ethnic backgrounds make it that much harder to find a bone marrow transplant – MLive.com

ANN ARBOR, MI They searched the world for a match.

Bennett Sevack needed a bone marrow transplant. He was diagnosed with myelodysplastic syndrome after treatment for chronic lymphocytic leukemia. But there was no match for the Ann Arbor resident in the international registry.

So, his family started making calls.

Doctors first tried his siblings and cousins. When that didnt work, his sisters, friends and family spent six weeks calling and sharing flyers with synagogues around the world to encourage people to join the bone marrow registry, hoping someone with Sevacks Sephardic and Ashkenazi Jewish background would be willing to donate.

By fall, a partial match was found in an Italian obstetrics hospital in an umbilical cord blood sample. Soon after, another cord blood match was found in the U.S. It was enough to perform a transplant.

Sevack has gained an intense appreciation for donors.

You can save somebodys life..." he said. Its a blessing to do.

Finding an acceptable bone marrow donor is a challenge in general, but its that much harder for people of color and patients of complex ethnic backgrounds like Sevack, according to health care providers and families whove embarked on far-reaching searches for a match.

A white person has a 77% shot at finding a matching donor, according to Be The Match, a widely used donor registry. A black persons chances are 23%. For people of mixed backgrounds, the search can become more complex.

Part of the issue is the relatively narrow population of donors in the registry. Another part is the science: Certain HLA types, the protein that needs to match in bone marrow transplants, are more unique to specific backgrounds.

Sevacks transplant was completed in October 2019 more than three years after his initial diagnosis, and four months after getting news that he would definitely need a transplant.

He spent eight weeks healing from his transplant and two weeks healing from a bout of graft-versus-host disease in the hematology oncology clinic on the seventh floor of Ann Arbors C.S. Mott Childrens Hospital.

On the same floor, a 9-year-old Ann Arbor-area patient undergoing chemotherapy for acute myeloid leukemia is in the same predicament that Sevack once faced. She may need a bone marrow transplant as well, but a donor match her ethnic background is Cantonese, Hispanic and Caucasian has yet to be found in the registry.

The search

Genetics play a major role in finding a good match, said Mark Vander Lugt, a pediatric bone marrow transplant specialist at C.S. Mott working with the 9-year-old. People get four HLA types from each parent, meaning donors need to match in at least six spots, though sometimes a stronger match is required.

You get combinations that are hard to find in the registry because of that, Vander Lugt said.

Not everyone needs a transplant once theyre diagnosed. Doctors often treat blood cancers and related illnesses with chemotherapy first killing off the bad cells and waiting to see if healthy cells regenerate. If they dont, a transplant replaces the bone marrow, where blood stem cells are made.

The registry is so low on certain populations that some began taking matters into their own hands. Athena Asklipiadis founded Mixed Marrow, a nonprofit that conducts outreach to encourage multi-ethnic bone marrow and blood cell donations. She said the misconceptions of donation is one of the largest challenges in getting people registered. She started by reaching out to Facebook groups and college clubs on the West Coast, where she is based. Eventually, families began reaching out to her to help in the donor search.

People use this phrase, When theres a cure for cancer or If theres a cure for cancer, Asklipiadis said. But these are actual blood diseases and cancers that are curable. Theyre curable by the selflessness of a donor and thats the beautiful thing about it.

Sevacks sister Laurel Bernstein was part of the group of relatives and supporters who called synagogues in search of donors. She estimated they called hundreds of people and added more than 1,000 to the donor registry while searching for Sevacks match.

The nine of us all felt so energized by what happened, Bernstein said. "We had not finished calling the list, even though we got the match. We went through to the end of the list to help pay it forward, to help other people, to get that much more DNA into the database.

The transplant

For Sevack, it was umbilical cord blood that saved his life. DNA from the two samples created enough HLA type matches to begin the transplant.

Vander Lugt said the preferred transplant method is still donor transplants, because cord blood units are smaller and in more limited supply than donor cells.

Misconceptions of transplants are another roadblock. A bone marrow harvest in which a donor undergoes surgery to collect marrow from the hip is widely believed to be painful. But experts describe the process as a mild discomfort with a two-to-three day recovery time, instead.

And direct harvest is no longer the only method. Many hospitals also practice apheresis, which collects the peripheral blood that can generate new bone marrow through a process that looks like dialysis. Theres no surgery involved.

Choosing between the two collection processes is based on multiple factors, including the health of the patient undergoing general anesthesia and doctor and donor preference, Vander Lugt said.

The value

Fear of the unknown is what affected Sevack the most going into treatment. He said he had an anxiety breakdown the morning of his transplant, when he realized what was about to happen.

My heart was to the moon, Sevack said. I was fully dressed and every part of me was drenched. In about eight minutes I had gone through this journey of fear because the reality of what was going to come was upon me. (My wife) calmed me down, I changed my clothes and this journey began. Theres been plenty of times when Ive been scared to death.

Finding a transplant match taught his wife Phyllis Sevack the importance of facing each day separately. Fighting cancer was about healing every day making big battles smaller.

The reality of it hits all at once, Phyllis Sevack said. "I wouldnt want anybody to be afraid to go through it because it is every day take it day by day. And as soon as Bennett got over that hes not doing everything on one day, (he got better mentally).

Now at home, Bennett Sevack may take a year to fully heal. He looks forward to small improvements in his quality of life, like an expanded diet and doing his own grocery shopping at Meijer, he said.

Even the routine blood and platelet donations he received in treatment were invaluable to him. They saved his life.

Every day, theyd give me sacks of stuff that made me sick to think about it, Sevack said. It was someones donation that was given, that was literally giving me life. People who donate would do an amazing service to someone. You may not know who that is but its somebody.

Potential donors can begin the registration process by filling out a questionnaire about their medical history at bethematch.org. A cheek swab will confirm whether you meet the medical guidelines for donation. You may remain on the registry for years before a match is found. More information is available here.

Wolverines for Life and the Michigan Medicine Bone Marrow Transplant department are hosting a registration drive from 10:30 a.m. to 5 p.m. Tuesday, Feb. 18 at the Pierpoint Commons lobby, 2101 Bonisteel Blvd., Ann Arbor.
