Does Race Matter in Organ Transplants?

Understanding the Impact of Race on Organ Transplantation

More than 1,300 people in Colorado and Wyoming are waiting for a lifesaving organ transplant right now, a need that disproportionately affects communities of color. That gap raises a question: does race actually matter when it comes to organ transplants?

Short answer: Organ transplant candidates are never matched based on race or ethnicity, and people of different ethnicities frequently are matched successfully. However, transplant matches made within the same ethnic group can sometimes be more compatible. That’s why growing the pool of registered donors across every community, saves and heals more lives.

Here in Colorado and Wyoming, nearly 1,300 people are waiting for a lifesaving organ transplant. While the need for transplants touches people across all communities, almost 50% of those on the waiting list belong to communities of color.

What Is National Multiethnic Donor Awareness Month?

National Multiethnic Donor Awareness Month aims to raise awareness of organ, eye, and tissue donation across all ethnicities, as just one donor can save up to eight lives through organ donation and save or heal more than 75. In addition to raising awareness, it also aims to encourage donor registration and family conversations about donation as well as promote healthy living and disease prevention to reduce the need for transplants.

If Organs Aren’t Matched by Race, Why Do Same-Ethnicity Matches Work Better?

The reason is the Human Leukocyte Antigen (HLA). HLA antigens are proteins that most cells in our bodies contain. Our parents pass down these antigens as a unique set, regulating the immune system. HLA matching matters most for kidney transplants, the organ most needed by African American and Black patients, because HLA antigens tend to match less closely between Caucasian and African American candidates than they do within the same group.

Studies have shown that certain ethnicities face a higher risk of adverse outcomes, such as lower rates of organ transplantation and higher mortality rates post-transplant, which highlights systemic issues requiring equitable access to life-saving treatments for all patients, regardless of their racial background.

When it comes to kidney matching, which is the organ most needed by African American and Black patients, HLA plays a big role. This is due to HLA antigens not matching as well between Caucasian and African American candidates. Currently, African Americans make up more than 1/3 of the kidney transplant waiting list nationally, yet only around 13% of the general population. This creates a smaller pool of potential donor organs from African American donors, leading to African American transplant candidates relying on organs that do not match as well or having to wait longer for a more suitable match.

What’s Driving Transplant Disparities Between Racial Groups?

Several factors contribute to unequal transplant outcomes across racial and ethnic groups:

· Socioeconomic barriers: limited access to healthcare and unequal distribution of medical resources

· Genetic and immune-response differences: variation in HLA compatibility and immune response across groups

· Donor pool imbalance: communities that are underrepresented on the donor registry produce fewer matches

Understanding these factors is the first step toward policies and interventions that make transplant access more equitable for everyone.

Does Registering as a Donor Actually Help Close This Gap?

Yes. Because HLA compatibility improves the odds of a strong match within a community, growing the number of registered donors within underrepresented communities directly improves outcomes for patients waiting in those same communities.

This doesn’t mean donation is limited by race. Organ, eye, and tissue donation crosses every racial and ethnic line. It means a more diverse registry gives every patient, regardless of background, a better chance at a compatible match.

The importance of diverse communities registering as organ donors cannot be overstated. The need for lifesaving organ transplants affects people of all races, ethnicities, and ages. Organ transplantation knows no racial or ethnic boundaries; each donor can save and heal numerous lives. Embracing solidarity in organ donation bridges disparities and ensures a fair chance for every patient. A diverse and compassionate community makes a difference, an inclusive endeavor with no boundaries.

How Can I Get Involved This National Multiethnic Donor Awareness Month?

If you’re already a registered donor, take a moment this month to talk with your loved ones about your decision. If you haven’t registered yet, National Multiethnic Donor Awareness Month is a good moment to do so.

One decision can save and heal dozens of lives.

Thank you for your support of organ, eye and tissue donation. If you haven’t registered yet, register in Colorado or Wyoming today.
