South Africans in need of life-saving stem cell transplants face an uphill battle due to a high rate of donor attrition. While more than 30 000 South Africans registered as stem cell donors in 2023, a 43% increase year-on-year, more than half of matched donors changed their minds when they received the call.
Palesa Mokomele, Head of Community Engagement and Communications at DKMS Africa, says that donor attrition reduces the chances of survival for many patients. “Unlike other medical donations, such as donating blood, which take place immediately, stem cell donation is a multi-stage process, meaning that those who have registered may be contacted weeks, months, or even years after they have signed up if they are a possible match for a patient. “The uncertainty around whether and when they will be called on to donate therefore impacts donor availability.”
“If notified, they will be asked to undergo confirmatory typing to determine whether they are the best match for the patient and healthy enough to donate. It is usually at this point that they decide whether to proceed with the donation or not,” shares Mokomele.
“Finding a matching stem cell donor is already like searching for a needle in a haystack, so when they choose not to follow through, it further delays the process of locating suitable donors while also increasing wait times for transplants – putting patient survival at risk,” she points out.
To prevent this and help give patients a second chance at life as fast as possible, Mokomele urges those who have registered to regularly update their donor profile to reflect their current health status and availability. “Although it can take some time between registering and receiving the call that you’re a match, it is well worth the wait.”
Twenty-five-year-old Amahle, who recently answered the call, concurs, saying, “I couldn’t believe I was going to give another person a chance to live a healthy life.”
After receiving the news, she underwent confirmatory typing and a preliminary health check. She was also given a detailed briefing call on what to expect.
As with most cases, a Peripheral Stem Cell Donation was required, which is similar to a blood donation in 90% of cases. Blood is drawn and passes through a machine (apheresis machine) that collects the stem cells after which the rest of the blood is returned back into the body. This procedure does not require anaesthetic or admission to hospital and is normally completed within four to six hours. To help Amahle generate sufficient stem cell quantities, she was injected with a hormone-like substance called G-CSF in the lead up to the donation so her body can produce more stem cells for her genetic twin. G-CSF is safe and is a significant part of the process.
Finally, the big day arrived and although she was a ball of nerves (especially given her fear of needles), she pushed through. “I was strong. I knew I needed to continue because soon I was going to save a life.”
“We applaud Amahle’s selfless act. It is moments like these that remind us of the profound impact each individual can have on another’s life. At the same time, however, we are forced to acknowledge the sobering reality that 56% of registered donors drop out. With every registration, there is hope. But hope alone is not enough. Action is what truly makes a difference. We, therefore, urge South Africans between the ages of 17 and 55 who are in good health to not only register as a stem cell donor but to act when the call for donation comes,” concludes Mokomele.
