Donated kidney wait list is not the only option
One woman’s transplant story: “The best kidney for me.”
Rachel Hornsby received a life-saving kidney transplant because of an organ donor, an excellent medical team — and her own take-charge approach to finding a kidney.
In the mid-1990s, Hornsby learned that she had polycystic kidney disease, a genetic disease that creates cysts in the kidneys. The diagnosis came after her 28-year-old sister died suddenly, and her autopsy revealed the disease. Hornsby’s mother was also diagnosed and started dialysis. In dialysis, a machine pumps a patient’s blood through a filter to remove toxins and waste products, something the kidneys normally do. Hornsby’s mother did not do well on dialysis, however, because her blood clotted easily, and she died at age 58, after a few years of treatment.
“I decided that I was going to arm myself with the best care and make sure that I knew everything I could about this disease,” said Hornsby, a Nashville, Tennessee, resident now in her 50s.
She sought out the Vanderbilt Center for Kidney Disease and nephrologist Talat Alp Ikizler, M.D. Ikizler knew that blood clotting is not typical in polycystic kidney disease patients, so he sent her to a blood specialist, which led to another diagnosis for Hornsby: another genetic disorder, factor V Leiden, which causes blood clotting. She inherited a gene for it from each of her parents. This explained why her mother did so poorly with dialysis — her blood vessels clotted at each site where a dialysis catheter was inserted.
Hornsby was in an ominous position. She has two genetic diseases, lost two family members whose conditions weren’t fully understood at the time, and she would certainly suffer the same blood clotting on dialysis that contributed to her mother’s death. Though many kidney transplant patients undergo dialysis while awaiting a donor kidney, Hornsby’s best hope was avoiding dialysis.
The kidney transplant wait list, vs. a live donor
In December 2013, Hornsby joined the national waiting list for a kidney. Her kidney function was at 20 percent. However, “I didn’t think about being on the list again from that point on,” Hornsby said, “because I knew that it could take between three to five years for the right match.”
More than 100,000 people in the U.S. need a kidney transplant. About 17,000 people receive a kidney each year; 13 people die every day waiting for one. Hornsby knew the odds were against her receiving a kidney from the wait list, which tracks organs donated at the time of someone’s death.
Hornsby contacted Dana Blayney, the living donor coordinator with Vanderbilt’s Live Donor program. She got more bad news. Tests revealed that she had very high antibodies, thanks partly to her pregnancy with twins. The boys had a different blood type from Hornsby, so her immune system reacted to what it perceived as a foreign threat by creating antibodies that will stay with her for life. Unfortunately, those antibodies were likely to perceive a donated organ as a threat and attack it. This would make her a difficult match with most kidneys.
Hornsby didn’t give up. She continued spreading the word that she needed a live kidney donation. A Facebook post prompted 21 people to offer to be tested as possible matches. Fourteen were tested; none were a good match. Hornsby realized that finding a well-matched kidney for a direct donation to her was very unlikely.
Paired donor “exchange” improves chances
Blayney suggested Hornsby enter a “paired exchange,” a way to find organ matches through a larger pool of people. In such an exchange, one person does not donate a kidney directly to the other person. Instead, two pairs of people trade donations to make two transplants possible. Hornsby’s cousin, Allison Feller, became her “pair partner.” They were matched four times with other pairs for transplants that did not pan out, for various reasons.
“I learned that … the whole process is a rollercoaster ride of emotions,” Hornsby said, “and it is most important to focus on getting the exact right kidney that was meant for me.”
Finally, Hornsby’s team found a good exchange pair for her and Feller: a couple in Ohio. Feller would donate a kidney to the Ohio man. His wife would donate her kidney to Hornsby, for whom she was a good match (the wife’s kidney was not a good match for her husband). Hornsby’s medical team set a transplant date of Aug. 27, 2015. Her kidney function was at 9 percent.
Suddenly, a choice of kidneys
Shortly before that transplant date, Hornsby got an unexpected call from one of her doctors, Beatrice Concepcion, M.D. A kidney was available from the national wait list that was a perfect match for Hornsby, despite her high antibodies.
“That night a family made a very difficult decision to give their loved one’s organs to save the lives of six people,” Hornsby said. “I ended up being one of the six, though it was an intensely hard decision.” It’s rare that someone must choose between two transplant options — a kidney from the wait list versus one from a live donor — and Hornsby, her husband and her team decided “the kidney waiting for me at the hospital was indeed the best one for me.”
Hornsby had her kidney transplant on Aug. 17, 2015.
Six months later, Hornsby and her doctors dealt with organ-rejection problems. It was frightening, but under transplant nephrologist Heidi Schaefer, M.D.’s, care, she recovered. By early 2017, Hornsby was healthy and back to volunteer work, including with Monroe Carell Jr. Children’s Hospital at Vanderbilt. She and her husband are raising their 18-year-old sons and 11-year-old daughter.
Though Hornsby no longer needed the donation that would have resulted from the paired exchange, her cousin went through with the kidney donation to the man in Ohio.
“She was invested in the process,” Hornsby said, “and just did not want to sit back in her life and know that someone out there needed a life-saving kidney that she could give.”
Later, the family learned that the Ohio man’s wife was so grateful that she went on to donate her kidney, the one that would have gone to Hornsby, to someone else.
