Good evening everyone,
I'm here to share another update, please bear with me while I try to organize all the things that have happened this weekend.
Last updated I had mentioned that her chest was scheduled to be closed. Well big shocker that didn't happen. The team was not comfortable attempting to close her chest with her numbers being high. They also did an echo that showed decreased function of the right ventricle. While an echo on an open chest in difficult in of itself, the decreased function had the team extremely worried. We were told they were worried about rejection in the heart and wanted to get her scheduled for Cath lab and biopsy asap.
Normally post-transplant kids will get a Cath lab with biopsy to check for rejections at 2 weeks. Due to everything weird going on with Annabelle the team decided to move the Cath lab up to Friday. We were told the results likely wouldn't be back till Monday but that they would start her on a high dose steroid and raise her immunosuppressants to help fight any rejection that could be happening.
The Cath lab went well, Annabelle remained stable and comfortable the whole time. Her pressures in the heart were more stable than the team expected and gave them the impression that we might not be dealing with sever rejection. There was more concern that the right ventricle was being compressed due to fluid/the chest wall along with some possible rejection. The Cath lab also showed that the left ventricle, left atrium, and right atrium all had great function. The team continued to treat as if there was rejection just to cover all bases and keep Annabelle safe, but we were relieved to know there could be another answer for why the right ventricle was struggling.
Side note, because I know the average person is not super well versed in all things pediatric transplant. Rejection can be treated. It can get worse, and it can be better. At any time in a transplant recipient’s life they can deal with rejection. Rejection is measured in stages, 0, 1R, 2R, and 3R. Obviously we would love to never deal with rejection but that likely isn't going to happen. Annabelle also is a bit of a complicated case due to her kidney failure. With a normal heart transplant patient, the team would use three immunosuppressants, Thymoglobulin, Tacrolimus, Cellcept. Due to her needing a kidney the team held the Thymoglobulin because that will be used with the kidney transplant. If they were to use Thymoglobulin, we would have to wait for up to six months to get a kidney transplant. They teams hope is that we can manage Annabelle's antibodies with only Tacrolimus and Cellcept until she receives her kidney.
Due to them holding the Thymo everyone has been extremely on top of all her levels, but I also believe that this is why everyone is so jumpy about the decreased function in the right ventricle. While we are so grateful to have everyone watching her closely it has caused increased stress for us. We knew that this transplant was only the beginning of a very different journey, but I don't believe we truly understood how traumatizing the first 6 months of Annabelle's life were to us. Seeing her paralyzed and intubated with alarms going off by the minute and at least 10 people in and out of our room is a lot. Simply put its a lot of everything all at once.
Over the weekend while we waited for the results to come back, we got word that the preliminary results of the biopsy that was done showed 1R rejection. We were told this wasn't the final results but either way they would keep her on steroids an extra 3 days and keep working on the immunosuppressants. This wasn't the news we wanted to hear especially since we know her crossmatch was negative, and she clinically has improved since transplant. I took some time to talk with her transplant doctor and he explained that this was very treatable, and he would tell me if we needed to worry. He was very open and positive that this level of rejection is manageable and could very likely be due to the fact she didn't receive Thymo after transplant and that she is on CRRT for dialysis.
While the news of the possible rejection hit hard, I was reminded that clinically Annabelle looked great and was improving daily in her levels, vent support, and fluid balance. I took all these as small wins and tried to let go of that fact that we still had a very long way to go before we would see her awake again.
This morning at rounds there was talk of trying to close her chest as long as her pressures allowed, and she tolerated it. Around 11am they were able to close part of her chest. She experienced a couple hours of lower blood pressures but with fluid and a little EPI she was able to level out and has been doing great. They also removed her paralytic, and she has been morning around a bit more. Still very sedated but it's been nice to see her twitch a hand or foot every once in a while.
The final results from the biopsy also came back confirming the 1R rejection. Hearing that news this afternoon did sting a little but after the talk with her doctor on Sunday I feel like we did everything possible to treat it. I also see that she is continuing to improve clinically so worrying about it helps nothing.
Our next big steps are to get her chest closed completely, get back to using our PD drain for dialysis, remove her breathing tube, and turn off all sedation. That is a LOT of big steps, and we will likely be working on them for a month or so but for now we are happy to take the small steps forward.
Please continue to pray for Annabelle and that she can keep getting stronger and healthier. We will update when more things happen.
Love,
Sidney & Luke
