As we look forward to meeting up in person once again at our IPTA Congress year in 2023, let’s take a look back over what IPTA has achieved in 2022!

Here are some of the highlights:

  • IPTA 2022 Congress - our Virtual Congress was a huge success! The virtual format also allowed for IPTA members from all over the globe to easily participate. With a combined registration and membership package offered, we were able to grow membership exponentially, welcoming new members to IPTA from places such as Botswana, Bolivia, and Georgia. Recordings are available to IPTA members and can be viewed here:

Recently it has been all over the news that the first partial pediatric heart transplant was performed in the USA. This is a huge advancement for many reasons. There are many children born every year with unrepairable heart valve dysfunction (pulmonary atresia, truncus arteriosus, and aortic stenosis) and this is a huge problem because there are no growing heart valve implants outside of an entire heart transplant. There are mechanical valves for children, but most infants are too small for these. These mechanical valves also require lifelong anticoagulation which is not ideal in active children. Additionally, mechanical valves do not grow as the patient ages which necessitates reoperations as the child grows. There are also bioprosthetic valves (xenografts and homografts) but these too need to be replaced as the child grows and are not without other risks such as infection and calcifications. Heart transplantation is also an option, as the valves from a heart transplant do grow with the child and do not require replacement. But there is a lack of suitable donors for infants <1 year of age and the wait list mortality for this age group is high. This also requires life-long immunosuppression in a patient population with very naïve immune systems.

Researchers at Duke University and the Medical University of South Carolina have found an innovative solution. Partial heart transplantation is a new approach which involves transplantation of the heart valves only. Partial heart transplantation may offer the ability to use much lower immunosuppression as there is some immune privilege in this tissue. You might have heard of the concept of immune privilege in the past. This term was initially described by was coined by Sir Peter Medawar in the 1940s to describe parts of the body in which the introduction of foreign antigens does not elicit an inflammatory immune response. In fact, aortic homografts have been used since the early 1960s without the need for immunosuppression. There is some debate as to the actual immunogenicity of heart valves. Some studies have shown valves from transplanted hearts with severe rejection were spared 1, while others have shown the immunologic potential of these valves 2. Hill et al wrote a great review of the Immune Privilege of Heart Valves 3.

Partial heart transplantation can be performed using donor hearts with poor ventricular function and slow progression to donation after cardiac death that would normally be discarded making use of many more hearts. This amazing advancement could possibly ameliorate the need for donor hearts in children with unrepairable heart valve dysfunction and progression of these children to end-stage heart failure 4.

Dr. Tarak (Konrad) Rajab will be giving a plenary talk at IPTA’s 2023 Congress in Austin, Tx on his pivotal work on this advancement. This session will be on Monday, March 27th 14:45-15:15 CT. www.ipta2023.org/program/confirmed-speakers. Come join us to learn more!

Respectfully submitted by Pankaj Chandak, MD and Manuel Rodriguez-Davalos, MD - IPTA Membership Communication Committee Co-Chairs

The new IPTA Membership Communications Committee was formed earlier this year with members combined from both committees. The aim of the combined committee was to continue to provide enhanced visibility of the fantastic work of IPTA team members across appropriate social media networks to help drive membership interest, especially from LMIC, Latin America, Asia and Africa.

We have continued to use active Twitter and LinkedIn accounts (thanks to our social media expert Sarah Francom) and Nima Memaran (Hannover, Germany) has produced some fantastic videos of pediatric transplantation “pillars”. Srinath Chinnakotla has led the ListServ project which is up and running.

The Committee will continue to promote the inaugural IPTA Outreach Fellowship for LMIC and also to promote student membership and mentoring schemes.

We look forward to seeing you in Texas, Austin for IPTA 2023!

The Publications Committee have decided to contribute one article to the newsletter from journals other than Pediatric Transplantation that is deemed outstanding. Please see the rationale behind the selection of this quarter’s article below.

Survival Benefit of Donation After Circulatory Death Kidney Transplantation in Children Compared with Remaining on the Waiting List for a Kidney Donated After Brain Death

Sarah J. Kizilbash, MD, MS,1 Michael D. Evans, MS,2 and Blanche M. Chavers, M Transplantation 2022;106: 575–583

In 2018, in USA, one-fifth of adult deceased donor kidney transplants were transplants donated after circulatory death (DCD). Despite the increasing use in adults, only 2.5% of children in this cohort received a DCD transplant. We share this article because this is the first study to report a survival benefit of DCD transplantation in children compared to those remaining on the waitlist and no difference in long-term graft outcomes, specifically for kidneys with warm ischemia time <15 minutes. Although in this cohort DCD transplantation was associated with a higher incidence of delayed graft function compared to patients who received a kidney donated after brain death (DBD), (adjusted odds ratio: 3.0; p<0.001), the risks of graft failure (adjusted hazard ratio: 0.89; P=0.46) and death (adjusted hazard ratio 1.2; P=0.67) were similar between DCD and DBD recipients. Based on their findings the authors suggest that DCD kidneys should be considered for pediatric candidates who lack a living donor, particularly for those with high pretransplant morbidity and mortality.
