Long-term outcome of deceased donor renal transplantation in pediatric recipients: a single-center experience from a developing country

Paediatric kidney transplantation in under-resourced regions-a panoramic view

Kidney transplantation is the ideal choice of kidney replacement therapy in children as it offers a low risk of mortality and a better quality of life. A wide variance in the access to kidney replacement therapies exists across the world with only 21% of low- and low-middle income countries (LLMIC) undertaking kidney transplantation. Pediatric kidney transplantation rates in these under-resourced regions are reported to be as low as < 4 pmcp [per million child population]. A robust kidney failure care program forms the cornerstone of a transplant program. Even the smallest transplant program entails a multidisciplinary workforce and expertise besides ensuring family commitment towards long-term care and economic burden. In general, the short-term graft survival rates from under-resourced regions are comparable to most high-income countries (HIC) and the challenge lies in the long-term outcomes. This review focuses on specific issues relevant to kidney transplants in children in under-resourced regions by highlighting limitations in the capacity and health workforce, regulatory norms, medical issues, economic burden, factors beyond financial hardship and ethical considerations relevant to these regions. Finally, the perspective of strengthening transplant programs in these regions should factor in the bigger challenges that exist in achieving the health-related sustainable development goals by 2030.

Two Decades of Deceased Donor Kidney Transplantation at Ahmedabad, India

OBJECTIVES

Gujarat, Tamil Nadu, Telangana, Maharashtra, Kerala, Chandigarh, and Karnataka are states in India with active programs for deceased donor kidney transplant. We report our experience of 2 decades of deceased donor kidney transplant at the Institute of Kidney Diseases and Research Center, Dr. H. L. Trivedi Institute of Transplantation Sciences, Ahmedabad, Gujarat, India.

MATERIALS AND METHODS

This single-center retrospective study comprised data from 831 deceased donor kidney transplant recipients between January 1, 1997 and December 31, 2018. Mean recipient age was 38 ± 14 years; 564 were male, and 267 were female. Mean donor age was 45.3 ± 17.13 years; 565 were men, and 266 were women.

RESULTS

Between January 1, 1997 and March 15, 2020, 5838 kidney transplants were completed, including 4895 living donor kidney transplants, 943 deceased donor kidney transplants, and 440 kidney paired donation transplants. Over the mean follow-up time of 8 ± 5.4 years, patient survival rate was 70% (n = 581) and death-censored graft survival rate was 84% (n = 698). Delayed graft function was shown in 210 patients (25%) and biopsy-proven acute rejection rate in 180 patients (21%). Our experience of favorable outcomes with deceased donor kidney transplants has expanded the donor pool in many ways, including transplant from expanded criteria donors to younger recipients; transplant from older donors to older recipients; donation after cardiac death; successful intercity organ procurement; dual-kidney transplant; en bloc transplant from a pediatric deceased donor; and transplant from brain death deceased donors who died from neurotoxic snakebite, recurrent primary brain tumor, bacterial meningitis, or head injury, or with disseminated intravascular coagulation and deranged renal functions. The pathway to increase organ donation was investigated.

CONCLUSIONS

Deceased donor kidney transplant can achieve acceptable graft function with patient/graft survival, which may encourage the use of this approach to increase the number of available organs.

Deceased-Donor Organ Transplantation in India: Current Status, Challenges, and Solutions

Tamil Nadu, Gujarat, Telangana, Maharashtra, Kerala, Chandigarh, Karnataka, National Capital Territory of Delhi, and Rajasthan are states and union territories having active deceased-donor organ transplant programs in India. Transplant data (2013-2018) have been collected by the National Organ and Tissue Transplant Organization from all states and union territories of India and submitted to the Global Observatory on Donation and Transplantation. From 2013 to 2018, 49155 transplants were reported in India, including 39000 living-donor organ recipients and 10 155 deceased-donor organ recipients. These transplants were for kidney (living donor = 32584, deceased donor = 5748), liver (living donor = 6416, deceased donor = 2967), heart (deceased donor = 895), lung (deceased donor = 459), pancreas (deceased donor = 78), and small bowel (deceased donor = 8). According to 2018 data, India was the second largest transplanting country in the world in terms of the absolute number of transplants. Here, we discuss the status, progress, challenges, and solutions for deceaseddonor organ transplantation. The plan to increase rates of organ donation in India include the following points: teamwork and focus by intensive care unit doctors; public education on organ donation using social media; professional education and family donation conversation programs for brain death declaration and donor management; organ procurement organizations; international collaboration and regular meetings and updates for organizations working in the field of organ transplantation; grief counseling and reporting of potential donation for families of recently deceased people; nonfinancial incentivization to families of potential organ donors; expert committees and standard operating protocols for use of marginal donor organs, donation after circulatory death programs, and machine perfusion; maintenance of transparency and ethics in organ donation, allocation, and transplantation as directed by governmental, nongovernmental, and intergovernmental entities; and regular audit of progress and registry data.

Pediatric renal transplant practices in India

Limited access to tertiary-level health care, limited trained pediatric nephrologists and transplant physicians, lack of facilities for dialysis, lack of an effective deceased donor program, non-affordability, and non-adherence to immunosuppressant drugs poses a major challenge to universal availability of pediatric transplantation in developing countries. We present the results of a survey which, to the best of our knowledge, is the first such published attempt at understanding the current state of pediatric renal transplantation in India. A designed questionnaire formulated by a group of pediatric nephrologists with the aim of understanding the current practice of pediatric renal transplantation was circulated to all adult and pediatric nephrologists of the country. Of 26 adult nephrologists who responded, 16 (61.5%) were involved in pediatric transplantation, and 10 of 15 (66.6%) pediatric nephrologists were involved in pediatric transplantation. Most of the centers doing transplants were private/trust institution with only three government institutions undertaking it. Induction therapy was varied among pediatric and adult nephrologists. There were only a few centers (n=5) in the country routinely doing >5 transplants per year. Preemptive transplants and protocol biopsies were a rarity. The results demonstrate lower incidence of undertaking pediatric transplants in children below 6 years, paucity of active cadaveric programs and lack of availability of trained pediatric nephrologists and staff. In contrast to these dissimilarities, the immunosuppressant use seems to be quite similar to Western registry data with majority favoring induction agent and triple immunosuppressant (steroid, mycophenolate mofetil and tacrolimus) for maintenance. The survey also identifies major concerns in availability of this service to all regions of India as well as to all economic segments.

Outcome of renal transplantation from deceased donors: experience from developing country

BACKGROUND

In India, there are a large number of end-stage renal disease (ESRD) patients waiting for renal transplantation (RT). Organ retrieval from brain dead deceased donor (DD) is getting increased attention as the waiting list for organ recipients far exceeds the organ donor pool. In our country, despite a large population, the number of brain dead donors undergoing organ donation is very less. DDRT is the possible solution to bridge the disparity between organ supply and demand. In India, the potential for DDRT is huge due to the high number of fatal road traffic accidents and this pool is yet to be tapped.

PATIENTS AND METHODS

We report DDRT outcome in 294 patients (age: 36.5 ± 14.1 years; male:female, 200:94) between 2005 and 2012. All patients received single-dose rabbit-anti-thymocyte globulin for induction and steroids, calcineurin inhibitor, and mycophenolate mofetil/azathioprine for maintenance immunosuppression.

RESULTS

Our retrospective study in 294 DDRT shows a fairly successful outcome. Over a mean follow-up of 3.93 years, patient and graft survival rates were 81.7% and 92.6%, respectively, with a median serum creatinine of 1.5 mg/dL. 20.7% had biopsy-proven acute rejection.

CONCLUSION

Given the widespread organ shortage, DDRT has a potential to expand the donor pool and shorten the waiting list for RT, encouraging the use of this approach even in low-income countries. Aggressive donor management, increasing public awareness about the concept of organ donation, good communication between clinician and the family members, and a well-trained team of transplant coordinators can help in improving the number of organ donations.
