ABSTRACT

SARS-CoV-2 (corona virus) presents the world with new kinds of challenges. The crisis mode that persisted in many countries also put a strain on the German health system: on the one hand, through the treatment of patients infected with corona, and on the other hand through the cancellation and postponement of elective operations. This had a corresponding impact on tissue donation and transplantation. The effects of the pandemic-related restrictions can be reflected by the rate of corneal donation in the DGFG network: With the beginning of the first closure in Germany, donation and transplant numbers decreased by almost 25% from March to April 2020. After a recovery during summer, the activities were again restricted from October onwards due to increasing infection numbers. Subsequently in 2021 there was a similar trend.The already careful screening of potential tissue donors was expanded in accordance with the guidelines of the Paul-Ehrlich-Institute. However, this important measure led to an increase in discontinued donations due to medical contraindications from 44% in 2019 to 52% in 2020 and 55% in 2021 (Status Nov 2021). Nevertheless, the donation and transplantation result from 2019 was exceeded and DGFG was able to maintain patient care in Germany on stable level compared to other European countries. This positive result is partly due to an increased consent rate of 41% in 2020 and 42% in 2021 due to a higher sensitivity in the population to health issues during the pandemic. In 2021, the situation stabilised again, although the number of donations that could not be realised due to corona detection in the deceased continued to increase with the waves of infections that occurred.Low losses in donation and thus in the supply of transplants for patients seem to be due to the fact that a nationwide network such as the DGFG can respond flexibly to changing requirements. For example, if the number of COVID-19 infections varies between regions, it is possible to react to the local conditions to continue donation and processing where possible and allow allocation to regions where transplantation can take place.In summary it has been shown that efficient donation programs, resilient network structures, awareness of population for tissue donation and effective precautionary measures ensure a safe patient care with corneal transplants also in pandemic times.

ABSTRACT

PURPOSE OF REVIEW: The deceased donor organ pool has broadened beyond young, otherwise healthy head trauma victims. But an abundance of donated organs only benefits patients if they are accepted, expeditiously transported and actually transplanted. This review focuses on postdonation challenges and opportunities to increase the number of transplants through improved organ utilization. RECENT FINDINGS: We build upon recently proposed changes in terminology for measuring organ utilization. Among organs recovered for transplant, the nonuse rate (NUR REC ) has risen above 25% for kidneys and pancreata. Among donors, the nonuse rate (NUR DON ) has risen to 40% for livers and exceeds 70% for thoracic organs. Programme-level variation in offer acceptance rates vastly exceeds variation in the traditional, 1-year survival benchmark. Key opportunities to boost utilization include donation after circulatory death and hepatitis C virus (HCV)+ organs; acute kidney injury and suboptimal biopsy kidneys; older and steatotic livers. SUMMARY: Underutilization of less-than-ideal, yet transplant-worthy organs remains an obstacle to maximizing the impact of the U.S. transplant system. The increased risk of inferior posttransplant outcomes must always be weighed against the risks of remaining on the waitlist. Advanced perfusion technologies; tuning allocation systems for placement efficiency; and data-driven clinical decision support have the potential to increase utilization of medically complex organs.

ABSTRACT

BACKGROUND: There is a paucity of data on heart transplantation (HT) using COVID-19 donors. OBJECTIVES: This study investigated COVID-19 donor use, donor and recipient characteristics, and early post-HT outcomes. METHODS: Between May 2020 and June 2022, study investigators identified 27,862 donors in the United Network for Organ Sharing, with 60,699 COVID-19 nucleic acid amplification testing (NAT) performed before procurement and with available organ disposition. Donors were considered "COVID-19 donors" if they were NAT positive at any time during terminal hospitalization. These donors were subclassified as "active COVID-19" (aCOV) donors if they were NAT positive within 2 days of organ procurement, or "recently resolved COVID-19" (rrCOV) donors if they were NAT positive initially but became NAT negative before procurement. Donors with NAT-positive status >2 days before procurement were considered aCOV unless there was evidence of a subsequent NAT-negative result ≥48 hours after the last NAT-positive result. HT outcomes were compared. RESULTS: During the study period, 1,445 "COVID-19 donors" (COVID-19 NAT positive) were identified; 1,017 of these were aCOV, and 428 were rrCOV. Overall, 309 HTs used COVID-19 donors, and 239 adult HTs from COVID-19 donors (150 aCOV, 89 rrCOV) met study criteria. Compared with non-COV, COVID-19 donors used for adult HT were younger and mostly male (∼80%). Compared with HTs from non-COV donors, recipients of HTs from aCOV donors had increased mortality at 6 months (Cox HR: 1.74; 95% CI: 1.02-2.96; P = 0.043) and 1 year (Cox HR: 1.98; 95% CI: 1.22-3.22; P = 0.006). Recipients of HTs from rrCOV and non-COV donors had similar 6-month and 1-year mortality. Results were similar in propensity-matched cohorts. CONCLUSIONS: In this early analysis, although HTs from aCOV donors had increased mortality at 6 months and 1 year, HTs from rrCOV donors had survival similar to that seen in recipients of HTs from non-COV donors. Continued evaluation and a more nuanced approach to this donor pool are needed.

ABSTRACT

The past 5 years have posed challenges to the field of heart transplantation. The 2018 heart allocation policy revision was accompanied by anticipated practice adjustments and increased use of short-term circulatory support, changes that may ultimately serve to advance the field. The COVID-19 pandemic also had an impact on heart transplantation. While the number of heart transplants in the United States continued to increase, the number of new candidates decreased slightly during the pandemic. There were slightly more deaths following removal from the waiting list for reasons other than transplant during 2020, and a decline in transplants among candidates listed as status 1, 2, or 3 compared with the other statuses. Heart transplant rates decreased among pediatric candidates, most notably among those younger than 1 year. Despite this, pretransplant mortality has declined for both pediatric and adult candidates, particularly candidates younger than 1 year. Transplant rates have increased in adults. The prevalence of ventricular assist device use has increased among pediatric heart transplant recipients, while the prevalence of short-term mechanical circulatory support, particularly intra-aortic balloon pump and extracorporeal membrane oxygenation, has increased among adult recipients.

ABSTRACT

The number of lung transplants has continued to decline since 2020, a period that coincides with the onset of the COVID-19 pandemic. Lung allocation policy continues to undergo considerable change in preparation for adoption of the Composite Allocation Score system in 2023, beginning with multiple adaptations to the calculation of the Lung Allocation Score that occurred in 2021. The number of candidates added to the waiting list increased after a decline in 2020, while waitlist mortality has increased slightly with a decreased number of transplants. Time to transplant continues to improve, with 38.0% of candidates waiting fewer than 90 days for a transplant. Posttransplant survival remains stable, with 85.3% of transplant recipients surviving to 1 year; 67%, to 3 years; and 54.3%, to 5 years.

ABSTRACT

The OPTN/SRTR 2021 Annual Data Report presents the status of the solid organ transplantation system in the United States from 2010 through 2021. Organ-specific chapters are presented for kidney, pancreas, liver, intestine, heart, and lung transplant. Each organ-specific chapter is organized to present waitlist information, donor information (both deceased and living, as appropriate), transplant information, and patient outcomes. Data pertaining to pediatric patients are generally presented separately from the adult data. In addition to the organ-specific chapters, you will find chapters dedicated to deceased organ donation, vascularized composite allograft, and the COVID-19 pandemic. The data presented in the Annual Data Report are descriptive in nature. In other words, most tables and figures present raw data without statistical adjustment for possible confounding or changes over time. Therefore, the reader should keep in mind the observational nature of the data when attempting to draw inferences before trying to ascribe a cause to any observed patterns or trends. This introduction provides a brief overview of trends in waitlist and transplant activity. More detailed descriptions can be found in the respective organ-specific chapters.

ABSTRACT

This chapter updates the COVID-19 chapter from the 2020 Annual Data Report with trends through February 12, 2022, and introduces trends in COVID-19-specific cause of death on the waiting list and posttransplant. Transplant rates remain at or above prepandemic levels for all organs, indicating a sustained transplantation system recovery following the initial 3-month disruption due to the onset of the pandemic. Posttransplant mortality and graft failure remain a concern in all organs, with rates surging corresponding to waves of the pandemic. Waitlist mortality due to COVID-19 is also a concern, particularly among kidney candidates. While the recovery of the transplantation system has been sustained in the second year of the pandemic, ongoing efforts should focus on reducing posttransplant and waitlist mortality due to COVID-19, and graft failure.

ABSTRACT

The year 2021 marked both successes and challenges for the field of kidney transplantation, in the context of the ongoing COVID-19 pandemic and broader geographic organ distribution. The total number of kidney transplants in the United States reached a record count of 25,487, driven by growth in deceased donor kidney transplants. The total number of candidates listed for deceased donor kidney transplant rose slightly in 2021 but remained below 2019 listing levels, with nearly 10% of candidates having been waiting 5 years or longer. Pretransplant mortality declined slightly among candidates of Black, Hispanic, and other races, in parallel with increasing numbers of Black and Hispanic transplant recipients. In the context of broader organ sharing, there is growing disparity in pretransplant mortality among non-metropolitan compared with metropolitan residents. The proportion of deceased donor kidneys recovered but not used for transplant (nonuse rate) rose to a high of 24.6% overall, with greater nonuse among biopsied kidneys (35.9%), kidneys from donors aged 55 years or older (51.1%), and kidneys with kidney donor profile index (KDPI) of 85% or greater (66.6%). Nonuse of kidneys from donors who are hepatitis C virus (HCV) antibody positive only slightly exceeded that of HCV antibody-negative donors. Disparities in access to living donor kidney transplant persists, especially for non-White and publicly insured patients. Delayed graft function continues an upward trend and occurred in 24% of adult kidney transplants in 2021. Five-year graft survival after living compared with deceased donor transplant was 88.6% versus 80.7% for recipients aged 18-34 years, and 82.1% versus 68.0% for recipients aged 65 years or older. The total number of pediatric kidney transplants performed increased to 820 in 2021, the highest number since 2010. Despite numerous efforts, living donor kidney transplant remains low among pediatric recipients, with continued racial disparities. The rate of deceased donor transplants among pediatric candidates recovered in 2021 from a low in 2020. Congenital anomalies of the kidney and urinary tract remain the leading primary kidney disease diagnosis among pediatric candidates. Most pediatric deceased donor recipients receive a kidney from a donor with KDPI less than 35%. Graft survival continues to improve, with superior outcomes for living donor transplant recipients.

ABSTRACT

In 2021, liver transplant volume continued to grow, with a record 9,234 transplants performed in the United States, 8,665 (93.8%) from deceased donors and 569 (6.2%) from living donors. There were 8,733 (94.6%) adult and 501 (5.4%) pediatric liver transplant recipients. An increase in the number of deceased donor livers corresponded to an increase in the overall transplant rate and shorter waiting times, although still 10.0% of livers that were recovered were not transplanted. Alcohol-associated liver disease was the leading indication for both waitlist registration and liver transplant in adults, outpacing nonalcoholic steatohepatitis, while biliary atresia remained the leading indication for children. Related to allocation policy changes implemented in 2019, the proportion of liver transplants performed for hepatocellular carcinoma has decreased. Among adult candidates listed for liver transplant in 2020, 37.7% received a deceased donor liver transplant within 3 months, 43.8% within 6 months, and 53.3% within 1 year. Pretransplant mortality improved for children following implementation of acuity circle-based distribution. Short-term graft and patient survival outcomes up to 1 year worsened for adult deceased and living donor liver transplant recipients, which is a reversal of previous trends and coincided with the onset of the COVID-19 pandemic in early 2020. Longer-term outcomes among adult deceased donor liver transplant recipients were unaffected, with overall posttransplant mortality rates of 13.3% at 3 years, 18.6% at 5 years, and 35.9% at 10 years. Pretransplant mortality improved for children following implementation of acuity circle-based distribution and prioritization of pediatric donors to pediatric recipients in 2020. Pediatric living donor recipients had superior graft and patient survival outcomes compared with deceased donor recipients at all time points.

ABSTRACT

The number of pancreas transplants in the United States was largely unchanged in 2021 at 963 transplants compared with 962 in 2020, showing that recovery from the COVID-19 pandemic was not as pronounced in pancreas transplantation as in other organs. The number of simultaneous pancreas-kidney transplants (SPKs) decreased from 827 to 820, whereas the number of pancreas-after-kidney transplants and pancreas transplants alone increased marginally to compensate. The proportion of patients with type 2 diabetes on the waiting list increased to 22.9% in 2021, compared with 20.1% in 2020. Consequently, the proportion of transplants in patients with type 2 diabetes increased from 21.3% in 2020 to 25.9% in 2021. The proportion of transplants in older recipients (aged 55 years or older) also increased to 13.5% in 2021 from 11.7% in 2020. Outcomes after SPK continue to be the best of the three categories of pancreas transplants: 1-year graft failure for kidney at 5.7% and pancreas at 10.5% for transplants performed in 2020. The proportion of pancreas transplants performed by medium-volume centers (11-24 transplants per year) increased sharply to 48.3% in 2021 from 35.1% in 2020, with a corresponding decrease in transplants in large-volume centers (25 or more transplants per year) to 15.9% in 2021 from 25.7% in 2020.

ABSTRACT

The Scientific Registry of Transplant Recipients uses data collected by the Organ Procurement and Transplantation Network to calculate metrics such as donation rate, organ yield, and rate of organs recovered for transplant but not transplanted (ie, nonuse). In 2021, there were 13,862 deceased donors, a 10.1% increase from 12,588 in 2020, and an increase from 11,870 in 2019; this number has been increasing since 2010. The number of deceased donor transplants increased to 41,346 transplants in 2021, a 5.9% increase from 39,028 in 2020; this number has been increasing since 2012. The increase may be due in part to the rising number of deaths of young people amid the ongoing opioid epidemic. The number of organs transplanted included 9,702 left kidneys, 9,509 right kidneys, 551 en bloc kidneys, 964 pancreata, 8,595 livers, 96 intestines, 3,861 hearts, and 2,443 lungs. Compared with 2019, transplants of all organs except lungs increased in 2021, which is remarkable as this occurred despite the COVID-19 pandemic. In 2021, 2,951 left kidneys, 3,149 right kidneys, 184 en bloc kidneys, 343 pancreata, 945 liver, 1 intestine, 39 hearts, and 188 lungs were not used. These numbers suggest an opportunity to increase numbers of transplants by reducing nonused organs. Despite the pandemic, there was no dramatic increase in number of nonused organs and there was an increase in total numbers of donors and transplants. The new Centers for Medicare & Medicaid Services metrics for donation rate and transplant rate have also been described and vary across organ procurement organizations; the donation rate metric varied from 5.82 to 19.14 and the transplant rate metric varied from 18.7 to 60.0.

ABSTRACT

Despite the fact that the last year has been marked by the SARS-CoV-2 pandemic, there have been many articles published on non-COVID pneumonia. Making the selection has not been easy, having based on those articles that we think can bring us some novelty and help in clinical practice. We have divided the selection into seven sections: patient severity, diagnosis, treatment, ventilation, novelties in the guidelines, fungal infection and organ donation.

ABSTRACT

Organ transplant is one of the best options for many medical conditions, and in many cases, it may be the only treatment option. Recent evidence suggests, however, that the COVID-19 pandemic might have detrimentally affected the provision of this type of healthcare services. The main purpose of this article is to use Data Envelopment Analysis and the Malmquist Index to assess the impact that the pandemic caused by the novel coronavirus SARS-CoV-2 had on the provision of solid organ transplant services. To this purpose, we use three complementary models, each focusing on specific aspects of the organ donation and transplantation process, and data from Brazil, which has one of the most extensive public organ transplant programs in the world. Using data from 17 States plus the Federal District, the results of our analysis show a significant drop in the performance of the services in terms of the organ donation and transplantation process from 2018 to 2020, but the results also indicate that not all aspects of the process and States were equally affected. Furthermore, by using different models, this research also allows us to gain a more comprehensive and informative assessment of the performance of the States in delivering this type of service and identify opportunities for reciprocal learning, expanding our knowledge on this important issue and offering opportunities for further research.

ABSTRACT

Introducción. La pandemia por COVID-19 ha causado la muerte de 6,5 millones de personas en el mundo y la donación de órganos se ha visto ampliamente afectada, reflejándose en una disminución importante en el número de trasplantes. Colombia no ha sido ajena a dicha problemática. Ante este desafío, el Instituto Nacional de Salud ha permitido tomar donantes cadavéricos con reacción en cadena de la polimerasa con transcripción reversa (RT-PCR) positiva para Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), sin enfermedad activa. El objetivo de este estudio fue describir una serie de pacientes trasplantados de riñón con donantes cadavéricos con RT-PCR SARS-CoV-2 positivo y sus principales desenlaces clínicos. Métodos. Serie de casos de pacientes que fueron llevados a trasplante renal con donante cadavérico con SARS-CoV-2 positivo, sin enfermedad activa, entre mayo y agosto de 2022. Se recolectaron las variables demográficas y clínicas y se evaluó la infección y la mortalidad asociada a SARS-CoV-2 en un mes de seguimiento. Resultados. Un total de 5 receptores de trasplante renal con 5 donantes cadavéricos SARS-CoV-2 positivos fueron evaluados. No se presentó mortalidad ni pérdida del injerto renal. Se registraron dos casos de función retardada del injerto y un caso de rechazo agudo. Ninguno de los pacientes presentó RT-PCR SARS-CoV-2 positiva en el seguimiento posterior al trasplante. Conclusión. Con nuestra serie de casos mostramos que el trasplante de riñón proveniente de donante cadavérico con prueba positiva para RT-PCR SARS-CoV-2, sin evidencia de enfermedad COVID-19 activa, es un procedimiento seguro y una estrategia eficaz para aumentar el número de donantes en pandemia


Introduction. Coronavirus Disease-2019 (COVID-19) pandemic have caused the death of 6.5 million of people worldwide. The organ donation was extremely affected reflecting in the number of transplants. Colombia has not been immune to this problem. Facing this challenge, the National Institute of Health (Instituto Nacional de Salud, INS) allowed to assign cadaveric donors with reverse transcription-polymerase chain reaction (RT-PCR) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive without COVID-19. We aim to describe a case series of kidney transplant patients with RT-PCR SARS-CoV-2 positive cadaveric donors, and their main clinical outcomes. Methods. A case series of five patients who underwent kidney transplantation of cadaveric donors with positive RT-PCR SARS-CoV-2 during the study period from May to august of 2022. Demographics and clinical characteristics were collected from the institutional medical records, and we evaluated the mortality and infection associated with SARS-CoV-2. Results. A total of five kidney transplant recipients and five cadaveric donors with positive RT-PCR SARS-CoV-2 were described in the present study. There were not mortality reported and none of the patients had graft loss. Two cases of delayed graft function and one case of acute kidney rejection were documented. None of the patients had positive RT-PCR SARS-CoV-2 in the follow-up. Conclusion. Our series demonstrated that the kidney transplant of cadaveric donors with positive RT-PCR SARS-CoV-2 without clinical evidence of active COVID-19 disease is a safe procedure and an efficient strategy to increase donors during a pandemic

ABSTRACT

Coronavirus disease 2019 (COVID-19) is caused by a highly contagious RNA virus termed as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Ophthalmologists are at high-risk due to their proximity and short working distance at the time of slit-lamp examination. Eye care professionals can be caught unaware because conjunctivitis may be one of the first signs of COVID-19 at presentation, even precluding the emergence of additional symptoms such as dry cough and anosmia. Breath and eye shields as well as N95 masks, should be worn while examining patients with fever, breathlessness, or any history of international travel or travel from any hotspot besides maintaining hand hygiene. All elective surgeries need to be deferred. Adults or children with sudden-onset painful or painless visual loss, or sudden-onset squint, or sudden-onset floaters or severe lid oedema need a referral for urgent care. Patients should be told to discontinue contact lens wear if they have any symptoms of COVID-19. Cornea retrieval should be avoided in confirmed cases and suspects, and long-term preservation medium for storage of corneas should be encouraged. Retinal screening is unnecessary for coronavirus patients taking chloroquine or hydroxychloroquine as the probability of toxic damage to the retina is less due to short-duration of drug therapy. Tele-ophthalmology and artificial intelligence should be preferred for increasing doctor-patient interaction.

ABSTRACT

Rates of lung donation have increased over the past several years. This has been accomplished through the utilization of donors with extended criteria, the creation of donor hospitals or centers, and the optimization of lungs through the implementation of donor management protocols. These measures have resulted in augmenting the pool of available donors thereby decreasing the wait time for lung transplantation candidates. Although transplant programs vary significantly in their acceptance rates of these organs, studies have not shown any difference in the incidence of primary graft dysfunction or overall mortality for the recipient when higher match-run sequence organs are accepted. Yet, the level of comfort in accepting these donors varies among transplant programs. This deviation in practice results in these organs going to lower-priority candidates thereby increasing the waitlist time of other recipients and ultimately has a deleterious effect on an institution's waitlist mortality.

ABSTRACT

BACKGROUND: COVID-19 is an important pandemic that affects the whole world. Another branch of the wreckage its devastating effects on the health care system is organ and cadaver donations. This article aimed to raise awareness about cadaver and organ donation during the COVID-19 period, with the support of student opinions. METHODS: Twelve opinions about cadaver and organ donation during the COVID-19 pandemic were presented to the fourth-, fifth-, and sixth-year students at the Kafkas University Faculty of Medicine. The answers were compared between male and female students using the χ2 test. RESULTS: It is seen that the data obtained about cadaver and organ donation are important. In addition, the storage conditions of cadavers and organs, the risk of disease transmission, and the risk of contamination are discussed with striking data. CONCLUSIONS: It is understood from the obtained data that awareness about cadaver and organ donation is always on the agenda. In particular, conferences and meetings should be held frequently to keep medicine faculty students informed. The handling of COVID-19 has also given a significant impetus to the research throughout.

ABSTRACT

End-stage kidney disease is a significant burden on the healthcare systems of many countries, and this is likely to continue because of an increasingly aging and comorbid population. Multiple studies have demonstrated a significant clinical benefit in transplantation when compared with dialysis, however, there continues to be a shortage of donor kidneys available. This article provides an economic perspective on issues pertinent to living kidney donation and transplantation. Although ethics, equity, and cultural considerations often seem at odds with economic concepts around resource allocation, this article explains the situation around supply and demand for living kidneys and illustrates how this has been addressed in the economic literature. The article discusses different policy recommendations for resolving the imbalance between supply and demand in kidney donation, through policies under 3 main approaches: increasing supply, decreasing demand, and improving the allocation of kidney supply.

ABSTRACT

INTRODUCTION: The incidence of organ transplantation between the Eastern and Western part of Europe is quite different. This has several reasons; the main cause may be the Great Schism (A. D. 1054) when the Byzantine Empire separated himself also religiously from Rome. Since then there has been a different historical development followable until our days. Later on, disintegration of four previous large empires into many smaller countries during the last 150 years, furthermore in the second half of the twentieth century the separation by the Iron Curtain in the middle of Europe led to different social-economic and infrastructural developments between the different parts of the continent. In the new millennium, all transplantations for the routinely performed 5 organs were available for the Hungarian patients, but the real era-changing happened in 2012/13 by joining Eurotransplant. OBJECTIVE: Our analysis is based on the transplantation numbers of the last pre-COVID pandemic year (2019). RESULTS: The abovementioned differences can be traced well by the transplantation numbers: 28 Western- and Middle-European countries have 22.2 cadaveric donors per million population versus 3.8 for 10 Eastern-European countries and another 7 do not have any. The numbers of transplanted organs are the following: 39.5 vs. 12.0 for kidney; 14.8 vs. 5.5 for liver; 5.4 vs. 0.8 for heart; 4.6 vs. 0.2 for lung. DISCUSSION: The statistics have also a rejoicing message because since the fall of the Iron Curtain, 10 Middle-European countries could reach the Western standards in organ transplantation. Their example is also good news for other Eastern European countries. CONCLUSION: Hungary was one of these countries who could benefit from the political changes and, by joining Eurotransplant, the quantity and quality of the transplanted organs was raised significantly: since then, there are by 40% more transplantations performed in our country.
