Diagnosis and treatment strategies for solid organ transplant recipients with SARS-CoV-2 infection / 器官移植

Due to long-term use of immunosuppressive agents, solid organ transplant recipients (SOTR) belong to high-risk populations of multiple pathogenic infection, including SARS-CoV-2. In addition, SOTR are constantly complicated by chronic diseases, such as hypertension and diabetes mellitus, etc. After infected with SARS-CoV-2, the critically ill rate and fatality of SOTR are higher than those of the general population, which captivates widespread attention from experts in the field of organ transplantation. Omicrone variant is currently the significant pandemic strain worldwide, rapidly spreading to more than 100 countries worldwide and causing broad concern. According to the latest international guidelines on the diagnosis and treatment of SARS-CoV-2 infection and relevant expert consensus in China combined with current domestic situation of SARS-CoV-2 pandemic and China's "diagnosis and treatment regimen for SARS-CoV-2 infection (Trial Version 10)", the epidemiology, clinical manifestations and prognosis, diagnosis, clinical classification and treatment of SARS-CoV-2 infection were briefly reviewed.

Preventive strategies for COVID-19 in solid organ transplantation recipients / 中华器官移植杂志

Since an outbreak of coronavirus disease 2019, there have been more than 664 million confirmed cases and more than 6.7 million deaths worldwide.The Omicron variant discovered in November 2021 has become a dominant variant in China.Compared with the general population, Omicron infection mainly presents short-term upper respiratory symptoms followed by quick recovery; solid organ transplant recipients have the characteristics of a high incidence of severe disease and high mortality after infection, and the incidence of secondary infection and rebound positivity is significantly higher than that of the general population.This review focused upon preventive strategies of solid organ transplant recipients from the perspectives of the characteristics of organ transplant recipients, general preventive strategies, vaccination and long-acting neutralizing antibodies.

Effect of body mass index of recipients on early prognosis after lung transplantation / 器官移植

Objective To evaluate the effect of body mass index (BMI) on early prognosis of the recipients after lung transplantation. Methods Clinical data of 307 lung transplant recipients were retrospectively analyzed. According to preoperative BMI, all recipients were divided into the low (BMI <18.5 kg/m2, n=114), normal (18.5 kg/m2≤BMI <24 kg/m2, n=145) and high (BMI≥24.0 kg/m2, n=48) BMI groups, respectively. Baseline data including age, sex, blood type, BMI, preoperative complications, preoperative pulmonary hypertension, and intraoperative use of extracorporeal membrane oxygenation (ECMO) of all recipients were compared among three groups. The survival rate of all recipients was estimated by Kaplan-Meier curve and the survival curve was delineated. The differences of survival rate were analyzed by log-rank test. The 30-, 90- and 180-d mortality risk of all recipients after lung transplantation in different BMI groups was compared by multivariate Cox regression analysis. Results There were significant differences in age and sex of recipients among three groups (both P<0.05). There was a significant difference regarding the 180-d survival rate after lung transplantation among different BMI groups (P<0.05). Multivariate Cox regression analysis showed that the 90-d mortality risk after lung transplantation in the high BMI group was 2.295 times higher than that in the normal BMI group [hazard ratio (HR) 2.295, 95% confidence interval (CI) 1.064-4.947, P=0.034]. In the high BMI group, the 180-d mortality risk after lung transplantation was 2.783 times higher compared with that in the normal BMI group (HR 2.783, 95%CI 1.333-5.810, P=0.006), and the 180-d mortality risk in the low BMI group was 2.181 times higher than that in the normal BMI group (HR 2.181, 95%CI 1.124-4.232, P=0.021). Conclusions Compared with the recipients with normal BMI, their counterparts with high and low preoperative BMI have higher mortality risk early after lung transplantation. Adjusting preoperative BMI to normal range contributes to improving early prognosis of lung transplant recipients.

Expert consensus on RhD blood group testing strategies in blood transfusion compatibility testing laboratories / 中国输血杂志

RhD antigen is the most immunogenic antigens in the Rh blood group system and can cause hemolytic transfusion reactions (HTRs) and severe hemolytic disease of the fetus and newborn (HDFN). RhD-negative red blood cell (RBC) is a scarce resource in China, and RhD-negative patients face challenges in timely blood transfusion. For different populations that were initially negative for RhD (saline method), what techniques should be used, how to issue test report and when should " Asian type" DEL (RHD*01EL.01, c.1227G>A) be identified are the confusions of blood transfusion workers in the process of clinical blood supply. More than 200 technical experts discussed and reached a consensus on blood transfusion compatibility testing for Chinese population. The purpose of the consensus is to further standardize and refine the RhD blood group testing strategy, provide technical support for achieving accurate blood transfusion for patients with different RhD blood groups, continuously improve the levels of prevention and treatment for RhD-HTRs and RhD-HDFN, and lay a foundation for the future development of industry standards concerning RhD blood group testing strategy.

Heterogeneity of psychological and behavioral adaptation characteristics of pediatric recipients after liver transplantation based on latent profile analysis / 器官移植

Objective To explore heterogeneous subtypes of psychological and behavioral adaptation characteristics of pediatric recipients after liver transplantation and the characteristics differences of different types of children after liver transplantation. Methods Seven hundred and forty-one children who underwent living-related liver transplantation were enrolled. The self-designed general information questionnaire, Chinese version of 5-Item World Health Organization Well-Being Index (WHO-5) and the parent-report version of the Strengths and Difficulties Questionnaire (SDQ) were filled out by their guardians. The scores of five dimensions of SDQ were used as the manifest variables of the model. The classification model of psychological and behavioral adaptation characteristics of pediatric recipients after liver transplantation was constructed by latent profile analysis. The latent categories of psychological and behavioral adaptation characteristics of pediatric recipients after liver transplantation were analyzed. The influencing factors of latent categories were analyzed by univariate analysis and logistic regression model. Results There were three latent categories of psychological and behavioral adaptation characteristics of pediatric recipients after liver transplantation, including peer communication problem group (n=302), psychological and behavioral adaptation group (n=145) and psychological and behavioral adjustment difficulty group (n=294). The first two groups were merged into the psychological and behavioral health group (n=447), which had significant differences in the five dimensions and the total score of difficulties of SDQ compared with the psychological and behavioral adjustment difficulty group (n=294) (all P<0.001). Logistic regression analysis showed that age≤5 years old, primary disease of non-cholestatic liver disease, stem family were the risk factors for psychological and behavioral adjustment difficulties in pediatric recipients after liver transplantation. Female gender, high education levels of parents and high WHO-5 score of guardians were the protective factors for psychological and behavioral adjustment difficulties in pediatric recipients after liver transplantation (all P<0.05). Conclusions The psychological and behavioral adaptation characteristics of pediatric recipients after liver transplantation are heterogeneous. Medical staff should pay extensive attention to different characteristics of pediatric recipients after liver transplantation with different psychological and behavioral adaptation categories and adopt targeted screening and intervention strategies, aiming to improve psychological and behavioral adaptation outcomes of pediatric recipients after liver transplantation.

Post-transplant idiopathic non-lupus full-house nephropathy – A case report

We report a case of Idiopathic non-lupus full-house nephropathy (NLFHN) in a 39-year-old male who had a full-house pattern of immunofluorescence study without overt systemic lupus erythematosus after a follow-up of more than 2 years. The incidence of detection of cases of NLFHN is increasing in native kidney biopsy and is critical to report as they have poor clinical outcomes. To the best of our knowledge, it is the first case of post-transplant renal biopsy and needs to be reported to plan the treatment protocol for such transplant patients.

Liver transplant after SARS-CoV-2 infection: A systematic review

Abstract Background: The Coronavirus 19 (COVID-19) pandemic has dramatically impacted liver organ transplantation. The American Society of Transplantation recommends a minimum of 28 days after symptom resolution for organ donation. However, the exact time for transplantation for recipients is unknown. Considering that mortality on the waiting list for patients with MELD >25 or fulminant hepatitis is higher than that of COVID-19, the best time for surgery after SARS-CoV-2 infection remains undetermined. This study aims to expand the current knowledge regarding the Liver Transplantation (LT) time for patients after COVID-19 and to provide transplant physicians with essential decision-making tools to manage these critically ill patients during the pandemic. Methods: Systematic review of patients who underwent liver transplantation after diagnosis of COVID-19. The MEDLINE, PubMed, Cochrane, Lilacs, Embase, and Scielo databases were searched until June 20, 2021. The MESH terms used were "COVID-19" and "Liver transplantation". Results: 558 articles were found; of these 13 articles and a total of 18 cases of COVID-19 prior to liver transplantation were reported. The mean age was 38.7±14.6, with male prevalence. Most had mild symptoms of COVID. Five patients have specific treatment for COVID-19 with convalescent plasm or remdesivir/oseltamivir, just one patient received hydroxychloroquine, and 12 patients received only symptomatic treatment. The median time between COVID-19 to LT was 19 days (13.5-44.5). Deceased donor liver transplantation accounted for 61% of cases, while living donor transplantation was 39%. Conclusion: Despite the concerns regarding the postoperative evolution, the mortality of patients with high MELD or fulminant hepatitis transplanted shortly after COVID-19 diagnosis does not seem to be higher.

Application of digital design combined with 3D-printing technologies in dental autotransplantation / 口腔疾病防治

Objective@#To evaluate the therapeutic effect of dental autotransplantation with the application of digital design combined with 3D printing of donor tooth models and recipient alveolar fossa model preoperatively.@*Methods@# Twelve cases that could not be retained due to tooth fracture or extensive absorption of alveolar bone were recruited in the study. Cone-beam computed tomography (CBCT) data were imported into Mimics software for digital design, and the best-matched third molar was selected as the donor tooth. Replicas of the donor teeth and the recipient socket were printed out with three-dimensional (3D) printing technologies as a simulation model for recipient tooth socket preparation. During tooth autotransplantation, preparation of the recipient tooth socket and the donor tooth were guided by the 3D-printed replicas sequentially. Then, the donor tooth was implanted into the recipient tooth pocket. Patients were followed up at 3, 6 and 12 months after the operation, with CBCT examination to evaluate the status of bone reconstruction and periodontal ligaments at each time point. @*Results@#Twelve patients were transplanted with an autogenous third molar with the apical foramen completely closed. Among them, 7 patients had alveolar fossa infection before the operation, of which 1 had extensive resorption of the alveolar bone due to the infection. All 12 patients recovered well after the operation and were followed up for at least 12 months. In total, 11 caseswere successful in tooth autotransplantation with normal mastication, and 1 case had root resorption 14 months postoperation.@*Conclusion@#Digital design combined with 3D printing technology can assistin the selection of thebest-matched donor tooth and preparation of the recipient socket before tooth transplantation proceduresand reduce the extra-alveolar exposure time of the donor tooth and number of trial placementsintothe alveolar fossa. Thus, this combined strategy can effectively improve the outcome of dental autotransplantation.

Impact of graft/recipient weight ratio on the prognosis of infants with whole liver transplantation / 中华器官移植杂志

Objective:To explore the impact of graft recipient weight ratio(GRWR)on pediatric whole liver transplantation in infants aged under 1 year.Methods:From January 2014 to December 2019, clinical data were retrospectively reviewed for 140 children aged under 1 year with whole liver transplantation.They were divided into 3 groups of low GRWR(GRWR<2.5%, 48 cases), middle GRWR(2.5%≤GRWR<5%, 73 cases)and high GRWR(GRWR≥5%, 19 cases). Basic profiles, major postoperative complications and survival rate of graft/recipient were compared.Results:There were 62 males and 78 females with an average age of (7.34±1.81)months and an average weight of(6.81±1.09)kg.The median GRWR was 3.27%(1.33%~8.12%). The higher level of GRWR, the greater age, weight and graft weight of donor in three groups and there was statistical difference ( P<0.05); operative duration, postoperative ICU stay and hospital stay were longer in low GRWR group than those in middle GRWR group and there was statistical difference( P<0.05); The incidence of postoperative hepatic artery thrombosis was higher in low GRWR group than that in middle GRWR group(31.3%vs 8.2%)and there was statistical difference( P<0.05); 4 cases of small-for-size syndrome occurred in low GRWR group, it was significantly different from the other two groups and there was statistical difference( P<0.05); the median follow-up period was(50.7±23.4)months.The survival rates of grafts at 3-month and 1/5-year were 89.6%, 91.8%, 100%; 87.5%, 87.7%, 100%; 87.5%, 87.7%, 100%and there was no inter-group difference( P>0.05). The survival rates of recipients at 3 months, 1 year and 5 years post-operation were 93.8%, 91.8%, 100%; 91.7%, 87.7%, 100%; 91.7%, 87.7%, 100%and there was no inter-group difference( P>0.05). Conclusions:Different from pediatric living donor transplantation, GRWR≥5%does not affect the survival rate of recipient/graft during whole liver transplantation.And GRWR<2.5%may boost the postoperative incidence of hepatic artery thrombosis and small liver syndrome.

Objective:To explore the safety of inactivating coronavirus disease 2019(covid-19)vaccine in liver transplantation(LT)recipients.Methods:Retrospective analysis was performed for clinical data of 151 LT recipients from March 2003 to October 2019.They had stable conditions and completed the course of covid-19 vaccine.Frequencies of pain at injection site, fatigue, headache and pruritus after vaccination were recorded.The safety profiles were compared between recipients with and without local and general adverse reactions after vaccination.At the same time, recipients completing two doses of covid-19 vaccines were grouped.According to vaccine companies, they were classified into Sinovac Biotech Ltd and Beijing Biological.Based upon more than or less than 60 years, they were grouped into <60 years and ≥60 years.The safety profiles of inactivating COVID-19 vaccine were compared in subgroups.Results:Among 151 eligible LT recipients, 98 of them were in group of age <60 years and 53 in group of age >60 years.The median period between vaccination and LT was 8.44(4.37, 12.39)years and the median concentration of tacrolimus 2.5(1.8, 3.9)ng/L.Eighty-three cases completed two doses of Sinovac Biotech Ltd(Sinovac Biotech Ltd group)and 40 cases Beijing Biological(Beijing Biological group); 14 cases had combined course of Sinovac Biotech Ltd and Beijing Biological, four recipients were vaccinated with inactivated vaccine from other companies and ten recipients did not know their inactivated vaccine' companies.After immunization, 24/151(15.9%)recipients had a local and general adverse reaction.The prevalence of pain at injection site, fatigue, headache and pruritus was 9.9%( n=15), 5.2%( n=8), 1.3%( n=2)and 0.7%( n=1)respectively.No significant differences existed in age( P=0.602), gender( P=0.752), period after LT( P=0.890), trough concentration of tacrolimus( P=0.377)or versions of covid-19 vaccine( P=0.582)between 24 cases with general adverse reaction and 127 without.Local and general reactions occurred in 16/83(19.3%)in Sinovac group and 5/40(12.5%)in Beijing Biological.There was no significant inter-group difference( P=0.769). There were 98 cases(64.9%)in <60 years group, 17 cases(17.3%)had local and general reaction, 53 cases(35.1%)in ≥60 years group and 7 cases(13.2%)had a local and systemic reaction.There was no significant inter-group difference( P=0.507). Conclusions:Covid-19 vaccine is safe for long-term survival LT recipients with normal liver function.Few participants present with mild fatigue and pain at injection site.

Clinical application of split liver transplantation technique / 器官移植

Currently, multiple difficulties exist in clinical liver transplantation, such as shortage of donor liver, increasing quantity of patients waiting for liver transplantation and lack of matching donors, etc. Some children and adult patients have little chance of undergoing liver transplantation, which also limits the development of liver transplantation. In this context, split liver transplantation emerges, in which 1 donor liver can be applied to 2 or even more recipients. It may effectively increase the utilization rate of donor liver and alleviate the shortage of donor liver. With the development of split liver transplantation, the survival rate of split liver transplantation is comparable to that of total liver transplantation. Multiple transplantation centers have routinely adopted split liver transplantation. In this article, the development of split liver transplantation, the selection and matching of donors and recipients, the split and reconstruction techniques of donor liver and postoperative complications were reviewed, aiming to provide reference for subsequent development of split liver transplantation in clinical practice and increase the chance of liver transplantation for more patients diagnosed with end-stage liver diseases.

Surgical technical innovations in pediatric liver transplantation / 器官移植

In recent decade, pediatric liver transplantation has developed rapidly in China due to the improvement of surgical techniques and postoperative management, which has been applied from several domestic liver transplantation centers to more than 10 provinces, cities and autonomous regions. The annual quantity of pediatric liver transplantation has exceeded 1 000 for 3 consecutive years, ranking first across the world. The technique of pediatric liver transplantation has been gradually oriented to precision medicine. The development of pediatric liver transplantation mainly focuses on the "grafts". In this article, the development characteristics and trends of pediatric liver transplantation were elucidated from the perspectives of different types of liver transplantation that expanded the source of donor liver, including split liver transplantation, auxiliary liver transplantation, Domino liver transplantation and liver transplantation with hyper-reduced grafts, as well as the application of minimally invasive surgical and microsurgical anastomosis techniques in pediatric liver transplantation, which represented by laparoscopic surgery and Da Vinci surgical system, aiming to provide reference for further improving the long-term survival rate of grafts and the quality of life of the recipients.

Preoperative screening of donors and recipients for living uterine transplantation: an observational study / 中华器官移植杂志

Objective:To summarize our institutional experiences of screening and selecting potential recipients and living donors for uterine transplantation at a single center.Methods:A total of 102 patients were diagnosed as absolute uterine factor infertility (AUFI). Depending upon the outcomes of previous trials, 8 modules were selected for surveying. A registration form was distributed for subjects at outpatient clinics or through telephone consultations for clinical trials of uterus transplantation between November 2018 and October 2019. The relevant information was collected and entered into a dedicated system for data processing.Results:The number of eligible subjects was 84 and the number of recipients with potential donors 37. The average age of potential recipients was 26.0(18-47) years. Among potential recipients, 76(90.5%) had congenital AUFI and 8(9.5%) acquired AUFI. For potential donors with available organs, the average age was 47.5(32-64) years and the proportion of menopausal or peri-menopausal status 56.8%.Conclusions:Currently large demands and sufficient supports for conducting clinical trials of uterine transplantation are available in China. However, inherent deficiencies persist in organ donor population reserves and preoperative screening protocols, such as donor age and subjective/objective factors of participants. During clinical trials of uterine transplantation, preoperative screening should be performed for expanding the screening scope, extending the screening time and popularizing the screening knowledge to boost the success rate.

Research progress on autologous fat transplantation in the treatment of velopharyngeal insufficiency / 口腔疾病防治

@#Autologous fat transplantation in the treatment of velopharyngeal insufficiency has the advantages of good histocompatibility, small local trauma, few complications, reversible operation and simple postoperative nursing, which can effectively increase the velopharyngeal closure area. If the clinical effect is poor, other surgical methods can be used at any time for replacement. Although there are many advantages in the treatment of velopharyngeal insufficiency with autologous fat transplantation, there are still some problems in the selection of indication, donor site, injection dose, recipient site, follow-up evaluation, complications and prevention and treatment. Current research shows that autologous fat transplantation is mainly used in patients with mild or moderate velopharyngeal insufficiency, but with the improvement of fat acquisition and treatment techniques, the indications for autologous fat transplantation continue to expand, and autologous fat transplantation combined with palatoplasty or pharyngoplasty has been proposed for the treatment of severe velopharyngeal insufficiency. However, there are complications, such as fat absorption and obstructive sleep apnea syndrome. In addition, the application of autologous fat transplantation in severe VPI patients and how to improve the long-term stability of autologous fat transplantation need further study.

Objective:Exploring the " bottle neck" factors in the scientific research management of recipient hospitals, making good use of counterpart support resources to help identifying appropriate, tailored strategies of scientific research management that might improve the research capacity of recipient hospitals.Methods:Data were collected according to questionnaire survey and on-site interview, ABC classification method were used to perform statistical analysis, and " bottleneck" factors that constraint the scientific research work of the recipient hospital were summarized.Results:" Insufficient scientific research skills and lacking of talents" and " lacking of scientific research environment and recognition" are the two most prominent factors that negatively affect the scientific research capacity building of the recipient hospitals, followed closely by " the out-dated scientific research policies and lacking support from the hospital leadership" , insufficient of research platform or resources including research funding, as well as other factors. Based on such findings, this article took the First People's Hospital of Kashgar (Guangdong counterpart support) as an example, and tried to discuss some corresponding measures on how to make good use of counterpart support resources.Conclusions:The ABC classification method were used to identify the main " bottleneck" factors, and a series of effective measures that help to making good use of counterpart support resources were explored. As a result, the efficiency of the scientific research management of the recipient hospitals, which in terms of management methods, management concepts and management models, were improved.

Comparison of split skin thickness graft survival in diabetic and non-diabetic ulcer

Background: Split skin grafting is widely used surgical procedure for the treatment of ulcers. Graft survival depends on number of factors like vascularity, wound infection etc, diabetes is associated with endothelial dysfunction, neuropathy, wound infection which collectively affect the graft survival. Objective of this study was to compare the amount of graft uptake, the post-operative complications and survival of split thickness skin graft in diabetic and non-diabetic ulcer.Methods: In our prospective comparative study total 112 patients with ulcer were included of which 56 were diabetic and 56 were non-diabetic. All of them underwent split skin grafting as part of their wound management. Comparison was made between two groups in terms of amount of graft uptake, post-operative wound infection, revisional surgery, donor site infection.Results: Compared with non-diabetics, diabetics have significantly less graft uptake (p<0.001). out of 56 patients in diabetic group 4 (66.7%) underwent revisional surgery, out of 56 patients in non-diabetic group 2 (33.3) patients underwent revisional surgery (p value is <0.68) which is statistically insignificant. 3 (60%) out of 56 in diabetic group developed post-operative graft infection, 2 (40%) out of 56 in non-diabetic group developed graft infection (p=1, not significant). One patient in the study developed donor site infection. Among 112 cases, only 1 case had donor site infection with diabetic.Conclusions: Diabetes is associated with poor graft uptake and post-operative complication rates in patients undergoing split skin grafting.

Twin-Twin transfusion syndrome: a case report

Twin to twin transfusion syndrome is a rare but serious complication of monochorionic twin pregnancy. It is characterized by the development of abnormal placental vascular communication from one foetus (donor) to the other foetus (recipient). If left untreated it led to high rates of perinatal morbidity and mortality due to its poorly understood etiology and difficulty in diagnosing and treatment. Authors report a case of twin to twin transfusion syndrome in 24 years old primigravida with gestational age of 18 weeks 5 days diagnosed on ultrasound.

COVID-19 in solid organ transplantation patients: A systematic review

Coronavirus disease (COVID-19) rapidly progresses to severe acute respiratory syndrome. This review aimed at collating available data on COVID-19 infection in solid organ transplantation (SOT) patients. We performed a systematic review of SOT patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The MEDLINE and PubMed databases were electronically searched and updated until April 20, 2020. The MeSH terms used were "COVID-19" AND "Transplant." Thirty-nine COVID-19 cases were reported among SOT patients. The median interval for developing SARS-CoV-2 infection was 4 years since transplantation, and the fatality rate was 25.64% (10/39). Sixteen cases were described in liver transplant (LT) patients, and the median interval since transplantation was 5 years. The fatality rate among LT patients was 37.5% (6/16), with death occurring more than 3 years after LT. The youngest patient who died was 59 years old; there were no deaths among children. Twenty-three cases were described in kidney transplant (KT) patients. The median interval since transplantation was 4 years, and the fatality rate was 17.4% (4/23). The youngest patient who died was 71 years old. Among all transplant patients, COVID-19 had the highest fatality rate in patients older than 60 years : LT, 62.5% vs 12.5% (p=0.006); KT 44.44% vs 0 (p=0.039); and SOT, 52.94% vs 4.54% (p=0.001). This study presents a novel description of COVID-19 in abdominal SOT recipients. Furthermore, we alert medical professionals to the higher fatality risk in patients older than 60 years.

Dilemas y vivencias frente a la implementación de la ley 1805 de 2016 / Dilemmas and experiences caused by the implementation of the law 1805 of 2016 / Dilemas e vivências perante a aplicação da lei 1805 de 2016

En Colombia la ley 1805/2016, amplía la presunción legal de donación de órganos de todo adulto que en vida no exprese su negativa ante esta. Diversos posicionamientos involucran aspectos éticos y bioéticos, intensificando el debate moral y jurídico que la normativa suscita. El objetivo es analizar los dilemas bioéticos, que emergen en el personal de salud frente a la presunción legal de donación de órganos y las vivencias de pacientes en lista de espera, en el marco de la implementación de la ley 1805/2016. Materiales y métodos. Estudio fenomenológico, con triangulación múltiple y abordaje cualitativo, mediante entrevistas semiestructuradas, conversatorios y grupos focales. Informantes claves: 7 pacientes en lista de espera y 19 profesionales de salud de tres unidades de cuidados intensivos. Resultados. Se encontró que la implementación normativa convoca un tercer actor, la red de trasplante, que poco interactúa con el equipo de salud durante el rescate de órganos, situación que genera dilemas entre el principio de justicia distributiva, que involucra a los pacientes en lista de espera y el principio de respeto ante el duelo de los familiares del fallecido. Las tensiones de los pacientes se relacionan con el trasplante, que representa una esperanza de vida, rodeada de múltiples requerimientos. En conclusión, el personal de salud afronta dilemas bioéticos, por falta de educación y sensibilización normativa. Los pacientes experimentan tensiones éticas, que se sustentan en las vivencias de conductas previas, frente al anhelo del trasplante, visualizado como una segunda oportunidad.

In Colombia, the law 1805/2016, extends the legal presumption of organ donation to all adults who during life do not express denial regarding this matter. Diverse positionings involve ethic and bioethics aspects, intensifying the moral and legal debate caused by this law. Objective: Analyze the bioethical dilemmas that emerge in the healthcare personnel regarding the presumption of legal donation and the experiences of patients in the waiting list, considering the law 1805/2016. Material and Methods: Phenomenological study with multiple triangulation and qualitative approach, through semi-structured interviews, round table discussions and focus groups. Key informants: 7 patients on the waiting list and 19 healthcare professionals from three intensive care units. Results: It was found that the implementation of this regulation convenes a third party, the organ and transplant network, which hardly interacts with the health team during the rescue of organs, a situation that generates dilemmas between the principle of distributive justice, involving the patients on the waiting list, and the principle of respecting the grief of the family of the deceased. The tensions of the patients are related to the transplant, which represents a hope for life, surrounded by multiple requirements. Conclusion: The health care personnel face bioethical dilemmas caused by the lack of education and sensibilization from the regulations. The patients experience ethical tensions, which are based on the experiences of previous behaviors regarding the longing for transplantation, visualized as a second opportunity.
