ABSTRACT

OBJECTIVES: Wilson disease is an inherited disorder that results in copper accumulation in the tissues with liver injury and failure. Orthotopic liver transplant is one of the treatments of choice for this disease. The aim of this study was to compare the neurological symptoms, before and after orthotopic livertransplant, of patients with liver cirrhosis due to Wilson disease, who represent a special group of patients with liver failure. MATERIALS AND METHODS: Between 2007 and 2020, there were 24 patients with Wilson disease resistant to medical treatment who underwent deceased donor orthotopic livertransplant and were followed up for 1 year, 5 years, and 10 years for evaluation with neurological scoring systems. Patients were also evaluated for postoperative complications and survival. RESULTS: Of the 24 patients evaluated, there were 13 (54.2%) female patients and 11 (45.8%) male patients, and the mean age was 34 years (range, 14-57 years). One of the patients died from early postoperative sepsis. After orthotopic livertransplant, disease scores returned to normal in 16 patients and improved in the remaining patients. Before transplant, all patients required help in their daily activities. After transplant, there were significant improvements in some symptoms, and the patients became more independent in their daily lives. CONCLUSIONS: Our study shows that orthotopic liver transplant provides significant improvement in neurological symptoms and quality of life in patients with Wilson disease.

ABSTRACT

BACKGROUND: COVID-19 has led to an unprecedented global health crisis. This situation caused an immediate reduction in solid organ transplantation activity. This study aimed to present the follow-up results of patients with chronic liver disease who underwent liver transplantation (LT) after a history of COVID-19 infection. METHODS: Sociodemographic characteristics and clinicopathological data of 474 patients who underwent LT at Inonu University Liver Transplant Institute between March 11, 2020 and March 17, 2022 were prospectively recorded and analyzed retrospectively. Among these, the data of 35 patients with chronic liver disease who were found to be exposed to COVID-19 infection in the pre-LT period were analyzed for this study. RESULTS: The median body mass index, Child score, and Model for end-stage liver disease/ Pediatric end-stage liver disease scores of the 35 patients were calculated as 25.1 kg/m2 (IQR: 7.4), 9 points (IQR: 4), and 16 points (IQR: 10), respectively. Graft rejection occurred in 4 patients at a median of 25 days post-transplant. Five patients underwent retransplantation at a median of 25 days post-transplant. The most common cause of retransplantation is early hepatic artery thrombosis. There were 5 deaths during postoperative follow-up. Mortality developed in 5 (14.3%) patients exposed to COVID-19 infection in the pretransplant period, whereas mortality occurred in 56 (12.8%) patients not exposed to COVID-19 infection. There was no statistically significant difference in mortality between the groups (P = .79). CONCLUSIONS: The results of this study showed that exposure to COVID-19 before LT does not affect post-transplant patients and graft survival.

ABSTRACT

Abnormal liver tests are common after liver transplantation. The differential diagnosis depends on the clinical context, particularly the time course, pattern and degree of elevation, and donor and recipient factors. The perioperative period has distinct causes compared with months and years after transplant, including ischemia-reperfusion injury, vascular thrombosis, and primary graft nonfunction. Etiologies seen beyond the perioperative period include biliary complications, rejection, infection, recurrent disease, and non-transplant-specific causes. The evaluation begins with a liver ultrasound with Doppler as well as appropriate laboratory testing and culminates in a liver biopsy if the imaging and laboratory testing is unrevealing.

ABSTRACT

OBJECTIVES: Coronavirus disease 2019 has resulted in significant morbidities and mortalities in nearly all parts ofthe world. There remain major concerns about management, timing, and safety of liver transplant in patients who have recovered from COVID-19. We aimed to study the clinical course and outcomes of patients with liver cirrhosis who recovered from COVID-19 and underwent liver transplant from deceased donors. MATERIALS AND METHODS: A retrospective study was conducted on liver transplant recipients who underwent liver transplant from April 1, 2020, to January 30, 2021. We evaluated all recipients of liver transplantfrom deceased donors during this period in the COVID-19 pandemic. RESULTS: There were 14 patients with decompensated liver cirrhosis who had recovered from COVID-19 as documented by reverse transcription-polymerase chain reaction test for SARS-CoV-2. Mean duration from COVID-19 to transplant surgery was 56.14 ± 29.96 days. Mortality occurred in 3 patients, and of whom 2 had been hospitalized and received medications for COVID-19 before transplant. Five patients had positive reverse transcription-polymerase chain reaction results for SARS-CoV-2 after liver transplant. CONCLUSIONS: This is a large reported series of patients with liver cirrhosis who have received liver transplant after recovery from COVID-19. We provided evidence that liver transplant from deceased donors should be considered in patients recovered from COVID-19, especially in those with deterioration of clinical status.

ABSTRACT

Despite the benefits of abdominal normothermic regional perfusion (A-NRP) for abdominal grafts in controlled donation after circulatory death (cDCD), there is limited information on the effect of A-NRP on the quality of the cDCD lungs. We aimed to study the effect of A-NRP in lungs obtained from cDCD and its impact on recipients´ outcomes. This is a study comparing outcomes of lung transplants (LT) from cDCD donors (September 2014 to December 2021) obtained using A-NRP as the abdominal preservation method. As controls, all lung recipients transplanted from donors after brain death (DBD) were considered. The primary outcomes were lung recipient 3-month, 1-year, and 5-year survival. A total of 269 LT were performed (60 cDCD and 209 DBD). There was no difference in survival at 3 months (98.3% cDCD vs. 93.7% DBD), 1 year (90.9% vs. 87.2%), and 5 years (68.7% vs. 69%). LT from the cDCD group had a higher rate of primary graft dysfunction grade 3 at 72 h (10% vs. 3.4%; p <  .001). This is the largest experience ever reported with the use of A-NRP combined with lung retrieval in cDCD donors. This combined method is safe for lung grafts presenting short-term survival outcomes equivalent to those transplanted through DBD.

ABSTRACT

BACKGROUND: Although many transplant programs have been forced to suspend living donor transplants due to the emergence of coronavirus disease (COVID-19), there are relatively few real-time databases to assess center-level transplant activities. We aimed to delineate the actual impact of COVID-19 on living donor transplant programs and the resumption process in Japan. METHODS: In a nationwide survey, questionnaires were sent to 32 liver transplant programs that had performed at least more than one case of living donor liver transplantation in 2019 and 132 kidney transplant programs that had performed more than one living donor kidney transplantation in 2018. RESULTS: Thirty-one (96.9%) and 125 (94.7%) liver and kidney transplant programs responded, respectively. In the early pandemic period, 67.7% (21/31) of liver programs and 29.8% (37/125) of kidney programs were able to maintain transplant activities similar to those during the pre-pandemic period. After temporal suspension, 58.1% of kidney programs resumed their transplant activity after the number of local COVID-19 cases peaked. Establishing institutional COVID-19 screening, triage, and therapeutic management protocols was mandatory to resume transplant activity for 64.5% and 67.7% of liver and kidney programs, respectively. In the future wave of COVID-19, 67.7% of liver programs would be affected by institutional COVID-19 intensive care unit-bound patient numbers, and 55.7% of kidney programs would stop if hospital-acquired severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection spreads. CONCLUSIONS: THIS NATIONWIDE SURVEY REVEALED FOR THE FIRST TIME HOW LIVING DONOR LIVER AND KIDNEY: transplant programs changed in response to the COVID-19 pandemic in a country where living donor transplantations are predominant.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has affected medical care worldwide. Thus, we aimed to assess the impact of the COVID-19 pandemic on pediatric LT recipients. METHODS: A cross-sectional study based on a structured internet or telephone survey was conducted among pediatric LT recipients. Survey results were compared with results of a survey conducted among pediatric patients with IBD. RESULTS: Seventy-six pediatric LT patients participated in the study. Of them, 58 (76.3%) reported fear of severe COVID-19 infection due to LT or LT-associated medications. Half of the patients reported needing emotional support. Most patients (51, 67.1%) reported strictly following official guidance, while more stringent protective measures were taken by 64 (84.2%) patients. None of the patients discontinued their medications due to COVID-19. Compared to pediatric patients with IBD, a higher proportion of pediatric LT recipients reported fears of contracting severe COVID-19 infection due to their illness or medications (45, 59.2% vs. 110, 45.1%). CONCLUSION: Among pediatric LT recipients a higher proportion reported fear of severe COVID-19 infection, implemented additional protective measures and expressed a need for emotional support, compared to patients with IBD. Medical teams should provide adequate information and offer a support system for this vulnerable population.

ABSTRACT

BACKGROUND: The suspension of the surgical activity, the burden of the infection in immunosuppressed patients, and the comorbidities underlying end-stage organ disease have impacted transplant programs significantly, even life-saving procedures, such as liver transplantation. METHODS: A review of the literature was conducted to explore the challenges faced by transplant programs and the adopted strategies to overcome them, with a focus on indications for imaging in liver transplant candidates. RESULTS: Liver transplantation relies on an appropriate imaging method for its success. During the Coronavirus Disease 2019 (COVID-19) pandemic, chest CT showed an additional value to detect early signs of SARS-CoV-2 infection and other screening modalities are less accurate than radiology. CONCLUSION: There is an emerging recognition of the chest CT value to recommend its use and help COVID-19 detection in patients. This examination appears highly sensitive for liver transplant candidates and recipients, who otherwise would have not undergone it, particularly when asymptomatic.

ABSTRACT

BACKGROUND: Coronavirus disease 2019 (Covid-19) pandemic is representing a massive burden to the community with the new virus. There is few data regarding Covid-19 in liver transplant patients. Concerns were raised regarding the course of the disease in transplanted patients due to immunosuppression and risk of hepatic injuries. AIM: To describe the outcomes of Covid-19 infection in recipients of living-donor liver transplantation (LDLT). METHODS: Retrospective analysis of 41 recipients of LDLT diagnosed with Covid-19 by real-time PCR or CT chest criteria of Covid-19 between April 2020 and April 2021. This Cohort was derived from Ain Shams Center for Organ Transplantation database, Ain Shams Specialized Hospital, Cairo, Egypt, which is considered one of the largest centers of LDLT in the Middle East. Patients were classified to mild, moderate, severe and critics according to clinical classification released by the National Health Commission of China. RESULTS: A total of 41 patients and 2 patients with reinfection were included in this cohort with mean age 54 years with 74% male and 26% female. The body mass index ranged from 19.3 to 37. About 30% were described as a mild case, 46.5% were moderate, 14% were severe and 9% were critical cases. Two cases developed infection twice. Total of 20 patients (46.5%) were managed in home isolation setting, 17 patients (39.5%) needed admission to ward, 4 patients (9%) in intermediate care unit and 2 patients (4%) admitted to intensive care unit. About 60% of cases were on room air, only 3 patients needed invasive methods, 2 patients needed face mask and 1 case needed invasive CPAP. In total, 41 patients recovered (95%) and 2 patients (5%) died; 1 was Covid related and the other one was non-Covid related. Female gender, higher BMI and hypertension were associated with severe course of the disease. CONCLUSION: In the setting of LDLT, the possibilities of catching Covid-19 infection are high due to chronic immunosuppression use. Yet, the outcome of infection in term of morbidity and the needs for hospital admission or intensive care is generally matched to general population.

ABSTRACT

BACKGROUND & AIMS: Two SARS-CoV-2 mRNA vaccines were approved to prevent COVID-19 infection, with reported vaccine efficacy of 95%. Liver transplant (LT) recipients are at risk of lower vaccine immunogenicity and were not included in the registration trials. We assessed vaccine immunogenicity and safety in this special population. METHODS: LT recipients followed at the Tel-Aviv Sourasky Medical Center and healthy volunteers were tested for SARS-CoV-2 IgG antibodies directed against the Spike-protein (S) and Nucleocapsid-protein (N) 10-20 days after receiving the second Pfizer-BioNTech BNT162b2 SARS-CoV-2 vaccine dose. Information regarding vaccine side effects and clinical data was collected from patients and medical records. RESULTS: Eighty LT recipients were enrolled. Mean age was 60 years and 30% were female. Twenty-five healthy volunteer controls were younger (mean age 52.7 years, p = 0.013) and mostly female (68%, p = 0.002). All participants were negative for IgG N-protein serology, indicating immunity did not result from prior COVID-19 infection. All controls were positive for IgG S-protein serology. Immunogenicity among LT recipients was significantly lower with positive serology in only 47.5% (p <0.001). Antibody titer was also significantly lower in this group (mean 95.41 AU/ml vs. 200.5 AU/ml in controls, p <0.001). Predictors for negative response among LT recipients were older age, lower estimated glomerular filtration rate, and treatment with high dose steroids and mycophenolate mofetil. No serious adverse events were reported in either group. CONCLUSION: LT recipients developed substantially lower immunological response to the Pfizer-BioNTech SARS-CoV-2 mRNA-based vaccine. Factors influencing serological antibody responses include age, renal function and immunosuppressive medications. The findings require re-evaluation of vaccine regimens in this population. LAY SUMMARY: The Pfizer-BioNTech BNT162b2 SARS-CoV-2 vaccine elicited substantially inferior immunity in liver transplant recipients. Less than half of the patients developed sufficient levels of antibodies against the virus, and in those who were positive, average antibody levels were 2x less compared to healthy controls. Factors predicting non-response were older age, renal function and immunosuppressive medications.

ABSTRACT

BACKGROUND & AIMS: Liver transplant (LT) recipients or other immunocompromised patients were not included in the registration trials studying the efficacy of vaccines against SARS-CoV-2. Although the clinical efficacy of COVID-19 vaccines in immunocompromised patients is unknown, many societies have recommended vaccination of this highly vulnerable patient population. METHODS: In this prospective study, we determined antibody responses to spike protein, 4 weeks after the 2nd dose of mRNA vaccines or after the single dose of Johnson & Johnson vaccine, in LT recipients and those with chronic liver disease (CLD) with and without cirrhosis. RESULTS: Of the 233 patients enrolled so far, 62 were LT recipients, 79 had cirrhosis (10 decompensated) and 92 had CLD without cirrhosis. Antibody titers were defined as undetectable (<0.40 U/ml), suboptimal (0.40-250 U/ml) and adequate (>250 U/ml). Of the 62 patients who had LT, antibody levels were undetectable in 11 patients and suboptimal (median titer 17.6, range 0.47-212 U/ml) in 27 patients. Among 79 patients with cirrhosis, 3 had undetectable antibody levels and 15 had suboptimal (median titer 41.3, range 0.49-221 U/L) antibody responses. Of the 92 patients without cirrhosis, 4 had undetectable antibody levels and 19 had suboptimal (median titer 95.5, range 4.9-234 U/L) antibody responses. Liver transplantation, use of 2 or more immunosuppression medications and vaccination with a single dose of the Johnson & Johnson vaccine were associated with poor immune response on multivariable analysis. No patient had any serious adverse events. CONCLUSIONS: Poor antibody responses after SARS-CoV-2 vaccination were seen in 61% of LT recipients and 24% of those with CLD. LAY SUMMARY: The clinical efficacy of COVID-19 vaccines in immunocompromised patients is unknown. We performed a prospective study to evaluate immune responses to COVID-19 vaccines (Moderna, Pfizer or Johnson & Johnson) in 62 liver transplant recipients, 79 patients with cirrhosis and 92 with chronic liver diseases without cirrhosis. We found that 17.8% of liver transplant recipients, 3.8% of those with cirrhosis and 4.3% of those with chronic liver diseases without cirrhosis had undetectable antibody levels. In total, 61.3% of liver transplant recipients and 24% of those with chronic liver diseases (with or without cirrhosis) had poor antibody responses (undetectable or suboptimal). Liver transplantation, use of immunosuppressive medications and vaccination with a single dose of Johnson & Johnson vaccine were associated with poor antibody responses when adjusted for other factors.

ABSTRACT

The COVID-19 pandemic and social justice movement have highlighted the impact of social determinants of health (SDOH) and structural racism in the United States on both access to care and patient outcomes. With the evaluation for liver transplantation being a highly subjective process, there are multiple ways for SDOH to place vulnerable patients at a disadvantage. This policy corner focuses on three different methods to reverse the deleterious effects of SDOH-identify and reduce implicit bias, expand and optimize telemedicine, and improve community outreach.

ABSTRACT

PURPOSE OF REVIEW: To assess the impact of coronavirus disease 2019 (COVID-19) and the pandemic on liver transplant candidates, recipients, and donors, and review guidelines and recommendations for integrating COVID-19 therapies into current practice. RECENT FINDINGS: COVID-19 has high morbidity and mortality for transplant candidates; interestingly, posttransplant comorbidities play a larger role than immunosuppression status. COVID-19 therapies and vaccinations are well tolerated in pre and postliver transplant patients with few exceptions, although further research is needed regarding effectiveness in this patient population. Provider practice patterns should evolve to minimize contagion during the current pandemic and prepare for an increase in liver disease due to after-shocks of missed diagnosis and progression of liver disease. SUMMARY: COVID-19 has spurred new research and technologies to ensure the safety of liver transplant candidates, recipients, and donors, and most COVID-19 therapies are safe in this patient population. Further work needs to be done regarding the use of COVID-19 positive organs and the efficacy of vaccines in the transplant population.

ABSTRACT

Coronavirus disease 2019 is a global pandemic, and to deal with the unexpected, enormous burden on healthcare system, liver transplantation (LT) services have been suspended in many centers. Development of robust and successful protocols in preventing the disease among the recipients, donors and healthcare workers would help in re-starting the LT programs. We adapted a protocol at our center, which is predominantly a living donor liver transplant center based in north India, and continued the service as the pandemic unfolded and peaked in India with good results and shared the experience of the same. Between March 24 and June 7, 2020, during the government-enforced public curfew-"lockdown"-7 children received LT. The protocols of infection control were drafted in our team by local customization of published guidelines. The number of pediatric LT done during the lockdown period in 2020 was similar to that done in corresponding pre-COVID period in 2019. The outcomes were of 100% survival, and none of recipients developed COVID. One potential donor was asymptomatic positive for COVID, responded well to conservative treatment, and was later accepted as a donor. LT program during the COVID pandemic can successfully function after putting in place standard protocols for infection control. These can be implemented with minimal extra involvement of healthcare infrastructure, hence without diversion of resources from COVID management. In conclusion, pediatric liver transplantation services can be continued amid COVID-19 pandemic after establishing a properly observed protocol with minimum additional resources.

ABSTRACT

Pulmonary disease in liver cirrhosis and portal hypertension (PH) constitutes a challenging clinical scenario and may have important implications with regard to prognosis, liver transplantation (LT) candidacy, and post-LT outcome. Pre-LT evaluation should include adequate screening for pulmonary diseases that may occur concomitantly with liver disease as well as for those that may arise as a complication of end-stage liver disease and PH, given that either may jeopardize safe LT and successful outcome. It is key to discriminate those patients who would benefit from LT, especially pulmonary disorders that have been reported to resolve post-LT and are considered "pulmonary indications" for transplant, from those who are at increased mortality risk and in whom LT is contraindicated. In conclusion, in this article, we review the impact of several pulmonary disorders, including cystic fibrosis, alpha 1-antitrypsin deficiency, hereditary hemorrhagic telangiectasia, sarcoidosis, coronavirus disease 2019, asthma, chronic obstructive pulmonary disease, pulmonary nodules, interstitial lung disease, hepatic hydrothorax, hepatopulmonary syndrome, and portopulmonary hypertension, on post-LT survival, as well as the reciprocal impact of LT on the evolution of lung function.

ABSTRACT

According to a recent World Health Organization estimate, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, which originated in China in 2019, has spread globally, infecting nearly 100 million people worldwide by January 2021. Patients with chronic liver diseases (CLD), particularly cirrhosis, hepatobiliary malignancies, candidates for liver transplantation, and immunosuppressed individuals after liver transplantation appear to be at increased risk of infections in general, which in turn translates into increased mortality. This is also the case for SARS-CoV-2 infection, where patients with cirrhosis, in particular, are at high risk of a severe COVID-19 course. Therefore, vaccination against various pathogens including SARS-CoV-2, administered as early as possible in patients with CLD, is an important protective measure. However, due to impaired immune responses in these patients, the immediate and long-term protective response through immunisation may be incomplete. The current SARS-CoV-2 pandemic has led to the exceptionally fast development of several vaccine candidates. A small number of these SARS-CoV-2 vaccine candidates have already undergone phase III, placebo-controlled, clinical trials in healthy individuals with proof of short-term safety, immunogenicity and efficacy. However, although regulatory agencies in the US and Europe have already approved some of these vaccines for clinical use, information on immunogenicity, duration of protection and long-term safety in patients with CLD, cirrhosis, hepatobiliary cancer and liver transplant recipients has yet to be generated. This review summarises the data on vaccine safety, immunogenicity, and efficacy in this patient population in general and discusses the implications of this knowledge on the introduction of the new SARS-CoV-2 vaccines.

ABSTRACT

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has seen transplant volume decrease nationwide, resulting in a 2.2-fold increase in waitlist mortality. In particular, solid organ transplant patients are subjected to increased morbidity and mortality from infection. In the face of these challenges, transplant centers need to develop innovative protocols to ensure high-quality care. METHODS: A multidisciplinary protocol was developed that included the following: virtual selection meetings, coronavirus disease 2019 negative donors, pretransplant symptom screening, rapid testing on presentation, telehealth follow-up, and weekly community outreach town halls. All orthotopic liver transplants completed between January 2018 and August 2020 were included in the study (n = 344). The cohort was stratified from January 2018 to February 2020 as "pre-COVID-19," and from March 2020 to August 2020 as "COVID-19." Patient demographics and postoperative outcomes were compared. RESULTS: From March 2020 to August 2020, there was a significant decrease in average monthly referrals for orthotopic liver transplantation (29.8 vs 37.1, P = .01). However, listings (11.0 vs 14.3, P = .09) and transplant volume remained unchanged (12.2 vs 10.6, P = .26). Rapid testing was utilized on arrival for transplant, zero patients tested positively preoperatively, and median time from test result until abdominal incision was 4.5 h [interquartile range, 1.2, 9.2]. Simultaneously, telehealth visits increased rapidly, peaking at 85% of all visits. It is important to note that there was no difference in outcomes between cohorts. CONCLUSION: Orthotopic liver transplant can be accomplished safely and effectively in the COVID-19 era without compromising outcomes through increasing utilization of telehealth, rapid COVID-19 testing, and multidisciplinary protocols for managing immunosuppressed patients.

ABSTRACT

INTRODUCTION: Living-donor liver transplantation (LDLT) has been mostly suspended and deceased-donor living transplantation activity has been considerably reduced because of coronavirus disease 2019 (COVID-19). We modified our protocols and procedures in line with COVID-19 guidelines. Since the restructuring, we have performed 20 LDLTs. Our study reports the outcomes of these cases and demonstrates the feasibility of LDLT during this pandemic. MATERIALS AND METHODS: The changes were influenced by experiences and communications from across the globe. A month-long self-imposed moratorium was spent in restructuring the program and implementing new protocols. Twenty LDLTs were performed between April 18 and September 15 using the new protocols. Our experience includes 2 simultaneous liver-kidney transplants, 1 ABO-incompatible LDLT, and 1 pediatric case (age 11 months). RESULTS: Nineteen patients recovered and 1 patient died. We maintained our postoperative immunosuppression protocol without many changes. Major complications were observed in 30% of recipients but none of the donors. One recipient was infected with COVID-19 during the postoperative period. A donor-recipient couple contracted COVID-19 after discharge from the hospital. All patients recovered from COVID-19 and liver enzymes were unaffected. CONCLUSION: This study represents a microcosm of experience in LDLT during the COVID-19 era. Outcomes of LDLT are not affected by COVID-19 per se, provided that we make necessary changes.
