Nintedanib in idiopathic and secondary pleuroparenchymal fibroelastosis.

BACKGROUND: Pleuroparenchymal fibroelastosis (PPFE) has a variable disease course with dismal prognosis in the majority of patients with no validated drug therapy. This study is to evaluate the effect of nintedanib in patients with idiopathic and secondary PPFE. Patients admitted to a tertiary care center (2010-2019) were included into this retrospective analysis if they had a multidisciplinary diagnosis of PPFE, had been followed-up for 3 months or more, and had lung function tests and chest CTs available for review. Changes in pulmonary function tests were assessed using non-parametric tests and linear mixed effect model. Lung volumes were measured with lobar segmentation using chest CT. RESULTS: Out of 21 patients with PPFE, nine had received nintedanib, six had received another treatment and another six patients were monitored without drug therapy. Annual FVC (% of predicted) relative decline was - 13.6 ± 13.4%/year before nintedanib and - 1.6 ± 6.02%/year during nintedanib treatment (p = 0.014), whereas no significant change in FVC% relative decline was found in patients receiving another treatment (- 13.25 ± 34 before vs - 16.61 ± 36.2%/year during treatment; p = 0.343). Using linear mixed effect model, the slope in FVC was - 0.97%/month (95% CI: - 1.42; - 0.52) before treatment and - 0.50%/month (95% CI: - 0.88; 0.13) on nintedanib, with a difference between groups of + 0.47%/month (95% CI: 0.16; 0.78), p = 0.004. The decline in the upper lung volumes measured by CT was - 233 mL/year ± 387 mL/year before nintedanib and - 149 mL/year ± 173 mL/year on nintedanib (p = 0.327). Nintedanib tolerability was unremarkable. CONCLUSION: In patients with PPFE, nintedanib treatment might be associated with slower decline in lung function, paving the way for prospective, controlled studies.

Incidence, management and outcome of respiratory syncytial virus infection in adult lung transplant recipients: a 9-year retrospective multicentre study.

OBJECTIVES: To analyse functional outcome parameters according to antimicrobial treatments after respiratory syncytial virus (RSV)-confirmed infection in adult lung transplant recipients. METHODS: A 9-year retrospective multicentre cohort study (2011-19) included adult lung transplant recipients with RSV-confirmed infection. The first endpoint determined new allograft dysfunction (acute graft rejection and chronic lung allograft dysfunction (CLAD)) 3 months after infection. Then baseline and 3 months' postinfection forced expiratory volume in 1 second (FEV1) values were compared according to antimicrobial treatment. Univariate logistic regression analysis was performed. RESULTS: RSV infection was confirmed in 77 of 424 lung transplant recipients (estimated incidence of 0.025 per patient per year; 95% confidence interval 0.018-0.036). At 3 months, 22 recipients (28.8%) developed allograft dysfunction: ten (13%) possible CLAD, six (7.9%) acute rejection and six (7.9%) CLAD. Recipients with the lowest preinfection FEV1 had a greater risk of developing pneumonia (median (interquartile range) 1.5 (1.1-1.9) vs. 2.2 (1.5-2.4) L/s, p 0.003) and a higher odds of receiving antibiotics (1.6 (1.3-2.3) vs. 2.3 (1.9-2.5) L/s, p 0.017; odds ratio 0.52, 95% confidence interval 0.27-0.99). Compared to tracheobronchitis/bronchiolitis, RSV-induced pneumonia led more frequently to hospitalization (91.7%, 22 vs. 58.0%, 29, p 0.003) and intensive care unit admission (33.3%, 8 vs. 0, p < 10-3). For ribavirin-treated recipients (24.7%, 19) and azithromycin prophylaxis (50.6%, 39), 3-month FEV1 values were not different from untreated recipients. The overall mortality was 2.5% at 1 month and 5.3% at 6 months, unrelated to RSV. CONCLUSIONS: At 3 months after RSV-confirmed infection, 22 recipients (28.8%) had new allograft dysfunction. Ribavirin treatment and azithromycin prophylaxis did not prevent FEV1 decline.

Measurement of glomerular filtration rate in lung transplant recipients highlights a dramatic loss of renal function after transplantation.

BACKGROUND: Chronic kidney disease (CKD) after lung transplantation (LT) is underestimated. The aim of the present study was to measure the loss of glomerular filtration rate (GFR) 1 year after LT and to identify the risk factors for developing Stage ≥3 CKD. METHODS: LT patients in the University Hospital of Lyon had a pre- and post-transplantation measurement of their GFR (mGFR), and GFR was also estimated using the Chronic Kidney Disease Epidemiology Collaboration equation. RESULTS: During the study period, 111 patients were lung transplant candidates, of which 91 had a pre-transplantation mGFR, and 29 had a mGFR at 1 year after LT. Six patients underwent maintenance haemodialysis after transplantation. Mean mGFR was 106 mL/min/1.73 m2 before LT and 58 mL/min/1.73 m2 1 year after LT (P < 0.05) with a mean loss of 48 mL/min/1.73 m2 per patient. The risk of developing Stage ≥3 CKD after LT was higher in patients with lower pre-LT mGFR (odds ratio for each 1 mL/min/1.73 m2 increase: 0.94, 95% confidence interval 0.88-0.99). Receiver operator characteristics curves for the sensitivity and specificity of eGFR and mGFR for the prediction of CKD Stage ≥3 after LT found that pre-LT mGFR of 101 mL/min/1.73 m2 and pre-LT eGFR of 124 mL/min/1.73 m2 were the optimal thresholds for predicting Stage ≥3 CKD after LT. CONCLUSION: The present study underlines the value of mGFR in the pre-LT stage and found major renal function loss after LT, and consequently two-thirds of patients have Stage ≥3 CKD at 1 year. All patients with a pre-LT mGFR <90 mL/min/1.73 m2 warrant particular attention.

Fast-Growing Alveolar Echinococcosis Following Lung Transplantation.

Alveolar echinococcosis is a rare but life-threatening infection caused by the parasite Echinococcus multilocularis. Its natural history is characterized by a slow parasitic growth over several years. Increased incidence and shorter development delay have been reported in immune-compromised patients. We report the reactivation of aborted lesions within 12 months of lung transplantation leading to a fast-growing aggressive hepatic lesion. Timely identification of alveolar echninococcosis allowed prompt albendazole treatment and radical surgery leading to a favorable outcome 42 months after transplantation. However, close clinical, serological and radiological monitoring is required to rule out relapses in the long term. The pre-existence of aborted self-limited lesions of alveolar echinococcosis and the possibility for their atypical rapid growth in patients undergoing profound immunosuppression should be known by healthcare providers, even if working in non-endemic areas.

Airway complications after lung transplantation: benefit of a conservative bronchoscopy strategy.

BACKGROUND: After lung transplantation (LT), between 2% and 25% of bronchial anastomoses develop complications requiring therapeutic intervention. The status of healing of both bronchial anastomoses and downhill airways are well described by the French consensual MDS standardized grading system (Macroscopic, Diameter, Suture). We analyzed risks factors for airway complications (AC) after transplantation and the way we managed them. We report here our challenging method of early rigid bronchoscopic intervention with airway stenting on bronchial healing. METHODS: All single center consecutives LTs were retrospectively analyzed between 2010-2016. Patient-level data (demographic, peri-operative data) and anastomosis-level data (surgical parameters, bronchoscopy findings) were monitored. The incidence and contributive factors of ACs are reported. We also reported modalities of the conservative treatment and outcome. RESULTS: A total of 121 LTs were performed, 39 single-lung and 82 bilateral sequential LT. Main indication for LT were cystic fibrosis (45%) and emphysema (25%) and 58 were male patients (n=70). After a waiting period of healing, 28 patients presented AC on 41 anastomoses (prevalence: 23%). A multivariate analysis found as contributive factors of ACs, post-operative infection by Aspergillus [odds ratio (OR) 2.7, 95% confidence interval (CI): 1.08-6.75; P=0.033] at the patient level, and at the anastomosis level, emphysema (OR 2.4, 95% CI: 1.02-5.6; P=0.045), early dehiscence (OR 11.2, 95% CI: 1.7-76; P=0.01) and cold ischemia time >264 min (OR 2.45, 95% CI: 1.08-5.6; P=0.03). All the 41 ACs were managed conservatively with rigid bronchoscopy (range, 1-10), 41 stents (21 in silicone and 20 fully-covered Silicone Expandable Metallic Stents) without major complication. Two AC were still under regular bronchoscopic care and silicone stenting for long left bronchus reason. No surgical intervention was needed. The 2-years overall survival rate where not different between AC group and controls, respectively 85% and 81%. CONCLUSIONS: Airway healing after transplantation remains a scalable process and the French consensual MDS classification helped us for therapeutic decisions. Rigid bronchoscopy and safety use of current stenting devices may have the pivotal role in the conservative management of ACs, avoiding perilous situation of surgery for AC. Despite a high rate of AC, their favorable evolution may be explained by the cautious care of airway healing and maybe by the use of the Celsior antioxidant solution.

Esophageal Motility Disorders Associated With Death or Allograft Dysfunction After Lung Transplantation? Results of a Retrospective Monocentric Study.

OBJECTIVES: Pathological gastroesophageal reflux (GER) is a known risk factor for bronchiolitis obliterans syndrome (BOS) after lung transplantation. This study aimed at determining whether functional esophageal evaluation might predict BOS occurrence and survival in this setting. METHODS: Ninety-three patients who underwent esophageal high-resolution manometry and 24-hour pH-impedance monitoring within the first year after lung transplantation were retrospectively included. A univariable analysis was performed to evaluate the parameters associated with GER disease and BOS occurrence. The Cox regression model was used to identify the prognostic factors of death or retransplantation. RESULTS: Thirteen percent of patients exhibited major esophageal motility disorders and 20% pathological GER. GER occurrence was associated with younger age, cystic fibrosis, and hypotensive esophagogastric junction. Within a median follow-up of 62 months, 10 patients (11%) developed BOS, and no predictive factors were identified. At the end of the follow-up, 10 patients died and 1 underwent retransplantation. The 5-year cumulative survival rate without retransplantation was lower in patients with major esophageal motility disorders compared with that in those without (75% vs 90%, P = 0.01) and in patients who developed BOS compared with that in those without (66% vs 91%; P = 0.005). However, in multivariable analysis, major esophageal motility disorders and BOS were no longer significant predictors of survival without retransplantation. DISCUSSION: Major esophageal motility disorders and BOS were associated with allograft survival in lung transplantation in the univariable analysis. Although the causes of this association remain to be determined, this observation confirms that esophageal motor dysfunction should be evaluated in the context of lung transplantation.

Cystic fibrosis-related diabetes before lung transplantation is associated with lower survival but does not affect long-term renal function.

OBJECTIVE: To describe the prevalence of cystic fibrosis-related diabetes (CFRD) before and after lung transplantation (LT); to analyse the survival and renal function after LT according to the CFRD status before LT. METHODS: Sixty cystic fibrosis (CF) patients transplanted at the Lyon University Hospital between 2004 and 2014 were included. Genotype, pancreatic status, age at LT, survival were recorded. Glucose tolerance status, daily insulin dose requirement, glomerular filtration rate (GFR), and daily glucocorticoid (GC) dose were recorded before LT and until December 2016. RESULTS: The median follow-up was 5.6 (3.8-8.2) years, and nine patients died. Survival was poorest for patients with CFRD before LT compared with those without CFRD (P = 0.03) but was not correlated with the GFR before LT, with sex, age at LT, or CF genotype. The prevalence of CFRD was 68% at 2 years and 54% at 5 years. For persistent insulin-treated CFRD, the insulin requirement decreased (-2.1 IU/d/y; P < 0.01) and was correlated with the daily GC dose (+0.4 IU/d for one additional milligram, P = 0.012). Seven (11%) patients who had insulin-treated CFRD before LT became nondiabetic after LT, with a median time of 2 (1-4) years. After LT, the GFR decreased (-5.3 ml/min/1.73 m 2 /y; P < 0.001) and was not correlated with the CFRD status before LT. CONCLUSIONS: CFRD before LT is associated with poor survival after LT, which should lead to better management of diabetes. Some patients with pre-LT CFRD became nondiabetic after LT. CFRD is not associated with renal insufficiency after LT.

Impact of comorbidities and delay in diagnosis in elderly patients with pulmonary hypertension.

Patient age at diagnosis of pulmonary hypertension is steadily increasing. The present study sought to analyse clinical characteristics, time to diagnosis and prognosis of pulmonary hypertension in elderly and very elderly patients. A study was conducted in a French regional referral centre for pulmonary hypertension. All consecutive patients diagnosed with pre-capillary pulmonary hypertension were included and categorised according to age: <65 years ("young"), 65-74 years ("elderly") and ≥75 years ("very elderly"). Over a 4-year period, 248 patients were included: 101 (40.7%) were young, 82 (33.1%) were elderly and 65 (26.2%) were very elderly. The median age at diagnosis among the total population was 68 years. Compared with young patients, elderly and very elderly patients had a longer time to diagnosis (7±48, 9±21 and 16±32 months, respectively; p<0.001). Patients ≥75 years also more often had group 4 pulmonary hypertension. The median overall survival was 46±1.4 months, but was only 37±4.9 months in elderly patients and 28±4.7 months in very elderly patients. Survival from the first symptoms and survival adjusted to comorbidity was similar across age groups. Patient age should be taken into account when diagnosing pulmonary hypertension as it is associated with a specific clinical profile and a worse prognosis. The difference in prognosis is likely to be related to a delay in diagnosis and a greater number of comorbidities.

Safety of right heart catheterization for pulmonary hypertension in very elderly patients.

Right heart catheterization (RHC) is the reference test in diagnosing pulmonary hypertension (PH). The increasing age of patients at the time of diagnosis raises the issue of the morbidity of this invasive test in elderly individuals. We hypothesized that the morbidity associated with RHC would be increased in elderly patients and highlight differences in hemodynamic characteristics compared to younger patients. A retrospective study was conducted in a regional referral center for PH. Data for all consecutive RHCs performed during the study period were analyzed. Over a five-year period, 1060 RHCs were performed. Of the patients, 228 (21.5%) were aged ≥75 years and 832 (78.5%) were aged <75 years. Duration of the procedure and site of puncture did not differ according to age group (all P > 0.05). Nine procedures (0.9%) led to complications: three (1.3%) in patients aged >75 years and six (0.7%) in younger patients aged ( P = 0.5). Eight were local vascular injuries, directly related to a femoral vein puncture ( P < 0.001). Pulmonary arterial pressure and cardiac output were lower in patients aged >75 years than in younger patients ( P = 0.001). RHC may be performed regardless of patient age. The rate of RHC complications is not increased in individuals aged >75 years. As most complications were related to femoral vein puncture, this route should be avoided whenever possible.

Pulmonary hypertension in chronic lung diseases: comparison to other pulmonary hypertension groups.

Group 3 pulmonary hypertension (PH) is a common complication of advanced chronic lung disease. Our hypothesis was that group 3 PH is associated with a more severe baseline presentation and a more severe prognosis compared to group 1 pulmonary arterial hypertension (PAH), chronic thromboembolic PH (group 4), and group 5 PH. We retrospectively analyzed consecutive incident PH patients in a single center between January 2006 and November 2014. Data were acquired from a prospective database. Clinical, functional, and hemodynamic characteristics, as well as survival, were compared between the four groups of precapillary PH. A total of 363 patients were analyzed; 164 patients (45.2%) belonged to group 1 PAH, 109 (30%) to group 3 PH, 65 (17.9%) to group 4 PH, and 25 (6.9%) to group 5 PH. Group 3 patients were predominantly male and were more frequently in New York Heart Association (NYHA) class III/IV. Patients with group 3 and 4 PH were older, had significantly lower 6-min walking distance (6MWD), higher mean pulmonary arterial pressure, higher pulmonary vascular resistance (PVR), and lower cardiac index (CI) than PAH patients. Group 3 and 5 patients had significantly lower total lung capacity (TLC), forced vital capacity (FVC), and FEV1; group 3 patients had the lowest carbon monoxide transfer coefficient values. PH therapy was used in 90.9% of group 3 patients. Univariate analysis of prognostic factors in the overall population showed that age, male gender, NYHA class, groups 3 and 4 PH (vs. PAH), 6MWD, FVC, TLC, carbon monoxide transfer coefficient (KCO), PVR, CI, and venous oxygen saturation were significantly associated with greater mortality. Multivariate analysis showed that age, PH group 4, 6MWD, and KCO but no longer PH group 3 were significantly associated with mortality. Patients with group 3 PH are older, have more severe baseline presentation and lower survival rates than PAH patients in univariate analysis, that seemed to be related to older age.

Lung transplantation after allogeneic stem cell transplantation: a pan-European experience.

Late-onset noninfectious pulmonary complications (LONIPCs) affect 6% of allogeneic stem cell transplantation (SCT) recipients within 5 years, conferring subsequent 5-year survival of 50%. Lung transplantation is rarely performed in this setting due to concomitant extrapulmonary morbidity, excessive immunosuppression and concerns about recurring malignancy being considered contraindications. This study assesses survival in highly selected patients undergoing lung transplantation for LONIPCs after SCT.SCT patients undergoing lung transplantation at 20 European centres between 1996 and 2014 were included. Clinical data pre- and post-lung transplantation were reviewed. Propensity score-matched controls were generated from the Eurotransplant and Scandiatransplant registries. Kaplan-Meier survival analysis and Cox proportional hazard regression models evaluating predictors of graft loss were performed.Graft survival at 1, 3 and 5 years of 84%, 72% and 67%, respectively, among the 105 SCT patients proved comparable to controls (p=0.75). Sepsis accounted for 15 out of 37 deaths (41%), with prior mechanical ventilation (HR 6.9, 95% CI 1.0-46.7; p<0.001) the leading risk factor. No SCT-specific risk factors were identified. Recurring malignancy occurred in four patients (4%). Lung transplantation <2 years post-SCT increased all-cause 1-year mortality (HR 7.5, 95% CI 2.3-23.8; p=0.001).Lung transplantation outcomes following SCT were comparable to other end-stage diseases. Lung transplantation should be considered feasible in selected candidates. No SCT-specific factors influencing outcome were identified within this carefully selected patient cohort.

Severe hematologic complications after lung transplantation in patients with telomerase complex mutations.

BACKGROUND: Mutations in the telomerase complex (TERT and TR) are associated with pulmonary fibrosis and frequent hematologic manifestations. The aim of this study was to characterize the prognosis of lung transplantation in patients with TERT or TR mutations. METHODS: Patients with documented TERT or TR mutations who received a lung transplant between 2007 and 2013 in France were identified via an exhaustive search of the lung transplantation network, one expert genetic laboratory, and the clinical research network on rare pulmonary diseases. RESULTS: There were 9 patients (7 men) with TERT (n = 6) or TR (n = 3) mutations who received a single (n = 8) or a double (n = 1) lung transplant for pulmonary fibrosis. Median age was 50 years (range, 35-61 years) at diagnosis and 52 years (range, 37-62 years) at the time of lung transplantation. Thrombocytopenia was present in 7 patients before lung transplantation. After lung transplantation, 6 patients developed myelodysplasia and/or bone marrow failure, directly contributing to death in 4 cases. Anemia was observed in 9 patients, and neutropenia was observed in 3 patients. The median survival after lung transplantation was 214 days (range, 59-1,709 days). CONCLUSIONS: Patients with mutations of the telomerase complex are at high risk of severe hematologic complications after lung transplantation, in particular, bone marrow failure. Specific recommendations should be developed for appropriate guidance regarding hematologic risk assessment before transplantation and management of the post-transplantation immunosuppressive regimen.

Chronic necrotising pulmonary aspergillosis: an uncommon aetiology of pneumothorax.

Pneumothorax is a frequent cause of admission in an emergency department. It can be due to a leakage of air from an air-filled lung cavitation into the pleural space. We report the unusual case of pneumothorax in a patient with a pulmonary cavitary infectious process mimicking tuberculosis. A 30-year-old asthmatic man, treated for several years with low-dose inhaled corticosteroids, presented a complete left tension pneumothorax and chronic necrotising pulmonary aspergillosis that mimicked initial pulmonary tuberculosis. Antifungal treatment by voriconazole was started and continued for 1 year, with a favourable outcome. This case highlights that chronic necrotising pulmonary aspergillosis is a diagnosis that should be considered in patients with a clinical presentation of pulmonary tuberculosis or in patients experiencing pneumothorax, especially in the context of corticosteroid treatment.

A new endoscopic standardized grading system for macroscopic central airway complications following lung transplantation: the MDS classification.

OBJECTIVES: After lung transplant, between 9 and 13% of bronchial anastomoses develop complications severe enough to warrant therapeutic intervention. These complications include stenosis, dehiscence, granulation tissue, bronchomalacia and fistula. Most of these have already been included in a classification or another, but none of these have been universally accepted. Moreover, no grading system has integrated all of these complications. The Groupe Transplantation (GT) (Transplant Group), from the Société de Pneumologie de Langue Française (SPLF) [French Language Pulmonology Society], maintains a prospective national registry of lung transplants performed in France. The GT has mandated the Groupe d'Endoscopie de Langue Française (GELF), also from the SPLF, to develop an endoscopic classification, in order to describe the macroscopic aspect of the bronchial anastomoses, and downhill airways, using a standardized and exhaustive grading system. METHODS: An endoscopic classification that would take into account the three major aspects of the description of bronchial anastomoses was elaborated. The first parameter is the macroscopic aspect (M), the second, the diameter (D) of the anastomosis and the third, the sutures (S) of the anastomosis. This classification was then submitted to expert bronchoscopists from nine centres, responsible for lung transplants in France, for their opinion, using a five-item questionnaire, according to the Delphi methodology. RESULTS: After the first round of consultation, all experts (100%) agreed on Questions 1 and 4. Answers were positive for Questions 2 (59%), 3 (56.25%) and 5 (70%). A modified classification, incorporating propositions from the first round, was then submitted. This second round allowed a consensus to be reached between all experts: the MDS classification. Each parameter (M, D and S) can be classified from 0 to 3. For M and D, it is possible to determine the extent of abnormalities downhill from the anastomosis into four subgroups (a, b, c or d). For S, the localization of abnormalities can be divided between two subgroups (e and f). CONCLUSION: The MDS classification, established by a consensus of French experts in bronchoscopy, could represent a standardized, universally acceptable system to describe central airway complications after lung transplant.

Absence of airway secretion accumulation predicts tolerance of noninvasive ventilation in subjects with amyotrophic lateral sclerosis.

OBJECTIVE: To assess factors that predict good tolerance of noninvasive ventilation (NIV), in order to improve survival and quality of life in subjects with amyotrophic lateral sclerosis. METHODS: We conducted a prospective study in subjects with amyotrophic lateral sclerosis and requiring NIV. The primary end point was NIV tolerance at 1 month. Subjects, several of whom failed to complete the study, were classified as "tolerant" or "poorly tolerant," according to the number of hours of NIV use (more or less than 4 h per night, respectively). RESULTS: Eighty-one subjects, 73 of whom also attended the 1-month follow-up visit, participated over 34 months. NIV tolerance after the first day of utilization predicted tolerance at 1 month (77.6% and 75.3% of subjects, respectively). Multivariate analysis disclosed 3 factors predicting good NIV tolerance: absence of airway secretions accumulation prior to NIV onset (odds ratio 11.5); normal bulbar function at initiation of NIV (odds ratio 8.5); and older age (weakly significant, odds ratio 1.1). CONCLUSION: Our study reveals 3 factors that are predictive of good NIV tolerance, in particular the absence of airway secretion accumulation, which should prompt NIV initiation before its appearance.

One-year experience with high-emergency lung transplantation in France.

BACKGROUND: The continuing significant number of patients who die while on a waiting list for lung transplantation (LTx) has led several countries to modify their lung allocation rules in recent years. France has implemented high-emergency allocation rules to allow patients at imminent risk of death to undergo priority transplantation within several days. The aim of this study was to report on the early (2-year) experience of high-emergency LTx (HELTx) in France. METHODS: From July 1, 2007, to June 30, 2008, 186 patients underwent LTx in France in nine centers. Among them, 32 patients (17.2%) underwent HELTx (19 with cystic fibrosis, 7 pulmonary fibrosis, and 6 other diagnoses). The reasons for HELTx were risk of invasive mechanical ventilation (n=20), invasive mechanical ventilation (n=8), and extracorporeal membrane oxygenation (n=4). RESULTS: The median time between being placed on the HELTx waiting list and LTx was 3 days (interquartile range: 1-8 days). Survival rates in the HELTx group were 90.5%, 71%, 64.5%, 55%, and 51.5% at 1, 3, 6, 12, and 24 months, respectively, which were significantly lower than for 154 patients who underwent regular, nonurgent LTx during the study period (88.5%, 83%, 79%, 77%, and 71%, respectively). CONCLUSIONS: Our data demonstrate that the new LTx allocation rules implemented in France since 2007 allow for rapid organ procurement for patients at imminent high risk of death. HELTx is feasible but yields poorer survival than elective LTx. Further studies are needed to assess implications of this organ allocation policy on the long run.
