Low-grade dysplasia in Barrett's esophagus: A problematic diagnosis / Displasia de bajo grado en el esófago de Barrett: un diagnóstico problemático

Although low-grade dysplasia (LGD) in Barrett's esophagus (BE) is a histopathological diagnosis based on different histological abnormalities, it is still problematic for different reasons. Patients without confirmed diagnosis of LGD undergo unnecessary and intensified follow-up where the risk of progression is low in the majority of cases. In contrast, the presence of confirmed LGD indicates a high risk of progression. In this article we try to address these reasons focusing on re-confirmation of LGD diagnosis, interobserver agreement, and persistent confirmed LGD. The progression risk of LGD to high-grade dysplasia and esophageal adenocarcinoma will also be reviewed. (AU)

Aunque la displasia de bajo grado (DBG) en el esófago de Barrett (EB) es un diagnóstico histopatológico basado en diferentes anomalías histológicas, este no deja de ser problemático por diferentes razones. Los pacientes sin diagnóstico confirmado de DBG se someten a un seguimiento innecesario e intensificado donde el riesgo de progresión es bajo en la mayoría de los casos. Por el contrario, la presencia de DBG confirmada indica un alto riesgo de progresión. En este artículo tratamos de abordar estas razones centrándonos en la reconfirmación del diagnóstico de la DBG, la concordancia entre observadores y la DBG confirmada y persistente. También se revisará el riesgo de progresión de la DBG a displasia de alto grado y adenocarcinoma esofágico. (AU)

Airway Complications after Lung Transplantation-A Contemporary Series of 400 Bronchial Anastomoses from a Single Center.

(1) Objective: To determine whether recent advances in lung transplantation (LT) have reduced the incidence and changed the risk factors for airway complications (AC). (2) Methods: Retrospective analysis of patients receiving a lung transplant between January 2007 and January 2019. An AC was defined as a bronchoscopic abnormality in the airway, either requiring or not requiring an endoscopic or surgical intervention. Both univariable and multivariable analyses were performed to identify risk factors for AC. (3) Results: 285 lung transplants (170 single and 115 bilateral lung transplants) were analysed, comprising 400 anastomoses at risk. A total of 50 anastomoses resulted in AC (12%). There were 14 anastomotic and 11 non-anastomotic stenoses, 4 dehiscences, and 3 malacias. Independent predictors for AC were: gender male (OR: 4.18; p = 0.002), cardiac comorbidities (OR: 2.74; p = 0.009), prolonged postoperative mechanical ventilation (OR: 2.5; p = 0.02), PaO2/FiO2 < 300 mmHg at 24 h post-LT (OR: 2.48; p = 0.01), graft infection (OR: 2.16; p = 0.05), and post-LT isolation of Aspergillus spp. (OR: 2.63; p = 0.03). (4) Conclusions: In spite of advances in lung transplantation practice, the risk factors, incidence, and lethality of AC after LT remains unchanged. Graft dysfunction, an infected environment, and the need of prolonged mechanical ventilation remain an Achilles heel for AC.

Using Interpretable Machine Learning to Identify Baseline Predictive Factors of Remission and Drug Durability in Crohn's Disease Patients on Ustekinumab.

Ustekinumab has shown efficacy in Crohn's Disease (CD) patients. To identify patient profiles of those who benefit the most from this treatment would help to position this drug in the therapeutic paradigm of CD and generate hypotheses for future trials. The objective of this analysis was to determine whether baseline patient characteristics are predictive of remission and the drug durability of ustekinumab, and whether its positioning with respect to prior use of biologics has a significant effect after correcting for disease severity and phenotype at baseline using interpretable machine learning. Patients' data from SUSTAIN, a retrospective multicenter single-arm cohort study, were used. Disease phenotype, baseline laboratory data, and prior treatment characteristics were documented. Clinical remission was defined as the Harvey Bradshaw Index ≤ 4 and was tracked longitudinally. Drug durability was defined as the time until a patient discontinued treatment. A total of 439 participants from 60 centers were included and a total of 20 baseline covariates considered. Less exposure to previous biologics had a positive effect on remission, even after controlling for baseline disease severity using a non-linear, additive, multivariable model. Additionally, age, body mass index, and fecal calprotectin at baseline were found to be statistically significant as independent negative risk factors for both remission and drug survival, with further risk factors identified for remission.

Long-Term Real-World Effectiveness and Safety of Ustekinumab in Crohn's Disease Patients: The SUSTAIN Study.

BACKGROUND: Large real-world-evidence studies are required to confirm the durability of response, effectiveness, and safety of ustekinumab in Crohn's disease (CD) patients in real-world clinical practice. METHODS: A retrospective, multicentre study was conducted in Spain in patients with active CD who had received ≥1 intravenous dose of ustekinumab for ≥6 months. Primary outcome was ustekinumab retention rate; secondary outcomes were to identify predictive factors for drug retention, short-term remission (week 16), loss of response and predictive factors for short-term efficacy and loss of response, and ustekinumab safety. RESULTS: A total of 463 patients were included. Mean baseline Harvey-Bradshaw Index was 8.4. A total of 447 (96.5%) patients had received prior biologic therapy, 141 (30.5%) of whom had received ≥3 agents. In addition, 35.2% received concomitant immunosuppressants, and 47.1% had ≥1 abdominal surgery. At week 16, 56% had remission, 70% had response, and 26.1% required dose escalation or intensification; of these, 24.8% did not subsequently reduce dose. After a median follow-up of 15 months, 356 (77%) patients continued treatment. The incidence rate of ustekinumab discontinuation was 18% per patient-year of follow-up. Previous intestinal surgery and concomitant steroid treatment were associated with higher risk of ustekinumab discontinuation, while a maintenance schedule every 12 weeks had a lower risk; neither concomitant immunosuppressants nor the number of previous biologics were associated with ustekinumab discontinuation risk. Fifty adverse events were reported in 39 (8.4%) patients; 4 of them were severe (2 infections, 1 malignancy, and 1 fever). CONCLUSIONS: Ustekinumab is effective and safe as short- and long-term treatment in a refractory cohort of CD patients in real-world clinical practice.

This large retrospective study demonstrated the short- and long-term effectiveness and safety of ustekinumab in patients with Crohn's disease in real-world clinical practice, including those with refractory disease.

Lung Transplantation in a Young Patient With Pulmonary Artery Hypertension After Arterial Switch Operation: A Case Report.

Pulmonary hypertension after surgical correction of D-transposition of the great vessels is a rare but serious complication. Lung transplantation may be the only option when treatment with vasodilators is insufficient. We present the case of a young male patient with a history of arterial switch in neonatal period who undergoes double lung transplantation owing to late pulmonary hypertension.

Relationship Among Radiological Measurements of Anterior Mediastinal Fat and Outcomes of Lung Transplantation in Fibrotic Patients / Relación entre las medidas radiológicas de la grasa mediastínica anterior y los resultados del trasplante de pulmón en pacientes con fibrosis

OBJECTIVE: Lung transplantation (LT) for pulmonary fibrosis is related to higher mortality than other transplant indications. We aim to assess whether the amount of anterior mediastinal fat (AMF) was associated to early and long-term outcomes in fibrotic patients undergoing LT. METHODS: Retrospective analysis of 92 consecutive single lung transplants (SLT) for pulmonary fibrosis over a 10-year period. AMF dimensions were measured on preoperative CT-scan: anteroposterior axis (AP), transverse axis (T), and height (H). AMF volumes (V) were calculated by the formula: AP×T×H×3.14/6. According to the radiological AMF dimensions, patients were distributed into two groups: low-AMF (V < 20 cm3) and high-AMF (V > 20 cm3), and early and long-term outcomes were compared by univariable and multivariable analyses. RESULTS: There were 92 SLT: 73M/19F, 53 ± 11 [14-68] years old. 30-Day mortality (low-AMF vs. high-AMF): 5 (5.4%) vs. 15 (16.3%), p = 0.014. Patients developing primary graft dysfunction within 72 h post-transplant, and those dying within 30 days post-transplant presented higher AMF volumes: 21.1 ± 19.8 vs. 43.3 ± 24.7 cm3 (p = 0.03) and 24.4 ± 24.2 vs. 56.9 ± 63.6 cm3 (p < 0.01) respectively. Overall survival (low-AMF vs. high-AMF) (1, 3, and 5 years): 85%, 81%, 78% vs. 55%, 40%, 33% (p < 0.001). Factors predicting 30-day mortality were: BMI (HR = 0.77, p = 0.011), AMF volume (HR = 1.04, p = 0.018), CPB (HR = 1.42, p = 0.002), ischaemic time (HR = 1.01, p = 0.009). Factors predicting survival were: AMF volume (HR=1.02, p < 0.001), CPB (HR = 3.17, p = 0.003), ischaemic time (HR = 1.01, p = 0.001). CONCLUSION: Preoperative radiological assessment of mediastinal fat dimensions and volumes may be a useful tool to identify fibrotic patients at higher risk of mortality after single lung transplantation

OBJETIVO: El trasplante de pulmón (TP) para el tratamiento de la fibrosis pulmonar está relacionado con una mayor mortalidad que otras indicaciones de trasplante. Nuestro objetivo es evaluar si la cantidad de grasa mediastínica anterior (GMA) se asoció a los diferentes resultados tempranos y a largo plazo en pacientes con fibrosis a los que se les realizó un TP. MÉTODOS: Análisis retrospectivo de 92 trasplantes de pulmón unilaterales (TPU) consecutivos para el tratamiento de la fibrosis pulmonar durante un período de 10 años. Se midieron las dimensiones de la GMA en la TC preoperatoria: eje anteroposterior (AP), eje transversal (T) y altura (A). Los volúmenes de GMA (V) se calcularon mediante la fórmula: AP×T×A×3,14/6. Según las dimensiones radiológicas de la GMA, los pacientes se distribuyeron en 2 grupos: GMA baja (V < 20 cm3) y GMA alta (V > 20 cm3), y los resultados tempranos y a largo plazo se compararon mediante análisis univariables y multivariables. RESULTADOS: Se realizaron 92 TPU: 73V/19M, 53 ± 11 (14-68) años. Mortalidad a 30 días (GMA baja frente a GMA alta): 5 (5,4%) frente a 15 (16,3%); p = 0,014. Los pacientes que desarrollaron disfunción precoz del injerto dentro de las 72 h posteriores al trasplante, y los que murieron dentro de los 30 días posteriores al trasplante presentaron mayores volúmenes de GMA: 21,1±19,8 frente a 43,3 ± 24,7 cm3 (p = 0,03) y 24,4 ± 24,2 frente a 56,9 ± 63,6 cm3 (p < 0,01), respectivamente. Supervivencia global (GMA baja frente a GMA alta) (a los 1, 3 y 5 años): 85, 81 y 78% frente al 55, 40 y 33% (p < 0,001), respectivamente. Los factores que predijeron la mortalidad a los 30 días fueron: IMC (HR = 0,77; p = 0,011), volumen de la GMA (HR = 1,04; p = 0,018), CEC (HR = 1,42; p = 0,002), tiempo de isquemia (HR=1,01; p = 0,009). Los factores que predijeron la supervivencia fueron: volumen GMA (HR = 1,02; p < 0,001), CEC (HR = 3,17; p = 0,003) y tiempo de isquemia (HR = 1,01; p = 0,001)

A retrospective and prospective 12-month observational study of the socioeconomic burden of moderate to severe irritable bowel syndrome with constipation in Spain / Estudio observacional, retrospectivo y prospectivo a 12 meses del coste socioeconómico del síndrome del intestino irritable moderado a grave con estreñimiento en España

Introduction: The socioeconomic burden of irritable bowel syndrome with constipation (IBS-C) has never been formally assessed in Spain. Patients and methods: This 12-month (6-month retrospective and prospective periods) observational, multicentre study assessed the burden of moderate-to-severe IBS-C in Spain. Patients were included if they had been diagnosed with IBS-C (Rome III criteria) within the last 5 years and had moderate-to-severe IBS-C (IBS Symptom Severity Scale score [IBS-SSS] ≥175) at inclusion. The primary objective was to assess the direct cost to the Spanish healthcare system (HS). Results: A total of 112 patients were included, 64 (57%) of which had severe IBS-C at inclusion. At baseline, 89 (80%) patients reported abdominal pain and distention. Patient quality of life (QoL), measured by the IBS-C QoL and EQ-5D instruments, was found to be impaired with a mean score of 59 and 57 (0-100, worst-best), respectively. Over the 6-month prospective period the mean IBS-C severity, measured using the IBS-SSS showed some improvement (315-234 [0-500, best-worst]). During the year, 89 (80%) patients used prescription drugs for IBS-C, with laxatives being the most frequently prescribed (n=70; 63%). The direct cost to the HS was €1067, and to the patient was €568 per year. The total direct cost for moderate-to-severe IBS-C was €1635. Discussion: The majority of patients reported continuous IBS-C symptoms despite that 80% were taking medication to treat their IBS-C. Overall healthcare resource use and direct costs were asymmetric, with a small group of patients consuming the majority of resources

Introducción: El coste socioeconómico del síndrome del intestino irritable con estreñimiento (SII-E) no ha sido evaluado formalmente en España. Pacientes y métodos: Este estudio observacional, multicéntrico a 12 meses (periodos retrospectivo y prospectivo de 6 meses) evaluó el coste del SII-E moderado-grave en España. Se incluyeron pacientes diagnosticados con SII-E (criterios Roma III) en los últimos 5 años y SII-E moderado-grave (puntuación IBS-Symptom Severity Scale [IBS-SSS]≥175) en la inclusión. El objetivo principal fue evaluar el coste directo para el sistema sanitario (SS) español. Resultados: Se incluyeron un total de 112 pacientes, 64 (57%) de los cuales presentaban SII-E grave en la inclusión. En el momento basal, 89 (80%) pacientes presentaron dolor y distensión abdominal. La calidad de vida del paciente, medida mediante los instrumentos IBS-C QoL y EQ-5D, estaba deteriorada, con una puntuación de 59 y 57 (0-100, peor-mejor), respectivamente. En el periodo prospectivo la gravedad media del SII-E, medida mediante IBS-SSS, mostró alguna mejoría (315 a 234 [0-500, mejor-peor]). Durante el periodo a studio, 89 (80%) pacientes usaron fármacos prescritos para el SII-E, principalmente laxantes (n=70; 63%). El coste directo anual fue de 1.067€ y 568€ para el SS y el paciente, respectivamente. El coste total directo del SII-E moderado-grave fue de 1.635€. Discusión: La mayoría de pacientes presentaron síntomas continuos del SII-E pese a que el 80% tomaban medicación específica. El uso de recursos sanitarios y los costes directos globales fueron asimétricos, con un pequeño grupo de pacientes consumiendo la mayoría de los recursos

Factores pronósticos de mortalidad en la cirrosis hepática tras un primer episodio de peritonitis bacteriana espontánea. Estudio multicéntrico / Prognostic factors of liver cirrhosis mortality after a first episode of spontaneous bacterial peritonitis. A multicenter study

Introducción: la peritonitis bacteriana espontánea es una complicación infecciosa con impacto negativo sobre la supervivencia de los pacientes con cirrosis. Objetivo: analizar la supervivencia a corto y largo plazo después de un primer episodio de peritonitis bacteriana espontánea y los factores pronósticos asociados. Material y métodos: estudio multicéntrico retrospectivo que incluyó a los pacientes ingresados por peritonitis bacteriana espontánea entre 2008 y 2013. Las variables independientes relacionadas con la mortalidad se analizaron mediante regresión logística. Se analizó el poder pronóstico de los índices Child Pugh, MELD y Charlson mediante curva de ROC. Resultados: fueron incluidos 159 pacientes. El 72% fueron hombres con una edad media de 63,5 años y con una puntuación MELD de 19 (DE ± 9,5). La mortalidad a los 30 días, 90 días, al año y a los dos años fue del 21%, 31%, 55% y 69%, respectivamente. La encefalopatía hepática (p = 0,008; OR 3,5; IC 95% 1,4-8,8) y la función renal (p = 0,026; OR 2,7; IC 95% 1,13-16,7) fueron factores independientes de mortalidad a corto y largo plazo. El MELD fue un buen indicador de supervivencia a corto y largo plazo (área bajo la curva [AUC] 0,7: IC 95% 1,02-1,4). El índice de Charlson se relacionó con la mortalidad a largo plazo (AUC 0,68: IC 95% 0,6-0,77). Conclusiones: en la peritonitis bacteriana espontánea la mortalidad a corto y largo plazo sigue siendo elevada. Los principales factores pronósticos de mortalidad son el deterioro de la función hepática y renal. El MELD y el índice de Charlson son unos buenos indicadores de supervivencia (AU)

Introduction: Spontaneous bacterial peritonitis is an infectious complication with a negative impact on survival of patients with cirrhosis. Objective: To analyze the short- and long-term survival after a first episode of bacterial peritonitis and the associated prognostic factors. Patients and methods: This was a retrospective, multicenter study of patients admitted to hospital for spontaneous bacterial peritonitis between 2008 and 2013. Independent variables related to mortality were analyzed by logistic regression. The prognostic power of the Child Pugh Score, the Model for End-Stage Liver Disease (MELD) and the Charlson index was analyzed by ROC curve. Results: A total of 159 patients were enrolled, 72% were males with a mean age of 63.5 years and a mean MELD score of 19 (SD ± 9.5). Mortality at 30 and 90 days and one and two years was 21%, 31%, 55% and 69%, respectively. Hepatic encephalopathy (p = 0.008, OR 3.5, 95% CI 1.4-8.8) and kidney function (p = 0.026, OR 2.7, 95% CI 1.13-16.7) were independent factors for short- and long-term mortality. MELD was a good marker of short- and long-term survival (area under the curve [AUC] 0.7: 95% CI 1.02-1.4). The Charlson index was related to long-term mortality (AUC 0.68: 95% CI 0.6-0.77). Conclusions: Short- and long-term mortality of spontaneous bacterial peritonitis is still high. The main prognostic factors for mortality are impairment of liver and kidney function. MELD and the Charlson index are good markers of survival (AU)

Prevalence of Malnutrition and Nutritional Characteristics of Patients With Inflammatory Bowel Disease.

BACKGROUND AND AIMS: This study sought to determine the prevalence of malnutrition in patients with inflammatory bowel disease, to analyse the dietary beliefs and behaviours of these patients, to study their body composition, to evaluate their muscular strength and to identify the factors associated with malnutrition in these patients. METHODS: This was a prospective, multicentre study. Crohn's disease and ulcerative colitis patients from 30 Spanish centres, from the outpatient clinics, were included. A questionnaire of 11 items was applied to obtain data from patients' dietary behaviour and beliefs. Patients who accepted were evaluated to assess their nutritional status using Subjective Global Assessment and body mass index. Body composition was evaluated through bioelectrical impedance. RESULTS: A total of 1271 patients were included [51% women, median age 45 years, 60% Crohn's disease]. Of these, 333 patients underwent the nutritional evaluation. A total of 77% of patients declared that they avoided some foods to prevent disease relapse. Eighty-six per cent of patients avoided some foods when they had disease activity because of fear of worsening the flare. Sixty-seven per cent of patients modified their dietary habits after disease diagnosis. The prevalence of malnutrition was 16% [95% confidence interval = 12-20%]. In the multivariate analysis, history of abdominal surgery, active disease and avoidance of some foods during flares were associated with higher risk of malnutrition. CONCLUSIONS: The prevalence of malnutrition in inflammatory bowel disease patients was high. We identified some predictive factors of malnutrition. Most of the patients had self-imposed food restrictions, based on their beliefs.

Lung transplantation for cystic fibrosis: differential characteristics and outcomes between children and adults.

OBJECTIVES: The survival benefit of lung transplantation (LTx) for cystic fibrosis (CF) patients is well demonstrated. We aim to compare children and adult CF recipients to assess whether there are differences in survival and clinical outcomes, and to identify risk factors for mortality. METHODS: A retrospective analysis of 442 consecutive LTx performed at our institution in a 20-year period was conducted. CF patients were distributed into two groups: children (age <18 years) and adults (age ≥18 years). Donor and recipient general demographic data, perioperative and postoperative factors including 30-day mortality, survival, primary graft dysfunction (PGD), complications, acute rejection (AR) and chronic lung allograft dysfunction (CLAD) were analysed and compared between groups. Univariable, Kaplan-Meier and Cox regression analyses were performed. RESULTS: The study group included 120 consecutive CF patients: 50 children (13 ± 3 years) and 70 adults (25 ± 6 years) undergoing 111 bilateral, 4 lobar, 4 combined and 1 unilateral LTx. Comparative analysis (children versus adults): survival (overall; 5, 10 and 15 years) 57, 45, 35% vs 67, 55, 43% (P = 0.32); survival (1-year survivors; 5, 10 and 15 years): 75, 64, 46% vs 90, 75, 59% (P = 0.09); 30-day mortality: 14 vs 16% (P = 0.27); urgent LTx: 32 vs 17% (P = 0.04); use of cardiopulmonary bypass (CPB): 56 vs 28% (P = 0.002); intensive care unit stay: 20 ± 19 vs 10 ± 9 days (P = 0.006); AR episodes (n): 1.4 ± 0.7 vs 1.2 ± 0.8 (P = 0.004). Incidence of PGD and freedom from CLAD did not differ between groups. Predictors of mortality were: use of CPB (HR 3.12; 95% CI 1.33-7.35; P < 0.01), post-transplant diabetes mellitus (HR 2.49; 95% CI 1.13-5.43; P = 0.02) and pneumonia episodes within the first month post-transplant (HR 2.82; 95% CI 1.27-6.29; P = 0.01). CONCLUSION: Paediatric CF patients usually present with poorer pre-transplant status, require CPB more frequently and have a higher incidence of post-LTx diabetes and infections. This might explain the trend towards a better long-term survival observed in adult CF patients.

Patients with recently-diagnosed adult celiac disease were evaluated with the Gastrointestinal Symptom rating Scale (GSRS) and Psychological General Well-Being Index (PGWBI) to evaluate their psychological alterations, the association between any alterations and gastrointestinal symptoms, and their outcome after starting a gluten-free diet. The patients underwent nutritional assessment and then started a gluten-free diet; they were reassessed 6 months later. Quantitative variables are expressed as the median and 25th-75th percentiles. Results: We included 21 patients, 17 women and 4 mena, with a mean age of 43 years (31-47). The results of histological analysis were compatible with Marsh I lesions in 6 patients, Marsh IIIa in 6 and Marsh IIIb in 9. At baseline, 8 patients showed severe psychological distress, 4 showed moderate distress and 9 showed no distress. The GSRS score was 34 (17-43) and the PGWBI was 64 (48-87), with a significant correlation between the 2 indexes (rho = -.58, P = .006). At 6 months, 3 patients had severe psychological distress, 5 had moderate distress, 9 showed no distress and 4 showed psychological well-being. The GSRS score at 6 months was 13 (8-17) and the PGWBI was 83 (68-95) (P < .05 compared with baseline data for the 3 indicators). The 6 axes of the PGWBI showed significant improvement. At 6 months, no correlation was found between the GSRS and PGWBI. Conclusions: Patients with celiac disease have psychological alterations whose intensity is relted to gastrointestinal symptoms. These symptoms improve after the start of a gluten-free diet

UNLABELLED: Patients with recently-diagnosed adult celiac disease were evaluated with the Gastrointestinal Symptom rating Scale (GSRS) and Psychological General Well-Being Index (PGWBI) to evaluate their psychological alterations, the association between any alterations and gastrointestinal symptoms, and their outcome after starting a gluten-free diet. The patients underwent nutritional assessment and then started a gluten-free diet; they were reassessed 6 months later. Quantitative variables are expressed as the median and 25th-75th percentiles. RESULTS: We included 21 patients, 17 women and 4 mena, with a mean age of 43 years (31-47). The results of histological analysis were compatible with Marsh I lesions in 6 patients, Marsh IIIa in 6 and Marsh IIIb in 9. At baseline, 8 patients showed severe psychological distress, 4 showed moderate distress and 9 showed no distress. The GSRS score was 34 (17-43) and the PGWBI was 64 (48-87), with a significant correlation between the 2 indexes (rho=-.58, P=.006). At 6 months, 3 patients had severe psychological distress, 5 had moderate distress, 9 showed no distress and 4 showed psychological well-being. The GSRS score at 6 months was 13 (8-17) and the PGWBI was 83 (68-95) (P<.05 compared with baseline data for the 3 indicators). The 6 axes of the PGWBI showed significant improvement. At 6 months, no correlation was found between the GSRS and PGWBI. CONCLUSIONS: Patients with celiac disease have psychological alterations whose intensity is related to gastrointestinal symptoms. These symptoms improve after the start of a gluten-free diet.

Extended recipients but not extended donors are associated with poor outcomes following lung transplantation.

OBJECTIVES: Extended donors (EDs) are safely used to increase the donor pool in lung transplantation (LT), but their influence in critically ill patients (extended recipients [ERs]) remains controversial. We compared LT outcomes matching optimal donors (ODs) or EDs with optimal recipients (ORs) or ERs. METHODS: Three hundred and sixty-five LTs were reviewed. ED criteria: age >55, PaO2/FiO2 < 350 mmHg, pulmonary infiltrates/purulent secretions and ischaemic times >6 h (single LT [SLT]) and >9 h (double LT [DLT]). ER criteria: pulmonary fibrosis or pulmonary hypertension, pretransplant intubation, age >60 years and bypass >2 h. Four groups were created: Group 1 (OD/OR), Group 2 (OD/ER), Group 3 (ED/OR) and Group 4 (ED/ER). Thirty-day mortality, primary graft dysfunction (PGD), onset of bronchiolitis obliterans syndrome (BOS), long-term survival and other transplant outcomes were compared between OD and ED, OR and ER and among the four groups of study. RESULTS: There were 151 SLTs and 214 DLTs. Donors: OD (n = 229) vs ED (n = 136); PGD 8 vs 10% (P = 0.43); 30-day mortality 19 vs 20% (P = 0.53) and survival (1, 5, 10 and 15 years) 67, 47, 34, 26 vs 69, 53, 46 and 29% (P = 0.33). Recipients: OR (n = 182) vs ER (n = 183); PGD 7 vs 10% (P = 0.10); 30-day mortality 15 vs 23% (P = 0.04) and survival (1, 5, 10 and 15 years): 73, 57, 46, 30 vs 61, 42, 29 and 23% (P = 0.002). Four donor/recipient (D/R) groups: Group 1 (n = 122), Group 2 (n = 106), Group 3 (n = 61), Group 4 (n = 76); PGD 10, 6, 3 and 16% (P = 0.05); 30-day mortality 13, 26, 19 and 20%, respectively (P = 0.13); survival (1, 5, 10 and 15 years) 74, 55, 44 and 35% (Group 1), 55, 39, 22 and 16% (Group 2), 70, 59, 48 and 26% (Group 3) and 68, 47, 37 and 22% (Group 4) (P = 0.004). No differences in the onset of BOS were observed among the four study groups. CONCLUSIONS: LT in critically ill recipients is associated with poor early and long-term outcomes, irrespective of the quality of the donor and length of ischaemic times.
