Is Night Surgery a Nightmare for Lung Transplantation?

Night work is frequently associated with sleep deprivation and is associated with greater surgical and medical complications. Lung transplantation (LT) is carried out both at night and during the day and involves many medical healthcare workers. The goal of the study was to compare morbidity and mortality between LT recipients according to LT operative time. We performed a retrospective, observational, single-center study. When the procedure started between 6 AM and 6 PM, the patient was allocated to the Daytime group. If the procedure started between 6 PM and 6 AM, the patient was allocated to the Nighttime group. Between January 2015 and December 2020, 253 patients were included. A total of 168 (66%) patients were classified into the Day group, and 85 (34%) patients were classified into the Night group. Lung Donors' general characteristics were similar between the groups. The 90-day and one-year mortality rates were similar between the groups (90-days: n = 13 (15%) vs. n = 26 (15%), p = 0.970; 1 year: n = 18 (21%) vs. n = 42 (25%), p = 0.499). Daytime LT was associated with more one-year airway dehiscence (n = 36 (21%) vs. n = 6 (7.1%), p = 0.004). In conclusion, among patients who underwent LT, there was no significant association between operative time and survival.

Effect of antifibrotic agents on postoperative complications after lung transplantation for idiopathic pulmonary fibrosis.

BACKGROUND: Antifibrotic agents (AFAs) are now standard-of-care for idiopathic pulmonary fibrosis (IPF). Concerns have arisen about the safety of these drugs in patients undergoing lung transplantation (LTx). METHODS: We performed a multi-centre, nationwide, retrospective, observational study of French IPF patients undergoing LTx between 2011 and 2018 to determine whether maintaining AFAs in the peri-operative period leads to increased bronchial anastomoses issues, delay in skin healing and haemorrhagic complications. We compared the incidence of post-operative complications and the survival of patients according to AFA exposure. RESULTS: Among 205 patients who underwent LTx for IPF during the study period, 58 (28%) had received AFAs within 4 weeks before LTx (AFA group): pirfenidone in 37 (18.0%) and nintedanib in 21 (10.2%). The median duration of AFA treatment before LTx was 13.8 (5.6-24) months. The AFA and control groups did not significantly differ in airway, bleeding or skin healing complications (p = 0.91, p = 0.12 and p = 0.70, respectively). Primary graft dysfunction was less frequent in the AFA than control group (26% vs. 43%, p = 0.02), and the 90-day mortality was lower (7% vs. 18%, p = 0.046). CONCLUSIONS: AFA therapy did not increase airway, bleeding or wound post-operative complications after LTx and could be associated with reduced rates of primary graft dysfunction and 90-day mortality.

Low HDL-Cholesterol Concentrations in Lung Transplant Candidates are Strongly Associated With One-Year Mortality After Lung Transplantation.

High-density lipoproteins (HDLs), whose main role is the reverse transport of cholesterol, also have pleiotropic anti-inflammatory, antioxidant, anti-apoptotic and anti-infectious properties. During sepsis, HDL cholesterol (HDL-C) concentration is low, HDL particle functionality is altered, and these modifications are correlated with poor outcomes. Based on the protective effects of HDL, we hypothesized that HDL-C levels could be associated with lung transplantation (LT) outcome. We thus looked for an association between basal HDL-C concentration and one-year mortality after LT. In this single-center prospective study including consecutive LTs from 2015 to 2020, 215 patients were included, essentially pulmonary fibrosis (47%) and chronic obstructive pulmonary disease (COPD) (38%) patients. Mortality rate at one-year was 23%. Basal HDL-C concentration stratified nonsurvivors to survivors at one-year (HDL-C = 1.26 [1.12-1.62] mmol/L vs. HDL-C = 1.55 [1.22-1.97] mmol/L, p = 0.006). Multivariate analysis confirmed that HDL-C concentration during the pretransplant assessment period was the only variable inversely associated with mortality. Moreover, mortality at one-year in patients with HDL-C concentrations ≤1.45 mmol/L was significantly higher (log-rank test, p = 0.00085). In conclusion, low basal HDL-C concentrations in candidates for LT are strongly associated with mortality after LT. To better understand this association, further studies in this field are essential and, in particular, a better characterization of HDL particles seems necessary.

Impact of Culture-Positive Preservation Fluid on Early Morbidity and Mortality After Lung Transplantation.

The prevalence, risk factors and outcomes associated with culture-positive preservation fluid (PF) after lung transplantation (LT) are unknown. From January 2015 to December 2020, the microbiologic analyses of PF used to store the cold ischaemia-placed lung graft(s) of 271 lung transplant patients were retrospectively studied. Culture-positive PF was defined as the growth of any microorganism. Eighty-three (30.6%) patients were transplanted with lung grafts stored in a culture-positive PF. One-third of culture-positive PF were polymicrobial. Staphylococcus aureus and Escherichia coli were the most frequently isolated microorganisms. No risk factors for culture-positive PF based on donor characteristics were identified. Forty (40/83; 48.2%) patients had postoperative pneumonia on Day 0 and 2 (2/83; 2.4%) patients had pleural empyema with at least one identical bacteria isolated in culture-positive PF. The 30-day survival rate was lower for patients with culture-positive PF compared with patients with culture-negative PF (85.5% vs. 94.7%, p = 0.01). Culture-positive PF has a high prevalence and may decrease lung transplant recipient survival. Further studies are required to confirm these results and improve understanding of the pathogenesis of culture-positive PF and their management.

Ultrasonography in thoracic and abdominal stab wound injury: results from the FETTHA study.

BACKGROUND: While the role of Extended Focused Assessment with Sonography in Trauma (eFAST) is well defined in the management of severe blunt trauma, its performance in injuries caused by stab wounds has been poorly assessed. METHODS: Prospective single centre study which included all patients with stab wounds to the thorax or abdomen between December 2016 and December 2018. All patients underwent initial investigation with both eFAST and CT scan, except in cases of haemodynamic or respiratory instability, and in cases with a positive diagnosis by eFAST in which case surgery without CT scan was performed. RESULTS: Of the 200 consecutive patients included, 14 unstable patients underwent surgery immediately after eFAST. In these 14 patients, 9 had cardiac tamponade identified by eFAST and all were confirmed by surgery. In the remaining 186 patients, the median time between eFAST and CT scan was 30 min (IQR 20-49 min). Test characteristics (including 95% CI) for eFAST compared with reference standard of CT scan for detecting pneumothorax were as follows: sensitivity 77% (54%-92%), specificity 93% (90%-97%), positive predictive value (PPV) 60% (49%-83%), negative predictive value (NPV) 97% (93%-99%). Test characteristics (including 95% CI) for eFAST compared with CT scan for detecting haemothorax were as follows: sensitivity 97% (74%-99%), specificity 96% (92%-98%), PPV 83% (63%-93%) and NPV 99% (96%-100%). Finally, test characteristics (including 95% CI) for eFAST compared with CT scan for detecting haemoperitoneum were as follows: sensitivity 75% (35%-97%), specificity 97% (93%-99%), PPV 55% (23%-83%) and NPV 99% (96%-99%). CONCLUSIONS: In patients admitted with stab wounds to the torso, eFAST was not sensitive enough to diagnose pneumothorax and haemoperitoneum, but performed better in the detection of cardiac tamponade and haemothorax than the other injuries. More robust multicentre studies are needed to better define the role of eFAST in this specific population.

Plasma Apolipoprotein Concentrations Are Highly Altered in Severe Intensive Care Unit COVID-19 Patients: Preliminary Results from the LIPICOR Cohort Study.

SARS-CoV-2 infection goes beyond acute pneumonia, as it also impacts lipid metabolism. Decreased HDL-C and LDL-C levels have been reported in patients with COVID-19. The lipid profile is a less robust biochemical marker than apolipoproteins, components of lipoproteins. However, the association of apolipoprotein levels during COVID-19 is not well described and understood. The objective of our study is to measure plasma levels of 14 apolipoproteins in patients with COVID-19 and to evaluate the relationships between apolipoprotein levels, severity factors and patient outcomes. From November to March 2021, 44 patients were recruited on admission to the intensive care unit because of COVID-19. Fourteen apolipoproteins and LCAT were measured by LC-MS/MS in plasma of 44 COVID-19 patients on admission to the ICU and 44 healthy control subjects. Absolute apolipoprotein concentrations were compared between COVID-19 patients and controls. Plasma apolipoproteins (Apo) A (I, II, IV), C(I, II), D, H, J and M and LCAT were lower in COVID-19 patients, whereas Apo E was higher. COVID-19 severity factors such as PaO2/FiO2 ratio, SO-FA score and CRP were correlated with certain apolipoproteins. Lower Apo B100 and LCAT levels were observed in non-survivors of COVID-19 versus survivors. To conclude, in this study, lipid and apolipoprotein profiles are altered in COVID-19 patients. Low Apo B100 and LCAT levels may be predictive of non-survival in COVID-19 patients.

Impact of prior antibiotic therapy on severe necrotizing soft-tissue infections in ICU patients: results from a French retrospective and observational study.

Necrotizing soft-tissue infection (NSTI) is a life-threatening pathology that often requires management in intensive care unit (ICU). Therapies consist of early diagnosis, adequate surgical source control, and antimicrobial therapy. Whereas guidelines underline the need for appropriate routine microbiological cultures before starting antimicrobial therapy in patients with suspected sepsis or septic shock, delaying adequate therapy also strongly increases mortality. The aim of the present study was to compare the characteristics and outcomes of patients hospitalized in ICU for NSTI according to their antimicrobial therapy exposure > 24 h before surgery (called the exposed group) or not (called the unexposed group) before surgical microbiological sampling. We retrospectively included 100 consecutive patients admitted for severe NSTI. The exposed group consisted of 23(23%) patients, while 77(77%) patients belonged to the unexposed group. The demographic and underlying disease conditions were similar between the two groups. Microbiological cultures of surgical samples were positive in 84 patients and negative in 16 patients, including 3/23 (13%) patients and 13/77 (17%) patients in the exposed and unexposed groups, respectively (p = 0.70). The distribution of microorganisms was comparable between the two groups. The main antimicrobial regimens for empiric therapy were also similar, and the proportions of adequacy were comparable (n = 60 (84.5%) in the unexposed group vs. n = 19 (86.4%) in the exposed group, p = 0.482). ICU and hospital lengths of stay and mortality rates were similar between the two groups. In conclusion, in a population of severe ICU NSTI patients, antibiotic exposure before sampling did not impact either culture sample positivity or microbiological findings.

Favorable, arduous or fatal postoperative pathway within 90 days of lung transplantation.

INTRODUCTION: The maximum gain in quality of life after lung transplantation (LT) is expected between six months and one year after LT, as the occurrence of chronic lung allograft dysfunction may mask the beneficial effects beyond one year. Thus, the postoperative period could be the cornerstone of graft success. We sought to describe the factors present before postoperative admission to the ICU and associated with favorable, arduous or fatal pathway within 90 days of LT. MATERIALS AND METHODS: We conducted a retrospective single-center study between January 2015 and December 2020. Using multinomial regression, we assessed the demographic, preoperative and intraoperative characteristics of patients associated with favorable (duration of postoperative mechanical ventilation < 3 days and alive at Day 90), arduous (duration of postoperative mechanical ventilation ≥ 3 days and alive at Day 90) or fatal (dead at Day 90) pathway within 90 days of LT. RESULTS: A total of 269 lung transplant patients were analyzed. Maximum graft cold ischemic time ≥ 6 h and intraoperative blood transfusion ≥ 3 packed red blood cells were associated with arduous and fatal pathway at Day 90, whereas intraoperative ECMO was strongly associated with fatal pathway. CONCLUSION: No patient demographics influenced the postoperative pathway at Day 90. Only extrinsic factors involving graft ischemia time, intraoperative transfusion, and intraoperative ECMO determined early postoperative pathway.

ECMO support as a bridge to lung transplantation is an independent risk factor for bronchial anastomotic dehiscence.

BACKGROUND: Airway complications are frequent after lung transplantation (LT), as they affect up to 23% of recipients. The implication of perioperative extracorporeal membrane oxygenation (ECMO) support and haemodynamic instability has never been specifically assessed. The first aim of this study was to explore the impact of perioperative ECMO support on bronchial anastomotic dehiscence (BAD) at Day 90 after LT. METHODS: This prospective observational monocentric study analysed BAD in all consecutive patients who underwent LT in the Bichat Claude Bernard Hospital, Paris, France, between January 2016 and May 2019. BAD visible on bronchial endoscopy and/or tomodensitometry was recorded. A univariate analysis was performed (Fisher's exacts and Mann-Whitney tests), followed by a multivariate analysis to assess independent risk factors for BAD during the first 90 days after LT (p < 0.05 as significant). The Paris North Hospitals Institutional Review Board approved the study. RESULTS: A total of 156 patients were analysed. BAD was observed in the first 90 days in 42 (27%) patients and was the main cause of death in 22 (14%) patients. BAD occurred during the first month after surgery in 34/42 (81%) patients. ECMO support was used as a bridge to LT, during and after surgery in 9 (6%), 117 (75%) and 40 (27%) patients, respectively. On multivariate analysis, ECMO as a bridge to LT (p = 0.04) and septic shock (p = 0.01) were independent risk factors for BAD. CONCLUSION: ECMO as a bridge to LT is an independent risk factor for BAD during the first 90 days after surgery. Close monitoring of bronchial conditions must be performed in these high-risk recipients.

Temporary ICUs during the COVID-19 pandemic first wave: description of the cohort at a French centre.

BACKGROUND: During the COVID-19 first wave in France, the capacity of intensive care unit (ICU) beds almost doubled, mainly because of the opening of temporary ICUs with staff and equipment from anaesthesia. OBJECTIVES: We aim to investigate if the initial management in temporary ICU is associated with a change in ICU mortality and short-term prognosis. DESIGN: Retrospective single-centre cohort study. SETTING: Surgical ICU of the Bichat Claude Bernard University Hospital during the COVID-19 "first wave" (from 18 March to 10 April 2020). PATIENTS: All consecutive patients older than 18 years of age with laboratory-confirmed SARS-CoV-2 infection and/or typical radiological patterns were included during their first stay in the ICU for COVID-19. INTERVENTION: Patients were admitted to a temporary ICU if no room was available in the classical ICU and if they needed invasive mechanical ventilation but no renal replacement therapy or Extracorporeal Membrane Oxygenation (ECMO) in the short term. The temporary ICUs were managed by mixed teams (from the ICU and anaesthesiology departments) following a common protocol and staff meetings. MAIN OUTCOME MEASURE: ICU mortality RESULTS: Among the 59 patients admitted, 37 (62.7%) patients had initial management in the temporary ICU. They had the same characteristics on admission and the same medical management as patients admitted to the classical ICU. ICU mortality was similar in the 2 groups (32.4% in temporary ICUs versus 40.9% in classical ICUs; p=0.58). SAPS-II and ECMO use were associated with mortality in multivariate analysis but not admission to the temporary ICU. CONCLUSION: In an overload context of the ICU of a geographical area, our temporary ICU model allowed access to intensive care for all patients requiring it without endangering them.

Blood transfusion of the donor is associated with stage 3 primary graft dysfunction after lung transplantation.

BACKGROUND: The first aim of this study was to assess the association between stage 3 PGD and pre-donation blood transfusion of the donor. The secondary objectives were to assess the epidemiology of donor transfusion and the outcome of LT recipients according to donor transfusion status and massive donor transfusion status. METHODS: This was an observational, prospective, single-center study. The results are expressed as absolute numbers, percentages, medians, and interquartile ranges. Statistical analyses were performed using Chi squared, Fischer's exact tests, and Mann-Whitney U tests (P < .05 was considered significant). A multivariate analysis was performed. RESULTS: Between January 2016 and February 2019, 147 patients were included in the analysis. PGD was observed in 79 (54%) patients, 45 (31%) of whom had stage 3 PGD. Pre-donation blood transfusion was administered in 48 (33%) donors (median of 3[1-9] packed red cells (PRCs)). On multivariate analysis, stage 3 PGD was significantly associated with donor blood transfusion (OR 2.69, IC (1.14-6.38), P = .024). Mortality at days 28 and 90 was not significantly different according to the pre-donation transfusion status of the donor. CONCLUSION: Pre-donation blood transfusion is associated with stage 3 PGD occurrence after LT. Transfusion data of the donor should be included in donor lung assessment.

Impact of rapid multiplex PCR on management of antibiotic therapy in COVID-19-positive patients hospitalized in intensive care unit.

Because the diagnosis of co/superinfection in COVID-19 patients is challenging, empirical antibiotic therapy is frequently initiated until microbiological analysis results. We evaluated the performance and the impact of the BioFire® FilmArray® Pneumonia plus Panel on 112 respiratory samples from 67 COVID-19 ICU patients suspected of co/superinfections. Globally, the sensitivity and specificity of the test were 89.3% and 99.1%, respectively. Positive tests led to antibiotic initiation or adaptation in 15% of episodes and de-escalation in 4%. When negative, 28% of episodes remained antibiotic-free (14% no initiation, 14% withdrawal). Rapid multiplex PCRs can help to improve antibiotic stewardship by administering appropriate antibiotics earlier and avoiding unnecessary prescriptions.

C4d detection and histological patterns in the diagnosis of antibody-mediated rejection after lung transplantation: a single-centre study.

AIMS: Antibody-mediated rejection (AMR) is an emerging and challenging issue in transplantation. Endothelial deposition of C4d and microvascular inflammation (MI) are reliable markers of AMR in renal and cardiac transplantation, but remain controversial in the lung. Our aim was to assess C4d immunohistochemistry and histological patterns for the diagnosis of lung AMR. METHODS AND RESULTS: We reviewed 158 transbronchial biopsies (TBBs) (n = 85 clinically indicated, and n = 73 surveillance TBBs) from 48 recipients, blinded to clinical and serological data. C4d was scored as 0, 1+ (<10%), 2+ (10-50%) or 3+ (>50%). TBBs were reassessed for MI and acute lung injury (ALI). Donor-specific antibodies (DSAs), acute clinical graft dysfunction and chronic lung allograft graft dysfunction (CLAD) were recorded. C4d3+, C4d2+, C4d1+ and C4d0 occurred respectively in four (2.5%), six (3.8%), 28 (17.7%) and 120 (75.9%) TBBs. MI and ALI were rare but more frequent in C4d1-3+ TBBs than in the absence of C4d. C4d2+ was frequently observed with concomitant infection. Among the surveillance TBBs, only two (2.7%) showed MI. Neither ALI nor C4d3+ was diagnosed on surveillance TBBs. No significant association was found between histopathological findings and DSAs. All four patients with C4d3+ could retrospectively be diagnosed with AMR and developed CLAD. CONCLUSION: Although rare, diffuse C4d deposition appears to be a strong indication of acute clinical AMR in lung transplant patients, whereas intermediate C4d2+ requires more investigations. In stable patients, histopathology and C4d may lack the sensitivity to diagnose subclinical AMR. This emphasises the need for a multidisciplinary evaluation of each suspected AMR case, and the need for complementary diagnostic tools.

A quantified description of the interactions between the native cardiovascular system and femoro-femoral versus femoro-axillary extracorporeal life support using descending thoracic aorta velocity time integral.

Extracorporeal life support (ECLS) is an important tool in managing severe cardio-circulatory and respiratory failures. The axillary and the femoral sites are the most frequently used for arterial cannulation. There is no current evidence favoring one site over the other. We tested the hypothesis that the axillary and femoral arterial cannulation site may have different effects on left ventricular (LV) outflow. Seven patients with femoro-axillary ECLS and 4 patients with femoro-femoral ECLS were prospectively studied using the Pulse-wave Doppler (PWD) velocity time integral (VTI) in the descending thoracic aorta (DTA VTI) at different short-time variations of ECLS flow rates during the ECLS weaning process. The measurements were safe and feasible in all patients. We found a directly proportional correlation between DTA VTI and ECLS flow rate for femoro-axillary cannulation (P < 0.05) and an inversely proportional correlation in the case of femoro-femoral cannulation (P < 0.05). This is the first reported utilization of DTA VTI during ECLS that could improve our understanding of the LV-aorta interactions in patients with ECLS. DTA VTI could be used as a tool, guiding weaning from ECLS.

Role of C1q-binding anti-HLA antibodies as a predictor of lung allograft outcome.

Presence of anti-human leukocyte antigen donor-specific antibodies (DSAs) is associated with poor outcome after lung transplantation. Currently, DSAs are detected using the Luminex technique, which may be overly sensitive. The new C1q assay allows for the exclusive detection of complement (C1q)-binding antibodies, involved in antibody-mediated rejection. We investigated whether early detection of complement-binding DSAs is associated with chronic lung allograft dysfunction (CLAD) and survival.From 2009 to 2012, lung transplant recipients from three transplantation centres were screened for the presence of DSA and their complement-binding capacity during the 6-12 months post-transplantation in a stable condition.The analysis included 168 patients. The 3-year rates of freedom from CLAD and graft survival were lower for patients with complement-binding DSAs (33.6% and 53.7%, respectively), as compared with patients with non-complement-binding DSAs (61.9% and 77.4%, respectively) and patients without DSA (70% and 84.9%, respectively) (p<0.001 and p=0.001, respectively). Detection of complement-binding DSA was associated with a risk of graft loss that was nearly tripled after adjustment for clinical, functional, histological and immunological factors (hazard ratio 2.98, 95% CI 1.33-6.66; p=0.008).Assessment of the C1q-binding capacity of DSA appears to be useful in identifying stable lung transplant recipients at high risk of lung allograft loss.

Thoracic Epidural Analgesia and Mortality in Acute Pancreatitis: A Multicenter Propensity Analysis.

OBJECTIVE: Recent preclinical and clinical data suggest that thoracic epidural analgesia, a technique primarily aimed at decreasing pain, might exert anti-inflammatory effects, enhance splanchnic and pancreatic blood flow during acute pancreatitis; however, the influence of epidural analgesia on mortality remains under investigated in this setting. This study was therefore designed to assess the impact of epidural analgesia on mortality in ICU patients with acute pancreatitis. DESIGN: Multicenter retrospective, observational, cohort study. SETTING: Seventeen French and Belgian ICUs. PATIENTS: All patients admitted to with acute pancreatitis between June 2009 and March 2014. INTERVENTIONS: The primary exposure was thoracic epidural analgesia versus standard care without epidural analgesia. The primary outcome was 30-day mortality. Propensity analyses were used to control for bias in treatment assignment and prognostic imbalances. MEASUREMENTS AND MAIN RESULTS: One thousand three ICU patients with acute pancreatitis were enrolled, of whom 212 died within 30 days. Epidural analgesia was used in 46 patients and was associated with reduced mortality in unadjusted analyses (4% vs. 22%; p = 0.003). After adjustment for baseline variables associated with mortality, epidural analgesia was still an independent predictor of 30-day mortality (adjusted odds ratio, 0.10; [95% CI, 0.02-0.49]; p = 0.004). Using propensity score analysis, the risk of all-cause 30-day mortality in patients with acute pancreatitis receiving epidural analgesia was significantly lower than that in matched patients who did not receive epidural analgesia (2% vs. 17%; p = 0.01). CONCLUSIONS: Among critically ill patients with acute pancreatitis, mortality at 30 days was lower in patients who received epidural analgesia than in comparable patients who did not. These findings support ongoing research on the use of epidural analgesia as a therapeutic intervention in acute pancreatitis.

Unbiased plasma proteomics for novel diagnostic biomarkers in cardiovascular disease: identification of quiescin Q6 as a candidate biomarker of acutely decompensated heart failure.

AIMS: Biochemical marker testing has improved the evaluation and management of patients with cardiovascular diseases over the past decade. Natriuretic peptides (NPs), used in clinical practice to assess cardiac dysfunction, exhibit many limitations, however. We used an unbiased proteomics approach for the discovery of novel diagnostic plasma biomarkers of heart failure (HF). METHODS AND RESULTS: A proteomics pipeline adapted for very low-abundant plasma proteins was applied to clinical samples from patients admitted with acute decompensated HF (ADHF). Quiescin Q6 (QSOX1), a protein involved in the formation of disulfide bridges, emerged as the best performing marker for ADHF (with an area under the receiver operator characteristic curve of 0.86, 95% confidence interval: 0.79-0.92), and novel isoforms of NPs were also identified. Diagnostic performance of QSOX1 for ADHF was confirmed in 267 prospectively collected subjects of whom 76 had ADHF. Combining QSOX1 to B-type NP (BNP) significantly improved diagnostic accuracy for ADHF by particularly improving specificity. Using thoracic aortic constriction in rats, QSOX1 was specifically induced within both left atria and ventricles at the time of HF onset. CONCLUSION: The novel biomarker QSOX1 accurately identifies ADHF, particularly when combined with BNP. Through both clinical and experimental studies we provide lines of evidence for a link between ADHF and cardiovascular production of QSOX1.

Donors brain-dead after successful resuscitation of cardiac arrest: Early outcome and postoperative complications of lung recipients.

BACKGROUND: The outcomes of lung transplantation (LT) recipients who received a graft from a brain-dead donor after successful resuscitation from cardiac arrest (CA donors) have been poorly described. This study compared the one-year survival of LT recipients depending on the CA status of the donor. METHODS: This prospective observational single-centre study analysed all consecutive patients who underwent LT at Bichat Claude Bernard Hospital, Paris, between January 2016 and December 2020. All donors who experienced CA prior to organ donation, regardless of rhythm or duration, were considered CA donors. The postoperative complications and outcomes of LT recipients were analysed. The one-year survival was compared using Kaplan-Meier curves and log-rank tests. Independent risk factors for one-year mortality were assessed using multivariate analysis (p < 0.05 was considered significant). The Paris North Hospitals Institutional Review Board approved the study. RESULTS: A total of 236 LT recipients were analysed and 66 (28%) received a graft from a CA donor. The median durations of no/low flow were 4 [0-10]/20 [15-30] minutes, respectively. Shockable and non-shockable rhythms were observed in 11 (17%) and 47 (72%) of the CA donors, respectively. The characteristics of the grafts and early postoperative complications were not different in the CA and non-CA groups. Receiving a graft from a CA donor was not an independent risk factor for recipient one-year mortality. CONCLUSION: Receiving a graft from a CA donor did not worsen the outcome of LT recipients. Acceptation of these grafts must be systematically considered to increase the pool of available grafts.

A 24-Year-Old Woman With Cough, Arthralgia, and Skin Ulcerations.

CASE PRESENTATION: A 24-year-old Senegalese woman without remarkable history except anemia and iron deficiency related to excessive menstrual bleeding and sickle cell trait was admitted to our internal medicine department with 4-month fever, weight loss (-13 kg), dyspnea for limited efforts, intermittent productive cough, and bilateral metacarpophalangeal (MCP) and interphalangeal arthralgia. She was born and lived in France. She traveled previously to Senegal in 2015. She had no history of tobacco, alcohol, or drug use nor proximity with animals. She was taking no medication.
