RESUMO

Lung transplantation is limited by the shortage of suitable donors. Many programs have begun to use extended criteria donors. Donors over 65 years old are rarely reported, especially for young cystic fibrosis recipients. This monocentric study was conducted for cystic fibrosis recipients from January 2005 to December 2019, comparing two cohorts according to lung donor age (<65 years or ≥65 years). The primary objective was to assess the survival rate at 3 years using a Cox multivariable model. Of the 356 lung recipients, 326 had donors under 65 years, and 30 had donors over 65 years. Donors' characteristics did not differ significantly in terms of sex, time on mechanical ventilation before retrieval, and partial pressure of arterial oxygen/fraction of inspired oxygen ratio. There were no significant differences in post-operative mechanical ventilation duration and incidence of grade 3 primary graft dysfunction between the two groups. At 1, 3, and 5 years, the percentage of predicted forced expiratory volume in 1 s (p = 0.767) and survival rate did not differ between groups (p = 0.924). The use of lungs from donors over 65 years for cystic fibrosis recipients allows extension of the donor pool without compromising results. Longer follow-up is needed to assess the long-term effects of this practice.

RESUMO

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections are closely monitored in people with cystic fibrosis (pwCF), especially severe cases. Previous studies used hospitalization rates as proxy for severity. METHODS: We evaluated data from coronavirus disease 2019 (COVID-19) cases diagnosed in French pwCF over the first pandemic year. Objective criteria were applied for defining severity (eg, respiratory failure and/or death). Data were compared to all French pwCF using the National Registry. RESULTS: As of 30 April 2021, 223 pwCF were diagnosed with COVID-19, with higher risks in adults (odds ratio [OR], 2.52 [95% confidence interval {CI}, 1.82-3.48]) and transplant recipients (OR, 2.68 [95% CI, 1.98-3.63]). Sixty (26.9%) patients were hospitalized, with increased risk in transplant recipients (OR, 4.74 [95% CI, 2.49-9.02]). In 34 (15%) cases, COVID-19 was considered severe; 28 (46.7%) hospitalizations occurred without objective criteria of severity. Severe cases occurred mostly in adult (85.3%) and posttransplant pwCF (61.8%; OR, 6.02 [95% CI, 2.77-13.06]). In nontransplanted pwCF, risk factors for severity included low lung function (median percentage of predicted forced expiratory volume in 1 second, 54.6% vs 75.1%; OR, 1.04 [95% CI, 1.01-1.08]) and CF-related diabetes (OR, 3.26 [95% CI, 1.02-10.4]). While 204 cases fully recovered, 16 were followed for possible sequelae, and 3 posttransplant females died. CONCLUSIONS: Severe COVID-19 occurred infrequently during the first pandemic year in French pwCF. Nontransplanted adults with severe respiratory disease or diabetes and posttransplant individuals were at risk for severe COVID-19. Thus, specific preventive measures should be proposed.

RESUMO

BACKGROUND: Pre-formed donor-specific antibodies (DSAs) are associated with worse outcome after lung transplantation (LTx) and might limit access to LTx. A virtual crossmatch-based strategy for perioperative desensitisation protocol has been used for immunised LTx candidates since 2012 at Foch Hospital (Suresnes, France). We compared the outcome of desensitised LTx candidates with high DSA mean fluorescence intensity and those with low or no pre-formed DSAs, not desensitised. METHODS: For all consecutive LTx recipients (January 2012 to March 2018), freedom from chronic lung allograft dysfunction (CLAD) and graft survival were assessed using Kaplan-Meier analysis and Cox multivariate analysis. RESULTS: We compared outcomes for desensitised patients with high pre-formed DSAs (n=39) and those with no (n=216) or low pre-formed DSAs (n=66). The desensitisation protocol decreased the level of immunodominant DSA (class I/II) at 1, 3 and 6 months post-LTx (p<0.001, p<0.01 and p<0.001, respectively). Freedom from CLAD and graft survival at 3 years was similar in the desensitised group as a whole and other groups. Nevertheless, incidence of CLAD was higher with persistent high-level DSAs than cleared high-level (p=0.044) or no DSAs (p=0.014). Conversely, graft survival was better with cleared high DSAs than persistent high-level, low-level and no pre-formed DSAs (p=0.019, p=0.025 and p=0.044, respectively). On multivariate analysis, graft survival was associated with cleared high DSAs (hazard ratio 0.12, 95% CI 0.02-0.85 versus no DSAs; p=0.035) and CLAD with persistent DSAs (3.04, 1.02-9.17 versus no pre-formed DSAs; p=0.048). CONCLUSION: The desensitisation protocol in LTx recipients with high pre-formed DSAs was associated with satisfactory outcome, with cleared high pre-formed DSAs after desensitisation identified as an independent predictor of graft survival.

RESUMO

Many candidates for lung transplantation (LT) die on the waiting list, raising the question of graft availability and strategy for organ allocation. We report the experience of the new organ allocation program, "High Emergency Lung Transplantation" (HELT), since its implementation in our center in 2007. Retrospective analysis of 201 lung transplant patients, of whom 37 received HELT from 1st July 2007 to 31th May 2012. HELT candidates had a higher impairment grade on respiratory status and higher Lung Allocation Score (LAS). HELT patients had increased incidence of perioperative complications (e.g., perioperative bleeding) and extracorporeal circulatory assistance (75% vs. 36.6%, P = 0.0005). No significant difference was observed between HELT and non-HELT patients in mechanical ventilation duration (15.5 days vs. 11 days, P = 0.27), intensive care unit length of stay (15 days vs. 10 days, P = 0.22) or survival rate at 12 (81% vs. 80%), and 24 months post-LT (72.9% vs. 75.0%). Lastly, mortality on the waiting list was spectacularly reduced from 19% to 2% when compared to the non-HELT 2004-2007 group. Despite a more severe clinical status of patients on the waiting list, HELT provided similar results to conventional LT. These results were associated with a dramatic reduction in the mortality rate of patients on the waiting list.

RESUMO

INTRODUCTION: ICU admission is required in more than 25% of patients with chronic obstructive pulmonary disease (COPD) at some time during the course of the disease. However, only limited information is available on how physicians communicate with COPD patients about ICU admission. METHODS: COPD patients and relatives from 19 French ICUs were interviewed at ICU discharge about their knowledge of COPD. French pulmonologists self-reported their practices for informing and discussing intensive care treatment preferences with COPD patients. Finally, pulmonologists and ICU physicians reported barriers and facilitators for transfer of COPD patients to the ICU and to propose invasive mechanical ventilation. RESULTS: Self-report questionnaires were filled in by 126 COPD patients and 102 relatives, and 173 pulmonologists and 135 ICU physicians were interviewed. For 41% (n = 39) of patients and 54% (n = 51) of relatives, ICU admission had never been expected prior to admission. One half of patients were not routinely informed by their pulmonologist about possible ICU admission at some time during the course of COPD. Moreover, treatment options (that is, non-invasive ventilation, intubation and mechanical ventilation or tracheotomy) were not explained to COPD patients during regular pulmonologist visits. Pulmonologists and ICU physician have different perceptions of the decision-making process pertaining to ICU admission and intubation. CONCLUSIONS: The information provided by pulmonologists to patients and families concerning the prognosis of COPD, the risks of ICU admission and specific care could be improved in order to deliver ICU care in accordance with the patient's personal values and preferences. Given the discrepancies in the decision-making process between pulmonologists and intensivists, a more collaborative approach should probably be discussed.

RESUMO

Lung transplantation (LTx) is a steadily expanding field. The considerable developments have been driven over the years by indefatigable work conducted at LTx centers to improve donor and recipient selection, combined with multifaceted efforts to overcome challenges raised by the surgical procedure, perioperative care, and long-term medical complications. One consequence has been a pruning away of contraindications over time, which has, in some ways, complicated the patient selection process. The Francophone Pulmonology Society (Société de Pneumology de Langue Française, SPLF) set up a task force to produce up-to-date working guidelines designed to assist pulmonologists in managing end-stage respiratory insufficiency, determining which patients may be eligible for LTx, and appropriately timing LTx-center referral. The task force examined the most recent literature and evaluated the risk factors that limit patient survival after LTx. Ideally, the objectives of LTx are to prolong life while also improving quality of life. The guidelines developed by the task force apply to a limited resource and are consistent with the ethical principles described below.

RESUMO

OBJECTIVE: To determine the prevalence and risk factors of symptoms of anxiety, depression, and posttraumatic stress disorder-related symptoms in patients with chronic obstructive pulmonary disease and their relatives after an intensive care unit stay. DESIGN: Prospective multicenter study. SETTING: Nineteen French intensive care units. SUBJECTS: One hundred twenty-six patients with chronic obstructive pulmonary disease who survived an intensive care unit stay and 102 relatives. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Patients and relatives were interviewed at intensive care unit discharge and 90 days later to assess symptoms of anxiety and depression using Hospital Anxiety and Depression Scale (HADS) and posttraumatic stress disorder-related symptoms using the Impact of Event Scale (IES). At intensive care unit discharge, 90% of patients recollected traumatic psychological events in the intensive care unit. At day 90, we were able to conduct telephone interviews with 53 patients and 47 relatives. Hospital Anxiety and Depression Scale scores indicated symptoms of anxiety and depression in 52% and 45.5% of patients at intensive care unit discharge and in 28.3% and 18.9% on day 90, respectively. Corresponding prevalence in relatives were 72.2% and 25.7% at intensive care unit discharge and 40.4% and 14.9% on day 90, respectively. The Impact of Event Scale indicated posttraumatic stress disorder-related symptoms in 20.7% of patients and 29.8% of relatives on day 90. Peritraumatic dissociation assessed using the Peritraumatic Dissociative Experiences Questionnaire was independently associated with posttraumatic stress disorder-related symptoms in the patients and relatives. Previous intensive care unit experience and recollection of bothersome noise in the intensive care unit predicted posttraumatic stress disorder-related symptoms in the patients. CONCLUSIONS: Psychiatric symptoms were found to be common in a group of 126 patients with chronic obstructive pulmonary disease who survived an intensive care unit stay and their relatives at intensive care unit discharge and 90 days later. Peritraumatic dissociation at intensive care unit discharge was found to independently predict posttraumatic stress disorder-related symptoms in this sample of patients and relatives.

RESUMO

Viral infections are known to lead to serious respiratory complications in cystic fibrosis (CF) patients. Hypothesizing that CF patients were a population at high risk for severe respiratory complications from SARS-CoV-2 infection, we conducted a national study to describe the clinical expression of COVID-19 in French CF patients. This prospective observational study involves all 47 French CF centers caring for approximately 7500 CF patients. Between March 1st and June 30th 2020, 31 patients were diagnosed with COVID-19: 19 had positive SARS-CoV-2 RT-PCR in nasopharyngeal swabs; 1 had negative RT-PCR but typical COVID-19 signs on a CT scan; and 11 had positive SARS-CoV-2 serology. Fifteen were males, median (range) age was 31 (9-60) years, and 12 patients were living with a lung transplant. The majority of the patients had CF-related diabetes (n = 19, 61.3%), and a mild lung disease (n = 19, 65%, with percent-predicted forced expiratory volume in 1 s (ppFEV1) > 70). Three (10%) patients remained asymptomatic. For the 28 (90%) patients who displayed symptoms, most common symptoms at admission were fever (n = 22, 78.6%), fatigue (n = 14, 50%), and increased cough (n = 14, 50%). Nineteen were hospitalized (including 11 out of the 12 post-lung transplant patients), seven required oxygen therapy, and four (3 post-lung transplant patients) were admitted to an Intensive Care Unit (ICU). Ten developed complications (including acute respiratory distress syndrome in two post-lung transplant patients), but all recovered and were discharged home without noticeable short-term sequelae. Overall, French CF patients were rarely diagnosed with COVID-19. Further research should establish whether they were not infected or remained asymptomatic upon infection. In diagnosed cases, the short-term evolution was favorable with rare acute respiratory distress syndrome and no death. Post-lung transplant patients had more severe outcomes and should be monitored more closely.

RESUMO

BACKGROUND: Pneumocystis pneumonia (PCP) is common in patients with HIV infection but may also occur in patients with other causes of immunodeficiency, including hematologic and solid malignancies. METHODS: To better describe the clinical picture of PCP as to maintain a high level of suspicion in adequate cases, we studied 56 cancer patients with PCP and compared them to 56 cancer patients with bacterial pneumonia. RESULTS: Among 56 PCP patients, 44 patients (78.6%) had hematologic malignancies (18 recipients of bone marrow transplantation) and 12 patients had solid tumors. The time since diagnosis was 24 months (range, 4 to 49 months). All patients with solid tumors and 20 patients (45.4%) with hematologic malignancies were receiving steroids. Only six patients were receiving PCP prophylaxis. The main symptoms were fever (85.7%), dyspnea (78.6%), and cough (57.1%). Time from symptom onset was 7 days (range, 3 to 14 days). PCP presented as severe pneumonia (Pao(2), 58 mm Hg [range, 50 to 70 mm Hg]) with bilateral interstitial infiltrates (80.4%) and bilateral ground-glass attenuation (89.3%) by CT. Of the 24 ICU patients (42.9%), 16 patients (19.6%) required mechanical ventilation. Eleven patients (19.6%) died. Compared to 56 patients with bacterial pneumonia, PCP patients were more likely to have non-Hodgkin lymphoma and be receiving long-term steroids; they had longer times since diagnosis, longer symptom duration, higher frequencies of fever and of diffuse lung disease (diffuse crackles, bilateral infiltrates, and hypoxemia), higher frequency of ground-glass opacities, and lower frequency of pleural involvement. CONCLUSIONS: PCP presents as subacute, febrile, hypoxemic, and diffuse pulmonary involvement in patients with solid tumors or hematologic malignancies receiving long-term steroids.

RESUMO

Although donor-specific anti-human leukocyte antigen (HLA) antibodies (DSAs) are frequently found in recipients after lung transplantation (LT), the characteristics of DSA which influence antibody-mediated rejection (AMR) in LT are not fully defined. We retrospectively analyzed 206 consecutive LT patients of our center (2010-2013). DSAs were detected by using luminex single antigen beads assay and mean fluorescence intensity was assessed. Within the study population, 105 patients had positive DSA. Patients with and without AMR (AMRPos, n = 22, and AMRNeg, n = 83, respectively) were compared. AMRPos patients had significantly greater frequencies of anti-HLA DQ DSA (DQ DSA) than AMRNeg patients (95 vs 58%, respectively, p < 0.0001). Compared to AMRNeg patients, AMRPos patients had higher DQ DSA sum MFI [7,332 (2,067-10,213) vs 681 (0-1,887), p < 0.0001]. DQ DSA when associated with AMR, had more frequent graft loss and chronic lung allograft dysfunction (CLAD). These data suggest (i) that DSA characteristics clearly differ between AMRPos and AMRNeg patients and (ii) the deleterious impact of DQ DSA on clinical outcome.

RESUMO

PURPOSE: To evaluate the outcome of cancer patients considered for admission to the intensive care unit (ICU). PATIENTS AND METHODS: Prospective, one-year hospital-wide study of all cancer and hematology patients, including bone marrow transplantation patients, for whom admission to the ICU was requested. RESULTS: Of the 206 patients considered for ICU admission, 105 patients (51%) were admitted. Of the 101 patients who were not admitted, 54 patients (26.2%) were considered too sick to benefit, and 47 patients (22.8%) were considered to be too well to benefit from the ICU. Of these 47 patients, 13 patients were admitted later. Survival rates after 30 and 180 days were significantly associated with admission status (P < .0001). Remission of the malignancy (odds ratio [OR], 3.37; 95% CI, 1.25 to 9.07) was independently associated with ICU admission, whereas poor chronic health status (OR, 0.38; 95% CI, 0.16 to 0.74) and solid tumor (OR, 0.43; 95% CI, 0.24 to 0.78) were associated with ICU refusal. In admitted patients, 30-day and 6-month survival rates were 54.3% and 32.4%, respectively. Of the patients considered too sick to benefit from ICU admission, 26% were alive on day 30 and 16.7% on day 180. Among patients considered too well to benefit, the 30-day survival rate was a worrisome 78.7%. Calibration of the Mortality Probability Model (the only score available at triage) was of limited value for predicting 30-day survival (area under the curve, 0.62). CONCLUSION: Both the excess mortality in too-well patients later admitted to the ICU and the relatively good survival in too-sick patients suggest the need for a broader admission policy.

RESUMO

Acute acalculous cholecystitis is a very rare gastrointestinal manifestation in systemic lupus erythematosus and becomes rarer as an initial manifestation. There are only two cases reported. The authors report a 20-year-old black woman that presented acute acalculous cholecystitis revealed by abdominal computed tomography. During hospitalization, she was diagnosed systemic lupus erythematosus. Conservative treatment with antibiotics was performed with complete remission of the symptoms. Corticosteroid was started in ambulatory. Cholecystectomy has been the treatment of choice in acute acalculous cholecystitis as a complication of systemic lupus erythematosus. The patient responded well to conservative treatment, and surgery was not required. This case is unique in the way that corticosteroid was started in ambulatory care. We should not forget that the acute acalculous cholecystitis can be the initial presentation of systemic lupus erythematosus although its occurrence is very rare. Conservative treatment should be considered. Abdominal computed tomography was a determinant exam for better assessment of acute acalculous cholecystitis.

RESUMO

The authors present a case of a hemorrhagic adrenal cyst, one of the tumors known in literature as incidentalomas, emphasizing the clinical characteristics, since adrenal cysts or pseudocysts are generally rare and observed by chance during imaging procedures. Traditionally they are classified as pseudocysts, endothelial, epithelial or parasitic cysts. Laparoscopic adrenalectomy has been considered the treatment of choice for benign, functioning or non-functioning adrenal lesions. Small cystic adrenal tumors can be managed conservatively by laparoscopic decortication or marsupialization, but larger cysts should be treated by total or partial adrenalectomy.

RESUMO

BACKGROUND: The exercise treadmill test can be used in ventricular dysfunction patients for functional capacity or predicting prognosis. The cardiac image with 123I MIBG shows cardiac sympathetic activation. OBJECTIVE: To evaluate the relationship between exercise treadmill test variables and cardiac image changes in 123I MIBG. METHODS: 23 patients with LVEF ≤ 45% performed scintigraphy cardiac with 123I MIBG and divided into two groups. G1: Washout rate < 27%; G2: ≥ 27%. Systolic blood pressure (SBP), heart rate (HR) and functional capacity were evaluated. It was performed Student t test or Mann-Whitney U test, Spearman coefficient and linear regression. RESULTS: SBP at exercise peak (G1: 181.00 ± 28.01; G2: 153.27 ± 27.71 mmHg, p = 0.027), SBP variation [G1: 64(47.5-80.5); G2: 36(25-47) mmHg, p = 0.015], the HR at exercise peak (G1: 136.91 ± 19.66; G2: 118.45 ± 13.98 bpm, p = 0.018) and chronotropic response (G1: 70.42 ± 17.94; G2: 49.47 ± 14.89%, p = 0.006), and functional capacity [G1: 8.37(6.47-10.27); G2: 4.42(2.46-6.38) METs, p = 0.003] were smaller in G2 group. There was negative correlation between Washout rate and SBP at exercise peak (r = -0.505, p = 0.014), variation in SBP (r = -0.493, p = 0.017) and functional capacity (r = -0.646, p = 0.001). Nevertheless, SBP at exercise peak (r = -0.422, p = 0.016) and functional capacity (r = -0.804, p = 0.004) were the only variables associated with Washout rate, after linear regression. CONCLUSION: In heart failure patients, the SBP at exercise peak and functional capacity were the variables associated with Washout rate.

RESUMO

OBJECTIVE: Patients with newly diagnosed cancer responsible for organ failures may require intensive care unit (ICU) admission and immediate chemotherapy. Outcomes in this population have not been studied. DESIGN: Prospective observational cohort study. SETTING: Teaching hospital. SUBJECTS: All patients admitted to the ICU, from January 1997 to June 2003, for organ failures due to newly diagnosed, untreated cancer and deemed necessary to receive immediate cancer chemotherapy. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: For the period of 6.5 yrs, 100 patients met the study criteria: 43 had acute leukemia, 37 lymphoma, and 12 solid tumors. Median Simplified Acute Physiology Score II was 39 (30-48) points, and median Logistic Organ Dysfunction score was 5 (3-7) points. Three variables were independently associated with 30-day mortality: need for vasopressor therapy (odds ratio, 6.01; 95% confidence interval, 1.86-19.4), mechanical ventilation (odds ratio, 6.36; 95% confidence interval, 1.76-22.94); and hepatic failure (odds ratio, 7.76; 95% confidence interval, 1.25-48.27). Overall survival was 60% after 30 days and 49% after 180 days. CONCLUSIONS: Mortality was chiefly dependent on the nature and number of organ failures, not on the nature or stage of the malignancy. The 30-day and 180-day survival rates indicate that, in this selected group of patients, advanced disease at cancer diagnosis should not lead to refusal of ICU admission.
