RESUMO

BACKGROUND: Detailed information about lung cancer patients requiring admission to intensive care units (ICUs) is mostly restricted to single-center studies. Our aim was to evaluate the clinical characteristics and outcomes of lung cancer patients admitted to ICUs. PATIENTS AND METHODS: Prospective multicenter study in 449 patients with lung cancer (small cell, n = 55; non-small cell, n = 394) admitted to 22 ICUs in six countries in Europe and South America during 2011. Multivariate Cox proportional hazards frailty models were built to identify characteristics associated with 30-day and 6-month mortality. RESULTS: Most of the patients (71%) had newly diagnosed cancer. Cancer-related complications occurred in 56% of patients; the most common was tumoral airway involvement (26%). Ventilatory support was required in 53% of patients. Overall hospital, 30-day, and 6-month mortality rates were 39%, 41%, and 55%, respectively. After adjustment for type of admission and early treatment-limitation decisions, determinants of mortality were organ dysfunction severity, poor performance status (PS), recurrent/progressive cancer, and cancer-related complications. Mortality rates were far lower in the patient subset with nonrecurrent/progressive cancer and a good PS, even those with sepsis, multiple organ dysfunctions, and need for ventilatory support. Mortality was also lower in high-volume centers. Poor PS predicted failure to receive the initially planned cancer treatment after hospital discharge. CONCLUSIONS: ICU admission was associated with meaningful survival in lung cancer patients with good PS and non-recurrent/progressive disease. Conversely, mortality rates were very high in patients not fit for anticancer treatment and poor PS. In this subgroup, palliative care may be the best option.

RESUMO

Pneumonia may be complicated by necrosis and destruction of lung tissue due to factors related to both pathogen and host as well as to their interactions. Lung necrosis may lead to two main entities sharing common features, but also several clinical and pathological differences: lung abscesses and necrotizing pneumonia. Necrotizing pneumonia is characterized by diffuse, possibly bilateral, lung parenchyma inflammation with multiple cavitations and necrosis. Necrotizing pneumonia is usually associated with severe sepsis and acute respiratory failure. Adequate antibiotics, mechanical ventilation, pleural drainage, and prolonged supportive care are mandatory. Adult patients with necrotizing pneumonia may require surgery. In our practice, indications for surgery are: (1) uncontrolled sepsis in spite of medical therapy and chest drainage; (2) major air leaks responsible for ventilation difficulties with serious hypoxemia/hypercapnia; and (3) hemodynamic disturbances by compression of vena cava and/or right heart cavities by tumor-like forms. Surgical treatment should be adapted to each case. Despite serious morbidity, massive parenchyma damage and prolonged hospitalization, long-term outcome following necrotizing pneumonia seems good when multidisciplinary care management is used in these patients with unusual but severe respiratory infectious disease.

RESUMO

Skin allografts survived longer on ALS-treated, complement-deficient (C5 negative) recipients than on ALS-treated, complement-competent (C5 positive) recipients. Administration of C5-positive serum to C5-negative, ALS-treated recipients resulted in reduced graft survival. A percentage of grafts from ALS-treated, C5-positive donors was rejected when transferred to untreated syngeneic recipients; this was not observed when C5-negative, syngeneic animals served as ALS-treated donors and untreated recipients. It was concluded that ALS has graft-rejecting properties which are promoted by late acting complement components. Unlike ALS-mediated graft rejection, ALS-mediated immunosuppression appeared to be independent of the late acting complement components. The effect of ALS on the humoral response to sheep erythrocytes was examined in complement-deficient and complement-competent mice. Immune-suppression was determined by ALS treatment of C5-competent and C5-deficient mice and also by transfer of in vitro ALS-treated spleen cells from C5-negative and C5-positive donors to cyclophosphamide-treated recipients. The ability of ALS to depress the humoral response to sheep cells and to decrease immunological competence of spleen cells was the same in the presence as in the absence of C5.

RESUMO

INTRODUCTION: The relations between chronic obstructive pulmonary disease (COPD) and respiratory diseases due to Aspergillus spp. are not well understood. METHODS: We analysed a retrospective series of patients hospitalized with a diagnosis of COPD and respiratory disease due to Aspergillus. Patients were identified between 2010 and 2015 from the medico-administrative database of Cochin hospital, Paris. Historical, clinical, biological, microbiological and imaging data were collected and described. Diagnoses were reclassified based on reference definitions and classifications from the literature. Patients were classified according to the type of Aspergillus-related diseases and risk factors were described. RESULTS: Forty patients were identified. Classifiable Aspergillus-related respiratory conditions were confirmed in 26 of them including 12 allergic bronchopulmonary aspergillosis (ABPA), 8 chronic pulmonary aspergillosis (CPA), 1 invasive pulmonary aspergillosis (IPA) and 3 diagnostic associations ABPA/CPA. Other respiratory comorbidities were present in all cases of CPA and immunodepression was recorded for semi-invasive and invasive forms. Finally, 16 patients could not be classified, among whom Aspergillus related lung disease was considered as likely in one-half. CONCLUSION: The complexity of the diagnosis of pulmonary aspergillosis is related to its multiple types with sometimes unclear distinctions. Any type of pulmonary aspergillosis can be observed in patients with COPD, depending on associated risks factors. It would be helpful to establish specific classifications adapted to patients with COPD. This will require larger, prospective, multicentre studies.

RESUMO

Mucosa-associated lymphoid tissue-derived (MALT) lymphoma, a low grade B-cell extranodal lymphoma, is the most frequent subset of primary pulmonary lymphoma. Our objective was to evaluate the initial extent of disease and to analyse the characteristics and long-term outcome of these patients. All chest and pathological departments of teaching hospitals in Paris were contacted in order to identify patients with a histological diagnosis of primary pulmonary lymphoma of the MALT subtype. 63 cases were identified. The median age was 60 yrs. 36% of cases had no symptoms at diagnosis. 46% of patients had at least one extrapulmonary location of lymphoma. The estimated 5- and 10-yr overall survival rates were 90% and 72%, respectively. Only two of the nine observed deaths were related to lymphoma. Age and performance status were the only two adverse prognostic factors for survival. Extrapulmonary location of lymphoma was not a prognostic factor for overall survival or for progression-free survival. Treatment with cyclophosphamide or anthracycline was associated with shorter progression-free survival, when compared with chlorambucil. The survival data confirm the indolent nature of pulmonary MALT lymphoma. Better progression-free survival was observed with chlorambucil when compared with cyclophosphamide or anthracycline.

RESUMO

AIM: A multicentre retrospective study was undertaken to examine patients with interstitial lung disease (ILD) with the initial clinical manifestation of an anti-synthetase syndrome (anti-Jo-1 antibodies), and to analyse the characteristics and long-term outcome of these patients according to their clinical presentation (acute or gradual onset), treatment and adverse events related to treatment. METHODS: 32 patients, 15 (47%) presenting with acute onset and associated respiratory insufficiency (group A) and 17 (53%) with gradual onset (group G) were examined. Myositis was diagnosed at admission in only 31% of cases and was observed during follow-up in 56% of cases, but the prevalence did not differ between the two groups. RESULTS: Fever and radiological patterns including diffuse patchy ground-glass opacities, basal irregular lines and consolidation on high-resolution CT scan were more frequent in group A than in group G. More patients in group G had neutrophils in the bronchoalveolar lavage fluid and autoantibodies other than anti-Jo-1 (rheumatoid factor, anti SSa/SSb) than in group A. The percentage of patients in whom the ILD improved at 3 months was significantly higher in group A than in group G (13/15 vs 9/17; p = 0.006). In contrast, after 12 months, most patients with ILD progression were in group A and were treated with corticosteroids alone. A combination of corticosteroids and an immunosuppressive drug was required in most cases (84%) at the end of the follow-up period. Severe adverse effects of treatment were observed and varicella zoster virus infection was frequent. CONCLUSIONS: Early testing for anti-synthetase antibodies, particularly anti-Jo-1, and creatine kinase determination are useful procedures in patients presenting with ILD. Treatment with corticosteroids and immunosuppressive drugs is required in most patients. At the end of the study, around two-thirds of patients had stable ILD while the other third had disease progression with respiratory insufficiency.

RESUMO

Community-acquired pneumonia (CAP) is a common infectious disease and one of the main causes of mortality worldwide. Despite an improvement in management globally, mortality remains high especially in severe forms of CAP. Adequate early antibiotics remain the cornerstone of the treatment but adjuvant corticosteroid administration is being considered to counterbalance the systemic inflammatory reaction and modulate the immune response. In the last ten years, several clinical trials and meta-analyses have been conducted in severe and non-severe CAP to assess the efficacy of corticosteroids. The benefits on the duration of hospitalization and the time to clinical stability are quite small and early mortality does not seem to be improved. Corticosteroids should not, therefore, be used routinely in patients with CAP, even in severe cases. However, new therapeutic trials are currently underway.

RESUMO

BACKGROUND: Although patients with advanced or metastatic lung cancer have poor prognosis, admission to the ICU for management of life-threatening complications has increased over the years. Patients with newly diagnosed lung cancer appear as good candidates for ICU admission, but more robust information to assist decisions is lacking. The aim of our study was to evaluate the prognosis of newly diagnosed unresectable lung cancer patients. METHODS: A retrospective multicentric study analyzed the outcome of patients admitted to the ICU with a newly diagnosed lung cancer (diagnosis within the month) between 2010 and 2013. RESULTS: Out of the 100 patients, 30 had small cell lung cancer (SCLC) and 70 had non-small cell lung cancer. (Thirty patients had already been treated with oncologic treatments.) Mechanical ventilation (MV) was performed for 81 patients. Seventeen patients received emergency chemotherapy during their ICU stay. ICU, hospital, 3- and 6-month mortality were, respectively, 47, 60, 67 and 71%. Hospital mortality was 60% when invasive MV was used alone, 71% when MV and vasopressors were needed and 83% when MV, vasopressors and hemodialysis were required. In multivariate analysis, hospital mortality was associated with metastatic disease (OR 4.22 [1.4-12.4]; p = 0.008), need for invasive MV (OR 4.20 [1.11-16.2]; p = 0.030), while chemotherapy in ICU was associated with survival (OR 0.23, [0.07-0.81]; p = 0.020). CONCLUSION: This study shows that ICU management can be appropriate for selected newly diagnosed patients with advanced lung cancer, and chemotherapy might improve outcome for patients with SCLC admitted for cancer-related complications. Nevertheless, tumors' characteristics, numbers and types of organ dysfunction should be taken into account in the decisional process before admitting these patients in ICU.

RESUMO

PURPOSE: The objectives of our study were to describe the outcome of patients with malignancies treated for acute respiratory distress syndrome (ARDS) with noninvasive ventilation (NIV) and to evaluate factors associated with NIV failure. METHODS: Post hoc analysis of a multicenter database within 20 years was performed. All patients with malignancies and Berlin ARDS definition were included. Noninvasive ventilation use was defined as NIV lasting more than 1 hour, whereas failure was defined as a subsequent requirement of invasive ventilation. Conditional backward logistic regression analyses were conducted. RESULTS: A total of 1004 met the Berlin definition of ARDS. Noninvasive ventilation was used in 387 patients (38.6%) and NIV failure occurred in 71%, with an in-hospital mortality of 62.7%. Severity of ARDS defined by the partial pressure arterial oxygen and fraction of inspired oxygen ratio (odds ratio [OR], 2.20; 95% confidence interval [CI], 1.15-4.19), pulmonary infection (OR, 1.81; 95% CI, 1.08-3.03), and modified Sequential Organ Failure Assessment (SOFA) score (OR, 1.13; 95% CI, 1.06-1.21) were associated with NIV failure. Factors associated with hospital mortality were NIV failure (OR, 2.52; 95% CI, 1.56-4.07), severe ARDS as compared with mild ARDS (OR, 1.89; 95% CI, 1.05-1.19), and modified SOFA score (OR, 1.12; 95% CI, 1.05-1.19). CONCLUSION: Noninvasive ventilation failure in ARDS patients with malignancies is frequent and related to ARDS severity, SOFA score, and pulmonary infection-related ARDS. Noninvasive ventilation failure is associated with in-hospital mortality.

RESUMO

Chronic obstructive pulmonary disease (COPD) is the chronic respiratory disease with the most important burden on public health in terms of morbidity, mortality and health costs. For patients, COPD is a major source of disability because of dyspnea, restriction in daily activities, exacerbation, risk of chronic respiratory failure and extra-respiratory systemic organ disorders. The previous French Language Respiratory Society (SPLF) guidelines on COPD exacerbations were published in 2003. Using the GRADE methodology, the present document reviews the current knowledge on COPD exacerbation through 4 specific outlines: (1) epidemiology, (2) clinical evaluation, (3) therapeutic management and (4) prevention. Specific aspects of outpatients and inpatients care are discussed, especially regarding assessment of exacerbation severity and pharmacological approach.
