Tients admitted in the ICU for ARDS according to the Berlin definition criteria (inside 48 h of admission) and receiving invasive mechanical ventilation over a 10-year period (January 2006 to December 2015) had been integrated [12]. Exclusion criteria were as follows: previously known lung interstitial disease or tumoral infiltration, chronic respiratory failure requiring long-term oxygen therapy, pure cardiogenic pulmonary edema, mild ARDS treated with noninvasive ventilation only, established or suspected invasive pulmonary aspergillosis under antifungal therapy upon ARDS diagnosis and sufferers for whom no endobronchial sampling had been obtained. All respiratory tract samples (plugged telescoping catheter, tracheal aspirate or bronchoalveolar fluid) performed for microbiological examination have been analyzed. Galactomannan antigen (GM) detection in plasma and in bronchoalveolar lavage (BAL) fluid was performed at the discretion of your managing physician. An opticalPatients have been categorized into two groups: those with a single or much more respiratory tract sample positive in culture for Aspergillus spp. (Aspergillus+ patients) throughout the ICU remain and these with out such optimistic sample (Aspergillus- sufferers). The former group was additional split into three categories depending on the probability of IPA based on the clinical algorithm proposed by Blot et al. [16]: (A) established IPA (microscopic evaluation on sterile material: histopathologic, cytopathologic or PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21301260 direct microscopic examination of a specimen obtained by needle aspiration or sterile biopsy in which hyphae are observed accompanied by evidence of associated tissue harm; isolation of Aspergillus from culture of a specimen obtained by lung biopsy); (B) putative IPA in case of (1) Aspergillus-positive decrease respiratory tract specimen culture (entry criterion) with (2) compatible indicators and symptoms (one of the following: fever refractory to no less than three days of suitable antibiotic therapy, recrudescent fever soon after a period of defervescence of at the very least 48 h even though nonetheless on antibiotics and with out other apparent cause, pleuritic chest pain, pleuritic rub, dyspnea, hemoptysis, worsening respiratory insufficiency in spite of acceptable antibiotic therapy and ventilatory support) and (3) abnormal healthcare imaging by transportable chest X-ray or CT scan on the lungs, and either (4a) a host danger issue (one of the following conditions: neutropenia (absolute neutrophil count 500 GL) preceding or in the time of ICU admission, underlying hematological or oncological malignancy treated with cytotoxic agents, glucocorticoid therapy (prednisone equivalent 20 mgday), congenital or acquired immunodeficiency) or (4b) a semiquantitative Aspergillus-positive culture of BAL fluid (+ or +++), without having bacterial development with each other having a optimistic cytological smear displaying branching hyphae or (C) Aspergillus respiratory tract colonization when 1 criterion essential to get a diagnosis of putative IPA was not met (Tables 1, 2).Collection of data and definitionsDemographics and clinical traits upon ICU admission and during ICU stay had been abstracted from the healthcare charts of all patients. Immunosuppression was defined by certainly one of the following situations: neutropenia (absolute neutrophil count 500 GL) preceding or at the time of ICU admission, underlying hematological or oncological malignancy treated with cytotoxic agents, glucocorticoid therapy (prednisone equivalent 20 mgContou et al.
