Active clinical trials for "Pneumonia"

Currently there is a great need for an accurately and rapid assessment of patients suspected for Covid-19. Like CT, Lung Ultrasound (LUS) examination can potentially help with the initial triage of patients but also help track the evolution of the disease. LUS can be used in every setting, including settings with limited infrastructure, allowing the reduction of disparities in trials participation. LUS is also a practical approach that can be used by obstetricians/gynecologists, who are the primary care givers in the labour and delivery room. The International Lung UltraSound Analysis (ILUSA) Study is an international multicenter prospective explorative observational study to assess the predictive value of LUS in Covid-19 suspected and diagnosed pregnant patients.

Background: Invasive mechanical ventilation (IMV) in COVID-19 patients has been associated with a high mortality rate. In this context, the utility of tracheostomy has been questioned in this group of ill patients. This study aims to compare in-hospital mortality in COVID-19 patients with and without tracheostomy due to prolonged IMV Methods: Cohort study of adult COVID-19 patients subjected to prolonged IMV. Since the first COVID-19 case (March 3, 2020) up to November 30, 2020, all adult critical patients supported with IMV by 10 days or more at the Hospital Clínico Universidad de Chile will be included in the cohort. Pregnant women and non-adult patients will be excluded. Baseline characteristics, comorbidities, laboratory data, disease severity, and ventilatory support will be retrospectively collected from clinical records. The indication of tracheostomy, as part of our standard of care, will be indicated by a team of specialists in intensive care medicine, following national guidelines, and consented to by the patient's family. The 90-days mortality rate will be the primary outcome, whereas IMV days, hospital/CU length of stay, and the frequency of healthcare-associated infections will be the secondary outcomes. Also, a follow-up interview will be performed one year after a hospital discharged in order to assess the vital status and quality of life. The mortality of patients subjected to tracheostomy will be compared with the group of patients without tracheostomy by logistic regression models. Furthermore, propensity-score methods will be performed as a complementary analysis.

In this retrospective study, we aim to investigate the demographic and clinical features of patients with nontuberculous mycobacteria (NTM) lung disease in our hospital and the trends and diversity of NTM species isolated in the period of 2009-2018.

The incidence rate and mortality of lung infection are high worldwide. It is a common and frequently occurring disease which seriously threatens human health. Severe pneumonia accounts for 18-36% of all pneumonia. Severe pneumonia has caused serious economic and medical burden. Therefore, it is urgent to carry out the real-world cohort study of severe pneumonia. Big data and sample library will provide useful clinical guidance and scientific research reserves for clinicians. Through further research, we can improve the treatment success rate and reduce the mortality. The purpose of this study is to provide reliable biological samples and related data information for the relevant basic and clinical trials in the field of severe pneumonia by carrying out the construction of special disease cohort database and biological sample holographic database, and to establish a long-term sharing platform for the transformation of research results into clinical practice, improve the prognosis of severe pneumonia,and provide the evidence for improving the diagnosis and treatment of severe pneumonia suitable for China's national conditions.

Pneumonia is a major cause of ICU admission, or may complicate ICU course. Among the causative pathogens, Stenotrophomonas Maltophilia is a rare pathogen, but affects usually patients with chronic pulmonary co-morbidities, or with long duration of mechanical ventilation and multiples treatment with broad spectrum antimicrobial therapy. However, there are only a paucity of data regarding epidemiology, impact and outcome of Pneumonia due to Stenotrophomonas Maltophilia in critically ill patients. Primary objective was to study factors associated with mortality in case of Pneumonia due to Stenotrophomonas Maltophilia. Secondary objectives were to describe factors associated with morbidity of Pneumonia due to Stenotrophomonas Maltophilia (duration of mechanical ventilation, ICU length of stay), and to report the characteristics of critically ill patients presenting Pneumonia due to Stenotrophomonas Maltophilia.

Early Aspiration Pneumonia is a frequent and dreadful complication in survivors of cardiac arrest. Therapeutic Hypothermia widely used in Intensive Care Unit for its benefice on post cardiac arrest syndrome may otherwise hide signs of early pneumonia that may occur without use of a reliable screening biological marker. The goal is to assess the diagnostic accuracy of bronchial alpha amylase measure to predict a risk of early aspiration pneumonia in patients successfully resuscitated after out-of-hospital cardiac arrest. In this prospective non interventional study we included patients resuscitated after cardiac arrest and treated with Targeted Temperature Management (TTM). A distal bronchoalveolar lavage using specific display (Combi-Cath) was executed immediately after admission for each patient with both biochemic and bacteriological analysis including dosage of bronchial salivary alpha amylase. Urea was used as a marker of dilution in the measure of bronchial and plasmatic alpha amylase. Aspiration pneumonia diagnosis was established with clinical and biological criteria. On this basis we intended to determine a threshold measure of alpha amylase predicting occurrence of aspiration pneumonia and allowing a guidance in antibiotherapy prescription. Sensibility and Specificity of this technique were determined.

Secondary bacterial influenza pneumonia caused by Panton-Valentine Leukocidin Positive Staphylococcus aureus is a rare complication but with poor prognosis. This pathology seems to affect young patients (20-40 years) without any medical history. Since the influenza pandemic of 2009, this complication is more and more mentioned, sought and diagnosed. However, the literature is poor, consisting of case reports, experimental studies on murine models, and low-power studies. The main objective is to evaluate the mortality in intensive care units of patients post-influenza bacterial pneumonia due to a Panton-Valentine Leukocidin positive Staphylococcus aureus

The investigators compare two strata of vaccinated patients: those recently vaccinated and those vaccinated more than two years ago. The primary objective is to compare pneumonia rates between the groups. As exploratory objectives, the investigators will describe the anti-pneumococcal antibody titers in hemodialysis patients as a function of time since vaccination, and determine factors influencing antibody kinetics. Further exploratory objectives investigate the relationship between antibody titers and the incidence of pneumonia in hemodialysis patients and extrapolate a possible cut-off for protection from pneumonia.

The infection is a major risk to hospitalized patients, especially those admitted to the Intensive Care Unit (ICU) and an unfavorable factor in the outcome of critically ill patients, increasing costs and prolonging hospitalization hospitalar. The ventilator-associated pneumonia (PAV) is considered the most prevalent nosocomial infection in the ICU, occurring in 9% to 68% of patients with prosthetic ventilatória.Due to the high rate of PAV and mortality related to it, is very important both prescription and administration of antibiotics correctly, as deescalation or escalation according the result of cultures.Therefore, the objectives of this study is assess if whether the antibiotic prescribed of ventilator-associated pneumonia following the orientation of literature. Will also be assessed the rate of PAV in patients critically ill adults, the main microorganisms responsible by PAV and determining antimicrobial susceptibility.

The goal of this study is to investigate acute respiratory distress syndrome (ARDS) and septic lung with positron emission tomography (PET) imaging and to examine the distribution of inflammation, as measured by neutrophil metabolic activity.
