Active clinical trials for "Acute Lung Injury"

RAGE, the receptor for advanced glycation end products, is a novel marker of alveolar epithelial type I cell injury, and soluble RAGE (sRAGE) is elevated in the plasma and in the pulmonary edema fluid from patients with ALI/ARDS. Few data are available about the influence of ventilatory interventions on levels of sRAGE in the setting of ALI/ARDS. The purpose of this prospective monocentric randomized controlled cross-over study is to describe the effects of a recruitment maneuver (RM) on plasma sRAGE levels during diffuse ARDS.

This study evaluates the use of nebulized hypertonic saline (aerosolized salt water) as a preventive treatment for post-traumatic acute lung injury (ALI). Both animal and human research indicate that aerosolized salt water might help reduce harmful inflammation with minimal risks.

Neurally-Adjusted Ventilatory Assist (NAVA) is a ventilatory mode that uses the electrical activity of the diaphragm to control the mechanical ventilator, offering inspiratory assistance in proportion to respiratory effort to patients who need artificial ventilatory support. It has been shown to improve the interaction between the patient and the mechanical ventilator in several clinical situations, but no previous studies have tried to use it for patients with a severe type of respiratory insufficiency, called Acute Respiratory Distress Syndrome (ARDS). Patients with ARDS benefit from a mechanical ventilatory strategy that includes low inspiratory volumes (tidal volumes) and limited airway pressures, but the application of such strategy frequently requires high levels of sedation. The investigators' hypothesis is that NAVA can be used for patients with ARDS, and that it will not be associated with excessive tidal volumes or elevated airway pressures.

In order to identify the effect of noninvasive positive pressure ventilation (NPPV) on decreasing inflammatory response, improving the pathophysiological manifestation and reducing the morbidity and mortality in the moderate acute respiratory distress syndrome (ARDS) patients, the investigators conduct this clinical trial comparing NPPV with invasive mechanical ventilation in more than twenty ICUs in China.

The purpose of this study is to evaluate the effect of lung recruitment maneuver in patients with early ALI/ARDS

This is an early phase (Phase IIa), randomized, double-blind, parallel group, multi-centre study for subjects with trauma (physical injury) who are at risk for developing Acute Lung Injury (ALI) or Acute Respiratory Distress Syndrome (ARDS). The primary purpose of the study is to evaluate the safety and tolerability of SB-681323, which is a potent, selective inhibitor of p38 alpha (MAPK) (prevents inflammation of tissue), in comparison to a placebo.

The central purpose of this proposal is to study the short-term effects of sedation with sympatholysis, using α2 adrenergic agent Dexmedetomidine, on sleep and inflammation in critically ill patients with Acute Lung Injury and Acute Respiratory Disorder Syndrome (ALI/ARDS). An additional objective is to determine the effect of Dexmedetomidine sedation on the in-vitro production of sleep-modulating inflammatory cytokines by peripheral blood mononuclear cells of critically ill patients with ALI/ARDS.

Acute lung injury (ALI) is a common, life-threatening complication among pediatric leukemia and lymphoma and hematopoietic stem cell transplant (HSCT) recipients. Although these children represent a relatively small and unique patient population, they account for the largest proportion of deaths of all pediatric diseases. The long-term goal of this project is to improve outcomes among these patients. Recently, the intratracheal administration of calfactant has resulted in decreased mortality among children with ALI including promising results among children with cancer and following HSCT. Consequently, the primary specific aim of this study is to assess the effect of calfactant on intensive care (PICU) survival among pediatric leukemia and lymphoma and HSCT patients with ALI. Secondary aims include assessment of the effect of calfactant on oxygenation and on the length of mechanical ventilation, PICU stay, and hospital stay. Calfactant therapy has been found to be of benefit in acute lung injury in the overall pediatric population by improving oxygenation and decreasing mortality. These findings, in conjunction with recent subgroup analysis in which calfactant therapy appeared to improve outcomes in immunocompromised children provide the rationale for assessing calfactant therapy in this patient population.

This is a prospective, randomized (1:1), double-blind, multi-center, Phase II clinical study to test the safety and efficacy of a recombinant chimeric anti-tissue factor antibody (ALT-836) versus placebo in patients with sepsis and acute lung injury/acute respiratory distress syndrome (ALI/ARDS). This study was divided into two parts and the first part of the study has been completed. In the first part of the study, sixty patients were randomized at a 1:1 ratio to receive one dose of the study drug or placebo. In the second part of the study, ninety patients will be randomized at a 1:1 ratio to receive a multi-dose treatment regimen of single doses every 72 hours up to a maximum of 4 doses of the study drug or placebo, provided there are no safety concerns.

This study will examine the safety of an experimental medication called Poly-ICLC, developed for preventing or reducing the severity of infections from influenza and other viruses acquired through the nose, mouth and lungs. The study is divided into two parts, in which Poly-ICLC is tested at different dose levels. Healthy people between 18 and 70 years of age who have no chronic medical problems may be eligible for this study. Participants undergo the following procedures: Part I Up to 7 days before Poly-ICLC administration: Medical history, physical examination and blood tests. Day 1: Nasal wash and Poly-ICLC administration. A small amount of salt water is placed into the front of the nose and then suctioned out. Poly-ICLC is then squirted into each nostril, one after the other, at a dose of 0.25, 0.5 or 1 mg. A small number of subjects are given a placebo (a solution with no active ingredient.) Subjects are observed in the clinic for 30 minutes after treatment. Day 2: Subjects receive a second nasal wash and repeat blood tests. They keep a diary card for 1 week, recording any drug side effects. Day 5: Subjects have repeat blood tests and a review of their diary card. The keep a diary card for another 3 weeks. Day 12: Subjects are contacted by phone to review their diary card. Day 28: Subjects are contacted by phone to review their diary card. Part II Up to 7 days before Poly-ICLC administration: Medical history, physical examination and blood tests. Day 1: Nasal wash and Poly-ICLC administration. Same as above for Part I participants. Day 3: Subjects receive a second dose of medication and are observed again for 30 minutes. Day 4: Subjects receive a second nasal wash and repeat blood tests. They keep a diary card for 1 week, recording any drug side effects. Day 7: Subjects have repeat blood tests and a review of their diary card. The keep a diary card for another 3 weeks. Day 14: Subjects are contacted by phone to review their diary card. Day 28: Subjects are contacted by phone to review their diary card.
