Nitric Oxide Therapy for Acute Chest Syndrome in Sickle Cell Disease Children

2014-08-27 03:15:06 | BioPortfolio

Summary

Acute chest syndrome is a severe sickle cell disease complication in children requiring blood transfusion therapy to prevent acute respiratory failure and death. Nitric oxide is a potent vasodilator that could reverse pulmonary vascular occlusion and restore normal oxygenation. The randomized trial will test that hypothesis.

Description

Acute chest syndrome is a severe sickle cell disease complication in children requiring blood transfusion therapy to prevent acute respiratory failure and death. Nitric oxide is a potent vasodilator that could reverse pulmonary vascular occlusion and restore normal oxygenation. The randomized trial will test that hypothesis in a prospective randomized double-blind placebo controlled study. 50 children in two years will be included: 25 in each arm.

Nitric oxide by inhalation INOMAX, Placebo

Effect of Inhaled Nitric Oxide in Acute Chest Syndrome (INOSTA Study)

Acute chest syndrome (ACS) is a frequent and potentially life-threatening pulmonary illness. It is a complication of sickle cell disease and is the leading cause of death from this disease...

Registry Evaluating Premature and Term-Near-Term Neonates With Pulmonary Hypertension Receiving Inhaled Nitric Oxide

This is a multicenter, prospectively defined, observational registry study evaluating the use of inhaled nitric oxide (INOMAX) in 84 Premature (P) neonates (at least 27 weeks but less than...

Comparison of Inhaled Nitric Oxide Versus Oxygen in Patient Reactivity During Acute Pulmonary Vasodilator Testing

A minimum of 100 patients will be enrolled in the study to demonstrate which diagnostic treatment (oxygen or nitric oxide) is most capable of identifying patients with a reactive pulmonary...

Effects of Inhaled Nitric Oxide in the Treatment of Acute Hypoxemic Respiratory Failure (AHRF) in Pediatrics

The purpose of this study is to determine the effect of nitric oxide for inhalation on the duration of mechanical ventilation in pediatric patients with AHRF.

Arginine Treatment of Acute Chest Syndrome (Pneumonia) in Sickle Cell Disease Patients

This is a study to determine if oral arginine will increase nitric oxide in sickle cell disease (SCD) patients with acute chest syndrome (ACS). It will also assess the effects of arginine ...

Acute effects of hypertonic saline inhalation on nitric oxide pulmonary diffusing capacity in healthy adults.

We investigated acute effects of inhalation of hypertonic saline solution (HSS) and oxygen (O, control exposure) on pulmonary diffusing capacity for nitric oxide (DLNO) and carbon monoxide (DLCO). In ...

Pharmacological preconditioning with inhaled nitric oxide (NO): Organ-specific differences in the lifetime of blood and tissue NO metabolites.

Endogenous nitric oxide (NO) may contribute to ischemic and anesthetic preconditioning while exogenous NO protects against ischemia-reperfusion (I/R) injury in the heart and other organs. Why those be...

Acute chest syndrome in sickle cell disease.

The acute chest syndrome is a frequent complication in patients with sickle cell disease. It results from the occlusion of pulmonary capillaries and complex pathophysiological mechanisms. The diagnosi...

Chlorine gas inhalation manifesting with severe acute respiratory distress syndrome successfully treated by high-volume hemofiltration: A case report.

There have been occasional reports of respiratory dysfunction associated with acute chlorine gas inhalation. However, management of acute chlorine-related inhalation injury is largely empirical, suppo...

The assessment and management of chest pain in primary care: A focus on acute coronary syndrome

Chest pain is a common presentation and diagnosis can be challenging. There are many causes for chest pain, including life-threatening conditions such as acute coronary syndrome (ACS), which can prove...

Medical and Biotech [MESH] Definitions

A diverse group of agents, with unique chemical structures and biochemical requirements, which generate NITRIC OXIDE. These compounds have been used in the treatment of cardiovascular diseases and the management of acute myocardial infarction, acute and chronic congestive heart failure, and surgical control of blood pressure. (Adv Pharmacol 1995;34:361-81)

A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.

An NADPH-dependent enzyme that catalyzes the conversion of L-ARGININE and OXYGEN to produce CITRULLINE and NITRIC OXIDE.

Respiratory syndrome characterized by the appearance of a new pulmonary infiltrate on chest x-ray, accompanied by symptoms of fever, cough, chest pain, tachypnea, or DYSPNEA, often seen in patients with SICKLE CELL ANEMIA. Multiple factors (e.g., infection, and pulmonary FAT EMBOLISM) may contribute to the development of the syndrome.

A CALCIUM-dependent, constitutively-expressed form of nitric oxide synthase found primarily in NERVE TISSUE.
