pentetic acid and Cough

pentetic acid has been researched along with Cough in 1 studies

Pentetic Acid: An iron chelating agent with properties like EDETIC ACID. DTPA has also been used as a chelator for other metals, such as plutonium.

Cough: A sudden, audible expulsion of air from the lungs through a partially closed glottis, preceded by inhalation. It is a protective response that serves to clear the trachea, bronchi, and/or lungs of irritants and secretions, or to prevent aspiration of foreign materials into the lungs.

Trial Outcomes

Breathlessness, Cough and Sputum Scale (BCSS) - Exacerbations

"Self-reported symptom severity, used as a daily patient diary. The BCSS is a 12 point self-reported symptom severity score, consisting of 3 sections concerning how much difficulty the subject is having with breathing; subjective cough symptoms and trouble caused by sputum, each scoring between 0-4, combining to a total score of 0-12 (higher=worse). This scale is validated for daily use in Chronic Obstructive Pulmonary Disease (COPD)(21).~An exacerbation was defined as an increase in BCSS>1 with ≥5 days preceding stability." (NCT01952470)
Timeframe: Daily up to 3 months.

Lung Clearance Index 2% (LCI2%)

"A measure of ventilation inhomogeneity as measured during multiple breath washout (MBW) of inert tracer gases. It has been shown that this test is a potentially more sensitive measure of peripheral airway obstruction than regular spirometry in short term (4 week) mucolytic interventional studies in pediatric Cystic Fibrosis (CF)(17-18). This test would be performed within the respiratory physiology lung function laboratory on site at all assessment points, by an assessor who is blinded to group allocation for follow up data collection.~Conventionally used primary endpoints in this population, such as regular spirometry(3), may be unable to detect between group differences without large sample sizes and long treatment durations. Based on current evidence from non-lung transplant populations, LCI has been able to show short-term change, whereas regular spirometry has not shown change(17-18)." (NCT01952470)

Multiple Breath Washout (MBW)

"Multiple breath washout is a sensitive measure of respiratory function performed with the subject in a seated position, breathing a fixed tidal volume (1L) of inert gas (nitrogen) from functional residual capacity (FRC) via mouthpiece.~Two common outcomes of MBW are Sacin, a measure of gas mixing at the diffusion front, or acinar entrance in the airways, and Scond, in the proximal, conductive zones. An increase in either Sacin or Scond represents an increase in ventilation heterogeneity (deterioration). Both increase with age, normal values are non-zero between 0-0.25(Sacin) and 0-0.1(Scond)."
