Natural Surfactant Combined with Beclomethasone Decreases Lung Inflammation in the Preterm Lamb

ثبت نشده
چکیده

Background: Natural surfactant combined with beclomethasone decreases pulmonary oxidative stress in preterm lambs with respiratory distress syndrome (RDS). Objectives: To test the hypothesis that this occurs through a decrease in pulmonary inflammation. Methods: Preterm lambs received 200 mg/kg of natural surfactant or 200 mg/kg of natural surfactant combined with 400 or 800 g/kg of beclomethasone. Interleukin 8 (IL-8) and macrophage migration inhibitory factor (MIF) were assayed in bronchial aspirate samples and lung mechanics were evaluated. Results: IL-8 increased in all the groups, but the increase was lower in the groups treated with surfactant plus 400 and 800  g/kg of beclomethasone. MIF decreased in the surfactant group, did not vary in the surfactant plus 400  g/kg beclomethasone group, and decreased in the surfactant plus 800  g/kg beclomethasone group. MIF concentration was higher in the Received: December 13, 2010 Accepted after revision: April 29, 2011 Published online: September 15, 2011 Carlo Dani, MD Division of Neonatology, Careggi University Hospital University of Florence School of Medicine Viale Morgagni, 85, IT–50141 Firenze (Italy) Tel. +39 055 7947 428, E-Mail cdani @ unifi.it © 2011 S.

Optimization of Variable Ventilation for Physiology, Immune Response and Surfactant Enhancement in Preterm Lambs

Preterm infants often require mechanical ventilation due to lung immaturity including reduced or abnormal surfactant. Since cyclic stretch with cycle-by-cycle variability is known to augment surfactant release by epithelial cells, we hypothesized that such in vivo mechanotransduction improves surfactant maturation and hence lung physiology in preterm subjects. We thus tested whether breath-by-b...

Intra-amniotic LPS and antenatal betamethasone: inflammation and maturation in preterm lamb lungs.

The proinflammatory stimulus of chorioamnionitis is commonly associated with preterm delivery. Women at risk of preterm delivery receive antenatal glucocorticoids to functionally mature the fetal lung. However, the effects of the combined exposures of chorioamnionitis and antenatal glucocorticoids on the fetus are poorly understood. Time-mated ewes with singleton fetuses received an intra-amnio...

SP-B and SP-C Containing New Synthetic Surfactant for Treatment of Extremely Immature Lamb Lung

Although superiority of synthetic surfactant over animal-driven surfactant has been known, there is no synthetic surfactant commercially available at present. Many trials have been made to develop synthetic surfactant comparable in function to animal-driven surfactant. The efficacy of treatment with a new synthetic surfactant (CHF5633) containing dipalmitoylphosphatidylcholine, phosphatidylglyc...

Biophysical interaction between corticosteroids and natural surfactant preparation: implications for pulmonary drug delivery using surfactant a a carrier.

Intratracheal administration of corticosteroids using a natural pulmonary surfactant as a delivery vehicle has recently received significant attention in hopes of treating premature newborns with or at high risk for chronic lung disease. As a new practice, both the surfactant preparation used as the carrier and the corticosteroid delivered as the anti-inflammatory agent, and their mixing ratios...
