pulmicort and Birth-Weight

We investigated the effect of an aerosolized corticosteroid (budesonide) on the oxygen requirement of infants at high risk for developing chronic lung disease (CLD) in a randomized, double-blind study. The study objective was to attain a 30% decrease in FiO2 levels in the budesonide treatment group after 14 d of therapy. Thirty very low birthweight (VLBW) infants (median (range)) gestational age 26 wk (23-29) and birthweight 805 g (525-1227) were randomized. Inclusion criteria were mechanical ventilation on day 6 of life, or if extubated on nasal continuous positive airway pressure with FiO2 > or = 0.3. The budesonide (Pulmicort) dose was 500 microg bid, or placebo. The aerosol was delivered with a dosimetric jet nebulizer, with variable inspiratory time and breath sensitivity. Inhalations were started on day 7 of life. Twenty-seven patients completed the study. A significant lowering of the FiO2 levels at 21 d of life was not detected. Infants who received budesonide were more often extubated during the study period (7/8 vs 2/9) and had a greater relative change from baseline in their oxygenation index (budesonide decreased 26% vs placebo increased 60%). Subsequent use of intravenous dexamethasone or inhaled budesonide in the treatment group was significantly less. All patients required O2 supplementation on day 28 of life. At 36 wk postconceptual age, 61% of infants in the budesonide group needed supplemental O2 as opposed to 79% in the placebo group. No side effects on growth or adrenal function were observed.. We conclude that inhaled budesonide aerosol via dosimetric jet nebulizer started on day 7 of life for infants at high risk for developing CLD decreases the need for mechanical ventilation similar to intravenous dexamethasone, but without significant side effects.

Initial trials of lung-targeted budesonide (0.25 mg/kg) in surfactant to prevent bronchopulmonary dysplasia (BPD) in premature infants have shown benefit; however, the optimal safe dose is unknown.. Dose-escalation study of budesonide (0.025, 0.05, 0.10 mg/kg) in calfactatant in extremely low gestational age neonates (ELGANs) requiring intubation at 3-14 days. Tracheal aspirate (TA) cytokines, blood budesonide concentrations, and untargeted blood metabolomics were measured. Outcomes were compared with matched infants receiving surfactant in the Trial Of Late SURFactant (TOLSURF).. Twenty-four infants with mean gestational age 25.0 weeks and 743 g birth weight requiring mechanical ventilation were enrolled at mean age 6 days. Budesonide was detected in the blood of all infants with a half-life of 3.4 h. Of 11 infants with elevated TA cytokine levels at baseline, treatment was associated with sustained decrease (mean 65%) at all three dosing levels. There were time- and dose-dependent decreases in blood cortisol concentrations and changes in total blood metabolites. Respiratory outcomes did not differ from the historic controls.. Budesonide/surfactant had no clinical respiratory benefit at any dosing levels for intubated ELGANs. One-tenth the dose used in previous trials had minimal systemic metabolic effects and appeared effective for lung-targeted anti-inflammatory action.

The prevalence of bronchial asthma is 4-8% among pregnant women. The complications, which threaten the asthmatic pregnancies according to the literature, are the following: spontaneous abortion, diabetes mellitus, caesarean delivery, pre-eclampsia, low gestational weight, neonatal icterus.. The aim of the study was a retrospective analysis of the data of asthmatic pregnant patients managed between 2000 and 2004, with a special consideration on the treatment and gynecologic complications.. The data of 53 persistent asthmatic patients--who had already undergone delivery--were collected. All of them were treated according to the guidelines issued in 2000 by the American College of Allergy, Asthma and Immunology and the American College of Obstetricians and Gynecologists: the inhalative corticosteroid budesonide, the long-acting beta-agonist formoterol or salmeterol and the short-acting beta-agonist terbutaline were used.. The mean peak expiratory flow of the asthmatic pregnant patients was 71 +/- 16% of predicted, and the mean partial arterial oxygen tension 96 +/- 9 mmHg (means +/- SE). 10 of the 53 patients had cesarean delivery, 3 developed pre-eclampsia, 1 diabetes mellitus. The mean gestational age was 38.84 +/- 2.17 weeks and the weight of newborns 3132 +/- 604 g. The hospitalization was prolonged due to the infants' hyperbilirubinaemia in 3 cases. No congenital malformations or spontaneous abortions were detected.. Based on the results of this retrospective study it can be concluded, that bronchial asthma slightly decreases the weight of newborns. The appropriate treatment of asthma during pregnancy resulted that the prevalence of gynecologic complications did not exceed the prevalence observed in the normal population--without increasing the risk of congenital malformations.

Inhaled corticosteroids are recommended as first-line therapy for pregnant women with moderate to severe asthma, although the effects on pregnancy outcome are uncertain. A low compliance with the recommendations might lead to inadequate control of asthma, which has been associated with adverse outcomes both for the mother and the infant.. To investigate whether the reported use of inhaled budesonide (Pulmicort) during pregnancy influences birth outcome.. Data were derived from the Swedish Medical Birth Register, which includes 99% of births in Sweden. During 1995 to 1998, 293,948 newborn infants were identified. Pregnancy outcomes were compared for mothers in Sweden reporting asthma medication usage with those reporting no asthma medication usage.. The 2,968 mothers who reported use of inhaled budesonide during early pregnancy gave birth to infants of normal gestational age, birth weight, and length, with no increased rate of stillbirths or multiple births. The rate of caesarean births was higher among mothers who used asthma medication during their pregnancy than among the control group.. The use of inhaled budesonide in Sweden is not linked with any clinically relevant effects associated with pregnancy outcome.

Acute asthma during pregnancy is potentially dangerous to the fetus. The aim of this study was to investigate the effect of an acute attack of asthma during pregnancy on the course of pregnancy or delivery, or the health of the newborn infant, and to identify undertreatment as a possible cause of the exacerbations.. Five hundred and four pregnant asthmatic subjects were prospectively followed and treated. The data on 47 patients with an attack of asthma during pregnancy were compared with those of 457 asthmatics with no recorded acute exacerbation and with 237 healthy parturients.. Of 504 asthmatics, 177 patients were not initially treated with inhaled corticosteroids. Of these, 17% had an acute attack compared with only 4% of the 257 patients who had been on inhaled anti-inflammatory treatment from the start of pregnancy. There were no differences between the groups as to length of gestation, length of the third stage of labour, or amount of haemorrhage after delivery. No differences were observed between pregnancies with and without an exacerbation with regard to relative birth weight, incidence of malformations, hypoglycaemia, or need for phototherapy for jaundice during the neonatal period.. Patients with inadequate inhaled anti-inflammatory treatment during pregnancy run a higher risk of suffering an acute attack of asthma than those treated with an anti-inflammatory agent. However, if the acute attack of asthma is relatively mild and promptly treated, it does not have a serious effect on the pregnancy, delivery, or the health of the newborn infant.
