In order to assess the efficacy of a combination of systemic and nebulized corticosteroids in reducing the incidence and severity of chronic lung disease (CLD) in very low birthweight (VLBW) infants, 60 ventilator-dependent infants < or = 1500 g were randomly assigned to receive either steroids or placebo as of 7 d. The steroid group (n = 30, GA = 25.8 +/- 1.6 weeks, BW = 731 +/- 147 g) received systemic dexamethasone for 3 d, followed by nebulized budesonide for 18 d. Control infants (n = 30, GA = 25.9 +/- 1.8 weeks, BW = 796 +/- 199 g) received systemic and inhaled saline. Steroid-treated infants required less ventilatory support between 9 and 17 d (p < 0.01), and had greater lung compliance at 10 d (p = 0.01), but not subsequently. CLD incidence at 36 weeks was 45.5% vs 56.0% in controls, and fewer steroid-treated infants required dexamethasone rescue (23.3% vs 56.7%, p = 0.017). Survival to discharge was similar (73.3% vs 83.3%), as were the durations of mechanical ventilation, supplemental oxygen use, and hospitalization. Tracheal effluent elastase/albumin ratios and serum cortisol values did not differ between groups, and no adverse effects were noted. We conclude that early dexamethasone administration was associated with improved pulmonary function, which was not sustained with nebulized budesonide. However, the steroid regimen studied reduced the need for dexamethasone rescue in infants with CLD. To investigate the therapeutic efficacy of inhaled fluticasone propionate, started on day 1 of age, on ventilated preterm infants with respiratory distress syndrome.
                Starting within 24 hours of age, ventilated preterm infants (gestation < 32 weeks, birthweight < 1.5 kg) with respiratory distress syndrome were given a 14 day course (two puffs, 12 hourly) of either fluticasone propionate (250 microg/puff) (group 1, n=27) or placebo (group 2, n=26) with a metered dose inhaler-spacer device. Response to treatment was assessed by the rate of successful extubation by days 7 and 14 of age, changes in respiratory system mechanics, death, occurrence of chronic lung disease, and other neonatal complications.
                More infants in the treatment group were successfully extubated by 14 days of age than those in the placebo group (17/27 vs 8/26; p = 0.038). The treated infants also showed a more significant improvement in respiratory system compliance during the first 14 days of life. The two groups, however, did not differ significantly in their need for systemic steroids after day 14 of age, death, or the occurrence of chronic lung disease. The treatment was not associated with any increase in neonatal complications, including those attributable to steroid induced side effects.
                These results provide preliminary evidence that early treatment with inhaled corticosteroids may be beneficial to ventilated preterm infants with respiratory distress. Further study of its use in a large scale randomised trial is warranted. To study the effect of highdose prednisone on intracranial pressure (ICP), cranial computed tomographic (CT) findings, and clinical outcome in young children with moderate to severe tuberculous meningitis (TBM).
                Prospective, controlled, randomized study.
                Continuous lumbar, cerebrospinal fluid pressure monitoring and contrasted CT scanning were performed in 141 consecutive children with TBM at admission. All children were then randomly allocated to a nonsteroid group (71 children) or a steroid group (70 children) who received prednisone (first 16 children, 2 mg/kg per day; next 54 children, 4 mg/kg per day) for the first month of treatment. ICP monitoring and CT scanning were repeated regularly, and clinical outcome was assessed after 6 months of antituberculosis treatment.
                No statistically significant difference in ICP or the degree of hydrocephalus (as demonstrated by CT scan) was found between the steroid and nonsteroid groups after the first month of treatment. Basal ganglia infarcts developed in 16% of children in the steroid group and 24% in the nonsteroid group during the first month of treatment. Neither this incidence nor the eventual size of infarcts present at admission differed significantly between the two treatment groups. Single or multiple tuberculomas were seen on the first CT scans of 7 children (5%), whereas tuberculomas developed in 11 children (8%) at treatment. Both the response of the tuberculomas to treatment and the incidence of new tuberculomas were significantly improved by steroid therapy. Basal enhancement was also significantly less in the steroid group after 1 month of treatment. Steroids lowered mortality in stage III TBM significantly. Similarly, more surviving children in the steroid group had IQs of greater than 75 than did the those in the nonsteroid group. No significant difference was found in the incidence of motor deficit, blindness, or deafness.
                Corticosteroids significantly improved the survival rate and intellectual outcome of children with TBM. Enhanced resolution of the basal exudate and tuberculomas by steroids was shown by serial CT scanning. Corticosteroids did not affect ICP or the incidence of basal ganglia infarction significantly. To compare early (<3 days) with late (>15 days) steroid therapy and dexamethasone with inhaled budesonide in very preterm infants at risk of developing chronic lung disease.
                Five hundred seventy infants from 47 neonatal intensive care units were enrolled. Criteria for enrollment included gestational age <30 weeks, postnatal age <72 hours, and need for mechanical ventilation and inspired oxygen concentration >30%. Infants were randomly allocated to 1 of 4 treatment groups in a factorial design: early (<72 hours) dexamethasone, early budesonide, delayed selective (>15 days) dexamethasone, and delayed selective budesonide. Dexamethasone was given in a tapering course beginning with 0.50 mg/kg/day in 2 divided doses for 3 days reducing by half until 12 days of therapy had elapsed. Budesonide was administered by metered dose inhaler and a spacing chamber in a dose of 400 microg/kg twice daily for 12 days. Delayed selective treatment was started if infants needed mechanical ventilation and >30% oxygen for >15 days. The factorial design allowed 2 major comparisons: early versus late treatment and systemic dexamethasone versus inhaled budesonide. The primary outcome was death or oxygen dependency at 36 weeks and analysis was on an intention-to-treat basis. Secondary outcome measures included death or major cerebral abnormality, duration of oxygen treatment, and complications of prematurity. Adverse effects were also monitored daily.
                There were no significant differences among the groups for the primary outcome. Early steroid treatment was associated with a lower primary outcome rate (odds ratio [OR]: 0.85; 95% confidence interval [CI]: 0.61,1.18) but even after adjustment for confounding variables the difference remained nonsignificant. Dexamethasone-treated infants also had a lower primary outcome rate (OR: 0.86; 95% CI: 0.62,1.20) but again this difference remained not significant after adjustment. For death before discharge, dexamethasone and early treatment had worse outcomes than budesonide and delayed selective treatment (OR: 1.42; 95% CI: 0.93,2.16; OR: 1.51; 95% CI: 0.99,2.30 after adjustment, respectively) with the results not quite reaching significance. Duration of supplementary oxygen was shorter in the early dexamethasone group (median: 31 days vs 40-44 days). Early dexamethasone was also associated with increased weight loss during the first 12 days of treatment (52 g vs 3 g) compared with early budesonide, but over 30 days there was no difference. In the early dexamethasone group, there was a reduced incidence of persistent ductus arteriosus (34% vs 52%-59%) and an increased risk of hyperglycemia (55% vs 29%-34%) compared with the other 3 groups. Dexamethasone was associated with an increased risk of hypertension and gastrointestinal problems compared with budesonide but only the former attained significance.
                Infants given early treatment and dexamethasone therapy had improved survival without chronic lung disease at 36 weeks compared with those given delayed selective treatment and inhaled budesonide, respectively, but results for survival to discharge were in the opposite direction; however, none of these findings attained statistical significance. Early dexamethasone treatment reduced the risk of persistent ductus arteriosus. Inhaled budesonide may be safer than dexamethasone, but there is no clear evidence that it is more or less effective. The aim of the study was to determine the feasibility, the cost and the effects of antenatal maternal corticosteroid treatment on preventing respiratory distress syndrome in premature neonates of our population.
                Between January, 1, 1998 and June, 31, 1999, 118 pregnant women at 26-34 weeks' gestation and at a high risk of premature delivery, were prospectively randomized in 2 groups: group 1 received intramusculary 24 mg of betamethasone (12 mg every 24 hours), group 2 didn't receive antenatal corticosteroids. At birth, premature neonates were systematically examined by a neonatologist.
                131 premature neonates were born (63 from group 1, 68 from group 2). The incidence and the degree of severity of respiratory distress syndrome, appeared substancially reduced (4.8% vs 27.9%) by the use of antenatal corticosteroids. Moreover, neonatal mortality due to respiratory distress syndrome was statistically less in group 1 than in group 2 (22.9% vs 57%). There was no significant difference in the occurrence of maternal or neonatal corticosteroid complications such as infection between treated group and control subjects. We estimated a potential annual savings of 21 thousands tunisian dinars, when the cost implications for antenatal corticosteroid therapy were estimated to 2 thousands tunisian dinars.
                Maternal administration of corticosteroids before preterm delivery results in a decrease in the incidence and severity of respiratory distress syndrome and a decrease in neonatal mortality rate among premature neonates born to treated versus untreated mothers at 26-34 weeks' gestation; added to an annual savings estimated to 21 thousands tunisian dinars. This study was carried out to examine the effect of antenatal corticosteroid therapy on pregnancies complicated by premature rupture of membranes (PROMs). For this purpose, 139 patients with a singleton pregnancy (27-34 weeks of gestation) complicated by PROMs were evaluated prospectively during the period January 1997 to February 1999 at two Jordanian military hospitals (Prince Rhashed and Prince Zaid). Patients were allocated into two groups; Group 1 included 72 patients treated with dexamethsone (24 mg divided into 4 doses 12 hours apart), and Group 2 which included 67 patients whoreceived no treatment (control group). All women were examined clinically and the diagnosis of PROMs was demonstrated using vaginal speculum, nitrazine paper examination and ultrasonography. All neonates were evaluated clinically, radiologically, and by laboratory investigations. Pearson's Chi-square and Fisher's exact tests were used to assess the significance of differences between the two study groups. Respiratory distress syndrome (RDS), necrotizing enterocolitis (NEC), intraventricular haemorrhage (IVH), and days of hospital stay were significantly reduced in premature infants of the corticosteroid treated women compared with the controls (p<0.04, p<0.04, p<0.04, and p<0.05, respectively). The perinatal mortality was significantly decreased among the corticosteroid treated group in the gestational subgroups 31-32 and 33-34 weeks (p<0.04), and in all birth weight subgroups (p<0.03). RDS was statistically a significant factor which resulted in increased perinatal mortality in the control group (p=0.02). Regarding the occurrence of postpartum endometritis there was a statistically significant increase among the corticosteroid treated group compared with the controls (p<0.04). Conclusion: Antenatal corticosteroid therapy in pregnancies complicated by PROMs has a positive influencing effect on premature infants between 31 and 34 weeks of gestation, decreasing significantly the perinatal morbidity and mortality. It should be used with particular relevance to the developing world where surfactant is not available or where neonatal intensive care units are lacking. Corticosteroids continue to be used by many physicians to treat infants with bronchiolitis. The aim of this study was to examine the short-term and long-term efficacy of oral corticosteroid therapy when added to beta2-agonists in infants with mild to moderate bronchiolitis (defined as the first episode of wheezing associated with low grade fever, rhinitis, tachypnea, and increased respiratory effort in a previously healthy infant during the winter months). Infants with mild to moderate bronchiolitis, were randomly assigned to receive either oral prednisone (2 mg/kg/day) or placebo for 3 days. All patients received nebulized albuterol q.i.d. during this period. Upon admission and after 3 days of therapy, a clinical score was assigned based on respiratory rate, use of accessory muscle, and the presence of wheeze. Oxygen saturation (SaO2) was also measured. On day 7, we inquired as to the well-being of each child. Two years later, the development of chronic respiratory symptoms was assessed. Thirty-eight infants were enrolled in the study; 20 received prednisone and 18 received placebo. Both groups were similar in terms of age, duration of illness prior to enrollment, pretrial medication use, clinical severity of bronchiolitis, history of atopy, and family history of atopy. After 3 and 7 days of treatment, both groups showed similar clinical improvement and there were no statistically significant differences between the two groups in the clinical score or in the SaO2. No major side effects were observed. Two years later, 32% of the infants continued to suffer from chronic respiratory symptoms, with a similar prevalence in both groups. We conclude that a 3-day course of oral corticosteroids is of no benefit to infants with mild to moderate bronchiolitis who are also treated with an inhaled beta2-agonist. Several reports indicate a decreased cortisol response to adrenocorticotropic hormone in preterm infants developing chronic lung disease and in preterm infants with refractory hypotension. Low-dose hydrocortisone (HC) may allow for beneficial effects.
                Our aim was to assess whether HC is able to increase survival without chronic lung disease.
                We performed a double-blind, randomized, placebo-controlled trial. Fifty mechanically ventilated infants (birth weight: 500-1,249 g) were randomized to receive treatment (HC 0.5 mg/kg/12 h for 9 days, then HC 0.5 mg/kg/24 h for 3 days) or placebo. Major outcome was survival without oxygen dependence at 36 weeks of postconceptional age (O(2)-free survival).
                The basic characteristics were similar between the two groups. O(2)-free survival was higher in the HC group (64 vs. 32%). The advantage was particularly evident among infants without antenatal steroids. The mortality rate was 16% in the HC group versus 40% in the control group (difference not significant). Hypotension after recruitment was reduced by HC (0 vs. 30%). The incidence of gastrointestinal perforation and other adverse effects was similar between the two groups.
                HC prophylaxis improved O(2)-free survival and early cardiocirculatory function in our population, without important short-term effects. The neurodevelopmental outcome will be assessed at 2 years.
                Copyright (c) 2007 S. Karger AG, Basel. The efficacy and safety of repeat doses of prenatal corticosteroids remains uncertain. Our aim was to establish whether repeat prenatal corticosteroids given to women at risk of preterm birth can reduce neonatal morbidity without harm.
                In this hospital-based study, 982 women who remained at risk of preterm birth at less than 32 weeks' gestation, 7 or more days after receiving a first course of prenatal corticosteroids, were randomly assigned to receive a repeat intramuscular dose of either 11.4 mg betamethasone (as Celestone Chronodose), or saline placebo. This was repeated every week the woman remained undelivered, at less than 32 weeks' gestation, and at risk of preterm birth. Primary outcomes were occurrence and severity of neonatal respiratory distress syndrome, use and duration of oxygen and mechanical ventilation, and weight, length, and head circumference at birth and hospital discharge. Statistical analyses were on an intention to treat basis. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN48656428.
                Fewer babies exposed to repeat corticosteroids had respiratory distress syndrome (33%vs 41%; relative risk 0.82, 95% CI 0.71-0.95, p=0.01) and fewer had severe lung disease (12%vs 20%; relative risk 0.60, 95% CI 0.46-0.79, p=0.0003) than those in the placebo group. In keeping with these benefits, babies exposed to repeat corticosteroids needed less oxygen therapy (p=0.03), and shorter duration of mechanical ventilation (p=0.01). Mean weight, length, and head circumference at birth and hospital discharge did not differ between treatment groups. Z-scores for weight (p=0.04) and head circumference (p=0.03) at birth were lower in the babies who received repeat corticosteroids although at the time of hospital discharge Z-scores did not differ between treatment groups (p=0.29 for weight, p=0.48 for head circumference).
                Exposure to repeat doses of antenatal corticosteroids reduces neonatal morbidity. Pending long-term outcome results, the short-term benefits for the babies in our study support the use of repeat doses of corticosteroids in women who remain at risk of very preterm birth 7 or more days after an initial course.
The benefits of late corticosteroid therapy may not outweigh actual or potential adverse effects. Although there continues to be concern about an increased incidence of adverse neurological outcomes in infants treated with postnatal steroids (see also review of "Early postnatal corticosteroids for preventing chronic lung disease in preterm infants"), this review of postnatal corticosteroid treatment for CLD initiated after seven days of age suggests that late therapy may reduce neonatal mortality without significantly increasing the risk of adverse long-term neurodevelopmental outcomes. However, the methodological quality of the studies determining the long-term outcome is limited in some cases; in some studies the surviving children have only been assessed before school age when some important neurological outcomes cannot be determined with certainty, and no study was sufficiently powered to detect increased rates of important adverse long-term neurosensory outcomes. Given the evidence of both benefits and harms of treatment, and the limitations of the evidence at present, it appears prudent to reserve the use of late corticosteroids to infants who cannot be weaned from mechanical ventilation and to minimise the dose and duration of any course of treatment.
