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 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. 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. 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. Postnatal corticosteroid therapy is controversial. The aim of this study was to determine the short-term effects of low-dose dexamethasone treatment among chronically ventilator-dependent neonates.
                Very preterm (gestational age: <28 weeks) or extremely low birth weight (birth weight: <1000 g) infants who were ventilator dependent after the first 1 week of life were eligible and were assigned randomly to receive masked dexamethasone (0.89 mg/kg over 10 days) or saline placebo. Data on ventilator and oxygen requirements and deaths were recorded.
                Seventy infants were recruited from 11 centers, at a median age of 23 days. More infants were extubated successfully by 10 days of treatment in the dexamethasone group (60%, 21 of 35 patients) than in the control group (12%, 4 of 34 patients) (odds ratio [OR]: 11.2; 95% confidence interval [CI]: 3.2-39.0). Ventilator and oxygen requirements improved substantially, and the duration of intubation was shorter. There was little evidence for a reduction in either the mortality rate (dexamethasone group: 11%; control group: 20%; OR: 0.52; 95% CI: 0.14-1.95) or the rate of oxygen dependence at 36 weeks (dexamethasone group: 85%; control group: 91%; OR: 0.58; 95% CI: 0.13-2.66). There were no obvious effects of low-dose dexamethasone on blood glucose concentrations, blood pressure, or other complications. No infant experienced intestinal perforation.
                Low-dose dexamethasone treatment after the first 1 week of life clearly facilitates extubation and shortens the duration of intubation among ventilator-dependent, very preterm/extremely low birth weight infants, without any obvious short-term complications. Combined with recent evidence that infants at very high risk of bronchopulmonary dysplasia may benefit in the long term, our study reopens debate regarding the role of low-dose, late postnatal, corticosteroid therapy. 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. 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 purpose of this study was to evaluate the effect of early administration of dexamethasone on the incidence of chronic lung disease (CLD) in high risk preterm infants and to evaluate the side effects of the early steroid administration.
                Randomised clinical trial.
                Neonatal intensive care unit.
                50 infants at high risk of CLD were randomly assigned after 72 h of life to the dexamethasone group (n = 25) or to the control group (n = 25). The treated infants received dexamethasone intravenously from the 4th day of life for 7 days (0.5 mg/kg per day for the first 3 days, 0.25 mg/kg per day for the next 3 days and 0.125 mg/kg per day on the 7th day). The control group received no steroid treatment.
                The incidence of CLD at 28 days of life and at 36 weeks' postconceptional age was significantly lower in the dexamethasone group than in the control group (p < 0.001). Moreover, infants in the dexamethasone group remained intubated and required oxygen therapy for a shorter period than those in the control group (p < 0.001). Hyperglycaemia, hypertension, growth failure and mainly hypertrophy of the left ventricle were the transient side effects associated with early steroid administration.
                Early dexamethasone administration may be useful in preventing CLD, but its use should prudently be restricted to preterm infants at high risk of CLD. The objective of the study was to determine the efficacy and side effects of corticosteroid therapy for pregnant women with severe preeclampsia in the prevention of respiratory distress syndrome in their premature neonates.
                A prospective double-blind randomized trial enrolled 218 pregnant women with severe preeclampsia and gestational age between 26 and 34 weeks. One hundred ten received betamethasone (12 mg administered intramuscularly, repeated after 24 hours and then once a week) and 108 received placebo. Relative risks and 95% confidence intervals of respiratory distress syndrome and other neonatal and maternal complications were calculated for corticosteroid use.
                Frequency of respiratory distress syndrome was significantly reduced in the corticosteroid group (23%) with respect to the placebo group (43%), with a relative risk of 0.53 (95% confidence interval 0.35-0. 82). Relative risks of intraventricular hemorrhage, patent ductus arteriosus, and perinatal infection were significantly decreased in the corticosteroid group: 0.35 (95% confidence interval 0.15-0.86), 0.27 (95% confidence interval 0.08-0.95), and 0.39 (95% confidence interval 0.39-0.97), respectively. There was no significant difference in the frequency of stillbirth, but the neonatal mortality rate was lower in the corticosteroid group (14%) than in the placebo group (28%), with a relative risk of 0.5 (95% confidence interval 0.28-0.89). There was increased risk of gestational diabetes but of no other maternal complication after corticosteroid therapy, and mean blood pressures were similar in the 2 groups.
                Antenatal corticosteroid therapy with betamethasone for acceleration of fetal lung maturity is a safe and efficient treatment in patients with severe preeclampsia at between 26 and 34 weeks' gestation.
The benefits of early postnatal corticosteroid treatment (≤ 7 days), particularly dexamethasone, may not outweigh the known or potential adverse effects of this treatment. Although early corticosteroid treatment facilitates extubation and reduces the risk of chronic lung disease and patent ductus arteriosus, it causes short-term adverse effects including gastrointestinal bleeding, intestinal perforation, hyperglycaemia, hypertension, hypertrophic cardiomyopathy and growth failure. Long-term follow-up studies report an increased risk of abnormal neurological examination and cerebral palsy. However, the methodological quality of the studies determining long-term outcomes is limited in some cases; the surviving children have been assessed predominantly before school age, and no study has been sufficiently powered to detect important adverse long-term neurosensory outcomes. There is a compelling need for the long-term follow-up and reporting of late outcomes, especially neurological and developmental outcomes, among surviving infants who participated in all randomised trials of early postnatal corticosteroid treatment. Hydrocortisone in the doses and regimens used in the reported RCTs has few beneficial or harmful effects and cannot be recommended for prevention of CLD.
