To assess the effectiveness of a "stress dose" of hydrocortisone for rescue treatment of refractory hypotension and adrenocortical insufficiency of prematurity in very low birth weight (VLBW) infants. We hypothesized that significantly more VLBW infants who were receiving dopamine > or =10 microg/kg per min could wean off vasopressor support 72 hours after treatment with hydrocortisone.
                A double-blind, randomized, controlled study was conducted in a university neonatal center. Forty-eight VLBW infants who had refractory hypotension and required dopamine > or =10 microg/kg per min were randomly assigned to receive a stress dose of hydrocortisone (1 mg/kg every 8 hours for 5 days; n = 24) or an equivalent volume of the placebo solution (isotonic saline; n = 24).
                The baseline clinical characteristics were similar between the groups. Serum cortisol concentrations were very low immediately before randomization in both groups of infants. Significantly more VLBW infants who were treated with hydrocortisone weaned off vasopressor support 72 hours after starting treatment. The use of volume expander, cumulative dose of dopamine, and dobutamine were significantly less in hydrocortisone-treated infants compared with control infants. In addition, the median duration of vasopressor treatment was halved in hydrocortisone-treated patients. Two versus 11 infants in the hydrocortisone and control groups required a second vasopressor for treatment of refractory hypotension. The trend (linear and quadratic) of the mean arterial blood pressure was also significantly and consistently higher in hydrocortisone-treated infants.
                A stress dose of hydrocortisone was effective in treating refractory hypotension in VLBW infants. Although routine and prophylactic use of systemic corticosteroids could not be recommended because of their potential adverse effects, this relatively low dose of hydrocortisone would probably be preferable to high-dose dexamethasone for treatment of refractory hypotension in emergency and life-threatening situations. To compare the efficacy of hydrocortisone with dopamine for the treatment of hypotensive, very low birthweight (VLBW) infants.
                Forty infants were randomly allocated to receive either hydrocortisone (n = 21) or dopamine (n = 19).
                All 19 infants randomised to dopamine responded; 17 of 21 (81%) did so in the hydrocortisone group. Three of the four non-responders in the hydrocortisone group had clinically significant left to right ductal shunting. The incidence of bronchopulmonary dysplasia, retinopathy of prematurity, intraventricular haemorrhage, necrotising enterocolitis, symptomatic patent ductus arteriosus, hyperglycaemia, sepsis (bacterial or fungal) or survival did not differ between groups. The adrenocorticotrophic hormone (ACTH) stimulated plasma cortisol activity, either before or after treatment, did not differ between the two groups of infants. Although a significant difference in efficacy between dopamine and hydrocortisone was not noted (P = 0.108), there were four treatment failures in the hydrocortisone group, compared with none in the dopamine group.
                Both hydrocortisone and dopamine are effective treatments for hypotension in very low birthweight infants. Extremely low birth weight (ELBW) infants are at risk for hypotension. Abnormal adrenal function may play a role in the pathogenesis of hypotension, and therefore, the administration of hydrocortisone (HC) may be an effective treatment for hypotension in some infants. However, the efficacy of prophylactic HC to prevent the use of vasopressors for a defined hypotensive state has not been studied. We conducted a randomized-controlled trial to determine the potential role on adrenal insufficiency in early neonatal hypotension and to determine the effectiveness of prophylactic HC in reducing treatment of hypotension in ELBW infants.
                Infants were assigned to receive either HC or placebo within the first 3 hours of life. Therapy was continued for 5 days. The presence of hypotension was based on an operational definition and treatment with vasopressors (VP) was standardized based on an a priori protocol.
                A total of 34 patients were enrolled. Baseline characteristics were similar between groups. Of the HC group 25% received VP at 24 hours of age compared to 44% of the placebo group. On day of life 2, only 7% of the HC group received VP compared to 39% of the placebo group (p<0.05).
                Prophylactic treatment with HC reduces the incidence of hypotension, defined by treatment with VP, among ELBW infants during the first 2 days of life. However, the mounting evidence that prophylactic administration of glucocorticoids in the first days of life is harmful to ELBW infants makes HC prophylaxis unwise until the efficacy of treatment relative to safety can be clearly established. 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. 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 the efficacy of dopamine and dobutamine for the treatment of hypotension (mean arterial blood pressure, < or = 30 mm Hg) in preterm (< or = 34 weeks of gestation) infants with respiratory distress syndrome in the first 24 hours of life, we enrolled 63 hypotensive preterm infants in a randomized, blind trial. Inclusion criteria required an arterial catheter for measurement of mean arterial blood pressure, treatment with exogenous surfactant, and persistent hypotension after volume expansion with 20 ml/kg (packed erythrocytes if hematocrit < 0.40, 5% albumin if > or = 0.40). Intravenous study drug infusions were initiated at 5 micrograms/kg per minute and then increased in increments of 5 micrograms/kg per minute at 20-minute intervals until a mean arterial blood pressure > 30 mm Hg was attained and sustained for > or = 30 minutes (success) or a maximum rate of 20 micrograms/kg per minute was reached without resolution of hypotension (failure). The study groups at entry were comparable for birth weight, gestational age, postnatal age, gender, birth depression, hematocrit < 0.40, heart rate, oxygenation index, delivery route, maternal chorioamnionitis, and maternal magnesium or ritodrine therapy. No infants in the dopamine group had a treatment failure (0/31; 0%); (16%) of 32 infants failed to respond to dobutamine (p = 0.028). Success was attained at < or = 10 micrograms/kg per minute in 30 (97%) of 31 infants given dopamine and in 22 (69%) of 32 infants given dobutamine (p < 0.01). Among those treated successfully, the increase in mean arterial blood pressure was significantly higher in those given dopamine (mean, 11.3 vs 6.8 mm Hg; p = 0.003). We conclude that dopamine is more effective than dobutamine for the early treatment of hypotension in preterm infants with respiratory distress syndrome. 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. Patients treated long-term with supraphysiologic doses of glucocorticoids experience secondary adrenal insufficiency and are routinely given large doses of steroids in the perioperative period to prevent hypotension. Because the dose of steroids required to prevent hypotension is not known, we conducted a randomized, double-blind study to determine whether patients treated long-term with glucocorticoids actually require increased steroids in the perioperative period.
                Patients who had been taking at least 7.5 mg prednisone daily for several months and had secondary adrenal insufficiency as defined by adrenocorticotropic hormone testing formed the study population. Patients were randomized to two groups. One group received perioperative injections of saline solution alone; the other received perioperative saline solution and cortisol. All patients received their usual daily prednisone dose throughout the study.
                Six patients were in the steroid-treated group and 12 were in the saline-treated group. Most subjects underwent major operations such as joint replacements, abdominal operations, and miscellaneous other procedures. Two patients had hypotension, one in each group. Hypotension resolved with volume replacement in both patients. The average pulse rates and blood pressures were similar in both groups during the perioperative period.
                Patients with secondary adrenal insufficiency do not experience hypotension or tachycardia caused by inadequate glucocorticoid levels when given only their daily dose of steroids for surgical procedures. To investigate the effect of hydrocortisone treatment on survival without bronchopulmonary dysplasia (BPD) and to study whether serum cortisol concentrations predict the response.
                We performed a randomized, placebo-controlled trial on infants with gestation < or =30 weeks, body weight of 501 to 1250 g, and respiratory failure. Hydrocortisone was started before 36 hours of age and given for 10 days at doses from 2.0 to 0.75 mg/kg per day. Shortly before hydrocortisone treatment, basal and stimulated (ACTH, 0.1 microg/kg) serum cortisols were measured.
                The study was discontinued early, because of gastrointestinal perforations in the hydrocortisone group (4/25 vs 0/26, P = .05); 3 of the 4 had received indomethacin/ibuprofen. The incidence of BPD (28% vs placebo 42%, P = 0.28) tended to be lower, and patent ductus arteriosus (36% vs 73%, P = .01) was lower in the hydrocortisone group. The hydrocortisone-treated infants with serum cortisol concentrations above the median had a high risk of gastrointestinal perforation. In infants with cortisol values below the median, hydrocortisone treatment increased survival without BPD.
                Serum cortisol concentrations measured shortly after birth may identify those very high-risk infants who may benefit from hydrocortisone supplementation.
Hydrocortisone may be as effective as dopamine when used as a primary treatment for hypotension. But the long term safety data on the use of hydrocortisone in this manner is unknown.Steroids are effective in treatment of refractory hypotension in preterm infants without an increase in short term adverse consequences. However, long term safety or benefit data is lacking. With long term benefit or safety data lacking steroids cannot be recommended routinely for the treatment of hypotension in preterm infants.
