Suppression of adrenal function in children with acute lymphoblastic leukemia following induction therapy with corticosteroid and other cytotoxic agents.
Although treatment with corticosteroids induces remission in Crohn's disease, prolonged exposure to corticosteroids is undesirable. This randomised clinical trial evaluated the efficacy of recombinant human granulocyte-macrophage colony-stimulating factor (sargramostim), an activator of innate immunity, in corticosteroid-dependent patients with Crohn's disease.
                Patients were randomised in a 2:1 ratio, to sargramostim 6 microg/kg subcutaneously once daily or placebo for up to 22 weeks. The study consisted of (1) an adjunctive phase (weeks 1-4) in which patients received study drug plus corticosteroid therapy; (2) a forced corticosteroid tapering phase (weeks 4-14); and (3) an observation phase (4 weeks) in which patients received study drug plus prednisone < or =7.5 mg. The primary endpoint was corticosteroid-free remission (Crohn's Disease Activity Index (CDAI) < or =150) 4 weeks after corticosteroid elimination. Secondary endpoints were corticosteroid-free response (CDAI decreased by > or =100) and induction of remission in patients who reduced the dose of corticosteroid to 2.5-7.5 mg.
                Eighty-seven patients were randomised to sargramostim and 42 to placebo. Significantly more sargramostim-treated patients than placebo patients achieved corticosteroid-free remission (18.6% vs 4.9%; p = 0.03). Similar differences were seen for corticosteroid-free response and in patients who tapered corticosteroids to 2.5-7.5 mg/day. Sargramostim treatment was also associated with significant improvements in health-related quality of life. Patients who received sargramostim were more likely to experience musculoskeletal pain, injection site reactions and dyspnoea.
                Sargramostim was more effective than placebo for inducing corticosteroid-free remission in patients with Crohn's disease with corticosteroid dependence. Sargramostim may provide significant benefit in this population if these findings are confirmed. To investigate how frequently adrenal function fails to recover after corticosteroid therapy in children with acute lymphoblastic leukemia and to explore the clinical impact of slow adrenal recovery without steroid substitution.
                Low-dose (1 microg) adrenocorticotropic hormone tests were performed before and after steroid courses and during infectious episodes in 24 children. Test results were not available during the study.
                All 13 patients tested before treatment had normal adrenal responses. Adrenal suppression was found in 8 (47%) of 17 patients 5 days after discontinuation of a 5-week induction course of prednisolone and in 1 (20%) of 5 patients 7 days after a 3-week intensification course of dexamethasone, both courses being tapered over 9 days, as well as in all 13 patients tested 2 days after a 1-week prednisolone course. Clinically significant manifestations of adrenal suppression were noted in 3 (12%) patients. Of 204 scheduled tests, 131 were performed.
                High-dose glucocorticoid therapy may cause adrenal suppression lasting more than 1 week in children with acute lymphoblastic leukemia, even after tapering the dose. We suggest steroid replacement during stress episodes within 1 to 2 weeks after discontinuation and thereafter testing adrenal function selectively in accordance with symptoms. Recent studies suggested that administration of corticosteroids may improve clinical outcomes in patients with severe pneumonia.
                The aim of this study was to assess the effectiveness of corticosteroids as an adjunctive therapy in community-acquired pneumonia (CAP) requiring hospitalization.
                An open label, prospective, randomized control study was conducted from September 2003 to February 2004 in a community general hospital in Japan.
                Thirty-one adult CAP patients who required hospitalization were enrolled.
                Fifteen patients received 40 mg of prednisolone intravenously for 3 days (steroid group). Sixteen patients did not receive prednisolone (control group). Both groups were also evaluated for their adrenal function. The primary endpoint was length of hospital stay. Secondary endpoints were duration of intravenous (IV) antibiotics and time required to stabilize vital signs. Both groups demonstrated similar baseline characteristics and length of hospital stay, and yet a shorter duration of IV antibiotics was observed in the steroid group (p < 0.05). In addition, vital signs were stabilized earlier in the steroid group (p < 0.05). These differences were more prominent in the moderate-severe subgroup but not as significant in the mild-moderate subgroup. The prevalence of relative adrenal insufficiency (RAI) in both groups was high (43%), yet there was no difference in baseline characteristics between patients, with or without RAI. In multiple regression models, RAI seemed to have no influence on clinical courses.
                In moderate-severe CAP, administration of corticosteroids promotes resolution of clinical symptoms and reduces the duration of intravenous antibiotic therapy. Although their clinical efficacy is unclear and they may cause serious adverse effects, systemic glucocorticoids are a standard treatment for patients hospitalized with exacerbations of chronic obstructive pulmonary disease (COPD). We conducted a double-blind, randomized trial of systemic glucocorticoids (given for two or eight weeks) or placebo in addition to other therapies, for exacerbations of COPD. Most other care was standardized over the six-month period of follow-up. The primary end point was treatment failure, defined as death from any cause or the need for intubation and mechanical ventilation, readmission to the hospital for COPD, or intensification of drug therapy.
                Of 1840 potential study participants at 25 Veterans Affairs medical centers, 271 were eligible for participation and were enrolled; 80 received an eight-week course of glucocorticoid therapy, 80 received a two-week course, and 111 received placebo. About half the potential participants were ineligible because they had received systemic glucocorticoids in the previous 30 days. Rates of treatment failure were significantly higher in the placebo group than in the two glucocorticoid groups combined at 30 days (33 percent vs. 23 percent, P=0.04) and at 90 days (48 percent vs. 37 percent, P=0.04). Systemic glucocorticoids (in both groups combined) were associated with a shorter initial hospital stay (8.5 days, vs. 9.7 days for placebo, P=0.03) and with a forced expiratory volume in one second that was about 0.10 liter higher than that in the placebo group by the first day after enrollment. Significant treatment benefits were no longer evident at six months. The eight-week regimen of therapy was not superior to the two-week regimen. The patients who received glucocorticoid therapy were more likely to have hyperglycemia requiring therapy than those who received placebo (15 percent vs. 4 percent, P=0.002).
                Treatment with systemic glucocorticoids results in moderate improvement in clinical outcomes among patients hospitalized for exacerbations of COPD. The maximal benefit is obtained during the first two weeks of therapy. Hyperglycemia of sufficient severity to warrant treatment is the most frequent complication. To evaluate the efficacy and safety of the topical corticosteroid budesonide, given in an oral controlled release formulation for maintenance of remission in patients with ileal and ileocaecal Crohn's disease (CD).
                Out of 176 patients with active CD who had achieved remission (CD activity index score < or = 150) after 10 weeks' treatment with either budesonide or prednisolone, 90 were randomised to continue with once daily treatment of 6 mg budesonide, or 3 mg budesonide or placebo for up to 12 months in a double blind, multicentre trial. Time to symptomatic relapse was calculated using Kaplan-Meier estimates. Morning plasma cortisol was measured at clinic visits and a corticotropin stimulation test was performed after three months of treatment.
                Thirty two patients were allocated to the 6 mg budesonide group, 31 to the 3 mg group, and 27 to the placebo group. After three months, 19 per cent of the patients in the 6 mg group had relapsed, compared with 45 per cent in the 3 mg group and 44 per cent in the placebo group (p = 0.047). The corresponding results after 12 months was 59 per cent in the 6 mg budesonide group, 74 per cent in the 3 mg group, and 63 per cent in the placebo group (p = 0.44). The median time to relapse or discontinuation was 258 days in the 6 mg group, 139 days in the 3 mg group, and 92 days in the placebo group (p = 0.021). Mean morning plasma cortisol values increased from entry in all three groups with no statistically significant differences at 12 months. All 13 patients remaining in the placebo group after three months had a normal corticotropin stimulation response, compared with 18 of 23 patients in the 6 mg, and 19 of 21 in the 3 mg budesonide groups (p = 0.14). Acne and moon face were slightly more common in the budesonide groups.
                6 mg budesonide once daily is significantly more efficacious than placebo in prolonging time to relapse in CD, and causes only minor systemic side effects. To determine the effectiveness of treatment with corticosteroids in patients with COPD.
                In this study, we investigated the effect of a 2-year treatment with corticosteroids on clinical symptoms and the decline of lung function in 58 nonallergic patients with COPD. Subjects were treated in a double-blind, randomized, placebo-controlled, parallel way with inhaled budesonide (bud), 1,600 micrograms/d; inhaled budesonide, 1,600 micrograms/d, plus oral prednisolone, 5 micrograms/d (bud + pred); or placebo (plac). Clinical assessment (history, physical examination, and spirometry) was carried out every 2 months. The rate of decline in FEV1 was assessed by calculating individual regression co-efficients from linear regression of FEV1 on time for each subject.
                Eleven patients dropped out. The number of withdrawals due to pulmonary problems was significantly higher in the plac group (n = 5 out of 18) than in the actively treated groups (n = 2 out of 40). Treatment with corticosteroids significantly reduced pulmonary symptoms. Median decline of FEV1 was 60 mL/yr in the plac group, 40 mL/yr in the bud + pred group, and 30 mL/yr in the bud group. Variation was large and differences were not statistically significant. No treatment effect was found on frequency or duration of exacerbations, possibly because of the high number of withdrawals due to pulmonary deterioration in the plac group. Treatment with a combination of inhaled plus oral corticosteroids was not more effective than inhaled corticosteroids alone. Morning plasma cortisol levels remained within the normal range in all three groups.
                Our study shows beneficial effects of long-term daily treatment with inhaled corticosteroids in patients with COPD with regard to symptoms and drop out due to pulmonary problems. Lung function decline tends to decrease during treatment with inhaled corticosteroids. The observed effects are limited but warrant further studies on the effectiveness of corticosteroids in larger numbers of patients with COPD. Lung inflammation and injury is critical in cystic fibrosis. An ideal antiinflammatory agent has not been identified but inhaled corticosteroids are widely used despite lack of evidence.
                To test the safety of withdrawal of inhaled corticosteroids with the hypothesis this would not be associated with an earlier onset of acute chest exacerbations.
                Multicenter randomized double-blind placebo-controlled trial in 18 pediatric and adult UK centers. Eligibility criteria included age>6.0 yr, FEV1>or=40% predicted, and corticosteroid use>3 mo. During the 2-mo run-in period, all patients received fluticasone; they then took either fluticasone or placebo for 6 mo.
                Fluticasone group: n=84, median age 14.6 yr, mean (SD) FEV1 76% (18); placebo group: n=87, median age 15.8 yr, mean (SD) FEV1 76% (18). There was no difference in time to first exacerbation (primary outcome) with hazard ratio (95% confidence interval) of 1.07 (0.68 to 1.70) for fluticasone versus placebo. There was no effect of age, atopy, corticosteroid dose, FEV1, or Pseudomonas aeruginosa status. There was no change in lung function or differences in antibiotic or rescue bronchodilator use. Fewer patients in the fluticasone group withdrew from the study due to lung-related adverse events (9 vs. 15%); with a relative risk (95% confidence interval) of 0.59 (0.23-1.48) fluticasone versus placebo.
                In this study population (applicable to 40% of patients with cystic fibrosis in the UK), it appears safe to consider stopping inhaled corticosteroids. Potential advantages will be to reduce the drug burden on patients, reduce adverse effects, and make financial savings. Relapses of acute asthma following emergency department (ED) discharge can be reduced with systemic corticosteroid treatment. However, whether inhaled corticosteroids (ICSs) provide additional benefit is not known. Objective To determine whether the addition of ICSs to oral corticosteroid treatment would reduce relapses in patients with acute asthma discharged from the ED.
                Placebo-controlled, double-blind, randomized clinical trial conducted in a community teaching hospital ED in Canada between November 1995 and September 1997, with a 21-day follow-up.
                A total of 1006 consecutive patients aged 16 to 60 years presented to the ED with acute asthma; after excluding those using oral and/or inhaled corticosteroids as well as those meeting other exclusion criteria, 188 were included in the study.
                Patients were discharged with a nontapering course of oral prednisone (50 mg/d) for 7 days. In a double-blind fashion, patients were randomly assigned to 1600 microg/d of inhaled budesonide (n = 94) or identical placebo (n = 94) for 21 days.
                Incidence of relapse, defined as an unscheduled visit for worsening asthma symptoms, in budesonide vs placebo groups. Secondary outcomes included response to the Asthma Quality of Life Questionnaire, beta2-agonist use, symptom score, global asthma improvement assessment, and pulmonary function.
                Five patients in the budesonide group and 3 in the placebo group either dropped out or were lost to follow-up but were included in primary analyses. After 21 days, 12 (12.8%) of 94 patients in the budesonide group experienced a relapse compared with 23 (24.5%) of 94 in the placebo group, a 48% relapse reduction (P=.049). Asthma Quality of Life Questionnaire scores were higher (better quality) in the budesonide group (P=.001), as well as for all domain scores (P=.001 to .01). Fewer beta2-agonist activations were used at the end of the trial by patients receiving budesonide (2.4/d vs 4.2/d; P=.01). Symptom scores (P=.001 to .004) and self-assessed asthma improvement scores (based on a 7-point Likert scale) (6.2 vs 5.2; P<.001) were higher (indicating fewer symptoms) for budesonide vs placebo. There were no differences in pulmonary function between the groups (peak expiratory flow rate: budesonide, 437 vs placebo, 453 L/min; P= .39) at 21 days. Using this approach, as few as 9 patients would require budesonide to prevent 1 relapse.
                Patients discharged from the ED following treatment for acute asthma benefit from added treatment with high-dose inhaled budesonide for 21 days compared with oral corticosteroids alone. To evaluate adrenal function in children with acute lymphoblastic leukemia (ALL) after induction therapy with corticosteroid and other cytotoxic agents. Study design Children with ALL (N=24) were treated with prednisolone (40 mg/m(2) per day) for 28 days during the induction phase followed by 1 week of oral dexamethasone every 4 weeks. A low-dose (1 microg) adrenocorticotropin (ACTH) test was performed 2 weeks after discontinuation of prednisolone; it was repeated 2 weeks later and then every 4 weeks in patients with adrenal suppression until normal response was achieved.
                Adrenal suppression was found in 46% of patients at 2 weeks after discontinuation of prednisolone; it persisted in 38%, 29%, and 13% of patients through 4 weeks, 8 weeks, and 20 weeks, respectively. Adrenal suppression appeared to last significantly longer in children aged >or=5 years than in children aged <5 years. Four children developed febrile neutropenia; all belonged to the adrenal suppressed group and were unable to mount an adequate adrenal response to the stress.
                About 50% of children with ALL developed adrenal suppression 2 weeks after a 4-week induction therapy with prednisolone. The suppression could persist through 20 weeks and may hinder an adequate adrenal response during acute febrile illness.
Corticosteroids are effective for induction of remission in patients with CD, particularly when used for more than 15 weeks. Although corticosteroids cause more adverse events than either placebo or low-dose 5-ASA, these adverse events did not lead to increased study withdrawal in the included studies. Further information is required to determine the optimal duration of treatment and tapering protocol to maximize the efficacy of treatment with corticosteroids. Additionally, further study is required to determine whether corticosteroids are more effective in patients with certain phenotypes or when administered intravenously.
