Immunotherapy vs inhaled budesonide in bronchial asthma: an open, parallel, comparative trial

BACKGROUND: Budesonide, an inhaled corticosteroid and specific immunotherapy, are both routinely used in the treatment of bronchial asthma. However, there are as yet, no studies comparing the effects of budesonide vs immunotherapy. OBJECTIVE: The aim of this study is to compare the effects of budesonide with immunotherapy in patients having perennial asthma. METHODS: This study is an open, parallel, comparative trial, in which 51 young patients were administered either immunotherapy or budesonide for 1 year and their global symptom scores and FEV1 values assessed. Both treatments were abruptly discontinued after 12 months and the effects of cessation analysed. RESULTS: The use of budesonide resulted in a faster and more striking improvement during the first few months as compared to immunotherapy, with an even more rapid decline in benefits on cessation of budesonide. Immunotherapy on the other hand, resulted in slow but steady improvement which did not decline as rapidly as budesonide on cessation. CONCLUSION: Although this was an open trial, it could be concluded that relief with inhaled corticosteroids in bronchial asthma is more rapid than immunotherapy; however the decline in benefit on cessation of inhaled corticosteroid is even more rapid, a phenomenon not seen with immunotherapy.     

Changes in bone markers in children with asthma during inhaled budesonide and nedocromil treatments

We evaluated serum and urinary markers of bone turnover in 14 children with asthma during inhaled budesonide and nedocromil treatments. Both the markers of formation (serum carboxy- and amino-terminal propeptides of type I procollagen and serum osteocalcin) and the markers of degradation (serum carboxy-terminal telopeptide of type I collagen and urinary pyridinium cross-links) decreased (p < 0.05) during budesonide treatment for 6 months. During inhaled nedocromil treatment (for the following 6 months), the markers returned to the normal levels. These transient decreases in the markers of both formation and degradation of bone suggest that inhaled budesonide may slightly decrease the bone turnover rate. However, normal "coupling" between formation and degradation seemed to operate, e.g. a change in one resulted in a corresponding change in the other, so that net bone loss did not necessarily occur.     

High-dose inhaled budesonide may substitute for oral therapy after an acute asthma attack

Patients attending the emergency room with acute asthma, participating in a study comparing salbutamol (albuterol in the United States) via a dry powder inhaler (Turbuhaler) with pressurized metered-dose inhaler (pMDI), were included in this 1-week follow-up study with the aim of assessing whether inhaled budesonide via Turbuhaler may be an alternative to prednisolone tablets after an acute asthma attack. Eighty-one patients with a mean age of 38 years and forced expiratory volume in 1 sec (FEV1) of 64% predicted normal value after treatment with salbutamol were randomized in this double-blind, double-dummy, parallel-group study. The doses given were budesonide 1600 microg b.i.d. or prednisolone in daily doses from 40 mg (day 1) decreased to 5 mg (day 7). FEV1 was recorded before and after the 7-day treatments and peak expiratory flow (PEF) morning and evening, clinical symptoms (visual analogue scale 0-100), and doses of rescue medication (terbutaline Turbuhaler 0.25 mg/dose) were recorded daily. The mean increase in FEV1 from baseline to day 7 was 17.3% in the budesonide Turbuhaler group and 17.6% in the prednisolone group. Mean values of morning PEF increased from day 1 to day 7 by 67 L/min in the budesonide Turbuhaler group and by 57 L/min in the prednisolone group (not significant). There were no statistically significant differences between the groups in clinical symptoms and in the number of doses of rescue medication. Because of disease deterioration, five patients in the Turbuhaler group and three in the prednisolone group needed additional symptomatic as well as corticosteroid treatment. Inhaled budesonide in high doses may be a substitute for oral therapy as follow-up treatment after an acute asthma attack.     

Posterior subcapsular cataracts, bruises and hoarseness in children with asthma receiving long-term treatment with inhaled budesonide

To study isoform-specific effects of apolipoprotein E (apoE) in vivo, we generated mice with a human APOE*2 allele in place of the mouse Apoe gene via targeted gene replacement in embryonic stem cells. Mice expressing human apoE2 (2/2) have virtually all the characteristics of type III hyperlipoproteinemia. Their plasma cholesterol and triglyceride levels are both twice to three times those in (normolipidemic) mice that are expressing human apoE3 (3/3) made in an identical manner. The 2/2 mice are markedly defective in clearing beta-migrating VLDL particles, and spontaneously develop atherosclerotic plaques, even on a regular diet. An atherogenic diet, high in fat and cholesterol, exacerbates development of atherosclerosis and xanthomas in the 2/2 mice. Thus, comparisons between the 2/2 and 3/3 mice unequivocally demonstrate that a single amino acid difference (Arg158 Cys) in the apoE protein is sufficient to cause type III HLP and spontaneous atherosclerosis in mice.     

The effect of the Russian inhalant glucocorticosteroid budesonide on bronchial inflammation and hyperreactivity during the long-term treatment of bronchial asthma patients

11 patients with severe bronchial asthma entered a randomized trial of glucocorticosteroid budesonide of Russian produce. Of them 6 patients received inhalations of budesonide (800 micrograms/day for 6 months), 5 control patients did not receive the drug. As shown by investigations of external respiration and bronchoalveolar lavage with estimation of cytogram, metacholine provocative tests, fiber bronchoscopy, budesonide inhalations relieved clinical symptoms of asthma, bronchial hyperreactivity and inflammation.     

Effect of inhaled formoterol and budesonide on exacerbations of asthma. Formoterol and Corticosteroids Establishing Therapy (FACET) International Study Group

BACKGROUND: The role of long-acting, inhaled beta2-agonists in treating asthma is uncertain. In a double-blind study, we evaluated the effects of adding inhaled formoterol to both lower and higher doses of the inhaled glucocorticoid budesonide. METHODS: After a four-week run-in period of treatment with budesonide (800 microg twice daily), 852 patients being treated with glucocorticoids were randomly assigned to one of four treatments given twice daily by means of a dry-powder inhaler (Turbuhaler): 100 microg of budesonide plus placebo, 100 microg of budesonide plus 12 microg of formoterol, 400 microg of budesonide plus placebo, or 400 microg of budesonide plus 12 microg of formoterol. Terbutaline was permitted as needed. Treatment continued for one year; we compared the frequency of exacerbations of asthma, symptoms, and lung function in the four groups. A severe exacerbation was defined by the need for oral glucocorticoids or a decrease in the peak flow to more than 30 percent below the base-line value on two consecutive days. RESULTS: The rates of severe and mild exacerbations were reduced by 26 percent and 40 percent, respectively, when formoterol was added to the lower dose of budesonide. The higher dose of budesonide alone reduced the rates of severe and mild exacerbations by 49 percent and 37 percent, respectively. Patients treated with formoterol and the higher dose of budesonide had the greatest reductions -- 63 percent and 62 percent, respectively. Symptoms of asthma and lung function improved with both formoterol and the higher dose of budesonide, but the improvements with formoterol were greater. CONCLUSIONS: In patients who have persistent symptoms of asthma despite treatment with inhaled glucocorticoids, the addition of formoterol to budesonide therapy or the use of a higher dose of budesonide may be beneficial. The addition of formoterol to budesonide therapy improves symptoms and lung function without lessening the control of asthma.     

Clinical efficacy of low-dose inhaled budesonide once or twice daily in children with mild asthma not previously treated with steroids

The aim of the present study was to examine the efficacy of low-dose inhaled budesonide (BUD) administered via Turbuhaler once or twice daily on symptoms, lung function and bronchial hyperreactivity in children with mild asthma. One hundred and sixty-three children (mean age 9.9 yrs, 56 females/107 males) with mild asthma (forced expiratory volume in one second (FEV1) 103% of predicted, morning peak expiratory flow (PEF) 87% pred, reversibility in FEV1 3%, fall in FEV1 after exercise 10.4% from pre-exercise value) and not previously treated with inhaled steroids, were included in a double-blind, randomized, parallel-group study. After a two-week run-in period, the children received inhaled BUD 100 microg or 200 microg once daily in the morning, 100 microg twice daily or placebo for 12 weeks. Exercise and methacholine challenges were performed before and at the end of treatment. After 12 weeks of therapy, the fall in FEV1 after an exercise test was significantly less in all three BUD groups (43-5.1%) than in the placebo group (8.6%). Bronchial hyperreactivity to methacholine with the provocative dose causing a 20% fall in FEV1 decreased significantly in the BUD 100 microg twice-daily group compared with placebo (ratio at the end of treatment 156%). Changes in baseline lung function (FEV1 and PEF) were less marked than changes in bronchial responsiveness. In conclusion, low doses of inhaled budesonide, given once or twice daily, provided protection against exercise-induced bronchoconstriction in children with mild asthma and near normal lung function.     

Oral glucocorticosteroid-sparing effect of budesonide administered by Turbuhaler: a double-blind, placebo-controlled study in adults with moderate-to-severe chronic asthma. Pulmicort Turbuhaler Study Group

The purpose of this study was to evaluate the correlation between alteration in telomere length and prognosis in patients with pathological stage I-II non-small cell lung cancer. We measured telomeric repeat length and telomerase activity by use of southern blot analysis of terminal restriction fragments and a non-radioactive ELISA-based assay, respectively. RESULTS: Alterations in TRF lengths were present in 17(29.8%) of 57 patients. Patients with altered TRF length had significantly shorter survival than did patients without (P = 0.0051). In multivariate analysis, only alteration in TRF length independently correlated with shortened survival (P = 0.0033).     

Beclomethasone dipropionate, budesonide and flunisolide in the treatment of bronchial asthma (a review of the literature and the authors' own research)

Inhalation corticosteroids (beclometasone dipropionate, budesonide, flunisolide) proved effective against bronchial asthma (BA) and safe as they induce no severe systemic side effects. Of these three drugs side effects arise most frequently in administration of beclometasone dipropionate, least frequently of flunisolide. These inhalation corticosteroids are indicated both in non-steroid-dependent and steroid-dependent BA to reduce the dose of oral steroids or, if possible, for their complete discontinuation. Flunisolide is the most potent and effective of all inhalation corticosteroids used in current practice.     

Erythema-multiforme-like contact dermatitis from budesonide

A three-fold greater incidence of chemical burn injuries in Jamaican hospitals, compared to burn centres in other industrial countries, underscores the problem of the use of common chemicals for assault weapons in this country. With the increased availability of guns for personal use, many Jamaicans learned the value of carrying household chemicals such as sulphuric acid from batteries or sodium hydroxide obtained from cleaning supplies. Chemicals carried in a container, such as one might carry mace, afforded a means of defence among the lower socioeconomic groups who could not afford handguns. This use of dangerous chemicals for defensive weapons has extended to the use of chemicals for assault. The pattern of chemical injury differs significantly from most reports in the literature in both prevalence and aetiology. This review was prepared to examine these injuries with a view to planning strategies for prevention.

Nebulized budesonide and oral dexamethasone for treatment of croup: a randomized controlled trial

CONTEXT: The effectiveness of glucocorticoids for patients with croup is well established but it remains uncertain which glucocorticoid regimen is most effective. OBJECTIVE: To determine the effectiveness of 3 glucocorticoid regimens in patients with croup. DESIGN: Randomized controlled trial with parallel design. SETTING: Emergency departments of 2 Canadian pediatric tertiary care hospitals. PARTICIPANTS: Children with a clinical syndrome consistent with croup, aged 3 months to 5 years, with a croup score of 2 or greater following at least 15 minutes of mist therapy. INTERVENTIONS: Oral dexamethasone, 0.6 mg/kg, and nebulized placebo; oral placebo and nebulized budesonide, 2 mg; or oral dexamethasone, 0.6 mg/kg, and nebulized budesonide, 2 mg. MAIN OUTCOME MEASURES: Westley croup score (primary outcome), hospital admission rates, time spent in the emergency department, return visits to the emergency department, or ongoing symptoms at 1 week. RESULTS: The mean change in the croup score from baseline to the final study assessment was -2.3 (95% confidence interval [CI], -2.6 to -2.0) in the budesonide group (n = 65), -2.4 (95% CI, -2.6 to -2.2) in the dexamethasone group (n = 69), and -2.4 (95% CI, -2.7 to -2.1) in the budesonide and dexamethasone group (n = 64, P = .70). CONCLUSIONS: Based on the similar outcomes in the 3 groups, oral dexamethasone is the preferred intervention because of its ease of administration, lower cost, and more widespread availability.     

Active sensitization to budesonide and para-phenylenediamine from patch testing

Fibrous dysplasia is a benign bone disorder. It is diagnosed by distinctive X-ray radiography, CT, and MRI findings. Although bone scintigraphy helps to identify the tumor origin according to accelerated bone turnover, the glucose metabolism in fibrous dysplasia has not yet been investigated. We reported a case of fibrous dysplasia in craniofacial bone which showed signs of the acceleration of bone mineral turnover without elevated glucose utilization by Technetium-99m-HMDP SPECT and Fluorine-18-FDG PET. We concluded that the growth of fibrous dysplasia needed the acceleration of bone mineral turnover without an increase in glucose metabolism.
