Inhaled steroids are increasingly advocated as first line treatment for mild asthma. Some studies suggest that inhaled steroids suppress bone formation as reflected by a fall in plasma osteocalcin. Spacers have been shown to increase the proportion of inhaled aerosol that is deposited in the lungs and to reduce the amount swallowed. We measured plasma osteocalcin levels to determine the effect on bone formation of inhaled beclomethasone dipropionate (BDP) with and without a 750 ml spacer in a double-blind, randomised, placebo-controlled, cross-over study. Twenty-six healthy male volunteers took BDP 500 micrograms (two puffs of Becloforte) together with two puffs of placebo, inhaled twice daily for seven days. One inhaler was taken directly while the other was inhaled through a 750 ml spacer. After a two week washout period, the inhalers were exchanged so that BDP was taken by the alternate route for a further seven days. Fasting plasma osteocalcin levels were measured at 09.00 h before and at the end of each week. After a week of BDP taken directly (without a spacer), osteocalcin levels fell from 11.8 (SEM 0.6) ng/ml to 9.5 (SEM 0.5) ng/ml (p < 0.001). After a week of BDP taken through a spacer, osteocalcin levels fell from 12.1 (SEM 0.5) ng/ml to 11.1 (SEM 0.5) ng/ml (p < 0.001). The fall in osteocalcin when a spacer was used was significantly less than when BDP was taken directly (p < 0.005). This is likely to be because the systemic effects on bone are caused by swallowed rather than inhaled BDP, and this is limited by the use of a spacer. Spacers should be more widely prescribed with inhaled steroids. Further prospective studies are indicated to evaluate whether spacers protect bone mass. 相似文献

106 chronic obstructive pulmonary disease (COPD) cases were divided into two groups, 53 cases treated with Shou Er Kang (SEK) pill (Kidney-reinforcing regimen) and high dose beclomethasone dipropionate inhaler, and 53 cases in the control group with high dose beclomethasone dipropionate aerosol alone. 64 patients were suffering from bronchial asthma and 42 patients from asthmatic bronchitis, sufficiently severe to be treated with inhaled corticosteroids. The results showed that the total effective rate was 100% and 96.9% in asthmatic patients of both groups; the total effective rates for asthmatic bronchitis patients were 85.7% in the SEK group and 52.4% in the control group. The Synacthen test showed that after the treatment, the adrenal cortex reserve power and secretive ability of the SEK group not only was intact but also improved markedly under high dose exogenous steroids. The adrenocortical secretive ability and reserve power of the control group were damaged with the inhalation of the newer steroids. The difference between the two groups was very significant (P less than 0.001); the relapse rate in the SEK group was 26.9%, but 40% in the control group. The results suggested that there were some occult disorders in COPD patients, especially asthmatic bronchitis patients at different levels on hypothalamus-pituitary-adrenocortical axis. 相似文献

An open long-term trial of inhaled beclomethasone dipropionate was carried out in 32 asthmatic patients chronically dependent on systemic corticosteroids. Our objectives were to study the efficacy and safety of beclomethasone and to determine the proportion of patients in whom systemic steroids could be replaced by the new drug. All subjects had a clear history and physical findings of asthma as well as significant improvement in respiratory function after inhalation of salbutamol. Patients were followed for 4 to 8 years. Compared with a baseline period, patients receiving beclomethasone had reduced symptoms and needed less bronchodilator therapy, but their pulmonary function was unchanged. Bronchial biopsy specimens from seven patients who had been taking beclomethasone for as long as 8 years did not differ histologically from specimens from five asthmatic patients who had never taken the drug. Nine patients were able to stop taking systemic corticosteroids within 9 months, eight required them occasionally, and in eight the requirement was substantially reduced; the requirement did not change appreciably in the remaining seven. Inhaled beclomethasone is a safe and effective drug for chronic administration to asthmatic patients, and in 78% of our subjects the need for systemic steroids was substantially reduced or eliminated. 相似文献

The effect of inhaled beclomethasone dipropionate (dose, 400 μg daily) was investigated in 31 prednisone-dependent asthmatics. In a double-blind noncrossover study of 25 patients dependent on a daily prednisone dose of 17.5 mg or less, the dose of ingested prednisone was significantly diminished through the use of beclomethasone as compared with placebo (P < 0.001). In a subsequent single-blind study of the 12 patients who had received placebo, a similar decrease in prednisone dose was possible when these patients received beclomethasone. In all 25 patients the effect of beclomethasone was maintained for 2 years; 9 came to require less beclomethasone and 1 required more. In an additional single-blind study of six patients with severe asthma, dependent on prednisone in a dose of 20 to 25 mg/d, the response to beclomethasone was more variable and less significant (P < 0.01). However, at 2 years there was no significant benefit (P > 0.05) and there were two treatment failures.
In patients in whom reduction of dose or discontinuation of prednisone was possible plasma cortisol values before and after corticotropin administration increased significantly (P < 0.001). Prednisone reduction was associated with the appearance of mild musculoskeletal steroid-withdrawal symptoms of short duration in 15 patients, and recurrence of symptoms of rhinitis in 15 patients. Side effects of beclomethasone included episodes of hoarseness in 6 and easily treated oropharyngeal Candida albicans infection in 14.

Preventive treatment: * Inhaled corticosteroids are indicated in children with asthma who have more than mild persistent asthma or are unresponsive to non-steroidal medications after 2-4 weeks. * Initial administration of 400 microg/day of chlorofluorocarbon-beclomethasone dipropionate, or budesonide, or 200 microg/day of fluticasone propionate or hydrofluoroalkane-beclomethasone dipropionate, is suggested, with subsequent titration of the dose to achieve ongoing control with the lowest dose possible. * In situations where asthma control cannot be achieved with the above doses of inhaled corticosteroids, the addition of a long-acting beta2-agonist, theophylline or a leukotriene antagonist should be considered. * Specialist referral is recommended in children requiring high doses of inhaled steroids, regular oral steroids or in whom there is concern about possible steroid side effects. Treatment of acute asthma: * Systemic corticosteroid therapy is recommended for children with moderate to severe acute asthma or if there is incomplete response to beta2-agonists. * Initial administration of 1 mg/kg prednisolone (maximum, 50 mg) orally is suggested, and this may be repeated every 12-24 hours, depending on response. While a course of up to three days is generally sufficient, in more severe cases a prolonged course (with tapering) may occasionally be indicated. * The need for recurrent systemic corticosteroid therapy for acute episodes is an indication for reassessment of the child's interval therapy. 相似文献

Clinical observations have shown that some older patients are unable to learn to use a metered dose inhaler (MDI) despite having a normal abbreviated mental test (AMT) score, possibly because of dyspraxia or unrecognised cognitive impairment. Thirty inhaler-naive inpatients (age 76–94) with an AMT score of 8–10 (normal) were studied. Standard MDI training was given and the level of competence reached was scored (inhalation score). A separate observer performed the minimental test (MMT), Barthel index, geriatric depression score (GDS), ideational dyspraxia test (IDT), and ideomotor dyspraxia test (IMD). No correlative or threshold relationship was found between inhalation score and Barthel index, GDS, or IDT. However, a significant correlation was found between inhalation score and IMD (r = 0.45, p = 0.039) and MMT (r = 0.48, p = 0.032) and threshold effects emerged in that no subject with a MMT score of less than 23/30 had an inhalation score of 5/10 or more (adequate technique requires 6/10 or more), and all 17/18 with an inhalation score of 6/10 or more had an IMD of 14/20 or more. The three patients with a MMT >22 and inhalation score <6 had abnormal IMD scores. Inability to learn an adequate inhaler technique in subjects with a normal AMT score appears to be due to unrecognised cognitive impairment or dyspraxia. The MMT is probably a more useful screening test than the AMT score in this context. 相似文献

OBJECTIVE--To examine the relationship between patterns of use of inhaled beclomethasone dipropionate and the risk of fatal and near-fatal asthma. DESIGN--Nested case-control analysis of a historical cohort; a further analysis. SETTING--The 12,301 residents of Saskatchewan aged 5 to 54 years who were dispensed 10 or more asthma drugs from 1978 to 1987. PATIENTS--The 129 persons who experienced asthma death (n = 44) and near-death (n = 85) and their 655 controls matched as to age and date of entry into the cohort, with the additional matching criteria of at least one hospitalization for asthma in the prior 2 years, region of residence, and having received social assistance. MAIN OUTCOME--Life-threatening attacks of asthma defined as death due to asthma or the occurrence of hypercarbia, intubation, and mechanical ventilation during an acute attack of asthma. RESULTS--After accounting for the risk associated with use of other medications and adjustment for markers of risk of adverse events related to asthma, subjects who had been dispensed, on average, one or more metered-dose inhalers of beclomethasone per month over a 1-year period had a significantly lower risk of fatal and near-fatal asthma (odds ratio, 0.1; 95% confidence interval, 0.02 to 0.6). CONCLUSION--These data support recent guidelines from several countries that recommend the use of inhaled corticosteroids in moderate and severe asthma. 相似文献

A double-blind crossover placebo controlled study was performed on 20 patients with stable chronic asthma, in order to obtain dose response data to ipratropium bromide (40, 80, 200 micrograms) given by metered dose inhaler. The use of the 200 micrograms dose gave a significantly greater peak effect and duration of action than the recommended standard therapeutic dose of 40 micrograms. There were marked individual variations in response to higher doses. Maximum response detected by spirometry occurred within 24 hours of inhalation, thus patients likely to gain clinical benefit are readily identified. The higher dose was well tolerated by most patients and may have clinical application in the treatment of patients who do not respond to the standard dose regime. 相似文献
