Advair: combination treatment with fluticasone propionate/salmeterol in the treatment of asthma.
Nelson HS.
National Jewish Medical and Research Center, Denver, Colo 80206, USA.
Several classes of medications are available for the treatment of asthma, and often they must be taken concurrently
to achieve asthma control. Based on the understanding of asthma as an inflammatory disease, the National Heart Lung and Blood
Institute guidelines provide a stepwise approach to pharmacologic therapy. Corticosteroid therapy, principally inhaled corticosteroid
(ICS) therapy, is considered the most effective anti-inflammatory treatment. In cases of moderate-to-severe persistent asthma,
the addition of a second long-term control medication to ICS therapy is one recommended treatment option. A combination-product
inhaler (Advair, Seretide) was developed to treat both the inflammatory and bronchoconstrictive components of asthma by delivering
a dose of the ICS, fluticasone propionate, and a dose of the long-acting beta2-adrenergic (LABA) bronchodilator, salmeterol.
The Advair Diskus is available in 3 strengths of fluticasone propionate (100, 250, and 500 microg) and a fixed dose (50 microg)
of salmeterol. Combination treatment with both ICS and LABA provides greater asthma control than increasing the ICS dose alone,
while at the same time reducing the frequency and perhaps the severity of exacerbations. Furthermore, salmeterol added to
ICS therapy provides superior asthma control compared with the addition of leukotriene modifiers or theophylline. The superior
control is likely a consequence of the complementary actions of the drugs when taken together, including the activation of
the glucocorticoid receptor by salmeterol. By combining anti-inflammatory treatment with a long-acting beta2-agonist in a
single inhaler (1 inhalation twice daily), physicians can provide coverage for both the inflammatory and bronchoconstrictive
aspects of asthma without introducing any new or unexpected adverse consequences. The most common drug-related adverse events
were those known to be attributable to the constituent medications (ICS therapy and/or LABA therapy). Although the benefits
of combined ICS plus LABA therapy can be achieved with separate inhalers, the convenience of the combination product may improve
patient adherence and may therefore reduce the morbidity of asthma.

OBJECTIVE: The aim of this study was to investigate the effects of long-term inhaled corticosteroids on bone mineral
density (BMD) of the mandible in relation with the tooth loss. DESIGN: Cross sectional analytic study. SUBJECTS AND METHODS:
Patients (n = 30) with chronic obstructive pulmonary disease under inhaled corticosteroid therapy for at least 1 year were
compared with sex- and age-matched healthy controls (n = 30). BMD of the mandible was measured by dual-energy X-ray absorptiometry.
The clinical examination included recording the number of teeth present together with periodontal condition. Levels of serum
osteocalcin, alkaline phosphatase, calcium, phosphorus and cortisol were also assessed. RESULTS: BMD of the mandible in patients
on corticosteroid treatment was significantly lower than that in the control group (P = 0.001). Patients under treatment had
more missing teeth than the control group but the difference did not reach statistical significance. The two groups exhibited
similar clinical parameters of periodontal condition. Significantly lower levels of osteocalcin (P < 0.0001), calcium (P
= 0.004) and cortisol (P = 0.03) were observed in the patients on corticosteroid treatment. CONCLUSION: Long-term use of inhaled
corticosteroids may impair bone metabolism and lead to a marked decrease in the mandibular BMD.

Impact of long-term inhaled corticosteroid therapy on bone mineral density: results of a meta-analysis.
Halpern MT, Schmier JK, Van Kerkhove MD, Watkins M, Kalberg CJ.
Exponent, Alexandria, Virginia, USA. mhalpern@exponent.com
BACKGROUND: The impact of long-term inhaled corticosteroid (ICS) therapy on bone mineral density (BMD) is poorly understood.
OBJECTIVE: To evaluate the impact of long-term ICS use on BMD. METHODS: Random-effects meta-analysis. Published and unpublished
literature were identified by searches of MEDLINE and EMBASE databases and consultation with experts. Studies reporting BMD
among adult asthma and chronic obstructive pulmonary disease (COPD) patients using ICS and non-ICS controls were identified.
Studies selected for review included at least 1 year of follow-up. Two independent reviewers evaluated studies; data from
those meeting specified inclusion criteria were abstracted for inclusion in the meta-analysis. RESULTS: Fourteen (5.3%) of
266 reviewed studies met specified inclusion criteria. Sufficient data were available to perform meta-analysis on 3 measures
for ICS-using patients (lumbar, femoral neck, and major trochanter BMD) and 1 measure (lumbar BMD) for non-ICS-using controls.
Using current National Asthma Education and Prevention Program definitions, the majority of studies (12 of 14) included patients
receiving moderate to high doses of ICSs. Among ICS users, annual changes from baseline in lumbar, femoral neck, and major
trochanter BMD (-0.23%, -0.17%, and +1.46%, respectively) were not statistically significant. Mean changes in lumbar BMD were
also not significantly different from controls (-0.02%). Further, annual changes in lumbar BMD were not statistically significant
for subgroups of patients with asthma or COPD. CONCLUSIONS: Long-term use of ICSs in patients with asthma or COPD was not
associated with significant changes in BMD.

Adding salmeterol to an inhaled corticosteroid: long-term effects on bronchial inflammation in asthma.
Koopmans JG, Lutter R, Jansen HM, van der Zee JS.
Academic Medical Centre / University of Amsterdam, Netherlands.
Background: Adding the long-acting beta(2)-agonist salmeterol to inhaled corticosteroids leads to better symptomatic
asthma control than increasing the dose of inhaled corticosteroids. However, little is known about the long-term effects of
adding salmeterol on the asthmatic inflammatory process, control of which is considered important for the long-term outcome
of asthma. Methods: After a 4-week fluticasone run-in period, we randomized 54 allergic asthmatics to receive 1 year of twice
daily treatment with fluticasone 250 microg with or without salmeterol 50 microg, in a double-blind, parallel group design
(total daily dose of fluticasone 500 microg in both treatment groups). Primary outcomes were sputum eosinophil numbers and
eosinophil cationic protein concentrations. Secondary outcomes were neutrophil-associated sputum parameters and a respiratory-membrane
permeability marker. Effects on allergen-induced changes were determined before and at the end of the randomized treatment
period. Results: Adding salmeterol to fluticasone resulted in improved peak expiratory flows, symptom scores, rescue- medication-usage
and bronchial hyperresponsiveness (p-values <0.05). We found no sustained effect on sputum cell differentials and cytokine
concentrations, neither throughout the treatment period nor on changes induced by the end-of-treatment allergen challenge
(p-values >0.05). However, adding salmeterol significantly reduced sputum ratios of alpha(2)-macroglobulin and albumin
throughout the randomized treatment period (p=0.001). Conclusions: This study shows no sustained effect on (allergen-induced)
cellular bronchial inflammation, but a significant improvement in size selectivity of plasma protein permeation across the
respiratory membrane by adding salmeterol to fluticasone. Possibly, this phenomenon contributes to the improved clinical outcomes
that result from adding a long-acting beta(2)-agonist to inhaled corticosteroids.

The effects of butterbur on the histamine and allergen cutaneous response.
Jackson CM, Lee DK, Lipworth BJ.
Tayside Centre for General Practice, University of Dundee, Dundee, Scotland.
BACKGROUND: Butterbur or Petasites hybridus is an herbal remedy that exhibits antihistamine and antileukotriene activity
and has been shown to attenuate the response to adenosine monophosphate challenge in patients with allergic rhinitis and asthma.
However, no data are available regarding its effects on the histamine and allergen cutaneous response. OBJECTIVE: To evaluate
the effects of butterbur compared with fexofenadine and montelukast on the histamine and allergen wheal and flare cutaneous
responses. METHODS: Atopic patients were randomized into a double-blind, double-dummy, crossover study to receive for 1 week
butterbur, 50 mg twice daily (8 AM and 10 PM); fexofenadine, 180 mg once daily (10 PM), and placebo once daily (8 AM); montelukast,
10 mg once daily (10 PM), and placebo once daily (8 AM); or placebo twice daily (8 AM and 10 PM). Patients attended the department
at 10 AM and had measurements of the cutaneous wheal and flare responses to histamine, allergen, and saline control at 10-minute
intervals for 60 minutes. RESULTS: Twenty patients completed the study. The mean +/- SE histamine wheal and flare responses,
respectively, were significantly attenuated (P < .05) by fexofenadine (9.4 +/- 1.8 mm2 and 13.5 +/- 3.2 mm2) compared with
placebo (15.5 +/- 3.3 mm2 and 179.8 +/- 74.3 mm2) but not by butterbur (16.4 +/- 2.1 mm2 and 297.7 +/- 121.2 mm2) or montelukast
(19 +/- 1.9 mm2 and 240.2 +/- 66.6 mm2). The allergen wheal and flare responses, respectively, were also significantly attenuated
(P < .05) by fexofenadine (31.1 +/- 6.3 mm2 and 256.9 +/- 86.5 mm2) compared with placebo (65.4 +/- 15.2 mm2 and 1,014.5
+/- 250.0 mm2) but not by butterbur (50.4 +/- 9.2 mm2 and 1,110.3 +/- 256.1 mm2) or montelukast (58.8 +/- 9.1 mm2 and 1,463.6
+/- 295.6 mm2). CONCLUSIONS: Butterbur did not produce any significant effects on the histamine and allergen cutaneous response
compared with placebo, whereas mediator antagonism with fexofenadine but not montelukast produced significant attenuation.
This finding would suggest that butterbur may not be effective in allergic skin disease.

BACKGROUND: Many people suffer from hay fever symptoms. Hypnosis has proved to be a useful adjunct in the treatment
of conditions where allergic phenomena have an important role. METHODS: Randomised parallel group study over an observation
period of two consecutive pollen seasons. Outcome data include nasal flow under hypnosis, pollinosis symptoms from diaries
and retrospective assessments, restrictions in well-being and use of anti-allergic medication. We investigated 79 patients
with a mean age of 34 years (range 19-54 years; 41 males), with moderate to severe allergic rhinitis to grass or birch pollen
of at least 2 years duration and mild allergic asthma. The intervention consisted of teaching self-hypnosis during a mean
of 2.4 sessions (SD 1.7; range 2-5 sessions) and continuation of standard anti-allergic pharmacological treatment. RESULTS:
Of 79 randomised patients, 66 completed one, and 52 completed two seasons. Retrospective VAS scores yielded significant improvements
in year 1 in patients who had learned self-hypnosis: pollinosis symptoms -29.2 (VAS score, range 0-100; SD 25.4; p < 0.001),
restriction of well-being -26.2 (VAS score, range 0-100; SD 28.7; p < 0.001. In year 2, the control group improved significantly
having learned self-hypnosis as well: pollinosis symptoms -24.8 (SD 29.1; p < 0.001), restriction of well-being -23.7 (SD
30.0; p < 0.001). Daily self-reports of subjects who learnt self-hypnosis do not show a significant improvement. The hazard
ratio of reaching a critical flow of 70% in nasal provocation tests was 0.333 (95% CI 0.157-0.741) after having learnt and
applied self-hypnosis.

Asthma is a common chronic condition that has long plagued the pediatric patient population. Asthma in children can
cause excessive school absenteeism, hospitalizations, and even death. Osteopathic manipulative treatment (OMT) is an underutilized
noninvasive treatment method for patients with asthma. The use of OMT may help decrease mortality and morbidity rates among
this patient group. The authors conducted a randomized controlled trial attempting to demonstrate the therapeutic relevance
of OMT in the pediatric asthma population. With a confidence level of 95%, results for the OMT group showed a statistically
significant improvement of 7 L per minute to 9 L per minute for peak expiratory flow rates. These results suggest that OMT
has a therapeutic effect among this patient population. The authors suggest that more clinical trials are required to better
demonstrate the effectiveness of OMT in patients with asthma.

Prophylactic and acute treatment with the homeopathic medicine, Betula 30c for birch pollen allergy: a double-blind,
randomized, placebo-controlled study of consistency of VAS responses.

A study of the consistency of responses by allergic patients in repeated studies of the homeopathic remedy Betula
30c or placebo against birch pollen allergy, was made. A randomized, double-blind, placebo-controlled trial was performed
including participants with a known allergy to birch pollen. Allergy symptoms were assessed on a visual analogue scale (VAS)
by patients or parents each day during a 20-day period during two different pollen seasons. The work was carried out in Oslo,
Norway during May 1995, 1996 and 1997. There were 51 patients ranging in age from 7 to 50y. The homeopathic remedy Betula
30c or placebo was given as tablets, both as a prophylactic agent, once a week for 4 weeks before the pollen season started,
and as an acute remedy during the pollen season. The mean value of the symptom scores on the visual analogue scale, for all
registration days from each patient was the main outcome. The patient groups that received either placebo or Betula 30c for
two successive years showed a consistent response (r=0.75, P=0.01 and r=0.70, P=0.003, respectively). No such correlation
was found in the two groups that changed remedy from one year to another (either from placebo to Betula or vice versa). Subjective
assessment of allergic symptoms to birch pollen differed more from one year to another when different regimens (placebo or
homeopathic) had been administered these two seasons, than when the same treatment had been given.
