Abstract
BACKGROUND Monitoring noninvasive biomarkers of inflammation is an important adjunct in asthma therapy. OBJECTIVE The goal of the present study was to identify airway and alveolar site(s) of inflammation using exhaled nitric oxide (NO) as a marker in asthmatic patients, and to evaluate the NO response to maintenance fluticasone 250 microg/salmeterol 50 microg (F/S) and add-on montelukast 10 mg (M). METHODS Thirty (24 women) nonsmoking, mild to moderate asthmatic patients were studied, mean age (+/- SD) 43+/-9 years, treated with F/S for more than one year. All were clinically stable for longer than eight weeks and had not taken oral corticosteroids and/or leukotriene antagonists for eight weeks before the present study. Spirometry, Juniper asthma symptom score, fractional exhaled NO (FENO) 100 mL/s, bronchial NO and alveolar NO concentration (CANO) were measured in a single-blind, nonrandomized crossover study. PROTOCOL Visit 1: baseline F/S; visit 2: after four weeks of F/S plus M; visit 3: after four weeks of S plus M; and visit 4: after four weeks of S only. Values in asthmatic patients were also compared with 34 nonsmoking age-matched healthy controls with normal lung function. RESULTS After 180 microg aerosolized metered dose inhaler albuterol, the forced expiratory volume in 1 s at baseline was 2.6+/-0.8 L (86%+/-16% of the predicted value) and the forced expiratory volume in 1 s over the forced vital capacity was 77%+/-9% (mean +/- SD), and was similar at visits 2 to 4. Juniper scores were mildly abnormal at visits 1 to 3, but significantly worse (P=0.03) at visit 4 versus visits 1 to 3. FENO values at visits 1 to 3 were similar but significantly increased (P=0.007) at visit 4. Bronchial NO was higher (P=0.03) at visit 4, versus visits 1 and 2, and was no different at visit 3. Compared with the healthy subjects, FENO and bronchial NO values were abnormal (greater than the normal mean plus 2 SD) in 33% of asthmatic patients at visits 1 to 3. CANO was similar for visits 1 to 4. CANO was abnormal (greater than the normal mean + 2 SD) in 20% of asthmatic patients. CONCLUSION In clinically stable asthmatic patients, despite controller treatment including moderate-dose inhaled corticosteroids and add-on M, 33% of mild to moderate asthmatic patients have ongoing nonsuppressed bronchial sites of increased NO production, compared with healthy control subjects. These controllers have no effect on CANO, which was abnormal in 20% of the asthmatic patients studied. The addition of add-on M to baseline moderate-dose inhaled corticosteroid did not further reduce total exhaled, bronchial and/or alveolar NO production.

Abstract
Perennial allergic rhinitis (PAR) often causes sleep disturbances and associated daytime somnolence, thus resulting in a poor quality of life. Various clinical interventions in patients suffering from the disorder seek to improve symptoms and quality of life. Additional studies are needed to establish whether the alleviation of PAR symptoms, particularly the reduction of congestion, will improve sleep quality and reduce daytime somnolence. This study seeks to determine whether treatment with montelukast is more effective than placebo in reducing nasal congestion and sleep disturbances, resulting in reduced daytime somnolence and fatigue in patients with PAR. Thirty-one subjects were enrolled in a double-blinded, placebo-controlled study using Balaam's design. Patients were treated with montelukast or placebo. Collected subjective data included a daily diary recording nasal symptoms, sleep issues, and daytime fatigue, the Functional Outcomes of Sleep Questionnaire, the Epworth Sleepiness Scale, Juniper's Rhinoconjunctivitis Quality of Life Questionnaire, the Rhinitis Severity Scale, the Calgary Sleep Apnea Quality of Life Index, and Trail Making tests. Subjects treated with montelukast, compared with placebo, showed a statistically significant improvement in daytime somnolence (p = 0.0089) and daytime fatigue (p = 0.0087), with both factors improving with montelukast and worsening with placebo. In a small cohort of subjects, montelukast, when compared with placebo, improved the symptoms of PAR and reduced the fatigue and daytime somnolence associated with the disorder.

Abstract
BACKGROUND Aspirin-exacerbated respiratory disease can be diagnosed with oral aspirin challenges and treated with aspirin desensitization. OBJECTIVE To evaluate whether controller medications, particularly leukotriene modifier drugs, taken during oral aspirin challenges can reduce the risk of severe asthmatic responses. METHODS The medical records of 676 patients who had undergone oral aspirin challenges, followed by aspirin desensitization, were reviewed. Asthmatic responses were stratified based on severity of bronchospastic response or lack of response. The effect of pretreatment with controller medications on the outcome of oral aspirin challenges was measured. RESULTS Leukotriene modifier drugs had the most significant effect in protecting the lower airways from severe reactions (P = .004). The protective effect of leukotriene modifier drugs was observed in patients already taking systemic corticosteroids, where the addition of leukotriene modifier drugs significantly shifted the response toward a milder asthmatic response (P < .001). CONCLUSION Protection from significant aspirin-induced bronchospasm during oral aspirin challenge can be accomplished with leukotriene modifier drugs. The use of a combination of inhaled corticosteroids, long-acting beta-agonists, systemic corticosteroids, and leukotriene modifier drugs stabilized underlying airways in preparation for a reasonably safe and accurate oral aspirin challenge. However, only pretreatment with leukotriene modifier drugs enhanced the safety of oral aspirin challenge in patients with aspirin-exacerbated respiratory disease by significantly decreasing the degree of asthmatic responses. Therefore, outpatient oral aspirin challenges in most well-selected patients appear to be a reasonable decision.

Allergy and asthma proceedings. 2006;(4):383-6
Abstract
Proinflammatory cytokines such as tumor necrosis factor (TNF) alpha and soluble interleukin 2 receptor (sIL-2R) are very important mediators in induction of inflammatory response in lung. The aim of this study was to investigate anti-inflammatory response of cysteinyl leukotriene receptor antagonist montelukast on macrophage and T-cell activation by sIL-2R and TNF-alpha in mild atopic asthmatic children. Fifteen children with mild-to-moderate atopic asthma and 15 nonatopic children as control, enrolled in the study. Asthmatic children were treated with montelukast, 5-mg tablets, for 1 month. Lung function test forced expiratory volume in 1 second (FEV1) was performed before and after treatment. Serum TNF-alpha, sIL-2R, and eosinophil cationic protein levels were determined in the control group and in asthmatic children before and after treatment. The mean eosinophil cationic protein value was significantly decreased (33.1 +/- 14.8 and 22.2 +/- 12.1; p < 0.05) and FEV1 was significantly increased (86.9 +/- 20.9 and 102.1 +/- 12.7; p < 0.05) after 1 month treatment with montelukast. The mean serum IL-2R levels were significantly higher in the before treatment group than in the after treatment group (1061.9 +/- 491 and 794 +/- 230.9; p < 0.05) or in control subjects (581.1 +/- 123; p < 0.01). The mean serum TNF-alpha level was higher in the before treatment group than in the after treatment group and control group (7.30 +/- 3.93, 5.20 +/- 1.46, and 4.95 +/- 1.27; p < 0.05). There was a significant correlation between TNF-alpha and sIL-2R in patients before montelukast treatment (r = 0.674; p < 0.01). This study indicates that montelukast improves clinical parameters and shows anti-inflammatory response by decreasing serum sIL-2R and TNF-alpha levels.

Abstract
UNLABELLED The efficacy of montelukast, a leukotriene receptor antagonist, in treatment of mild asthma was evaluated. METHODS Thirty children aged 6 to 14 years with mild persistent asthma (asthma history more than 12 months and > or = 15% FEV1 improvement after inhaled beta 2-agonist in the past, good control of asthma with inhaled cromolyn or budesonide in the last three months) were enrolled. The study included three periods (2 week's each): washout, placebo, and montelukast. Asthma symptoms score (range 0-5) and PEF were estimated twice daily by children. Spirometric parameters FEV1 and MEF50 were measured during three consecutive visits: on the day of study inclusion, on the last day of the placebo and montelukast period. RESULTS The mean value of asthma symptoms score was significantly lower during the montelukast period in comparison with placebo (p = 0.038). The mean PEF values were significantly higher during the montelukast vs. placebo period (p = 0.0091). Moreover, in the montelukast period, the mean PEF values in the second week were significantly higher than those in the first week (p = 0.003). The mean FEV1 predictive value in the last day of the montelukast period was higher, though not significantly, than on the day of study inclusion and on the last day of the placebo period. A similar change in mean MEF50 values was observed. CONCLUSION In children aged 6-14 years with mild persistent asthma, montelukast treatment significantly diminishes asthma symptoms and increases mean PEF values comparing to placebo.
