PURPOSE: Recent studies have shown that the cysteinyl leukotriene (cysLT) of exhaled breath condensate (EBC) could be predictive of inflammatory status and effectiveness of treatment in allergic disease. The aim of this study was to evaluate the inflammation and therapeutic effectiveness of cysLT in EBC in pediatric patients with allergic rhinitis (AR). METHODS: We enrolled 34 healthy children (median age, 4 years 10 months) and 67 AR children (median age, 5 years 1 month). All of the AR patients received intranasal steroid (fluticasone furoate) once daily for 2 weeks. After 2 week of fluticasone furoate treatment, they were classified into 2 groups: the fluticasone furoate (F) and montelukast (M) groups. We treated each group for another 8 weeks. To evaluate the therapeutic effectiveness, we used symptom score (SS) and EBC leukotriene E4 (LTE4). EBC samples were collected with RTube. Each parameter was checked at 0, 2, and 10 weeks of therapy. RESULTS: Most of the AR patients showed clinical improvement with 2- and 10-week fluticasone therapy (F group: 0-week SS, 5.6; 2-week SS, 3.6; 10-week SS, 2.1; P<0.01; M group: 0-week SS, 4.8; 2-week SS, 3.2; 10-week SS, 1.9: P<0.01). LTE4 levels were higher in AR patients than in control subjects (0 week: 87 pg/mL vs. 18 pg/mL) and were reduced after 2 weeks of fluticasone treatment (F group: 90→51.6 pg/mL, P<0.01; M group: 84→46.1 pg/mL, P<0.01). After 10 weeks of treatment, there was no significant difference in the LTE4 level between the F and M groups. CONCLUSION: LTE4 in EBC may be useful for evaluating inflammation and therapeutic effectiveness in patients with allergic rhinitis.

BACKGROUND: Corticosteroid is most potent and effective anti-inflammatory medication currently available and inhaled form has been used in the long-term control of asthma. Fluticasone propionate(Flixotide/Flovent : FP) is highly potent and topically active inhaled corticosteroid and has at least twice the potency of beclomethasone dipropionate(BDP) in the control of asthma. The aim of this study was to compare the efficacy of FP and BDP in several aspects. METHOD: Fifty patients with asthma were treated in a randomized, parallel group study of 4 weeks duration. During 2-week run-in period beta2-agonist was administered. After run-in period, FP 500 micro gram/day was administered via Diskhaler or BDP 800 micro gram/day via reservoir dry-power device. During the run-in and treatment period, morning and evening peak expiratory flow rate(PEFR) were measured daily. Daytime and night-time asthma symptoms, daytime and night-time rescue bronchodilator use were checked daily. FEV1.0 and FVC were measured biweekly in both groups. RESULTS: Three patients treated with FP and seven patient treated with BDP were dropped out. Therefore forty patients completed the study. Morning and evening PEFR was increased and diurnal variation of PEFR decreased significantly in both groups. FEV1.0 increased significantly in FP treatment group but not in BDP group. There were also improvements in daytime and night-time asthma symptoms, daytime and night-time rescue bronchodilator use in both groups after treatment. there were no significant difference between groups in any of the efficacy parameters. Therapeutic effects were dimonstrated earlier in patient treated with FP than BDP. CONCLUSION: In this study, 500 micro gram/day fluticasone propionate was as effective as 800 micro gram/day beclomethasone dipropionate in the control of asthma. Therapeutic effects were demonstrated earlier in patient treated with FP than BDP without adverse effect.

fluticasone nasal spray (two sprays in each nostril once daily). Olfactory function was evaluated at baseline and again at three months, and results were quantified as patient TDI (threshold, discrimination, and identification) scoreRESULTS: Olfactory function improved in 74 of 134 patients (55.2%). Etiology of olfactory disorder, sex, and age had statistically significant influence on the improvement rate of olfactory function, among which etiology of olfactory loss was the most important. However, initial severity and duration of olfactory loss had no statistically significant influence on the improvement rate. The TDI score at three months of olfactory training showed remarkable improvement, primarily because of improvements in the discrimination and identification components.CONCLUSION: The present study showed that olfactory training with intranasal corticosteroid was beneficial to improve olfactory function in patients with olfactory dysfunction, particularly in postviral infection patients.]]>

Nasal polyp is an intractable condition usually associated with chronic hyperplastic sinusitis with allergic rhinitis. IL-4 is known to contribute to the inflammatory reaction by enhancing binding of inflammatory cells in the nasal polyp. The objectives of this study were to evaluate the effect of roxithromycin (300 mg daily) and intranasal fluticasone spray (200 microgram daily ) in reducing symptoms of chronic sinusitis and polyp size and to compare pre - and post-treatment secretion of IL-4. Twenty-four patients with chronic sinusitis with nasal polyp and allergic rhinitis were selected and allocated into 3 groups ; roxythromycin, fluticasone propionate and combined use group. Statistically significant decrease in symptoms was observed in both the roxythromycin and fluticasone propionate groups. Significant improvement of rhinorrhea and postnasal drip was observed in the combined use group. The polyp size decreased significantly in all three groups. IL-4 secretion decreased significantly in the combined use group after treatment. Long term medication of roxithromycin and intranasal fluticasone spray were effective in reducing symptoms and polyp size in chronic sinusitis with allergic rhinitis. They were also effective in reducing IL-4.

PURPOSE: We aim to compare the effectiveness and safety of fluticasone propionate (Flt) plus tulobuterol (Hk) versus high-dose Flt alone in controlling asthma in children. METHODS: Fifty three children aged 4 to 8 years, who were diagnosed with mild persistent asthma and underwent maintenance therapy with a low dose of inhaled corticosteroid (Flt) of 50-100 microgram/day were randomized to receive Flt plus Hk (Hokunalin(R) patch 1 mg, Abbott Japan, Tokyo, Japan), or Flt alone at twice the dosage. Patients underwent new treatment for 4 weeks. Asthma symptom scores, mean changes in morning and evening peak expiratory flow (PEF), the frequency of night awakenings, the use of reliever medication, caregiver's overall satisfaction and safety were evaluated and compared in each group. And they were followed-up again 4 week after treatment course for the evaluation of treatment-emergent adverse event (TEAE). RESULTS: No significant difference was found between the groups in terms of mean changes in the morning and evening PEF, the frequency of night awakening, the use of rescue medication and caregiver's overall satisfaction (P=0.83, P=0.83, P=0.17, P=0.32 and P=0.63). Furthermore, no statistically significant difference was observed between 2 groups in the incidence of any TEAE (P=1.00). CONCLUSION: This study demonstrated that a combination of Flt and Hk was as effective as a high-dose Flt therapy in the management of mild persistent asthma in children. The results of this study suggest that tulobuterol add-on therapy can be considered as a reasonable substitute to an increase in the dosage of steroid in the patients with steroid-phobia and it might be used to reduce the risk of high dose steroid therapy.

PURPOSE: The of this study was to describe the changes of airway inflammation in children with stable, steriod naive asthma after inhaling fluticasone by using serial induced sputum. We sought to investigate the role of neutrophils, interleukin-8(IL-8), and myeloperoxidase(MPO) in asthma. METHOD: To examine the change of neutrophil and their products in childhood asthma after inhaling fluticasone, we assessed the cell counts, IL-8, and MPO in the sputum at each visit. Also, the daily symptom scores, FEV1, peak expiratory flow variability, and methacholin airway responsiveness were checked and their relationships were analyzed. RESULT: There was a significant improvement in asthma severity, as measured by symptom score, and FEV1. There were significant reductions in IL-8 and MPO after 3 weeks treatment, and significant increase in the total sputum cell counts. Significant increase in total lymphocyte and alvelor macrophage cell counts with no increase in neutrophil and eosinophil counts were found. Airway responsiveness was significantely correlated with total eosinophil counts before inhaling fluticasone and it was correlated with IL-8 after the treatment. CONCLUSION: This study highlight, the probable importance of IL-8 and myeloper-oxidase within the asthmatic airways and the beneficial modulatory effect of inhaled fluticasone treatment upon them.

PURPOSE: The efficacy of intranasal corticosteroids for the treatment of allergic rhinitis has been reported. But the efficacy of intranasal corticosteroids has not been compared between perennial nonallergic rhinitis (PNAR) and perennial allergic rhinitis (PAR). METHODS: Twenty-three patients with PNAR and 19 patients with PAR were enrolled in this study. Every patient received fluticasone propionate (FP) 200 g (100 g, bid) daily for 4weeks. Control group (n=16) was received only anti-histamine (hydroxyzine 0.6 mg/kg/dose) intermittently. Efficacy of FP was evaluated by the mean change in nasal congestion, rhinorrhea, nasal itching, sneezing and total nasal symptom score (a sum of patient ratings of nasal congestion, rhinorrhea, nasal itching, and sneezing). RESULTS: Both groups (PNAR and PAR) showed similar improvement of nasal symptom with FP 200 g compared with control. (P< 0.05) In the total population, both groups showed significant improvements from baseline in TNSS compared with control during each week of treatment. (P< 0.05) In PNAR and PAR, nasal congestion was significantly improved more than in control. (P< 0.01, P< 0.01) Rhinorrhea and itching in PAR were improved more than in control. (P=0.02, P=0.03) In sneezing, all three groups showed no differences. (P=1.00, P=0.31, P= 0.29) CONCLUSION: Intranasal FP is an effective treatment for perennial nonallergic rhinitis as same as perennial allergic rhinitis.

BACKGROUND: The discomfort caused by chronic cough, that is persistent for more than 3 weeks, causes a number of patients to seek medical attention. However, the underlying disorder often remains undetermined despite thorough examinations, and is considered to be idiopathic. This study compared the efficacy of inhaled corticosteroid with conventional cough suppressants on chronic idiopathic cough. METHODS: Eligible patients with chronic idiopathic cough were randomly assigned to either the inhaled fluticasone group or the codeine plus levodropropizine oral administration group. The subjects in each group took their planned medication for 2 weeks. After the trial, comparative analyses of outcomes were performed in terms of the remnant cough (%) at the end of treatment, drug compliance, and adverse drug events. RESULTS: Seventy-seven patients were enrolled in this randomized trial; 38 to the inhaled fluticasone group and 39 to the codeine plus levodropropizine group. The remnant cough was 41.0+/-35.8% in the inhaled fluticasone group, and 32.4+/-32.0% in the codeine+levodropropizine group (p=0.288). Drug compliance was 95.4+/-7.4% and 81.8+/-18.6% in the inhaled fluticasone and the codeine+levodropropizine group, respectively (p<0.001). Nine patients had adverse drug events in the codeine+levodropropizine group compared to one in the inhaled fluticasone group (p<0.001). CONCLUSION: Short-term inhaled corticosteroid is not inferior to conventional antitussive agents in controlling chronic idiopathic cough without significant adverse events.

BACKGROUND: To compare the profiles of the bronchodilator response (BDR) among children with asthma and/or allergic rhinitis (AR) and to determine whether BDR in these children is reduced by treatment with inhaled and/or nasal corticosteroid. METHODS: Sixty-eight children with asthma (mean age, 10.9 years), 45 children with comorbid asthma and AR (mean age, 10.5 years), and 44 children with AR alone (mean age, 10.2 years) were investigated. After a 2-week baseline period, all children were treated with inhaled fluticasone propionate (either 100 or 250 microg b.i.d., tailored to asthma severity) or nasal fluticasone propionate (one spray b.i.d. in each nostril) or both, according to the condition. Before and 2 weeks after starting treatment, all children were evaluated with spirometry and bronchodilator testing. BDR was calculated as a percent change from the forced expiratory volume in 1 second (FEV1) at baseline. RESULTS: The mean BDR was 10.3% [95% confidence interval (CI) 8.3-12.4%] in children with asthma, 9.0% (95% CI 7.3-10.9%) in subjects with asthma and AR, and 5.0% (95% CI 4.1-5.9%) in children with AR alone (P<0.001). After treatment, the mean BDR was reduced to 5.2% (95% CI 4.2-6.3%) (P<0.001) in children with asthma and to 4.5% (95% CI 3.5-5.5%) (P<0.001) in children with asthma and AR. However, children with rhinitis showed no significant change in BDR after treatment, with the mean value being 4.7% (95% CI 3.7-5.8%) (P=0.597). CONCLUSION: The findings of this study imply that an elevated BDR in children with AR cannot be attributed to nasal inflammation alone and highlights the close relationship between the upper and lower airways.
