fluticasone and Acute-Disease

The present study aimed to assess the prevalence of symptoms of anxiety and depression among health professionals in the three most affected regions in Cameroon.. The study was a descriptive cross-sectional type. Participants were health care professionals working in the three chosen regions of Cameroon. The non_probability convinient sample technique and that of the snowball were valued via a web questionnaire. The non-exhaustive sample size was 292. The diagnosis of anxiety and depression was made by the HAD (Hospital Anxiety and Depression scale).. Les auteurs rapportent que le secteur médical est classé à un plus grand risque de contracter le COVID-19 et de le propager potentiellement à d’autres. Le nombre sans cesse croissant de cas confirmés et suspects, la pression dans les soins, l’épuisement des équipements de protection individuelle et le manque de médicaments spécifiques peuvent contribuer à un vécu anxio-dépressif significatif. La présente étude s’est donnée pour ambition d’évaluer la prévalence des symptômes de l’anxiété et de la dépression chez les professionnels de santé dans les trois Régions les plus concernées au Cameroun.. Le choix des trois Régions du Cameroun se justifie non seulement par le fait qu’elles totalisent 95,8 % des cas de coronavirus au pays depuis le début de la pandémie, mais aussi parce qu’elles disposent de plus de la moitié des personnels de santé (56 %). Il s’agit d’une étude transversale, descriptive et analytique. Les participants sont des professionnels de la santé en service dans les Régions du Centre, Littoral et de l’Ouest du Cameroun. La méthode d’échantillonnage non probabiliste de convenance couplée à celle de boule de neige via un web questionnaire a été adoptée. La collecte des données a duré du 5 au 19 avril 2020, intervalle de temps après lequel on n’avait plus eu de répondants. À la fin de cette période, la taille de l’échantillon non exhaustive était de 292 professionnels. Le diagnostic de l’état anxio-dépressive était posé via l’échelle de HAD (Hospital Anxiety and Depression scale). Dans le HAD, chaque réponse cotée évalue de manière semi-quantitative l’intensité du symptôme au cours de la semaine écoulée. Un score total est obtenu ainsi que des scores aux deux sous-échelles : le score maximal est de 42 pour l’échelle globale et de 21 pour chacune des sous-échelles. Le coefficient alpha de Cronbach est de 0,70 pour la dépression et de 0,74 pour l’anxiété. Certains auteurs après plusieurs travaux ont proposé qu’une note inférieure ou égale à 7 indique une absence d’anxiété ou de dépression ; celle comprise entre 8 et 10 suggère une anxiété ou une dépression faible à bénigne ; entre 11 et 14, pour une anxiété ou une dépression modérée ; enfin, une note comprise entre 15 et 21 est révélatrice d’une anxiété sévère.

Taken together with satisfactory selectivity index (SI) values, the acetone and methanol extracts of. During a mean follow-up period of 25.6 ± 13.9 months, 38 (18.4%) VAs and 78 (37.7%) end-stage events occurred. Big ET-1 was positively correlated with NYHA class (. In primary prevention ICD indication patients, plasma big ET-1 levels can predict VAs and end-stage events and may facilitate ICD-implantation risk stratification.. Beyond age, cognitive impairment was associated with prior MI/stroke, higher hsCRP, statin use, less education, lower eGFR, BMI and LVEF.. These data demonstrate that even a short period of detraining is harmful for elderly women who regularly participate in a program of strength training, since it impairs physical performance, insulin sensitivity and cholesterol metabolism.. Exposure to PM. Respiratory sinus arrhythmia is reduced after PVI in patients with paroxysmal AF. Our findings suggest that this is related to a decrease in cardiac vagal tone. Whether and how this affects the clinical outcome including exercise capacity need to be determined.. BDNF and leptin were not associated with weight. We found that miR-214-5p exerted a protective role in I/R injured cardiac cells by direct targeting FASLG. The results indicated that the MGO injection reduced all CCl. The hepatoprotective effects of MGO might be due to histopathological suppression and inflammation inhibition in the liver.. OVEO showed moderate antifungal activity, whereas its main components carvacrol and thymol have great application potential as natural fungicides or lead compounds for commercial fungicides in preventing and controlling plant diseases caused by. PF trajectories were mainly related to income, pregestational BMI, birth weight, hospitalisation due to respiratory diseases in childhood, participant's BMI, report of wheezing, medical diagnosis and family history of asthma, gestational exposure to tobacco and current smoking status in adolescence and young adult age.. In chronic pain patients on opioids, administration of certain benzodiazepine sedatives induced a mild respiratory depression but paradoxically reduced sleep apnoea risk and severity by increasing the respiratory arousal threshold.. Quantitative measurements of sensory disturbances using the PainVision. The serum level of 20S-proteasome may be a useful marker for disease activity in AAV..

Adverse events (AEs) associated with short-term corticosteroid use for respiratory conditions in young children.. Systematic review of primary studies.. Medline, Cochrane CENTRAL, Embase and regulatory agencies were searched September 2014; search was updated in 2017.. Children <6 years with acute respiratory condition, given inhaled (high-dose) or systemic corticosteroids up to 14 days.. One reviewer extracted with another reviewer verifying data. Study selection and methodological quality (McHarm scale) involved duplicate independent reviews. We extracted AEs reported by study authors and used a categorisation model by organ systems. Meta-analyses used Peto ORs (pORs) and DerSimonian Laird inverse variance method utilising Mantel-Haenszel Q statistic, with 95% CI. Subgroup analyses were conducted for respiratory condition and dose.. Eighty-five studies (11 505 children) were included; 68 were randomised trials. Methodological quality was poor overall due to lack of assessment and inadequate reporting of AEs. Meta-analysis (six studies; n=1373) found fewer cases of vomiting comparing oral dexamethasone with prednisone (pOR 0.29, 95% CI 0.17 to 0.48; I. Evidence suggests that short-term high-dose inhaled or systemic corticosteroids use is not associated with an increase in AEs across organ systems. Uncertainties remain, particularly for recurrent use and growth outcomes, due to low study quality, poor reporting and imprecision.

In chronic obstructive pulmonary disease (COPD), the rate of decline in forced expiratory volume in 1 second (FEV1) and progression to disability and death are accelerated. COPD management goals include preventing or slowing the progressive loss of lung function, relieving symptoms, improving exercise tolerance and the patient's health status, preventing and treating exacerbations and complications, minimizing side effects of treatment, and reducing mortality. Although lung function is important for diagnosis of COPD and classification of its severity, clinicians and patients are also very interested in symptoms, ability to function, and general well-being (health status). Consequently, increasing attention is being given to these patient-centered outcomes. It is possible to modify patient-centered outcomes; however, it remains to be seen whether doing so can also alter the natural course of the disease and reduce mortality. Two long-term clinical trials--Towards a Revolution in COPD Health (TORCH) and Understanding the Potential Long-Term Impacts on Function with Tiotropium (UPLIFT)--will help to answer the question of whether pharmacologic interventions are effective in changing the clinical course of COPD. The TORCH study examines the long-term effects of combination therapy with an inhaled long-acting beta-agonist (salmeterol) and a corticosteroid (fluticasone) on reduction of all-cause mortality over 3 years. The 4-year UPLIFT study examines the effects of maintenance treatment with the once-daily anticholinergic bronchodilator tiotropium on the yearly rate of decline in trough FEV1 and the yearly rate of decline in FEV1 90 minutes after maximal or near-maximal bronchodilator administration. This article examines the rationale for each of these studies and provides an overview of study methodology as well as preliminary demographic data.

Oral corticosteroids (CS) are standard treatment for patients discharged from the emergency department (ED) after treatment for acute asthma. Several recent, relatively small trials have investigated the replacement of CS with inhaled corticosteroids (ICS), with varied results and conclusions. This systematic review examined the effect of using ICS in place of CS on outcomes in this setting.. Only randomized controlled trials were eligible for inclusion. Studies in which patients were treated for acute asthma in the ED or its equivalent, and on discharge compared ICS therapy to standard CS therapy, were eligible for inclusion. Trials were identified using the Cochrane Airways Review Group register, searching abstracts and bibliographies, and contacting primary authors and pharmaceutical companies. Data were extracted and methodologic quality assessed independently by two reviewers, and missing data were obtained from authors.. Seven trials, involving a total of 1,204 patients, compared high-dose ICS therapy vs CS therapy after ED discharge. There were no significant differences demonstrated between the treatments for relapse rates (odds ratio, 1.00; 95% confidence interval, 0.66 to 1.52) or in the secondary outcomes of beta-agonist use, symptoms, or adverse events. However, the sample size was not adequate to prove equivalence between the treatments, and severe asthmatics were excluded from these trials.. There is some evidence that high-dose ICS therapy alone may be as effective as CS therapy when used in mild asthmatics on ED discharge; however, there is a significant possibility of a type II error in drawing this conclusion.

Intranasal corticosteroids (INS) have been proven effective in controlling postnasal drip, decreasing inflammatory response, reducing nasal swelling, and increasing aeration of the sinuses such that INS are recommended as treatment of sinusitis.. Fifty children with acute rhinosinusitis, 50 children with acute rhiniosinusitis and allergic rhinitis (AR), and 20 rhiniosinusitis children as control were selected for investigation. Each group had a single-blind treatment of three types: with coamoxiclav only, with coamoxiclav plus INS, and with matched placebo (without antibiotics and INS) for two weeks. Nasal symptoms were then evaluated. The outcome was measured by using major symptom score (MSS) after treatment for 14 days.. Therapeutic effectiveness was 92% in rhinosinusitis patients treated with co-amoxiclav and 84% in those treated with co-amoxiclav plus INS. Among patients with sinusitis combined with AR, therapeutic efficacy was 88% for those treated with co-amoxiclav and 96% for those treated with co-amoxiclav plus INS. Only 30% of the symptoms were reduced in the placebo group.. There are no statistical differences in the acute sinusitis group treated with co-amoxiclav with or without INS. In the sinusitis with AR group, the efficacy of co-amoxiclav with INS is higher than in children treated with co-amoxiclav alone.

Fluticasone propionate and nasal saline irrigation have been used in the treatment of sinonasal diseases for a long time. Our study investigates the effect of the combination of large volume low pressure nasal saline irrigation and fluticasone propionate for the treatment of pediatric acute rhinosinusitis.. Ninety-one pediatric patients with acute rhinosinusitis were included in our study. The patients were randomized into two groups. The first group (n=45) was treated with standard therapy (antibiotherapy+nasal decongestant) for 2 weeks, the second group was treated with the large volume low pressure nasal saline+fluticasone propionate combination for 3 weeks. The clinical scores, radiologic evaluations (X-ray Waters view), peak nasal inspiratory flow (PNIF) measurements, total symptom scores and hematologic parameters (WBC, CRP, ESR) of the patients were evaluated and compared.. There were no significant differences in between the two groups regarding age, gender, height and weight. Even though the clinical scores of Group 2 improved more rapidly, there were no significant differences in between groups regarding clinical scores by the 21st day. There were no significant differences in post treatment radiologic evaluations (Waters graphy). Both groups had significant improvement of their post treatment PNIF values, yet the improvement was more marked in Group 2 than in Group 1. The rhinorrhea, nasal congestion, throat itching and cough symptoms improved more rapidly in Group 2 than in Group 1. Post-treatment nose itching and sneezing symptoms were significantly less in Group 2. The values of hematologic parameters were significantly reduced at the end of the 3rd week in both groups.. Our study is a first in investigating the combined use of large volume low pressure nasal saline and fluticasone propionate in acute pediatric rhinosinusitis, and the results reveal that the combination therapy was effective. Low pressure large volume nasal saline+fluticasone propionate combination can be employed as a new line of therapy for the treatment of pediatric acute rhinosinusitis, either by itself or combined with standard therapy.

Approximately 0.5-2% of upper respiratory tract infections in adults and 6-13% of viral upper respiratory tract infections in children are complicated by acute sinusitis. This study was aimed to evaluate the coadministration effect of fluticasone nasal spray (FNS) with amoxicillin for AS in children.. One hundred children 2 to 14 years of age with acute sinusitis referred to Shahid Mohammadi Pediatric Hospital in Bandar Abbas were randomly allocated into two equal intervention and control groups to receive amoxicillin with fluticasone nasal spray one puff twice daily for 14 days and amoxicillin 80 to 100 mg/kg/ day for 14 days respectively.. Twenty one (42%) of children in intervention group were cured completely and 2 (4%) children in control group had complete recovery (p < 0.001). Symptom severity score was 22.98 ± 2.95 before treatment that reduced to 13.26 ± 3.20 after treatment (p < 0.001).. Use of fluticasone can reduce the severity of symptoms of sinusitis in children.

The role of inhaled corticosteroids in the treatment of acute asthma exacerbations in children is controversial. This study compared the effect of inhaled budesonide and inhaled fluticasone in controlling acute asthma exacerbations in young children at home.. In a quasi-randomized crossover design, children aged 5 months to 5 years with severe recurrent asthma episodes were treated either with inhaled budesonide 200 mcg or inhaled fluticasone 125 mcg delivered with a similar spacer. At the onset of asthma exacerbations, 2 puffs of inhaled terbutaline followed by inhaled budesonide or fluticasone was administered using one of the following treatment protocols: 1 4-day protocol for a relatively mild exacerbation; 2 8-day protocol for exacerbations that were more severe or uncontrolled by the 4-day protocol; and 3 8-day protocol + azithromycin for exacerbations uncontrolled by the 8-day protocol or possibly associated with infection with atypical agents. Children were followed for 2 months after each exacerbation. Good response was defined as the absence of asthma symptoms for at least 2 weeks from completion of treatment.. One hundred children were recruited: 36 were treated with budesonide, 21 with fluticasone, and 44 with both on different occasions. The groups were similar for preliminary data. Good response was noted in 87% of the budesonide group, 85% of the fluticasone group, and 86% of the budesonide/fluticasone group. By protocol, rates of good response were 84%, 83%, and 94% for the 4-day, 8-day, and 8-day+azithromycin treatment protocols, respectively; corresponding symptom-free periods after treatment were 4.0, 4.9, and 4.3 weeks. None of the children received oral corticosteroids.. Acute asthma exacerbations in young children can be effectively controlled at home with the use of high repetitive doses of inhaled budesonide or inhaled fluticasone, initially together with beta(2)-agonists, given at the beginning of the attack, for a period of 4-8 days.

The aim of this study was to evaluate whether fluticasone propionate (FP) is effective as well as prednisone (P) in reducing sputum eosinophilia and in improving airway obstruction due to asthma exacerbations not requiring hospitalization. We measured, in a parallel-group, double-blind double-dummy, randomized study, sputum and blood inflammatory cell counts and soluble mediators in 37 asthmatic subjects during a spontaneous exacerbation of asthma (Visit 1) and after a 2 week (Visit 2) treatment with inhaled FP (1000microg bid) (Group A, n=18) or a reducing course of oral P (Group B, n=19). Asthma exacerbation was accompanied by sputum eosinophilia (eosinophils >2%) in almost all patients (95%). FP improved FEV(1) (from 53.9%+/-16.8 at Visit 1 to 76.4%+/-21.2 at Visit 2, p=0.0001) and reduced the percentage of sputum eosinophils (from 38%[0-78] to 3%[1-31, p=0.0008) as well as oral P (FEV(1): from 51.5%+/-14.4 to 83.6%+/-21.1, p=0.0001; sputum eosinophils: from 52%[1-96] to 11%[0-64], p=0.0003). At Visit 2, sputum eosinophils were significantly lower in Group A than in Group B. P but not FP induced significant decrease in blood and sputum ECP. Oxygen saturation, PEF variability, symptom score and use of rescue medication similarly improved in both groups. We conclude that FP is effective at least as well as P in reducing sputum eosinophilia and in improving airway obstruction due to asthma exacerbation. However, the cost/effectiveness ratio of this option should be further evaluated.

Several studies published in the second half of the 1990s have shown a therapeutic early effect of inhaled corticosteroids in acute asthma. However, systemic corticosteroids are considered the standard of care.. To compare the effect of repeated doses of inhaled fluticasone with the standard treatment of systemic corticosteroids in adult patients with severe acute asthma.. One hundred six patients (mean age, 33.5 +/- 8.8 years) were randomly assigned to receive fluticasone (3,000 microg/hour) administered through a metered-dose inhaler and spacer at 10-minute intervals for 3 hours, or 500 mg of intravenous hydrocortisone. In addition, all patients received inhaled albuterol and ipratropium bromide.. Subjects treated with fluticasone showed 30.5 and 46.4% greater improvements in PEF and FEV1, respectively, compared with the hydrocortisone group. The fluticasone group had better PEF and FEV1 at 120, 150, and 180 minutes (p < 0.05). Also, the fluticasone group showed higher rates of patients who obtained the discharge threshold at 90, 120, and 150 minutes. This therapeutic benefit was particularly evident in those patients with the most severe obstruction. Subjects with a baseline FEV1 of less than 1 L treated with fluticasone showed a significant increase in pulmonary function (p = 0.001) and a significant decrease in hospitalization rate (p = 0.05).. The use of repeated doses of inhaled fluticasone was more effective than intravenous hydrocortisone and was associated with an early improvement. This therapeutic benefit was particularly evident in those patients with the most severe obstruction.

Little is known about the longitudinal changes in the ciliated respiratory epithelium of infants following viral bronchiolitis. A study was undertaken to investigate the time required for the ciliated epithelium to return to normal following bronchiolitis in infants treated with inhaled steroids or placebo.. Thirty one previously healthy term infants were studied as part of a clinical trial to determine the effect of 12 weeks of treatment with inhaled fluticasone (FP) or placebo via a spacer device (17 FP, 14 placebo). Nineteen healthy children aged 0-6 years previously studied in our department were used as controls. Nasal biopsy specimens were taken from infants with bronchiolitis and ciliary beat frequency (CBF) was measured before treatment and repeated 3, 6, 12, and 24 weeks later. The epithelial ultrastructure was examined by transmission electron microscopy and a normal errors mixed model based on normal controls was used to examine the time for cilia to return to normal in bronchiolitic infants.. The mean CBF of infants with bronchiolitis (in Hz) at weeks 0, 3, 6, 12, and 24 were 0.5 (n = 4), 10.9 (n = 4), 12.0 (n = 9), 11.9 (n = 8), and 12.1 (n = 7) in the placebo group and 10.6 (n = 6), 11.4 (n = 9), 8.8 (n = 8), 10.9 (n = 4), and 13.2 (n = 7) in the FP group. The time for the epithelial ultrastructure to normalise was as follows: epithelial integrity score (13.1 weeks), % ciliated cells with loss of cilia (14.0 weeks), and % epithelial cells with abnormalities in projection (16.7 weeks) or mitochondria (15.9 weeks). Inhaled steroids had no significant effects on CBF or epithelial ultrastructure.. Ciliary loss and epithelial abnormalities persist on average for 13-17 weeks following acute bronchiolitis in infancy.

Two multicentre, randomised, parallel group, double-blind, comparative studies in children (2-14 yr) evaluated fluticasone propionate (FP) 0.05% cream for both acute and maintenance treatment of moderate to severe atopic dermatitis (AD).. One study compared FP with hydrocortisone (HC) 1% cream (FP 70, HC 67) and the other with hydrocortisone butyrate (HCB) 0.1% cream (FP 67, HCB 62). Treatments were applied twice daily, for 2-4 weeks until the AD was stabilised, and thereafter intermittently ('as required') for up to 12 weeks.. The primary outcome measure, Total AD Score, recorded at the end of the acute and maintenance phases, was significantly lower (indicating improvements in disease severity) following treatment with FP compared with either HC or HCB (acute phase difference vs. HC, -2.39, 95%CI -3.47, -1.31; p<0.001 and vs. HCB, -1.25, 95%CI -2.46, -0.05; p=0.042) and (maintenance phase difference vs. HC, -1.88, 95%CI -3.20, -0.56; p=0.006 and vs. HCB, -1.39, 95%CI -2.72, -0.05; p=0.042). In both studies treatments were equally well tolerated with no visible signs of skin atrophy.. In both the acute and longer term management of AD in children, FP demonstrated a high level of efficacy and maintenance of disease control with a tolerability similar to HC 1%, a lower potency corticosteroid.

Inhaled corticosteroids are often used in the treatment of stable chronic obstructive pulmonary disease (COPD), however, studies of these agents have had mixed results. Previous trials have often excluded subjects with bronchodilator response, have failed to evaluate effect on gas exchange, and have usually looked at only post- rather than prebronchodilator forced expiratory volume (FEV). Our objective was to better assess the efficacy of topical corticosteroids in the treatment of COPD. We used a prospective, randomized, double-blinded, placebo-controlled, crossover study at the Outpatient Department, Department of Veterans Affairs Medical Center. Thirty-six COPD patients with a mean (+/- SD) FEV1 of 1.10 +/- 0.43 L, with or without significant bronchodilator response participated in the study. Subjects received a 3-month course of inhaled fluticasone propionate (220 micro g/puff) or identical-appearing placebo by metered-dose inhaler at 2 puffs twice daily, followed by crossover to the alternative inhaler for an additional 3 months. Fluticasone treatment resulted in a higher prebronchodilator FEV1 (1.17 +/- 0.08 L [mean +/- SEM] versus 1.07 +/- 0.08 L, p = 0.001), a higher PaO2 (66.6 +/- 1.4 mmHg versus 63.6 +/- 1.6 mmHg, p = 0.002), and a better dyspnea score on the chronic respiratory questionnaire (3.70 +/- 0.18 versus 3.47 +/- 0.19, p = 0.03). A trend towards fewer exacerbations with fluticasone did not quite meet statistical significance (p = 0.11). Inhaled fluticasone over 3 months improved prebronchodilator airflow obstruction and oxygenation while decreasing dyspnea in moderate to severe COPD. Postbronchodilator FEV1 was not significantly changed.

Inhaled corticosteroids have been used with variable success in sarcoidosis. The role of the inhaled corticosteroid fluticasone in symptomatic pulmonary patients was studied.. Twenty-two patients at five institutions who had been given an initial dose of oral corticosteroids within the prior four weeks were enrolled in a randomized double blind trial of inhaled fluticasone. An algorithm for the dosage of prednisone including rules for reducing dose was developed and applied at all centers.. Of the 21 patients seen for more than one visit, 10 received fluticasone and 11 placebo. There was no significant difference in the improvement of vital capacity or average daily dose of prednisone for the fluticasone versus placebo. Eight of ten patients taking fluticasone had improvement in cough, while only 6 of 11 patients on placebo had improved cough despite taking oral corticosteroids (p = 0.36, N.S.). The algorithm for decreasing corticosteroid dosage was exactly applied in over 80% of patient visits and oral corticosteroids were used throughout most of the year of treatment. Patients registered higher complaints regarding increased appetite and polyuria when on ten mg or more prednisone a day. There was no clinical difference in the rate of toxicity for the fluticasone versus placebo group.. A standard approach to tapering oral corticosteroids was followed in over 80% of patient visits. Oral corticosteroids were associated with significant complaints, while inhaled corticosteroids were well tolerated.

Information on the dose of steroid infants inhale from spacer devices and its potential effect on adrenal suppression is limited.. We sought to determine the total dose of fluticasone propionate (FP) inhaled from a spacer device (Babyhaler) with face mask attachment by infants recovering from acute bronchiolitis and the effect of inhaled FP on the infants' overnight urinary cortisol/creatinine ratios (UCCRs).. Infants studied were recovering from acute bronchiolitis. In study 1, 22 infants inhaled 150 microg of FP through the Babyhaler. The likely inhaled dose was estimated by trapping it on a filter held within the face mask. In study 2, 40 infants had UCCRs measured before and during 3 months of treatment with either FP (150 microg twice daily, n = 20) or placebo (n = 20).. In study 1 the mean +/- SD dose of captured FP was 12.8 +/- 6.9 microg (ie, 2.1 +/- 1.2 microg/kg). In study 2 the pretreatment UCCR medians (interquartile ranges) were as follows: FP, 22.8 (23.0) nmol/mmol; placebo, 24.0 (28.3) nmol/mmol. Within-group UCCR changes (median and interquartile range DeltaUCCR) were significantly different in the FP group (-8.9 and -20.6 nmol/mmol at 6 weeks and -12.6 and -25.9 nmol/mmol at 12 weeks, respectively; P =.0008) but not in the placebo group ( -5.8 and -10.7 nmol/mmol at 6 weeks and +0.3 and -17.9 nmol/mmol at 12 weeks, respectively; P =.45). Intergroup changes were insignificant in the follow-up period (6 weeks, P =.52; 12 weeks, P =.19).. After bronchiolitis, infants are likely to inhale approximately 8 % of the nominal steroid dose from the Babyhaler. UCCRs can be used to monitor the bioavailability of inhaled steroids in young infants.

The aims of the study were to determine: 1) how mucociliary activity in acute bacterial rhinosinusitis is affected; 2) how this activity is changed by therapy; 3) the effects of topical agents on mucociliary clearance, and 4) the most appropriate topical agent(s) to be used in the therapy of sinusitis.. Five groups of patients with acute bacterial rhinosinusitis were studied prospectively.. All patients had 500 mg oral amoxicillin and 125 mg oral clavulanic acid preparations given three times daily for 3 weeks. According to the topical agent applications, these groups included: group I (n = 12), no topical treatment was given; group II (n = 14), two puffs for each nostril once daily of 50 microg/100 mL fluticasone propionate was given; group III (n = 9), one puff for each nostril three times daily of 0.05% oxymetazoline was given; group IV (n =12), 3% sodium chloride (NaCl) (buffered to pH 6.5-7 at room temperature) was given; and group V (n =13), 10-mL solutions of 0.9% NaCl (buffered to pH 6.5--7 at room temperature) were given for nasal irrigations three times daily. All patients had medication for 3 weeks and were controlled each week. The saccharin method was used to measure nasal mucociliary clearance. To investigate the early effects of the topical agents for groups II to V, an additional test was repeated 20 minutes after the basal mucociliary clearance recordings. The test was repeated in the first, second, and third weeks of the treatment.. The mucociliary clearance was significantly slower in the acute bacterial rhinosinusitis group than in the control group. There was no significant difference between the basal mucociliary clearance and the 20th minute mucociliary clearance of the fluticasone propionate and 0.9% NaCl solution groups. The mean values of the basal and the 20 minute's mucociliary clearance of the oxymetazoline group were 24.72 +/- 6.16 and 15.5 +/- 7.45 minutes, respectively, which were statistically significant. The mean values of the basal and the 20th minute mucociliary clearance of the 3% NaCl solution groups were 19.45 +/- 9.35 and 15.45 +/- 8.20 minutes, respectively, which were also statistically significant. In the first group (without topical treatment), the basal mucociliary clearance became significantly shorter after the second week of treatment. In the first and second weeks of the treatment of the oxymetazoline group, the mucociliary clearance did not change significantly, but after the third week the mucociliary clearance was significantly shorter. In the 3% NaCl solution group, significant improvement began from the first week and continued through the third week. Comparing the basal and the third weeks' mucociliary clearance values among the groups, the oxymetazoline and 3% NaCl solution groups revealed more significant improvement than the other groups, but this improvement was not different from the improvement of group I. There was still a statistically significant difference in the mucociliary clearance of the post-treatment sinusitis groups from the control group.. The oxymetazoline and 3% NaCl solution groups seemed to be more effective in mucociliary clearance, but there was no significant difference in improvement among the groups. The improvement of acute bacterial rhinosinusitis takes more than 3 weeks, according to the mucociliary clearance values of the groups.

Adding salmeterol to low-dose fluticasone propionate (FP) produces greater improvements in pulmonary function and symptom control than increasing the dose of FP in patients who remain symptomatic with low-dose FP.. We sought to compare the rates and characteristics of asthma exacerbations in patients after adding salmeterol to low-dose FP with the rates and characteristics of exacerbations in patients receiving higher dose FP.. In 2 multicenter, double-blind studies, 925 patients 12 years of age and older receiving 88 microg twice daily FP randomly received either 42 microg of salmeterol and 88 microg of FP or an increased dose of FP (220 microg) twice daily for 24 weeks. Exacerbation rates and clinical measures of asthma worsening were assessed for all patients who experienced an asthma exacerbation.. The addition of salmeterol resulted in a significantly lower rate and number of exacerbations compared with higher dose FP. A total of 41 (8.8%) patients experienced 47 exacerbations with the addition of salmeterol compared with 63 (13.8%) patients with 75 exacerbations in the group receiving increased-dose FP (P =.017). Salmeterol plus low-dose FP was significantly more protective than increased-dose FP in preventing asthma exacerbations, as assessed by the time to first exacerbation (P <.05). In both groups clinical indicators of worsening asthma showed parallel changes before asthma exacerbation, and greater improvements were observed after exacerbation with salmeterol compared with higher dose FP.. Salmeterol plus low-dose FP was more effective than higher dose FP alone in reducing asthma exacerbations in patients with persistent asthma. The ability to detect deteriorating asthma and the severity of exacerbation was similar between groups.

Acute exacerbations of chronic bronchitis are common and the presenting symptoms vary, although it is not clear how this should influence management. From a health care perspective, an understanding of the speed of symptom resolution is of importance to determine the success of treatment or when a change is indicated because of treatment failure.. The response of 63 patients treated at home for exacerbations of chronic bronchitis was assessed using a patient directed diary card incorporating sputum characteristics and symptoms. Treatment was given according to the nature of the sputum at presentation; patients with purulent sputum received an antibiotic for 5 or 10 days (randomised, double blind) whereas patients with mucoid sputum received high dose inhaled steroid or placebo for 14 days (randomised, double blind).. The mean (SE) total diary card score at presentation was significantly higher in the purulent group than in the mucoid group (19.7 (0.9) v 16.3 (0.9); mean difference -3.4 (95% CI -6.1 to -0.7), p<0.05). In the purulent group sputum colour and volume improved rapidly and in both groups the mean (SE) total diary card score had improved by the fifth day of treatment to 13.0 (0.7) in the purulent group (mean difference -6.6 (95% CI -8.8 to -4.4), p<0.001) and 14.6 (0.8) in the mucoid group (mean difference -1.7 (95% CI -4.0 to 0.8), p<0.05), which was no longer significantly different from the stable state. Diary card scores did not differ significantly between patients who received antibiotics for 5 or 10 days in the purulent group or between patients who received inhaled fluticasone or placebo in the mucoid group.. Exacerbations of chronic bronchitis associated with purulent sputum have significantly worse symptoms at presentation than those with mucoid sputum. In both groups these symptoms resolve rapidly so that by the fifth day of treatment they are no different from the stable state. No significant effect was found on symptom resolution of antibiotic duration (5 v 10 days) in the purulent group or of inhaled fluticasone in the mucoid group, which resolved without antibiotics. Larger numbers may be required to demonstrate a statistically (if not clinically) significant difference.

It is not known whether intranasal corticosteroids are beneficial to treat acute rhinosinusitis in patients with a history of chronic or recurrent sinus symptoms.. To assess whether the addition of an intranasal corticosteroid to antibiotic therapy affects the speed and rate of recovery of such patients with acute rhinosinusitis.. A double-blind, randomized, placebo-controlled multicenter trial of 95 patients (median age, 39 years) with a history of recurrent sinusitis or chronic rhinitis and evidence of acute infection by sinus radiograph or nasal endoscopy, which was conducted from October 1998 through April 2000 at 22 sites (12 primary care and 10 otolaryngology).. Two puffs (total dose, 200 microgram) of fluticasone propionate (n = 47) or placebo nasal spray (n = 48) in each nostril once daily for 21 days; all received 2 puffs of xylometazoline hydrochloride in each nostril twice daily for 3 days and 250 mg of cefuroxime axetil twice daily for 10 days.. Time to clinical success (patient reported cured or much improved) during telephone follow-up at 10, 21, and 56 days.. A total of 88 patients (93%) completed follow-up. Patients recorded their symptoms, work assessment, and compliance during the 3-week treatment phase. Patients receiving fluticasone achieved a significantly higher rate of clinical success than patients receiving placebo (93.5% vs 73.9%; P =.009). Patients treated with fluticasone improved significantly more rapidly (median of 6.0 days to clinical success) vs patients in the placebo group (median of 9.5 days; P =.01).. The addition of fluticasone to xylometazoline and antimicrobial therapy with cefuroxime improves clinical success rates and accelerates recovery of patients with a history of chronic rhinitis or recurrent sinusitis who present for treatment of acute rhinosinusitis.

Acute otitis media (AOM) is the most common complication of a viral upper respiratory infection (URI) in children. The virus-induced host inflammatory response in the nasopharynx plays a key role in the pathogenesis of AOM. Suppression of this inflammatory process might prevent the development of AOM as a complication.. We sought to assess the effect of intranasally administered fluticasone propionate on prevention of AOM during a viral respiratory infection.. A total of 210 children (mean age, 2.1 years; range, 0.7-3.9 years) with normal middle ear status and URI of 48 hours' duration or less were randomly allocated to receive either fluticasone (100 microg twice daily) or placebo for 7 days. The specific viral cause of the infection was determined from nasopharyngeal aspirates obtained at the first visit. The children were re-examined at the end of the 7-day medication period.. In the fluticasone group AOM developed in 40 (38.1%) of 105 children compared with 29 (28.2%) of 103 children receiving placebo (P =.13). The viral cause of the respiratory infection was determined in 167 (86.1%) of 194 children from whom a nasopharyngeal aspirate was obtained. In children with rhinovirus infection, AOM developed significantly more often in the fluticasone group (45.7%) than in the placebo group (14.7%, P =.005).. Intranasally administered fluticasone does not prevent the development of AOM during URI but may increase the incidence of AOM during rhinovirus infection.

The aim of the present study was to investigate the efficacy and safety of nebulized fluticasone propionate (FP Nebules) compared with oral soluble prednisolone in children with an acute exacerbation of asthma. The study used an international, multi-centre, randomized, double-blind, parallel group design. Three hundred and twenty-one patients, aged 4-16 years old, who presented with an acute exacerbation of asthma, were randomly allocated to either nebulized FP (1 mg b.d.) or oral prednisolone (2 mg kg(-1) day(-1) for 4 days then 1 mg kg(-1) day(-1) for 3 days) for 7 days. Patients in the FP group showed a significantly greater increase in diary card morning peak expiratory flow (PEF) over 7 days compared with patients in the prednisolone group (difference = 9.51 min(-1), CI = 2.1, 16.8, P = 0.034). Similar increases for both treatments were shown for evening PEF. Clinic PEF improved with both treatments, but was significantly greater in patients taking FP after 7 days (difference = 11.41 min(-1), CI = 2.8, 20.0, P = 0.029). Both treatments reduced symptom scores to a similar extent. The two treatments were well tolerated, and there was no difference in the incidence of adverse events. The present study demonstrated that nebulized FP is at least as effective as oral prednisolone in the treatment of children presenting with an acute exacerbation of asthma.

To test whether the use of fluticasone dipropionate nasal spray after endoscopic ethmoidectomy for multiple polyps is associated with a high incidence of infection. DESIGN. Randomized control study comparing the incidence of infection with the use of beclomethasone dipropionate or fluticasone propionate nasal spray after functional endoscopic sphenoethmoidectomy. Patients were followed up for 6 to 12 months.. Sixty patients with recurrent bilateral nasal polyps underwent functional endoscopic sphenoethmoidectomy and were then randomly allocated into 2 groups of 30 patients each. One group received beclomethasone dipropionate spray (100 micrograms in each nostril every 12 hours), and the other group received fluticasone propionate spray (100 micrograms/d in each nostril).. In the fluticasone propionate group, 6 patients (20%) developed acute gram-positive pansinusitis requiring hospitalization and discontinuation of treatment.. The use of fluticasone dipropionate aqueous nasal spray for the postoperative control of recurrent nasal polyps seems to be associated with a high incidence of acute pansinusitis.

Oral corticosteroids used in short courses for acute asthma are regarded as safe, although the frequent use of these drugs may result in patients suffering from systemic side effects. It has become common practice for patients to increase their own inhaled corticosteroid intake when their asthma goes out of control, but it has never been established whether a high dose of inhaled corticosteroid can be as effective as a short course of oral corticosteroid in the treatment of acute exacerbations.. A multicentre, randomised, double blind, double dummy, parallel group study was undertaken to determine whether the introduction of a high dose of inhaled fluticasone propionate (2 mg daily) is as effective as a short reducing course of oral prednisolone (starting at 40 mg/day and reducing by 5 mg every other day) in the treatment of acute exacerbations of asthma not considered severe enough for admission to hospital but requiring treatment with oral corticosteroid.. Four hundred and thirteen adult asthmatic subjects who presented to their general practitioner with an acute exacerbation of asthma were recruited in 47 general practices in the United Kingdom. Treatment failures, defined as a reduction in peak expiratory flow (PEF) to below 60% of the patient's best/predicted value on two consecutive occasions or persistent symptoms with no improvement on three consecutive days, occurred in 23% of patients who received oral prednisolone and 27% who received inhaled fluticasone propionate (difference in percentage of treatment failures 4.3, 95% CI -4.1 to 12.8, p = 0.31). In each group 48% were classified as treatment successes, defined as a 10% or greater increase in percentage best/predicted morning PEF. Both treatments were equally well tolerated.. There is no evidence of a significant difference in efficacy between a reducing dose course of oral prednisolone and high dose inhaled fluticasone propionate in mild exacerbations of asthma which do not require admission to hospital.

Severe asthma and viral-induced asthma exacerbations represent a high unmet medical need as no therapy is currently available for these patients. HRV (human rhinovirus) is prominently associated with asthma exacerbations in humans. The aim of the present study was to establish a mouse model of severe asthma with additional rhinovirus infection to investigate the interplay between chronic allergic airway inflammation and acute respiratory viral infection. Balb/c mice were sensitized with HDM (house dust mite) extract (25 μg in 50 μl of saline) by i.n. (intranasal) delivery to the lung over 7 weeks. HRV1B (HRV serotype 1B) inoculation was performed i.n. on the last 3 days. Therapeutic treatment with FP (fluticasone propionate) was performed to assess steroid efficacy. Lung resistance was measured invasively to assess AHR (airway hyper-responsiveness). BAL (bronchoalveolar lavage) differential cell count, cytokines, lung histology and the proliferative and cytokine response of MLN (mediastinal lymph node) cells upon in vitro restimulation were analysed. Chronic HDM application induced a strong Th2-skewed eosinophilic airway inflammation and AHR, which was not exacerbated by superimposed HRV1B infection. Therapeutic steroid intervention in the chronic HDM model reduced BAL eosinophil cell counts, cytokine levels and AHR, while neutrophil numbers were unaffected. Steroid efficacy against inflammatory readouts was maintained during additional HRV1B infection. Animals with chronic allergic airway inflammation exhibited a diminished immune response towards superimposed HRV1B infection compared with HRV1B alone, as induction of the anti-viral and pro-inflammatory cytokines IFN (interferon)-α, IFN-γ and IL (interleukin)-12 were suppressed. Although superimposed HRV1B infection did not provoke asthma exacerbation in this severe model, a deficient anti-viral immune response to HRV1B was present under chronic allergic airway inflammatory conditions. Thus, this model is able to reflect some aspects of the complex interplay of respiratory virus infection in chronic allergic asthma.

Pre-clinical evaluation of asthma therapies requires animal models of chronic airways inflammation, airway hyperresponsiveness (AHR) and lung remodelling that accurately predict drug effectiveness in human asthma. However, most animal models focus on acute allergen challenges where chronic inflammation and airway remodelling are absent. Chronic allergen challenge models have been developed in mice but few studies use guinea-pigs which may be more relevant to humans. We tested the hypothesis that a chronic rather than acute pulmonary inflammation model would best predict clinical outcome for asthma treatments. Guinea-pigs sensitized with ovalbumin (OVA) received single (acute) or nine OVA inhalation challenges at 48 h intervals (chronic). Airways function was recorded as specific airways conductance (sG(aw)) in conscious animals for 12 h after OVA challenge. AHR to inhaled histamine, inflammatory cell influx and lung histology were determined 24 h after the single or 9th OVA exposure. The inhaled corticosteroid, fluticasone propionate (FP), the phosphodiesterase 4 inhibitor, roflumilast, and the inducible nitric oxide synthase (iNOS) inhibitor, GW274150, orally, were administered 24 and 0.5 h before and 6 h after the single or final chronic OVA exposure. Both models displayed early (EAR) and late (LAR) asthmatic responses to OVA challenge, as falls in sG(aw), AHR, as increased histamine-induced bronchoconstriction, and inflammatory cell influx. Tissue remodelling, seen as increased collagen and goblet cell hyperplasia, occurred after multiple OVA challenge. Treatment with FP and roflumilast inhibited the LAR, cell influx and AHR in both models, and the remodelling in the chronic model. GW274150 also inhibited the LAR, AHR and eosinophil influx in the acute model, but not, together with the remodelling, in the chronic model. In the clinical setting, inhaled corticosteroids and phosphodiesterase 4 inhibitors are relatively effective against most features of asthma whereas the iNOS inhibitor GW274150 was ineffective. Thus, while there remain certain differences between our data and clinical effectiveness of these antiasthma drugs, a chronic pulmonary inflammation guinea-pig model does appear to be a better pre-clinical predictor of potential asthma therapeutics than an acute model.

Central airway nitric oxide flux (J'(awNO)) and peripheral airway/alveolar nitric oxide concentration (C(ANO)) during asthma exacerbation has not been investigated after correction for axial NO back-diffusion.. After measuring exhaled NO (fraction of exhaled nitric oxide (F(E)NO); ppb) at 50, 100, 150 and 200 ml/s, J'(awNO) (nl/s) and C(ANO) (ppb) were calculated using the two-compartment model and corrected for axial NO back-diffusion. Fifteen (8 males), non-smoking, patients with moderate-to-severe treated (inhaled corticosteroid (ICS) and inhaled long-acting beta(2)-agonist (LABA)) asthma, age 57+/-13 years (mean+/-SD), were studied at baseline, during exacerbation prior to oral corticosteroid, and during recovery after an 8 day tapering prednisone course. Based on earlier asthma studies without correction, it was hypothesised that with correction for NO axial back-diffusion, the incidence of abnormal J'(awNO) and C(ANO) at baseline and after exacerbation would be > or = 30% in 15 patients with asthma with 80% power.. At baseline when clinically stable, after 180 microg of albuterol, forced expiratory volume in 1 s (FEV(1); litres) was 78+/-26% predicted (p=0.009) with increased F(E)NO at 50 ml/s (p=0.01) and J'(awNO) (p=0.02), but C(ANO) was normal compared with the controls. During exacerbation FEV(1) (litres) was 57+/-20% predicted (p=0.02), with increased F(E)NO at 50 ml/s (p=0.01) and J'(awNO) (p=0.004), but C(ANO) was normal. Recovery results were similar to baseline. Two of 15 patients with asthma always had normal exhaled NO gas exchange.. The central airways were the major site of abnormal NO flux in 13 of 15 patients with moderate-severe asthma when stable and during exacerbation and could be easily detected with abnormal F(E)NO at 50 ml/s. C(ANO) was normal.

Inhaled corticosteroids (ICSs) are often prescribed as the first line therapy for pulmonary diseases such as asthma. The biggest concern of using steroid therapy is the systemic side effects at high dose. To reduce the side effects, the pharmaceutical industry has been putting effort to generate new drugs with maximized topical efficacy. One of the key challenges is to differentiate efficacy from local versus systemic contribution in preclinical animal models. Fluticasone with various formulations was used as a model compound to explore the possibilities to demonstrate lung targeted efficacy by intratracheally instillation in the lipopolysaccharide induced inflammation rat model. Fluticasone formulations contained various surfactant concentrations and particle sizes to achieve lung retention and lower systemic exposure. Neutrophil infiltration in broncoalveolar lavage fluid and cytokine production in whole blood were measured to assess pulmonary efficacy versus systemic efficacy. PK/PD characterization of fluticasone with various formulations in the rat inflammation model provided an integrated approach in preclinical to evaluate lung targeted efficacy for ICS. Our study concluded that the combination of the rat LPS model and fluticasone is not suitable to use for establishing potency and dose requirement for new drug candidate designed for topical only efficacy.

Monocyte chemotactic protein 1 (MCP-1) plays an important role in various immune and allergic disorders since it is a potent chemo-attractant for inflammatory cells, such as eosinophils, memory T cells, and monocytes.. To investigate serum MCP-1 during asymptomatic state and acute attacks of bronchial asthma.. In this longitudinal cohort design study, sequential serum levels of MCP-1 were measured by a sandwich enzyme-linked immunosorbent assay (ELISA). Twenty-four asthma patients' MCP-1 levels were examined at 5 time points: during the asymptomatic phase, in an acute wheezing episode, and at 1 week, 1 month, and 2 months after acute asthma attack. Fifteen children without asthma were enrolled as control.. During the asymptomatic phase of asthma, serum MCP-1 levels were significantly higher than that of normal controls (329.57 +/- 99.20 pg/ml vs. 213.63 +/- 77.29 pg/ml, p = 0.001). In comparison with the asymptomatic phase, the serum MCP-1 levels during the acute asthma attack were significantly higher (682.88 +/- 88.45 pg/ml vs. 329.57 +/- 99.20 pg/ml, p < 0.001). After treatment of acute asthma exacerbation, all of the serum MCP-1 levels declined within 1 week, but were still higher than control 2 months later.. In asthma patients, the consistently elevated serum levels of MCP-1 suggest its role in the pathogenesis of bronchial asthma - not only in the chronic inflammatory processes, but also in acute asthma attack exacerbation. These findings suggest a possible role for MCP-1 in the pathogenesis of asthma and a potential role for its use in anti-asthma treatment in the future.

International guidelines recommend prescription of inhaled corticosteroids to improve asthma control. Chronic secondary adrenal suppression due to inhaled corticosteroids has been described. We report a case of acute adrenal suppression due to drug interaction between Fluticasone and antiretroviral therapy in a HIV patient. Seeing an increased prevalence of hyperresponsiveness among HIV-infected men, we conclude that coprescription of Fluticasone and highly active antiretroviral therapy must be carefully controlled.

Four cases of asthma (one adult, three children) developing acute adrenal crisis after introduction of high-dose inhaled fluticasone proprionate are presented. The three children, aged 7-9 yrs, had been prescribed inhaled fluticasone, dosage 500-2,000 microg x day(-1) and duration 5 months-5 yrs. All presented with convulsions due to hypoglycaemia (blood glucose 1.3-1.8 mM). The fourth case was a male of 33 yrs with difficult-to-control asthma and had been taking fluticasone propionate 1,000-2,000 microg x day(-1) for 3 yrs. He presented with fatigue, lethargy, nausea and postural hypotension. Acute adrenal crisis in each case was confirmed by investigations which included measurement of acute phase cortisol levels, short and long Synacthen stimulation tests and glucagon stimulation tests. Other cases of hypthoalamic-pituitary-adrenal axis suppression were excluded.
