RESUMO

OBJECTIVE: Seasonal allergic rhinitis (SAR) is a common disease of childhood and is characterized by type 2 inflammation, bothersome symptoms, and impaired quality of life (QoL). Intranasal corticosteroids are effective medications in managing SAR. In addition, mometasone furoate nasal spray (MFNS) is a well-known therapeutic option. However, the literature provided no data about the effects of MFNS in European children with SAR. Thus, this study addressed this unmet requirement. METHODS: MFNS was compared to isotonic saline. Both treatments were prescribed: one drop of spray per nostril, twice a day, for 3 weeks. Nasal cytology, total symptom score (TSS), visual analogic scale concerning the parental perception of severity of symptoms, and the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) were assessed at baseline, after 7 and 21 days, and 1 month after discontinuation. RESULTS: MFNS significantly reduced eosinophil and mast cell counts, improved QoL, and relieved symptoms, as assessed by doctors and perceived by parents. These effects persisted over time, even after discontinuation. Both treatments were safe and well-tolerated. CONCLUSIONS: The present study documented that a 3-week MFNS treatment was able to significantly dampen type 2 inflammation, improve QoL, and reduce severity of symptoms in Italian children with SAR, and was safe.

RESUMO

BACKGROUND: Treatment with corticosteroids is recommended for Duchenne muscular dystrophy (DMD) patients to slow the progression of weakness. However, chronic corticosteroid treatment causes significant morbidities. Vamorolone is a first-in-class anti-inflammatory investigational drug that has shown evidence of efficacy in DMD after 24 weeks of treatment at 2.0 or 6.0 mg/kg/day. Here, open-label efficacy and safety experience of vamorolone was evaluated over a period of 18 months in trial participants with DMD. METHODS AND FINDINGS: A multicenter, open-label, 24-week trial (VBP15-003) with a 24-month long-term extension (VBP15-LTE) was conducted by the Cooperative International Neuromuscular Research Group (CINRG) and evaluated drug-related effects of vamorolone on motor outcomes and corticosteroid-associated safety concerns. The study was carried out in Canada, US, UK, Australia, Sweden, and Israel, from 2016 to 2019. This report covers the initial 24-week trial and the first 12 months of the VBP15-LTE trial (total treatment period 18 months). DMD trial participants (males, 4 to <7 years at entry) treated with 2.0 or 6.0 mg/kg/day vamorolone for the full 18-month period (n = 23) showed clinical improvement of all motor outcomes from baseline to month 18 (time to stand velocity, p = 0.012 [95% CI 0.010, 0.068 event/second]; run/walk 10 meters velocity, p < 0.001 [95% CI 0.220, 0.491 meters/second]; climb 4 stairs velocity, p = 0.001 [95% CI 0.034, 0.105 event/second]; 6-minute walk test, p = 0.001 [95% CI 31.14, 93.38 meters]; North Star Ambulatory Assessment, p < 0.001 [95% CI 2.702, 6.662 points]). Outcomes in vamorolone-treated DMD patients (n = 46) were compared to group-matched participants in the CINRG Duchenne Natural History Study (corticosteroid-naïve, n = 19; corticosteroid-treated, n = 68) over a similar 18-month period. Time to stand was not significantly different between vamorolone-treated and corticosteroid-naïve participants (p = 0.088; least squares [LS] mean 0.042 [95% CI -0.007, 0.091]), but vamorolone-treated participants showed significant improvement compared to group-matched corticosteroid-naïve participants for run/walk 10 meters velocity (p = 0.003; LS mean 0.286 [95% CI 0.104, 0.469]) and climb 4 stairs velocity (p = 0.027; LS mean 0.059 [95% CI 0.007, 0.111]). The vamorolone-related improvements were similar in magnitude to corticosteroid-related improvements. Corticosteroid-treated participants showed stunting of growth, whereas vamorolone-treated trial participants did not (p < 0.001; LS mean 15.86 [95% CI 8.51, 23.22]). Physician-reported incidences of adverse events (AEs) for Cushingoid appearance, hirsutism, weight gain, and behavior change were less for vamorolone than published incidences for prednisone and deflazacort. Key limitations to the study were the open-label design, and use of external comparators. CONCLUSIONS: We observed that vamorolone treatment was associated with improvements in some motor outcomes as compared with corticosteroid-naïve individuals over an 18-month treatment period. We found that fewer physician-reported AEs occurred with vamorolone than have been reported for treatment with prednisone and deflazacort, and that vamorolone treatment did not cause the stunting of growth seen with these corticosteroids. This Phase IIa study provides Class III evidence to support benefit of motor function in young boys with DMD treated with vamorolone 2.0 to 6.0 mg/kg/day, with a favorable safety profile. A Phase III RCT is underway to further investigate safety and efficacy. TRIAL REGISTRATION: Clinical trials were registered at www.clinicaltrials.gov, and the links to each trial are as follows (as provided in manuscript text): VBP15-002 [NCT02760264] VBP15-003 [NCT02760277] VBP15-LTE [NCT03038399].

RESUMO

OBJECTIVE AND DESIGN: The objective of this study was to assess the effect of vamorolone, a first-in-class dissociative steroidal compound, to inhibit inflammation when administered after disease onset in the murine collagen antibody-induced arthritis model of arthritis. ANIMALS: 84 DBA1/J mice were used in this study (n = 12 per treatment group). TREATMENT: Vamorolone or prednisolone was administered orally after disease onset for a duration of 7 days. METHODS: Disease score and bone erosion were assessed using previously described scoring systems. Cytokines were measured in joints via immunoassay, and joint cathepsin B activity (marker of inflammation) was assessed using optical imaging of joints on live mice. RESULTS: We found that vamorolone treatment led to a reduction of several disease parameters including disease score, joint inflammation, and the presence of pro-inflammatory mediators to a degree similar of that observed with prednisolone treatment. More importantly, histopathological analysis of affected joints showed that vamorolone treatment significantly reduced the degree of bone erosion while this bone-sparing property was not observed with prednisolone treatment at any of the tested doses. CONCLUSIONS: While many intervention regimens in other studies are administered prior to disease onset in animal models, the current study involves delivery of the potential therapeutic after disease onset. Based on the findings, vamorolone may offer an efficacious, yet safer alternative to conventional steroidal compounds in the treatment of rheumatoid arthritis and other inflammatory diseases.

RESUMO

Mutations of the DYSF gene leading to reduced dysferlin protein level causes limb girdle muscular dystrophy type 2B (LGMD2B). Dysferlin facilitates sarcolemmal membrane repair in healthy myofibers, thus its deficit compromises myofiber repair and leads to chronic muscle inflammation. An experimental therapeutic approach for LGMD2B is to protect damage or improve repair of myofiber sarcolemma. Here, we compared the effects of prednisolone and vamorolone (a dissociative steroid; VBP15) on dysferlin-deficient myofiber repair. Vamorolone, but not prednisolone, stabilized dysferlin-deficient muscle cell membrane and improved repair of dysferlin-deficient mouse (B6A/J) myofibers injured by focal sarcolemmal damage, eccentric contraction-induced injury or injury due to spontaneous in vivo activity. Vamorolone decreased sarcolemmal lipid mobility, increased muscle strength, and decreased late-stage myofiber loss due to adipogenic infiltration. In contrast, the conventional glucocorticoid prednisolone failed to stabilize dysferlin deficient muscle cell membrane or improve repair of dysferlinopathic patient myoblasts and mouse myofibers. Instead, prednisolone treatment increased muscle weakness and myofiber atrophy in B6A/J mice-findings that correlate with reports of prednisolone worsening symptoms of LGMD2B patients. Our findings showing improved cellular and pre-clinical efficacy of vamorolone compared to prednisolone and better safety profile of vamorolone indicates the suitability of vamorolone for clinical trials in LGMD2B.

RESUMO

We report a first-in-patient study of vamorolone, a first-in-class dissociative steroidal anti-inflammatory drug, in Duchenne muscular dystrophy. This 2-week, open-label Phase IIa multiple ascending dose study (0.25, 0.75, 2.0, and 6.0 mg/kg/day) enrolled 48 boys with Duchenne muscular dystrophy (4 to <7 years), with outcomes including clinical safety, pharmacokinetics and pharmacodynamic biomarkers. The study design included pharmacodynamic biomarkers in three contexts of use: 1. Secondary outcomes for pharmacodynamic safety (insulin resistance, adrenal suppression, bone turnover); 2. Exploratory outcomes for drug mechanism of action; 3. Exploratory outcomes for expanded pharmacodynamic safety. Vamorolone was safe and well-tolerated through the highest dose tested (6.0 mg/kg/day) and pharmacokinetics of vamorolone were similar to prednisolone. Using pharmacodynamic biomarkers, the study demonstrated improved safety of vamorolone versus glucocorticoids as shown by reduction of insulin resistance, beneficial changes in bone turnover (loss of increased bone resorption and decreased bone formation only at the highest dose level), and a reduction in adrenal suppression. Exploratory biomarkers of pharmacodynamic efficacy showed an anti-inflammatory mechanism of action and a beneficial effect on plasma membrane stability, as demonstrated by a dose-responsive decrease in serum creatine kinase activity. With an array of pre-selected biomarkers in multiple contexts of use, we demonstrate the development of the first dissociative steroid that preserves anti-inflammatory efficacy and decreases steroid-associated safety concerns. Ongoing extension studies offer the potential to bridge exploratory efficacy biomarkers to clinical outcomes.

RESUMO

OBJECTIVE AND DESIGN: The goal of this study was to assess the capacity of VBP15, a dissociative steroidal compound, to reduce pro-inflammatory cytokine expression in vitro, to reduce symptoms of colitis in the trinitrobenzene sulfonic acid-induced murine model, and to assess the effect of VBP15 on growth stunting in juvenile mice. MATERIALS: In vitro studies were performed in primary human intestinal epithelial cells. Colitis was induced in mice by administering trinitrobenzene sulfonic acid. Growth stunting studies were performed in wild type outbred mice. TREATMENT: Cells were treated with VBP15 or prednisolone (10 µM) for 24 h. Mice were subjected to 3 days of VBP15 (30 mg/kg) or prednisolone (30 mg/kg) in the colitis study. In the growth stunting study, mice were subjected to VBP15 (10, 30, 45 mg/kg) or prednisolone (10 mg/kg) for 5 weeks. METHODS: Cytokines were measured by PCR and via Luminex. Colitis symptoms were evaluated by assessing weight loss, intestinal blood, and stool consistency. Growth stunting was assessed using an electronic caliper. RESULTS: VBP15 significantly reduced the in vitro production of CCL5 (p < 0.001) IL-6 (p < 0.001), IL-8 (p < 0.05) and reduced colitis symptoms (p < 0.05). VBP15 caused less growth stunting than prednisolone (p < 0.001) in juvenile mice. CONCLUSION: VBP15 may reduce symptoms of IBD, while decreasing or avoiding detrimental side effects.

RESUMO

BACKGROUND: Chronic sinonasal disease is common in asthmatic patients and associated with poor asthma control; however, there are no long-term trials addressing whether chronic treatment of sinonasal disease improves asthma control. OBJECTIVE: We sought to determine whether treatment of chronic sinonasal disease with nasal corticosteroids improves asthma control, as measured by the Childhood Asthma Control Test and Asthma Control Test in children and adults, respectively. METHODS: A 24-week multicenter, randomized, placebo-controlled, double-blind trial of placebo versus nasal mometasone in adults and children with inadequately controlled asthma was performed. Treatments were randomly assigned, with concealment of allocation. RESULTS: Two hundred thirty-seven adults and 151 children were randomized to nasal mometasone versus placebo, and 319 participants completed the study. There was no difference in the Childhood Asthma Control Test score (difference in change with mometasone - change with placebo [ΔM - ΔP], -0.38; 95% CI, -2.19 to 1.44; P = .68; age 6-11 years) or the Asthma Control Test score (ΔM - ΔP, 0.51; 95% CI, -0.46 to 1.48; P = .30; age ≥12 years) in those assigned to mometasone versus placebo. In children and adolescents (age 6-17 years) there was no difference in asthma or sinus symptoms but a decrease in episodes of poorly controlled asthma defined by a decrease in peak flow. In adults there was a small difference in asthma symptoms measured by using the Asthma Symptom Utility Index (ΔM - ΔP, 0.06; 95% CI, 0.01 to 0.11; P < .01) and in nasal symptoms (sinus symptom score ΔM - ΔP, -3.82; 95% CI, -7.19 to -0.45; P = .03) but no difference in asthma quality of life, lung function, or episodes of poorly controlled asthma in adults assigned to mometasone versus placebo. CONCLUSIONS: Treatment of chronic sinonasal disease with nasal corticosteroids for 24 weeks does not improve asthma control. Treatment of sinonasal disease in asthmatic patients should be determined by the need to treat sinonasal disease rather than to improve asthma control.

RESUMO

Multiple sclerosis is a chronic disease of the central nervous system characterized by an autoimmune inflammatory reaction that leads to axonal demyelination and tissue damage. Glucocorticoids, such as prednisolone, are effective in the treatment of multiple sclerosis in large part due to their ability to inhibit pro-inflammatory pathways (e.g., NFκB). However, despite their effectiveness, long-term treatment is limited by adverse side effects. VBP15 is a recently described compound synthesized based on the lazeroid steroidal backbone that shows activity in acute and chronic inflammatory conditions, yet displays a much-reduced side effect profile compared to traditional glucocorticoids. The purpose of this study was to determine the effectiveness of VBP15 in inhibiting inflammation and disease progression in experimental autoimmune encephalomyelitis (EAE), a widely used mouse model of multiple sclerosis. Our data show that VBP15 is effective at reducing both disease onset and severity. In parallel studies, we observed that VBP15 was able to inhibit the production of NFκB-regulated pro-inflammatory transcripts in human macrophages. Furthermore, treatment with prednisolone-but not VBP15-increased expression of genes associated with bone loss and muscle atrophy, suggesting lack of side effects of VBP15. These findings suggest that VBP15 may represent a potentially safer alternative to traditional glucocorticoids in the treatment of multiple sclerosis and other inflammatory diseases.

RESUMO

BACKGROUND: Topical ear medications, often containing a glucocorticoid, are used to treat the clinical signs of atopic otitis in dogs. Studies have looked at the inhibitory effect of topical glucocorticoids on intradermal testing (IDT), but only one previously published study evaluated the influence of an otic glucocorticoid on the results of IDT in dogs. HYPOTHESIS/OBJECTIVES: To assess what influence the absorption of the diester glucocorticoid mometasone furoate (MF) had on intradermal test immediate reactions, to determine an appropriate withdrawal time prior to IDT. METHODS: Twenty atopic dogs were enrolled. On day 0, histamine, rabbit anticanine IgE antiserum and saline were injected intradermally. After 20 min, a global wheal score (GWS) was determined. The otic medication, MF, was applied once daily for 14 days. Intradermal injections were then repeated and, if the GWS was within 25% of pretreatment values, the study was completed for this dog. If the GWS had decreased by ≥25% from the baseline value, the otic medication was withdrawn, and the GWS was repeated every 7 days until its value was within 25% of the original GWS. RESULTS: Three of the 20 dogs completed the study on day 14, while 17 of 20 dogs ended it on day 21, 7 days after withdrawal of the drug, MF. CONCLUSIONS AND CLINICAL IMPORTANCE: Results from this study show that a withdrawal period of ≤7 days is possible before performing IDT in atopic dogs with active otitis externa treated with ≤14 days of MF.

RESUMO

BACKGROUND: Guidelines identify a 3-month topical application of an ultra-potent corticosteroid ointment as the mainstay of medical treatment for vulvar lichen sclerosus (VLS). However, there are no trials providing evidence that any specific corticosteroid is superior to another. OBJECTIVE: To assess the effectiveness and safety of a 12-week application of mometasone furoate (MMF) 0.1% ointment, with a tapering regimen, in achieving control of VLS signs and symptoms and to detect potential risk factors for VLS non-response. METHODS: 147 patients affected with VLS were enrolled in a 12-week active treatment phase (ATP) with topical 0.1% MMF. The primary efficacy endpoint was the rate of patients achieving clinical response, as defined by protocol parameters. The secondary efficacy endpoint was to assess the changes of mean VLS-related symptoms after the 12-week ATP compared with baseline. RESULTS: By the end of the ATP, 113 patients (80.7%) experienced a treatment response, whereas 27 women (19.3%) were judged as non-responders. Mean symptom scores decreased significantly in the study patients, regardless of their clinical response at the end of the ATP. Among all the epidemiological and clinical data considered, only the absence of previous medical therapies was found to be related to a significantly higher risk of non-response to treatment. CONCLUSIONS: Application of 0.1% MMF ointment for 12 weeks on a tapering regimen was found to be an effective and safe therapy option in the ATP of VLS and could represent an alternative first-line treatment to an ultra-potent molecule.

RESUMO

Lichen striatus is a localized, eczematous disorder distributed along the lines of Blaschko, primarily affecting children. In the literature, lesions have been described as having an active phase of inflamed lesions for 6 to 12 months followed by flattening and persistent pigmentary alteration. We describe two girls who had prolonged active-phase lesions for 2.5 and 3.5 years, respectively. Practitioners should be aware that lesions of lichen striatus may have a prolonged active phase.

RESUMO

Ataxia-telangiectasia (AT) is a rare autosomal recessive disorder characterized by faulty DNA damage repair. The disease affects multiple systems and is noted to be particularly difficult to diagnose in children because of the wide spectrum of clinical presentations. We present an unusual case of a child in whom the primary cutaneous manifestation of AT was noninfectious cutaneous caseating granulomas. A 3-year-old girl presented to the emergency department with ataxia, poor growth, and multiple ulcerated plaques on both upper extremities that had been present for 2 years. She had two prolonged hospitalizations and underwent extensive examination to identify an etiology for the skin lesions. She was diagnosed with AT after immunology examinaton and genetic testing. Outpatient intravenous immunoglobulin (IVIG) therapy was initiated and she was prescribed twice-daily mometasone 0.01% ointment under occlusion. After 6 weeks on this regimen her lesions had completely healed. Twenty-two cases of AT have been reported in which patients presented with cutaneous granulomas. This report demonstrates the first reported case in which the granulomatous skin lesions of AT healed after aggressive application of topical steroids with concurrent IVIG therapy, without oral steroids. A brief review of cutaneous granulomas in the setting of immunodeficiency is also presented.

RESUMO

PURPOSE: To assess the efficacy of nasal expiratory sound analysis in determining the degree of nasal obstruction. MATERIALS AND METHODS: We have analyzed and recorded the expiratory nasal sounds in 18 healthy controls and in 30 patients with inferior turbinate hypertrophy before and after the administration of nasal corticosteroid treatment. Analysis consisted of the time-expanded waveform, spectral analysis with time-averaged fast Fourier transform and waveform analysis of nasal sound. RESULTS: Before treatment, an increase in sound intensity at high frequency was observed in the sound analyses of the patients, whereas after treatment, a decrease in sound intensity at high frequency was noted in the sound analyses of the patients. The differences between the patients and the control group were statistically significant. Data obtained with the Odiosoft-Rhino method were correlated with symptom scores and endoscopic examination. CONCLUSION: Expiratory nasal sound is a practical and objective tool, which can be reliably used not only for the assessment of the degree of nasal blockage but also for the comparison of different treatment alternatives.

RESUMO

Fixed drug eruption (FDE) is a rare form of drug allergies that recur at the same cutaneous or mucosal site in every usage of drug. Single or multiple round, sharply demarcated and dusky red plaques appear soon after drug exposure. Ursodeoxycholic acid (UDCA: 3α,7ß-dihydroxy-5ß-cholanic acid) is used for the treatment of cholestatic liver diseases. Some side effects may be observed, such as diarrhea, dyspepsia, pruritus and headaches. We encountered only three cases of lichenoid reaction regarding the use of UDCA among previous studies. In this article, we reported a generalized FDE case related to UDCA intake in a 59-year-old male patient with cholestasis for the first time in the literature.

RESUMO

Dermatological inflammatory diseases often affect the scalp and the eyebrows. Common dosage forms available on the market for those situations are lotions; however, the presence of hair limits their use. Gels, for their consistency and adhesiveness, are a suitable alternative to the lotions in these situations. The aim of this study was to develop a new stable gel containing mometasone furoate (MF), with anti-inflammatory activity and a controlled delivery, to improve topical treatment of scalp dermatitis. Pharmaceutical development, physical and chemical characterization, stability, in vitro release and permeation studies and in vivo anti-inflammatory activity were performed. The gel presented an acidic pH and an apparent viscosity of 35 Pa.s. The microbiological analysis showed that the results were within the established specification limits. The release and the permeation profiles suggest that the drug is mainly retained in the upper skin layers. MF gel was tested in an animal model of cutaneous inflammation and presented similar anti-inflammatory activity compared to a commercially available MF dosage form. The gel was chemically, physically and microbiologically stable. The results suggest that the developed hydrogel formulation containing MF can be of actual value for improving the clinical effectiveness in the treatment of scalp dermatitis.

RESUMO

AIMS: The aim of this study was to assess protein and mRNA expression of epithelial membrane protein 1 (EMP1) in the nasal mucosa of patients with nasal polyps (NP), and to determine what changes occur in response to glucocorticosteroid (GC) treatment. METHODS AND RESULTS: NP tissue was obtained from 55 patients, 18 of whom were treated with nasal GCs (i.e. these 18 patients had NP biopsies taken before and after treatment). Biopsies of inferior turbinate mucosa from 30 healthy subjects were used as controls. Quantitative PCR and immunohistochemistry were performed to determine the expression levels of EMP1. EMP1 mRNA expression was significantly lower (2.77-fold) in tissues from NP patients before GC treatment when compared to controls, but was increased in these patients after GC treatment. EMP1 staining in nasal epithelium co-localized with both basal (p63(+)) and differentiated (CK18(+)) epithelial cells. Their immunoreactivity was significantly greater in controls than NP patients. EMP1 mRNA levels were lower in the epithelium with severe hyperplasia (1.79-fold) or with metaplasia (1.85-fold) as compared to those with mild to moderate hyperplasia or non-metaplastic epithelium, respectively. Positive correlations between EMP1 and other epithelial cell-related gene (e.g. JUN, PTGS2, AREG etc.) mRNAs were observed. CONCLUSIONS: EMP1 could be a biomarker for aberrant epithelial remodelling and metaplasia in chronic inflammatory upper airway mucosa (e.g. NP).

RESUMO

Chlorine gas is a widely used industrial compound that is highly toxic by inhalation and is considered a chemical threat agent. Inhalation of high levels of chlorine results in acute lung injury characterized by pneumonitis, pulmonary edema, and decrements in lung function. Because inflammatory processes can promote damage in the injured lung, anti-inflammatory therapy may be of potential benefit for treating chemical-induced acute lung injury. We previously developed a chlorine inhalation model in which mice develop epithelial injury, neutrophilic inflammation, pulmonary edema, and impaired pulmonary function. This model was used to evaluate nine corticosteroids for the ability to inhibit chlorine-induced neutrophilic inflammation. Two of the most potent corticosteroids in this assay, mometasone and budesonide, were investigated further. Mometasone or budesonide administered intraperitoneally 1h after chlorine inhalation caused a dose-dependent inhibition of neutrophil influx in lung tissue sections and in the number of neutrophils in lung lavage fluid. Budesonide, but not mometasone, reduced the levels of the neutrophil attractant CXCL1 in lavage fluid 6h after exposure. Mometasone or budesonide also significantly inhibited pulmonary edema assessed 1 day after chlorine exposure. Chlorine inhalation resulted in airway hyperreactivity to inhaled methacholine, but neither mometasone nor budesonide significantly affected this parameter. The results suggest that mometasone and budesonide may represent potential treatments for chemical-induced lung injury.

RESUMO

BACKGROUND: Mometasone furoate nasal spray (MFNS) improves nasal symptoms and reduces polyp size in adults with nasal polyposis. This 4-month, multinational, randomized, double-blind study was conducted to assess the safety of MFNS in pediatric subjects aged 6-17 yr. METHODS: Subjects aged 6-11 yr with bilateral nasal polyps received MFNS 100 µg once or twice daily or placebo; those aged 12-17 yr received MFNS 200 µg once or twice daily or placebo. End-points included change in 24-h urinary free cortisol (primary), change in 24-h urinary free cortisol corrected for creatinine (key secondary), and adverse events. Efficacy parameters included polyp size, nasal symptoms, and investigator-evaluated therapeutic response, although the study was not powered for statistical analysis of efficacy. RESULTS: Least squares baseline mean urinary free cortisol level (nmol/24 h) for both age groups combined (N = 127) was 49.5 in the MFNS once-daily group, 39.6 in the MFNS twice-daily group, and 49.8 in the placebo group. Change in 24-h urinary free cortisol did not significantly differ among MFNS- and placebo-treated subjects. Least squares mean 24-h urinary free cortisol levels corrected for creatinine also showed no significant differences among MFNS- and placebo-treated subjects. No safety issues emerged. CONCLUSIONS: Results of this study confirm the safety profile of MFNS in pediatric patients with bilateral nasal polyps over 4 months, even at double the recommended pediatric dosage for allergic rhinitis.

RESUMO

This study aimed at observing the efficacy of mometasone fuorate monohydrate nasal spray on obstructive adenoids in children and identifying the characteristics of responders using a pilot study including children aged 2-11 years, with evidence of more than 50 % obstruction. Allergic rhinitis and nasal obstruction were evaluated on baseline (V0), 6- (V1), and 12-week (V2) visits. Degree of obstruction was evaluated by nasopharyngoscopy at V0 and V2. Subjects received 100 µg mometasone fuorate daily. Results were compared with those of a matching control group. Nineteen children (8 females, 11 males; 2.25-8.50 years old, mean 4.24 years, median 4.00 years) completed treatment and follow-up adequately. There was 58 % reduction in a clinical score assessing the severity of adenoidal obstruction (P < 0.05), 56 % reduction in severity of obstructive symptom (P < 0.05), and 75 % reduction in allergic rhinitis score (P < 0.05) between V0 and V1. No further significant improvement was noticed between V1 and V2. The degree of obstruction dropped from 85 to 61 % as noted on endoscopy (P < 0.05). None in the control group showed spontaneous decrease or resolution of the symptoms. Age of patients, allergic rhinitis score, and severity of the clinical score had no impact on the response parameters. No side effects were observed. Mometasone furoate monohydrate nasal spray appears to be effective in treating children with obstructive adenoids. The effect seems to be independent of the presence of mild intermittent allergic rhinitis, the age of patient, or the severity of symptoms.

RESUMO

Aim of this work is to find out whether the symptoms attributable to adenoid hypertrophy in adolescents may be treated with intranasal mometasone furoate (MF) application. To learn if adenoid hypertrophy in adolescents may decrease in size with intranasal MF. A prospective, double blind, randomized, cross-over study was conducted in 28 subjects (12-18 years) with adenoidal hypertrophy. Subjects used intranasal MF or placebo for a duration of 6 weeks with a wash out period of 3 weeks. Subjective symptoms and adenoid size were evaluated. At the initiation of the study, there was no significant difference between the mean symptom scores for any of the sinonasal symptoms between the two treatment groups. There was significant improvement in total subjective symptoms (nasal blockage, rhinorrhea, cough, snoring and disruption of quality of life scores) with MF compared with placebo. Analysis of the symptoms separately showed a significant positive effect of MF on all symptoms except for rhinorrhea. Nasal endoscopic evaluation failed to demonstrate any difference in the reduction of the adenoid size between the two groups. MF has significant advantage over placebo for the symptoms attributable to adenoid hypertrophy in adolescents.
