A pediatric case of dupilumab-induced pustular psoriasis.

Dupilumab is a novel treatment agent for moderate to severe atopic dermatitis (AD) with few adverse effects. Drug-induced psoriasiform lesions are rare.We report a 4-year-old boy with AD who developed pustular psoriasis during treatment with dupilumab.Pustular psoriasis appeared within 1 week of treatment and worsened in the second week. After stopping dupilumab administration, topical corticosteroids (desonide and mometasone furoate creams) and oral desloratadine without relief. Pustular psoriasis was confirmed by pathological examination, and thiamphenicol was administered. After 2 weeks of treatment, the lesions nearly resolved without recurrence in 1-year follow-up.Dupilumab-induced pustular psoriasis is rare in children.

Low drug load, high retention mometasone furoate cream with polyglyceryl - 3 oleate as a chemical enhancer: Formulation development, in vivo and in vitro evaluation and molecular mechanisms.

The study aimed to create a low loading, high retention, easier to apply O/W mometasone furoate (MF) cream using a chemical enhancer (CE) approach to provide more options for patients with atopic dermatitis (AD) and to investigate molecular mechanisms of its increased release and retention. A Box-Behnken design determined the optimal formulation based on stability and in vitro skin retention. Evaluations included appearance, rheological properties, irritation, in vivo tissue distribution and pharmacodynamics. Molecular mechanisms of enhanced release were studied using high-speed centrifugation, molecular dynamics and rheology. The interaction between the CE, MF and skin was studied by tape stripping, CLSM, ATR-FTIR and SAXS. The formulation was optimized to contain 0.05% MF and used 10% polyglyceryl-3 oleate (POCC) as the CE. There was no significant difference from Elocon® cream in in vivo retention and pharmacodynamics but increased in vivo retention by 3.14-fold and in vitro release by 1.77-fold compared to the basic formulation. POCC reduced oil phase cohesive energy density, enhancing drug mobility and release. It disrupted skin lipid phases, aiding drug entry and formed hydrogen bonds, prolonging retention. This study highlights POCC as a CE in the cream, offering insights for semi-solid formulation development.

Efficacy of montelukast for adenoid hypertrophy in paediatrics: A systematic review and meta-analysis.

INTRODUCTION: Leukotrienes play a significant role in the pathogenesis of adenoid hypertrophy (A.H.). Therefore, we aimed to analyse the role of montelukast, a leukotriene receptor antagonist, alone or in combination with mometasone, a potent local intranasal steroid, for the treatment of A.H. METHODS: Participants were children with A.H. were treated with montelukast alone or montelukast and mometasone furoate. The main outcome measures were effect of montelukast on clinical symptoms of A.H. A literature review was conducted using online search engines, Cochrane Library, PubMed, Web of Science and Scopus, for randomized clinical trials assessing children with A.H. treated with montelukast alone or montelukast and mometasone furoate. Seven randomized clinical trials (RCTs) were included with 742 children. RESULTS: Our study reveals that montelukast alone or in combination with intranasal mometasone furoate significantly improves clinical symptoms of adenoid hypertrophy such as snoring, sleeping disturbance, mouth breathing and A/N ratio. Montelukast was superior to placebo in decreasing snoring (SMD = -1.00, 95% CI [-1.52, -0.49]), sleep discomfort (SMD = -1.26, 95% CI [-1.60, -0.93]), A/N ratio (MD = -0.11, 95% CI [-0.14, -0.09]) and mouth breathing (SMD = -1.36, 95% CI [-1.70, -1.02]). No difference was detected between montelukast and mometasone versus mometasone alone in snoring (SMD = -0.21, 95%CI [-0.69, 0.27]); however, the combination group was superior to the mometasone alone in mouth breathing (SMD = -0.46, 95% CI [-0.73, -0.19]). CONCLUSIONS: The limitation of studies included a small sample size, with an overall low to medium quality. Thus, further larger, higher-quality RCTs are recommended to provide more substantial evidence.

Highly sensitive liquid chromatography-mass spectrometry method for the quantitative analysis of mometasone furoate in human plasma: Method validation and application to clinical pharmacokinetic studies.

We report the development and the validation of a sensitive liquid chromatography-mass spectrometry (LC-MS/MS) method for mometasone furoate (MF) analysis in human plasma. Plasma samples were processed through liquid-liquid extraction and analyzed using LC-MS/MS operating in positive mode using multiple reaction monitoring of transitions m/z 520.9 â†’ 355.0 and m/z 525.8 â†’ 355.0 for MF and the internal standard (IS), respectively. Separation was achieved at 1.0 mL/min on a C18 column using a gradient elution of mobile phase of 0.05% ammonia in water (phase A) and acetonitrile (phase B). The assay range was 0.250-100 pg/mL and proved to be accurate and precise MF. Normalized recoveries were consistent and reproducible with a coefficient of variation (CV%) value of 6.0. The CV (%) of the IS normalized matrix factor was not observed in normal, lipemic, and hemolyzed plasmas. Dilutions of 1:10 were accurately quantified. A cycle of three freeze and thaw and stabilities at room temperature and on the autosampler were demonstrated. In addition, MF in the presence of indacaterol and glycopyrronium was proven to be stable at -70°C for at least 157 days. The present method was successfully applied to quantify MF in patients receiving MF, indacaterol, and glycopyrronium as a fixed-dose combination.

The impact of nasal use of azelastine and mometasone furoate on drug-induced sleep endoscopy.

OBJECTIVE: Endoscopic evaluation becomes difficult when excessive secretion/hypersalivation occurs in the upper airway. Intranasal corticosteroids and antihistamines reduce symptoms of rhinorrhea and nasal congestion. For this reason, in our study, we aimed to examine the effects of mometasone furoate and azelastine on both the amount of secretion and upper airway obstruction in terms of possible benefits during drug-induced sleep endoscopy (DISE). PATIENTS AND METHODS: A total of 92 patients participated in the study [69 (75%) were males and 23 (25%) were females]. Three groups in Group 1 used intranasal mometasone furoate for 30 days, Group 2 used intranasal azelastine for 30 days, and Group 3 did not use any nasal spray for 30 days. Then, DISE was performed on all patients on the 30th day. Upper airway obstructions detected in DISE were interpreted according to the VOTE classification. Furthermore, the amount of secretion and patients' tolerance levels observed during DISE were also assessed. RESULTS: Multilevel obstruction was detected in 94.5% of all patients participating in the study. Tolerance was poor in 18 (19.5%) of the patients participating in the study. Better DISE tolerance was determined in the female gender. DISE tolerance was also better in underweight and normal-weight patients (BMI < 25). CONCLUSIONS: This study first investigated nasal mometasone furoate and azelastine on DISE. This study showed that prior use of nasal mometasone furoate or azelastine before DISE did not affect the amount of secretion, tolerance level, severity, and configuration of obstruction.

Allergic Rhinitis: A Review.

Importance: Allergic rhinitis affects an estimated 15% of the US population (approximately 50 million individuals) and is associated with the presence of asthma, eczema, chronic or recurrent sinusitis, cough, and both tension and migraine headaches. Observations: Allergic rhinitis occurs when disruption of the epithelial barrier allows allergens to penetrate the mucosal epithelium of nasal passages, inducing a T-helper type 2 inflammatory response and production of allergen-specific IgE. Allergic rhinitis typically presents with symptoms of nasal congestion, rhinorrhea, postnasal drainage, sneezing, and itching of the eyes, nose, and throat. In an international study, the most common symptoms of allergic rhinitis were rhinorrhea (90.38%) and nasal congestion (94.23%). Patients with nonallergic rhinitis present primarily with nasal congestion and postnasal drainage frequently associated with sinus pressure, ear plugging, muffled sounds and pain, and eustachian tube dysfunction that is less responsive to nasal corticosteroids. Patients with seasonal allergic rhinitis typically have physical examination findings of edematous and pale turbinates. Patients with perennial allergic rhinitis typically have erythematous and inflamed turbinates with serous secretions that appear similar to other forms of chronic rhinitis at physical examination. Patients with nonallergic rhinitis have negative test results for specific IgE aeroallergens. Intermittent allergic rhinitis is defined as symptoms occurring less than 4 consecutive days/week or less than 4 consecutive weeks/year. Persistent allergic rhinitis is defined as symptoms occurring more often than 4 consecutive days/week and for more than 4 consecutive weeks/year. Patients with allergic rhinitis should avoid inciting allergens. In addition, first-line treatment for mild intermittent or mild persistent allergic rhinitis may include a second-generation H1 antihistamine (eg, cetirizine, fexofenadine, desloratadine, loratadine) or an intranasal antihistamine (eg, azelastine, olopatadine), whereas patients with persistent moderate to severe allergic rhinitis should be treated initially with an intranasal corticosteroid (eg, fluticasone, triamcinolone, budesonide, mometasone) either alone or in combination with an intranasal antihistamine. In contrast, first-line therapy for patients with nonallergic rhinitis consists of an intranasal antihistamine as monotherapy or in combination with an intranasal corticosteroid. Conclusions and Relevance: Allergic rhinitis is associated with symptoms of nasal congestion, sneezing, and itching of the eyes, nose, and throat. Patients with allergic rhinitis should be instructed to avoid inciting allergens. Therapies include second-generation H1 antihistamines (eg, cetirizine, fexofenadine, desloratadine, loratadine), intranasal antihistamines (eg, azelastine, olopatadine), and intranasal corticosteroids (eg, fluticasone, triamcinolone, budesonide, mometasone) and should be selected based on the severity and frequency of symptoms and patient preference.

Clinical safety and efficacy of a single-dose gentamicin, posaconazole and mometasone furoate otic suspension for treatment of canine otitis externa.

BACKGROUND: A single-dose, in-clinic, veterinary professional-administered treatment for canine otitis externa was developed to improve compliance and canine welfare. METHODS: This multicentre, controlled, examiner-masked, randomised field trial was conducted in 316 dogs over 42 days. Dogs were treated once, on day 0, with the investigational product containing gentamicin, posaconazole and mometasone furoate (Mometamax Ultra [MU]) or twice (days 0 and 7) with a control product containing florfenicol, terbinafine and betamethasone acetate (CP). The primary endpoint was a composite otitis index score of 4 or less (of 12) on day 14 and 3 or less (of 12) on day 28. RESULTS: On day 28, treatment success was recorded in 128 of 143 MU-treated dogs (89.5%), significantly non-inferior to 116 of 133 (87.2%) CP-treated dogs (Farrington-Manning test, Z = 4.1351, p < 0.0001). For mixed cultures of Staphylococcus pseudintermedius and Malassezia pachydermatis, there was 100% treatment success in MU-treated dogs (n = 33), significantly non-inferior to 90.2% (37 of 41) in CP-treated dogs (Farrington-Manning test, Z = 3.1954, p = 0.0007). LIMITATIONS: Efficacy in chronic otitis externa cases was not investigated. Cytology was not used to aid in diagnosis or for identification of secondary pathogens. CONCLUSION: This unique combination, single-dose product is safe and effective in dogs with otitis externa. It offers enhanced compliance, canine welfare and quality of life by eliminating the owner burden of treating this painful condition.

Pharmacological interventions for pediatric obstructive sleep apnea (OSA): Network meta-analysis.

IMPORTANCE: Pediatric obstructive sleep apnea (OSA) is a common disease that can have significant negative impacts on a child's health and development. A comprehensive evaluation of different pharmacologic interventions for the treatment of OSA in children is still lacking. OBJECTIVE: This study aims to conduct a comprehensive systematic review and network meta-analysis of pharmacological interventions for the management of obstructive sleep apnea in pediatric population. DATA SOURCES: PubMed, Web of Science, Embase, The Cochrane Library, and CNKI were searched from 1950 to November 2022 for pediatric OSA. STUDY SELECTION: Multiple reviewers included Randomized controlled trials (RCTs) concerning drugs on OSA in children. DATA EXTRACTION AND SYNTHESIS: Multiple observers followed the guidance of the PRISMA NMA statement for data extraction and evaluation. Bayesian network meta-analyses(fixed-effect model) were performed to compare the weighted mean difference (WMD), logarithmic odds ratios (log OR), and the surface under the cumulative ranking curves (SUCRA) of the included pharmacological interventions. Our protocol was registered in PROSPERO website (CRD42022377839). MAIN OUTCOME(S) AND MEASURE(S): The primary outcomes were improvements in the apnea/hypopnea index (AHI), while secondary outcomes included adverse events and the lowest arterial oxygen saturation (SaO2). RESULTS: 17 RCTs with a total of 1367 children with OSA aged 2-14 years that met the inclusion criteria were eventually included in our systematic review and network meta-analysis. Ten drugs were finally included in the study. The results revealed that Mometasone + Montelukast (WMD-4.74[95%CrIs -7.50 to -2.11], Budesonide (-3.45[-6.86 to -0.15], and Montelukast(-3.41[-5.45 to -1.39] exhibited significantly superior therapeutic effects compared to the placebo concerning apnea hypopnea index (AHI) value with 95%CrIs excluding no effect. Moreover, Mometasone + Montelukast achieved exceptionally high SUCRA values for both AHI (85.0 %) and SaO2 (91.0 %). CONCLUSIONS AND RELEVANCE: The combination of mometasone furoate nasal spray and oral montelukast sodium exhibits the highest probability of being the most effective intervention. Further research is needed to investigate the long-term efficacy and safety profiles of these interventions in pediatric patients with OSA.

Management of pediatric choanal atresia restenosis and subglottic stenosis using steroid-eluting stents.

OBJECTIVES: To depict the novel use of steroid-eluting stents in the treatment of choanal atresia (CA) restenosis and subglottic stenosis (SGS). METHODS: A retrospective chart review of three pediatric patients, one with CA and two with SGS, treated with mometasone furoate eluting mini stents (PROPEL) was performed. Patients were evaluated for restenosis and adverse events between one to twelve months postoperatively. RESULTS: Postoperatively, patient one with CA showed no signs of restenosis and required no further intervention. Patient two with SGS demonstrated an open subglottic lumen with no signs of restenosis as well as improved phonation following his planned serial procedures. Post-operatively, patient three with SGS exhibited no restenosis of the subglottic lumen, tolerated intermittent tracheostomy capping, and demonstrated improved phonation. CONCLUSION: In this case series, we outline successful treatments for the management of CA restenosis and SGS with mometasone furoate-eluting stents. To our knowledge, this is the first reported application of this treatment in pediatric patients with CA restenosis and the second reported application in pediatric patients with SGS.

Different Eco-Friendly Spectrophotometric Approaches Including Direct and Manipulations of Zero and Ratio Spectra for Simultaneous Determination of Novel Nasal Spray Combination Used in Seasonal Allergic Rhinitis.

BACKGROUND: The presentation of rhinitis has drawn increasing attention in recent years due to the possibility of overlap or confusion between allergic rhinitis symptoms and those of COVID-19. Azelastine hydrochloride (AZH) and mometasone furoate (MOF) are two of the most efficient combinations for enhancing the symptoms of seasonal allergic rhinitis. OBJECTIVE: This work concerns applying and validating different accurate and simple spectrophotometric approaches for simultaneous quantification of the binary mixture of AZH and MOF in raw material, laboratory-prepared mixtures, and pharmaceutical preparation. Moreover, assessment of the environmental impact of the applied approaches on the environment was also a key goal of this study. METHODS: AZH was determined using the direct spectrophotometric (D0) method, while four reliable spectrophotometric approaches namely, induced dual wavelength (IDW), ratio subtraction (RS), ratio difference (RD), and ratio derivative (1DD) were used for MOF determination. RESULTS: The methods were validated in line with the International Conference of Harmonization standards. In the AZH range of (5-56 µg/mL) and MOF range of (2-20 µg/mL), the linearity of the proposed approaches was investigated with high accuracy findings. There were no significant differences between the obtained results and those of the reported method when compared statistically. Furthermore, the applied spectrophotometric methods were deemed to be eco-friendly according to Green Analytical Procedure Index (GAPI) and Analytical Greenness Calculator (AGREE) assessment metrics. CONCLUSIONS: The applied spectrophotometric methods are simpler, more eco-friendly, and take a shorter time to precisely estimate many measurements compared to the only reported chromatographic analysis. HIGHLIGHTS: Neither publications of novel spectrophotometric methods nor reported green ones have been available for simultaneous determination of the binary mixture of AZH and MOF, so this work has a great significance and novelty in the area of pharmaceutical analysis.

Digitally monitored inhaled therapy: a 'smart' way to manage severe asthma?

INTRODUCTION: One of the fundamental challenges of managing patients with severe asthma is treatment adherence, particularly with inhaled corticosteroids. Adherence is difficult to measure objectively and poor adherence is associated with worse outcomes. In this study, assess the ability of a 'smart' inhaler to record adherence in severe asthma patients and measure the impact of this on asthma control. METHODS: Consecutive consenting patients meeting criteria for biologics had their existing high-dose ICS/LABA//LAMA combination inhaler/s switched to mometasone/indacaterol/glycopyrronium (114/46/136). Routine clinical data, including blood eosinophils, FeNO, and ACQ-6 scores were collected at baseline and at 4 wk. Adherence was then checked on the Propeller Health app, and good adherence was defined as >80% of prescribed usage. Participants were then followed-up at 12 months to record the proportion of patients who were initiated on biologics. RESULTS: 77 patients (mean [SD] age = 50.4 [15.7] years, 67.5% female [n = 52]) participated. 71 participants were able to use the device and 65% (n = 46) of these attained good asthma control and were not initiated on biologics at 12-month follow-up. Both groups demonstrated a significant reduction in ACQ6 score at follow-up (2.81 vs. 1.92, p < 0.001 and 3.05 vs. 2.60, p < 0.001, respectively), but there was no statistically significant difference in improvement between groups. Patients with optimal adherence also demonstrated a significant reduction in median FeNO at follow-up (47 ppb vs. 40 ppb, p = 0.003). CONCLUSIONS: In severe asthma patients, 'smart' inhalers may represent an effective management tool to improve adherence and asthma control, therefore avoiding the need for patients to commence biological therapies.

Maximal medical treatment of adenoid hypertrophy: a prospective study of preschool children.

PURPOSE: This study aimed to examine the effectiveness of the combined maximal medical treatment for adenoid hypertrophy in preschool children. METHODS: Sixty-four children underwent one-year combined therapy with intranasal mometasone furoate, oral desloratadine, nasal saline irrigation, and bacteriotherapy. Additionally, decongestion drops were applied during scheduled breaks. RESULTS: Of the 64 treated children, 72% showed clinical improvement in adenoid symptoms while 28% did not improve and underwent surgery. These groups differed significantly in terms of the overall reduction in ailments after treatment (p < 0.001), infection rate (p < 0.001), catarrh severity (p < 0.001) and nasal patency (p < 0.001). Endoscopic examination confirmed that responders experienced, on average, a decrease of 8.4% in the adenoid/choana ratio and an improvement in mucosal coverage of the adenoid. These effects were not observed in the group of children whose parents opted for surgery after nine months of conservative treatment. CONCLUSIONS: The proposed new schema of long-term maximal medical treatment with the use of combined intermittent treatment of intranasal mometasone furoate and decongestion drops, oral desloratadine, nasal saline irrigation, and bacteriotherapy can be attempted in patients with adenoid hypertrophy symptoms, and responders may avoid the need for surgery. The applied treatment breaks resulted in a low number of therapeutic side effects.

[Clinical and pathological analysis of 345 cases of vulvar lichen sclerosus and a preliminary study on the frequency of maintenance treatment].

Objective: To analyze and summarize the clinical and pathological characteristics, management, and efficacy of patients with vulvar lichen sclerosus (VLS) through a single center large sample study, and preliminarily to explore the frequency of maintenance treatment medication for VLS. Methods: The clinical data of VLS patients in Obstetrics and Gynecology Hospital of Fudan University from 2018 to 2021 were retrospectively collected. The clinicopathological characteristics (patients' age, course of disease, complicated disease history, family history, symptoms, signs and pathology), treatment and effects were retrospectively analyzed. The patients in the maintenance treatment stage were followed up regularly to explore the minimum frequency of individual medication to maintain the stability of the disease. Results: (1) General situation: a total of 345 patients with VLS were included in this study. The average age was (50.4±14.7) years (ranged from 8 to 84 years old), prevalence was highest in the 50-59 years group (30.1%, 104/345). Immune diseases occurred in 18.6% (33/177) of patients, 24.3% (43/177) of patients had allergic skin diseases, and 5.6% (10/177) of the patients' immediate family members had chronic vulvar pruritus or vulvar hypopigmentation. (2) Clinical features: the most common symptom was vulvar pruritus (96.1%, 196/204) among 204 patients with recorded symptoms. The most common sign was hypopigmentation of the vulva (96.3%, 206/214). The most common involved sites were labia minora (70.3%, 142/202), labia majora (67.8%, 137/202), and labial sulcus (59.4%, 120/202). The cumulative number of sites involved in 62 vulvar atrophy patients (2.7±1.1) was significantly higher than that in 152 non-atrophy patients (2.2±1.0; t=3.48, P=0.001). The course of vulvar atrophy was (9.3±8.5) years, which was significantly longer than that of non-atrophy patients [(6.6±5.6) years; t=2.04, P=0.046]. (3) Pathological features: among the 286 patients with electronic pathological sections, the most common pathological feature in the epidermis was epithelial nail process passivation (71.3%, 204/286). The common pathological features in the dermis were interstitial collagenization (84.6%, 242/286), and inflammatory cell infiltration (73.8%, 211/286). (4) Treatment: 177 patients received standardized treatment after diagnosis and were followed up regularly in our hospital. In the initial treatment stage, 26.0% (46/177) of the patients were treated with 0.05% clobetasol propionate cream, and 74.0% (131/177) of the patients were treated with 0.1% mometasone furoate ointment. The complete remission rates of the two methods were respectively 80.4% (37/46) and 74.0% (97/131), and there was no statistically significant difference (χ²=0.76, P=0.385). During maintenance treatment, 27.1% (48/177) of the patients took the medication twice a week, 35.0% (62/177) took the medication once a week, and 37.9% (67/177) took the medication once every 10 days. During follow-up after 6 months of maintenance treatment, there were no patients with recurrence of pruritus or progression of vulvar signs. Conclusions: The majority of VLS patients have itching, hypopigmentation, involvement of labia minora and labia majora, progressive atrophy, and inflammatory infiltration of dermis. Local treatments of mometasone furoate and clobetasol propionate have good initial therapeutic effects. The frequency exploration of individualized maintenance treatment could minimize the occurrence of adverse reactions when ensuring the stability of the patients' condition.

Intranasal combo: fixed-dose combination of mometasone furoate and olopatadine hydrochloride in therapeutic strategies for rhinosinusitis.

A novel strategy for the treatment of allergic rhinitis results from the innovative combination of antihistamine and intranasal corticosteroid drugs. By combining two preparations with different mechanism of action, this novel approach facilitates quick and effective controls of all upper respiratory tract allergy symptoms. The article presents the results of a study of olopatadine hydrochloride and mometasone furoate fixed-dose combination (GSP301) administered intranasally from a spray formulation, with an attempt at positioning the treatment within the ARIA and EPOS guidelines.

Mometasone furoate nasal spray in Italian children with seasonal allergic rhinitis: a comprehensive assessment

Objective: Seasonal allergic rhinitis (SAR) is a common disease of childhood and is charac-terized by type 2 inflammation, bothersome symptoms, and impaired quality of life (QoL). Intranasal corticosteroids are effective medications in managing SAR. In addition, mometa-sone 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 signifi-cantly dampen type 2 inflammation, improve QoL, and reduce severity of symptoms in Italian children with SAR, and was safe (AU)

Effect of topical corticosteroids on nasal patency after acute positive airway pressure exposure / Efeito dos corticosteroides tópicos na patência nasal após exposição aguda à pressão positiva nas vias aéreas

Abstract Introduction Nasal congestion and obstruction are reported in the majority of continuous positive airway pressure users and are frequently cited as reasons for noncompliance. Baseline inflammation due to allergic rhinitis could increase or exacerbate the inflammatory effect of high airflow in the nasal cavity as the result of continuous positive airway pressure and lead to greater continuous positive airway pressure intolerance. In this setting, intranasal steroids would be expected to counteract the nasal inflammation caused by allergic rhinitis and/or continuous positive airway pressure. Objective The aim of the present study is to evaluate the effects of topical corticosteroid use on nasal patency after acute exposure to positive pressure. Methods Ten individuals with allergic rhinitis were exposed to 1 h of continuous airway pressure (15 cm H2O) in the nasal cavity, delivered by a continuous positive airway pressure device. Visual analog scale, nasal obstruction symptom evaluation scale, acoustic rhinometry and peak nasal inspiratory flow were performed before and after the intervention. After 4 weeks topical nasal steroid (budesonide) application, positive pressure exposure was repeated as well as the first assessments. Results Patients reported a statistically significant improvement both on the visual analog (p = 0.013) and obstruction symptom evaluation scales (p < 0.01). Furthermore, objective measurements were improved as well, with increased nasal cavity volume on acoustic rhinometry (p = 0.02) and increased peak nasal inspiratory flow (p = 0.012), after corticosteroid treatment. Conclusion In patients with allergic rhinitis, intranasal corticosteroid therapy improved objective and subjective parameters of nasal patency after acute exposure of the nasal cavity to positive pressure.

Resumo Introdução Congestão e obstrução nasais são relatadas na maioria dos usuários de pressão positiva contínua nas vias aéreas e são frequentemente mencionadas como razões para a falta de aderência. A inflamação basal devida à rinite alérgica pode aumentar ou agravar o efeito inflamatório do alto fluxo de ar na cavidade nasal como resultado da pressão positiva contínua nas vias aéreas e aumentar a intolerância à mesma. Nesse cenário, espera-se que os esteróides intranasais neutralizem a inflamação nasal causada pela rinite alérgica e/ou pela pressão positiva contínua nas vias aéreas. Objetivo Avaliar os efeitos do uso tópico de corticosteroides na patência nasal após exposição aguda à pressão positiva. Métodos Dez indivíduos com rinite alérgica foram expostos a uma hora de pressão contínua nas vias aéreas (15 cm H2O) na cavidade nasal, fornecida por um dispositivo de pressão positiva contínua nas vias aéreas. A escala visual analógica, a escala Nasal Obstruction Symptom Evaluation, rinometria acústica e pico de fluxo inspiratório nasal foram aplicados antes e após a intervenção. Após 4 semanas de aplicação tópica de esteroide nasal (budesonida), a exposição positiva à pressão foi repetida, bem como as primeiras avaliações. Resultados Os pacientes relataram uma melhoria estatisticamente significante tanto na escala visual analógica (p = 0,013) quanto na escala Nasal Obstruction Symptom Evaluation (p < 0,01). Além disso, as medidas objetivas também foram melhoradas, com aumento do volume da cavidade nasal na rinometria acústica (p = 0,02) e aumento do pico de fluxo inspiratório nasal (p = 0,012), após o tratamento com corticosteroide. Conclusão Em pacientes com rinite alérgica, a terapia com corticosteroide intranasal melhorou os parâmetros objetivos e subjetivos da patência nasal após exposição aguda da cavidade nasal à pressão positiva.

Mometasone furoate intranasal spray is effective in reducing symptoms and adenoid size in children and adolescents with adenoid hypertrophy / El aerosol nasal de mometasona furoato es efectivo para reducir los síntomas y el tamaño de las adenoides en niños y adolescentes con hipertrofia adenoidea

INTRODUCTION: The use of mometasone furoate (MF) intranasal spray in treating adenoid hypertrophy (AH) has a variable outcome due the different methods of adenoid size evaluation. The aim of our study was to evaluate the effect of MF intranasal spray in children and adolescents with AH using a reliable and consistent endoscopic evaluation. MATERIAL AND METHOD: A prospective interventional study was conducted. Evaluation took place during the first visit (week 0) and second visit (week 12). Symptoms of nasal obstruction, rhinorrhoea, cough and snoring were assessed, and an overall total symptoms score was obtained. A rigid nasoendoscopic examination using a four-grading system of adenoid size from 1 to 4 was performed. Patients were treated with MF intranasal spray for 12 weeks. Patients' aged 7-11-years old used 1 spray in each nostril once daily, while patients aged 12-17 used two sprays in each nostril once daily. Reassessment was carried out during the second visit (week 12). RESULTS: A total of 74 patients was recruited. There were significant improvements from week 0 to week 12 in the symptoms' score for nose obstruction, rhinorrhoea, cough, snoring including the total nasal symptoms' score (p < 0.001). AH significantly reduced in size from week 0 (2.89±.87) to week 12 (1.88±.83) (p < 0.001). CONCLUSION: MF intranasal spray is effective in improving the symptoms attributed to AH as well as reducing the adenoid size. MF intranasal spray is advocated as a treatment option before adenoidectomy is considered

INTRODUCCIÓN: El papel del aerosol nasal de mometasona furoato (MF) para tratar la hipertrofia adenoidea (HA) tiene un resultado variable, debido a los diferentes métodos de evaluación del tamaño de las adenoides. El objetivo de nuestro estudio fue evaluar el efecto del aerosol nasal de MF en niños y adolescentes con HA, utilizando una evaluación endoscópica fiable y consistente. MATERIAL Y MÉTODO: Se llevó a cabo un estudio prospectivo intervencionista. La evaluación se realizó durante la primera visita (semana 0) y la segunda visita (semana 12). Se valoraron los síntomas de obstrucción nasal, rinorrea, tos y ronquidos, obteniéndose una puntuación de síntomas totales globales. Se realizó un examen nasoendoscópico rígido utilizando un sistema de clasificación del tamaño adenoideo, con valores de 1 a 4. Los pacientes fueron tratados con aerosol intranasal de MF durante 12 semanas. Los pacientes con edades comprendidas entre 7 y 11 años utilizaron 1 pulverización en cada fosa nasal una vez al día, mientras que los pacientes de 12 a 17 años utilizaron 2 pulverizaciones en cada fosa nasal una vez al día. La re-evaluación se realizó durante la segunda visita (semana12). RESULTADOS: Reunimos a un total de 74 pacientes. Se produjeron mejoras significativas de la semana 0 a la 12 en cuanto a puntuación de los síntomas de obstrucción nasal, rinorrea, tos y ronquidos, incluyendo la puntuación total de síntomas nasales (p < 0,001). Se redujo significativamente el tamaño de HA de la semana 0 (2,89 ±0,87) a la semana 12 (1,88 ±0,83) (p < 0,001). CONCLUSIÓN: El aerosol intranasal de MF es efectivo para mejorar los síntomas atribuidos a HA, así como reducir el tamaño de las adenoides. Se propone el uso de dicho aerosol intranasal como opción de tratamiento, antes de considerarse la adenoidectomía

Individualized treatment for allergic rhinitis based on key nasal clinical manifestations combined with histamine and leukotriene D4 levels / Tratamento individualizado para a rinite alérgica baseado nas principais manifestações clínicas nasais e dos níveis de histamina e leucotrieno D4

Abstract Introduction The types of allergic rhinitis are roughly classified based on the causative antigens, disease types, predilection time, and symptom severity. Objective To examine the clinical typing and individualized treatment approach for allergic rhinitis and to determine the optimal treatment method for this disease using various drug combination therapies. Methods A total of 108 participants with allergic rhinitis were divided into three groups based on symptoms. Subsequently, each group was further categorized into four subgroups based on the medications received. The efficacy of the treatments was evaluated using the visual analog scale VAS scores of the total and individual nasal symptoms, decline index of the symptom score, histamine and leukotriene levels, and mRNA and protein expression levels of histamine 1 and cysteinyl leukotriene 1 receptors. Results Loratadine + mometasone furoate and loratadine + mometasone furoate + montelukast significantly improved the sneezing symptom and reduced the histamine levels compared with the other combination therapies (p < 0.05). Meanwhile, montelukast + mometasone furoate and montelukast + mometasone furoate + loratadine considerably improved the nasal obstruction symptom and decreased the leukotriene D4 levels compared with the other combination therapies (p < 0.05). Conclusion Clinical symptom evaluation combined with experimental detection of histamine and leukotriene levels can be an objective and accurate method to clinically classify the allergic rhinitis types. Furthermore, individualized treatment based on allergic rhinitis classification can result in a good treatment efficacy.

Resumo Introdução A rinite alérgica é basicamente classificada de acordo com os antígenos causadores, tipos de doença, peridiocidade e gravidade dos sintomas. Objetivo Avaliar os tipos clínicos e a abordagem terapêutica individualizada para cada tipo de rinite alérgica e determinar o método de tratamento ideal utilizando várias terapias de combinação de fármacos. Método Um total de 108 participantes com rinite alérgica foram divididos em três grupos com base nos sintomas. Posteriormente, cada grupo foi subsequentemente categorizado em quatro subgrupos com base nos medicamentos recebidos. A eficácia dos tratamentos foi avaliada utilizando os escores da escala visual analógica EVA dos sintomas nasais totais e individualmente, índice de declínio do escore de sintomas, níveis de histamina e leucotrienos e níveis de expressão de mRNA e proteína dos receptores de histamina 1 e cisteinil-leucotrieno 1. Resultados As associações entre loratadina + furoato de mometasona, assim como a de loratadina + furoato de mometasona + montelucaste melhoraram significativamente o sintoma de espirros e reduziram os níveis de histamina em comparação às outras terapias combinadas (p < 0,05). Por outro lado, a associação montelucaste + furoato de mometasona, assim como a associação montelucaste + furoato de mometasone + loratadina melhoraram consideravelmente o sintoma de obstrução nasal e diminuíram os níveis de leucotrieno D4 em comparação com as outras combinações (p < 0,05). Conclusão A avaliação clínica dos sintomas combinada com a detecção experimental dos níveis de histamina e leucotrieno pode ser um método objetivo e preciso para classificar clinicamente os tipos de rinite alérgica. Além disso, o tratamento individualizado baseado na classificação da rinite alérgica pode resultar no aumento da eficácia do tratamento.
