INTRODUCTION
Atopic dermatitis (AD) is one of the most common chronic skin conditions affecting about 20% of children and 5% of adults. However, the studies assessing novel therapies for AD have been focused mainly on paediatric patients and only few studies have involved adult participants.
AIM
To compare the treatment outcomes between the antihistamine monotherapy and combined intervention with an antihistamine agent and a cysteinyl leukotriene receptor antagonist in adult patients with atopic dermatitis.
MATERIAL AND METHODS
Patients were randomized into two groups to receive 5 mg oral desloratadine or the combined therapy with 5 mg oral desloratadine and 10 mg montelukast. Both groups were also administered topical treatment using the same protocol (topical Elocon and moisturizer). To estimate the efficacy of the implemented therapy methods, different skin health scores (SCORAD, GISS, EASI, PPNRS and DLQI) and skin functional assessment outcomes (corneometry, pH and transepidermal water loss) were evaluated before and after the treatment.
RESULTS
Significant differences were revealed in compared measurement results for scales of the Extent and Severity of Eczema assessment, Global Individual Signs Score, Eczema Area and Severity Index, Pruritus Numerical Rating Scale, Dermatology Life Quality Index and Skin Functional Properties (p > 0.05).
CONCLUSIONS
Comparison of data presenting the therapy outcomes in two groups showed that administration of the combined therapy was significantly more effective compared to the antihistamine monotherapy. The results revealed considerable efficacy of the combined therapy reinforced by the use of cysteinyl leukotriene receptor antagonist, montelukast.

BACKGROUND
Diabetic nephropathy is a progressive condition and a leading cause of end-stage renal disease. Oxidative stress and inflammation play an important role in its pathogenesis. In pre-clinical studies, Montelukast had shown renoprotective and anti-oxidant properties, hence the study was planned to evaluate the effect of Montelukast in a Streptozotocin (STZ) induced model of diabetic nephropathy.
METHODS
40 Wistar rats of either sex were randomly divided into four groups . 1. Vehicle control group, 2. Enalapril (5 mg/kg), 3. Montelukast low-dose (10 mg/kg) and 4. High-dose (20 mg/kg) group. On day 1, diabetes was induced using a single dose of STZ (60 mg/kg) intraperitoneally. Diabetes induction was verified based on fasting blood glucose (FBG) levels on day 7 and from day 8 to day 42, rats were given study drugs. FBG, serum creatinine, blood urea nitrogen (BUN) and urine microalbumin levels were assessed pre-study and post-study. Assessments of kidney malondialdehyde (MDA), reduced glutathione (GSH) and renal histopathology were carried out at the end of the study.
RESULTS
Montelukast 10 mg/kg group showed significantly lower urine microalbumin levels compared to the vehicle control group (p < 0.05). Montelukast 20 mg/kg group showed significantly lower levels of FBG, serum creatinine, BUN and urine microalbumin compared to the vehicle control group (p < 0.05). In addition, Montelukast 20 mg/kg group also showed better effects on kidney MDA and GSH levels (p < 0.05) and histopathological scores compared to the vehicle control group.
CONCLUSION
Montelukast showed a protective effect in the model of diabetic nephropathy because of its antioxidant effect.

The wingless/integrase-1 (WNT) pathway involved in the pathogenesis of inflammatory airway diseases has recently generated considerable research interest. Montelukast, a leukotriene receptor antagonist, provides therapeutic benefits in allergic asthma involving eosinophils. We aimed to investigate the role of the WNT pathway in the therapeutic actions of montelukast (MT) in a mixed type of allergic-acute airway inflammation model induced by ovalbumin (OVA) and lipopolysaccharide (LPS) in mice. Female mice were sensitized with intraperitoneal OVA-Al(OH) administration in the initiation phase and intranasal OVA followed by LPS administration in the challenge phase. The mice were divided into eight groups: control, asthmatic, and control/asthmatic treated with XAV939 (inhibitor of the canonical WNT pathway), LGK-974 (inhibitor of the secretion of WNT ligands), or MT at different doses. The inhibition of the WNT pathway prevented tracheal 5-HT and bradykinin hyperreactivity, while only the inhibition of the canonical WNT pathway partially reduced 5-HT and bradykinin contractions compared to the inflammation group. Therefore, MT treatment hindered 5-HT and bradykinin hyperreactivity associated with airway inflammation. Furthermore, MT prevented the increases in the phosphorylated GSK-3β and WNT5A levels, which had been induced by airway inflammation, in a dose-dependent manner. Conversely, the MT application caused a further increase in the fibronectin levels, while there was no significant alteration in the phosphorylation of the Smad-2 levels in the isolated lungs of the mice. The MT treatment reversed the increase in the mRNA expression levels of interleukin-17A. An increase in eosinophil and neutrophil counts was observed in bronchoalveolar lavage fluid samples obtained from the mice in the inflammation group, which was hampered by the MT treatment. The inhibition of the WNT pathway did not alter inflammatory cytokine expression or cell infiltration. The WNT pathway mediated the therapeutic effects of MT due to the inhibition of GSK-3β phosphorylation as well as the reduction of WNT5A levels in a murine airway inflammation model.

The Journal of Dermatological Treatment Dec 2024There is a lack of real-life safety data on treatment options for chronic urticaria in the presence of comedication and comorbidities.
BACKGROUND
There is a lack of real-life safety data on treatment options for chronic urticaria in the presence of comedication and comorbidities.
METHODS
We present a single-center UCARE pilot study of 212 outpatients with chronic urticaria. Patients were divided into three groups according to different CU therapies according to international guidelines.
RESULTS
Of 212 patients, 108 (mean age 48.9 years, 71.3% female) had 59 comorbidities, including cardiovascular, autoimmune and malignant diseases. Patients were followed for a mean of 24.6 months (SD ± 21.3). Urticaria therapies were divided into three groups: A: 105 (97.2%) with omalizumab and 2nd generation antihistamines), B: 16 patients (14.8%): dual therapy with antihistamines and cyclosporine in 10 (9.3%), montelukast in five (4. 6%), dapsone in four (3.7%), hydroxychloroquine in one patient (0.9%), C: 12 (11.1%) patients received a third drug for 4.9 months (SD ± 3.2) and one quadruple therapy (2.1 months). 10 out of 12 (83.3%) patients received montelukast, two (16.7%) cyclosporine, two (16.7%) dapsone and one (8.3%) hydroxychloroquine as a third drug for chronic urticaria.
CONCLUSIONS
Combining treatment modalities for chronic urticaria and comorbidities are available and feasible with a good safety profile.

Review
A review of the therapeutic potential of the cysteinyl leukotriene antagonist Montelukast in the treatment of bronchiolitis obliterans syndrome following lung and hematopoietic-stem cell transplantation and its possible mechanisms.
Lung and hematopoietic stem cell transplantation are therapeutic modalities in chronic pulmonary and hematological diseases, respectively. One of the complications in these patients is the development of bronchiolitis obliterans syndrome (BOS). The efficacy and safety of available treatment strategies in BOS remain a challenge. A few mechanisms have been recognized for BOS in lung transplant and graft--host disease (GVHD) patients involving the TH-1 and TH-2 cells, NF-kappa B, TGF-b, several cytokines and chemokines, and cysteinyl leukotrienes (CysLT). Montelukast is a highly selective CysLT receptor antagonist that has been demonstrated to exert anti-inflammatory and anti-fibrotic effects in abundant experiments. One area of interest for the use of montelukast is lung transplants or GVHD-associated BOS. Herein, we briefly review data regarding the mechanisms involved in BOS development and montelukast administration as a treatment modality for BOS, and finally, the possible relationship between CysLTs antagonism and BOS improvement will be discussed.

Meta-Analysis Review
This meta-analysis aims to assess the clinical effectiveness of combination therapy with montelukast sodium for the treatment of cough variant asthma (CVA) in children, intending to provide clinical evidence and data to guide the selection of clinical therapy. A literature review was conducted using numerous databases, including China National Knowledge Infrastructure (CNKI), Wanfang database, Embase, PubMed, and Web of Science, from inception to December 2023. Trials meeting the criteria for the combined treatment of montelukast sodium for CVA in children were included. Stata 16.0 software was utilized for meta-analysis. The combined treatment group received montelukast sodium in addition to the control group, while the control group received budesonide, fluticasone propionate, salmeterol-fluticasone, or ketotifen alone. This investigation included 18 papers. All subjects were from the Chinese population. Compared to the control group, the combined treatment group demonstrated a higher effective rate (relative ratio [RR] = 1.23, 95% confidence interval [CI]: 1.18-1.29, p < .001), but no difference in the incidence of adverse reactions (RR = 0.65, 95% CI: 0.42-1.02, p = .060) after treatment. Moreover, the peak expiratory flow (PEF) (SMD = 1.69, 95% CI: 1.09-2.30, p < .001), forced vital capacity (FVC) (SMD = 1.67, 95% CI: 0.94-2.39, p < .001), forced expiratory volume in 1 s (FEV1) (SMD = 1.74, 95% CI: 1.09-2.40, p < .001), and FEV1/FVC (SMD = 1.84, 95% CI: 0.41-3.28, p = .012) were significantly higher in the combined treatment group than in the control group after treatment. Compared with the control group, the levels of tumor necrosis factor-α (SMD = -2.38, 95% CI: -3.22 to -1.55, p < .001), IL-4 (SMD = -2.65, 95% CI: -3.26 to -2.04, p < .001), and IgE (SMD = -2.98, 95% CI: -3.24 to -2.72, p < .001) were significantly lower in the combined treatment group after treatment. The combined use of montelukast sodium in the treatment of pediatric CVA in China is associated with a significant clinical effect, making it a reasonable therapeutic approach.

Four chemometric models enhanced by Latin hypercube sampling design for quantification of anti-COVID drugs: sustainability profiling through multiple greenness, carbon footprint, blueness, and whiteness metrics.
Montelukast sodium (MLK) and Levocetirizine dihydrochloride (LCZ) are widely prescribed medications with promising therapeutic potential against COVID-19. However, existing analytical methods for their quantification are unsustainable, relying on toxic solvents and expensive instrumentation. Herein, we pioneer a green, cost-effective chemometrics approach for MLK and LCZ analysis using UV spectroscopy and intelligent multivariate calibration. Following a multilevel multifactor experimental design, UV spectral data was acquired for 25 synthetic mixtures and modeled via classical least squares (CLS), principal component regression (PCR), partial least squares (PLS), and genetic algorithm-PLS (GA-PLS) techniques. Latin hypercube sampling (LHS) strategically constructed an optimal validation set of 13 mixtures for unbiased predictive performance assessment. Following optimization of the models regarding latent variables (LVs) and wavelength region, the optimum root mean square error of cross-validation (RMSECV) was attained at 2 LVs for the 210-400 nm spectral range (191 data points). The GA-PLS model demonstrated superb accuracy, with recovery percentages (R%) from 98 to 102% for both analytes, and root mean square error of calibration (RMSEC) and prediction (RMSEP) of (0.0943, 0.1872) and (0.1926, 0.1779) for MLK and LCZ, respectively, as well bias-corrected mean square error of prediction (BCMSEP) of -0.0029 and 0.0176, relative root mean square error of prediction (RRMSEP) reaching 0.7516 and 0.6585, and limits of detection (LOD) reaching 0.0813 and 0.2273 for MLK and LCZ respectively. Practical pharmaceutical sample analysis was successfully confirmed via standard additions. We further conducted pioneering multidimensional sustainability evaluations using state-of-the-art greenness, blueness, and whiteness tools. The method demonstrated favorable environmental metrics across all assessment tools. The obtained Green National Environmental Method Index (NEMI), and Complementary Green Analytical Procedure Index (ComplexGAPI) quadrants affirmed green analytical principles. Additionally, the method had a high Analytical Greenness Metric (AGREE) score (0.90) and a low carbon footprint (0.021), indicating environmental friendliness. We also applied blueness and whiteness assessments using the high Blue Applicability Grade Index (BAGI) and Red-Green-Blue 12 (RGB 12) algorithms. The high BAGI (90) and RGB 12 (90.8) scores confirmed the method's strong applicability, cost-effectiveness, and sustainability. This work puts forward an optimal, economically viable green chemistry paradigm for pharmaceutical quality control aligned with sustainable development goals.

Chronic graft--host disease (cGvHD) is a common complication after allogeneic haematopoietic stem cell transplantation, characterised by a broad disease spectrum that can affect virtually any organ. Although pulmonary cGvHD is a less common manifestation, it is of great concern due to its severity and poor prognosis. Optimal management of patients with pulmonary cGvHD is complicated and no standardised approach is available. The purpose of this joint European Respiratory Society (ERS) and European Society for Blood and Marrow Transplantation task force was to develop evidence-based recommendations regarding the treatment of pulmonary cGvHD phenotype bronchiolitis obliterans syndrome in adults. A multidisciplinary group representing specialists in haematology, respiratory medicine and methodology, as well as patient advocates, formulated eight PICO (patient, intervention, comparison, outcome) and two narrative questions. Following the ERS standardised methodology, we conducted systematic reviews to address these questions and used the Grading of Recommendations Assessment, Development and Evaluation approach to develop recommendations. The resulting guideline addresses common therapeutic options (inhalation therapy, fluticasone-azithromycin-montelukast, imatinib, ibrutinib, ruxolitinib, belumosudil, extracorporeal photopheresis and lung transplantation), as well as other aspects of general management, such as lung functional and radiological follow-up and pulmonary rehabilitation, for adults with pulmonary cGvHD phenotype bronchiolitis obliterans syndrome. These recommendations include important advancements that could be incorporated in the management of adults with pulmonary cGvHD, primarily aimed at improving and standardising treatment and improving outcomes.

INTRODUCTION
Adenoid hypertrophy is a common childhood disease; its standard treatment is adenoidectomy. The desire for medical management is increasing due to fewer complications and more convenience. The present study investigated the effect of adding oral montelukast to mometasone nasal spray in treating adenoid hypertrophy.
MATERIALS AND METHODS
This was a randomized, double-blind, placebo-controlled study conducted at a referral teaching hospital (Tehran, Iran) from September 2020 to September 2021. Children aged 2 to 14 years with clinical and radiological findings of adenoid hypertrophy were enrolled. Patients were randomly divided into two groups: mometasone nasal spray with oral montelukast (case group) or mometasone with placebo (control group). Then, the clinical scores were compared before and two months after the intervention.
RESULTS
Ninety-six patients completed the study [62.5% male (n=60)]. Of these, 51 were in the case and 45 in the control group. The clinical score in each group decreased significantly after the intervention (P<0.001), but the decrease in clinical score in the case group was not significantly different from the control (p=0.576).
CONCLUSION
The results showed that the combination therapy with mometasone and montelukast has the same efficacy as mometasone and placebo in treating adenoid hypertrophy. Adding montelukast to mometasone has no additional effect.

Meta-Analysis Review
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.
