Montelukast in paediatric asthma and allergic rhinitis: a systematic review and meta-analysis. Eur Respir Rev 2023; 32:230124. [PMID: 37852659 PMCID: PMC10582929 DOI: 10.1183/16000617.0124-2023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Accepted: 08/10/2023] [Indexed: 10/20/2023] Open
Abstract
BACKGROUND We aim to assess the impact of montelukast on paediatric patients with asthma/allergic rhinitis, measured using patient-reported outcome measures, compared with other treatments or placebo. METHODS Protocol registration CRD42020216098 (www.crd.york.ac.uk/PROSPERO). MEDLINE and Embase databases were used to conduct the search. Two authors independently selected studies and extracted data, and a third reviewer resolved discrepancies. Meta-analyses were constructed to estimate the standardised mean difference (SMD) using a random-effects model. RESULTS Out of 3937 articles identified, 49 studies met the inclusion criteria, mostly randomised clinical trials (sample sizes: 21-689 patients). The SMD of change pooled estimators for the global, mental and physical domains of health-related quality of life were not statistically significant. For daytime and night-time symptoms scores, the SMD (95% CI) was in favour of inhaled corticosteroids (-0.12, -0.20- -0.05 and -0.23, -0.41- -0.06, respectively). The pooled estimator for global asthma symptoms was better for montelukast when compared with placebo (0.90, 0.44-1.36). CONCLUSIONS The synthesis of the available evidence suggests that, in children and adolescents, montelukast was effective in controlling asthma symptoms when compared with placebo, but inhaled corticosteroids were superior in controlling symptoms, especially at night-time. These findings of our systematic review concur with current guidelines for asthma treatment.

Abstract
OBJECTIVE The global prevalence of allergic diseases has led to a negative and extensive impact on the health and lives of a large population of children. This study investigates the efficacy, acceptability, and safety of cetirizine (CTZ) for treating allergic diseases in children and provides evidence-based assertions for decision-making. METHODS PubMed, Embase, the Cochrane Library, World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov, and the European Union Clinical Trials Register were systematically searched from inception to April 21, 2022. Randomized controlled trials (RCTs) or quasi-RCTs of children with allergic diseases receiving CTZ compared with those receiving placebo or other drugs were included without language limitations. Two investigators independently identified articles, extracted data, conducted meta-analyses, assessed the Cochrane risk of bias of individual studies, and evaluated the evidence certainty using the Grading of Recommendations Assessment, Development, and Evaluation approach; any discrepancies were resolved by consulting with a third investigator. Primary outcomes included scales that evaluated the recovery of allergic conditions in AR, such as the total symptom score (TSS). Secondary outcomes included laboratory test changes, safety (adverse events, AEs), and quality of life (QOL). Data were pooled using the Cochrane Review Manager 5.4, and a fixed-effects model was used if heterogeneity was evaluated as low (I 2 < 50%); otherwise, a random-effects model was adopted. RESULTS A total of 22 studies (5,867 patients) were ultimately included [eight with perennial AR, six with seasonal AR, four with atopic dermatitis (AD), and four with other allergic diseases], most of which had a low or unclear risk of bias. Moderate certainty evidence showed that CTZ was found to benefit allergic symptom control [mean difference (MD) of TSS at 1 week: MD, -0.32 (-0.52, -0.12); at 2 weeks: MD, -0.25 (-0.35, -0.14); at 4 weeks: MD, -4.07 (-4.71, -3.43); at 8 weeks: MD, -4.22 (-4.73, -3.72); at 12 weeks: MD, -5.63 (-6.14, -5.13); all P-values were less than 0.05] and QOL [at 12 weeks: MD, -23.16 (-26.92, -19.39); P < 0.00001] in children with AR. It had similar efficacy compared with other antihistamines (AHs) or montelukast, without showing better control of AD severity in children. Moderate-to-low certainty evidence demonstrated that CTZ was well tolerated and did not increase the risk of severe and overall AEs, cardiotoxicity, damage to the central nervous and digestive systems, or other systems in children, except for the risk of somnolence [risk ratio, 1.62 (1.02, 2.57); P = 0.04, compared with placebo]. CONCLUSION Moderate-to-low certainty evidence revealed that CTZ could improve clinical improvement and QOL in children with AR and have comparable efficacy with other AHs. CTZ is well tolerated in the pediatric population, except for an increased risk of somnolence. SYSTEMATIC REVIEW REGISTRATION [https://www.crd.york.ac.uk/PROSPERO/], identifier [CRD42021262767].

Newer-generation antihistamines and the risk of adverse events in children: A systematic review. Pediatr Allergy Immunol 2021; 32:1533-1558. [PMID: 33894089 DOI: 10.1111/pai.13522] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2020] [Revised: 04/01/2021] [Accepted: 04/13/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND H1-antihistamines (AHs) are widely used for the treatment of allergic diseases, being one of the most commonly prescribed classes of medications in pediatrics. Newer-generation AHs are associated with fewer adverse effects compared with first-generation AHs. However, their relative harms in the pediatric population still need scrutiny. METHODS We performed a systematic review of randomized controlled trials (RCTs), which included comparisons of safety parameters between an orally administered newer-generation AH and another AH (first- or second-generation), montelukast, or placebo in children aged ≤12 years. We searched MEDLINE and CENTRAL, independently extracted data on study population, interventions, adverse events (AEs), and treatment discontinuations, and assessed the methodologic quality of the included RCTs using the Cochrane's risk of bias tool. RESULTS Forty-five RCTs published between 1989 and 2017 met eligibility criteria. The majority of RCTs included school-aged children with allergic rhinitis and had a follow-up period of up to a month. Four RCTs reported serious AEs in patients receiving a newer-generation AH, but only two patients experienced a possibly drug-related serious AE. The occurrence of AEs, drug-related AEs, and treatment discontinuations due to AEs varied between RCTs. Most AEs reported were of mild intensity. Indirect evidence indicates that cetirizine is more sedating than the other newer-generation AHs. CONCLUSION Our findings confirm that newer-generation AHs have a favorable safety and tolerability profile. However, we could not draw firm conclusions regarding the comparative safety profile of the newer-generation AHs due to the paucity of head-to-head RCTs, variation in definitions and reporting of AEs, and short follow-up duration.

Abstract
BACKGROUND Inconsistencies remain regarding the effectiveness and safety of leukotriene receptor antagonists (LTRAs) and selective H1-antihistamines (SAHs) for allergic rhinitis (AR). A meta-analysis of randomized controlled trials (RCTs) was conducted to compare the medications. METHODS Relevant head-to-head comparative RCTs were retrieved by searching the PubMed, Embase, and Cochrane's Library databases from inception to April 20, 2020. A random-effects model was applied to pool the results. Subgroup analyses were performed for seasonal and perennial AR. RESULTS Fourteen RCTs comprising 4458 patients were included. LTRAs were inferior to SAHs in terms of the daytime nasal symptoms score (mean difference [MD]: 0.05, 95% confidence interval [CI] 0.02 to 0.08, p = 0.003, I2 = 89%) and daytime eye symptoms score (MD: 0.05, 95% CI 0.01 to 0.08, p = 0.009, I2 = 89%), but were superior in terms of the nighttime symptoms score (MD: - 0.04, 95% CI - 0.06 to - 0.02, p < 0.001, I2 = 85%). The effects of the two treatments on the composite symptom score (MD: 0.02, 95% CI - 0.02 to 0.05, p = 0.30, I2 = 91%) and rhinoconjunctivitis quality-of-life questionnaire (RQLQ) (MD: 0.01, 95% CI - 0.05 to 0.07, p = 0.71, I2 = 99%) were similar. Incidences of adverse events were comparable (odds ratio [OR]: 0.97, 95% CI 0.75 to 1.25, p = 0.98, I2 = 0%). These results were mainly obtained from studies on seasonal AR. No significant publication bias was detected. CONCLUSIONS Although both treatments are safe and effective in improving the quality of life (QoL) in AR patients, LTRAs are more effective in improving nighttime symptoms but less effective in improving daytime nasal symptoms compared to SAHs.

Abstract
BACKGROUND The clinical benefit of newer antihistamines (AHs) versus other active treatments has not been assessed in pediatric patients with allergic rhinitis. METHODS A systematic literature search was performed in MEDLINE, SCOPUS, and the Cochrane Central Register of Controlled Trials from inception through August 2020. Randomized controlled trials (RCTs) comparing newer with older AHs, corticosteroids, or montelukast were included. The Cochrane Risk of Bias Tool was used for quality assessment. RESULTS Out of 10,656 citations, 16 RCTs (N = 1653) with a duration from 10 days to 3 months were included. When compared with older-generation AHs, the administration of newer AHs did not confer significant benefit and appeared less effective compared with intranasal corticosteroids. However, newer AHs were more potent in achieving symptom control compared with montelukast. Data regarding quality of life were generally missing. The incidence of adverse events was low in all treatment groups. The included RCTs were characterized by moderate risk of bias. CONCLUSIONS Newer AHs are effective in symptom control and well tolerated in the pediatric population. However, inadequate reporting, variation in outcome measures, and a paucity of sufficient randomized comparisons precluded us from quantifying the relative efficacy of newer AHs compared with other treatment options.

Abstract
BACKGROUND Allergic eye diseases are common and cause significant morbidity. Leukotrienes are implicated in the pathogenesis of seasonal and perennial allergic conjunctivitis (AC), commonly seen in conjunction with allergic rhinitis, and in vernal keratoconjunctivitis and atopic keratoconjunctivitis. OBJECTIVES To assess the available evidence for an effect of leukotriene receptor antagonists (LTRAs) on the ocular symptoms of allergic eye diseases. METHODS Selected studies, identified with systematic review search methods, were single/double-blind, randomized, controlled trials that compared LTRAs with other common treatments. RESULTS Eighteen trials, using the LTRA montelukast (in AC only), were identified. Six studies were suitable for meta-analysis, in patients with seasonal AC [treated over a 2-week period, symptoms scored 0 (mild) to 3 (severe)]. These trials were at low risk of bias without significant heterogeneity. Six trials were analyzed and showed that montelukast improved patients' ocular symptoms to a greater extent than placebo, with a difference in mean change-from-baseline score of -0.10 (95% CI, -0.14 to -0.07; P < .00001). Three trials compared montelukast with oral antihistamine. The difference in mean change-from-baseline score was 0.08 (95% CI, 0.02 to 0.14; P = .007), in favor of antihistamines. Two trials compared montelukast and oral antihistamine with placebo. The difference in mean change-from-baseline score was -0.30 (95% CI, -0.38 to -0.21; P < .00001), in favor of combination treatment. CONCLUSIONS In seasonal AC LTRAs are more efficacious than placebo but less efficacious than oral antihistamines in adult patients. Clinical trials should be conducted to determine whether combination treatment with LTRA and oral antihistamine has a synergistic effect. Further research is required to clarify the role of LTRAs in other allergic eye diseases.

Abstract
OBJECTIVE This study was designed to assess the hypothesis that leukotriene receptor antagonists (LTRAs) would provide additional symptom relief in asthmatic children with persistent AR already taking regular antihistamine. The effects of 16-week treatment of LTRA in addition to fexofenadine (FEX) on persistent AR in asthmatic children were examined. STUDY DESIGN Consecutive children with stable asthma and persistent AR were invited in this randomized, double-blind, placebo-controlled study. After a 2-week run-in period in which subjects were given FEX alone, they were randomly assigned to take LTRA or placebo in addition to FEX for 16 weeks, followed by 8 weeks of follow-up phase with FEX taken alone. Symptom scoring, rhinoscopy, acoustic rhinometry, spirometry, nasal secretion extraction and blood taking for IL-4 and IL-13 analysis were performed after a 2-week run-in and at the end of treatment. RESULTS Forty-four subjects with a median (IQR) age of 12.2 (10.1-14.1) years were recruited. At week 4 of treatment, the between-group differences in the mean changes of daytime sneezing score (mean difference (95% CI) = -0.35 (-0.59, -0.12), P = 0.004), nighttime sneezing score (mean difference (95% CI) = -0.37 (-0.62, -0.11), P = 0.007) and daytime composite score (mean difference (95% CI) = -1.08 (-1.92, -0.25), P = 0.013) were significant. Acoustic rhinometry also demonstrated a nearly significant difference in nasal volume change between groups at 16 weeks of treatment (mean difference (95% CI) = 0.572 (0.090-1.054), P = 0.021). IL-4 and IL-13 were not detected in the majority of nasal secretion or serum samples. CONCLUSIONS Additional LTRA provided a more rapid relief on sneezing at the 4-week time point. This combination therapy also maintained a greater nasal volume and this might translate to lesser nasal congestion.

Abstract
Cetirizine (Zyrtec) is a potent and long-acting second-generation histamine H1- receptor antagonist for the treatment of allergic disease, such as allergic rhinitis and chronic idiopathic urticaria, in adult and child. It is a racemic mixture of levocetirizine (Xyzal) and dextrocetirizine. The purpose of this present study was to compare the efficacy of cetirizine, levocetirizine and placebo for the treatment of pediatric perennial allergic rhinitis. 74 perennial allergic rhinitis patients, aged 6 to 12 years old, assigned to 1 of 3 treatment groups for 12 weeks randomly. The effects of the three agents were compared with the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) and Total Symptom Score (TSS) by diary. Nasal peak expiratory flow rate (nPEFR) and laboratory examinations including serum immunoglobulin E level, eosinophil cationic protein (ECP), blood eosinophil counts and eosinophil percentage in a nasal smear were evaluated among the three groups. The results revealed that both cetirizine and levocetirizine improved TSS in comparison with the placebo group, and ceterizine appeared to be more efficacious than levocetirizine at week 8 and week 12. The PRQLQ score showed significant decreased both in cetirizine and levocetirizine group, but there was no statistic significant difference between both groups. The eosinophil proportion in a nasal smear significantly decreased among the cetirizine in comparison with the placebo group but there was no statistic significant in levocetirizine groups. Both cetirizine and levocetirizine showed significant improvement in nPEFR in comparison with the placebo group, and ceterizine appeared to be more efficacious than levocetirizine. The 12-week treatment program showed that cetirizine was more effectious than levocetirizine.

Abstract
Mast cells are key components of the immune system, where they help orchestrate the inflammatory response. Aberrant mast cell activation is linked to a variety of allergic diseases, including asthma, eczema, rhinitis, and nasal polyposis, which in combination affect up to 20% of the population in industrialized countries. On activation, mast cells release a variety of signals that target the bronchi and vasculature and recruit other immune cells to the inflammatory site. Prominent among such signals are the cysteinyl leukotrienes, a family of potent proinflammatory lipid mediators comprising leukotriene C(4) (LTC(4)), LTD(4), and LTE(4). LTC(4), the parent compound, is secreted from mast cells following Ca(2+) influx through store-operated calcium release-activated calcium (CRAC) channels. Here, we show that activated mast cells release a paracrine signal that evokes Ca(2+) signals in spatially separate resting mast cells. The paracrine signal was identified as a cysteinyl leukotriene because 1) RNAi knockdown or pharmacological block of the 5-lipoxygenase enzyme prevented activated mast cells from stimulating resting cells. 2) Block of cysteinyl leukotriene type I receptors on resting mast cells with the clinically prescribed receptor antagonist montelukast prevented their activation by active mast cells. 3) RNAi knockdown of cysteinyl leukotriene type I receptors on resting cells prevented them from responding to the paracrine signal derived from activated mast cells. 4) Purified LTC(4) evoked Ca(2+) signals in mast cells that were identical to those triggered by the paracrine signal. Low levels of stimulus intensity released sufficient levels of leukotriene to activate resting cells. Leukotriene secretion still occurred tens of minutes after stimulation, suggesting a role as a long-lasting trigger in mast cell activation. Stimulation of the cysteinyl leukotriene receptor activated CRAC channels and evoked prominent store-operated Ca(2+) entry. This resulted in further cysteinyl leukotriene production, triggering a positive feedback cascade. Acutely isolated mast cells from patients with allergic rhinitis exhibited store-operated Ca(2+) influx through CRAC channels and responded to cysteinyl leukotrienes. Histological analysis of samples taken from patients revealed clustering of mast cells, often located within 20 microm of each other, a distance sufficient for paracrine signaling by leukotrienes to operate effectively. We conclude that a positive-feedback cascade involving CRAC channels and cysteinyl leukotrienes constitute a novel mechanism for sustaining mast cell activation.

Cysteinyl-leukotrienes (CysLTs) are endogenous mediators of inflammation and play an important role in allergic airway disease by stimulating bronchoconstriction, mucus production, mucosal oedema and inflammation, airway infiltration by eosinophils, and dendritic cell maturation that prepares for future allergic response. Montelukast inhibits these actions by blocking type 1 CysLT receptors found on immunocytes, smooth muscle and endothelium in the respiratory mucosa. Initially developed as a treatment for asthma, montelukast has more recently found use in the treatment of allergic rhinitis (AR). We conducted a systematic review of studies that have evaluated montelukast in the treatment of seasonal AR (SAR) and perennial AR (PAR), with and without concomitant asthma. Primary consideration was given to large, randomised, placebo-controlled, double-blind clinical trials in which AR endpoints were assessed and the use of concurrent treatments for AR was excluded. Eight such studies were found in the literature. The primary endpoint in these was daytime nasal symptom severity represented by a composite score derived from individual self-ratings of nasal congestion, rhinorrhoea, nasal pruritus and sneezing. Secondary endpoints have included these individual nasal symptom scores, additional scores for eye, ear and throat symptoms, the impact of rhinitis on quality of sleep, global evaluations of outcome by patients and physicians, and measures of the severity of concomitant asthma. A general outcome was that patients treated with montelukast had significantly greater improvements in their symptoms of SAR and PAR than did patients who were given a placebo. As monotherapy, montelukast exhibited efficacy similar to that of loratadine, but less than that of the intranasally administered corticosteroid fluticasone propionate. The use of montelukast in combination with antihistamines such as loratadine or cetirizine has generally resulted in greater efficacy than when these agents were used alone, and in some studies has produced results comparable with intranasally applied corticosteroids. In patients with AR comorbid with asthma, montelukast treatment has resulted in significant improvements in both, compared with placebo. Montelukast is well tolerated and has a favourable safety profile; adverse events have occurred at similar frequencies in patients taking either montelukast or placebo. Montelukast provides an effective and well tolerated oral treatment for allergic airway inflammation in patients with SAR or PAR without asthma, and in patients in whom AR is comorbid with asthma.

Abstract
PURPOSE OF REVIEW The goal of treatment of allergic rhinitis should include improvement of daytime and nighttime symptoms, sleep, and quality of life. Congestion from allergic rhinitis is associated with decreased learning and productivity at work and school and a reduced quality of life. The release of inflammatory mediators and activation of inflammatory cells results in nasal congestion, causing disrupted sleep and subsequent daytime somnolence. RECENT FINDINGS This review presents evidence that allergic rhinitis causes sleep disruption, and discusses the pathophysiology of this process. The medications used to treat allergic rhinitis and their ability to improve sleep in patients with allergic rhinitis are reviewed. SUMMARY Some allergic rhinitis medications can be sedating; therefore, it is important to treat allergic rhinitis with medications that improve symptoms while producing few adverse effects. Medications such as the second-generation antihistamines and anticholinergic drugs are well tolerated, but have little effect on congestion. Intranasal corticosteroids reduce congestion, improve sleep and sleep problems, and reduce daytime sleepiness, fatigue, and inflammation. Recently, montelukast, a leukotriene receptor antagonist, has been added to the therapies approved for allergic rhinitis. Montelukast significantly improves both daytime and nighttime symptoms.

Abstract
Cysteinyl leukotrienes (CysLTs) are a family of inflammatory lipid mediators synthesized from arachidonic acid by a variety of cells, including mast cells, eosinophils, basophils, and macrophages. This article reviews the data for the role of CysLTs as multi-functional mediators in allergic rhinitis (AR). We review the evidence that: (1) CysLTs are released from inflammatory cells that participate in AR, (2) receptors for CysLTs are located in nasal tissue, (3) CysLTs are increased in patients with AR and are released following allergen exposure, (4) administration of CysLTs reproduces the symptoms of AR, (5) CysLTs play roles in the maturation, as well as tissue recruitment, of inflammatory cells, and (6) a complex inter-regulation between CysLTs and a variety of other inflammatory mediators exists.

Abstract
Leukotriene receptor antagonists (LTRAs) were recently added to the method of treating allergic rhinitis (AR). However, in children under 6 yr old, there has been no study about its efficacy in treating AR. We aim to compare the clinical efficacy of montelukast, cetirizine and placebo in the treatment of children from 2 to 6 yr old with perennial allergic rhinitis (PAR), to see if there are any significant differences. Sixty children were selected and treated with montelukast, or cetirizine, or placebo once daily. The efficacy of the three agents was compared with the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) and Total Symptom Score (TSS) by diary. In addition, we also examined serum IgE, serum eosinophil cationic protein (ECP), blood eosinophil counts, nasal airway resistance (NAR) and eosinophil percentage in nasal smears. The results revealed that both montelukast and cetirizine were significantly efficacious compared with placebo in NAR, eosinophil percentage in nasal smears, PRQLQ, TSS and all symptom items except nasal itching, throat itching and tearing. For nasal itching, only cetirizine was significantly efficacious. On the other hand, for night sleep quality, montelukast was significantly superior to cetirizine.

Abstract
BACKGROUND Perennial allergic rhinitis (PAR) is a persistent allergic inflammation of the upper respiratory tract due to year-round allergen exposure. OBJECTIVE To evaluate the leukotriene receptor antagonist montelukast for the treatment of PAR. METHODS Protocol 265 was a 2-arm study performed during the winter. After a placebo run-in period, adults with perennial allergen sensitivity and active symptoms of PAR were randomized to receive 10 mg of montelukast (n=1002) or placebo (n=990) once daily during a 6-week, double-blind, active-treatment period. The primary end point was the daytime nasal symptoms score, defined as the average of scores for nasal congestion, rhinorrhea, and sneezing rated daily by patients. RESULTS Statistically significant improvements in PAR symptoms were seen in patients treated with montelukast. Their daytime nasal symptoms scores were reduced during treatment compared with those of the placebo group: the difference between treatments in least squares mean change from baseline was -0.08 (95% confidence interval [CI], -0.12 to -0.04; P < .001). Montelukast treatment also improved global evaluations of allergic rhinitis by patients and Rhinoconjunctivitis Quality of Life Questionnaire scores: differences vs the placebo group were -0.15 (95% CI, -0.27 to -0.04; P < .01) and -0.15 (95% CI, -0.24 to -0.06; P < .001), respectively. Other end points that showed statistically significant improvement with montelukast treatment were nighttime symptoms and each of the 4 nasal symptoms (congestion, rhinorrhea, sneezing, and itching). The treatment effects of montelukast were stable and persistent during the entire 6 weeks of treatment. CONCLUSION Montelukast provided statistically significant relief of PAR symptoms during 6 weeks of treatment.
