Eosinophils and mast cells are among the key cells in inflammatory diseases like chronic rhinosinusitis (CRS) and asthma. Leukotriene antagonists have proven to be effective in the treatment of asthma, but data about their efficacy in CRS are scarce, whereas data on montelukast as an add-on treatment to intranasal corticosteroids (INCS) in a postoperative setting are completely lacking.. Prospective, randomized, open-label trial.. In this trial with long-term follow-up, we evaluated the efficacy of montelukast as an add-on treatment to INCS in postoperative CRS with nasal polyp (CRSwNP) patients. CRSwNP patients (N = 72) undergoing endoscopic sinus surgery were randomized in two arms for the postoperative treatment. One group (N = 36) received INCS in monotherapy, whereas the other group (N = 36) received INCS in association with montelukast for 1 year. The efficacy of montelukast with INCS was evaluated by assessing both subjective (total five-symptom score [T5SS]) and objective (nasal polyp score [NPS], Lund-Mackay [LMK] score, and subjective olfactometry [Barcelona Smell Test 24]) outcome parameters and compared with the gold standard of INCS in monotherapy.. After 1 year of surgery, T5SS, NPS, and LMK score were significantly reduced in patients treated with either INCS or INCS plus montelukast, without significant differences between the two treatment arms. Improvement of smell loss by olfactometry was also observed with no differences between arms. Similar findings were observed at 3 and 6 months.. These results suggest that the addition of montelukast to INCS should not be recommended in the treatment of postoperative CRSwNP patients.. 1b Laryngoscope, 1743-1751, 2018.

Cysteinyl leukotriene (LT) has been proposed in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP). This study sought to examine the expression of the LT receptor (LTR) in CRSwNP patients and evaluate the potential role of LTR antagonist (LTRA) in the management of eosinophilic CRSwNP (ECRS) patients.. Nasal polyps and uncinate process tissues were collected from 18 ECRS patients, 13 non-eosinophilic CRSwNP (non-ECRS) patients, and 16 control subjects. The messenger RNA (mRNA) and protein expression of LTR (cysteinyl leukotriene receptor 1 [CysLT1R] and cysteinyl leukotriene receptor 2 [CysLT2R]) was examined using quantitative reverse-transcription polymerase chain reaction (qRT-PCR), immunohistochemistry, and Western blot analysis. Moreover, the effects of LTRA and steroids on total nasal symptom scores (TNSS) of uncontrolled ECRS patients were evaluated.. The mRNA and protein expression of CysLT1R and CysLT2R was significantly increased in polyp tissues compared with healthy controls (p < 0.05). Compared with the non-ECRS subset, the ECRS subset showed significantly increased expression of CysLT1R and CysLT2R, as well as leukotriene C4 (LTC4) and leukotriene D4 (LTC4) levels (p < 0.05). Moreover, combined LTRA and steroids significantly decreased TNSS more than steroids alone in uncontrolled ECRS patients (p < 0.01).. Our findings indicate that LTR was differentially expressed between ECRS and non-ECRS patients, and that LTRA may be used as an additional therapy for ECRS patients.

Chronic rhinosinusitis associated with asthma is often difficult to treat effectively with intranasal corticosteroids alone. Thus, the aim of this study was to evaluate the effectiveness of combination treatment with an intranasal corticosteroid and a leukotriene-receptor antagonist (montelukast) in reducing the size of nasal polyps.. The subjects of this study were 20 patients with chronic rhinosinusitis associated with adult-onset asthma, which was being treated with inhaled corticosteroids. All patients were treated with intranasal fluticasone propionate, 200 microg/day, and montelukast, 10 mg/day, for 1 year. The size of nasal polyps and the score of sinus shadows were assessed with nasal endoscopy and computed tomography (CT), respectively, before and after treatment. The peripheral blood eosinophil counts were also evaluated before and after treatment.. Nasal polyps were significantly smaller after both 6 months (p<0.01) and 12 months of treatment (p<0.01) than before treatment. The decrease in the shadow score was statistically significant after both 6 months (p<0.01) and 12 months of treatment (p<0.01). Significant reductions in peripheral blood eosinophil counts were also seen after both 6 months (p<0.05) and 12 months of treatment (p<0.01). A significant correlation was found between the rate of change in the peripheral blood eosinophil count and that in the CT score after both 6 months (r=0.578, p=0.012) and 12 months (r=0.625, p=0.007).. Combined treatment with intranasal fluticasone propionate and montelukast, for at least 1 year, is effective for chronic rhinosinusitis associated with adult-onset asthma.

Leukotriene signaling is essential in many diseases, including asthma, allergic rhinitis, atherosclerosis and inflammatory bowel disease. Nevertheless, the expression of cysteinyl leukotrienes (CysLTs) and its receptors (CYSLTRs) in different types of nasal polyps (NPs), and the role of their antagonist in the treatment of refractory chronic rhinosinusitis with nasal polyps (CRSwNP) are not well understood. The following study investigates the expression of CysLTs and CYSLTRs in different types of NPs, as well as the role of leukotriene receptor antagonist (montelukast) in refractory NPs. Our data showed that CysLTs and CYSLTRs were significantly elevated in CRSwNP group (p < 0.05), particularly in IL-5

Montelukast is used in the treatment of allergic rhinitis and asthma. It has been used as adjuvant therapy in patients with chronic rhinosinusitis (CRS), but its effectiveness has not been evaluated. This study evaluates the efficacy of adjuvant leukotriene receptor antagonism in CRS and subtypes.. Retrospective review of collected data at a tertiary-referral institution. We identified all patients who were prescribed montelukast postoperatively and had a lapse in therapy for at least 1 month (n = 50), so that the patients themselves serve as their own control group. Twenty-item Sino-Nasal Outcomes Test (SNOT-20) scores and Lund-Kennedy endoscopy scores were obtained for each patient. Scores were compared with and without montelukast using Wilcoxon signed rank test. The analysis was controlled for changes in other medications.. Fifty-two therapy lapses were identified in 50 patients. Twenty-seven patients had eosinophilic CRS with polyps (eCRSwNP), 8 had Samter's triad (ST), and 15 had allergic fungal sinusitis (AFS). Overall mean follow-up was 46.5 months. Overall, SNOT-20 scores and endoscopy scores were significantly lower with montelukast (p < 0.005 for both). On subgroup analysis, SNOT-20 scores were significantly improved for patients with eCRSwNP and AFS (p < 0.001 and p = 0.001, respectively). Endoscopy scores were significantly improved for patients with eCRSwNP (p = 0.044). Outcomes approached, but did not reach, significance for patients with ST (p = 0.123 for SNOT-20 and p = 0.146 for endoscopy). There was also significant improvements in patients with asthma.. The addition of montelukast as postoperative therapy may be beneficial for patients with eCRSwNP and AFS.

Corticosteroids are agents that suppress the immune system. Their suppressive activity is predominantly restricted to cell-mediated immunity, with a marginal inhibitory effect on humoral immunity.. To describe an acquired reversible B-cell deficiency in a patient treated with low-dose corticosteroids for 36 years.. A broad range of T- and B-cell parameters were studied over time, during and after discontinuation of corticosteroid therapy. Published works on this topic in animal and human models are reviewed. The findings unique to this patient are highlighted.. While undergoing long-term corticosteroid therapy, a patient developed a clinical and immunologic picture suggestive of common variable immunodeficiency, with predominantly qualitative and quantitative B-cell abnormalities. These abnormalities resolved within 2 years after tapering of corticosteroid therapy.. Long-term low-dose corticosteroid use may reversibly decrease B-cell counts and specific antibody responses.

In mice, allergic rhinitis augments the infectious and inflammatory response to Streptococcus pneumoniae-induced sinusitis.. To investigate the effects of cysteinyl leukotriene antagonism on the severity of bacterial infection.. We performed 3 parallel, placebo-controlled experiments. In the first, mice were ovalbumin sensitized and ovalbumin challenged to show the effects of montelukast on the allergic inflammation; in the second, we evaluated the effect of montelukast on S. pneumoniae infection; in the third, we used mice that were both allergic and infected. Montelukast was given starting 2 days after sensitization until the day before euthanasia. One day after drug treatment began, the mice were inoculated intranasally with S. pneumoniae in the infected groups. Nasal hypersensitivity was measured with histamine challenges before the first sensitization and on the day before euthanasia. On the fifth day after infection, mice were euthanized, nasal lavage was performed, bacteria were cultured, and inflammatory cells in the sinuses were quantified.. Mice that were infected only tended toward having increased bacterial counts from nasal lavage in the montelukast-treated group. The mice that were allergic and infected experienced significantly higher bacterial counts (P < .05). All 3 montelukast treatment groups had significantly decreased eosinophil counts as well as T-lymphocyte counts.. Montelukast reduces the manifestations of allergic rhinitis in mice. Surprisingly, montelukast led to an increase in bacterial growth in infected mice. This suggests an effect of the cysteinyl leukotrienes on the innate response to bacterial infection.

Although there is evidence from randomised controlled trials that leukotriene receptor antagonists are efficacious in chronic rhinosinusitis there are still little data on their use in everyday real life clinical practice. We report on a pragmatic case series of 32 patients referred from primary care with uncontrolled chronic rhinosinusitis (allergic or non-allergic) who have been treated with montelukast in our joint medical/surgical rhinology clinic. Patients' symptoms were scored according to "facial pain", "headache", "nasal blockage", "nasal discharge", "sense of smell" and "daily activity", and measurements of peak inspiratory nasal flow were made, before and after the introduction of montelukast 10 mg/day. There were significant (p < 0.05) improvements in subjective scoring for headache, nasal discharge & blockage, sense of smell and daily activity but not for facial pain, when montelukast was added along with other alterations in chronic rhinosinusitis medication (all receiving intra-nasal corticosteroids). Subgroup analysis of 10 patients, were the addition of montelukast was the only change to medical therapy, showed significant (p < 0.05) improvements in headache, nasal discharge and blockage and their daily activity. There was no significant improvements in nasal peak inspiratory flow or spirometry. In conclusion, montelukast may be a useful therapeutic option in addition to standard therapy (i.e. intra-nasal corticosteroids or anti-histamines) when treating patients with chronic rhinosinusitis in a real life clinical setting.
