Abstract
The Saudi Initiative for Asthma 2024 (SINA-2024) is the sixth version of asthma guidelines for the diagnosis and management of asthma for adults and children that was developed by the SINA group, a subsidiary of the Saudi Thoracic Society. The main objective of the SINA is to have guidelines that are up-to-date, simple to understand, and easy to use by healthcare workers dealing with asthma patients. To facilitate achieving the goals of asthma management, the SINA Panel approach is mainly based on the assessment of symptom control and risk for both adults and children. The approach to asthma management is aligned for age groups: adults, adolescents, children aged 5-12 years, and children aged <5 years. SINA guidelines have focused more on personalized approaches reflecting a better understanding of disease heterogeneity with the integration of recommendations related to biologic agents, evidence-based updates on treatment, and the role of immunotherapy in management. The medication appendix has also been updated with the addition of recent evidence, new indications for existing medication, and new medications. The guidelines are constructed based on the available evidence, local literature, and the current situation at national and regional levels. There is also an emphasis on patient-doctor partnership in the management that also includes a self-management plan.

Chryseriol attenuates the progression of OVA-induced asthma in mice through NF-κB/HIF-1α and MAPK/STAT1 pathways. Allergol Immunopathol (Madr) 2023; 51:146-153. [PMID: 36617834 DOI: 10.15586/aei.v51i1.776] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Accepted: 10/18/2022] [Indexed: 01/03/2023]
Abstract
BACKGROUND Asthma is a hackneyed chronic inflammatory disease of the airway. Chryseriol (CSR) is a kind of flavonoid, and has the effect of bronchiectasis, indicating its potential application for treating respiratory diseases. However, the functions of CSR in asthma have not been reported till now. MATERIALS AND METHODS The histopathologic changes of the lung tissues were assessed by hematoxylin and eosin staining. The cell apoptosis was identified through terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling assay. Total numbers of eosinophils, neutrophils, and macrophages were assessed under microscope. The levels of interleukin (IL)-1β, IL-4, IL-5, and IL-13 were detected by enzyme-linked-immunosorbent serologic assay. The airway hyper-responsiveness (AHR) was evaluated by the whole body plethysmography. The levels of methane dicarboxylic aldehyde, superoxide dismutase, glutathione S-transferase, and glutathione in lung homogenates were confirmed by using corresponding commercial kits. The protein expressions were examined by Western blot analysis. RESULTS The ovalbumin (OVA) was utilized to establish asthma mouse model. At first, it was revealed that CSR treatment reduced lung injury in OVA-stimulated mice. Moreover, cell apoptosis was enhanced after OVA stimulation but was attenuated by CSR treatment. In addition, CSR treatment decreased the infiltration of inflammatory cells and the production of inflammatory factors in OVA-treated mice. Further investigations demonstrated that CSR treatment relieved AHR in OVA-stimulated mice. The oxidative stress was strengthened in OVA-treated mice, but these effects were relieved by CSR treatment. Lastly, it was discovered that CSR treatment retarded nuclear factor kappa B (NF-κB)/hypoxia-inducible factor 1 alpha (HIF-1α) and p38 mitogen-activated protein kinase (MAPK)/signal transducer and activator of transcription 1 (STAT1) pathways in OVA-triggered asthma mice. CONCLUSION Our findings proved that CSR attenuated the progression of OVA-induced asthma in mice through inhibiting NF-κB/HIF-1α and MAPK/STAT1 pathways. This work might highlight the functions of CSR in the treatment of asthma.

Abstract
Subcutaneous immunotherapy is recognized as a cornerstone in the management of allergic respiratory disease in patients who are properly characterized with allergy and with allergic rhinoconjunctivis and/or well-controlled asthma, and who are willing to adhere to the rigorous treatment program. A key tenet is that it affords the opportunity to effect long-term clinical remission through its disease-modifying properties. Furthermore, it has the potential to prevent the progression of allergic rhinitis to asthma, prevent new allergen sensitivities, and improve a patient's quality of life.

Abstract
Acute respiratory virus infections, such as influenza and RSV, are predominant causes of asthma exacerbations. Eosinophils act as a double-edged sword in exacerbations in that they are activated by viral infections but also can capture and inactivate respiratory viruses. Phosphodiesterase type 4 (PDE4) is abundantly expressed by eosinophils and has been implicated in their activation. This exploratory study aims to determine whether these opposing roles of eosinophils activation of eosinophils upon interaction with virus can be modulated by selective PDE4 inhibitors and whether eosinophils from healthy, moderate and severe asthmatic subjects respond differently. Eosinophils were purified by negative selection from blood and subsequently exposed to RSV or influenza. Prior to exposure to virus, eosinophils were treated with vehicle or selective PDE4 inhibitors CHF6001 and GSK256066. After 18 hours of exposure, influenza, but not RSV, increased CD69 and CD63 expression by eosinophils from each group, which were inhibited by PDE4 inhibitors. ECP release, although not stimulated by virus, was also attenuated by PDE4 inhibitors. Eosinophils showed an increased Nox2 activity upon virus exposure, which was less pronounced in eosinophils derived from mild and severe asthmatics and was counteracted by PDE4 inhibitors. PDE4 inhibitors had no effect on binding of virus by eosinophils from each group. Our data indicate that PDE4 inhibitors can attenuate eosinophil activation, without affecting virus binding. By attenuating virus-induced responses, PDE4 inhibitors may mitigate virus-induced asthma exacerbations.

Heller MK, Chapman SCE, Horne R. Beliefs about medication predict the misattribution of a common symptom as a medication side effect--Evidence from an analogue online study. J Psychosom Res 2015; 79:519-29.

Abstract
OBJECTIVE Some perceived medication side effects may be 'normal' symptoms that patients misattribute to the medication. Using an analogue approach, we tested if medication beliefs predict whether participants misattribute a headache as a side effect and subsequently intend to stop medication. METHODS We recruited 690 participants, 223 reporting a past asthma diagnosis. They received information about asthma and Molair, a fictitious asthma treatment modeled on a licensed treatment (montelukast). We varied the description of efficacy and side effects (which did not include headache). Pre-exposure to this information, participants completed the Beliefs about Medicine Questionnaire (BMQ)-General and the Perceived Sensitivity to Medicines Scale (PSM), post-exposure they completed the BMQ-Specific. Participants were asked to imagine they experienced a headache while taking Molair. Finally, they rated whether the headache was a side effect (misattribution) and if they would stop taking Molair (behavioral intention). RESULTS Nearly a quarter (170) of participants misattributed the headache to Molair and 69 (10%) subsequently intended to stop Molair. Both outcomes were predicted by general and specific medication beliefs. Odds of misattribution (m) and behavioral intention (i) increased with higher General Harm (ORm=1.90, ORi=2.72), General Overuse (ORm=1.74, ORi=1.56) and Molair Concern beliefs (ORm=1.52, ORi=1.78, all p<.01), but decreased with General Benefit (ORm=0.72, ORi=0.53) and Molair Necessity beliefs (ORm=0.72, ORi=0.70, all p<.05). CONCLUSION Symptom misattribution and subsequent intentions to stop Molair were predicted by pre-exposure beliefs about medicines in general and post-exposure beliefs about Molair. Patients with negative medication beliefs may be prone to misattribute symptoms and subsequently stop medication.

Cysteinyl leukotriene receptor-1 antagonists as modulators of innate immune cell function. J Immunol Res 2014; 2014:608930. [PMID: 24971371 PMCID: PMC4058211 DOI: 10.1155/2014/608930] [Citation(s) in RCA: 74] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2014] [Revised: 05/09/2014] [Accepted: 05/12/2014] [Indexed: 12/20/2022] Open
Abstract
Cysteinyl leukotrienes (cysLTs) are produced predominantly by cells of the innate immune system, especially basophils, eosinophils, mast cells, and monocytes/macrophages. Notwithstanding potent bronchoconstrictor activity, cysLTs are also proinflammatory consequent to their autocrine and paracrine interactions with G-protein-coupled receptors expressed not only on the aforementioned cell types, but also on Th2 lymphocytes, as well as structural cells, and to a lesser extent neutrophils and CD8+ cells. Recognition of the involvement of cysLTs in the immunopathogenesis of various types of acute and chronic inflammatory disorders, especially bronchial asthma, prompted the development of selective cysLT receptor-1 (cysLTR1) antagonists, specifically montelukast, pranlukast, and zafirlukast. More recently these agents have also been reported to possess secondary anti-inflammatory activities, distinct from cysLTR1 antagonism, which appear to be particularly effective in targeting neutrophils and monocytes/macrophages. Underlying mechanisms include interference with cyclic nucleotide phosphodiesterases, 5′-lipoxygenase, and the proinflammatory transcription factor, nuclear factor kappa B. These and other secondary anti-inflammatory mechanisms of the commonly used cysLTR1 antagonists are the major focus of the current review, which also includes a comparison of the anti-inflammatory effects of montelukast, pranlukast, and zafirlukast on human neutrophils in vitro, as well as an overview of both the current clinical applications of these agents and potential future applications based on preclinical and early clinical studies.

Abstract
The aim of this review is to report the updates in the medical literature on the outcomes associated with inhaled corticosteroid use. This update finds that inhaled corticosteroids remain a frontline choice as controller therapy in the treatment of asthma. Adherence to medications, especially inhaled corticosteroids used as controller medications, is responsible for a decrease in hospital, emergency room and physician visits. All of these translate to reduced asthma-related healthcare costs and an increase in health-related quality of life. There is a need for further research on the role of inhaled corticosteroids in chronic obstructive pulmonary disease outcomes.

Abstract
BACKGROUND The inhibitory effect of corticosteroids (CS) on the secretions of cysteinyl-leukotrienes (Cys-LTs) in asthma is controversial. The aim of this study was to evaluate the effect of CS on allergen-induced increase in urinary leukotriene E4 (uLTE4) during early (EAR) and late (LAR) asthmatic responses in mild untreated asthmatics. MATERIAL AND METHODS Nine subjects with mild untreated allergic asthma performed two allergen challenges, after 1-week treatment with beclomethasone dipropionate (BDP, 500 microg b.i.d) or placebo. Forced Expiratory Volume in one second 1 (FEV1) was monitored to assess EAR and LAR, and uLTE4 was measured before and during EAR and LAR. RESULTS After placebo, uLTE4 increased significantly during EAR, but not during and after LAR, in comparison with baseline values. Beclomethasone dipropionate induced a significant attenuation of the uLTE4 increase during EAR, in comparison with placebo, in association with a good protection of LAR (P = 0.002) and a mild protection of EAR (P = 0.07). CONCLUSIONS Beclomethasone dipropionate blunts the early increase in uLTE4 excretion due to allergen challenge, in association with a significant effect on the severity of LAR. These data support the hypothesis that inhaled CS may inhibit the allergen-induced release of cys-LTs in asthma.

Abstract
PURPOSE OF REVIEW There are different phenotypes of asthma, with phenotype-specific differences in medication response observed. RECENT FINDINGS Tobacco smoke exposure reduces corticosteroid responsiveness. Treatment for tobacco smoke-triggered asthma must start with treatment of tobacco dependence. Obesity-associated asthma responds to weight loss and treatment of comorbidities. Immunotherapy and omalizumab are specific therapies for atopic asthma, though its use is limited by expense, inconvenience, need for injections, and toxicities. Leukotriene modifier response is more prominent in viral-triggered asthma. Research on intermittent escalation of controller therapy for asthma shows best results when escalation is substantial and early. Inhaled corticosteroid medications in low-to-moderate doses remain the most important maintenance medication for a broad variety of asthma phenotypes, reducing both impairment and risk. When impairment is not fully controlled by an inhaled corticosteroid, combination with a long-acting beta-agonist, leukotriene modifier, or theophylline can be effective. Inhaled corticosteroid use in children does not appear to influence airway caliber or asthma severity after the medication is stopped. SUMMARY Optimizing maintenance therapy for asthma is not one size fits all. It is important to assess the asthma phenotype in addition to the symptom pattern, in determining optimal maintenance therapy.

Abstract
The Saudi Initiative for Asthma (SINA) provides up-to-date guidelines for healthcare workers managing patients with asthma. SINA was developed by a panel of Saudi experts with respectable academic backgrounds and long-standing experience in the field. SINA is founded on the latest available evidence, local literature, and knowledge of the current setting in Saudi Arabia. Emphasis is placed on understanding the epidemiology, pathophysiology, medications, and clinical presentation. SINA elaborates on the development of patient-doctor partnership, self-management, and control of precipitating factors. Approaches to asthma treatment in SINA are based on disease control by the utilization of Asthma Control Test for the initiation and adjustment of asthma treatment. This guideline is established for the treatment of asthma in both children and adults, with special attention to children 5 years and younger. It is expected that the implementation of these guidelines for treating asthma will lead to better asthma control and decrease patient utilization of the health care system.

Abstract
BACKGROUND Immunomodulatory therapy has been recently introduced for the management of asthma. Suplatast tosilate (ST), a new immune-modifying drug, is known to improve the airway function by inhibiting the release of Th-2 cytokines. However, its efficacy as a controller listed in the guideline, Global Initiative for Asthma 2005 has not been established. In this study we investigated the role of ST in leukotriene receptor antagonist (LTRA) non-responders with mild-to-moderate persistent asthma before initiating corticosteroids inhalation therapy. METHODS This was a prospective open-level clinical trial. LTRAs was given to 41 patients with asthma for 4 weeks and clinical efficacy was assessed using daily symptom scores. The 10 patients, aged 2.5-8.5 years, who failed to show clinical improvement, were defined as LTRA non-responders. After a 1-week washout period, the efficacy of ST was investigated and compared with LTRA non-responders for the following 4 weeks. RESULTS LTRA non-responders showed a significant improvement in the average symptom score, peak expiratory flow, use of rescue medication and the proportion of symptom-free days with ST therapy. CONCLUSIONS ST is a good choice for patients who have failed to respond to LTRAs. ST should therefore be added to the list of treatment options for such patients.

Abstract
PURPOSE To increase awareness among nurse practitioners (NPs) regarding diagnostic and treatment guidelines for asthma for the 5-11 year age group recently updated by the National Asthma Education Prevention Program-Expert Panel 3 (NAEPP-EPR3). DATA SOURCES NAEPP-EPR3 guidelines for the diagnosis and management of asthma released from the National Heart, Lung, and Blood Institute in August 2007, selected clinical trials, meta-analyses, and clinical reviews. CONCLUSIONS Recent research has revealed that children suffering from asthma in the United States are underdiagnosed and their asthma is poorly controlled. Compelling evidence supports that children classified as having persistent asthma following NAEPP-EPR3 guidelines benefit from daily inhaled corticosteroid therapy, yet many are misclassified and undertreated. IMPLICATIONS FOR PRACTICE With application of current guidelines from NAEPP-EPR3, NPs can more effectively assess, diagnose, treat, and foster a collaborative self-management plan for children age 5-11 years. These interventions will result in an improved quality of life and decreased health risks for this young population.

Fluticasone or montelukast for preschool children with asthma-like symptoms: Randomized controlled trial. Pulm Pharmacol Ther 2008; 21:798-804.

Abstract
RATIONALE Beneficial effects of anti-inflammatory therapy such as fluticasone propionate (FP) and montelukast (Mk) have been demonstrated in preschool children with asthma. However, comparative studies are lacking in this age group. Therefore, we conducted a study to evaluate and compare the effect of FP and Mk in preschool children with asthma-like symptoms. METHODS In this multicenter, randomized, placebo-controlled, double-blind, double-dummy trial, children aged 2-6 years with asthma-like symptoms were included. In total, 63 children were randomly allocated to receive FP (25), Mk (18) or placebo (20) for 3 months. The primary outcome was the daily symptom score (wheeze, cough, shortness of breath) as recorded by caregivers in a symptom diary card. Secondary endpoints were rescue medication free days, blood eosinophils and lung function (interrupter technique and forced oscillation technique (FOT)). RESULTS During the 3 months study period, symptoms improved in all 3 groups, with a statistically significant difference between FP and placebo in favor of the FP group (p=0.021). A significant reduction in circulating eosinophils after 3 months of treatment was found in the Mk group only (p=0.008), which was significantly different from the change found in the placebo group (p=0.045). With the exception of frequency dependence (measured by FOT), which showed a difference between FP and Mk after 3 months of treatment in favor of the FP group (p=0.048), no differences in lung function within or between groups were found. CONCLUSIONS In spite of a lack of power, our results suggest that FP has a beneficial effect on symptoms and Mk on blood eosinophil level as compared to placebo. Except for a difference in one lung function parameter after 3 months between FP and Mk in favor of the FP group, this study revealed no differences between FP and Mk.

Abstract
BACKGROUND Leukotriene synthesis inhibitors and receptor antagonists are efficacious for the treatment of asthma. Diets containing the fatty acids gammalinolenic acid (GLA) and eicosapentaenoic acid (EPA) decrease leukotriene synthesis; however, their impact on asthma management and quality of life (QOL) has not been evaluated in asthmatic subjects. OBJECTIVE To evaluate asthma management and the QOL of asthmatic adult subjects consuming a medical food emulsion containing GLA and EPA. RESEARCH DESIGN AND METHODS Trial 1 was a randomized, prospective, double-blind, placebo-controlled, parallel group trial in atopic subjects with mild-to-moderate asthma (n = 35 evaluable) consuming a low dose (0.75 g GLA + 0.5 g EPA), high dose (1.13 g GLA + 0.75 g EPA) or placebo emulsion daily. Subjects were questioned about their asthma management using a non-validated questionnaire after 2 and 4 weeks. Blood leukotrienes were measured at baseline and after 4 weeks. Trial 2 was an open-label study (n = 65 evaluable) where subjects consumed the low-dose medical food emulsion, EFF1009, daily. QOL and asthma management were measured using the validated Mini Asthma Quality of Life (MiniAQLQ) and the Asthma Control (ACQ) questionnaires, respectively, administered at baseline and after 4 weeks. RESULTS In Trial 1, leukotriene biosynthesis decreased (p < 0.05). Self-reported asthma status and bronchodilator use improved in subjects consuming low- and high-dose emulsion between week 2 and week 4 (p < 0.01), but not compared to placebo (p > 0.1). In Trial 2, mean +/- standard error total MiniAQLQ and ACQ scores improved by 1.5 +/- 0.2 and 1.0 +/- 0.1, respectively (p < 0.001). Subdomain scores from MiniAQLQ improved and rescue bronchodilator use decreased (p < 0.001). CONCLUSION The inclusion of the medical food EFF1009 in asthma management regimens can improve patient quality of life and decrease reliance on rescue medication.

Abstract
Inhaled corticosteroids, long-acting beta2-adrenoceptor agonists, and leukotriene receptor antagonists are widely used for treatment of asthma. Inhaled corticosteroids are recommended as first-line therapy, whereas long-acting beta2-adrenoceptor agonists and leukotriene receptor antagonists are indicated as add-on therapy in patients not adequately controlled with corticosteroids alone. A number of studies have investigated the efficacy of combinations of these drugs in asthma, but several issues concerning the safety of these treatments are highly debated. This review provides a critical appraisal of the tolerability profiles of long-acting beta2-agonists and leukotriene receptor antagonists used in combination with inhaled corticosteroids for the treatment of asthma.

Abstract
Two obstructive lung diseases, asthma and chronic obstructive pulmonary disease, account for the vast majority of prescriptions for aerosolized medications and devices . Asthma is an immunologically mediated condition characterized by episodic reversible airway obstructions that occur in all age groups. In contrast, chronic obstructive pulmonary disease is a condition characterized by relatively irreversible obstruction that is seen in middle-aged and elderly cigarette smokers. Nevertheless, there is sufficient overlap in terms of airway physiology and therapeutics to allow a review of the challenge of aerosol delivery in both conditions in the same article. This review will concentrate on issues related to aerosol delivery.

Abstract
Chronic inflammation and smooth muscle dysfunction are consistent features of asthma, and are responsible for disease progression and airway remodelling. The development of chronic airway inflammation depends upon the recruitment and activation of inflammatory cells and the subsequent release of inflammatory mediators, including cytokines. Cellular and histological evaluation of drugs with anti-inflammatory activity, such as inhaled corticosteroids (ICSs), is achieved by analysing samples of lung tissue or biological fluids, obtained by techniques such as bronchial biopsy, bronchoalveolar lavage and sputum induction. These provide valuable information on the inflammatory processes occurring in the lung, although not all are equal in value. The beneficial effects of ICSs in asthma treatment are a consequence of their potent and broad anti-inflammatory properties. Furthermore, there have been promising results indicating that ICSs can reverse some of the structural changes that contribute to airway remodelling. Long-acting beta2-agonists (LABAs) added to ICSs provide greater clinical efficacy than ICSs alone, suggesting the possibility of complementary activity on the pathophysiological mechanisms of asthma: inflammation and smooth muscle dysfunction. Leukotrienes play a part in the pathogenesis of asthma. Leukotriene receptor antagonists (LTRAs) directly inhibit bronchoconstriction and may have some anti-inflammatory effects, although the extent to which inhibiting one set of inflammatory mediators attenuates the inflammatory response is questionable. In concert with their effect on a broad variety of inflammatory mediators and cells, treatment with ICSs (including ICSs and LABAs) results in superior control of the pathophysiology of asthma and superior clinical efficacy as assessed by the greater improvements in pulmonary function and overall control of asthma compared with LTRAs.
