Objective: The aim of this study was to assess the prevalence of exercise-induced bronchospasm in students of sciences and techniques of physical activities and sports (STAPS) exercising in a hot, humid and relatively polluted environment. Methods: Twenty-two first-year undergraduate students, including 11 in PE and 11 in SPORT, aged 21.64 ± 1.80 years, participated in a football match. Resting spirometry was performed before and 5 minutes after the match. During the match, particulate matter (PM2.5 and PM10) was measured every 10 minutes around the football pitch. Ambient temperature and relative humidity were recorded. The diagnosis of EIB was based on a decrease in FEV1 of at least 10% after the match. If there was a decrease, the participant was considered susceptible to EIB. Results: Five subjects were positive for exercise-induced bronchospasm, a percentage of 22%. Ambient temperature and relative humidity were 34.22˚C ± 1.38˚C and 52.2% ± 4.97%, respectively. Concentrations of PM2.5 and PM10 were between 53.3 - 115.5 µg/m3 and 75.5 - 168.2 µg/m3, respectively, exceeding WHO limits. Conclusion: These results show a high incidence of exercise-induced bronchospasm in students without a history of asthma but exercising in a hot, humid and environment polluted by fine particles.展开更多

文摘The global incidence of asthma,a leading respiratory disorder affecting more than 235 million people,has dramatically increased in recent years.Characterized by chronic airway inflammation and an imbalanced response to airborne irritants,this chronic condition is associated with elevated levels of inflammatory factors and symptoms such as dyspnea,cough,wheezing,and chest tightness.Conventional asthma therapies,such as corticosteroids,long-actingβ-agonists,and antiinflammatory agents,often evoke diverse adverse reactions and fail to reduce symptoms and hospitalization rates over the long term effectively.These limitations have prompted researchers to explore innovative therapeutic strategies,including stem cell-related interventions,offering hope to those afflicted with this incurable disease.In this review,we describe the characteristics of stem cells and critically assess the potential and challenges of stem cell-based therapies to improve disease management and treatment outcomes for asthma and other diseases.
文摘BACKGROUND The relationship between diabetes mellitus(DM)and asthma is complex and can impact disease trajectories.AIM To explore the bidirectional influences between the two conditions on clinical outcomes and disease control.METHODS We systematically reviewed the literature on the relationship between DM and asthma,focusing on their impacts,mechanisms,and therapeutic implications.Various studies were assessed,which investigated the effect of glycemic control on asthma outcomes,lung function,and exacerbations.The study highlighted the role of specific diabetes medications in managing asthma.RESULTS The results showed that poor glycemic control in diabetes can exacerbate asthma,increase hospitalizations,and reduce lung function.Conversely,severe asthma,especially in obese individuals,can complicate diabetes management and make glycemic control more difficult.The diabetes-associated mechanisms,such as inflammation,microangiopathy,and oxidative stress,can exacerbate asthma and decrease lung function.Some diabetes medications exhibit anti-inflammatory effects that show promise in mitigating asthma exacerbations.CONCLUSION The complex interrelationship between diabetes and asthma suggests bidirectional influences that affect disease course and outcomes.Inflammation and microvascular complications associated with diabetes may worsen asthma outcomes,while asthma severity,especially in obese individuals,complicates diabetes control.However,the current research has limitations,and more diverse longitudinal studies are required to establish causal relationships and identify effective treatment strategies for individuals with both conditions.

文摘Bronchial asthma is divided into type 2 and non-type 2 asthma based on the immunopathogenesis.Type 2 inflammation is an inflammation mediated by T helper 2 cells,group 2 innate lymphoid cells and sustained by a specific subset of cytokines.In recent years,type 2 asthma has become the research hotspot in the field of asthma.For type 2 asthma,targeted therapies have become effective treatments and widely used in clinical practice.In order to further understand the progress of biologic drugs for bronchial asthma,as well as the disease outcomes in patients with type 2 asthma,and improve asthma control and remission,this article reviewed the progress and achievements of biologic drugs for asthma from May 1,2023 to April 30,2024,providing clinical perspective for the choosing appropriate targeted treatment of asthma.It also highlights selected poster pre-sentations from the ATS 2024 Annual Meeting to provide clinical insights for choosing appropriate targeted treatments for Type 2 asthma.
文摘BACKGROUND Diffuse panbronchiolitis(DPB)is a rare,chronic inflammatory lung disease mar-ked by chronic cough,breathlessness,and preceding sinusitis.Symptoms often persist for years and can be misdiagnosed as asthma,particularly in children.This report describes a DPB case resolved with long-term azithromycin therapy,em-phasizing the need for a timely and accurate diagnosis.CASE SUMMARY A 12-year-old girl,diagnosed with asthma at age five and managed with inhaled corticosteroids and long-acting beta-2 agonists,developed a history of chronic productive cough and chronic sinusitis for a year.On examination,she exhibited wheezing and coarse crackles.Despite receiving treatment for an asthma exacer-bation,her symptoms did not improve.A chest X-ray revealed reticulonodular infiltration in both lower lungs,prompting further evaluation with high-resolu-tion computed tomography(HRCT).The HRCT confirmed centrilobular nodule opacities,a'tree-in-bud'pattern,and non-tapering bronchi,suggesting DPB.Elevated cold hemagglutinin titers at 128 further supported the diagnosis.Her cough and sinusitis resolved within a month after starting azithromycin therapy,chosen for its anti-inflammatory and immunomodulatory effects.Follow-up HRCT scans after 1 year of continuous treatment showed complete normalization.CONCLUSION This case highlights the importance of early diagnosis and prompt treatment in achieving favorable outcomes for DPB.
文摘Background:To appraise the ameliorative potentials of Allium sativum aqueous extract in ovalbumin(OVA)-lipopolysaccharide(LPS)-induced asthma.Methods:Extraction,phytochemical analysis,determination of bioactive compounds and LD50 study of aqueous extract of A.sativum were achieved using standard biochemical methods.Twenty-four(24)male Wistar rats averagely weighing between 168–255 g were grouped into four of six animals in each steel-metal cage.Groups 1 and 2 served as normal and positive groups respectively.Rats in groups 2–4 were sensitized and challenged with a combination of OVA and LPS.Groups 3 and 4 were administered 250 and 500 mg/kg b.w of aqueous extract of A.sativum respectively for two weeks.The effect of aqueous extracts of A.sativum in OVA and LPS-induced asthma on alterations in differential white blood cells,inflammatory cytokines,some serum biochemical as well as histological indicators of experimental rats were assessed.Results:The aqueous extract of 600 g of plant material yielded 74.1 g accounting for 11.9%of sample material used.The result of the Phytochemical analysis showed higher number of glycosides,flavonoids and phenols.The animals displayed zero behavioral adverse reaction when administered the aqueous extract up to the highest dose of 5,000 mg/kg b.w.Administrations of aqueous extract of A.sativum remarkably(P<0.05;95%confidence intervals CI)declined the levels of neutrophils,eosinophils and total white blood cell count as opposed to the untreated group.Levels of interleukin 4(IL-4),interleukin 5(IL-5),interleukin 13(IL-13)and immunoglobulin E(IgE)of groups 3 and 4 had a significant(P<0.05;95%CI)varying percentage reduction(IL-4=39.78%,49.51%;IL-5=34.66%,40.05%;IL-13=31.96%,30.81%;33.45%,21.38%)respectively in comparison to group 2(untreated).The result showed a significantly(P<0.05,95%CI)declined malonaldehyde(MDA)concentration and elevated catalase,decreased glutathione concentration and superoxide dismutase activity of the treatment groups compared to the untreated.Serum liver function enzymes including alkaline phosphatase,alanine transaminase,and aspartate transaminase in the groups receiving aqueous extract of A.sativum exhibited a significant(P<0.05;95%CI)reduction in levels compared to group 2(untreated).Conclusion:Findings from this study indicated that aqueous extracts of A.sativum have the potential to improve asthma symptoms by decreasing inflammatory cytokines and mitigating oxidative stress.This effect could enhance the efficacy of conventional treatments such as inhaled corticosteroids,including cortisone,hydrocortisone,dexamethasone,and prednisone,as well as bronchodilators,leukotriene modifiers,and biologic therapies.Further studies need to be carried out on human subjects and also expanded to other respiratory disorders like Chronic obstructive pulmonary disease and Coronavirus Disease 2019.
文摘Background: There are links between physical exercise, fine particles and the prevalence of exercise-induced bronchospasm (EIB). Objective: The aim of this study was to assess the prevalence of exercise-induced bronchospasm in students of sciences and techniques of physical activities and sports (STAPS) exercising in a hot, humid and relatively polluted environment. Methods: Twenty-two first-year undergraduate students, including 11 in PE and 11 in SPORT, aged 21.64 ± 1.80 years, participated in a football match. Resting spirometry was performed before and 5 minutes after the match. During the match, particulate matter (PM2.5 and PM10) was measured every 10 minutes around the football pitch. Ambient temperature and relative humidity were recorded. The diagnosis of EIB was based on a decrease in FEV1 of at least 10% after the match. If there was a decrease, the participant was considered susceptible to EIB. Results: Five subjects were positive for exercise-induced bronchospasm, a percentage of 22%. Ambient temperature and relative humidity were 34.22˚C ± 1.38˚C and 52.2% ± 4.97%, respectively. Concentrations of PM2.5 and PM10 were between 53.3 - 115.5 µg/m3 and 75.5 - 168.2 µg/m3, respectively, exceeding WHO limits. Conclusion: These results show a high incidence of exercise-induced bronchospasm in students without a history of asthma but exercising in a hot, humid and environment polluted by fine particles.
文摘BACKGROUND IgE plays a critical role in allergic inflammation and asthma pathogenesis.This study investigates the involvement of IgE cells in asthma exacerbation and evaluates the effectiveness of targeted interventions.AIM To evaluate the role of IgE in the exacerbation of allergic asthma and to determine the clinical efficacy of anti-IgE therapy in improving disease outcomes.Specifically,the study investigates changes in serum IgE levels,lung function,asthma control scores,and the frequency of acute exacerbations among patients receiving standard therapy with or without anti-IgE intervention.METHODS A total of 200 patients diagnosed with moderate to severe asthma were enrolled in this experimental study conducted from April 2024 to April 2025.Participants were randomized to receive either standard asthma therapy or therapy combined with anti-IgE agents.IgE levels and asthma control parameters were monitored.RESULTS Participants receiving anti-IgE treatment demonstrated a significant reduction in serum IgE levels(P<0.001),improved Forced expiratory volume in one second scores,and fewer exacerbation episodes compared to the control group.CONCLUSION IgE cells significantly contribute to asthma severity,and targeted therapy against IgE can improve disease outcomes.These findings underscore the importance of immunomodulatory strategies in asthma management.

文摘Background:Chronic rhinosinusitis(CRS)is a prevalent inflammatory disease of the nasal and paranasal sinuses,affecting millions worldwide and significantly impacting quality of life.The pathogenesis of CRS involves complex interactions between environmental and host factors,leading to chronic inflammation and tissue remodeling.Purpose of review:This narrative review synthesizes recent research on the predisposing factors of CRS and their potential influence on disease endotypes,aiming to enhance understanding of this multifaceted condition.Recent findings:Identified predisposing factors include allergy,asthma,immune deficiency,gastroesophageal reflux,nasal anatomical variations,microbial infections,and others.Bacteria and biofilms,particularly Staphylococcus aureus,are significant in disease onset and severity.Immune deficiency may predispose individuals to CRS,and NSAID-exacerbated respiratory disease(N-ERD)is associated with more severe symptoms.Gastroesophageal reflux disease(GERD)and primary ciliary dyskinesia(PCD)also contribute to CRS development,with PCD leading to impaired mucociliary clearance and chronic inflammation.Conclusion:CRS is a multifactorial disease with various predisposing factors influencing its development and endotypic classification.Understanding these factors and their interactions with the immune system is crucial for developing targeted treatments and improving patient outcomes.
文摘In China,omalizumab is indicated for patients with moderate to severe persistent allergic asthma in whom symptoms remain inadequately controlled despite treatment with inhaled corticosteroids(ICS)in combination with long actingβ-agonists(LABA)(GINA step 3 or higher),and urticaria.We report a case of joint and Achilles tendon inflammatory reactions in a patient with Th2-type asthma receiving omalizumab treatment.An adult male presented with recurrent episodes of sneezing,rhinorrhea,wheezing,chest tightness,shortness of breath,and dyspnea.He exhibited allergies to multiple substances and demonstrated impaired lung function,ultimately being diagnosed with allergic rhinitis and asthma.Following initial treatment with ICS and LABA,his symptoms were initially controlled.However,as the disease progressed,the frequency of nocturnal attacks increased,and the incidence of attacks during the allergy season escalated,leading to a significant decline in lung function.Subsequently,he commenced subcutaneous injections of omalizumab at a dosage of 600 mg monthly.There was a partial improvement in the frequency of asthma attacks after two injections.Unfortunately,four days after the first treatment,he reported pain in the right Achilles tendon.Rheumatological screenings,including a five-item antinuclear antibody test and an 11-item autoantibody profile test,revealed no significant abnormalities.Ankle joint ultrasound indicated hyperechoic spots around the Achilles tendon with acoustic shadows,suggesting the presence of Achilles tendinopathy.Ten days later,the pain symptoms resolved spontaneously.Due to the sig-nificant improvement in asthma symptoms,omalizumab treatment continued,albeit with a dosage reduction to 300mg.After intermittent treatment over four sessions,asthma symptoms improved markedly,with the Asthma Control Test(ACT)score increasing from 14 to 20.Lung function improved from moderate obstruction to mild obstruction.The only drawback was the patient’s recurrent swelling,pain,and joint effusion in the joints(specifically the knee and ankle)during the treatment period.Omalizumab is an effective therapeutic option for the treatment of allergic asthma.Although the incidence of adverse events reported in current studies is low,there have been emerging reports of joint swelling,pain,and myalgia reactions in both children and adults receiving treatment for asthma and urticaria.Given the rarity and non-specific nature of these reactions,it is challenging to ascertain the true incidence rate.Previous reports have described symptoms that occur upon initiation of the medication,which can recur upon re-administration.While the factors that may increase the risk of joint inflammatory reactions to omalizumab remain to be elucidated,this case contributes to a deeper understanding of this adverse reaction associated with a well-tolerated and important therapeutic agent.
文摘Objective:To analyze the clinical value of Pulmicort Respules inhalation combined with cetirizine in the treatment of pediatric asthma.Methods:From December 2023 to December 2024,82 children with asthma admitted to our hospital were randomly divided into a control group and an observation group,with 41 cases in each group.The clinical symptom relief time(shortness of breath,cough,dyspnea,lung wheezing),lung function indicators(FEV1,FVC,FEV1/FVC),inflammatory indicators(TNF-α,IL-6,IL-8),and clinical treatment effects were analyzed in the two groups.Results:The relief time for shortness of breath,cough,dyspnea,and lung wheezing in the observation group was shorter than that in the control group(P<0.05).After treatment,compared with the control group,the levels of FEV1,FVC,FEV1/FVC,and treatment efficiency in the observation group were higher,while the levels of TNF-α,IL-6,and IL-8 were lower(P<0.05).Conclusion:The combination of Pulmicort Respules inhalation and cetirizine oral therapy for children with asthma can shorten the improvement time of clinical symptoms,inhibit inflammation,and improve lung function.

文摘BACKGROUND Current drugs primarily target inflammation control but do not reverse tissue remodeling changes for asthma.Human mesenchymal stem cells are known for their anti-inflammatory and tissue remodeling capabilities.However,limited research has explored the therapeutic impact of varying doses and frequencies of human umbilical cord blood-derived mesenchymal stem cells(HUC-MSCs)on established airway remodeling in experimental asthma.AIM To explore and optimize the dosage and administration frequency of HUC-MSCs in experimental models of ovalbumin(OVA)-induced asthma.METHODS BALB/c mice underwent sensitization and were challenged using OVA.Control animals were administered a saline solution following the same protocol.HUC-MSCs were identified using flow cytometry.HUC-MSCs at incremental dosages(1×105,2×105,4×105)were injected via tail veins on day 30(the second after the final stimulation).After comparing each group and determining the optimal dose,supplement the optimal dose twice on day 30 and day 33(the second and fifth day after the final stimulation).Bronchoalveolar lavage fluid(BALF)and serum were harvested for analysis of concentrations of interleukin-4(IL-4),IL-13,immunoglobulin E and interferon-gamma(IFN-γ)by enzyme-linked immunosorbent assay.Pharmacology of airways and lung functions were also evaluated to identify the optimal group.RESULTS The study shows that HUC-MSC transplantation ameliorates OVA-induced asthma by significantly reducing airway inflammation and obstruction in preclinical models.This effect is associated with decreased Th2 cytokines IL-4 and IL-13,and increased Th1 cytokine IFN-γ.The optimal dose of 2×105 cells/mouse was identified as the most effective in reducing local asthmatic airway inflammation and changing levels of IL-4,IL-13,and IFN-γin serum and BALF compared to other single doses of HUC-MSC.Multiple treatments with the medium dose(2×105 cells)of HUC-MSCs on days 30 and 33 yield the best pathological and lung function outcomes.However,double treatments do not reduce IL-4 and IL-13 expression or enhance IFN-γproduction in serum or BALF more effectively than a single medium dose.CONCLUSION HUC-MSCs effectively regulate pro-inflammatory mediators in serum and BALF,modulating airway remodeling and lung function.In this acute mouse asthma model,a single dosage of 2×105 is optimal,with more significant effects of decreasing airway obstruction requiring repeated administration.
文摘Asthma is the most common allergic disorder and represents a significant global public health problem.Strong evidence suggests a link between ascariasis and asthma.This study aims primarily to determine the prevalence of Ascaris lumbricoides infection among various risk factors,to assess blood parameters,levels of immunoglobulin E(IgE)and interleukin-4(IL-4),and to explore the relationship between ascariasis and asthma in affected individuals.The secondary objective is to examine a fractal-fractional mathematical model that describes the four stages of the life cycle of Ascaris infection,specifically within the framework of the Caputo-Fabrizio derivative.A case-control study was conducted that involved 270 individuals with asthma and 130 healthy controls,all of whom attended general hospitals in Duhok City,Iraq.Pulmonary function tests were performed using a micromedical spirometer.The presence of Ascaris lumbricoides antibodies-Immunoglobulin M(IgM),Immunoglobulin G(IgG),and Immunoglobulin E(IgE)-was detected using ELISA.Blood parameters were analyzed using a Coulter counter.The overall infection rate was(42.5%),with the highest rates observed among asthmatic men(70.0%)and rural residents(51.4%).Higher infection rates were also recorded among low-income individuals(64.3%)and those with frequent contact with the soil(58.6%).In particular,infected individuals exhibited a significant decrease in red blood cell count and hemoglobin concentration,while a marked increase in white blood cell count was recorded.In addition,levels of Immunoglobulin E(IgE)and interleukin-4 were significantly higher in the infected group compared to the controls.Effective disease awareness strategies that incorporate health education and preventive measures are needed.Exposure to Ascaris has been associated with reduced lung function and an increased risk of asthma.More research is required to elucidate the precise mechanisms that link Ascaris infection with asthma.Furthermore,the existence and uniqueness of solutions for the proposed model are investigated using the Krasnosel’skii and Banach fixed-point theorems.The Ulam-Hyers and Ulam-Hyers-Rassias stability types are explained within the framework of nonlinear analysis inŁp-space.Finally,an application is presented,including tabulated results and figures generated using MATLAB to illustrate the validity of the theoretical findings.

文摘Background:Allergic eosinophilic asthma(EA)and eosinophilic granulomatosis with polyangiitis(EGPA)share significant overlaps in both epidemiology and pathogenesis,suggesting a potential link between the two con-ditions.Despite these associations,the underlying molecular and cellular mechanisms driving their connection remain poorly understood.Methods:We retrieved GSE143303 of EA and GSE144302 of EGPA from the GEO database and conducted dif-ferential expression analysis as well as functional enrichment analysis to identify differentially expressed genes(DEGs)and potential pathogenic pathways.A protein-protein interaction(PPI)network was generated using the STRING database.Key hub genes were determined through cytoHubba.We added two publicly reported EA and EGPA-related transcriptome datasets,GSE117038 and GSE119136,for mutual verification.Subsequent valida-tion was performed via immune infiltration assessment utilizing CIBERSORT.Results:In total,267 DEGs were identified,in which HSP90AA1,HSPA8,CCND1,RPS20,CD74,RPL5,RPS6,RHOA,RPS3A and FLT3LG are the top 10 hub genes,while the antigen processing and presentation pathway and leukocyte cell-cell adhesion pathway were the potential influential pathways.Increased naïve B cells and M1 type of Macrophages were detected in EA patients through immune infiltration analysis.Conclusions:Utilizing bioinformatics techniques,this study is the initial investigation to uncover the shared mechanisms involving the antigen processing and presentation pathway and leukocyte adhesion pathways in the progression of both EA and EGPA.It may offer potential biomarkers for future studies on the underlying path-ogenesis and treatment of EA and EGPA as well as eosinophilia related co-morbidities.
文摘Objective Asthma imposes a significant global health burden.This study examines changes in the asthma-related disease burden from 1990 to 2021 and projects future burdens for 2050 under different scenarios.Methods Using data from the Global Burden of Disease 2021 study,we analyzed asthma incidence,prevalence,mortality,and disability-adjusted life years(DALYs)from 1990 to 2021.We projected the disease burden for 2050 based on current trends and hypothetical scenarios in which all risk factors are controlled.Temporal trends in age-standardized incidence,prevalence,mortality,and DALY rates were explored using Annual Percent Change.Results In 2021,the age-standardized rates for asthma incidence,prevalence,mortality,and DALYs in China were 364.17 per 100,000(95%uncertainty interval[UI]:283.22-494.10),1,956.49 per 100,000(95%UI:1,566.68-2,491.87),1.47 per 100,000(95%UI:1.15-1.79),and 103.76 per 100,000(95%UI:72.50-145.46),respectively.A higher disease burden was observed among Chinese men and individuals aged 70 years or older.Compared to the current trend,a combined scenario involving improvements in environmental factors,behavioral and metabolic health,child nutrition,and vaccination resulted in a greater reduction in the disease burden caused by asthma.Conclusion Addressing modifiable risk factors is essential for further reducing the asthma-related disease burden.
文摘1|Goalie Phenomenon The goalie phenomenon describes a group of health issues that may become apparent in children who prefer playing as goalkeepers.This preference might not only be about the excitement of the role but also as a coping mechanism for underlying health issues that make continuous running and high physical exertion challenging.The term highlights how certain positions in sports can sometimes obscure or reveal hidden health conditions,particularly among young athletes[1–3].To our knowledge,this is the first paper to formally introduce the term“Goalie phenomenon”in the literature exploring exerciseinduced asthma and sports role preferences in children.
文摘Air pollution has emerged as one of the most pressing public health challenges of the twenty-first century.According to the World Health Organization(WHO),more than 7 million premature deaths occur annually as a direct consequence of exposure to polluted air,which is estimated to affect over 90%of the global population.Air pollution manifests in two principal forms:outdoor pollution,largely driven by industrial emissions,transportation,and energy production,and indoor pollution,often linked to inadequate ventilation,heating systems,and household fuel use.Both forms contribute significantly to a wide range of health outcomes,including chronic respiratory illnesses,cardiovascular complications,strokes,and various types of cancer.Vulnerable groups—such as children,the elderly,and individuals with pre-existing medical conditions—are disproportionately at risk.Efforts to mitigate the harmful effects of air pollution include stricter emission regulations,adoption of clean and renewable technologies,expansion of sustainable public transportation networks,and public education campaigns aimed at raising awareness of health risks and preventive strategies.Uzbekistan is not exempt from these challenges.In particular,the Navoi region,recognized as one of the country’s most industrialized areas,faces heightened exposure to harmful substances released into the atmosphere.A comparative analysis of air quality indicators in Navoi’s urban centers before and after the COVID-19 pandemic revealed a significant post-pandemic rise in pollution levels,linked to economic recovery,industrial activity,and transport flows.These findings provide valuable insights for policymakers and local authorities in developing targeted environmental and public health interventions.
