Clarifying the relationship and analyzing the influential factors of bronchial asthma in children with attention-deficit hyperactivity disorder

BACKGROUND Bronchial asthma is closely related to the occurrence of attention-deficit hyperactivity disorder(ADHD)in children,which can easily have adverse effects on children’s learning and social interactions.Studies have shown that childhood asthma can increase the risk of ADHD and the core symptoms of ADHD.Compared with children with ADHD alone,children with asthma and ADHD are more likely to show high levels of hyperactivity,hyperactive-impulsive and other externalizing behaviors and anxiety in clinical practice and have more symptoms of somatization and emotional internalization.AIM To explore the relationship between ADHD in children and bronchial asthma and to analyze its influencing factors.METHODS This retrospective cohort study was conducted at Dongying People's Hospital from September 2018 to August 2023.Children diagnosed with ADHD at this hospital were selected as the ADHD group,while healthy children without ADHD who underwent physical examinations during the same period served as the control group.Clinical and parental data were collected for all participating children,and multivariate logistic regression analysis was employed to identify risk factors for comorbid asthma in children with ADHD.RESULTSSignificant differences were detected between the ADHD group and the control group in terms of family history ofasthma and allergic diseases, maternal complications during pregnancy, maternal use of asthma and allergymedications during pregnancy, maternal anxiety and depression during pregnancy, and parental relationshipstatus (P < 0.05). Out of the 183 children in the ADHD group, 25 had comorbid asthma, resulting in a comorbidityrate of 13.66% (25/183), compared to the comorbidity rate of 2.91% (16/549) among the 549 children in the controlgroup. The difference in the asthma comorbidity rate between the two groups was statistically significant (P <0.05). The results of the multivariate logistic regression analysis indicated that family history of asthma and allergicdiseases, maternal complications during pregnancy, maternal use of asthma and allergy medications duringpregnancy, maternal anxiety and depression during pregnancy, and parental relationship status are independentrisk factors increasing the risk of comorbid asthma in children with ADHD (P < 0.05).CONCLUSIONChildren with ADHD were more likely to have comorbid asthma than healthy control children were. A familyhistory of asthma, adverse maternal factors during pregnancy, and parental relationship status were identified asrisk factors influencing the comorbidity of asthma in children with ADHD. Clinically, targeted interventions basedon these factors can be implemented to reduce the risk of comorbid asthma.

Research Progress on Pulmonary Rehabilitation in Children with Bronchial Asthma

Bronchial asthma is a chronic respiratory disease that poses a significant threat to the physical and mental health of children globally.Currently,pulmonary rehabilitation is a non-pharmacological intervention that has shown promise in treating chronic respiratory diseases.However,most studies related to pulmonary rehabilitation only focus on chronic conditions such as chronic obstructive pulmonary disease(COPD),lung cancer,and bronchiectasis.Research on bronchial asthma in children is still in the preliminary stages.This article reviews the concept,basic content,and application mode of pulmonary rehabilitation,to provide reference for the clinical research of pulmonary rehabilitation in children with bronchial asthma,and to carry out multimodal pulmonary rehabilitation to improve the disease control level and quality of life of asthma in children.

Efficacy and Impact on Inflammatory Factors and Lung Function in Pediatric Bronchial Asthma Treated with Modified Dingchuan Decoction

Objective:To study the efficacy of treating pediatric bronchial asthma with a modified Dingchuan Decoction and its effect on inflammatory factors and lung function levels.Methods:Sixty cases of bronchial asthma admitted to the hospital between January and December 2023 were divided into two groups using a computerized randomization method.One group of 30 cases received basic treatment with a salmeterol ticarcoson powder inhaler(control group),while the observation group received the same treatment plus a modified Dingchuan Decoction.The disappearance time of symptoms,levels of inflammatory factors,lung function indexes,and clinical efficacy were compared between the two groups.Results:The disappearance time of symptoms in the observation group was shorter than that in the control group.The levels of inflammatory factors after treatment were lower,and lung function indexes were higher in the observation group compared to the control group.Additionally,the total effective rate of treatment in the observation group was higher than that in the control group(P<0.05).Conclusion:In the clinical treatment of pediatric bronchial asthma,supplementing conventional Western medicine with a modified Dingchuan Decoction is effective,as it actively reduces inflammatory factor levels and improves lung function.

Analysis of the Effect of Non-Invasive Positive Pressure Ventilation in Emergency Treatment of Severe Bronchial Asthma with Respiratory Failure

Objective:This study aims to evaluate the clinical efficacy of non-invasive positive pressure ventilation(NIPPV)in patients with severe bronchial asthma combined with respiratory failure.Methods:90 patients with severe bronchial asthma combined with respiratory failure between September 2022 and December 2023 were selected for the study and randomly divided into the experimental group(NIPPV-assisted treatment)and the control group.The differences between the two groups were compared in terms of total effective rate of treatment,days of clinical symptom disappearance,days of hospitalization,lung function indexes,incidence of adverse reactions,and quality of life.Results:Patients in the experimental group had a significantly higher total effective rate of treatment(97.78%)than the control group(75.56%).In terms of pulmonary function indexes,patients in the experimental group showed significant improvement after treatment,especially the increase in forced expiratory volume and forced vital capacity,while these improvements were not as obvious in the control group.In addition,the incidence of adverse reactions was significantly lower in the experimental group than in the control group,suggesting that the application of NIPPV is relatively safe.Quality of life assessment also showed that patients in the experimental group had significantly better quality of life than the control group after treatment.Conclusion:This study demonstrated the effectiveness of NIPPV as an adjunctive treatment for severe bronchial asthma combined with respiratory failure.NIPPV can improve lung function,reduce the incidence of adverse effects,increase the overall effectiveness of the treatment,and contribute to the improvement of patients'quality of life.Therefore,NIPPV should be regarded as an effective and safe treatment in clinical management,especially in patients with severe bronchial asthma combined with respiratory failure,where its application has potential clinical significance.

The Effects of Omega-3 Fatty Acids Supplementation in Bronchial Asthma

Bronchial asthma is a chronic inflammatory disease. Allergies are intensely related to bronchial asthma and to other respiratory diseases such as chronic sinusitis, middle ear infections, and nasal polyps. Treatment can vary from inhalers to oral medications to drugs delivered in a nebulizer or breathing machine. Besides, dietary involvement was a significant tool to reduce the severity of many chronic inflammatory diseases including asthma. Randomly assigned, double blind, and placebo controlled 290 adults with mild to moderately persistent bronchial asthma concluded in this study, were subjected to alternating phases of supplementation with omega-3 fatty acids, vitamin C and Zn either singly or in combination. Subjective symptom improvement, pulmonary function, and biochemical tests were carried out at the beginning of the study and at the end of each therapeutic phase. The study findings showed that nearly half of the cases were in age between 18 years to 40 years followed by 29.6 of the cases that fall in age range between 40 years and 60 years. It was clear that all the four supplements (ogema-3 fatty acids, vitamin C and Zn, and combination) contributed more than placebo in reducing the severity of bronchial asthma. However, omega 3 fatty acids and combined supplement significantly contributed in symptomatic improvement (p < 0.05). There was a significant improvement of pulmonary function and sputum inflammatory markers with diet supplementation (p < 0.05). So, the subjects with mild and moderately persistent bronchial asthma may get benefit from their dietary supplementation with omega 3 fatty acids, Zinc and vitamin C. It is evident from this study that omega 3 fatty acids and combined supplementation significantly improved the severity of bronchial asthma.

Comparison of Allergic Rhinitis and Bronchial Asthma Impacts on Tympanometric Parameters in Children at Kano, Nigeria

Background: Allergic rhinitis (AR) is a multifocal IgE-mediated type I hypersensitivity reaction that affects sino-nasal mucosa and is characterized by excessive sneezing, watery rhinorrhea, nasal itching, nasal stuffiness and eyes itching. Bronchial asthma (BA) is one of the common childhood diseases that affects the respiratory system characterized by recurrent cough, wheezing, chest tightness and difficulty with breathing. The two conditions are different manifestations of allergic disease of the airway;the composition of the inflammatory substrate in the mucosa of allergic patients is similar to the late-phase allergic response seen elsewhere in the respiratory tract, such as in bronchial asthma. Aim: The aim was to compare the impacts of allergic rhinitis and bronchial asthma on tympanometric parameters in children. Patients & Methods: This is a hospital based comparative cross-sectional study. Two groups of participants aged 4 - 12 years, one group with documented clinical diagnosis of allergic rhinitis and the other group with documented clinical diagnosis of bronchial asthma were consecutively selected from ear, nose and throat (ENT) and pediatrics cardiopulmonary outpatient clinics of Aminu Kano Teaching Hospital Kano respectively. Equal number of children aged 4 - 12 years with no history of ENT diseases or bronchial asthma that were selected from elementary schools within the same community served as a control group. An interviewer-administered questionnaire was filled out for all the participants, complete ENT and chest examinations were carried out and subsequently all the selected participants had tympanometry done, findings were recorded and analyzed. Results: The mean age of participants with bronchial asthma was found to be 7.5 ± 2.6 years while participants with allergic rhinitis had the mean age of 6.8 ± 2.1 years. The mean middle ear pressure (MEP) of participants with bronchial asthma was found to be -15.22 dapa and -40.32 dapa in those with allergic rhinitis. Acoustic reflex was found to be absent in 15.4% of the participants with bronchial asthma and 29.6% of allergic rhinitis participants. Type B tympanogram was found in 2.8% of bronchial asthma participants and 7.3% in participants with allergic rhinitis. Type C tympanogram was found in 4.6% of participants with bronchial asthma and 15.5% of participants with allergic rhinitis. Type A tympanogram was found in 90% of participants with bronchial asthma and 75% of participants with allergic rhinitis. The difference between type A, B and C tympanograms of participants with bronchial asthma and those with allergic rhinitis was found to be statistically significant (Type A χ2 = 14.62, df = 4, p value = 0.01, Type B χ2 = 14.06, df = 4, p value = 0.01, Type C χ2 = 17.01, df = 6, p value = 0.01). Conclusion: Participants with allergic rhinitis were found to have more abnormalities of tympanometric parameters compared to participants with bronchial asthma which signifies allergic rhinitis conferred an increased risk of having middle ear diseases and otitis media with effusion compared to bronchial asthma.

The cross-talk between family and pediatrician: The case of bronchial asthma

Today the most important challenge facing the pediatrician is the increasing prevalence of chronic diseases. With this regard, pediatricians play a key role in the management of these conditions. The closeness with the family, the knowledge of the clinical case and the care continuity allow the pediatrician to acquire a position of director of every case. When pathological events have a chronic feature, suddenly the quality of life of the whole family changes. For this reason the first communication of chronic disease is very important and the task of the pediatrician should be to provide a positive message to help the family in facing the difficulty of this new challenge. The bronchial asthma is the most common chronic disease worldwide. The incidence, the prevalence, and the mortality of the disease have increased in children over the past decades. These trends are particularly marked above all in preschool children. The success reached by Pediatricians is closely related to the compliance and the implementation of the therapy followed by the little patient and his family. With this regard authors, in this review, focus on the illustration of several strategies, based on the pediatrician’ skills and medicine documents, that can be used for the improvement of communication among pedia- trician-family and child, never forgetting the hu- man aspect of the same doctor, that should con- ciliate with the scientific knowledge in the taking care of a specific chronic disease.

Chinese and Uighur medicine diagnostic criteria of the evaluation of the Modern drug treatment side-effects in bronchial asthma patients

We studied Chinese and Uighur medicines and create an automated computer diagnostics system according to principals of Uighur medicine for evaluation of bronchial asthma patient′s state.498 patients with bronchial asthma were enrolled the automated computer diagnostic program.304 patients were evaluated in the process of drug and non-drug treatment.Savda asthma type of Uighur medicine do not corresponds with any of the defined clinico-pathogenetic variants of the disease.Thus,prevailing of atopic bronchial asthma with probability of 0.7 is defined with Savda categories with such as 'Lungs energy deficiency','Spleen energy deficiency' and 'Kidneys Yin deficiency'(P<0.01) variants in Chinese Medicine.The combination of infectious-dependent variant of bronchial asthma Abnormal Savda syndrome with atopy with a probability of 0.8 is accompanied by the categories of 'Hot and Full' asthma with such variants as 'Lungs energy deficiency' 'Spleen energy deficiency','Kidneys Yin deficiency'(P<0.01).Patients with an easier case of Abnormal Savda syndrome bronchial asthma in 71% of cases have prevailing diagnostic categories of 'External,Full and Cold' asthma.Patients with a harder case of Abnormal Savda in 74% of cases belongs to the categories of 'Internal,Empty and Hot' asthma.So,hormone dependency of the disease in 69% of cases is accompanied by the 'Kidneys Yin deficiency' variant and,if there is an aspirin component in the pathogenesis of mixed asthma,in 83% of cases 'Kidneys Yin deficiency' and 'Kidneys Yang deficiency' variants are defined.

Alterations in Antioxidant Vitamins in Bronchial Asthma and Its Correlation with Spirometry

Bronchial asthma may result in oxidant/antioxidant imbalance. Antioxidant vitamins E and C concentrations were estimated in plasma of asthmatics that were also simultaneously subjected to spirometry and matched with healthy controls showing significant changes in both the vitamin concentrations. Vitamin C showed strong correlation whereas vitamin E was not correlated with spirometry.

Prevalence of Self-Reported Respiratory Symptoms, Asthma and Chronic Bronchitis in Slum Area of a Rapidly Developing Indian City

Background: Poverty is an important surrogate marker for obstructive airway diseases (OAD). Slum constitutes a habitat wherein various poverty related parameters are perpetually prevalent in the ambience. 1/6th of world population lives in slums yet there is no information regarding their health status in context to asthma and COPD. Aims: We investigated the prevalence of asthma and chronic-bronchitis symptoms and associated risk-factors in slum habitats of Pune city. Methodology: 7062 adult slum-dwellers living in 12 slums of Pune city were cross-sectionally interviewed by local healthcare workers with respiratory health questionnaire which was designed using respiratory symptoms of validated European Community Respiratory Health Survey (ECRHS II) questionnaire and International Union against Tuberculosis and Lung Disease (IUATLD) bronchial symptoms questionnaire. Results: The overall prevalence of selfreported asthma symptoms was 10% (18 - 40 years: 6.5%;>40 years: 13.5%). The overall prevalence of chronic bronchitis was 8.5% [18 - 40 years: 7% (males: 7%, females: 7%);>40 years: 10% (males: 10%, females: 10%)]. Increasing age (p = 0.00), female gender (p = 0.001), unemployment (0.00) current smoking (p = 0.00) and ex-smoking (p = 0.004) emerged as significant risk factor for asthma. While, ex-smoking (p = 0.004) and low-education status (p = 0.00) emerged as significant risk factors for chronic bronchitis. Conclusion: In slums reporting of asthma and chronic-bronchitis symptoms was much higher than what has been reported earlier from India. Asthma was commonly seen in females, old age, unemployed and ever-smokers. While chronic bronchitis was commonly seen in ex-smokers and illiterate subjects. Chronic bronchitis was equally distributed amongst male and females, despite 0% prevalence of smoking in females.

Traditional Chinese Medicine Nursing Protocols for Wheezing Disease(Bronchial Asthma)

Wheezing disease( bronchial asthma) is a common but refractory disease among pulmonary diseases. It tends to attack repeatedly,and is difficult to be cured. In recent years,some studies have shown that effective traditional Chinese medicine( TCM) nursing interventions on the wheezing disease can significantly ameliorate the treatment compliance of patients,reduce the attack and improve the quality of life. Therefore,it is important for patients with different patterns of syndrome to receive effective and reasonable TCMnursing intervention. This article mainly explored the key points of common syndromes,TCMnursing methods and health guidance of wheezing disease in order to further develop the advantages of TCM,improve its efficacy and standardized its nursing behavior.

Exploring Action Mechanism of Sanzi Yangqin Decoction in Treating Bronchial Asthma Based on Network Pharmacology and Molecular Docking

[Objectives]To explore the molecular mechanism of Sanzi Yangqin Decoction in the treatment of bronchial asthma based on network pharmacology and molecular docking.[Methods]The components of Fructus Perillae,Semen Raphani and Semen Sinapis three traditional Chinese medicine-related components and targets of Feiduqing Sanzi Yangqin Decoction were obtained using Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),and the targets of bronchial asthma were obtained using Genecards and OMIM databases.Sanzi Yangqin Decoction"drug-active ingredient-target-disease"network was established with the aid of Cytoscape 3.7.2 software and network topology analysis was carried out.The gene ontology(GO)function enrichment analysis and the KEGG pathway enrichment analysis were performed by DAVID.The top 3 components and targets in the network topology analysis were respectively molecularly docked.[Results]Through network analysis,4 key active components were obtained,mainly luteolin,arachidonic acid,β-carotene,etc.;5 key targets,mainly NCOA2,PGR,PTGS2,etc.Through GO analysis,523 items(P<0.05)were obtained,including 396 items in biological process(BP),53 items in cell composition(CC),and 74 items in molecular function(MF).KEGG analysis generated 144 signal pathways(P<0.05),involving PI3K-Akt signal pathway,human cytomegalovirus infection,Kaposi's sarcoma-associated herpes virus infection,proteoglycans in cancer,prostate cancer,etc.The results of molecular docking showed that core active compounds such as luteolin andβ-carotene in Sanzi Yangqin Decoction had good affinity with NCOA2,PGR,PTGS2 and other target genes,which were similar to clinically recommended chemical drugs.[Conclusions]The active compounds luteolin and carotene in Sanzi Yangqin Decoction may mainly bind to targets such as NCOA2,PGR,PTGS2,and regulate multiple signaling pathways such as PI3K-Akt to play a role in treating bronchial asthma.It is intended to provide new ideas for the clinical application and research of Sanzi Yangqin Decoction.

Clinical effect of terbutaline injection aerosol inhalation combined with conventional drug therapy for acute attack of bronchial asthma in children

Objective: To study the clinical effect of terbutaline injection aerosol inhalation combined with conventional drug therapy for acute attack of bronchial asthma in children. Methods:Children with acute attack of bronchial asthma who were treated in Wusheng Hospital of Traditional Chinese Medicine and Qiandongnan Prefecture People's Hospital between January 2014 and July 2017 were selected as the study cases for prospective study and randomly divided into the experimental group who received terbutaline + budesonide aerosol inhalation and the control group who received budesonide aerosol inhalation. The expression levels of immune cell transcription factors in peripheral blood as well as the contents of adhesion factors, chemokines, proteases and their inhibitory molecules in serum were determined before treatment and 3 days after treatment. Results: Foxp3 and T-bet expression in peripheral blood as well as TIMP1 and TIMP2 contents in serum of both groups after treatment were higher than those before treatment whereas RORγt and GATA-3 expression in peripheral blood as well as TARC, Eotaxin, ICAM-1, VCAM-1, L-selectin, ADAM8, NE and MMP9 contents in serum were lower than those before treatment, and Foxp3 and T-bet expression in peripheral blood as well as TIMP1 and TIMP2 contents in serum of experimental group after treatment were higher than those of control group whereas RORγt and GATA-3 expression in peripheral blood as well as TARC, Eotaxin, ICAM-1, VCAM-1, L-selectin, ADAM8, NE and MMP9 contents in serum were lower than those of control group. Conclusion: Terbutaline injection aerosol inhalation combined with conventional drug therapy can effectively regulate the immune response and inflammatory response and inhibit the airway remodeling mediated by protease in children with acute attack of bronchial asthma.

Bronchial inflammatory profile in interferon-gamma-mediated immune response in asthma patients during airway response to cold stimulus

Objective:To evaluate the inflammatory pattern and the interferon(IFN)-γin the bronchial secretion of asthma patients in response to acute cold bronchoprovocation.Material and methods:We enrolled 42 patients with asthma.We assessed asthma by Asthma Control Test,the lung function by spirometry before and after the bronchodilator test,followed by collecting induced sputum.The next day,we collected exhaled breath condensate(EBC)and conducted a 3-minute isocapnic hyperventilation with cold air(IHCA),followed by collecting spontaneously produced sputum.Results:Group 1 included 20 patients with cold airway hyperresponsiveness(CAHR),and group 2 included 22 patients without CAHR.In both groups,a high level of neutrophils in bronchial secretion was observed before and after IHCA.In response to IHCA,the number of epitheliocytes in the sputum decreased to a greater extent in patients of group 1.The baseline epitheliocytes and the concentration of IFN-γafter IHCA had an inverse relationship(r=-0.60;P=0.017).The baseline IFN-γin EBC before and after IHCA was lower in group 1.Airway response to cold exposure directly correlated with IFN-γlevels after IHCA(Rs=0.42;P=0.014).Conclusion:In asthma patients with CAHR,there is a relationship between the persistence of mixed inflammation and the level of IFN-γin the bronchi.IFN-γin response to IHCA is decreased with increased cytokine utilization during cold bronchospasm,which is accompanied by the mobilization of neutrophils and the shift in the cytokine spectrum of the respiratory tract towards the T helper cells(Th)1 immune response.
