Abstract
Asthma is a chronic airway inflammatory disease that results from a complex interplay of genetic, environmental, and lifestyle factors. There is no cure for asthma, and the management is usually as per published guidelines. As in many chronic diseases conditions, various alternative or complimentary therapies have been tried. Of these, yoga and pranayama have gained wider attention in recent years. While the term yoga is a complex term encompassing eight limbs as per Patamjai in the yoga sutras, in simple terms, yoga is described as a combination of 'asana' (physical exercises) and 'pranayama' (breathing exercise). The term "asthma" has been derived from the Greek word "panting,", which indicates a rapid and shallow breathing. The main aim of yoga and pranayama in asthma is to synchronize and control breathing, thus decreasing hyperventilation. Besides this, they also decrease the stress/strain/anxiety, change in behavior, boost immunity, and improve strength/endurance of respiratory muscles that are helpful in any subject with asthma. There have been a good number of studies including clinical trials in children with asthma that have found some beneficial effects. In the present review, the physiology of yoga and pranayama, rationale for their use in children with asthma along with a summary of various studies conducted till date, have been discussed. These are followed by recommendations regarding their incorporation in the standard of care of children with asthma.

Int J Med Sci 2020; 17:1464-1473. [PMID: 32624703 PMCID: PMC7330667 DOI: 10.7150/ijms.45400] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Accepted: 05/29/2020] [Indexed: 12/17/2022] Open
Abstract
Berberine is an isoquinoline alkaloid isolated from various Chinese herbs that has potential of anti-inflammatory, anti-lipidemic, anti-neoplastic, and anti-diabetic activity. In this study, we evaluated the anti-inflammatory efficacy of berberine on allergic airway inflammation by targeting epithelial cells. Allergic airway inflammation driven by T helper 2 (Th2)-type immunity is characterized by airway hyperresponsiveness, elevated IgE production, and eosinophilic infiltration. For eosinophil recruitment, major chemoattractant CCL11 (eotaxin-1) was secreted by lung epithelial cells. BEAS-2B cells, a human bronchial epithelial cell line, were pre-treated with berberine and then activated by IL-4 plus TNF-α. The viability of BEAS-2B cells was assessed. Expression levels of IL-6 and CCL11 were determined using ELISA and real-time PCR. The signaling pathways of MAP kinases, NF-κB, and STAT6 were analyzed by western blot. Berberine treatment (≤1 μM) didn't significantly affect the viability of BEAS-2B cells with or without IL-4 plus TNF-stimulation. Berberine significantly inhibited the secretion of IL-6 and CCL11 from pro-inflammatory cytokine-activated BEAS-2B cells. NF-κB and MAP kinase pathways were seemingly unaffected in BEAS-2B cells with berberine treatment. Significant reduction of nuclear STAT6 protein expression in activated BEAS-2B cells with berberine treatment was observed. Current study reveals that berberine has inhibitory effect in pro-inflammatory cytokine-activated BEAS-2B cells through reducing IL-6 and CCL11 production, which is possibly modulated by suppressing STAT6 signaling pathway.

Abstract
Pediatric integrative medicine is an emerging field which, to date, has not been described in detail in academic medical centers in the United States. Early research of pediatric integrative medicine modalities shows promise for the treatment of common pediatric conditions such as irritable bowel syndrome, acute and chronic pain, headache, and allergy, among others. In light of the growing prevalence of pediatric illnesses and patient complexity, it is crucial to emphasize the patient's overall well-being. As academic centers around the world start to develop pediatric integrative medicine programs, the aim of this manuscript is to briefly highlight evidence of effective integrative treatments in pediatric subspecialties, to describe the establishment of our integrative medicine program, to summarize its early efforts, and to discuss potential barriers and keys to success.

Abstract
To describe the role of breathing exercises or yoga and/or pranayama in the management of childhood asthma. We conducted an updated literature search and retrieved relevant literature on the role of breathing exercises or yoga and/or pranayama in the management of childhood asthma. We found that the breathing exercises or yoga and/or pranayama are generally multi-component packaged interventions, and are described as follows: Papworth technique, Buteyko technique, Yoga and/or Pranayam. These techniques primarily modify the pattern of breathing to reduce hyperventilation resulting in normalisation of CO2 level, reduction of bronchospasm and resulting breathlessness. In addition they also change the behaviour, decrease anxiety, improve immunological parameters, and improve endurance of the respiratory muscles that may ultimately help asthmatic children. We found 10 clinical trials conducted in children with asthma of varying severity, and found to benefit children with chronic (mild and moderate) and uncontrolled asthma, but not acute severe asthma. Breathing exercises or yoga and/or pranayama may benefit children with chronic (mild and moderate) and uncontrolled asthma, but not acute severe asthma. Before these techniques can be incorporated into the standard care of asthmatic children, important outcomes like quality of life, medication use, and patient reported outcomes need to be evaluated in future clinical trials.

Abstract
The botanical, Astragalus membranaceus, is a therapeutic in traditional Chinese medicine. Limited literature exists on the overall in vivo effects of A. membranaceus on the human body. This study evaluates the physiological responses to A. membranaceus by measuring leukocyte, platelet, and cytokine responses as well as body temperature and blood pressure in healthy individuals after the in vivo administration of A. membranaceus. A dose-dependent increase in monocytes, neutrophils, and lymphocytes was measured 8-12 hours after administration and an increase in the number of circulating platelets was seen as early as 4 hours. A dynamic change in the levels of circulating cytokines was observed, especially in interferon-γ and tumor necrosis factor-α, IL-13, IL-6, and soluble IL-2R. Subjective symptoms reported by participants were similar to those typically experienced in viral type immune responses and included fatigue, malaise, and headache. Systolic and diastolic blood pressure were reduced within 4 hours after administration, while body temperature mildly increased within 8 hours after administration. In general, all responses returned to baseline values by 24 hours. Collectively, these results support the role of A. membranaceus in priming for a potential immune response as well as its effect on blood flow and wound healing.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Matrine has been isolated from Sophora flavescens, and found to show anti-inflammatory effects in macrophages and anti-cachectic effects in hepatomas. The present study investigated whether matrine suppressed eosinophil infiltration and airway hyperresponsiveness (AHR) in mice, and decreased the inflammatory response of tracheal epithelial cells. MATERIALS AND METHODS BALB/c mice were sensitized and challenged with ovalbumin to induce allergic asthma in mice. These asthmatic mice were given various doses of matrine by intraperitoneal injection. Additionally, activated human tracheal epithelial cells (BEAS-2B cells) were treated with matrine, and evaluated for levels of proinflammatory cytokines and chemokines. RESULTS We found that matrine significantly decreased AHR, and suppressed goblet cell hyperplasia, eosinophil infiltration, and inflammatory response in the lung tissue of asthmatic mice. Matrine also reduced the levels of Th2 cytokines and chemokines in bronchoalveolar lavage fluid, and suppressed OVA-IgE production in serum. Furthermore, matrine treatment of activated BEAS-2B cells decreased production of proinflammatory cytokines and eotaxins, as well as suppressed ICAM-1 expression and thus adhesion of eosinophils to inflammatory BEAS-2B cells in vitro. CONCLUSIONS Our findings suggest that matrine can improve allergic asthma in mice, and therefore has potential therapeutic potential in humans.

Abstract
Eosinophilia is one of the characteristic signs of allergic inflammation. Massive migration of eosinophils to the airways can cause epithelial tissue injury, contraction of airway smooth muscle and increased bronchial responsiveness. Previously, we discovered a new compound, 1H,8H-pyrano[3,4-c]pyran-1,8-dione (PPY), derived from the fruit of Vitex rotundifolia L. and evaluated its anti-inflammatory and anti-asthmatic properties. In this study, we synthesized a new modified compound, 4-acetyl-3-methyl-6-(3,4,5-trimethoxyphenyl) pyrano[3,4-c]pyran-1,8-dione (PPY-345), which was based on the PPY skeleton, and we evaluated its anti-asthmatic effects. To evaluate the anti-asthmatic effect of PPY-345 in vitro, A549 lung epithelial cells were stimulated with TNF-alpha, IL-4 and IL-1-beta to induce the expression of CCL11 (Eotaxin), a chemokine involved in eosinophil chemotaxis. To characterize the anti-asthmatic properties of PPY-345 in vivo, we examined the influence of PPY-345 in an ovalbumin (OVA)-induced asthma model. PPY-345 treatments significantly reduced CCL11 secretion. PPY-345 treatment did not inhibit the translocation of NF-κB into the nucleus but suppressed the phosphorylation of signal transducers and activators of transcription 6 (STAT6). PPY-345 treatment significantly reduced airway hyperreactivity as measured by whole-body plethysmography. PPY-345 further reduced total cells, including eosinophil, macrophage and lymphocytes, in the BAL fluid, goblet cell hyperplasia and myosin light chain 2 positive smooth muscle cell area in the lung tissue. Additionally, PPY-345 significantly suppressed the levels of OVA-IgE present in the serum. These results suggested that PPY-345 could improve asthma symptoms in OVA-sensitized mice.

Dietary acacetin reduces airway hyperresponsiveness and eosinophil infiltration by modulating eotaxin-1 and th2 cytokines in a mouse model of asthma. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 2012:910520. [PMID: 23049614 PMCID: PMC3462452 DOI: 10.1155/2012/910520] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/03/2012] [Revised: 08/23/2012] [Accepted: 08/25/2012] [Indexed: 12/18/2022]
Abstract
A previous study found that eosinophil infiltration and Th2 cell recruitment are important causes of chronic lung inflammation in asthma. The plant flavonoid acacetin is known to have an anti-inflammatory effect in vitro. This study aims to investigate the anti-inflammatory effect of orally administered acacetin in ovalbumin- (OVA-) sensitized asthmatic mice and its underlying molecular mechanism. BALB/c mice were sensitized by intraperitoneal OVA injection. OVA-sensitized mice were fed acacetin from days 21 to 27. Acacetin treatment attenuated airway hyperresponsiveness and reduced eosinophil infiltration and goblet cell hyperplasia in lung tissue. Additionally, eotaxin-1- and Th2-associated cytokines were inhibited in bronchoalveolar lavage fluid and suppressed the level of OVA-IgE in serum. Human bronchial epithelial (BEAS-2B) cells were used to examine the effect of acacetin on proinflammatory cytokines, chemokines, and cell adhesion molecule production in vitro. At the molecular level, acacetin significantly reduced IL-6, IL-8, intercellular adhesion molecule-1, and eotaxin-1 in activated BEAS-2B cells. Acacetin also significantly suppressed the ability of eosinophils to adhere to inflammatory BEAS-2B cells. These results suggest that dietary acacetin may improve asthma symptoms in OVA-sensitized mice.

Abstract
BACKGROUND In developed countries, increasing food allergy prevalence and concern regarding food allergies have been reported. Although the use of complementary and alternative medicine (CAM) for the treatment of allergic diseases has increased in some Western countries, the actual proportion and patterns of CAM use for pediatric food allergies in Japan are still unknown. METHODS Fourteen allergy centers in Japan participated in the study using a questionnaire survey regarding the use of CAM by pediatric patients. A diagnosis of food allergy was made at each hospital by pediatric allergists. RESULTS Surveys were completed by parents/guardians, and data were collected for a total of 962 pediatric food-allergic patients. Overall, 8.4% of the participants used CAM to treat a food allergy. The major CAM therapies used were herbal teas (22.2%), including several Japanese herbal teas, Chinese herbal medicine (18.5%) and lactic acid bacteria (16%). Among the participants using CAM to treat food allergy, 13.6% thought that the CAM being used was very effective, while 11.1% of participants thought that CAM caused some type of side effect. CONCLUSIONS Our study is the first large-scale national survey regarding the use of CAM in pediatric patients with food allergies in Japan. Unlike in the USA, which has a higher rate of CAM use (17%), approximately 8.4% of food-allergic patients used CAM in Japan. Interestingly, the major types of CAM used in Japan differed from those used in the USA. Cultural differences and food customs may affect the use of CAM.

Abstract
Prevalence of asthma and allergy has increased over the past 2-3 decades in Westernized countries. Despite increased understanding of the pathogenesis of asthma and allergic diseases, control of severe asthma is still difficult. Asthma is also associated with a high prevalence of anxiety, particularly in adolescents. There is no effective treatment for food allergy. Food allergy is often associated with severe and recalcitrant eczema. Novel approaches for treatment of asthma and food allergy and comorbid conditions are urgently needed. Traditional Chinese medicine, used in Asia for centuries, is beginning to play a role in Western healthcare. There is increasing scientific evidence supporting the use of traditional Chinese medicine for asthma treatment. Since 2005, several controlled clinical studies of "antiasthma" herbal remedies have been published. Among the herbal medicines, antiasthma herbal medicine intervention is the only antiasthma traditional Chinese medicine product that is a Food and Drug Administration investigational new drug that has entered clinical trials in the United States. Research into the effects and mechanisms of action of antiasthma herbal medicine intervention in animal models is actively being pursued. Research on traditional Chinese medicine herbal medicines for treating food allergy is rare. The herbal intervention Food Allergy Herbal Formula-2 is the only Food and Drug Administration botanical investigational new drug under investigation as a multiple food allergy therapy. This review article discusses promising traditional Chinese medicine interventions for asthma, food allergy, and comorbid conditions, and explores their possible mechanisms of action.

Abstract
BACKGROUND Danggui Buxue Tang (DBT), an herbal formula containing Angelica sinensis (AS) and Astragalus membranaceus (AM) (AS:AM = 1:5, designated as DBT1 here), has been used in Chinese medicine to enhance qi and blood circulation. In addition, DBT has served as a treatment for atopic dermatitis in dogs in Taiwan. It also may improve fibrosis in a rat model of pulmonary fibrosis. OBJECTIVE In this study, we evaluated the effect of oral administration of DBT1 in asthma in ovalbumin (OVA)-sensitized mice. METHODS Female BALB/c mice were sensitized and challenged with OVA and fed with DBT1 or modified formulas of DBT1, designated as DBT2 (AS:AM = 1:1) and DBT3 (AS:AM = 5:1), from days 21 to 27. RESULTS DBT1 suppressed airway hyperresponsiveness and eosinophil infiltration in bronchoalveolar lavage fluid (BALF) and lung, and Th2-associated cytokines and chemokines were inhibited in BALF. In addition, levels of OVA-immunoglobulin E (IgE) also were suppressed in serum. However, treatment with DBT2 or DBT3 showed no improved effects relative to DBT1 in treating asthmatic symptoms. CONCLUSIONS These results suggest that orally administered DBT (DBT1) can reduce allergic reactions in OVA-sensitized mice.

Abstract
AIM OF THE STUDY Viscum coloratum Nakai is used in traditional Chinese medicine to treat various diseases, including hemorrhage, hypertension, and inflammatory diseases. A previous study demonstrated a partially purified extract (PPE-SVC) and viscolin from Viscum coloratum Nakai inhibited phosphodiesterase activity. In this study, we evaluated the anti-asthmatic effects of PPE-SVC and viscolin, from Viscum coloratum Nakai, in OVA-sensitized mice. MATERIALS AND METHODS Female BALB/c mice were sensitized and challenged with ovalbumin (OVA). The mice were randomized into groups and treated with PPE-SVC, viscolin, or rolipram by intraperitoneal injection on 1h before each inhalation of OVA and airway hyperresponsiveness (AHR). RESULTS PPE-SVC and viscolin suppressed AHR and reduced eosinophil infiltration of the lungs in OVA-sensitized mice. Moreover, PPE-SVC and viscolin inhibited chemokines, including CCL11 and CCL24, and Th2-associated cytokines in bronchoalveolar lavage fluid. However, PPE-SVC and viscolin could not decrease IL-4, IL-5, and IL-13 levels in cultures of OVA-activated spleen cells. CONCLUSION PPE-SVC and viscolin attenuate airway inflammation and eosinophil infiltration in OVA-sensitized mice.

Abstract
With increased awareness of complementary/alternative medicine (CAM) and concern of potential adverse effects or limited effectiveness of conventional medications, patients and parents are looking to CAM approaches as either an alternative or as adjunct therapy, especially for chronic diseases such as asthma or cystic fibrosis. It is important that practitioners have adequate information so that patients and parents receive balanced and accurate information, especially regarding safety and potential efficacy. This review provides an overview of some of the more frequently used CAM therapies for children with chronic pulmonary disorders and summarizes the basic principles of each modality, along with efficacy and safety data.

Abstract
Asthma is a serious global health problem that affects people of all ages. The best strategy to reduce the mortality and morbidty of asthma is evidence-based management based on guidelines. National and international guidelines are available worldwide but they are not being implemented. The main barriers to implementation include difficulties in implementing a structured-care approach, advocated by guidelines in different healthcare systems, and patient noncompliance. Additional barriers in developing countries include poverty, inadequate resources and poor infrastructure. Many of these barriers are potentially correctable or ameliorable, and the goal of guideline implementation is to translate evidence-based asthma-management recommendations into real-life practice to improve patient health and reduce healthcare cost. This article reviews the challenges and current status of asthma management and highlights the new global initiatives for bringing optimal asthma care to asthma sufferers in resource-poor countries.

Liou CJ, Huang WC, Kuo ML, Yang RC, Shen JJ. Long-term oral administration of Gynostemma pentaphyllum extract attenuates airway inflammation and Th2 cell activities in ovalbumin-sensitized mice. Food Chem Toxicol 2010; 48:2592-8. [PMID: 20558230 DOI: 10.1016/j.fct.2010.06.020] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2010] [Revised: 06/08/2010] [Accepted: 06/10/2010] [Indexed: 01/20/2023]
Abstract
Our previous report demonstrated that the oral administration of short-term high dose Gynostemma pentaphyllum extract (5 g/kg per day for 7days) decreased allergic reactions in ovalbumin (OVA)-sensitized mice. The aim of this study was to determine whether long-term oral administration of G. pentaphyllum attenuated airway inflammation in OVA-sensitized mice. Mice were sensitized and challenged with normal saline or OVA. OVA-sensitized mice were fed with 1.75 g/kg (low dose, GPL) or 5 g/kg (high dose, GPH) G. pentaphyllum extract, five days a week for 4 weeks. The airway hyperresponsiveness (AHR) and eosinophilia in bronchoalveolar lavage fluid (BALF) were examined. The cytokine levels or antibodies in BALF, serum and spleen cell culture supernatants were also determined. Both high and low dose extracts reduced AHR, serum OVA-IgE, and Th2-associated cytokine levels in spleen cell supernatants and BALF in OVA-sensitized mice. These results show that long-term orally administered G. pentaphyllum extract reduced allergic reactions in OVA-sensitized mice.

Abstract
Nurses require current information about popular complementary and alternative medicine for pediatric asthma. This integrative review searched scientific literature in PubMed and WEB of Science from 2004 to 2009 via key terms: asthma complementary medicine, nursing complementary pediatric asthma, asthma herbal, and herbal pediatric asthma. Nine journal articles met the inclusion criteria of containing data collection and analysis for biologically based therapies for pediatric asthma. Evidenced-based research on this focus topic is still in its initial stages. Two themes of maximizing the diet and augmenting conventional therapy with Traditional Chinese Medicine may serve as conduits of patient education.

Abstract
Complementary and alternative medicine (CAM), more recently known as integrative health or integrative medicine, is a diverse field comprising numerous treatments and practitioners of various levels of training. This review defines several of the main CAM modalities and reviews some of the research relevant to their clinical application. The goal is to provide healthcare providers with a basic understanding of CAM to start the incorporation of proven treatments into their clinical practice as well as guide them to working with CAM providers; ultimately, such knowledge is a fundamental part of a collaborative approach to optimal patient health and wellness.

Abstract
PURPOSE OF REVIEW Allergic disorders represent a serious public health problem in children. The chronic nature of these diseases and the fear of known side effects of synthetic drugs influence many families to seek complementary and alternative medicine. This review focuses on traditional Chinese medicine (TCM) herbal products and acupuncture for treating pediatric allergies. RECENT FINDINGS Given the general safety profile and reputed efficacy, TCM are well received by the general population. However, compared with the long human history and popularity of the use of TCM, research into its efficacy and safety is still in its infancy. In the last 2-3 years, there have been more controlled studies of TCM for allergic asthma and allergic rhinitis. Several publications including ours indicate that some TCM herbal formulas are well tolerated and produce some level of efficacy. Some herbal formulas also showed beneficial immunomodualtory effects. Several preclinical studies demonstrated that the food allergy herbal formula-2 was effective in protecting against peanut anaphylaxis in animal models. Two TCM products have entered clinical trials in the United States for treating asthma and food allergy, respectively. Both of these trials include children. SUMMARY Recent studies indicate that TCM therapy including herbal medicines and acupuncture for allergic disorders in children is well tolerated. There are also promising clinical and objective improvements. More controlled clinical studies are encouraged.
