A Herbal Concoction of Cinnamomum cassia and Artemisa annua Extracts Ameliorates Allergic Rhinitis in OVA-Induced Balb/C Mice by Inhibiting Th2 Signaling

Allergic rhinitis (AR) is an inflammatory airway disease (IAD) that is characterized by itching, nasal obstruction, and sneezing. AR is induced by Th-2 inflammatory responses such as those mediated by IgE and IL-4. This study aims to investigate the therapeutic effects of an herbal concoction, which is a combination of Cinnamomum cassia and Artemisa annua extracts (CIAR) against ovalbumin (OVA)-induced allergic rhinitis in a Balb/C mouse model. The effect of CIAR on the Th-2 mediated inflammatory response in the AR mouse model was studied by analyzing blood or nasal fluid samples. Experimental results revealed that OVA inhalation increased IgE, IL-4, IL-33, and TSLP levels, leading to Th2-type cytokine response. CIAR was found to significantly reduce the Th-2 response and levels of cytokines, including IL-4, IL-33, and thymic stromal lymphopoietin (TSLP). CIAR also down-regulated eosinophil (EOS) and basophil (BASO) levels in the blood. Histological analyses demonstrated decreased OVA-induced thickness of the respiratory epithelium in the CIAR-treated group. Collectively, our results suggest that the herbal concoction CIAR can effectively ameliorate the development of allergic rhinitis through the inhibition of Th-2 mediated responses.

Equine astma: huidige kennis van zaken

Equine astma is de overkoepelende term voor een inflammatoir proces ter hoogte van de diepere luchtwegen. Deze aandoening wordt verder onderverdeeld in lichte tot matige astma, beter bekend als “inflammatory airway disease” (IAD), en ernstige astma, beter bekend als “recurrent airway obstruction” (RAO). RAO veroorzaakt inflammatie en obstructie van de diepe luchtwegen, wat leidt tot chronische hoest, verhoogde ademhalingsinspanning in rust en inspanningsintolerantie, meestal bij paarden ouder dan zeven jaar. IAD daarentegen kan op elke leeftijd voorkomen en de klinische tekenen zijn vaak veel subtieler, namelijk verminderd presteren en occasioneel hoesten. Equine astma wordt voornamelijk getriggerd door een hoge concentratie aan stof en schimmelsporen in de stalomgeving of pollen tijdens de zomermaanden in het geval van “summer pasture associated” RAO (SPARAO). De gouden standaard om equine astma te diagnosticeren is het uitvoeren van een endoscopie, gevolgd door een broncho-alveolaire lavage (BAL). Het aanpassen van de omgeving is en blijft de belangrijkste behandelingsmethode, vaak in combinatie met het tijdelijk toedienen van corticosteroïden en bronchodilatatoren.

Novel Aspects of Insulin-like Growth Factor 1/insulin Network in Chronic Inflammatory Airway Disease

At least a proportion of patients suffering from chronic inflammatory airway diseases respond poorly to the bronchodilator and corticosteroid therapies. There is a need for the development of improved anti-inflammatory treatment. Insulin Growth Factor 1 (IGF1) and insulin participate in not only metabolism and glucose homeostasis, but also many other physiological and pathophysiological processes, including growth and inflammation. Recently, it was shown that not only the classical IGF1 and IGF1 Receptor (IGF1R), but also the other molecules in the IGF1/insulin network, including insulin, insulin-like growth factor-binding protein (IGFBP), and IGFBP protease, have roles in chronic inflammatory airway diseases. This review aims to provide a comprehensive insight into recent endeavors devoted to the role of the IGF1/insulin network in chronic inflammatory airway diseases. Its participation in airway inflammation, remodeling, and hyper-responsiveness (AHR), as well as acute exacerbation, has been conclusively demonstrated. Its possible relation to glucocorticoid insensitivity has also been indicated. A better understanding of the IGF1/insulin network by further bench-to-bedside research may provide us with rational clinical therapeutic approaches against chronic inflammatory airway diseases.

The role of eosinophilopoietins and integrins on eosinophils biology in asthma

Asthma is a chronic inflammatory airway disease that affects about 300 million peopleworldwide, and the incidence is continuously increasing. Patientswith asthma aremost commonly diagnosedwith type 2 inflammation,which is characterized by eosinophilia, which is an increased amount of eosinophils in the blood and airways. Asthma with predominant eosinophilic inflammation is characterized by amore severe course of the disease,more frequent exacerbations, andmore intense symptoms. To reduce symptoms, facilitate the course of the disease, and treat asthma more effectively is important to understand asthma pathogenesis better. Eosinophils survivalmaturation, activation, and quantity in the lungs are promoted by cytokines, of which eosinophilopoietins – interleukin (IL) 3, IL-5, and granulocyte-macrophage colony-stimulating factor (GM-CSF) are themost important. Eosinophilia is also associated with the activation of integrins present on the surface of eosinophils. Integrins areresponsible for eosinophils adhesion to airway structural cells, thus prolonging their survival leading to more intense airway eosinophilia. Eosinophilopoietins, their receptors, and integrins might be suitable targets reducing eosinophilia in blood and airway, as well as airway inflammation.Humanizedmonoclonal antibodies are used for this purpose. Biological therapy allows for the specific inhibition of relevant asthma pathways and offers patients individualized treatment. This review will discuss the biological significance of eosinophilopoietins and their receptors, integrins on eosinophils functions, anti-cytokine and anti-integrin therapy efficiency in asthma.

Association between inflammatory airway disease of horses and exposure to respiratory viruses: a case control study

Background: Inflammatory airway disease (IAD) in horses, similar to asthma in humans, is a common cause of chronic poor respiratory health and exercise intolerance due to airway inflammation and exaggerated airway constrictive responses. Human rhinovirus is an important trigger for the development of asthma; a similar role for viral respiratory disease in equine IAD has not been established yet. Methods: In a case–control study, horses with IAD (n = 24) were compared to control animals from comparable stabling environments (n = 14). Horses were classified using pulmonary function testing and bronchoalveolar lavage. PCR for equine rhinitis virus A and B (ERAV, ERBV), influenza virus (EIV), and herpesviruses 2, 4, and 5 (EHV-2, EHV-4, EHV-5) was performed on nasal swab, buffy coat from whole blood, and cells from BAL fluid (BALF), and serology were performed. Categorical variables were compared between IAD and control using Fisher’s exact test; continuous variables were compared with an independent t-test. For all analyses, a value of P <0.05 was considered significant. Results: There was a significant association between diagnosis of IAD and history of cough (P = 0.001) and exercise intolerance (P = 0.003) but not between nasal discharge and IAD. Horses with IAD were significantly more likely to have a positive titer to ERAV (68 %) vs. control horses (32 %). Horses with IAD had higher log-transformed titers to ERAV than did controls (2.28 ± 0.18 v.1.50 ± 0.25, P = 0.038). There was a significant association between nasal shedding (positive PCR) of EHV-2 and diagnosis of IAD (P = 0.002). Conclusions: IAD remains a persistent problem in the equine population and has strong similarities to the human disease, asthma, for which viral infection is an important trigger. The association between viral respiratory infection and development or exacerbation of IAD in this study suggests that viral infection may contribute to IAD susceptibility; there is, therefore, merit in further investigation into the relationship between respiratory virus exposure and development of IAD.

Equine asthma: managing the environment

Equine asthma is an umbrella term defined by nonseptic lower airway inflammation. Currently there are two broad categories, namely mild to moderate equine asthma (formerly known as inflammatory airway disease) and severe equine asthma (formerly known as recurrent airway obstruction or heaves). Environmental challenge is involved in the aetiopathogenesis of both these subcategories. Much of this challenge, and the part that we can control, is provided by the organic dust associated with the stabling of horses. This article reviews the available evidence relating to the environmental management of equine asthma and tries to relate this to practical options for providing a low-dust environment.
