The anti-interleukin (IL)-5 receptor benralizumab inhibits eosinophilic inflammation but its potential effect on airway remodeling remains unknown. The main objective of this study is to assess the effect of benralizumab in an in vitro model of airway remodeling using cells obtained from asthmatic patients.
The primary objective of this study is to assess the function and reliability of a non-invasive, skin-like electronic sensor. We hypothesize that this skin sensor will address an unmet need to wirelessly, noninvasively, and rapidly assess critical vital signs and other measures essential to healthcare monitoring for patients with asthma and anaphylaxis.
The role of vitamin D is well known in calcium and phosphate homeostasis; however, in addition to traditional functions, vitamin D has an important role in pathogenesis of different allergic diseases, such as asthma, atopic dermatitis (AD), and food allergy. There are evidences that lower cord blood vitamin D status is observed in infants with eczema. More-over, vitamin D level is decreased in subjects with asthma. One of the most important functions of vitamin D is to modulate the immune system response, both innate and adaptive, by suppressing Th2-type response and increasing natural killer cells. Vitamin D induces a higher level of IL-10, which is known as anti-inflammatory cytokine. Other studies have shown that vitamin D contributes to the conversion of CD4+ T cells to T regulatory cells. Recent studies showed that higher serum 25-hydroxyvitamin D level was associated with a reduced risk of asthma exacerbation and hospitalization. Vitamin D can enhance dexamethasone-induced MAP kinase phosphatase-1 (MKP-1) expression in peripheral blood mononuclear cells. Experimental data suggest that vitamin D can potentially increase the therapeutic response to glucocorticoid and can be used as an add-on treatment in steroid-resistant asthmatics. Vitamin D stimulates the production and regulation of skin antimicrobial peptides, such as cathelicidins, which have both direct antimicrobial activity and induced host cellular response by triggering cytokine release. Recent evidence suggests that low blood vitamin D level is a risk factor for food allergy. Vitamin D acts by binding to the vitamin D receptors (VDRs), which are located in a variety of tissues. VDRs have been identified on nearly all cells of the immune system including T cells, B cells, neutrophils, macrophages, and dendritic cells (DCs). Vitamin D deficiency predisposes to gastrointestinal infections by changing gut micro-biota, which may promote the development of food allergy. However the detail mechanism how vitamin D affects or protects the development of allergic diseases is still unknown. Vitamin D level is determined by sun exposure. Due to the fact that Lithuania, Latvia and Taiwan are located in different latitudes of north hemisphere with markedly different sun exposure, in this Joint collaboration study between Taiwan, Lithuanian and Latvia, we are going to study, (1). Serum vitamin D level in children and adults with AD and/or asthma in Lithuania, Latvia and Taiwan. (2). VDRs genetic polymorphisms of AD and/or asthma in children and adults in Lithuania, Latvia and Taiwan. (3). Finally, we would like to explore the gut microbiome of patients with AD and/or asthma in Lithuanian, Latvian and Taiwanese children and adults; and to estimate possible relationship between gut microbiome and vitamin D level and VDRs genetic polymorphisms. We believe that this study will be the first which compares the populations with different geographical and ecological factors having the same allergic diseases. We hope that these results will provide the answer about the role of vitamin D in the prevention, or in the future, in treatment of allergic diseases.
The purpose of this investigator-initiated study is to evaluate the effects of oral curcumin supplementation versus placebo in adult patients with moderate to severe asthma. Curcumin, a derivative of turmeric, has been shown in animal models to inhibit the secretion of pro-inflammatory cytokines and decrease airway constriction and hyperreactivity with only a few observational studies available in humans with discordant results.
A significant percentage of patients with asthma and COPD do not use their inhalers properly. Experts recommend that in patients with obstructive lung diseases, inhalation technique and patient adherence should be evaluated at every visit. The assessment of inhalation skills depends on the method of evaluation. There are few different methods of assessment of inhalation technique, however none of them is recommended as the most accurate. Therefore, the aim of the study is: 1. to compare three different methods of assessment of inhalation technique in patients with asthma and COPD. These methods include: 1. Checklist of mistakes in inhalation technique (including critical mistakes) 2. 4 grade scale of inhalation technique 3. Assessment by Vitalograph®AIM (Aerosol Inhaling Monitor) 2. to analyze the influence of Vitalograph®AIM based inhalation technique training on inhalation skills One hundred and thirty patients with asthma or COPD, who use inhaled medication on a regular basis will be enrolled. Inhalation technique will be evaluated by two observers independently at the same time with all three methods (checklist, 4 grade scale, Vitalograph®AIM). To compare these methods, the investigators will analyze method reliability and validity. Additionally, inhalation technique will be evaluated 30 minutes after Vitalograph®AIM based training to analyze the potential benefit of its application in practicing inhalation skills.
Asthma affects 1 in every 12 persons in the U.S., resulting in 1.9 million ED visits annually; however, the impact of ED care on patient-reported outcomes after acute exacerbations is unknown. The proposed research will train a physician-scientist to develop a novel instrument to assess patient-reported outcomes after adult ED asthma visits, evaluate the association between ED clinical processes and patient-reported outcomes, and test the association between patient-reported outcomes and subsequent acute care utilization. The candidate will acquire skills in patient-centered research, instrument development and validation, and risk adjusted outcome measurement that will enable her transition to independence.
Bronchial asthma is characterized by the presence of symptoms that vary over time and of severity. Asthma symptoms tend to worsen at night and in the early hours of the morning, and the presence of nocturnal symptoms is an important indicator of therapeutic intervention in order to control the severity of the disease. Aim of the study is to investigate sleep disorders and quality, as well as and depressive and anxiety symptoms in patients affected by severe asthma before and after 6 months of treatment with monoclonal therapy. An observational, cohort, prospective, monocentric study will be conducted to evaluate subjective quality of sleep at baseline and post monoclonal treatment.
Managing and taking medications as prescribed can be a difficult task. This is especially true for older adults living at home with chronic conditions while managing multiple prescribed medications. In response, Catalyst Healthcare has adopted an integrated medication dispensing system that intends to improve patient adherence to medications and quality of care through real-time pharmacists and caregiver support.Catalyst Healthcare has launched an integrated at-home medication dispenser system called spencer. Spencer is a natural extension that plugs into Catalyst's AdhereNet platform, connecting high-risk patients in home care setting to a multi-disciplinary care team in real-time. Study is funded by the Centre of Aging and Brain Health Innovation (CABHI). Investigators are conducting a randomized controlled trial with a target sample size of 100 participants to examine the efficacy of an in-home electronic medication dispensing system (MDS) on improving medication adherence in community-dwelling older adults with chronic conditions. 50 of these participants will be assigned to the intervention group (medication management with Spencer) and 50 will be assigned to the control group (medication management without Spencer). Medication adherence and patient-related data will be collected over a six-month period. Participants health status and characteristics will be obtained through baseline assessment upon enrollment. A monthly follow-up survey will be completed to collect medication management and adherence data. Adherence data for spencer-users will be collected from Catalyst Healthcare technology platform. In the control group, adherence will be measured through monthly medication logs completed by participants.
The Allergen Reduction and Child Health Study (ARCHS) is a 12-month, two group randomized control trial of children with asthma and who are exposed to cockroaches. Children ages 5 - 17 living in the Greater New Orleans area will be recruited from a variety of clinic and community settings. The overall goal of the study is to improve patient-centered asthma outcomes (asthma symptom days, health care utilization, asthma control and quality of life) by targeting one key allergen - cockroach exposure in the child's home. The investigators propose a simple intervention of insecticidal bait that is low cost, simple to implement, and which is lower toxicity than other forms of pest control. The reduction in the number of cockroaches in the home is an environmental outcome that is patient-centered and is likely to add to its acceptance by families of children with asthma.
