Calcilytics are pharmaceutical drugs that act as antagonists at the calcium-sensing receptor (CaSR). Recent monoclonal antibody (biological) therapies reduce obstruction and exacerbations in some, but not all treated patients to an unpredictable extent, but are further limited by administration logistics and cost. Introduction: (2019, June 18). This significant minority accounts for around 90% of healthcare costs associated with the condition. Published today in Science Translational Medicine journal, Cardiff University researchers, working in collaboration with scientists at King's College London and the Mayo Clinic (USA), describe the previously unproven role of the calcium sensing receptor (CaSR) in causing asthma, a disease which affects 300 million people worldwide. The team used mouse models of asthma and human airway tissue from asthmatic and non-asthmatic people to reach their findings. Five per cent of people with asthma don't respond to current treatments so research breakthroughs could be life changing for hundreds of thousands of people. Cardiff University scientists have for the first time identified the potential root cause of asthma and an existing drug that offers a new treatment. HHS Asthma; bronchial hyperresponsiveness; calcilytic; calcium sensing receptor; inflammation; therapy. Scientists at the Cardiff University and the Kings College London have found out what causes asthma, and how to switch it off. Treat comorbid conditions. It is a serious global health problem affecting all age groups, with increasing prevalence in many developing countries, rising treatment costs, and a rising burden for patients and the community.

Asthma is a disease in which the airways swell up and tighten, making it hard to catch your breath. Epub 2020 Oct 28. Professor Riccardi and her collaborators are now seeking funding to determine the efficacy of calcilytic drugs in treating asthmas that are especially difficult to treat, particularly steroid-resistant and influenza-exacerbated asthma, and to test these drugs in patients with asthma. Consider allergic bronchopulmonary aspergillosis, gastroesophageal reflux, obesity, obstructive sleep apnea, rhinitis … This post from The Telegraph reports news of asthma … These difficulties result from your airways narrowing and swelling. "If we can prove that calcilytics are safe when administered directly to the lung in people, then in five years we could be in a position to treat patients and potentially stop asthma from happening in the first place," added Professor Riccardi. Bass, Kate. Asthma also leads to … Find out about asthma including symptoms, diagnosis, treatment, patient stories, support, and more from an asthma community perspective. ... and to test these drugs in patients with asthma. "If we can prove that calcilytics are safe when administered directly to the lung in people, then in five years we could be in a position to treat patients and potentially stop asthma from happening in the first place," Dr. Daniela Riccardi from Cardiff University explained in the press release. 2009 Sep;65(9):853-71. doi: 10.1007/s00228-009-0682-z. While asthma is well controlled in some people, around one-in-twelve patients respond poorly to current treatments. "Our findings are incredibly exciting," said the principal investigator, Professor Daniela Riccardi, from Cardiff University School of Biosciences. It is predicted that by 2020 these diseases will be the third biggest killers worldwide. National Prevalence of Asthma Attacks 1 among People with Current Asthma 2 by Age (2018) Characteristic Weighted number with asthma attack 1 Percent (SE) Total: 11,222,479: 45.4 (1.23) Child (Age <18 years) 2,965,929: 53.8 (2.70) Adult (Age 18+ years) 8,256,550: 43.0 (1.38) doi: 10.1126/scitranslmed.aaa0282. This article elaborates evidence supporting the hypothesis that topically delivered, inhaled antagonists of the calcium-sensing receptor (CaSR) have the potential to meet these requirements, and the practicality of repurposing existing, small molecule CaSR antagonists (calcilytics) for this purpose. Asthma afflicts more than 300 million people. Registered charity in England and Wales (326730), Scotland (SC038415) and the Isle of Man (1177). Would you like email updates of new search results?

The data are from national and state surveillance systems administered by the Centers for Disease Control and Prevention (CDC). This increases the secretion of parathyroid hormone (PTH), which has a temporary anabolic effect on bone tissue, producing an increase in both bone volume and bone density due to increased bone deposition and resorption. For people living with asthma or allergies, life can sometimes be difficult. Inhaled corticosteroids as combination therapy with beta-adrenergic agonists in airways disease: present and future. Asthma research is chronically underfunded; there have only been a handful of new treatments developed in the last 50 years so the importance of investment in research like this is absolutely essential.". 4 2015 Apr 22;7(284):284ra60. Calcilytics were first developed for the treatment of osteoporosis around 15 years ago with the aim of strengthening deteriorating bone by targeting CaSR to induce the release of an anabolic hormone. Medical care includes treatment of acute asthmatic episodes and control of chronic symptoms, including nocturnal and exercise-induced asthmatic symptoms. Professor Riccardi and her collaborators are now seeking funding to determine the efficacy of calcilytic drugs in treating asthmas that are especially difficult to treat, particularly steroid-resistant and influenza-exacerbated asthma, and to test these drugs in patients with asthma.

Areas covered: Although inhalers can manage … "Our paper shows how these triggers release chemicals that activate CaSR in airway tissue and drive asthma symptoms like airway twitchiness, inflammation, and narrowing. Overview. Asthma is a debilitating long-term condition which can cause coughing, wheezing, chest tightness and breathlessness. Calcilytics could provide the cure to asthma An international team of researchers believes it has made a life-changing breakthrough for the 300million sufferers worldwide and 5.4million in the UK. As-needed ICS-LABA in Mild Asthma: What Does the Evidence Say? A medicine to block the activation of CaSR could, potentially, prevent asthma attacks from occurring, thereby preventing the need for asthma rescue medicine. According to Cardiff University Professor Paul Kemp, who co-authored the study, the identification of CaSR in airway tissue means that the potential for treatment of other inflammatory lung diseases beyond asthma is immense. Crucially, the paper highlights the effectiveness of a class of drugs known as calcilytics in manipulating CaSR to reverse all symptoms associated with the condition. Relief me… Advertisement A team of scientists have for the first time identified the potential root cause of asthma and an existing drug that offers a new treatment. Recently we have shown that they can suppress airway hyperresponsiveness (AHR) and inflammation in asthma models, providing a potential for a novel asthma treatment strategy 1. "Using calcilytics, nebulized directly into the lungs, we show that it is possible to deactivate CaSR and prevent all of these symptoms."

Furthermore, no current anti-asthma drug targets bronchial smooth muscle hyperresponsiveness, a critical contributor to airways obstruction and the fundamental physiological abnormality characterizing asthma.  |  "For the first time we have found a link airways inflammation, which can be caused by environmental triggers - such as allergens, cigarette smoke and car fumes and airways twitchiness in allergic asthma. “Our findings point to an entirely novel pathophysiological mechanism in asthma. Dr Samantha Walker, Director of Research and Policy at Asthma UK, who helped fund the research, said: "This hugely exciting discovery enables us, for the first time, to tackle the underlying causes of asthma symptoms. Asthma is more common in adult women than adult men. Although clinically safe and well tolerated in people, calcilytics proved unsuccessful in treating osteoporosis. It is predicted that by 2020 these diseases will be the third biggest killers worldwide. But this latest breakthrough has provided researchers with the unique opportunity to re-purpose these drugs, potentially accelerating the time it takes for them to be approved for use asthma patients.
