Asthma is a common condition with different types recognised that have variable responses to current treatments. It is often poorly controlled and there is a need to discover new treatments. Obesity is common in asthma and is associated with increase in symptoms, poorer asthma control and quality of life, and increased healthcare utilisation and treatment burden. The Counterweight Plus programme is a safe, evidence-based non-surgical intervention that is associated with sustained weight losses of up to 15% in obese individuals but its effects in asthma have not been tested. Our study aims to evaluate the impact of this intervention in individuals with difficult asthma associated with obesity.\n\nThe Counterweight Plus programme includes a total diet replacement (TDR) phase (12 weeks) followed by structured food reintroduction (6 weeks) and long term weight loss maintenance (34 weeks) and will be provided by Dieticians trained in the delivery of this intervention. Participants will attend fortnightly clinic reviews with Dieticians during the first 18 weeks and then monthly clinic reviews during the weight loss maintenance period.\n\nParticipants will be randomised to Counterweight Plus programme or usual care (control) and followed for 1 year with study visits at baseline, 4 months and 1 year. During study visits participants will be invited to complete questionnaires, provide a blood sample, perform breathing tests and a walking test, and wear an activity monitor for one week.\n\nIf the Counterweight Plus programme is proven to be of benefit in this patient group, this may lead to service development so that this intervention may be made available to similar patients in the future within the clinical setting.', 'detailedDescription': "This study will be a unblinded, pragmatic, pilot, randomised, controlled trial of the Counterweight Plus programme versus usual care in individuals with difficult asthma associated with obesity. Eligible individuals will be identified through Difficult Asthma Clinics or ward admissions. Those wishing to participate will receive an information sheet and be invited to provide written informed consent prior to commencing the study.\n\nBaseline Visit\n\nMeasurements taken at the baseline visit will include:\n\nDemographics - age, gender, smoking history (current, ex, none, years since stopped, pack years), age at asthma diagnosis, duration of asthma, atopy, co-morbidities (allergic/perennial rhinitis, nasal polyps, nasal surgery, eczema, gastro-oesophageal reflux disease, diabetes, hypertension, cardiac disease, osteopenia/osteoporosis etc), medications (inhaled/nebulised short acting beta2-agonists (SABA), inhaled and oral corticosteroids etc), healthcare usage (oral corticosteroid (OCS) boosts, unscheduled General Practitioner (GP) or Accident + Emergency (A+E) attendances, hospital and Intensive Care Unit (ICU) admissions in preceding year), weight, height and BMI.\n\nQuestionnaires - Medical Research Council (MRC) dyspnoea scale, Asthma Control Questionnaire (ACQ6), Asthma Quality of Life Questionnaire (AQLQ), and Hospital Anxiety and Depression Scale (HAD).\n\nVenepuncture - full blood count, urea and electrolytes, liver function tests, magnesium, bone profile, insulin, glucose, HbA1c, lipids, C-reactive Protein (CRP), Interleukin-6 (IL-6), leptin and adiponectin Lung Function/inflammometry - peak expiratory flow (PEF) (best of 3), Spirometry (pre- and post-bronchodilator), Fraction of exhaled nitric oxide (FENO) Exercise tolerance - 6 minute walk test (practice test and repeat test)\\[29\\], Modified Borg Dyspnoea Scale, pulse oximetry.\n\nPhysical Activity - actigraphy. Participants will be given the Actigraph device and asked to wear it continuously for 7 days on their non-dominant wrist, then hand it back.\n\nParticipants will be provided with a Personalized Asthma Management Plan, and Symptoms Diary that includes SABA use and other healthcare usage (oral corticosteroid (OCS) boosts, unscheduled GP or A+E attendances, hospital and ICU admissions); inhaler technique will be corrected if necessary.\n\nParticipants will be randomized 1:1 to Group A and Group B. Group A will enter the Counterweight Plus programme and Group B will enter the usual care arm.\n\nParticipants will return for Visit 2 at 16 weeks and Visit 3 at 52 weeks.\n\nMeasurements taken at Visits 2 and 3 will include:\n\nDemographics - medications (inhaled/nebulised short acting beta2-agonists (SABA), inhaled and oral corticosteroids etc), healthcare usage (oral corticosteroid (OCS) boosts, unscheduled GP or A+E attendances, hospital and ICU admissions since last visit), weight, height, and BMI.\n\nQuestionnaires - MRC dyspnoea scale, Asthma Control Questionnaire (ACQ6), Asthma Quality of Life Questionnaire (AQLQ), and Hospital Anxiety and Depression Scale (HAD).\n\nVenepuncture - full blood count, urea and electrolytes, liver function tests, magnesium, bone profile, insulin, glucose, HbA1c, lipids, CRP, IL-6, leptin and adiponectin Lung Function/inflammometry - PEF (best of 3), Spirometry (pre- and post-bronchodilator), Fraction of exhaled nitric oxide (FENO) Exercise tolerance - 6 minute walk test, Modified Borg Dyspnoea Scale, pulse oximetry.\n\nPhysical Activity - actigraphy Visits will be postponed by 4 weeks in the event of exacerbation or respiratory infection. Throughout the study period changes to asthma medications will be allowed as clinically indicated.\n\nRescue Package for weight regain or re-emergence of diabetes Some patients find weight maintenance difficult, some relapse temporarily and gain weight rapidly. Others may tend to let things slip more gradually. Pilot studies showed the value of a sympathetic, but firm approach to relapse/regain management. If weight regains occurs in TDR randomised participants, or if diabetes is found to have returned (HbA1c risen above 6.5%) at any time during the 18 month weight loss maintenance stage, 'rescue plans' for weight gain prevention will be offered.\n\n1. Weight regain of \\>2kg: offer the use of TDR to replace one main-meal per day for 4 weeks, and offer orlistat 120 mg tid, with each meal.\n2. Weight gain of \\>4kg, or to \\<15kg below starting weight or if diabetes recurs: offer 4 weeks TDR with fortnightly weekly practice nurse/dietitian review and then a 2-4 week food re-introduction (adding 1 meal/week as before). Lowfat dietary advice and physical activity will be reinforced for weight maintenance and orlistat treatment will be offered.\n\nThis package can be repeated as required in each year of the maintenance phase."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
