Show moreIn this thesis, we focussed on the management of obese patients with asthma. Based on the available knowledge about the obesity and asthma relationship, and the effects of different weight loss interventions in obese asthmatics, we defined the following aimsfor this thesis:1. To gain insight in the effects of exercise training in obese asthmatics and to determine the feasibility and effects of high intensity training in obese subjects2. To design a pulmonary rehabilitation program for obese patients with suboptimalcontrolled asthma and to determine the effectiveness of this program in a randomized controlled trial3. To improve our knowledge on the pathophysiology of obesity related asthma4. To gain insight in the risks and long-term effects of bariatric surgery in morbidlyobese subjects with asthma. Show less

Show moreChildhood obesity is an increasing health issue. In the first part of this thesis comorbidities in children with obesity were studied, concerning the diagnostic process and dosing regimens. In children with obesity and respiratory symptoms the diagnosis of asthma was studied and in children with ADHD dosing regimens. Overtreatment as a consequence of overdiagnosis was frequently observed in children with obesity and asthma and undertreatment due to relative underdosing in the ADHD population with obesity. This highlights the necessity for accurate diagnostic processes alongside dosing regimens based on pharmacokinetic changes caused by obesity. The focus in the second part of this thesis was on screening for complications of obesity namely insulin resistance and cardiovascular diseases. Given the high prevalence of insulin resistance and the observed changes of cardiovascular parameters, screening on cardiometabolic complications is warranted in all children with obesity. Pharmacological treatment with metformin in addition to lifestyle intervention was studied in the last part of this thesis. Given the favorable effect on BMI in children and adults and the maintenance of weight loss and reduction in progression towards T2DM in adults, metformin can be considered in children with obesity and insulin resistance in addition to lifestyle intervention.
