Couple Of Thoughts Around The actual Forthcoming Future For Flavoprotein

Another study showed a negative association between BMI and eNO in overweight and obese patients with asthma, independent of corticosteroid use [43]. The study [43] included patients with difficult to treat asthma and is in agreement with the above data. The body mass index was negatively associated with exhaled nitric oxide values even after adjusting for the corticosteroid dose [33]. It has been hypothesized that high levels of proinflammatory molecules released from adipose tissue into blood stream could influence airway inflammation thereby increasing the prevalence and the severity of asthma in obese patients. The findings of less severe airway inflammation in obese patients suggest that the mechanical Rapamycin clinical trial effect of the amount of abdominal adipose tissue on the lung function and co-morbid factors could make them more symptomatic and difficult to treat. Presumably, mechanisms other than cellular and endothelial airway inflammation are involved in the relationship between asthma symptoms and obesity. Atopy is an important risk factor in the development of allergic asthma. Recent data indicate the relation of higher body mass index with increased prevalence of atopy [44]. Other studies describe a lack of relation between mean serum IgE level and blood eosinophil percentage with obesity in asthmatics [32?and?33]. The airway responsiveness did not differ between these two groups neither [33]. There are, however, some opposite studies. Ciprandi et al. [8] found a clear relation between methacholine airway responsiveness ABT-263 cell line and BMI among patients with asthma. BMI was significantly higher Flavoprotein in patients with PD20 values <100 ��g (mean BMI = 27.9) with respect to patients with PD20 values between 100 and 350 ��g (mean BMI = 25.3). However, there was no association between the percentage of overweight/obese patients and mono- or polysensitization [8]. Additionally, in the latest study performed on asthmatic obese and non-obese patients, no association was found between positive skin prick test and obesity [45]. Regarding sex differences, the trend towards a positive association between body fat percentage and positive skin prick tests was found only in women [15]. In summary, the studies on the association between adiposity and atopy have conflicting results and the issue needs to be investigated in the future. Possible confirmation of the relationship between obesity and atopy may indicate the biologically active role of fat tissue rather than a mechanical one. Obesity decreases lung volume and increases airway resistance inducing symptoms that could mimic asthma. Subjects with obesity claim more wheeze and shortness of breath which may be due to the increased work of breathing and deconditioning [11]. In the obese, the functional residual capacity (FRC) is reduced because of the changes in the elastic properties of the chest wall.
