Hayley Scott Bathroom scales, courtesy of Elinor D, Wikimedia Commons In this issue, two original papers, an excellent review by Dr Boulet (pp. 8-21) and an insightful editorial by Chapman and Salome (pp. 2-4), address various aspects of the link between obesity and asthma. The association between obesity and asthma is well established, but whether this is due to obesity causing symptoms through deconditioning and dysfunctional breathing or is due to a more direct and causal effect is not clear 1-9. The extent to which weight loss helps disease control is also not clear. Scott and colleagues (pp. 36-49) have shed light on this issue in a study in which dietary and exercise interventions were correlated with changes in airway inflammation. They demonstrated that a modest degree of weight loss over ten weeks in overweight and obese adults with asthma improved measures of both asthma quality of life and symptoms as well as the numbers of neutrophils and eosinophils in sputum. Further encouragement to focus on this aspect of management in our asthma clinics. Obesity and asthma: what can epidemiology tell us? Ed Mitchell Prevalence of overweight and obesity (combined) in children 13–14-year-old children in ISAAC centres. The obesity–asthma link is present in children as well as adults. Mitchell and colleagues (pp. 73-84) have taken advantage of the ISAAC database to further confirm this association as well as determine if it extends to other manifestations of allergic disease. Their study of over 76 000 children aged 6–7 years and over 200 000 adolescents, as well as showing a worrying global rate of obesity in children, confirmed the link between increased BMI and asthma and demonstrated that this extended to eczema, but not rhinitis. Excess television viewing (> 5 h) was also associated with asthma in both adults and children. Although this points to the importance of exercise in children, the authors also noted a link between allergic disease and vigorous exercise in adolescents but not the 6–7-year olds. This was also seen for eczema and rhinitis so this observation cannot be simply explained by exercise provoking exercise induced asthma. A case of epidemiology begging as many questions as it answers. Peach allergy: a new kid on the block Lisa Tuppo Peamaclein (Pru p 7) – A new risky, self-hiding, very stable peach allergenImage by Adriano Mari Severe food allergic reactions to peach are a common problem, particularly in Mediterranean. Pru p 3, a lipid transfer protein found mainly in the skin of the peach, is thought to be the major allergen involved. Tuppo and colleagues (pp. 128-140) explored the possibility that there are other important anaphylaxis causing allergens in peach, prompted by observations that some patients with allergic reactions to this fruit were negative to Pru p 3 in the ISAC 103 microarray. After much work, they have identified a new peach allergen which they have called Peamaclein which appears to be a member of a new family of proteins related to a potato antimicrobial peptide. The clinical importance of this allergen now needs to be fully characterized. References 1Agondi RC, Bisaccioni C, Aun MV, Ribeiro MR, Kalil J, Giavina-Bianchi P.
