BACKGROUND Sublingual-swallow immunotherapy was recently recognized in the World Health Organization Position Paper (Allergen immunotherapy: therapeutic vaccines for allergic diseases) "as a viable alternative to parenteral injection therapy to treat allergic diseases" in adults. More controlled studies were required to assess the efficacy and safety of(More)
Quantitative relations between dietary fat and cholesterol and plasma lipid concentrations have been the subject of much study and some controversy during the past 40 y. Previous meta-analyses have focused on the most tightly controlled, highest-quality experiments. To test whether the findings of these investigations are generalizable to broader(More)
BACKGROUND Asthma exacerbation is an episode of (sub)acute worsening of asthmatic symptoms. Exacerbation may depend on environmental factors. OBJECTIVE The present study investigated emergency calls for asthma exacerbation in children, analysing: i) their trend over the course of time; and ii) their possible relationship with environmental factors,(More)
BACKGROUND In children with asthma, discrepancies between objective indicators of airway obstruction and symptom perception are often observed. Although visual analogue scale (VAS) has been proposed as a useful tool for assessing accurate symptom perception, previous studies conducted in children with asthma included only small cohorts. A study was(More)
Guinea pigs were fed semipurified diets containing either 0% or 12.5% guar gum (GG) with 0.04% cholesterol or increasing concentrations of GG (0%, 2.5%, 5%, 7.5%, 10%, and 12.5%) with 0.25% cholesterol (by wt). Compared to the 0% GG diet with 0.04% cholesterol, intake of the 12.5% GG diet with 0.04% cholesterol lowered plasma low-density-lipoprotein (LDL)(More)
Guinea pigs were fed increasing concentrations of citrus pectin (CP) (0-12.5%, wt/wt) with low (LC, 0.04%) or high (HC, 0.25%) cholesterol. Animals fed LC diets had reduced plasma LDL concentrations with 10% and 12.5% CP and hepatic membrane apolipoprotein B/E receptor expression increased with high dosages of CP. Hepatic 3-hydroxy-3-methylglutaryl coenzyme(More)
Intercellular adhesion molecules (ICAMs), in particular ICAM-1, appear to play a crucial role in the recruitment and migration of inflammatory cells to the site of an allergic reaction. Glucocorticoids and allergen-specific immunotherapy have been shown to exert effects on selected components of this system, both in vitro and in vivo, but further research(More)
UNLABELLED Bacillus clausii has been demonstrated to exert some immunomodulatory activities and to be safe. Allergic subjetcs show Th2 polarization and defect of T regulatory cells. Aim of the study was to investigate whether Bacillus clausii administration in allergic subjects might modulate cytokine pattern. Ten subjects (mean age 22.3 years) suffering(More)
BACKGROUND Nowadays, the measure of the fractional concentration of exhaled nitric oxide (FeNO) enables to assess airway inflammation during an office visit and there is international consensus on this testing methodology. The aim of this study was to evaluate whether FeNO measurement is predictable for bronchial hyperreactivity (BHR) in children with(More)
BACKGROUND Chronic rhinosinusitis is frequently associated with asthma. A Th2 cytokine pattern has been recently reported in chronic rhinosinusitis in asthmatic children. OBJECTIVE To evaluate the effects of treating concomitant chronic rhinosinusitis on respiratory symptoms and function and immunopathological parameters in asthmatic children. METHODS(More)
