BACKGROUND Allergic rhinitis and asthma comorbidity is supported by both the similar underlying pathogenesis and immunologic mechanisms. The aim of this study was to verify whether the characteristics of rhinitis classified according to the new Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines correlate with the prevalence of asthma. METHODS(More)
BACKGROUND The aim of our study was to assess the prevalence of rhinitis, sneezing, runny or blocked nose apart from colds in a pre-school children population and to evaluate the risk factors and relationship with allergic diseases and sensitization. METHODS Eighteen nursery schools were randomly selected. The International Study of Asthma and Allergies(More)
INTRODUCTION The Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines provide a stepwise treatment to rhinitis, which classifies the disease according to its duration and severity. OBJECTIVES The aim of the study was to verify whether these variables influence drug prescriptions for rhinitis and asthma. METHODS A multi-centre cross-sectional(More)
A cross-sectional study was conducted on among 28,856 children aged from birth to 14 years to determine the prevalence of asthma and assess its treatment in a sample of asthmatic children. Children diagnosed with asthma were identified by a sensitive algorithm applied to the information stored in the computerized medical records between 1997 and 1998.(More)
Transforming growth factor (TGF)-beta may play a significant role in nasal polyposis pathogenesis, possibly through fibroblast activation. We studied the effects of two TGF-beta isoforms (TGF-beta1 and TGF-beta2) on nasal polyposis fibroblasts by evaluating cell proliferation and differentiation into myofibroblasts. In addition, the inhibitory activity of(More)
BACKGROUND Macular oedema tends to be a more rapid complication of diabetic retinopathy and represents the major cause of blindness. Among subjects with type 2 diabetes mellitus, it can be found in 15% of those who use insulin and 4% of those who do not. Use of thiazolidinediones (glitazones) has recently been associated with some cases of macular oedema.(More)
Summary beta2-adrenoreceptor agonists are able to modulate various aspects of airway cell functions involved in the inflammatory and repair processes characterizing a variety of respiratory disorders. Human bronchial epithelial cells (HBECs), which can act as immune effector cells and express beta2-adrenoreceptors, were used to test the effects of different(More)
OBJECTIVE The QUASAR (Quality Assessment Score and Cardiovascular Outcomes in Italian Diabetes Patients) study aimed to assess whether a quality-of-care summary score predicted the development of cardiovascular (CV) events in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS In 67 diabetes clinics, data on randomly selected patients were(More)
In asthma a dysregulation of eosinophil apoptosis and an imbalance of metalloproteinase-9 (MMP-9) and tissue inhibitor metalloproteinase-1 (TIMP-1) play an important role in airway inflammation and remodelling. We evaluated the effects of a low dose of inhaled fluticasone proprionate (FP) (100 microg bid by Diskus) for 4 weeks in 24 steroid naive patients(More)
BACKGROUND Topical corticosteroids are beneficial in the treatment of allergic respiratory disorders; they exert effects on a number of cells involved in allergic inflammatory reactions. On the other hand, major histocompatibility complex (MHC)-unrestricted cytotoxicity (i.e., natural killer [NK] cell activity) may play a role in the inflammatory allergic(More)
