The Gene-Environment Interactions in Respiratory Diseases (GEIRD) Project.
2009
The role of genetic and environmental factors, as well as their interaction, in the natural history of asthma, allergic rhinitis and chronic obstructive pulmonary disease (COPD) is largely unknown. This is mainly due to the lack of large-scale analytical epidemiological/genetic studies aimed at investigating these 3 respiratory conditions simultaneously. The GEIRD project is a collaborative initiative designed to collect information on biomarkers of inflammation and oxidative stress, individual and ecological exposures, diet, early-life factors, smoking habits, genetic traits and medication use in large and accurately defined series of asthma, allergic rhinitis and COPD phenotypes. It is a …
Measurement of inflammatory mediators of mast cells and eosinophils in native nasal lavage fluid in nasal polyposis.
2001
<i>Background:</i> Nasal polyposis (NP) often coexists with asthma, rhinitis and sinusitis. Polyp histology typically shows chronic, eosinophilic inflammation. The inflammatory cell infiltrate generally includes eosinophils, lymphocytes, plasma cells and mast cells. <i>Objective:</i> To gain insight into the natural history of NP, we analysed mediator levels and leukocyte values in nasal fluids and eosinophil cationic protein (ECP), total IgE levels and eosinophils in the blood in several groups of both allergic and non-allergic patients with nasal polyps and in patients with allergic rhinitis (AR). <i>Methods:</i> Thirty-two patients with nasal polyps en…
Noninvasive methods for the detection of upper and lower airway inflammation in atopic children
2006
Background Exhaled nitric oxide (FE NO ) and exhaled breath condensate (EBC) are noninvasive methods to assess inflammation. Objective To investigate the role of the FE NO and of the EBC pH and IL-5 levels in atopic children. Methods We evaluated oral and nasal FE NO and the pH and IL-5 of oral and nasal EBC in children with atopic dermatitis (AD; n=18), allergic rhinitis (AR; n=18), intermittent asthma (n = 21), moderate persistent asthma (n = 18), and healthy controls (HCs; n=16). Results Oral FE NO was significantly increased in asthma, whereas the nasal values were increased in AR and asthma in comparison with HCs. The pH of oral EBC was lower in AD and asthma than in AR and HCs, wherea…
Changes of arterial hemodynamics in patients with type 2 diabetes mellitus or impaired glucose tolerance
2006
Aim: The aim of our study was to evaluate the arterial hemodynamics in patients with type 2 diabetes mellitus or impaired glucose tolerance without clinical or Doppler evidence of peripheral arterial disease, in order to early detect vascular damage. Methods. We studied 20 subjects (12 men and 8 women, aged between 48 and 62 years) with type 2 diabetes mellitus (Group 1), 20 subjects (11 men and 9 women, aged between 49 and 61 years) with reduced glucose tolerance (Group 2), and 20 normal subjects (10 men and 10 women, aged between 48 and 62 years) (Group 3). Each subject underwent strain-gauge plethysmography and the following parameters were evaluated: rest flow (RF); peak flow (PF); PF/R…
The Effect of Intranasal Corticosteroids on Asthma Control and Quality of Life in Allergic Rhinitis with Mild Asthma
2011
BACKGROUND: The mechanisms through which rhinitis affects asthma have not been completely elucidated. We explored whether the effect of nasal treatment on asthma control and respiratory-related quality of life (HRQoL) is mediated by inflammatory changes of the upper and lower airways. METHODS: Allergic rhinitics with mild asthma were randomized to a 14-day treatment period with either nasal budesonide 100 mug, 1 puff per nostril twice a day, or placebo. Clinical, functional, and biological evaluations were performed before and after treatment. RESULTS: Twenty subjects (M/F: 10/10; age: 31 +/- 15 years; mean +/- SD) were enrolled, and a total of 17 individuals completely participated in the …
Nasal budesonide efficacy for nasal nitric oxide and nasal obstruction in rhinitis
2017
Nasal nitric oxide (nNO) is a noninvasive tool that may be helpful in evaluating the inflammatory status in the upper airways [1]. Previous studies report that nNO is elevated in children with Allergic Rhinitis (AR) [2], especially in perennial sensitized subjects [3], and that it may be affected by topical administration of intranasal steroids (INSs) [4].

Efficacy and tolerability of preservative-free eye drops containing a fixed combination of dorzolamide and timolol in glaucoma patients.
2010
To evaluate the efficacy and tolerability of preservative-free eye drops (dorzolamide/timolol) in routine management of preservative-sensitive glaucoma patients.Data from 2,298 glaucoma patients requiring intraocular pressure (IOP) reduction and suffering from intolerance to benzalkonium chloride or active agents of previously used eye drops were valid for baseline and safety analysis in this prospective, open, noncomparative, multicenter, noninterventional study. Patients were treated with preservative-free dorzolamide/timolol eye drops for 12 weeks. Main efficacy endpoint was IOP reduction after 12 weeks of treatment. Two thousand forty-nine patients were considered for efficacy analysis.…
Switching from a preserved to a preservative-free prostaglandin preparation in topical glaucoma medication.
2010
. Purpose: The purpose of this study was to investigate the tolerability and intraocular pressure (IOP) reducing effect of the first preservative-free prostaglandin tafluprost (Taflotan®) in patients exhibiting ocular surface side-effects during latanoprost (Xalatan®) treatment. Methods: A total of 158 patients were enrolled in this open-label multicentre study. Eligible patients had to have at least two ocular symptoms, or one sign and one symptom, during treatment with latanoprost. At baseline, the patients were directly switched from latanoprost to preservative-free tafluprost for 12 weeks. The patients were queried for ocular symptoms, and ocular signs were assessed by using tear brea…
Thermal hypoaesthesia differentiates secondary restless legs syndrome associated with small fibre neuropathy from primary restless legs syndrome.
2010
This study aimed to assess thermal and mechanical perception and pain thresholds in primary idiopathic restless legs syndrome and secondary restless legs syndrome associated with small fibre neuropathy. Twenty-one patients (age: 53.4 + or - 8.4, n = 3, male) with primary restless legs syndrome and 13 patients (age: 63.0 + or - 8.2, n = 1, male) with secondary restless legs syndrome associated with small fibre neuropathy were compared with 20 healthy subjects (age: 58.0 + or - 7.0; n = 2, male). Differential diagnosis of secondary restless legs syndrome associated with small fibre neuropathy was based on clinical symptoms and confirmed with skin biopsies in all patients. A comprehensive quan…
Branch Retinal Vein Occlusion Followed by Central Retinal Artery Occlusion in Churg-Strauss Syndrome: Unusual Ocular Manifestations in Allergic Granu…
2009
Purpose To describe a rare branch retinal vein occlusion (BRVO) followed by central retinal artery occlusion (CRAO) in a patient with Churg-Strauss syndrome (CSS). Methods A 55-year-old man with a not yet diagnosed CSS developed a BRVO in the left eye and 1 year later a CRAO with painless and acute vision loss in the same eye. Medical history included bronchial asthma, history of allergy, eosinophilic pneumonia, bilateral pleuric and pericardial effusion, hypereosinophilia, and purpuric vasculitis. Results CRAO in the left eye was diagnosed by retinal whitening and a cherry red spot with coexisting old BRVO evidenced by previous laser photocoagulation. Corticosteroids and cyclophosphamide t…
