MUC1-CT mediates corticosteroid responses in COPD
2016
Background: Corticosteroid resistance is an acquired condition in chronic obstructive pulmonary disease (COPD) patients and a challenge to develop new anti-inflammatory therapies. In previous reports we showed that cytoplasmic tail of the membrain tethered mucin 1 (MUC1-CT) interacts with glucocorticoid receptor (GR) mediating corticosteroid anti-inflammatory efficacy. Objectives: To analyze the role of MUC1-CT as a key marker of corticosteroid efficacy in COPD Methods: The expression of MUC1-CT and the anti-inflammatory role of dexamethasone were evaluated in neutrophils and bronchial epithelial cells from healthy and COPD patients. Anti-inflammatory effects of dexamethasone and glucocorti…
Oral CorticoSteroid sparing with biologics in severe asthma: A remark of the Severe Asthma Network in Italy (SANI)
2020
According to the data derived from several national and international registries, including SANI (Severe Asthma Network Italy), and considering the strong impact that frequent or regular use of oral corticosteroid has on quality of life (QoL) of severe asthmatics, as well as on the costs for managing corticosteroid-related diseases, oral corticosteroid sparing up to withdrawal should be considered a primary outcome in the management of severe asthma. New biologics have clearly demonstrated that this effect is possible, with concomitant reduction in the rate of exacerbations and in symptom control. Then, there is no reason for using so frequently oral corticosteroid before having explored al…
First clinical uterus transplantation trial: a six-month report.
2014
Objective To report the 6-month results of the first clinical uterus transplantation (UTx) trial. This type of transplantation may become a treatment of absolute uterine-factor infertility (AUFI). Design Prospective observational study. Setting University hospital. Patient(s) Nine AUFI women and their live uterine donors, the majority being mothers. Intervention(s) Live-donor UTx and low-dose induction immunosuppression. Main Outcome Measure(s) Data from preoperative investigations, surgery and follow-up for 6 months. Result(s) Durations of donor and recipient surgery ranged from 10 to 13 hours and from 4 to 6 hours, respectively. No immediate perioperative complications occurred in any of …
Non-neuronal cholinergic system contributes to corticosteroid resistance in chronic obstructive pulmonary disease patients
2016
Background: Inhaled corticosteroid (ICS) with long-acting beta-2 agonists is a well-documented combination therapy for chronic obstructive pulmonary disease (COPD) based on its additive anti-inflammatory properties. By contrast, the recommendation of ICS in combination with long-acting muscarinic antagonist (LAMA) is not evidence-based. In this study, neutrophils obtained from COPD patients were used to compare the anti-inflammatory effects of aclidinium bromide (a long-acting muscarinic antagonist) with corticosteroids and their potential additive effect. Methods: Human sputum and blood neutrophils were isolated from healthy individuals ( n = 37), patients with stable COPD ( n = 52) and th…
Inter-society consensus for the use of inhaled corticosteroids in infants, children and adolescents with airway diseases
2021
Abstract Background In 2019, a multidisciplinary panel of experts from eight Italian scientific paediatric societies developed a consensus document for the use of inhaled corticosteroids in the management and prevention of the most common paediatric airways disorders. The aim is to provide healthcare providers with a multidisciplinary document including indications useful in the clinical practice. The consensus document was intended to be addressed to paediatricians who work in the Paediatric Divisions, the Primary Care Services and the Emergency Departments, as well as to Residents or PhD students, paediatric nurses and specialists or consultants in paediatric pulmonology, allergy, infecti…
Hemin, an inducer of heme oxygenase-1, lowers intraocular pressure in rabbits.
2007
Carbon monoxide (CO) generated from heme may induce vasodilation and exert cyto-protective properties in the eye. This study was undertaken to investigate the effects of hemin, a potent inducer of heme oxygenase-1 (HO-1), on models of ocular hypertension in rabbits.Ocular hypertension was induced by injecting alpha-chymotrypsin in both eyes under local anesthesia. Only rabbits with an intraocular pressure (IOP) of 25 mmHg or more were used. The dose-response study of the hemin effect on IOP was made by an intravenous injection of the drug (50, 75, and 100 mg/kg) and subsequent IOP monitoring every 6 h. A separate set of animals was pretreated with the HO-1 inhibitor, zinc protoporphyrin-IX …
Chronic Obstructive Pulmonary Disease Lung Microbiota Diversity May Be Mediated by Age or Inhaled Corticosteroid Use
2015
We read with great interest the paper by Garcia-Nunez et al. ([1][1]) published in the December 2014 issue of this journal, where the authors investigated the sputum microbiota of chronic obstructive pulmonary disease (COPD) patients. The authors found decreased microbial diversity in patients with
Efficacy of posaconazole and amphotericin B in experimental invasive pulmonary aspergillosis in dexamethasone immunosuppressed rats
2007
Objectives: Invasive pulmonary aspergillosis is associated with high mortality. To assess new antifungal therapy options, animal models have to be developed to assess, in an appropriate setting, the activity of new drugs. Methods: Male albino CD rats (125–150 g) were fed with a protein-free diet and received dexamethasone thrice weekly subcutaneously during the whole experiment. After 2 weeks, an inoculum of 10 6 conidia of Aspergillus fumigatus (H11-20) was injected intratracheally. Antifungal treatment was initiated and continued for a total of 7 days. Animals were grouped in numbers of 10. One group of animals served as untreated control, whereas the others were treated with amphotericin…
Efficacy of methylprednisolone on pain, trismus and quality of life following surgical removal of mandibular third molars: a double-blind, split-mout…
2021
Background The objective of the present study was to compare the efficacy of different doses of methylprednisolone on postoperative sequelae and quality of life (QoL) following surgical removal of mandibular third molars (SRM3). Material and Methods Fifty-two patients (16 men and 36 women, mean age 25.9 years, range: 18-39) with bilateral impacted mandibular third molars were randomly allocated into intraoperative muscular injection of either 20mg, 30mg, 40mg methylprednisolone or saline injection. Baseline measurements were obtained preoperatively and compared with assessment after one day, three days, seven days and one month. Pain and trismus were estimated by visual analog scale score a…
Mepolizumab effectiveness on small airway obstruction, corticosteroid sparing and maintenance therapy step-down in real life
2020
Background: Mepolizumab (MEP) has been recently introduced to treat severe eosinophilic asthma. Trials have demonstrated a significant effectiveness in this asthma phenotype. We evaluated MEP efficacy on lung function, symptoms, asthma exacerbations, biologic markers, steroid dependence and controller treatment level in real-life. Methods: We retrospectively analyzed 134 severe asthmatics (61 males; mean age 58.3 ± 11; mean FEV1%:72 ± 21), treated with MEP for at least 6 months (mean duration:10.9 ± 3.7 months). Results: FEV1% improved significantly after MEP. Mean FEF25-75 also increased from 37.4 ± 25.4% to 47.2 ± 27.2% (p < 0.0001). Mean baseline blood eosinophil level was 712 ± 731/μ…
