Obstructive sleep apnea and chronic kidney disease: open questions on a potential public health problem
2018
To determine the relationship between obstructive sleep apnea (OSA) and chronic kidney disease (CKD). Previous population studies of the association are sparse, conflicting and confined largely to studies of administrative data.Cross-sectional analysis in unselected participants of the Men Androgens Inflammation Lifestyle Environment and Stress (MAILES) study, aged40 years. Renal data were available for 812 men without a prior OSA diagnosis who underwent full in-home polysomnography (Embletta X100) in 2010-2011. CKD was defined as an estimated glomerular filtration rate (eGFR)60 mL/min/1.73m2 or eGFR≥60 and albuminuria (albumin-creatinine ratio ≥3.0 mg/mmol).CKD (10.5%, n = 85 [Stage 1-3, 9…
Reticulocytes in untreated obstructive sleep apnoea.
2008
Background and Aim. The short, repetitive hypoxaemic episodes observed in obstructive sleep apnoea (OSA) may determine small augmentations in mature red blood cells. It is unknown whether they affect reticulocyte release. This study explored whether the number and degree of maturation of circulating reticulocytes may be altered in OSA, possibly through the effect of erythropoietin. Methods. Fifty male adult patients with suspected OSA, normoxic during wakefulness, were studied. After nocturnal polysomnography, a blood sample was withdrawn for blood cells count, erythropoietin, iron and transferrin determination. Reticulocyte concentration and degree of immaturity [high (H), medium (M), or l…
Chronic rhinosinusitis with nasal polyps impact in severe asthma patients: Evidences from the Severe Asthma Network Italy (SANI) registry
2020
Abstract Background The clinical and laboratory features of patients enrolled in the Severe Asthma Network in Italy (SANI) registry, a web-based observatory collecting demographic, clinical, functional and inflammatory data of patients with severe asthma were evaluated, with a special emphasis to chronic rhinosinusitis with nasal polyposis (CRSwNP). Methods For each eligible patients the following information has been collected: demographic data, clinical features, asthma control in the previous month according to the GINA (Global INitiative for Asthma) Guidelines and standardized questionnaires, concomitant regular and on demand treatments and inflammatory markers. Results 695 patients wit…
Recommendations for the management of patients with obstructive sleep apnoea and hypertension.
2013
This article is aimed at addressing the current state-of-the-art in epidemiology, pathophysiology, diagnostic procedures and treatment options for appropriate management of obstructive sleep apnoea (OSA) in cardiovascular (in particular hypertensive) patients, as well as for the management of cardiovascular diseases (in particular arterial hypertension) in OSA patients. The present document is the result of work performed by a panel of experts participating in the European Union COST (Cooperation in Scientific and Technological research) Action B26 on OSA, with the endorsement of the European Respiratory Society and the European Society of Hypertension. In particular, these recommendations …
Airway distensibility by HRCT in asthmatics and COPD with comparable airway obstruction.
2013
Introduction: Decreased airway distensibility (AD) in response to deep inspirations, as assessed by HRCT, has been associated with the severity of asthma and COPD. Aims: The current study was designed to compare the magnitude of AD by HRCT in individuals with asthma and COPD with comparable degrees of bronchial obstruction, and to explore factors that may influence it. Results: We enrolled a total of 12 asthmatics (M/F:7/5) and 8 COPD (7/1) with comparable degree of bronchial obstruction (FEV1% predicted mean±SEM: 69.1 ± 5.2% and 61.2 ± 5.0%, respectively; p = 0.31). Each subject underwent chest HRCT at FRC and at TLC. A total of 701 airways (range 20 to 38 airway per subject; 2.0 to 23.1 m…
Sleep, sleep-disordered breathing and metabolic consequences.
2009
Sleep profoundly affects metabolic pathways. In healthy subjects, experimental sleep restriction caused insulin resistance (IR) and increased evening cortisol and sympathetic activation. Increased obesity in subjects reporting short sleep duration leads to speculation that, during recent decades, decreased sleeping time in the general population may have contributed to the increasing prevalence of obesity. Causal inference is difficult due to lack of control for confounders and inconsistent evidence of temporal sequence. In the general population, obstructive sleep apnoea (OSA) is associated with glucose intolerance. OSA severity is also associated with the degree of IR. However, OSA at bas…
Cardiovascular Events in Moderately to Severely Obese Obstructive Sleep Apnea Patients on Positive Airway Pressure Therapy.
2016
<b><i>Background:</i></b> In moderately to severely obese patients with obstructive sleep apnea (OSA), the effects of long-term positive airway pressure (PAP) treatment on cardiovascular risk are poorly defined. <b><i>Purpose:</i></b> To assess the effect of continuous positive airway pressure (CPAP) or noninvasive ventilation (NIV) on the occurrence of cardiovascular events in obese OSA patients. <b><i>Methods:</i></b> We performed a noninterventional observational study in obese OSA patients recruited between 2007 and 2010 at the Sleep Center, University of Grenoble, treated with CPAP or NIV, and followed for 5.6 year…
Healthcare costs of the SATisfaction and adherence to COPD treatment (SAT)study follow-up
2019
Abstract Background Chronic obstructive pulmonary disease (COPD) is characterised by recurring exacerbations. We estimated the costs of healthcare resources for COPD management funded by the Italian National Healthcare Service (INHS) for one year. Methods We examined the demographic, clinical, and economic variables at enrolment and follow-up visits (at 6 and 12 months) of COPD patients participating in the SAT study and referred to 20 Italian pulmonary centres with different institutional characteristics. Costs were expressed in Euro (€) 2018. A random effects log-linear panel regression model was performed to predict the average cost per patient. Results Most of the centres were public in…
Revising old principles of inhaled treatment in new fixed combinations for asthma.
2015
The major influencing factors on persistent asthma control are the selected treatment(s), the drug delivery route and patient's adherence to therapy, together with the influence of lifestyle (i.e. sedentary habit), comorbid conditions and specific asthma phenotypes. Inhaled corticosteroids (ICS) in combination with a long-acting β2-agonist (LABA) are the gold standard for management of persistent asthma, with maximal local targeting and minimal systemic side effects. Several innovative inhaler devices have been developed for effective local drug administration and good patient compliance to therapy. Recently, a new ICS/LABA fixed combination, formulated with fluticasone propionate (FP) and …
Does the frequency of switching inhalers represent a predictive factor of exacerbation in asthma?
2020
Objective: Management of asthma includes monitoring of inhaler technique and level of adherence to treatment. Both factors could be influenced by high frequency of switching inhaler devices. We explored whether switching inhalers is an independent predictive factor of exacerbations. Methods: Data were collected from 2015 to 2017 from the outpatient clinic of asthma at the University of Palermo, Italy. This observational study consisted of two phases: Phase 1 included subjects of at least three visits in the previous year who reported the frequency of inhalers switched; Phase 2 included subjects of at least two visits during the second year, and the rate of switches and exacerbations was rec…
