Fractional exhaled nitric oxide is associated with more severe asthma
2018
Fractional exhaled nitric oxide (FeNO) levels are used as a marker of airway inflammation. The aim of the present work was to evaluate a possible relationship between FeNO and parameters of asthma control and severity in different asthma phenotypes. FeNO was evaluated in 200 asthma patients (37% male, mean age ± SD 54±15 years, 19% controlled (GINA), 30% treated with oral corticosteroids (OCS), median FEV1 (interquartile range) 2,05 L (1,49-2,70), 74% pred. (56-90%)), together with other asthma characteristics (lung function, asthma control, allergies, serum IgE, serum ECP, and blood eosinophils). Patients with poorly controlled asthma had significantly higher FeNO values (ACQ-5≥1.5 vs. 70%…
Cost-effectiveness of switching from omalizumab to mepolizumab in uncontrolled severe eosinophilic asthma
2020
Background: Severe asthma is burdened by frequent exacerbations and use of oral corticosteroids (OCS) which worsen patients’ quality of life and increased healthcare spending. Objectives: To assess the clinical and economic impact of switching from omalizumab (OMA) to mepolizumab (MEP) in patients eligible for both biologics but not optimally controlled with OMA. Methods: Uncontrolled patients referred to 6 asthma clinics in south of Italy switched from OMA to MEP, were enrolled and followed-up to Jan 2020. Clinical information included blood eosinophil count, asthma control test (ACT), pulmonary function, IgE, exhaled nitric oxide (FeNO), OCS intake, drugs, exacerbations/hospitalizations, …
Murine genetic deficiency of neuronal nitric oxide synthase (nNOS-/-) and interstitial cells of Cajal (W/Wv): Implications for achalasia?
2014
Background and aim Nitric oxide (NO) is an important inhibitory mediator of esophageal function, and its lack leads to typical features of achalasia. In contrast, the role of intramuscular interstitial cells of Cajal (ICC-IM) and vasoactive intestinal peptide (VIP) in lower esophageal sphincter (LES) function is still controversial. Therefore, we examined the function and morphology of the LES in vivo in NO-deficient (nNOS(-/-) ), ICC-IM-deficient (W/W(v) )-, and wild-type (WT) mice. Methods Esophageal manometry was performed with a micro-sized transducer catheter to quantify LES pressure, swallow evoked LES relaxation, and esophageal body motility. The LES morphology was examined by semiqu…
Inhaled nitric oxide as a rescue therapy in a preterm neonate with severe pulmonary hypertension: a case report
2018
Abstract Background Inhaled nitric oxide (iNO) has been approved for the treatment of persistent pulmonary hypertension of the newborn (PPHN) in term and near-term newborns. Its role in the management of persistent pulmonary hypertension in preterm infants is not clear. Although guidelines do not exist, some studies have shown that iNO could be used as a rescue therapy in preterm neonate with severe pulmonary hypertension. Case presentation We describe the case of a preterm neonate, born at 30 + 1 weeks of gestation, with hypoxic respiratory failure not responding to maximal conventional therapy. On the third day of life echocardiography showed severe pulmonary hypertension with right to le…
Relationship between Skin Temperature Variation and Muscle Damage Markers after a Marathon Performed in a Hot Environmental Condition
2021
This study aimed to assess the effect of a marathon running at a hot environmental temperature on the baseline skin temperature (Tsk) of the posterior day and to analyze the relationship between Tsk response and muscle damage markers variation. The Tsk, creatine kinase, and lactate dehydrogenase of 16 marathon runners were assessed four times before (15 days and 45 min) and after (24 h and 6 days) a marathon in a hot environment (thermal stress index = 28.3 ± 3.3 °C and humidity ~81%). The Tsk of thirteen different body regions of both right and left lower limbs were analyzed. Higher values after the marathon were observed than 45 min before in creatine kinase (174.3 ± 136.4 UI/L <
Measurement of exhaled nitric oxide: comparison of 3 different analyzers
2018
Exhaled nitric oxide (FeNO) is used as a surrogate marker to monitor airway inflammation. Aim of this study was to compare the new FeNO analyzer Vivatmo pro from Bosch (BV) with the Niox Vero from Circassia (CN) and the CLD from Ecomedics (EC). In 106 asthma patients (median age 54 years (range 20-87), 60 % female, median ACT of 16, 85 % on inhaled corticosteroids (mean 1300 μg BDP), 36 % on therapy with biologics) 2 FeNO measurements per patient and per device were performed using each analyzer in a random sequence according to the ATS / ERS guidelines. Additionally, the success rate to achieve a valid NO value was evaluated. 70 % of the patients had FeNO values In conclusion, for the rang…
Late Breaking Abstract - Efficacy of CSJ117 on allergen-induced asthmatic responses in mild atopic asthma patients
2020
Introduction: CSJ117 is a potent neutralizing antibody fragment against human Thymic stromal lymphopoietin (TSLP), formulated as a PulmoSol™ engineered powder in hard capsules for delivery to the lungs via dry powder inhaler. Methods: In this double-blind, placebo-controlled study, 28 mild, atopic asthmatics meeting elibility criteria were randomized to receive 4mg CSJ117 (n = 15) or placebo (n = 13) inhaled daily for 12 weeks. Allergen inhalation challenge (AIC) was conducted at screening, day 42 and day 84. The primary efficacy variable was the late asthmatic response (LAR), measured 3 to 7 hours after AIC at day 84. Other outcomes included the early asthmatic response (EAR) measured with…
Late Breaking Abstract - Predictive value of FeNO in patients with non-specific respiratory symptoms: a randomised controlled trial
2017
Background: Fractional exhaled nitric oxide (FeNO) can predict treatment response in asthma, but little is known of its utility in patients with non-specific respiratory symptoms (NSRS). Aims and objectives: To evaluate the association between baseline FeNO and response to treatment with inhaled corticosteroids (ICS) in patients with NSRS. Methods: This was a multi-centre randomised, placebo-controlled trial, carried out in UK and Singapore. It consisted of a 2-week assessment period to establish baseline measurements and a 4-week treatment period with either extrafine ICS (200 µ beclomethasone bid) or placebo. NIOX VERO (Circassia) was used to measure baseline FeNO. The primary endpoint wa…
Asthma-COPD overlap syndrome: recent advances in diagnostic criteria and prognostic significance.
2017
The term asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) has been proposed for individuals with features of both asthma and COPD. Several attempts have been done to define ACOS on the basis of medical history, symptoms, and functional findings. The main diagnostic criteria include airflow obstruction with a strong although incomplete reversibility to bronchodilation tests, a significant exposure to cigarette or biomass smoke, and a history of atopy or asthma. Additional diagnostic elements include eosinophilic airway and systemic inflammation, a good response to corticosteroid treatment, and a high concentration of exhaled nitric oxide. ACOS should be distinguish…
