Assessment of the long-term safety of mepolizumab and durability of clinical response in patients with severe eosinophilic asthma
2018
Background Mepolizumab has demonstrated favorable safety and efficacy profiles in placebo-controlled trials of 12 months' duration or less; however, long-term data are lacking. Objective We sought to evaluate the long-term safety and efficacy of mepolizumab in patients with severe eosinophilic asthma (SEA). Methods COLUMBA (Open-label Long Term Extension Safety Study of Mepolizumab in Asthmatic Subjects, NCT01691859 ) was an open-label extension study in patients with SEA previously enrolled in DREAM (Dose Ranging Efficacy And Safety With Mepolizumab in Severe Asthma, NCT01000506 ). Patients received 100 mg of subcutaneous mepolizumab every 4 weeks plus standard of care until a protocol-def…
Measurement of inflammatory mediators of eosinophils and lymphocytes in blood in acute asthma: serum levels of ECP influence the bronchodilator respo…
2002
The aim of this study was to assess the relevance of immunoinflammatory markers on the response to short acting β<sub>2</sub>-agonist in acute asthma exacerbation. Thus, we measured serum eosinophil cationic protein (ECP) levels and sIL-2R at acute exacerbation in 52 adult patients with atopic asthma, and assessed forced expiratory volume in 1 s (FEV<sub>1</sub>) before and after the administration of aerosolized salbutamol. After a cumulative dose of salbutamol causing a 10% improvement in FEV<sub>1</sub> from baseline [CD10, i.e. cumulative doses of salbutamol (800 µg) causing an improvement in FEV<sub>1</sub> from baseline to 10%] the patie…
Prospective, Single-Arm, Longitudinal Study of Biomarkers in Real-World Patients with Severe Asthma.
2019
ARIETTA was a prospective, single-arm, noninterventional, multicenter study in patients with severe asthma.To examine the predictive and prognostic abilities of type 2 biomarkers for severe asthma outcomes.Adult patients with severe asthma receiving daily inhaled corticosteroids (fluticasone propionate ≥500 μg or equivalent) and ≥1 second controller medication were enrolled. Biomarker, clinical, and safety data were collected over 52 weeks. The primary endpoint was the asthma exacerbation rate over 52 weeks in serum periostin-high (≥50 ng/mL at baseline) versus periostin-low subgroups (50 ng/mL). Correlations between biomarker levels (periostin, blood eosinophils, IgE, and fractional exhale…
[Correlation, in previously treated HIV-1 positive patients, between hypersensitivity reaction to abacavir and the presence of the HLA-B*5701 allele].
2009
Abstract Introduction Hypersensitivity reaction to abacavir (a powerful inverse transcriptase inhibitor) is a serious adverse effect that limits its use in antiretroviral treatment and requires a high level of clinical surveillance. Certain haplotypes of the primary histocompatibility complex proteins (HLA-B*5701) are very significant predictors of the risk of hypersensitivity to this drug. The purpose of this study is to identify the cases where a probable hypersensitivity reaction to abacavir presented the HLA-B*5701 allele. Method A retrospective study was conducted in all HIV-1 positive adult patients infected treated with abacavir between January 2000 and December 2007, in Department 6…
Current practice of chronic hepatitis B treatment in Southern Italy
2012
Abstract Background Treatment choice for chronic HBV infection is a continuously evolving issue, with a wide range of options. We aimed to evaluate the current practice of HBV therapies in the real world in Southern Italy. Methods A prospective study enrolling over a six month period (February–July 2010) all consecutive HBsAg positive subjects, never previously treated, referred to 16 liver units in two Southern Italy regions (Calabria and Sicily). Results Out of 247 subjects evaluated, 116 (46.9%) had HBV-DNA undetectable or lower than 2000 UI/ml. There were 108 (43.7%) inactive carriers, 103 (41.7%) chronic hepatitis, and 36 (14.6%) liver cirrhosis. Antiviral treatment was planned in 94 (…
Clinical performance of a new medullary humeral nail: antegrade versus retrograde insertion.
2001
Objective A new intramedullary nail system for humeral shaft fractures is evaluated to determine whether retrograde nailing is as reliable as antegrade nailing. Study design Prospective multicenter nonrandomized clinical study. Patients Eighty-four patients with acute humeral shaft fractures were nailed with the new unreamed humeral nail (UHN) system. Fifty-seven nails were introduced retrogradely, and twenty-seven antegradely. Bone healing and functional outcome were the follow-up parameters. Results The ratio of perioperative complications was equivalent for both groups, but one shaft fracture and three fractures or fissures at the entry point occurred in the group with retrograde nail in…
Corneal Biomechanical Parameters With Corneoscleral Contact Lenses in Post-Laser In Situ Keratomileusis Eyes
2018
Objective: To evaluate corneal biomechanical parameters wearing corneoscleral contact lenses (CScL) in patients with irregular corneas after laser in situ keratomileusis (LASIK). Methods: Data from patients fitted with CScL because of corneal surface irregularities after complicated LASIK surgery were selected by two eye clinics. Previously and after 1 year of CScL fitting, corneal hysteresis (CH), corneal resistance factor (CRF), corneal-compensated intraocular pressure (IOPcc), and central corneal thickness were evaluated. In addition, visual acuity, subjective comfort, and wearing time CScL were reported. Results: The study comprised 27 eyes. Statistically significant differences were fo…
Albumin clearance from human skeletal muscle during prolonged steady-state running.
2001
This study was designed to find out if the lymph flow, indicated as albumin clearance, from active skeletal muscle is maintained constant during a prolonged steady-state exercise. 99mTc-labelled albumin was injected bilaterally into the vastus lateralis muscles of eight endurance-trained men. The radioactivity at the injection site was monitored by a gamma-camera before, frequently during, and after a 2 h run at a controlled steady intensity of 69 +/- 4% of the maximal heart rate. The fractional clearance rate of albumin was calculated for each monitoring interval, and was expressed as percentage clearance per minute (% min(-1)). During the first 15 min of exercise the clearance rate was fi…
Dynamic cerebrovascular autoregulation in patients prone to postural syncope: Comparison of techniques assessing the autoregulation index from sponta…
2021
Abstract Three approaches to the assessment of cerebrovascular autoregulation (CA) via the computation of the autoregulation index (ARI) from spontaneous variability of mean arterial pressure (MAP) and mean cerebral blood flow velocity (MCBFV) were applied: 1) a time domain method (TDM); 2) a nonparametric method (nonPM); 3) a parametric method (PM). Performances were tested over matched and surrogate unmatched pairs. Data were analyzed at supine resting (REST) and during the early phase of 60° head-up tilt (TILT) in 13 subjects with previous history of postural syncope (SYNC, age: 28 ± 9 yrs.; 5 males) and 13 control individuals (noSYNC, age: 27 ± 8 yrs.; 5 males). Analysis was completed b…
Use of nucleoside reverse transcriptase inhibitors and risk of myocardial infarction in HIV-infected patients enrolled in the D:A:D study: a multi-co…
2008
Background: Whether nucleoside reverse transcriptase inhibitors increase the risk of myocardial infarction in HIV-infected individuals is unclear. Our aim was to explore whether exposure to such drugs was associated with an excess risk of myocardial infarction in a large, prospective observational cohort of HIV-infected patients. Methods: We used Poisson regression models to quantify the relation between cumulative, recent (currently or within the preceding 6 months), and past use of zidovudine, didanosine, stavudine, lamivudine, and abacavir and development of myocardial infarction in 33 347 patients enrolled in the D:A:D study. We adjusted for cardiovascular risk factors that are unlikely…
