Risk factors for exacerbations and pneumonia in patients with chronic obstructive pulmonary disease: a pooled analysis.
BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) are at risk of exacerbations and pneumonia; how the risk factors interact is unclear. METHODS: This post-hoc, pooled analysis included studies of COPD patients treated with inhaled corticosteroid (ICS)/long-acting ÎČ2 agonist (LABA) combinations and comparator arms of ICS, LABA, and/or placebo. Backward elimination via Cox's proportional hazards regression modelling evaluated which combination of risk factors best predicts time to first (a) pneumonia, and (b) moderate/severe COPD exacerbation. RESULTS: Five studies contributed: NCT01009463, NCT01017952, NCT00144911, NCT00115492, and NCT00268216. Low body mass index (BMI), exacerbation history, worsening lung function (Global Initiative for Chronic Obstructive Lung Disease [GOLD] stage), and ICS treatment were identified as factors increasing pneumonia risk. BMI was the only pneumonia risk factor influenced by ICS treatment, with ICS further increasing risk for those with BMI <25âkg/m2. The modelled probability of pneumonia varied between 3 and 12% during the first year. Higher exacerbation risk was associated with a history of exacerbations, poorer lung function (GOLD stage), female sex and absence of ICS treatment. The influence of the other exacerbation risk factors was not modified by ICS treatment. Modelled probabilities of an exacerbation varied between 31 and 82% during the first year. CONCLUSIONS: The probability of an exacerbation was considerably higher than for pneumonia. ICS reduced exacerbations but did not influence the effect of risks associated with prior exacerbation history, GOLD stage, or female sex. The only identified risk factor for ICS-induced pneumonia was BMI <25âkg/m2. Analyses of this type may help the development of COPD risk equations
Efficacy and safety of once-daily fluticasone furoate/vilanterol (100/25 mcg) versus twice-daily fluticasone propionate/salmeterol (250/50 mcg) in COPD patients
SummaryBackgroundFluticasone furoate/vilanterol (FF/VI) is an inhaled corticosteroid/long-acting beta2-agonist (ICS/LABA), recently approved as once-daily maintenance therapy for COPD. We compared the lung function effects of FF/VI with those of twice-daily fluticasone propionate/salmeterol (FP/SAL).MethodsThree 12 week studies comparing FF/VI and FP/SAL were conducted. Patients aged â„40 years with moderate-to-very severe COPD were randomized to receive double-blind, double-dummy FF/VI 100/25Â mcg once-daily, or FP/SAL 250/50Â mcg twice-daily for 12 weeks following a 2 week placebo run-in period. The primary endpoint of each study was change from baseline trough in 0â24Â h weighted mean FEV1 (wmFEV1) on Day 84. Safety was also assessed.ResultsIn Study 1 (HZC113109) (intent-to-treat n: FF/VIÂ =Â 260; FP/SALÂ =Â 259), the increase from baseline in 0â24Â h wmFEV1 was significantly greater with FF/VI than FP/SAL (Î80Â mL, PÂ <Â 0.001). In Study 2 (HZC112352) (intent-to-treat n: FF/VIÂ =Â 259; FP/SALÂ =Â 252) and Study 3 (RLV116974) (intent-to-treat n: FF/VIÂ =Â 412; FP/SALÂ =Â 416), the increase from baseline in 0â24Â h wmFEV1 was not significantly greater with FF/VI than FP/SAL (Î29Â mL, PÂ =Â 0.267; Î25Â mL, PÂ =Â 0.137). The treatment difference was statistically but not clinically significant in a pooled analysis (Î41Â mL, PÂ <Â 0.001). Pooled adverse events (FF/VI 27%; FP/SAL 28%) and serious adverse events (FF/VI 2%; FP/SAL 3%) were similar between treatments.ConclusionsOur data suggest that once-daily FF/VI 100/25Â mcg provides FEV1 improvement in COPD that is at least comparable with that conferred by twice-daily FP/SAL 250/50Â mcg, although interpretation is limited by differences in individual study outcomes. The safety profiles of FF/VI 100/25Â mcg and FP/SAL 250/50Â mcg are similar.Clinical trial registrationclinicaltrials.gov: NCT01323634; NCT01323621; NCT01706328.

Efficacy and safety of 4 weeks' treatment with combined fluticasone furoate/vilanterol in a single inhaler given once daily in COPD: a placebo-controlled randomised trial
Background: Fluticasone furoate/vilanterol (FF/VI) is a novel once-daily (OD) inhaled corticosteroid/long-acting beta(2) agonist combination in development for chronic obstructive pulmonary disease (COPD) and asthma. Trial design: A multicentre, randomised, double-blind, parallel-group, placebo-controlled study. Methods: Participants were patients with moderate-to-severe COPD treated with placebo or FF/VI 400/25 mu g OD for 4 weeks. Study objectives were to assess the safety and efficacy of FF/VI 400/25 mg OD administered for 4 weeks via a novel dry powder inhaler. Co-primary end points were change from baseline in weighted mean (wm) heart rate 0-4 h postdose at day 28 and the incidence of adverse events (AEs). Secondary end points included change from baseline in trough forced expiratory volume in one second (FEV1) (23-24 h postdose; day 29) and wm FEV1 (0-4 h postdose; day 28). Patients were randomised to receive FF/VI 400/25 mg or placebo in a 2: 1 ratio; all patients and investigators were blinded to active or placebo treatment. Results: 60 patients (mean age 64 years) were randomised (FF/VI: n=40; placebo: n=20), and all contributed data to the analysis. Mean screening post-bronchodilator FEV1 per cent predicted was comparable between groups (FF/VI: 58.5%; placebo: 60.1%). The wm heart rate 0-4 h postdose was similar between groups (difference: 0.6 beats per minute; 95% CI -3.9 to 5.1). More on-treatment AEs were reported in the FF/VI group (68%) compared with the placebo group (50%). The most common drug-related AEs in the FF/VI group were oral candidiasis (8%) and dysphonia (5%). There were no clinically relevant effects on laboratory values, including glucose and potassium, or on vital signs or ECGs/Holters. The FF/VI group had statistically greater improvements compared with placebo in trough FEV1 (mean difference 183 ml) and 0-4 h postdose wm FEV1 (mean difference 236 ml). Conclusion: FF/VI has a good safety and tolerability profile and improves lung function compared with placebo in patients with COPD. Trial registration number: clinical trials. gov-NCT00731822
Computed tomography and magnetic resonance imaging of desmoplastic fibroma with simultaneous manifestation in two unusual locations: a case report
<p>Abstract</p> <p>Introduction</p> <p>Desmoplastic fibroma is an extremely rare primary benign bone tumor. It occurs most often in the mandible, followed by the femur and pelvis. To the best of our knowledge, fewer than 200 cases have been described in the published literature. Furthermore, this case is the first report of desmoplastic fibroma with simultaneous presentation in two different locations.</p> <p>Case presentation</p> <p>We present an unusual case of desmoplastic fibroma in a 56-year-old Caucasian man, who presented to our hospital with lumbar pain. Computed tomography and magnetic resonance imaging were performed, demonstrating two lytic expansile lesions affecting both his left iliac bone and his left sacral wing. Curettage and cortical-cancellous grafting was performed, followed by postoperative computed tomography and magnetic resonance imaging.</p> <p>Conclusion</p> <p>Desmoplastic fibroma with unusual and simultaneous manifestations in two different locations has never been reported previously to the best of our knowledge. The purpose of this case report is to present the computed tomography and magnetic resonance imaging features of this rare tumor before and after the surgical treatment. Furthermore, the radiological findings with the description of the characteristics and the clinical presentation of this rare tumor, contribute to the wide spectrum of manifestations of this tumor, in order to recognize it and to have the appropriate management.</p
IDENTIFICAZIONE DELLE LESIONI POLMONARI IN RM CON UNA SEQUENZA VIBE MODIFICATA E CON UNA SEQUENZA VIBE STANDARD: UN CONFRONTO CON LA TC.
Scopo
valutare l\u2019accuratezza della RM a 3 Tesla nell\u2019individuazione di lesioni polmonari con una
sequenza VIBE modificata e con una sequenza VIBE standard, usando la TC come riferimento.
Materiale e metodi
abbiamo rivalutato retrospettivamente 37 pazienti oncologici (11 pediatrici e 26 adulti; 19 F)
sottoposti a TC e PET/RM da 3T il cui protocollo prevedeva una sequenza VIBE acquisita a
respiro trattenuto con echo time (TE) di 0.89 ms e flip angle (FA) di 3\ub0. Le VIBE sono state
valutate da tre osservatori per l'identificazione di noduli >5mm o =5mm. Un quarto
osservatore ha valutato delle sequenze VIBE standard (TE di 1.2 ms e FA di 10\ub0), anch\u2019esse
incluse nel protocollo, ed infine un quinto lettore ha analizzato le immagini TC (considerate
come standard di riferimento).Sia per paziente che per singola lesione sono state calcolate
sensibilit\ue0 e specificit\ue0 per le due categorie di noduli ed il coefficiente di correlazione intraclasse
(ICC) per i lettori delle VIBE modificate.
Risultati
analisi per paziente (positivit\ue0=1 lesione): sensibilit\ue0 84.6% e specificit\ue0 di 100% per
noduli>5mm (VIBE standard 69.2% e 100%) e 44.4% e 100% per noduli=5mm (VIBE standard
33.3% e 100%). Analisi per lesione (presenza/assenza): sensibilit\ue0 di 83.9% per noduli>5mm
(VIBE standard 67.74%) e 37.5% per noduli=5mm (VIBE standard 18.7%). L\u2019ICC nell\u2019analisi
per paziente era 0.911 per noduli>5mm e 0.902 per noduli=5mm; nell\u2019analisi per lesione
0.866 per noduli>5mm e 0.699 per noduli=5mm.
Conclusioni
la sequenza VIBE modificata \ue8 riproducibile ed accurata per l\u2019individuazione di noduli >5mm,
mentre l\u2019accuratezza risulta meno soddisfacente per i noduli=5mm. L\u2019utilizzo della sequenza
modificata nei protocolli RM sembra ragionevole per migliorare la visualizzazione del polmone
Reduction in All-Cause Mortality with Fluticasone Furoate/Umeclidinium/Vilanterol in COPD Patients
Rationale: The IMPACT trial demonstrated a significant reduction in all-cause mortality (ACM) risk with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus FF/VI or UMEC/VI in patients with COPD at risk of future exacerbations. 574 patients were censored from the original analysis due to incomplete vital status information. Objective: Report ACM and impact of stepping down therapy, following collection of additional vital status data. Methods: Patients were randomized 2:2:1 to FF/UMEC/VI 100/62.5/25”g, FF/VI 100/25”g or UMEC/VI 62.5/25”g following a run-in on their COPD therapies. Time to ACM was prespecified. Additional vital status data collection and subsequent analyses were performed post hoc. Measurements and Main Results: We report vital status data for 99.6% of the intention-to-treat population (n=10,355), documenting 98(2.36%) deaths on FF/UMEC/VI, 109(2.64%) on FF/VI, and 66(3.19%) on UMEC/VI. For FF/UMEC/VI, the hazard ratio for death was 0.72 (95%CI: 0.53,0.99;P=0.042) versus UMEC/VI and 0.89 (95%CI: 0.67,1.16;P=0.387) versus FF/VI. Independent adjudication confirmed lower rates of cardiovascular and respiratory death, and death associated with the patientâs COPD. Conclusions: In this secondary analysis of an efficacy outcome from the IMPACT trial, once-daily single-inhaler FF/UMEC/VI triple therapy reduced the risk of ACM versus UMEC/VI in patients with symptomatic COPD and a history of exacerbations.
