No full textCommunity acquired pneumonia: a cost-of-illness analysis in Greece
No full textIntroduction: Community acquired pneumonia (CAP) is an acute respiratory infection with high clinical and economic burden, especially when hospitalisation is required. The present study aimed to assess the mean direct cost per CAP outpatient and inpatient care in Greece, in the absence of previous estimates. Methods: A retrospective analysis of patients at a tertiary hospital, treated between October 2015 and March 2016, was conducted. Resource use data for inpatients and outpatients were collected (diagnostic tests, medication, physician visits and length of hospitalisation, where applicable). Cost calculations followed a third party payer perspective. Additionally, two regression models were employed to identify the determinants of hospitalisation and the main drivers of inpatient and outpatient cost. Results: Overall, 149 inpatients and 100 outpatients were included in the analysis. Mean hospitalisation duration was 11.35 days (standard deviation (SD)=9.71 days). Mean direct cost per patient was (sic)110.64 (SD=(sic)58.23) and (sic)7406.56 (SD=(sic)12,124.93) for outpatient and inpatient cases respectively. (At the time period for the study, (sic)1.00 was approximately A$1.50.) The main inpatient cost driver was hospitalisation (94.97%), followed by medication (3.30%) and diagnostic tests (0.87%). For outpatients, key cost drivers, in order of magnitude, were prescribed medication (38.84%), diagnostic tests (33.51%) and physician visits (17.54%). The regression analyses showed that the probability of hospitalisation increases with age and number of symptoms, whereas average cost is mainly influenced by gender, duration and number of symptoms, and the presence of comorbidities. Conclusion: The results indicate that, in Greece, CAP is accompanied by a significant economic burden, mainly attributable to hospitalisation. Interventions toward reducing the influence of contributors to the incidence and probability of hospitalisation are essential from a clinical and policy perspective. Also, the association of symptoms - in terms of number and duration - and age with hospitalisation probability and costs highlights that special attention should be given to the high risk groups of the population, such as the elderly and the rural residents, both in terms of preventive and therapeutic services
Effects of smoking cessation on serum leptin and adiponectin levels
No full textBackground: Evidence on the association of leptin and adiponectin and smoking is limited and discordant. Leptin and adiponectin represent the most abundant adipokines in human plasma that play crucial roles in the pathophysiology of metabolic syndrome, atherosclerosis and insulin resistance. Leptin up-regulates the expression of several pro-inflammatory cytokines and is increased upon weight gain. Adiponectin has been shown to possess insulin sensitizing, anti -inflammatory and anti-atherogenic properties and is increased upon weight reduction. Our aim was to assess the effects of smoking cessation on serum leptin and adiponectin levels. Methods: We assessed the changes in serum leptin and adiponectin levels, serum CRP levels and BMI in apparently healthy smokers after 3 and 6 months of abstinence from smoking. Successful cessation was confirmed by an exhaled carbon monoxide measurement. 26 healthy non-smokers were recruited as controls. Results: Among the sample group, 32 subjects had quitted smoking at 3 months and 29 subjects at 6 months. Samples' leptin increased significantly from baseline to three months (mean change 3.76 ng/ml [95 % CI 0.89, 6.64], p = 0.012) and then decreased significantly from three to six months of smoking cessation (mean change -4,29 ng/ml [95 % CI -7.34, -6.64], p = 0.008). Samples' adiponectin increased significantly from baseline to three months of abstinence from smoking (mean change 2.34 [95 % CI -0.05, 4.73], p -0.05). BMI was significantly increased (mean change 2.03 kg/m(2) [95 % CI 1.60, 2.46], p < 0.05), while CRP decreased significantly from baseline to 6 months of smoking cessation (mean change -0.68 mg/dl [95 % CI -1.06, -0.30], p = 0.001). Conclusions: Smoking quitters' leptin levels appear to increase 3 months after smoking cessation and then decrease from 3 to 6 months of abstinence from smoking. Adiponectin levels increase during the first trimester of smoking cessation. The decrease in CRP levels indicates that the low grade inflammation observed in smokers is gradually restored. The alterations of serum leptin and adiponectin after 6 months of smoking cessation suggest the same but do not reach statistically significant levels. Weight gain and changes in fat distribution may attenuate the beneficial effects of smoking cessation

Efficacy and safety of direct switch to indacaterol/glycopyrronium in patients with moderate COPD: The CRYSTAL open-label randomised trial
No full textBackground: Dual bronchodilation combining a long-acting β2-agonist (LABA) and a long-acting muscarinic antagonist (LAMA) is the preferred choice of treatment recommended by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 guidelines for the management of patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). The once-daily (q.d.) fixed-dose combination (FDC) of LABA, indacaterol 110 μg and LAMA, glycopyrronium 50 μg (IND/GLY 110/50 μg q.d.) demonstrated superior improvements in lung function, dyspnoea and overall health status and better tolerability against LABA or LAMA monotherapies and combination of LABA and inhaled corticosteroid (ICS) in more than 11,000 patients with moderate-to-severe COPD in several randomised controlled clinical trials. Methods: The CRYSTAL study was the first, 12-week, randomised, open-label trial that evaluated the efficacy and safety of a direct switch from previous treatments to IND/GLY 110/50 μg q.d. on lung function and dyspnoea in patients with moderate COPD and a history of up to one exacerbation in the previous year. Patients were divided into 2 groups according to their background therapy and symptom scores and were randomised (3:1) to IND/GLY or to continue with their previous treatments. Results: The study included 4389 randomised patients, of whom 2160 were in groups switched to IND/GLY (intention-to-treat population). The effect of IND/GLY was superior to LABA + ICS on trough forced expiratory volume in 1 s (FEV1; treatment difference, Δ = +71 mL) and transition dyspnoea index (TDI; [Δ = 1.09 units]), and to LABA or LAMA on trough FEV1 (Δ = +101 mL) and a TDI (Δ = 1.26 units). Improvements in health status and lower rescue medication use were also observed with IND/GLY. The safety profile of the study medication was similar to that observed in previous studies. Conclusions: IND/GLY demonstrated superior improvements in lung function and dyspnoea after direct switch from previous treatments.
