Background: COPD patients have an increased risk of cardiovascular disease and venous thromboembolism.Methods: This study aimed to investigate whether patients with stable COPD have a prothrombotic state compared to COPD-free smokers. We conducted an observational study comparing levels of: D-dimers, INR, aPTT, coagulation factors; fibrinogen, FII, FV, FVII, FVIII, FIX, FX and coagulation inhibitors; protein S, proteins C and antithrombin between stable COPD patients and control subjects.Results: A total of 103 COPD patients and 42 controls with similar age, sex, current smoking status, comorbidity burden and cardiovascular risk met the inclusion criteria. Compared to controls, COPD patients had higher levels of D-dimers (median (interquartile range): 360 (230–600) ng·mL⁻¹versus240 (180–400) ng·mL⁻¹, p=0.001), fibrinogen (mean±sd: 399±82 mg·dL⁻¹versus346±65 mg·dL⁻¹, p<0.001), FII (122±22%versus109±19%, p=0.004), FV (131±25%versus121±19%, p=0.015), FVIII (143±32%versus122±20%, p<0.001) and FX (111 (94–134)%versus98 (88–107)%, p=0.002), and lower levels of protein S (95 (85–105)%versus116 (98–121)%, p<0.001) and antithrombin (94.4±11.5%versus102.3±13.2%, p=0.001). In the COPD group, patients with more severe airflow limitation and frequent exacerbations had significantly higher levels of FII, FV and FX, whereas patients with higher COPD assessment test score had significantly higher levels of FX and lower levels of protein S.Conclusion: Patients with stable COPD exhibited increased levels of key coagulation factors and decreased levels of coagulation inhibitors, namely protein S and antithrombin, compared to COPD-free smokers. Among COPD patients, increased levels of FII, FV and FX and decreased levels of protein S were found in patients with more severe disease.

Chronic Obstructive Pulmonary Disease (COPD) is a chronic inflammatory disease with multisystemic manifestations. Studies either held on stable disease patients or during exacerbations have demonstrated that COPD is strongly related to venous thromboembolism and cardiovascular events. The aim of the present review of the literature was to provide an in-depth overview regarding the alterations of coagulation factors and prothrombotic changes generated in patients with stable COPD and during COPD exacerbations.

BACKGROUND:Ocular tuberculosis (TB) is a clinical entity that presents with a wide range of clinical manifestations. It is regarded as an extremely challenging condition from the point of view of diagnostic approach and calls for early diagnosis and ...

Echocardiographic markers of right ventricular dysfunction or pressure overload (RV_d/PO) have been used in risk assessment of patients with acute pulmonary embolism (APE). Nevertheless, the role of echocardiography in these patients is incompletely determined. We evaluated the right ventricular function using 'non-conventional' markers of RV_d/PO in patients with APE. This was a prospective, single-arm, single-centre study. Consecutive adult patients hospitalised for APE were included. The RV free wall longitudinal strain (RV-FWLS), the fractional area change (FAC), the ratio tricuspid annular plane systolic excursion (TAPSE)/pulmonary arterial systolic pressure (PASP), and the pulmonary vascular resistance (PVR) were evaluated. One hundred patients (mean age 70.0 ± 13.9 years, female 48%) were screened and 73 had adequate RV-FWLS images. The most common abnormal echocardiographic marker was RV-FWLS (44/73; p < 0.001, for all other echocardiographic indices). Thirty-one patients had either PASP ≥ 36 mmHg or PVR > 2 WU (49.2% of the patients with both indices available). There were significant correlations between RV-FWLS, TAPSE/PASP and PVR with both D-Dimers and B-type natriuretic peptide (BNP), and between FAC and BNP. RF-FWLS differed significantly between patients with a simplified pulmonary embolism severity index (sPESI) score 0 and those with a score ≥1 (p < 0.001). RV_d/PO coexists with APE in a large proportion of patients. RV-FWLS is the most abnormal echocardiographic sign and is related to clinical and biochemical prognostic indices.

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease of the airways and lung parenchyma with multiple systemic manifestations. Exacerbations of COPD are important events during the course of the disease, as they are associated with increased mortality, severe impairment of health-related quality of life, accelerated decline in lung function, significant reduction in physical activity, and substantial economic burden. Telemedicine is the use of communication technologies to transmit medical data over short or long distances and to deliver healthcare services. The need to limit in-person appointments during the COVID-19 pandemic has caused a rapid increase in telemedicine services. In the present review of the literature covering published randomized controlled trials reporting results regarding the use of digital tools in acute exacerbations of COPD, we attempt to clarify the effectiveness of telemedicine for identifying, preventing, and reducing COPD exacerbations and improving other clinically relevant outcomes, while describing in detail the specific telemedicine interventions used.

Purpose: This multicenter, prospective, observational study aimed to supplement real-world evidence on the effects of aclidinium bromide on the quality of life (QoL), symptoms, and activity impairment of patients with COPD. Patients and Methods: Eligible patients were ≥ 40 years of age, newly initiated on aclidinium bromide as monotherapy or add-on therapy according to the product’s approved label. Patient-reported COPD assessment test (CAT), the severity of symptoms and their impact on daily activities, and the features of the Genuair^® inhaler device were assessed at enrollment and at 12 weeks post-treatment onset. Results: Between 13 March 2015 and 29 January 2016, 285 eligible consenting patients (76.3% males; median age: 69.0 years; 26.0% newly diagnosed with COPD) were enrolled by 15 hospital-based respiratory medicine specialists in Greece. Aclidinium bromide was initiated as add-on therapy to other inhaled maintenance medications in 73.1% of evaluable patients. The median (interquartile range [IQR]) baseline CAT score decreased from 14.0 (9.0– 20.0) to 10.0 (6.0– 15.0) points (p< 0.001) after 12 weeks of treatment, with 76.5% of the patients achieving a ≥ 2-point decrease. The severity of night-time and early-morning symptoms, assessed using a 5-point Likert-type scale, decreased from a median (IQR) of 1.0 (0.0– 2.0) to 0.0 (0.0– 1.0), and from 2.0 (1.0– 2.0) to 1.0 (1.0– 2.0), respectively (p< 0.001 for both). In patients with paired data, the prevalence of at least moderate night-time symptoms, early-morning symptoms, and daily activity impairment decreased from 28.2% to 19.1%, from 63.6% to 34.2%, and from 59.5% to 38.7%, respectively (p< 0.001 for all). Inhaler device features were assessed as “very good”/“good” by more than 90% of the patients. The adverse drug reaction rate was 1.4%. Conclusion: The study provides real-world evidence on the beneficial effects of aclidinium bromide on the patients’ QoL, symptom severity, and daily activity impairment, which are complemented by a favorable safety profile and high patient satisfaction with the inhaler device.
