Lower limb deep vein thrombosis in COVID-19 patients admitted to intermediate care respiratory units.

COVID-19 has been associated with an increased risk of thrombotic events; however, the reported incidence of deep vein thrombosis varies depending, at least in part, on the severity of the disease. Aim of this prospective, multicenter, observational study was to investigate the incidence of lower limb deep vein thrombosis as assessed by compression ultrasound in consecutive patients admitted to three pulmonary medicine wards designated to care for patients with COVID-19 related pneumonia, with or without respiratory failure but not requiring admission to an intensive care unit. Consecutive patients admitted between March 27 and May 6, 2020 were enrolled. Patients were excluded if they were less than 18-year-old or if compression ultrasound could not be performed for any reason. Patients were assessed at admission (t0) and after 7 days (t1). Major and non-major clinically relevant bleedings were recorded. Sixty-eight patients were enrolled. Two were excluded due to anatomical abnormalities that prevented compression ultrasound; sixty patients were retested at (t1). All patients were started on antithrombotic prophylaxis, unless therapeutic anticoagulation was required. Deep vein thrombosis as assessed by compression ultrasound was observed in 2 patients (3%); one of them was later deemed to represent a previous episode. No new episodes were detected at t1. One major and 2 non-major clinically relevant bleedings were observed. In the setting of patients with COVID-related pneumonia not requiring admission to an intensive care unit, the incidence of deep vein thrombosis is low and our data support not screening asymptomatic patients.

Fluticasone furoate, umeclidinium bromide, and vilanterol as a combination therapy for chronic obstructive pulmonary disease.

Introduction: Triple therapy with two bronchodilators (LABA plus LAMA) and an inhaled corticosteroid (ICS) is recommended for patients suffering from severe chronic obstructive pulmonary disease (COPD). Areas covered: All 12-52 week-long studies comparing triple therapy with umeclidinium (UM) added to either fluticasone furoate/vilanterol (FF/VI) or fluticasone propionate/salmeterol (FP/SAL) vs. other comparators in COPD patients of group B or D (2011 GOLD classification) were considered. When UM was added to ICS/LABA with separate devices or within a single device, triple combination was more effective than comparators (usually, ICS/LABA combinations) regarding improvements to pulmonary function, symptoms, quality of life and, in the longer studies, rate of moderate-severe exacerbations. The IMPACT study (a large trial comparing UM/FF/VI with both FF/VI and UM/VI combinations) showed that triple therapy had a greater effect compared to dual therapies in reducing the rate of moderate-severe exacerbations, improving trough FEV1 and improving quality of life. The safety profile was good, without excess cardiovascular effects or pneumonia, however, the presence of comorbidities was frequent. Expert commentary: UM/FF/VI combination represents a good option for severe COPD patients who remain symptomatic and/or with frequent exacerbations despite dual therapies. Once daily administration with a simple and effective device may increase adherence and efficacy of the treatment.
