Recent studies suggest that thrombotic complications are a common phenomenon in the novel SARS-CoV-2 infection. The main objective of our study is to assess cumulative incidence of pulmonary embolism (PE) in non critically ill COVID-19 patients and to identify its predicting factors associated to the diagnosis of pulmonary embolism. We retrospectevely reviewed 452 electronic medical records of patients admitted to Internal Medicine Department of a secondary hospital in Madrid during Covid 19 pandemic outbreak. We included 91 patients who underwent a multidetector Computed Tomography pulmonary angiography(CTPA) during conventional hospitalization. The cumulative incidence of PE was assessed ant the clinical, analytical and radiological characteristics were compared between patients with and without PE. PE incidence was 6.4% (29/452 patients). Most patients with a confirmed diagnosed with PE recieved low molecular weight heparin (LMWH): 79.3% (23/29). D-dimer peak was significatly elevated in PE vs non PE patients (14,480 vs 7230 mcg/dL, p = 0.03). In multivariate analysis of patients who underwent a CTPA we found that plasma D-dimer peak was an independen predictor of PE with a best cut off point of > 5000 µg/dl (OR 3.77; IC95% (1.18-12.16), p = 0.03). We found ninefold increased risk of PE patients not suffering from dyslipidemia (OR 9.06; IC95% (1.88-43.60). Predictive value of AUC for ROC is 75.5%. We found a high incidence of PE in non critically ill hospitalized COVID 19 patients despite standard thromboprophylaxis. An increase in D-dimer levels is an independent predictor for PE, with a best cutoff point of > 5000 µg/ dl.

Background The most susceptible population group to critical and fatal coronavirus disease 2019 (COVID-19) is older adults. In SARS-CoV-2 infection, the host immune response is thought to play a key role in the pathophysiological effects of lung damage. Therefore, corticosteroid therapy could modulate inflammation-mediated pulmonary injury and thereby reduce progression to severe respiratory failure and death. The aim of this study was to analyse the safety and clinical efficacy of corticosteroid therapy in older adults with severe COVID-19 pneumonia. Method We reviewed the clinical records of confirmed COVID-19 patients aged 75 years or older admitted to our hospital over a three months period (March 1, to May 31, 2020). A total of 143 patients were included in the study cohort. From 2 April, 2020, in accordance with World Health Organization (WHO) guidance on COVID-19, our hospital protocol added corticosteroid for COVID-19 treatment. We compared in-hospital mortality among patients with critical COVID-19 who received corticosteroids therapy and those who did not. Results 88 patients (61.5%) were treated with corticosteroids, and 55 patients (38.4%) were not. Both groups were similar in baseline characteristics. The median age was 85 years (IQR, 82–89), and 61.5% (88/143) were male. In-hospital mortality was lower in the corticosteroid group (68.2%) compared with patients in the non-corticosteroid group (81.8%). Treatment with corticosteroids was an independent survival factor (HR=0.61; 95% CI, 0.41–0.93; P=0.006). Conclusions In critically ill older adults with COVID-19 pneumonia, the use of corticosteroid treatment resulted in lower mortality without severe adverse events.

Objectives Several reports had observed a high risk of pulmonary embolism (PE) in patients with coronavirus disease 2019 (COVID‐19), most of them in the intensive care unit. Reported findings indicate that a direct viral‐mediated hyperinflammatory response leads to local thromboinflammation. According to those findings, the incidence of deep venous thrombosis (DVT) in patients with COVID‐19 and PE should be low. The objective of this study was to evaluate the incidence of DVT in patients with COVID‐19 who developed PE. Methods In this prospective observational study, consecutive patients hospitalized in the internal medicine ward with a diagnosis of COVID‐19 who developed PE were screened for DVT in the lower extremities with complete compression ultrasound. Results The study comprised 26 patients. Fifteen patients (57.7%) were male. The median age was 60 years (interquartile range, 54–73 years). Compression ultrasound findings were positive for DVT in 2 patients (7.7%; 95% confidence interval, 3.6%–11.7%). Patients with DVT had central and bilateral PE. In both, venous thromboembolism was diagnosed in the emergency department, so they did not receive previous prophylactic therapy with low‐molecular‐weight heparin. Patients without DVT had higher median d ‐dimer levels: 25,688 μg/dL (interquartile range, 80,000–1210 μg/dL) versus 5310 μg/dL ( P < .05). Conclusions Our study showed a low incidence of DVT in a cohort of patients with COVID‐19 and PE. This observation suggests that PE in these patients could be produced mainly by a local thromboinflammatory syndrome induced by severe acute respiratory syndrome coronavirus 2 infection and not by a thromboembolic event.
