Coronavirus disease (COVID-19) may predispose patients to pulmonary embolism (PE), despite standard thromboprophylaxis. Our retrospective study aimed to report the prevalence of PE in patients with COVID-19 and severe respiratory failure (SRF) treated with intermediate- to full-dose enoxaparin. We analyzed data from patients with COVID-19 pneumonia and SRF admitted to our Respiratory Intensive Care Unit (RICU) from February 27 to April 20, 2020. All patients received at least intermediate-dose enoxaparin (40 mg twice daily). Computed tomography pulmonary angiography (CTPA) was used to detect PE. Ninety-two patients with COVID-19 pneumonia and SRF were admitted to our RICU. Twenty-two patients underwent CTPA (24 %), 11 of whom had PEs (12%). We hypothesize that the enoxaparin treatment may be responsible for the lower prevalence of PE as compared to previous reports of similar patients, even if our report had several limitations, mainly the small sample size.

Abstract Background: Coronavirus disease 2019 (COVID-19) may predispose patients to venous thromboembolism (VTE) due to inflammation, hypoxia, immobilization, and diffuse intravascular coagulation, despite standard thrombopropylaxis. Our retrospective study reports the incidence of pulmonary embolism (PE) in patients with COVID-19 and severe respiratory failure(SRF) treated with intermediate to full-dose enoxaparin. .Methods: This retrospective case series analysed data from patients with COVID-19 pneumonia and severe respiratory failure (SRF) admitted to our Respiratory Intensive Care Unit (RICU) between February 27 and April 20, 2020 for non-invasive positive-pressure ventilation. All patients received at least intermediate-dose enoxaparin (40 mg twice daily). If PE was suspected or diagnosed, patients were treated with full-dose enoxaparin (1 mg/kg twice daily). Computed tomography pulmonary angiography (CTPA) was used to detect PE in patients with elevated D-dimer levels (> 3000 ng/mL) and/or other clinical indicators, including sudden worsening of cardiopulmonary status.Results: Ninety-two patients (71 males, 21 females; mean age 58 ± 11 years) with COVID-19 pneumonia and SRF (mean arterial oxygen partial pressure/fractional inspired oxygen [PaO2/FiO2] of 143 ± 45 mm Hg) were admitted to our RICU. Twenty-two patients underwent CTPA (24%), with PEs detected in 11 (12%). Mean PaO2/FiO2 and mean D-dimer levels did not significantly differ between patients with or without PE. Eleven patients (12%) died in the hospital, with a mean age of 70 ± 11 years for deceased patients and 56 ± 11 years for surviving patients (p < 0.0001).Conclusions: PE was diagnosed in 12% of patients despite intermediate to full-dose enoxaparin treatment. However the incidence of PE in our patients was lower than that previously reported. We hypothesize that this reduced PE incidence may have been secondary to the higher than prophylactic enoxaparin dose that was used.

Introduction: Early diagnosis of pulmonary embolism can reduce morbidity and motility. D-dimer is well known parameter having high negative prediction value. This study focused on role of D-dimer in early prediction of presence and severity of pulmonary embolism. Material and Methods: Thirty patients with clinical suspicion of pulmonary embolism along with high D-dimer value were included in this study. All selected patients underwent computed tomography pulmonary angiography assessment. D-dimer value was correlated with presence and proximity of pulmonary embolism. Results: Out of thirty selected patients 50% had pulmonary embolism on computed tomography pulmonary angiography assessment. D-dimer value correlated well with presence and proximity of pulmonary embolism. Conclusion: D-dimer value more than 4000 ng/ml had high positive prediction value (79%) in suspected clinical cases. Value more than 8000 ng/ml further improve value to nearly 100% in suspected cases.

Objectives: Early in the coronavirus 2019 (COVID-19) pandemic, a high frequency of pulmonary embolism was identified. This audit aims to assess the frequency and severity of pulmonary embolism in 2020 compared to 2019. Methods: In this retrospective audit, we compared computed tomography pulmonary angiography (CTPA) frequency and pulmonary embolism severity in April and May 2020, compared to 2019. Pulmonary embolism severity was assessed with the Modified Miller score and the presence of right heart strain was assessed. Demographic information and 30-day mortality was identified from electronic health records. Results: In April 2020, there was a 17% reduction in the number of CTPA performed and an increase in the proportion identifying pulmonary embolism (26%, n = 68/265 vs 15%, n = 47/320, p < 0.001), compared to April 2019. Patients with pulmonary embolism in 2020 had more comorbidities (p = 0.026), but similar age and sex compared to 2019. There was no difference in pulmonary embolism severity in 2020 compared to 2019, but there was an increased frequency of right heart strain in May 2020 (29 vs 12%, p = 0.029). Amongst 18 patients with COVID-19 and pulmonary embolism, there was a larger proportion of males and an increased 30 day mortality (28% vs 6%, p = 0.008). Conclusion: During the COVID-19 pandemic, there was a reduction in the number of CTPA scans performed and an increase in the frequency of CTPA scans positive for pulmonary embolism. Patients with both COVID-19 and pulmonary embolism had an increased risk of 30-day mortality compared to those without COVID-19. Advances in knowledge: During the COVID-19 pandemic, the number of CTPA performed decreased and the proportion of positive CTPA increased. Patients with both pulmonary embolism and COVID-19 had worse outcomes compared to those with pulmonary embolism alone.

Abstract Resveratrol is a polyphenol that has been well studied and has demonstrated anti-viral and anti-inflammatory properties that might mitigate the effects of COVID-19. Outpatients (N=105) were recruited from central Ohio in late 2020. Participants were randomly assigned to receive placebo or resveratrol. Both groups received a single dose of Vitamin D3 which was used as an adjunct. The primary outcome measure was hospitalization within 21 days of symptom onset; secondary measures were ER visits, incidence of pneumonia and pulmonary embolism. Five patients chose not to participate after randomization. Twenty-one day outcome was determined of all one hundred participants (mean [SD] age 55.6 [8.8] years; 61% female) (or their surrogates). There were no clinically significant adverse events attributed to resveratrol. Outpatients in this phase 2 study treated with resveratrol had a lower incidence compared to placebo of: hospitalization (2% vs. 6%, RR 0.33, 95% CI 0.04-3.10), COVID-related ER visits (8% vs. 14%, RR 0.57, 95% CI 0.18-1.83), and pneumonia (8% vs. 16%, RR 0.5, 95% CI 0.16-1.55). One patient (2%) in each group developed pulmonary embolism (RR 1.00, 95% CI: 0.06-15.55). This underpowered study was limited by small sample size and low incidence of primary adverse events. A larger trial could determine efficacy.TRIAL REGISTRATIONS: ClinicalTrials.gov NCT04400890 26/05/2020; FDA IND #150033 05/05/2020

SummaryDuring the last three decades, considerable advances in the management of patients with suspected pulmonary embolism (PE) have improved diagnostic accuracy and made management algorithms safer, easier to use and well standardized. These diagnostic algorithms are mainly based on the assessment of clinical pretest probability, D-Dimer measurement and imaging tests, mainly computed tomography pulmonary angiography (CTPA). These diagnostic algorithms allow a safe and cost-effective diagnosis for most patients with suspected PE.In this review, we discuss current existing evidence for PE diagnosis, the challenge of diagnosing PE in special patient populations, as well as novel imaging tests for PE diagnosis.
