RESUMEN
INTRODUCTION: Cancer-related pulmonary embolism (PE) is associated with poor prognosis. Some decision rules identifying patients eligible for home treatment categorize cancer patients at high risk of complications, precluding home treatment. We sought to assess the effectiveness and the safety of outpatient management of patients with low-risk cancer-associated PE. METHODS: In the HOME-PE trial, hemodynamically stable patients with symptomatic PE were randomized to either triaging with Hestia criteria or sPESI score. We analyzed 3 groups of low-risk PE patients: 47 with active cancer treated at home (group 1), 691 without active cancer treated at home (group 2), and 33 with active cancer as the only sPESI criterion qualifying them for hospitalization (group 3). The main outcome was the composite of recurrent venous thromboembolism, major bleeding, and all-cause death within 30 days after randomization. RESULTS: Patients treated at home had composite outcome rates of 4.3 % (2/47) for those with cancer vs. 1.0 % (7/691) for those without (odds ratio (OR) 4.98, 95%CI 1.15-21.49). Patients with cancer had rates of complications of 4.3 % when treated at home vs. 3.0 % (1/33) when hospitalized (OR 1.19, 95%CI 0.15-9.47). In multivariable analysis, active cancer was associated with an increased risk of complications for patients treated at home (OR 7.95; 95%CI 1.48-42.82). For patients with active cancer, home treatment was not associated with the primary outcome (OR 1.19, 95%CI 0.15-9.74). CONCLUSIONS: Among patients treated at home, active cancer was a risk factor for complications, but among patients with active cancer, home treatment was not associated with adverse outcomes.

BACKGROUND: The severity of COVID-19 after SARS-CoV-2 infection is unpredictable. Angiotensin-converting enzyme-2 (ACE2) is the receptor responsible for coronavirus binding, while subsequent cell entry relies on priming by the serine protease TMPRSS2 (transmembrane protease, serine 2). Although renin-angiotensin-aldosterone-system (RAAS) blockers have been suggested to upregulate ACE2, their use in COVID-19 patients is now considered well tolerated. The aim of our study was to investigate parameters that determine COVID-19 severity, focusing on RAAS-components and variation in the genes encoding for ACE2 and TMPRSS2. METHODS: Adult patients hospitalized due to SARS-CoV-2 infection between May 2020 and October 2020 in the Haga Teaching Hospital were included, and soluble ACE2 (sACE2), renin, aldosterone (in heparin plasma) and polymorphisms in the ACE2 and TMPRSS2 genes (in DNA obtained from EDTA blood) were determined. MEASUREMENTS AND MAIN RESULTS: Out of the 188 patients who were included, 60 were defined as severe COVID-19 (ICU and/or death). These patients more often used antidiabetic drugs, were older, had higher renin and sACE2 levels, lower aldosterone levels and a lower aldosterone/renin ratio. In addition, they displayed the TMPRSS2-rs2070788 AA genotype less frequently. No ACE2 polymorphism-related differences were observed. Multivariate regression analysis revealed independent significance for age, sACE2, the aldosterone/renin ratio, and the TMPRSS2 rs2070788 non-AA genotype as predictors of COVID-19 severity, together yielding a C-index of 0.79. Findings were independent of the use of RAAS blockers. CONCLUSION: High sACE2, a low aldosterone/renin ratio and having the TMPRSS2 rs2070788 non-AA genotype are novel independent determinants that may help to predict COVID-19 disease severity. TRIAL REGISTRATION: retrospectively registered.

OBJECTIVE/BACKGROUND: Endovascular aneurysm repair (EVAR) may be associated with renal injury and more insight is needed into potential risk factors. The aim was to identify clinical, anatomical, and peri-procedural parameters as potential risk factors for the occurrence of acute kidney injury (AKI) and to evaluate chronic kidney disease (CKD) after EVAR. METHODS: A cohort of 212 consecutive patients who underwent elective EVAR for abdominal aortic aneurysm from January 2009 to October 2016 was included. A subgroup of 149 patients with 2 years follow-up was compared with a set of 135 non-operated aneurysm patients with smaller aneurysms (similar cardiovascular risk profile) to assess CKD. Primary outcomes were AKI (Acute Kidney Injury Network criteria) and CKD measured by estimated glomerular filtration rate (Kidney Disease Improving Global Outcomes guidelines). For AKI, candidate risk factors were identified by univariate and multivariate logistic regression analysis; for chronic renal function decline, risk factors were identified using Cox regression analysis. RESULTS: AKI occurred in 30 patients (15%). On multivariate analysis, the use of angiotensin II blocker (odds ratio [OR] 4.08, 95% confidence interval [CI] 1.38-12.07) and peri-operative complications (OR 3.12, 95% CI 1.20-8.10) were independent risk factors for AKI, whereas statin use was a protective factor (OR 0.19, 95% CI 0.07-0.52). EVAR resulted in a significant increase (23.5%) in the occurrence of CKD compared with the control group (6.7%; p <.001). On univariate and multivariate Cox regression the risk factors: aortic neck diameter (per mm increase) (hazard ratio [HR] 1.13, 95% CI 1.02-1.25), renal artery stenosis >50% (HR 2.24, 95% CI 1.05-4.79), and the occurrence of AKI (HR 2.19, 95% CI 0.99-4.85) were significant predictors of CKD. CONCLUSION: This study identified use of angiotensin II blockers and peri-operative complications as risk factors for AKI. In addition, the problem of renal function decline after EVAR is highlighted, which indicates that prolonged protective measures (e.g., in those patients at high risk) over time are needed to improve patient outcomes.
