Objective The role of treatment with renin-angiotensin-aldosterone system blockers at the onset of COVID-19 infection is not known in geriatric population. The aim of this study was to assess the relationship between angiotensin receptor blockers (ARB) and an ACE inhibitor (ACEI) use and in-hospital mortality in geriatric patients hospitalized for COVID-19. Design This observational retrospective study was conducted in a French geriatric department. Patients were included between March 17 and April 18, 2020. Setting and Participants: All consecutive 201 patients hospitalized for COVID-19 (confirmed by RT-PCR methods) were included. All non-deceased patients had 30 days of follow-up and no patient was lost to follow-up. Methods Demographic, clinical, biological data and medications were collected. In-hospital mortality of patients treated or not by ACEI/ARB was analyzed using multivariate Cox models. Results Mean age of the population was 86.3 (8.0) years old, 62.7% of patients were institutionalized, 88.6% had dementia and 53.5% had severe disability (ADL score < 2). Sixty-three patients were treated with ACEI/ARB and 138 were not. Mean follow-up was 23.4 (10.0) days, 66 (33.8%) patients died after an average of 10.0 days (6.0). Lower mortality rate was observed in patients treated with ACEI/ARB compared with patients not treated with ARB nor ACEI (22.2% (14) vs. 37.7% (52), HR = 0.54 (95% CI = 0.30-0.97), p=0.03). In a multivariate Cox regression model including age, sex, ADL score, Charlson index, renal function, dyspnea, CRP and white blood cells count, use of ACEI/ARB was significantly associated with lower in-hospital mortality (HR = 0.52 (0.27−0.99), p=0.048). Conclusion and Implications In very old subjects hospitalized in geriatric settings for COVID-19, mortality was significantly lower in subjects treated with ARB or ACEI prior to the onset of infection. The continuation of ACEI/ARB therapy should be encouraged during periods of coronavirus outbreak in older subjects.

Objective: Assessment of intravascular volume status to ensure optimization before hospital discharge could significantly reduce readmissions. It is difficult to evaluate congestion on clinical signs during an episode of acute heart failure (ADHF) in elderly patients.Hypothesis: There is an association between various volume overload parameters in patients older than 75 years. Methods:We performed a single-center prospective longitudinal study of patients older than 75 years hospitalized for acute heart failure. We analyzed the association between congestion assessment based on clinical signs, inferior vena cava (IVC) diameter measured by ultrasound, biological evaluation with N terminal pro brain natriuretic peptide (NT-proBNP), and estimated plasma volume (EPV) during decongestive therapy. We also monitored changes in renal function.Results: Fifty consecutive ADHF patients (85.2 ± 5.9 years, 68% female) were included in the study. At admission, a dilated, noncompliant IVC was found in all patients. The strongest correlations between different parameters of volume overload estimation were found between IVC and jugular vein distention (r = .8; p < .001), then IVC and oedema (r = .6; p < .001), IVC and crackles (r = .3; p < .036), then IVC and NT-proBNP (r = .3; p = .02). There was no correlation between EPV and signs of congestion. Patients who had no congestive signs on clinical or IVC examination at Day 2, more often presented with acute renal failure. Conclusion:In ADHF patients older than 75 years, clinical and IVC evaluation of intravascular congestion correlate well. The concomitant assessment of clinical signs and IVC may prevent depletion-related renal failure.
