ABSTRACT
Background: Although Brain Natriuretic Peptide (BNP) provides strong prognostic information of an unfavorable outcome in patients with acute heart failure (AHF), there is little information of its relevance as a biomarker for outcomes in COVID-19 and its complications Purpose: To evaluate the association of increased BNP levels with complications and in-hospital mortality in a cohort of hospitalized COVID-19 patients. Method(s): The study included COVID-19 patients with data on BNP levels included in the ISACS COVID-19 registry. The population was categorized according to the presence of peak BNP levels >=100 pg/mL during hospitalization. Primary outcomes included in-hospital mortality, AHF or acute respiratory failure (ARF, defined as PiO2/FiO2<300 mmHg or need for mechanical ventilation). Calculations were conducted using age and sex-adjusted multivariable logistic regression analyses. Results were also stratified according to presence or absence of cardiovascular disease (CVD) history. Differences between subgroups were verified for statistical significance using test for interaction. Result(s): Of the 1152 patients included in the study, 615 (53.4%) had elevated BNP levels. These subjects were older (69.9+/-13.8 vs 59.1+/-16.8, p-value<0.001), had higher rates of cardiovascular risk factors (82.9% vs 57.7%, p-value<0.001) and presented more frequently with a prior history of CVD (either ischemic heart disease, cerebrovascular disease, venous thromboembolism, atrial fibrillation or a history of revascularization) (50.1% vs 27.5%, p-value<0.001). No sex differences were observed. When considering outcomes, BNP levels >=100 pg/mL were associated with increased rates of in-hospital mortality (32.9% vs 4.9%, p-value<0.001), even after adjustment for demographic characteristics (OR: 7.35;95% CI: 4.75-11.40;p-value<0.001). High BNP levels were also strongly associated with an increased risk of AHF (OR 19.9;95% CI 8.6-45.9;pvalue< 0.001), a correlation that persisted both in patients with and without a prior CVD history (p for interaction=0.29). Of note, patients with elevated BNP also had a higher likelihood of developing ARF (OR 2.7;95% CI 2.1- 3.6;p-value<0.001), even in absence of AHF (OR 3.00;95% CI 2.20-4.1;p-value<0.001). Conclusion(s): In COVID-19, blood BNP level not only appears to be predictor of in-hospital mortality and AHF but was also independently associated with an increased risk of ARF. This finding supports the routine use of BNP in all patients admitted to hospital for COVID-19, regardless of a prior history of CVD.
ABSTRACT
Background: There are a range of traditional risk factors for COVID-19, but it is not well established if there are also psychiatric related risk factors. These factors could increase angiotensin-converting enzyme 2 expression and potentiate COVID-19 cell entry. Purpose: We aimed to assess if psychiatric disorders and antipsychotic treatments represent risk factors for COVID-19 worst outcomes. Methods: We describe the demographics, symptoms, therapeutic management, and survival outcomes of COVID-19 in the population who were admitted in a single academic hospital in Northern Italy between March 1 and June 30, 2020. Patients were determined to have COVID-19 if they had a positive SARS-CoV-19 swab. We used logistic regression analyses to control for confounding by concomitant risk factors for COVID-19 and for therapeutic management of comorbidities including psychiatric disorders and antipsychotic related drugs. Results: Among 609 patients, in-hospital death occurred in 120 (19.7%). A psychiatric disorder in the previous years was overrepresented (p<0.0001) in non-survivors (35.5%) in comparison with survivors (22.1%). Age and a history of hypertension were as well, established (p<0.005) risk factors for COVID-19 adverse outcomes: 80.6±11.4 vs 68±17.4 years and 70% vs 52% of people with hypertension in non-survivors vs survivors. Various pre-existing conditions were also associated (p<0.001) with increased risk of death, such as stroke or transient ischemic attacks, chronic obstructive pulmonary disease (COPD) and chronic kidney disease (CKD) (20% vs 8%, 35% vs 17%, and 24% vs 10%, respectively). We did not observe that prior use of angiotensin converting enzyme inhibitors or angiotensin receptor blockers were more prevalent in non-survivors compared with survivors. On the opposite, prior use of aspirin, P2Y receptor antagonists, and antipsychotic drugs was more common (p<0.001) in non-survivors compared with their counterparts (36% vs 21%, 12% vs 5%, and 28% vs 10%, respectively). After multivariable adjustment, use of antipsychotic drugs was associated with higher risks of in-hospital death (OR: 2.27;95% CI, 1.17- 4.4). Other independent predictors of death were older age (OR: 2.8;95% CI, 1.69-4.63), CKD (OR: 2.2;95% CI, 1.21-4.03) and COPD (OR: 2.04;95% CI, 1.22-3.42). Conclusions: Antipsychotic drugs might be an independent risk factor for COVID-19 adverse outcomes. Although preliminary, our findings have implications for clinical services as they provide crucial information for understanding who is at greatest risk for COVID-19.
