Symptomatic, clinical and biomarker associations for mortality in hospitalized COVID-19 patients enriched for African Americans.

BACKGROUND AND AIMS: Initial reports on US COVID-19 showed different outcomes in different races. In this study we use a diverse large cohort of hospitalized COVID-19 patients to determine predictors of mortality. METHODS: We analyzed data from hospitalized COVID-19 patients (n = 5852) between March 2020- August 2020 from 8 hospitals across the US. Demographics, comorbidities, symptoms and laboratory data were collected. RESULTS: The cohort contained 3,662 (61.7%) African Americans (AA), 286 (5%) American Latinx (LAT), 1,407 (23.9%), European Americans (EA), and 93 (1.5%) American Asians (AS). Survivors and non-survivors mean ages in years were 58 and 68 for AA, 58 and 77 for EA, 44 and 61 for LAT, and 51 and 63 for AS. Mortality rates for AA, LAT, EA and AS were 14.8, 7.3, 16.3 and 2.2%. Mortality increased among patients with the following characteristics: age, male gender, New York region, cardiac disease, COPD, diabetes mellitus, hypertension, history of cancer, immunosuppression, elevated lymphocytes, CRP, ferritin, D-Dimer, creatinine, troponin, and procalcitonin. Use of mechanical ventilation (p = 0.001), shortness of breath (SOB) (p < 0.01), fatigue (p = 0.04), diarrhea (p = 0.02), and increased AST (p < 0.01), significantly correlated with death in multivariate analysis. Male sex and EA and AA race/ethnicity had higher frequency of death. Diarrhea was among the most common GI symptom amongst AAs (6.8%). When adjusting for comorbidities, significant variables among the demographics of study population were age (over 45 years old), male sex, EA, and patients hospitalized in New York. When adjusting for disease severity, significant variables were age over 65 years old, male sex, EA as well as having SOB, elevated CRP and D-dimer. Glucocorticoid usage was associated with an increased risk of COVID-19 death in our cohort. CONCLUSION: Among this large cohort of hospitalized COVID-19 patients enriched for African Americans, our study findings may reflect the extent of systemic organ involvement by SARS-CoV-2 and subsequent progression to multi-system organ failure. High mortality in AA in comparison with LAT is likely related to high frequency of comorbidities and older age among AA. Glucocorticoids should be used carefully considering the poor outcomes associated with it. Special focus in treating patients with elevated liver enzymes and other inflammatory biomarkers such as CRP, troponin, ferritin, procalcitonin, and D-dimer are required to prevent poor outcomes.

Gastrointestinal manifestations in American minority population with COVID-19.

BACKGROUND: The spectrum of gastrointestinal (GI) injuries by the SARS-CoV-2 remain largely unknown. Ethnicity data is missing or unspecified. We analyzed GI involvement in American minority patients with COVID-19 infection. METHODS: Retrospective study of hospitalized patients with confirmed COVID-19 in March-April 2020. RESULTS: 183 patients included: 114 (62.30%) African-Americans, 58 (31.69%) Hispanics and 11 (6.01%) Asians. 73 females, 110 males; mean age 64.77, mean BMI 29.03 (50.82%); GI manifestations upon presentation: anorexia (29.51%), diarrhea (22.40%), nausea/vomiting (18.03%), abdominal pain (9.84%). No difference observed between three ethnical groups for GI symptoms and liver function tests. C Reactive Protein (CPR) (P=0.008), Lactate (P=0.03) and Prothrombin Time (PT) (P=0.03) were significantly elevated in patients without GI symptoms. No difference was observed for other laboratory tests. Patients with severe disease course/intubated had higher levels of Aspartate Transaminase (AST) (109.17 vs 53.97, P=0.018), Alanine Transaminase (ALT) (79.53 vs 40.03, P=0.02) and total bilirubin (0.82 vs 0.60, P=0.03) vs non-intubated patents as well as body temperature (101.38 vs 100.70, p=0.0006), CRP (24.06 v 15.96, P=0.019) and lactate (3.28 vs 2.13, P=0.009). There was no correlation between severity of the disease and GI symptoms, PT, platelets and albumin. However, CRP and lactate were markedly elevated in deceased vs survived patients: (27.09 vs 16.39, P=0.008) and (3.33 vs 2.10 P=0.005) respectively. CONCLUSIONS: ~ 50% of patients presented with GI symptoms and they had lower levels of inflammatory markers, better liver synthetic function, indicating less overall inflammatory response and direct viral damage. Our results suggest that SARS-CoV-2 virus targets GI tract along with the lung tissue, and the degree of hepatocyte damage correlated well with more severe disease.

Does C reactive protein/Albumin ratio have prognostic value in patients with COVID-19.

INTRODUCTION: There is paucity of data regarding C reactive protein/Albumin (CRP/Alb) ratio in patients with SARS-CoV-2 infection. We aimed to evaluate the significance of CRP/Alb ratio in COVID-19 patients. METHODOLOGY: Patients hospitalized between March - April 2020 with COVID-19, who had CRP and Albumin levels documented within 24 hours from admission were retrospectively analyzed. Unpaired Student's t-test was used for continuous and Pearson Chi-square (χ²) test for categorical variables. Univariate and multivariate logistic regression models were developed to assess the relationship between CRP/Alb and mortality. Nonparametric correlations were calculated using Spearman's Rho correlation coefficient. RESULTS: 75 patients were included. Mean age was 62.92, 26 females (34.67%) and 49 males (65.33%), mean Body Mass Index (BMI) 29.86, mean body temperature 101.3 and mean length of stay (LOS) was 14.80 days. 24 (32%) patients required invasive mechanical ventilation and 51 (68%) did not, mean CRP/Alb ratio was 6.89 and 4.7 respectively (p = 0.036). 15 (20%) patients died, 60 (80%) survived and the mean CRP/Alb difference between these groups was also statistically significant (7.74 vs 4.83, p = 0.02). LOS (OR 0.71, 95% CI 0.57.-0.88, p < 0.001) and BUN (OR 1.04, 95% CI 1.01.-1.07, p = 0.006) were independent predictors of mortality by multivariate logistic regression, whereas CRP/Alb (OR 1.21, 95% CI 0.96.-1.51, p = 0.06) was not. CONCLUSIONS: CRP/Alb ratio could be useful as a prognostic indicator of disease severity in COVID-19, but we could not corroborate its potential to predict mortality. The work was conducted at Columbia University College of Physicians and Surgeons at Harlem Hospital.

New York Inner City Hospital COVID-19 Experience and Current Data: Retrospective Analysis at the Epicenter of the American Coronavirus Outbreak.

BACKGROUND: In the midst of the coronavirus disease pandemic, emerging clinical data across the world has equipped frontline health care workers, policy makers, and researchers to better understand and combat the illness. OBJECTIVE: The aim of this study is to report the correlation of clinical and laboratory parameters with patients requiring mechanical ventilation and the mortality in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). METHODS: We did a review of patients with SARS-CoV-2 confirmed infection admitted and managed by our institution during the last month. Patients were grouped into intubated and nonintubated, and subgrouped to alive and deceased. A comprehensive analysis using the following parameters were performed: age, sex, ethnicity, BMI, comorbidities, inflammatory markers, laboratory values, cardiac and renal function, electrocardiogram (EKG), chest x-ray findings, temperature, treatment groups, and hospital-acquired patients with SARS-CoV-2. RESULTS: A total of 184 patients were included in our study with ages ranging from 28-97 years (mean 64.72 years) and including 73 females (39.67%) and 111 males (60.33%) with a mean BMI of 29.10. We had 114 African Americans (61.96%), 58 Hispanics (31.52%), 11 Asians (5.98%), and 1 Caucasian (0.54%), with a mean of 1.70 comorbidities. Overall, the mortality rate was 17.39% (n=32), 16.30% (n=30) of our patients required mechanical ventilation, and 11.41% (n=21) had hospital-acquired SARS-CoV-2 infection. Pertinent and statistically significant results were found in the intubated versus nonintubated patients with confirmed SARS-CoV-2 for the following parameters: age (P=.01), BMI (P=.07), African American ethnicity (P<.001), Hispanic ethnicity (P=.02), diabetes mellitus (P=.001), creatinine (P=.29), blood urea nitrogen (BUN; P=.001), procalcitonin (P=.03), C-reactive protein (CRP; P=.007), lactate dehydrogenase (LDH; P=.001), glucose (P=.01), temperature (P=.004), bilateral pulmonary infiltrates in chest x-rays (P<.001), and bilateral patchy opacity (P=.02). The results between the living and deceased subgroups of patients with confirmed SARS-CoV-2 (linking to or against mortality) were BMI (P=.04), length of stay (P<.001), hypertension (P=.02), multiple comorbidity (P=.045), BUN (P=.04), and EKG findings with arrhythmias or blocks (P=.02). CONCLUSIONS: We arrived at the following conclusions based on a comprehensive review of our study group, data collection, and statistical analysis. Parameters that were strongly correlated with the need for mechanical ventilation were younger age group, overweight, Hispanic ethnicity, higher core body temperature, EKG findings with sinus tachycardia, and bilateral diffuse pulmonary infiltrates on the chest x-rays. Those intubated exhibited increased disease severity with significantly elevated levels of serum procalcitonin, CRP, LDH, mean glucose, creatinine, and BUN. Mortality was strongly correlated with BMI, African American ethnicity, hypertension, presence of multiple comorbidities (with a mean of 2.32), worsening renal function with acute kidney injury or acute chronic kidney injury, and EKG findings of arrhythmias and heart blocks.
