ABSTRACT
Background & Aims Gastrointestinal (GI) symptoms are present in 20% of patients with COVID-19. We studied the association of GI symptoms (in COVID-19 patients) with adverse outcomes and factors associated with poor outcomes in these patients. Methods The study cohort included 100,902 patients from the Cerner Real World Data (CRWD) COVID-19 Database of hospital encounters and emergency department (ER) visits with COVID-19 infection from December 1, 2019, to November 30, 2020. Multivariate analysis was used to study the effect of GI symptoms on adverse outcomes, and the factors associated with acute respiratory distress syndrome (ARDS), sepsis, and ventilator requirement or oxygen dependence in COVID-19 patients with GI symptoms. Results Patients with COVID-19 and GI symptoms were significantly more likely to have ARDS (OR 1.20, 95% CI 1.11, 1.29), sepsis (OR 1.19, 95% CI 1.14, 1.24), acute kidney injury (OR 1.30, 95% CI 1.24, 1.36), venous thromboembolism (OR 1.36, 95% CI 1.22, 1.52) or GI bleed (OR 1.62, 95% CI 1.47, 1.79);and less likely to experience cardiomyopathy (OR 0.87, 95% CI 0.77, 0.99) or death (OR 0.71, 95% CI 0.67, 0.75). Among those with GI symptoms, older age, higher Charlson comorbidity index scores, and use of proton pump inhibitors (PPI)/ H2 receptor antagonists (H2RA) were associated with higher mortality, ARDS, sepsis, and ventilator or oxygen requirement. Conclusion Patients with COVID-19 who have GI symptoms have overall worse in-hospital complications, but less cardiomyopathy and mortality. Older age, higher comorbidity scores, and the use of PPI and H2RA are associated with poor outcomes in these patients.
ABSTRACT
The COVID-19 pandemic has affected all people across the globe. Regional and community differences in timing and severity of surges throughout the pandemic can provide insight into risk factors for worse outcomes in those hospitalized with COVID-19. The study cohort was derived from the Cerner Real World Data (CRWD) COVID-19 Database made up of hospitalized patients with proven infection from December 1, 2019 through November 30, 2020. Baseline demographic information, comorbidities, and hospital characteristics were obtained. We performed multivariate analysis to determine if age, race, comorbidity and regionality were predictors for mortality, ARDS, mechanical ventilation or sepsis hospitalized patients with COVID-19. Of 100,902 hospitalized COVID-19 patients included in the analysis (median age 52 years, IQR 36–67;50.7% female), COVID-19 case fatality rate was 8.5% with majority of deaths in those ≥ 65 years (70.8%). In multivariate analysis, age ≥ 65 years, male gender and higher Charlson Comorbidity Index (CCI) were independent risk factors for mortality and ARDS. Those identifying as non-Black or non-White race have a marginally higher risk for mortality (OR 1.101, CI 1.032–1.174) and greater risk of ARDS (OR 1.44, CI 1.334–1.554) when compared to those who identify as White. The risk of mortality or ARDS was similar for Blacks as Whites. Multivariate analysis found higher mortality risk in the Northeast (OR 1.299, CI 1.22–1.29) and West (OR 1.26, CI 1.18–1.34). Larger hospitals also had an increased risk of mortality, greatest in hospitals with 500–999 beds (OR 1.67, CI 1.43–1.95). Advanced age, male sex and a higher CCI predicted worse outcomes in hospitalized COVID-19 patients. In multivariate analysis, worse outcomes were identified in small minority populations, however there was no difference in study outcomes between those who identify as Black or White.
ABSTRACT
Importance: Coronavirus disease 2019 (COVID-19) is a global pandemic and can involve the gastrointestinal (GI) tract, including symptoms like diarrhea and shedding of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in feces. Objective: To provide a pooled estimate of GI symptoms, liver enzyme levels outside reference ranges, and fecal tests positive for SARS-CoV-2 among patients with COVID-19. Data Sources: An electronic literature search was performed for published (using MEDLINE/PubMed and Embase) and preprint (using bioRxiv and medRxiv) studies of interest conducted from November 1, 2019, to March 30, 2020. Search terms included "COVID-19," "SARS-Cov-2," and/or "novel coronavirus." Study Selection: Eligible studies were those including patients with SARS-CoV-2 infection who reported GI symptoms. Data Extraction and Synthesis: Data on patients with GI symptoms (ie, diarrhea, nausea, or vomiting), liver enzyme level changes, and fecal shedding of virus were extracted. Quality of studies was examined using methodological index for nonrandomized studies. Pooled estimates (%) were reported with 95% CIs with level of heterogeneity (I2). Main Outcomes and Measures: Study and patient characteristics with pooled detection rates for diarrhea, nausea or vomiting, liver enzyme levels outside reference ranges, and SARS-CoV-2 positivity in feces tests were analyzed. Results: Of 1484 records reviewed, 23 published and 6 preprint studies were included in the analysis, with a total of 4805 patients (mean [SD] age, 52.2 [14.8] years; 1598 [33.2%] women) with COVID-19. The pooled rates were 7.4% (95% CI, 4.3%-12.2%) of patients reporting diarrhea and 4.6% (95% CI, 2.6%-8.0%) of patients reporting nausea or vomiting. The pooled rate for aspartate aminotransferase levels outside reference ranges was 20% (95% CI, 15.3%-25.6%) of patients, and the pooled rate for alanine aminotransferase levels outside reference ranges was 14.6% (95% CI, 12.8%-16.6%) of patients. Fecal tests that were positive for SARS-CoV-2 were reported in 8 studies, and viral RNA shedding was detected in feces in 40.5% (95% CI, 27.4%-55.1%) of patients. There was high level of heterogeneity (I2 = 94%), but no statistically significant publication bias noted. Conclusions and Relevance: These findings suggest that that 12% of patients with COVID-19 will manifest GI symptoms; however, SAR-CoV-2 shedding was observed in 40.5% of patients with confirmed SARS-CoV-2 infection. This highlights the need to better understand what measures are needed to prevent further spread of this highly contagious pathogen.
