Prognostic Value of Transaminases and Bilirubin Levels at Admission to Hospital on Disease Progression and Mortality in Patients with COVID-19—An Observational Retrospective Study

Introduction: Given the impact of COVID-19 on the world healthcare system, and the efforts of the healthcare community to find prognostic factors for hospitalization, disease progression, and mortality, the aim of the present study was to investigate the prognostic impact of transaminases and bilirubin levels at admission to hospital on disease progression and mortality in COVID-19 patients. Methods: Using the CoviCamp database, we performed a multicenter, observational, retrospective study involving 17 COVID-19 Units in southern Italy. We included all adult patients hospitalized for SARS-CoV-2 infection with at least one determination at hospital admission of aminotransaminases and/or total bilirubin. Results: Of the 2054 patients included in the CoviCamp database, 1641 were included in our study; 789 patients (48%) were considered to have mild COVID-19, 347 (21%) moderate COVID-19, 354 (22%) severe COVID-19, and 151 patients (9%) died during hospitalization. Older age (odds ratio (OR): 1.02; 95% confidence interval (CI) 1.01–1.03), higher Charlson comorbidity index (CCI) (OR 1.088; 95%CI 1.005–1.18), presence of dementia (OR: 2.20; 95% CI: 1.30–3.73), higher serum AST (OR: 1.002; 95% CI: 1.0001–1.004), and total bilirubin (OR: 1.09; 95% CI: 1.002–1.19) values were associated with a more severe clinical outcome. Instead, the 151 patients who died during hospitalization showed a higher serum bilirubin value at admission (OR 1.1165; 95% CI: 1.017–1.335); the same did not apply for AST. Discussion: Patients with COVID-19 with higher levels of AST and bilirubin had an increased risk of disease progression.

Impact of COVID-19 on digestive system: prevalence, clinical characteristics, outcome, and relation to the severity of COVID-19

Background

Coronavirus disease 2019 (COVID-19) is commonly associated with respiratory symptoms. However, gastrointestinal (GI) symptoms are increasingly recognized in COVID-19 patients. The aim is to study the prevalence and features of gastrointestinal manifestations in severe acute respiratory coronavirus 2 (SARS-CoV-2) infected patients and evaluate the outcome among the studied population.

Results

We enrolled adult patients with laboratory-confirmed COVID-19 admitted to Ain Shams University designated hospitals, Cairo, Egypt, from March 2021 to June 2021. The patients were assigned to a GI group and a non-GI group based on the presence or absence of one or more digestive symptoms. A total of 300 hospitalized COVID-19 patients were included, of which 104 (34.7%) had one or more digestive symptoms. They were compared with 196 COVID-19 patients without GI symptoms. The most common reported GI symptom was diarrhea (82.7%). GI symptoms' presence was higher in moderate cases. Patients with digestive symptoms presented for care later than those without (7.9±3.8 vs 7.4±7.2 days, P=0.5). Moreover, they have lower mortality, though non-significant (7.7 vs 12.8%, P=0.18). Patients with digestive symptoms had lower total leucocytic count (TLC), neutrophil count, neutrophil to lymphocyte ratio (NLR), platelet count, and higher serum sodium than those without digestive symptoms.

Conclusion

GI symptoms are prevalent among COVID-19 patients, and the most common was diarrhea. The presence of GI manifestations was not associated with increased mortality.
