The COVEG score to predict severity and mortality among hospitalized patients with COVID-19.

INTRODUCTION: COVID-19 severity and mortality predictors could determine admission criteria and reduce mortality. We aimed to evaluate the clinical-laboratory features of hospitalized patients with COVID-19 to develop a novel score of severity and mortality. METHODOLOGY: This retrospective cohort study was conducted using data from patients with COVID-19 who were admitted to five Egyptian university hospitals. Demographics, comorbidities, clinical manifestations, laboratory parameters, the duration of hospitalization, and disease outcome were analyzed, and a score to predict severity and mortality was developed. RESULTS: A total of 1308 patients with COVID-19, with 996 (76.1%) being moderate and 312 (23.9%) being severe cases, were included. The mean age was 46.5 ± 17.1 years, and 61.6% were males. The overall mortality was 12.6%. Regression analysis determined significant predictors, and a ROC curve defined cut-off values. The COVEG severity score was defined by age ≥ 54, D-dimer ≥ 0.795, serum ferritin ≥ 406, C-reactive protein ≥ 30.1, and neutrophil: lymphocyte ratio ≥ 2.88. The COVEG mortality score was based on COVEG severity and the presence of cardiac diseases. Both COVEG scores had high predictive values (area under the curve 0.882 and 0.883, respectively). CONCLUSIONS: COVEG score predicts the severity and mortality of patients with COVID-19 accurately.

Impact of pre-transplant infection management on the outcome of living-donor liver transplantation in Egypt.

BACKGROUND AND AIM: Liver transplantation (LT) has emerged as an established therapeutic option for patients with chronic liver disease. Patients with end-stage liver disease are at high risk of infection with multidrug-resistant organisms, which may affect the outcome of LT. The aim of this study was to evaluate the impact of pre-transplant infection on the outcome of living-donor LT. METHODS: Prospective follow-up was done for 50 patients with chronic liver disease who had had LT performed from September 2013 to December 2017. We divided patients into group 1 (patients who had had infection within 3 months before transplantation with adequate treatment [n=20]), and group 2 (patients without infection [n=30]). Both groups were followed for 4 months post-operatively. RESULTS: Patients with high Model for End-Stage Liver Disease scores were more susceptible to infection pre- and post-operatively, and chest infection was the most common infection pre-transplant. There were no significant statistical differences regarding hospital and ICU stay and post-operative course between the groups, but the mortality rate was higher in group 1 (40%) than in group 2 (23.3%), and the causes of mortality in the group 1 were mainly due to medical causes (infections and sepsis, 75%) versus 28.6% in group 2. CONCLUSION: Liver-cell failure and concomitant infection 3 months before LT with adequate treatment had no significant statistical differences regarding hospital, ICU stay, or medical complications, but post-operative infection and mortality rate were more frequent in group 1 and the causes of mortality were mainly medical.
