ABSTRACT
Background: Pretreatment and post-treatment performances of noninvasive fibrosis indices were determined in patients with chronic hepatitis B. Method: This was a retrospective, single-center study. Results: The best area under the receiver operating characteristic curve values were detected for aspartate aminotransferase-to-alanine aminotransferase ratio (0.685) for ≥F2, Fibrosis Index (FI; 0.703) for ≥F3; FI (0.872) for ≥F4 and FI (0.864) for cirrhosis. After antiviral treatment, the best area under the receiver operating characteristic curve values were detected in aspartate aminotransferase-to-alanine aminotransferase ratio (0.615) for ≥F2; in FI based on four factors (FIB-4; 0.634) for ≥F3; in FIB-4 (0.678) for ≥F4 and in FIB-4 (0.814) for cirrhosis. Conclusion: FIB-4 and FI showed better performance in defining advanced fibrosis (≥F4) and cirrhosis.

BACKGROUND: COVID-19 causes clinical manifestations ranging from asymptomatic infection to multi-organ failure. It is reported that those with severe disease have higher anti-SARS-CoV-2 antibody titers compared to asymptomatic or mild cases. We evaluated the correlation of antibody responses with laboratory and clinical indicators in COVID-19 patients. METHODS: Seventy-nine male and 66 female patients (mean age: 39) with at least one positive SARS-CoV-2 RT-PCR test and SARS-CoV-2 IgG antibody result after acute infection were included. RESULTS: Seventy-six (52%), 45 (31%), and 24 (17%) patients had mild, moderate, and severe clinical findings, respectively. Patients with high body mass index and advanced age had significantly more severe disease (p < 0.001). A significant correlation was found between the increase in lymphopenia, C-reactive protein, ferritin, D-dimer, and lactate dehydrogenase and the severity of clinical findings (p = 0.0001). SARS-CoV-2 IgG antibody test was positive in 128 (88.3%) patients. A significant correlation was found between disease severity and antibody levels in the comparison of all groups (p < 0.001). CONCLUSIONS: Long-term monitoring of immune responses will be required to determine the appropriate time for the administration of new vaccines.

Background: The aim was to explore a novel risk score to predict mortality in hospitalized patients with COVID-19 pneumonia. Methods: This was a retrospective, multicenter study. Results: A total of 1013 patients with COVID-19 were included. The mean age was 60.5 ± 14.4 years, and 581 (57.4%) patients were male. In-hospital death occurred in 124 (12.2%) patients. Multivariate analysis revealed peripheral capillary oxygen saturation (SpO2), albumin, D-dimer and age as independent predictors. The mortality score model was given the acronym SAD-60, representing SpO2, Albumin, D-dimer, age ≥60 years. The SAD-60 score (0.776) had the highest area under the curve compared with CURB-65 (0.753), NEWS2 (0.686) and qSOFA (0.628) scores. Conclusion: The SAD-60 score has a promising predictive capacity for mortality in hospitalized patients with COVID-19.
