ABSTRACT
Hepatocellular carcinoma (HCC) remains one of the most common malignancies and the third cause of cancer-related death worldwide, with surgery being the best prognostic tool. Among the well-known causative factors of HCC are chronic liver virus infections, chronic virus hepatitis B (HBV) and chronic hepatitis virus C (HCV), aflatoxins, tobacco consumption, and non-alcoholic liver disease (NAFLD). There is a need for the development of efficient molecular markers and alternative therapeutic targets of great significance. In this review, we describe the general characteristics of HCC and present a variety of targeted therapies that resulted in progress in HCC therapy.

BACKGROUND: Severe COVID-19 pneumonia requiring intensive care treatment remains a clinical challenge to date. Dexamethasone was reported as a promising treatment option, leading to a reduction of mortality rates in severe COVID-19 disease. However, the effect of dexamethasone treatment on cardiac injury and pulmonary embolism remains largely elusive. METHODS: In total 178 critically ill COVID-19 patients requiring intensive care treatment and mechanical ventilation were recruited in three European medical centres and included in the present retrospective study. One hundred thirteen patients (63.5%) were treated with dexamethasone for a median duration of 10 days (IQR 9-10). Sixty five patients (36.5%) constituted the non-dexamethasone control group. RESULTS: While peak inflammatory markers were reduced by dexamethasone treatment, the therapy also led to a significant reduction in peak troponin levels (231 vs. 700% indicated as relative to cut off value, p = 0.001). Similar, dexamethasone resulted in significantly decreased peak D-Dimer levels (2.16 mg/l vs. 6.14 mg/l, p = 0.002) reflected by a significant reduction in pulmonary embolism rate (4.4 vs. 20.0%, p = 0.001). The antithrombotic effect of dexamethasone treatment was also evident in the presence of therapeutic anticoagulation (pulmonary embolism rate: 6 vs. 34.4%, p < 0.001). Of note, no significant changes in baseline characteristics were observed between the dexamethasone and non-dexamethasone group. CONCLUSION: In severe COVID-19, anti-inflammatory effects of dexamethasone treatment seem to be associated with a significant reduction in myocardial injury. Similar, a significant decrease in pulmonary embolism, independent of anticoagulation, was evident, emphasizing the beneficial effect of dexamethasone treatment in severe COVID-19.
ABSTRACT
BACKGROUND/AIM: Eosinophils are blood cells responsible for response against parasites and allergens. Eosinophil to lymphocyte ratio (ELR) is a biomarker for inflammatory conditions. Our aim was to evaluate the role of eosinophils and ELR in COVID-19 patients. PATIENTS AND METHODS: The study included 96 patients hospitalized with COVID-19. They were classified into moderate to severe cases and critical cases. Eosinophils and ELR were determined in both groups, in patients that died or survived and were correlated to duration of hospitalization. RESULTS: There was a statistically significant decrease in eosinophils and ELR between patients that died and patients that survived (p<0.05), and in mean values of the two biomarkers (p<0.05 for eosinophils and p<0.05 for ELR) between patients hospitalized for more or less than 15 days among those with moderate to severe disease. CONCLUSION: Lower eosinophil counts and ERL could probably predict worse outcome in COVID-19 patients.
