Background and study aim: Baveno VI consensus recommended the use of noninvasive predictors of EV to avoid unnecessary endoscopies. Von Willbrand factor (VWF) and VITRO score, (VWF/ platelet count), are both correlated to liver cirrhosis and fibrosis. The aim of this study was to evaluate the role of VWF and VITRO score as predictors of esophageal varices and their bleeding.Patients and Methods: Seventy seven patients were included in this study. They were randomly selected from cirrhotic patients admitted to endoscopy unit for the first time. They were allocated into two groups; group I: patients who have esophageal varices, group II: patients with no esophageal varices.Results: VWF Ag and VITRO score were significantly higher in the varices group (group I). VWF Ag level was 169.3±20.2 in group I vs 146.8±35.5 µg/dL in group II p<0.001. VITRO score was 2.2±1.1 in group I vs 1.6±0.7 µg/10 8 platelet p=0.05. We found that at cut off value of 153% VWF can predict the presence of EV with sensitivity 88.1% and specificity of 61.1% and AUC= 0.66 p=0.04. VITRO score can predict the presence of varices with sensitivity of 69.5% and specificity of 50% at a cut off value 1.5 AUC=0.065 P=0.05. Conclusion:VWF and VITRO score rise significantly in patients with esophageal varices. Both markers can be reliable in prediction of the presence of EV's. VWF Ag can be reliable marker in prediction of risky and bleeding varices.

In late 2019, a novel coronavirus, now designated SARS-CoV-2, emerged and was identified as the cause of an outbreak of acute respiratory illness in Wuhan, a city in China, named as COVID-19. Since then the waves of the virus exponentially hit many countries around the globe with high rates of spread associated with variable degrees of morbidity and mortality. The WHO announced the pandemic state of the infection in March 2020 and by June 1st 2020 more than 6 million individuals and more than 370 thousands case fatalities were documented worldwide. In this article, we discussed many aspects regarding this emerged infection based on the available evidence aiming to help clinician to improve not only their knowledge but also their practices toward this infection.

Background: Coronavirus disease 2019 (COVID-19) may lead to immunosuppression, leaving patients vulnerable to secondary invasive fungal infection like mucormycosis. The present study aimed to determine whether there are any risk factors associated with mortality in mucormycosis among COVID-19 patients. Patients and Methods: Patients with COVID-19 diagnosed with mucormycosis who received treatment at University Hospitals were included in the study. Complete blood count (CBC), glycated hemoglobin (HBA1c), C-reactive protein (CRP), serum albumin level, creatinine, ferritin levels, lactate dehydrogenase (LDH), D-dimer and histopathological observations were performed for all participants’ specimens. Results: The number (N) of patients included in the study was 46. About 85 % (39/46) of patients had post-COVID-19 syndrome and the other 7 cases were in the active phase of the disease. CRP, serum ferritin, D-dimer, CRP/albumin ratio and CRP/absolute lymphocyte counts were statistically significant (P<0.05) within non-survivors as compared to survivors. After analysis of multivariate analysis that patients had oxygen support, while elevated CRP/albumin ratios were independent predictors of mortality in COVID-19 patients associated with mucormycosis. Conclusions: Mucormycosis can be caused by immunosuppression conditions associated with COVID-19 infection. Oxygen levels and C-reactive protein/albumin are independent predictors of mortality and morbidity in post COVID-19 patients.
