Background Being highly infectious disease, COVID-19 exhausts most of efficient healthcare systems worldwide. Simple and rapid risk stratification methods are mandatory to recognize severe patients. This study aims to highlight the simple available laboratory biomarkers of good predictive value for COVID-19 severity. Results Three hundred fifty-one COVID-19 positive patients admitted to two University Hospitals between the 1st of June and the 31st of July 2020 were retrospectively collected and classified to severe and non-severe COVID-19 patients according to need for ICU admission. All basic laboratory biomarkers at time of admission were recorded. Of included patients, 145 (41.3%) needed ICU admission. Anemia, leukocytosis, lymphopenia, NLR, and PLR together with liver enzymes, INR, ferritin, CRP, and D-dimer were significantly higher in patients needed ICU admission (p < 0.001). However, by applying multivariate logistic regression, only anemia, high NLR, high PLR, and high D-dimer levels showed significant risk for ICU admission with OR equal 3.6 (95% CI 1.8–7.0), 9.0 (95% CI 3.6–22.6), 3.0 (95% CI 1.3–7.1), and 2.5 (95% CI 1.3–4.7), respectively. Conclusion Anemia, increased neutrophil-to-lymphocyte ratio (> 8), platelet-to-lymphocyte ratio (> 192), and D-dimer level (> 0.9 mg\L) at time of admission could be simple available predictors for severe COVID-19 infection requiring ICU admission.
Background and aims: The coronavirus disease 19 (COVID-19) pandemic has spread rapidly around the globe with considerable morbidity and mortality. Coexistence of comorbidities with COVID-19 have consistently been reported as risk factors for unfavorable prognosis. We aim at this study to evaluate the impact of comorbidities in COVID-19 patients on the outcome and determine predictors of prolonged hospital stay, requisite for ICU admission or decease. Methods: Four hundreds and thirty nine adult patients who are admitted through (June and July 2020) in Assiut and Aswan University Hospitals were included in the study. All participants were diagnosed with COVID-19 according to Egyptian Ministry of Health guidance as definite case or Probable case. Detection of SARS-CoV-2 RNA was done by (TaqMan 2019-nCoV Control Kit v1 (Cat. No. A47532) supplied by QIAGEN, Germany on the Applied Biosystem 7500 Fast RT PCR System, USA. Results: Patients with comorbidities represented 61.7% of all cases. Constitutional symptoms especially myalgia and LRT symptoms such as dyspnea were significantly higher in patients with comorbidities (P < 0.05). Patients with comorbidities had significantly worse laboratory parameters. ICU admission was higher in patients with comorbidities (35.8%). Among different comorbidities 45.4% of CVD cases were admitted in ICU followed by DM cases (40.8%). Also, patients with comorbidities needed invasive mechanical ventilation more than those without comorbidity (31 vs. 10.7%, P<0.001). Significant lower frequency of recovery was found in COVID-19 patients with comorbidities (59% vs. 81%, P<0.001) and death rate was significantly higher in cases with comorbidities (P< 0.001). The survival rates in cases with pre-existing CVD and neurological diseases were lower than those without disease (P<0.002 and 0.001 respectively). Conclusion: Association of cardiovascular comorbid conditions including hypertension or neurological diseases together with COVID-19 infections carries higher risks of mortality. However, other comorbidities such as diabetes mellitus, chronic pulmonary or kidney diseases may also contribute to increased COVID-19 severity.
Background and Aim:Recently, a clear evidence suggests that non alcoholic fatty liver disease (NAFLD) is associated with an increased risk of incident atrial fibrillation (AF). Yet, the underlying pathogenesis is speculative. Thereby, we aimed to investigate the hypothesis that, interatrial thickness (IAST) and left atrial stiffness (LASt) might have mechanistic links between NAFLD and AF.Methods: Echocardiography and speckle-tracking assessment of left atrial function, transient elastography (TE) of the liver, basal ECG, and Holter monitoring were performed in 180 patients with (NAFLD) and 80 subjects without NAFLD.Results: Patients with NAFLD had higher values of IAST (P < 0.001), LASt (<0.001), and E/e′ ratio (<0.003) compared with controls. IAST was correlated with LASt (r = 0.413; P < 0.001). 15.6% of patients with NAFLD had AF. More so, patients with increased IAST/LASt had a higher incidence of AF (25%) vs 3.8% in those with normal IAST/LASt. The LASt and IAST increased significantly in those with AF compared with those without (P < 0.001). Patients who experienced AF had higher values (P < 0.01) of TE (kPa).The degree of liver stiffness TE (kPa) was correlated with both IAST and LASt (r = 461, r = 0.535; P < 0.001). Furthermore, multivariate regression analysis showed that LASt and IAST were independent predictors of incident AF in subjects with NAFLD.Conclusions: Our data suggest that increased IAST and LASt index are independently associated with incident atrial fibrillation in patients with NAFLD. Increased IAST and LASt index might provide mechanistic links between NAFLD and incident atrial fibrillation.

Rational: Recently, a new Post-COVID-19 Functional Status (PCFS) scale is recommended in the current COVID-19 pandemic. It is proposed that it could be used to display direct retrieval and the functional sequelae of COVID-19. Aim of the study: To assess the Post COVID-19 functional status in Egypt and to evaluate if age, gender, comorbidities have any effect on functional limitations in recovered COVID-19 patients. Patients and methods: A total of 444 registered confirmed COVID-19 patients were included. They were interviewed in our follow-up clinics or by calls and filled an Arabic translated PCFS scale in paper or online forms as well as their demographic and clinical data. Results: 80% of COVID-19 recovered cases have diverse degrees of functional restrictions ranging from negligible (63.1%), slight (14.4%), moderate (2%) to severe (0.5%) based on PCFS. Furthermore, there was a substantial variance between the score of PCFS with age (P= 0.003), gender (P= 0.014), the duration since the onset of the symptoms of COVID-19 (P <0.001), need for oxygen supplementation (P<0.001), need for ICU admittance (P= 0.003), previous periodic influenza vaccination (P<0.001), smoking status (P < 0.001) and lastly the presence of any comorbid disorder (P <0.001). Conclusions: Most of the COVID-19 recovered cases have diverse degrees of functional restrictions ranging from negligible to severe based on PCFS. These restrictions were affected by age, gender, periodic influenza vaccination, smoking, duration since symptoms onset, need for oxygen or ICU admittance, and lastly the presence of coexisting comorbidity.
