Relation Between Lab Finding and COVID-19 Severity

Study Overview
=================
Brief Summary
-----------------
Severe acute respiratory syndrome coronavirus 2 (COVID-19) poses substantial challenges for health care systems. With a vastly expanding amount of publications on COVID-19, clinicians need evidence synthesis to produce guidance for handling patients with COVID-19.

Detailed Description
-----------------
. Conavirus belongs to the subfamily of Ortho-coronavirinae in the family of Coronaviridae and the Order Nidovirales. In 2003, a SARS-CoV had caused the out- break of severe acute respiratory syndrome. In December 2019, an unknown viral pneumonia out- break has been reported. Finally, a novel coronavirus was detected, isolated virus was termed as SARS-CoV2, characterized as highly contagious and deadly. By the end of February 2020, more than 78,631 cases infected with SARS-CoV-2, and more than 2747 deaths were confrmed in China, and the COVID-19 has been declared a pan- demic by World Health Organization. For those infected by SARS-CoV-2, some of the patients didnot show hypoxemia or respiratory stress during the course of COVID-19, indicating a multifaceted disease of SARS-CoV-2 infection. Therefore, one reliable and convenient biomarker is needed to predict the severity of COVID-19 pneumonia. Recently, several studies have reported that C-reactive protein (CRP) is positively asso-ciated with severe dengue infection, and patients with higher plasma CRP in the initial period of dengue, are at higher risk to develop plasma leakage. We examined which routine laboratory tests are associated with severe COVID-19 disease, and the relation between the laboratory results and the security of COVID19 diasease, in two of large Upper Egypt medical centers, which are Aswan University and assiut university hospitals.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Patients with COVID-19<br>The patients will be subjected to to laboratory analyses, a number of hematological, immunological and biochemical parameters like total leucocytic count and differential count of CBC, ESR, D- dimer levels in plasma, CRP, serum urea and creatinine levels, serum levels of AST, ALT liver enzymes, serum ferritin levels Also, CT scan of chest, clinical assessment and the severity and course of the disease. | Diagnostic Test: D-dimer,CBC.ESR,CRP,<br>* Complete blood count (for patients and control subjects): was done on CELL-DYN 3700 (Abbott-Germany) and blood film was stained by leishman staining, the morphology of red blood cells. CRP titre estimation by latix method .ESR erythrocyte sedimentation rate estimation (1:5) by Westerngreen tube method.<br>Diagnostic Test: Liver function tests ,serum ferritin and PCR for COVID-19 .<br>* Serum ferritin was performed for all subjects on Modular P auto analyzer (Roche Diagnostics, Mannheim, Germany), • Liver function tests ( aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase) and kidney funcrion were performed for all subjects on Modular P auto analyzer (Roche Diagnostics, Mannheim, G ermany),<br>|
