Overview
Brief Summary
- ry outcome includes the correlation between lymphocyre /neurtophll ratio (LNR) and mortality rate during hospital stay in the ICU admitted COVID 19 patients.
- ry outcome(s) include the LNR and its correlation with ICU stay, the need for mechanical ventilation, renal impairment.
Detailed Description
In December 2019,the COVID-19 virus has been mainly breaking out in Wuhan in China as pneumonia affecting patients . Common clinical features During hospitalization started to appear including acute respiratory infection , inflammatory reaction , fever, pneumonia, cough, fatigue , anosmia . The patient known suspected if he has a clinical picture of viral pneumonia, exposure history, and radiographic findings \[CT\] or \[MRI\] chest consistent with COVID-19 pneumonia. the gold standard and the Final diagnosis (PCR) positivity for the presence of coronavirus . The immune response to respiratory infection causes neutrophils to collect inside the lung especially the alveoli. Neutrophils aggregation may lead to collateral tissue damage and cytotoxicity. According to Previous studies apoptosis of lymphocytes occurred due to the release of anti-inflammatory cytokines resulting in lymphopenia. high levels of circulating neutrophils have been demonstrated in COVID-19 patients( A lot of literatures and studies have demonstrated the value of what is called neutrophil/ lymphocyte ratio (LNR) as a simple prognostic ratio correlated to morbidity and mortality. Up to our knowledge, there is no study utilized such ratio in COVID-19 ICU admitted patients, so that, this study has been built
