ABSTRACT
Clinical presentation is an undependable prognostic indicator of COVID-19 (COronaVIrus Disease 2019). So, a more objective predictor is needed to precisely evaluate and classify the prognosis. Immune dysregulation to lymphocytes, mainly T-lymphocytes, have been noticed between COVID-19 patients. The aim. This study was planned to determine the role of platelet-to-lymphocyte count ratio and neutrophil-to-lymphocyte ratio in assessment of COVID-19 prognosis. Methods. 70 hospitalized patients with confirmed COVID-19 were included in this study. All included patients underwent a consistent clinical, radiological and blood examination. Laboratory analysis was made by means of a commercially accessible kit. Blood cells ratios were computed by dividing their absolute counts. Results. Non-significant association was found between laboratory data and COVID-19 clinical severity. A significant association between CT classification and platelet-to-lymphocyte count ratio (higher value in L type;p = 0.001) was detected. Platelet-to-lymphocyte count ratio was significantly higher among intubated cases. However, Non-significant association was found between neutrophil-to-lymphocyte ratio and need of endotracheal intubation. Conclusion. Routine blood values are abnormal in patients with COVID-19. Platelet-to-lymphocyte count ratio ratios could be used as more meaningful biomarker than other values in predicting the prognosis of COVID-19. LMR helpful in COVID-19 severity.
ABSTRACT
The pandemic of COVID-19 infection is rapidly progressing to one of the most severe threats to human health. The different responses of the immune system in females and males to a range of infectious and inflammatory stimuli were investigated. We aimed to explore the association of sex with the course of infection among the hospitalized COVID-19 patients. This Comparative cross-sectional study was conducted on RT- PCR positive COVID-19 patients. Severe and critical patients who required hospital or ICU admission were included in the study. The total number of patients was 150 (75 males and 75 females) with mean age of 57Y±14.7. There was a statistical significance in age between both groups [mean ± SD: Males 60.5 (12.2), females 54 (15.3) (p=0:0.007)]. The prevalence of diabetes mellitus, hypertension, chronic kidney disease and ischemic heart disease was higher among males but without statistical significance. Consolidation was significantly more prevalent in female group (85.3% vs 61.3% in male group). The need of mechanical ventilation was higher in men, but with no statistical significance (44% Vs 32%, p=0.302). Also, mortality rate was higher (48%) in males than in females (37.3%), but with no statistical significance (p=0.262). During the COVID-19 infection, the risk factors of severe disease and progression to the need of mechanical ventilation support in addition to mortality rate are more prevalent among males. However, radiological patterns apart from consolidation, distribution of radiological abnormalities and CT severity score in both groups did not show significant sex difference.
