Background: Patients critically ill with coronavirus disease-2019 (COVID-19) feature hyperinflammation, and the associated biomarkers may be beneficial for risk stratification. We aimed to investigate the association between several biomarkers, including serum C-reactive protein (CRP), procalcitonin (PCT), D-dimer, and serum ferritin, and COVID-19 severity. Methods: We performed a comprehensive systematic literature search through electronic databases. The outcome of interest for this study was the composite poor outcome, which comprises mortality, acute respiratory distress syndrome, need for care in an intensive care unit, and severe COVID-19. Results: A total of 5350 patients were pooled from 25 studies. Elevated CRP was associated with an increased composite poor outcome [risk ratio (RR) 1.84 (1.45, 2.33), p < 0.001; I2: 96%] and its severe COVID-19 (RR 1.41; I2: 93%) subgroup. A CRP ⩾10 mg/L has a 51% sensitivity, 88% specificity, likelihood ratio (LR) + of 4.1, LR- of 0.5, and an area under curve (AUC) of 0.84. An elevated PCT was associated with an increased composite poor outcome [RR 3.92 (2.42, 6.35), p < 0.001; I2: 85%] and its mortality (RR 6.26; I2: 96%) and severe COVID-19 (RR 3.93; I2: 63%) subgroups. A PCT ⩾0.5 ng/ml has an 88% sensitivity, 68% specificity, LR+ of 2.7, LR- of 0.2, and an AUC of 0.88. An elevated D-dimer was associated with an increased composite poor outcome [RR 2.93 (2.14, 4.01), p < 0.001; I2: 77%], including its mortality (RR 4.15; I2: 83%) and severe COVID-19 (RR 2.42; I2: 58%) subgroups. A D-dimer >0.5 mg/L has a 58% sensitivity, 69% specificity, LR+ of 1.8, LR- of 0.6, and an AUC of 0.69. Patients with a composite poor outcome had a higher serum ferritin with a standardized mean difference of 0.90 (0.64, 1.15), p < 0.0001; I2: 76%. Conclusion: This meta-analysis showed that an elevated serum CRP, PCT, D-dimer, and ferritin were associated with a poor outcome in COVID-19.

Background: Complications of coronavirus disease 2019 (COVID-19) include coagulopathy. We performed a meta-analysis on the association of COVID-19 severity with changes in hemostatic parameters. Methods: Data on prothrombin time (PT), activated partial thromboplastin time (aPTT), D-Dimer, platelets (PLT), or fibrinogen in severe versus mild COVID-19 patients, and/or in non-survivors to COVID-19 versus survivors were systematically searched. The standardized mean difference (SMD) was calculated. Results: Sixty studies comparing 5487 subjects with severe and 9670 subjects with mild COVID-19 documented higher PT (SMD: 0.41; 95%CI: 0.21, 0.60), D-Dimer (SMD: 0.67; 95%CI: 0.52, 0.82), and fibrinogen values (SMD: 1.84; 95%CI: 1.21, 2.47), with lower PLT count (SMD: −0.74; 95%CI: −1.01, −0.47) among severe patients. Twenty-five studies on 1511 COVID-19 non-survivors and 6287 survivors showed higher PT (SMD: 0.67; 95%CI: 0.39, 0.96) and D-Dimer values (SMD: 3.88; 95%CI: 2.70, 5.07), with lower PLT count (SMD: −0.60, 95%CI: −0.82, −0.38) among non-survivors. Regression models showed that C-reactive protein values were directly correlated with the difference in PT and fibrinogen. Conclusions: Significant hemostatic changes are associated with COVID-19 severity. Considering the risk of fatal complications with residual chronic disability and poor long-term outcomes, further studies should investigate the prognostic role of hemostatic parameters in COVID-19 patients.

Abstract As per the indicated need in literature, we conducted a systematic review and meta-analysis to characterize inflammatory markers of MIS-C patients with COVID-19, Kawasaki disease (KD), and coronary artery abnormalities. We searched nine databases for studies on inflammatory markers of MIS-C. After quality check, data were pooled using a fixed- or random-effects model. Inflammatory markers included white blood cell count (WBC) or leukocytes, absolute lymphocyte count (ALC), absolute neutrophil count (ANC), platelet count (PLT), C-reactive protein (CRP), procalcitonin (PCT), ferritin, D-dimer, lactate dehydrogenase (LDH), fibrinogen and erythrocyte sedimentation rate (ESR) for comparisons by severity and age. Twenty studies with 2,990 participants yielded 684 MIS-C patients. Compared to non-severe COVID-19 patients, MIS-C patients had lower ALC and higher ANC, CRP and D-dimer levels. Compared to severe COVID-19 patients, MIS-C patients had lower LDH and PLT counts and higher ESR levels. Compared to KD patients, MIS-C patients had lower ALC and PLT, and higher CRP and ferritin levels. Severe MIS-C patients had higher levels of WBC, CRP, D-dimer and ferritin. For MIS-C, younger children had lower CRP and ferritin levels than medium-aged/older children. Measurement of inflammatory markers might assist clinicians in accurate evaluation and diagnosis of MIS-C and the associated disorders.

INTRODUCTION: Coronavirus disease-2019 (COVID-19) is a systemic infection which has a signicant impact on the hematopoietic system and hemostasis. Denitive diagnosis requires a laboratory conrmation test with presence of specic clinical characteristics. Patients critically ill with COVID-19 presents with hyper inammation, and the associated biomarkers may be benecial for risk stratication. During the disease course, Eosinophil count and CRP may help to effectively differentiate the suspected COVID-19 patients from others attending the fever clinic with u like symptoms. Ferritin is a key mediator of immune dysregulation and act as a crucial factor inuencing the severity of COVID-19. RESULT: 19 patients in the COVID-19 group (73%) and 4 patients in the COVID-19 negative group (16.6%) had eosinopenia. Eosinopenia and elevated C-reactive protein present with a positive predictive value at 70.7%. 14 patients with severe COVID-19 revealed elevated levels of ferritin as compared with patients having non-severe disease CONCLUSION:The combination of eosinopenia and elevated CRPcan effectively distinguish suspected COVID-19 patients from other patients attending the u clinic with COVID-19 like initial symptoms. An elevated serum CRP and ferritin were associated with poor outcome and critical phase of disease. Our study is helpful in classifying patients at the time of presentation with disease that requires hospitalization and initial therapy. The utmost importance of our study reects about early isolation of cases. AIM and Objective: Ÿ To study the role of Eosinophil count in risk stratication of patients presenting in u clinic. Ÿ To correlate the severity of disease with levels of eosinopenia, elevated CRPand Serum Ferritin.

Background and Aims Increasing evidence suggests that elevated serum levels of C-reactive protein (CRP) are associated with poor survival in many malignant tumors. However, the prognostic value of CRP in advanced gastric cancer (AGC) remains uncertain. This study was undertaken to evaluate the significance of serum CRP as a biomarker of long-term survival in patients with AGC. Methods The serum CRP levels of AGC patients were analyzed for clinicopathological significance. Data were collected retrospectively for 244 patients treated between October 1, 2006 and September 30, 2013. The prognostic effect of serum CRP levels was evaluated. Results The baseline CRP level before chemotherapy was significantly associated with overall survival. The median survival was 351 days for patients with CRP ≥10 mg/L and 370 days for patients with CRP c10 mg/L (p = 0.033). Cox analysis revealed CRP to be an independent prognostic factor for overall survival. In the 93 patients whose baseline CRP was ≥10 mg/L, a cutoff point of 22% for the CRP declining rate provided optimum sensitivity and specificity for 1-year survival based on ROC curves. A CRP declining rate >22% was found to predict longer overall survival (410 days versus 299 days; p = 0.001). Conclusions Elevated serum CRP baseline levels before chemotherapy were associated with reduced overall survival in patients with AGC. The CRP declining rate was also associated with overall survival. The CRP baseline concentration before chemotherapy and CRP declining rate after chemotherapy may be used as novel, widely available and real-time independent prognostic and predictive markers of AGC.

AbstractObjectiveTo investigate the association of antioxidant intakes from diet and supplements with elevated blood C-reactive protein (CRP) and homocysteine (Hcy) concentrations.DesignA cross-sectional study. The main exposures were vitamins C and E, carotene, flavonoid and Se intakes from diet and supplements. Elevated blood CRP and Hcy concentrations were the outcome measures.SettingThe US population and its subgroups.SubjectsWe included 8335 US adults aged ≥19 years from the National Health and Nutrition Examination Survey 1999–2002.ResultsIn this US population, the mean serum CRP concentration was 4·14 (95 % CI 3·91, 4·37) mg/l. Intakes of vitamins C and E and carotene were inversely associated with the probability of having serum CRP concentrations >3 mg/l in multivariate logistic regression models. Flavonoid and Se intakes were not associated with the odds of elevated serum CRP concentrations. The mean plasma Hcy concentration was 8·61 (95 % CI 8·48, 8·74) μmol/l. Intakes of vitamins C, E, carotenes and Se were inversely associated with the odds of plasma Hcy concentrations >13 μmol/l after adjusting for covariates. Flavonoid intake was not associated with the chance of elevated plasma Hcy concentrations.ConclusionsThese results suggest that high antioxidant intake is associated with lower blood concentrations of CRP and Hcy. These inverse associations may be among the potential mechanisms for the beneficial effect of antioxidant intake on CVD risk mediators in observational studies.

The emerging coronavirus disease (COVID-19) swept the world, affecting more than 200 countries and territories. As of August 22, 2020, the pandemic infected more than 23,329,752 including 807,054 patients who have died. Although the main clinical features of the pandemic disease are respiratory, cerebrovascular comorbidities emerged as one of the leading causes of death associated with COVID-19. Different case reports have indicated that C-reactive protein (CRP) and D-dimer (pro-inflammatory biomarkers) were elevated in COVID-19 patients, which can significantly increase the risk of ischemic stroke. Available data on cerebrovascular complications in COVID-19 patients were collected and a meta-analysis was designed and carried out to evaluate the risk of severity and mortality associated with high levels of CRP and D-dimer levels in COVID-19 patients. In addition, we aimed to describe the overall event rate of pre-existing cerebrovascular disease in COVID-19 patients. In our analysis, 5,614 cases have been studied, out of these patients 164 cases have developed cerebrovascular comorbities. Cerebrovascular comorbidity increased the risk of disease severity (odd ratio = 4.4; 95% CI: 1.48 to 12.84) and mortality (odd ratio = 7.0; 95% CI: 2.56 to 18.99). Statistical analyses showed that CRP and D-dimer serum levels were elevated by six-folds in the severe cases of COVID-19 patients. This significant increase in these two proteins levels can serve as a vital indicator for COVID-19 patients who are at increased risk of severe COVID-19 cerebrovascular complications, such as stroke.

Abstract Our study aimed to systematically analyse the risk factors of coronavirus disease 2019 (COVID-19) patients with severe disease. An electronic search in eight databases to identify studies describing severe or critically ill COVID-19 patients from 1 January 2020 to 3 April 2020. In the end, we meta-analysed 40 studies involving 5872 COVID-19 patients. The average age was higher in severe COVID-19 patients (weighted mean difference; WMD = 10.69, 95%CI 7.83–13.54). Patients with severe disease showed significantly lower platelet count (WMD = −18.63, 95%CI −30.86 to −6.40) and lymphocyte count (WMD = −0.35, 95%CI −0.41 to −0.30) but higher C-reactive protein (CRP; WMD = 42.7, 95%CI 31.12–54.28), lactate dehydrogenase (LDH; WMD = 137.4, 95%CI 105.5–169.3), white blood cell count（WBC), procalcitonin（PCT）, D-dimer, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and creatinine（Cr）. Similarly, patients who died showed significantly higher WBC, D-dimer, ALT, AST and Cr but similar platelet count and LDH as patients who survived. These results indicate that older age, low platelet count, lymphopenia, elevated levels of LDH, ALT, AST, PCT, Cr and D-dimer are associated with severity of COVID-19 and thus could be used as early identification or even prediction of disease progression.
