(1) Background: Respiratory insufficiency with acute respiratory distress syndrome (ARDS) and multi-organ dysfunction leads to high mortality in COVID-19 patients. In times of limited intensive care unit (ICU) resources, chest CTs became an important tool for the assessment of lung involvement and for patient triage despite uncertainties about the predictive diagnostic value. This study evaluated chest CT-based imaging parameters for their potential to predict in-hospital mortality compared to clinical scores. (2) Methods: 89 COVID-19 ICU ARDS patients requiring mechanical ventilation or continuous positive airway pressure mask ventilation were included in this single center retrospective study. AI-based lung injury assessment and measurements indicating pulmonary hypertension (PA-to-AA ratio) on admission CT, oxygenation indices, lung compliance and sequential organ failure assessment (SOFA) scores on ICU admission were assessed for their diagnostic performance to predict in-hospital mortality. (3) Results: CT severity scores and PA-to-AA ratios were not significantly associated with in-hospital mortality, whereas the SOFA score showed a significant association (p < 0.001). In ROC analysis, the SOFA score resulted in an area under the curve (AUC) for in-hospital mortality of 0.74 (95%-CI 0.63–0.85), whereas CT severity scores (0.53, 95%-CI 0.40–0.67) and PA-to-AA ratios (0.46, 95%-CI 0.34–0.58) did not yield sufficient AUCs. These results were consistent for the subgroup of more critically ill patients with moderate and severe ARDS on admission (oxygenation index <200, n = 53) with an AUC for SOFA score of 0.77 (95%-CI 0.64–0.89), compared to 0.55 (95%-CI 0.39–0.72) for CT severity scores and 0.51 (95%-CI 0.35–0.67) for PA-to-AA ratios. (4) Conclusions: Severe COVID-19 disease is not limited to lung (vessel) injury but leads to a multi-organ involvement. The findings of this study suggest that risk stratification should not solely be based on chest CT parameters but needs to include multi-organ failure assessment for COVID-19 ICU ARDS patients for optimized future patient management and resource allocation.

Введение. Синдром диссеминированного внутрисосудистого свертывания (ДВС-синдром) является частым осложнением онкогематологических заболеваний. Известно, что повреждение эндотелия сосудов играет одну из ключевых ролей в развитии коагулопатии потребления, особенно в условиях системного воспаления. Повышение концентрации синдекана-1, одного из основных протеогликанов эндотелиального гликокаликса, в плазме крови описано при различных патологических состояниях, включая острые лейкозы и ДВС-синдром. Определение его содержания у больных гемобластозами может способствовать ранней диагностике ДВС-синдрома и своевременному назначению патогенетической терапии. Цель исследования: оценить роль протеогликана синдекан-1 в диагностике ДВС-синдрома у больных гемобластозами с сепсисом. Материалы и методы. Проведен анализ гематологических и биохимических показателей периферической крови, коагулограммы, кислотно-основного состояния и сывороточного содержания синдекана-1 у 54 больных гемобластозами с признаками системного воспаления. Острый миелоидный лейкоз диагностирован у 19 (35%), острый лимфобластный лейкоз – у 10 (18%), неходжкинская лимфома – у 13 (24%), лимфома Ходжкина – у 9 (17%), множественная миелома – у 3 (6%). Концентрацию синдекана-1 сравнивали с таковой у здоровых доноров. Наличие ДВС-синдрома определяли по шкале DIC-score Международного общества по тромбозам и гемостазу (англ. International Society on Thrombosis and Hemostasis, ISTH), степень органных дисфункций – по шкале SOFA (англ. Sequential Organ Failure Assessment). Сепсис верифицировали по критериям консенсуса «Сепсис-3». Взаимосвязь уровня синдекана-1 с показателями гемограммы, коагулограммы, биохимическими параметрами и данными шкал DIC и SOFA оценивали с использованием критерия Спирмена. Диагностическую роль синдекана-1 определяли при помощи ROC-анализа. Результаты. У больных гемобластозами выявлено повышение уровня синдекана-1 по сравнению с таковым у здоровых доноров в 5,8 раз (р = 0,008). Сепсис диагностирован у 28 (52%) пациентов, явный ДВС-синдром выявлен у 14 (25%). Концентрация синдекана-1 в сыворотке крови коррелировала со значениями активированного парциального тромбопластинового времени и протромбинового времени, количеством тромбоцитов, активностью антитромбина III, показателями шкал DIC-score и SOFA. Определена диагностическая роль синдекана-1 при развитии явного ДВС-синдрома (точка отсечения – 5,48 нг/мл, чувствительность – 73%, специфичность – 90%). Заключение. Повышенный уровень синдекана-1 (более 5,48 нг/мл) может служить дополнительным критерием развития ДВС-синдрома у больных гемобластозами с сепсисом. Background. Disseminated intravascular coagulation (DIC) is a severe complication of hemoblastosis. The key role of the vascular endothelium in hemostasis regulation is well known. Its activation and damage are the most important factors of consumption coagulopathy during systemic inflammation. Increased blood level of one of the main proteoglycans of the endothelial glycocalyx – syndecan-1 has been described in various pathological conditions, including acute leukemia and DIC. Syndecan-1 level evaluation in patients with hemoblastosis can help early DIC diagnosis and improve therapy results. Objectives: to assess the role of syndecan-1 for DIC diagnosis in hemablastosis patients with sepsis. Patients/Methods. Hematological and biochemical data of peripheral blood, coagulogram, acid-base balance and serum level of syndecan-1 were analyzed in 54 patients with hemoblastosis with signs of systemic inflammation. Acute myeloid leukemia was diagnosed in 19 (35%) patients, acute lymphoblastic leukemia – in 10 (18%), non-Hodgkin’s lymphoma – in 13 (24%), Hodgkin’s lymphoma – in 9 (17%), multiple myeloma – in 3 (6%). Syndecan-1 concentration was compared with that of healthy donors. DIC was assessed by DIC-score (ISTH, International Society on Thrombosis and Hemostasis), organ dysfunction – by SOFA (Sequential Organ Failure Assessment) score. Sepsis was verified according to the third international consensus definitions for sepsis and septic shock. Relationship of syndecan-1 level with hematological, сoagulological, biochemical data and DIC or SOFA scores was assessed by Spearman rank correlation. The diagnostic value of syndecan-1 was determined by ROC-analysis. Results. Increased level of syndecan-1 in 5.8 times was revealed in patients with hemoblastosis in comparison to healthy donors (p = 0.008). Sepsis was diagnosed in 28 (52%) patients, overt DIC – in 14 (25%). Serum syndecan-1 level correlated with activated partial thromboplastin time, prothrombin time, platelet count, antithrombin III activity, DIC and SOFA scores. The diagnostic role of syndecan-1 was determined in overt DIC (cut-off – 5.48 ng/ml, sensitivity – 73%, specificity – 90%). Conclusions. Increased syndecan-1 level (more than 5.48 ng/ml) can be additional diagnostic criterion for DIC in patients with hematological malignancies and sepsis.

AbstractWe assessed the diagnostic accuracy of the age-adjusted quick Sequential Organ Failure Assessment score (qSOFA) for predicting mortality and disease severity in pediatric patients with suspected or confirmed infection. We conducted a systematic search of PubMed, EMBASE, the Cochrane Library, and Web of Science. Eleven studies with a total of 172,569 patients were included in the meta-analysis. The pooled sensitivity, specificity, and diagnostic odds ratio of the age-adjusted qSOFA for predicting mortality and disease severity were 0.69 (95% confidence interval [CI] 0.53–0.81), 0.71 (95% CI 0.36–0.91), and 6.57 (95% CI 4.46–9.67), respectively. The area under the summary receiver-operating characteristic curve was 0.733. The pooled sensitivity and specificity for predicting mortality were 0.73 (95% CI 0.66–0.79) and 0.63 (95% CI 0.21–0.92), respectively. The pooled sensitivity and specificity for predicting disease severity were 0.73 (95% CI 0.21–0.97) and 0.72 (95% CI 0.11–0.98), respectively. The performance of the age-adjusted qSOFA for predicting mortality and disease severity was better in emergency department patients than in intensive care unit patients. The age-adjusted qSOFA has moderate predictive power and can help in rapidly identifying at-risk children, but its utility may be limited by its insufficient sensitivity.

Abstract ObjectiveTo examine the prognostic performance of combining the biomarker c-reactive protein (CRP) with the quick sequential organ failure assessment (qSOFA) bedside tool on mortality prediction in adult inpatients.MethodsWe searched PubMed, MEDLINE, EMBASE, Scopus, Web of Science, Science Direct, CINAHL, Open Grey, Grey Literature Report, and the Clinical Trials registry. Title, abstract, and full text screening were performed by two independent reviewers using pre-determined eligibility criteria. The eligibility criteria were (i) original research, (ii) adult populations, (iii) a comparison between qSOFA and qSOFA combined with CRP, and (iv) set in a hospital environment. The same two reviewers independently extracted data into a pre-designed form and performed a risk of bias assessment using the Quality Assessment tool for Diagnostic Accuracy Studies version 2 (QUADAS-2). Disagreements were settled through discussion and a third reviewer was consulted if necessary. Our primary outcome is mortality.ResultsThree retrospective studies with a total of 1521 patients were included in the review. Adding CRP to qSOFA improved the Area Under the Receiver Operating Characteristic Curve (AUROC) value in all three studies by 3-10%. In the two studies with available data, the addition of CRP improved the sensitivity of qSOFA for mortality risk stratification by 43% and 71%, while decreasing the specificity by 12% and 7% respectively. The cut-off values of CRP ranged from 60 to 128.8mg/L across the three studies. A meta-analysis was not performed due to the heterogeneity across studies and the small sample size.ConclusionsThis comprehensive review provides initial evidence that combining CRP with qSOFA could improve the prognostic performance of qSOFA alone in identifying patients at risk of dying in hospital. The combined tool demonstrates potential to improve patient outcomes, especially in low resource settings. The review also reveals research gaps in this area.RegistrationPROSPERO registration No. CRD42020190973
