The results of thromboelastography and standard coagulogram were analyzed in 35 patients aged from 18 to 86 who were treated in the resuscitation and intensive care unit. The majority of patients (34%) were hospitalized in the department with multisystem and concomitant injuries. The remaining patients were taken to the medical institution with different diagnoses (urolithiasis, liver cirrhosis, pancreatic lesion of various types, poisoning, peptic ulcer, sepsis). The data of coagulogram and thromboelastography at different stages of treatment were compared. In patients with the development of traumatic shock, the coagulogram parameters were changed to varying degrees depending on the stage of shock. At the first stage of shock, only an increase in soluble fibrin-monomer complexes by almost 2 times and a slight increase in fibrinogen dynamics were noted in the analysis. In a patient with stage 3 traumatic shock, the coagulogram parameters were within the normal range, but according to thromboelastography (EXTEM and FIBTEM tests), hypocoagulation due to the platelet link was noted. Only the coagulogram was evaluated in dynamics, hypocoagulation was noted in the indicators of internal and external hemostasis pathways: lengthening of the activated partial thromboplastin time, a decrease in the prothrombin index and an increase in the international normalized ratio, an increase in fibrinogen A and soluble fibrin-monomer complexes. In the group of male patients with closed craniocerebral trauma, an increase in soluble fibrin-monomer complexes in the coagulogram was always combined with changes in the FIBTEM test during thromboelastography. In most patients, no changes in the classical coagulogram tests immediately after the injury are noted. At this, thromboelastography makes it possible to make up for this deficiency at an earlier time, which indicates a high sensitivity of the method.

SummaryIn the present paper described is a simple test for detecting soluble fibrin monomer complexes (SFMC) in blood. The test consists in mixing 1% protamine sulphate with diluted oxalated plasma or serum and reading the optical density at 6190 Å. In experiments with dog plasma, enriched with soluble fibrin complexes, it was shown that OD read in PS test is proportional to the amount of fibrin recovered from the precipitate. It was found that SFMC level in plasma increases in rabbits infused intravenously with thrombin and decreases after injection of plasmin with streptokinase. In both cases PS precipitable protein in serum is elevated indicating enhanced fibrinolysis. In healthy human subjects the mean value of OD readings in plasma and sera were found to be 0.30 and 0.11, while in patients with coronary thrombosis they are 0.64 and 0.05 respectively. The origin of SFMC in circulation under physiological and pathological conditions is discussed.

SummaryVarious assays have been developed for quantitation of soluble fibrin or fibrin monomer in clinical plasma samples, since this parameter directly reflects in vivo thrombin action on fibrinogen. Using plasma samples from healthy blood donors, patients with cerebral ischemic insult, patients with septicemia, and patients with venous thrombosis, we compared two immunologic tests using monoclonal antibodies against fibrin-specific neo-epitopes, and two functional tests based on the cofactor activity of soluble fibrin complexes in tPA-induced plasminogen activation. Test A (Enzymun®-Test FM) showed the best discriminating power among normal range and pathological samples. Test B (Fibrinostika® soluble fibrin) clearly separated normal range from pathological samples, but failed to discriminate among samples from patients with low grade coagulation activation in septicemia, and massive activation in venous thrombosis. Functional test C (Fibrin monomer test Behring) displayed good discriminating power between normal and pathological range samples, and correlated with test A (r = 0.61), whereas assay D (Coa-Set® Fibrin monomer) showed little discriminating power at values below 10 μg/ml and little correlation with other assays. Standardization of assays will require further characterization of analytes detected.

AbstractBackgroundComprehensive information has been published on laboratory tests which may predict worse outcome in Asian populations with coronavirus disease 2019 (COVID-19). The aim of this study is to describe laboratory findings in a group of Italian COVID-19 patients in the area of Valcamonica, and correlate abnormalities with disease severity.MethodsThe final study population consisted of 144 patients diagnosed with COVID-19 (70 who died during hospital stay and 74 who survived and could be discharged) between March 1 and 30, 2020, in Valcamonica Hospital. Demographical, clinical and laboratory data were collected upon hospital admission and were then correlated with outcome (i.e. in-hospital death vs. discharge).ResultsCompared to patients who could be finally discharged, those who died during hospital stay displayed significantly higher values of serum glucose, aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH), urea, creatinine, high-sensitivity cardiac troponin I (hscTnI), prothrombin time/international normalized ratio (PT/INR), activated partial thromboplastin time (APTT), D-dimer, C reactive protein (CRP), ferritin and leukocytes (especially neutrophils), whilst values of albumin, hemoglobin and lymphocytes were significantly decreased. In multiple regression analysis, LDH, CRP, neutrophils, lymphocytes, albumin, APTT and age remained significant predictors of in-hospital death. A regression model incorporating these variables explained 80% of overall variance of in-hospital death.ConclusionsThe most important laboratory abnormalities described here in a subset of European COVID-19 patients residing in Valcamonica are highly predictive of in-hospital death and may be useful for guiding risk assessment and clinical decision-making.

ABSTRACT Postoperative or posttraumatic sepsis remains one of the leading causes of morbidity and mortality in hospital populations, especially in populations in intensive care units (ICUs). Central to the successful control of sepsis-associated infections is the ability to rapidly diagnose and treat disease. The ability to identify sepsis patients before they show any symptoms would have major benefits for the health care of ICU patients. For this study, 92 ICU patients who had undergone procedures that increased the risk of developing sepsis were recruited upon admission. Blood samples were taken daily until either a clinical diagnosis of sepsis was made or until the patient was discharged from the ICU. In addition to standard clinical and laboratory parameter testing, the levels of expression of interleukin-1β (IL-1β), IL-6, IL-8, and IL-10, tumor necrosis factor-α, FasL, and CCL2 mRNA were also measured by real-time reverse transcriptase PCR. The results of the analysis of the data using a nonlinear technique (neural network analysis) demonstrated discernible differences prior to the onset of overt sepsis. Neural networks using cytokine and chemokine data were able to correctly predict patient outcomes in an average of 83.09% of patient cases between 4 and 1 days before clinical diagnosis with high sensitivity and selectivity (91.43% and 80.20%, respectively). The neural network also had a predictive accuracy of 94.55% when data from 22 healthy volunteers was analyzed in conjunction with the ICU patient data. Our observations from this pilot study indicate that it may be possible to predict the onset of sepsis in a mixed patient population by using a panel of just seven biomarkers.

ABSTRACT Objective: The aim of this study was to compare the incidence of different criteria of maternal near miss in women admitted to an obstetric intensive care unit and their sensitivity and specificity in identifying cases that have evolved to morbidity. Method: A cross-sectional analytical epidemiological study was conducted with women admitted to the intensive care unit of the Maternity School Assis Chateaubriand in Ceará, Brazil. The Chi-square test and odds ratio were used. Results: 560 records were analyzed. The incidence of maternal near miss ranged from 20.7 in the Waterstone criteria to 12.4 in the Geller criteria. The maternal near-miss mortality ratio varied from 4.6:1 to 7.1:1, showing better index in the Waterstone criteria, which encompasses a greater spectrum of severity. The Geller and Mantel criteria, however, presented high sensitivity and low specificity. Except for the Waterstone criteria, there was an association between the three other criteria and maternal death. Conclusion: The high specificity of Geller and Mantel criteria in identifying maternal near miss considering the World Health Organization criteria as a gold standard and a lack of association between the criteria of Waterstone with maternal death.

Aim    To compare features of the disease course and the effectiveness of nonsteroidal anti-inflammatory drug (NSAID) treatment of postpericardiotomy syndrome (PPS) in patients after coronary bypass (CB) surgery who were treated with antiplatelet drugs and in patients after surgical correction of heart valve disease (CHVD) who received the anticoagulant warfarin for prevention of thrombotic complications. Material and methods    This study included 89 patients of whom 53 patients had underwent CB and 36 patients had underwent CHVD. At 15 [13; 15] days after surgery, the severity of inflammatory response, the state of coagulation hemostasis, and hematocrit were studied. At 5 days after the first test, blood count and measurement of C-reactive protein were repeated. Echocardiography was used to determine the presence and volume of pleural effusion. For prevention of thrombotic complications, antiplatelet drugs were administered after CB and warfarin was administered after CHVD. PPS was detected in 35 (66 %) patients after CB and 18 (50 %) patients after CHVD. The ibuprofen treatment (600 mg twice a day) was administered to all patients with PPS. If positive changes in inflammatory markers were absent during the NSAID treatment, ibuprofen was replaced with prednisolone 0.5 mg/kg body weight with subsequent laboratory and instrumental monitoring. Results    Patients after CHVD treated with warfarin had higher values of international normalized ratio (INR) and activated partial thromboplastin time (aPPT) and lower values of prothrombin index (PTI), fibrinogen (p<0.001 for all), hemoglobin (p=0.0016), and hematocrit (p=0,0032) than patients after CB treated with antiplatelet drugs. 21 (40 %) patients with PPS required changing the anti-inflammatory therapy from ibuprofen to prednisolone. These patients displayed hypocoagulation, which was evident as reduced PTI (p=0.0023) and fibrinogen (p=0.0209), increased INR (p=0.0291) and aPPT (p=0.0416), and a higher incidence of pericardial effusion (p=0.0080). The insufficient effectivity of NSAIDs that required administration of prednisolone was more frequently observed in patients after CHVD (61 % vs. 29 %, р=0.037).Conclusion    Hypocoagulation observed in patients after CHVD due to the anticoagulant treatment with warfarin was associated with more severe course of PPS and lower effectiveness of the NSAID treatment compared to patients after CB. This results in more frequent replacement of NSAIDs with glucocorticoids in the treatment of patients after CHVD.
