The Sepsis Coagulopathy Asahi Recombinant LE Thrombomodulin (SCARLET) trial has many defects, and thus cannot be the terminator of recombinant thrombomodulin (rTM). On the contrary, it provides sufficient evidence for further research. Based on analysis focusing on the failure of SCARLET and several previous anticoagulant studies, it is most important for new studies to grasp the following two points: (1) The enrolled cases should have sufficient disease severity and a clear standard for disseminated intravascular coagulation; (2) Heparin should not be used in combination with the investigated drugs. Multiple post-hoc analyses show that no combination of heparin will not increase the risk of thromboembolism. In fact, the combination of heparin can mask the true efficacy of the investigated drug. Due to the complexity of sepsis treatment and the limitations of clinical studies, the results of all treatment studies should be repeatedly verified, rather than be determined at one stroke. Some research conclusions contrary to disease physiology, pharmacology and clinical practice may be deceptive, and should be cautious rather than be simply accepted. On the other hand, the dissenting voices in the "consensus" scene are often well discussed by the authors and should be highly valued.

In the clinical settings, disseminated intravascular coagulation (DIC) and complications such as hemorrhage are commonly seen in acute promyelocytic leukemia patients, whereas thrombosis is rarely reported. We reported a case here that the patient presented with cerebral infarction as the first manifestation. During the admission, the patient encountered differentiation syndrome, pulmonary embolism, pulmonary hemorrhage, and myocardial ischemia, as well as bleeding and thrombosis complications. Hence the patient was diagnosed as DIC. After the treatment of blood transfusion instead of anticoagulation, his condition was stable and the remission was completely achieved. The treatment experience provides guides for other patients with similar complications of simultaneous bleeding and thrombosis.

disseminated intravascular coagulation (ISTH DIC) score, pediatric multiple organ dysfunction syndrome (pMODS) score and with several laboratory test findings including hemoglobin, platelet, C-reactive protein, serum albumin, total bilirubin, prothrombin time, and anti-thrombin III levels. Most of these parameters also showed significant linear correlations with the 25(OH) vitamin D level (P < 0.05). However, no statistically meaningful association was found between VDD and other clinical conditions such as the need for a mechanical ventilator, requirement for vasoactive drugs, duration of the PICU and hospital stays, or PICU mortality.CONCLUSION: There is a high prevalence of VDD in critically ill Korean children. There were significant associations between the 25(OH) vitamin D level and gastrointestinal/hepatobiliary disorders, the pMODS score and with coagulation related factors. Further large-scale studies with more specific subgroup analyses are required to more precisely assess the clinical implications of VDD in critically ill pediatric patients.]]>

Trauma-induced coagulopathy is classified into primary and secondary coagulopathy, with the former elicited by trauma and traumatic shock itself and the latter being acquired coagulopathy induced by anemia, hypothermia, acidosis, and dilution. Primary coagulopathy consists of disseminated intravascular coagulation and acute coagulopathy of trauma shock (ACOTS). The pathophysiology of ACOTS is the suppression of thrombin generation and neutralization of plasminogen activator inhibitor-1 mediated by activated protein C that leads to hypocoagulation and hyperfibrinolysis in the circulation. This review tried to clarify the validity of activated protein C hypothesis that constitutes the main pathophysiology of the ACOTS in experimental trauma models.

A 77-year-old female patient who was suspected to have had an acute hemolytic transfusion reaction was admitted to the emergency room. She received one unit of type A red blood cells in a type B patient during a total knee arthroplasty operation at another medical institution. ABO-incompatible transfusion was carried out due to an identification error between the patient and blood product. At the time of admission, acute hemolytic reaction, lactic acidosis, and disseminated intravascular coagulation were observed. She was admitted to the intensive care unit and received continuous renal replacement therapy. She maintained renal function and was moved to the general ward on the 7th day. Complications such as pulmonary edema, gastrointestinal bleeding, and ischemic colitis persisted, and the patient died on the 111th after admission. This case is the first report of death due to an ABO-incompatible transfusion in Korea. Efforts to establish a safe transfusion environment are necessary not only at individual medical institutions but also at the national level.

PURPOSE: Rhabdomyolysis is a metabolic disorder in which the content of damaged muscle cells is released into plasma. Its manifestations include asymptomatic, myalgia, gross hematuria, and complications of acute kidney injury. Because of limited data on rhabdomyolysis in children, we performed this study to determine clinical characteristics of rhabdomyolysis in children. METHODS: We retrospectively reviewed the records of patients with rhabdomyolysis who were treated at the Pusan National University Children's hospital from January 2011 to July 2016. The diagnostic criteria were serum myoglobin level of ≥80 ng/mL, exclusive of acute myocardial injury, cardiac arrest, and brain damage. RESULTS: Forty-five patients were enrolled; mean age, 116±68 months. Of these, 35 were boys and 10 were girls. Twenty-six patients experienced myalgia and 12 patients showed gross hematuria. Among these, seven patients initially had both myalgia and gross hematuria. The most common causes of rhabdomyolysis were infection, physical exertion, prolonged seizures, metabolic abnormalities, and drug addiction. Acute kidney injury (AKI) was the most common complication, followed by disseminated intravascular coagulation. Thirty-seven patients improved with sufficient fluid supply but two patients underwent hemodialysis due to deterioration of kidney function. Gross hematuria, positive occult blood test, and positive urine protein were more common in patients with AKI than in those without AKI. CONCLUSIONS: In children, infection was the most common cause of rhabdomyolysis. Most patients recovered by sufficient fluid therapy. However, in severe cases, especially in patients with underlying kidney disease, hemodialysis may be necessary in the present study.

Objective: To evaluate the applicability of Chinese disseminated intravascular coagulation scoring system (CDSS) in the diagnose of DIC in patients with acute promyelocytic leukemia (APL) patients. Methods: Medical records of 220 APL patients diagnosed and receiving induction therapy in Blood Disease Hospital, CAMS & PUMC from January 2004 to February 2018 were retrospectively analyzed. Each patient was evaluated by CDSS, the International Society of Thrombosis and Haemostais (ISTH) scoring system for overt DIC and Japanese Ministry of Health and Welfare (JMHW) scoring system for overt DIC, respectively. Results: A total of 220 APL patients were enrolled in the study, with a median age of 38.5 (12-70) years, 114 male and 106 female. Among them, 173 were in the low-medium risk group, 47 high-risk group; 11 patients died during induction treatment. The positive rates of DIC diagnosed by CDSS criteria, ISHT criteria, JMHW criteria was 62.27%, 54.09%, 69.09%, respectively. The consistency rate of CDSS and ISTH in diagnosing DIC was 78.10%; the consistency rate of CDSS and JMHW was 88.32%. There was significant difference in PT, APTT, FIB, D-Dimer and FDP in DIC(+) and DIC(-) group by CDSS (all P<0.05), but patients in the DIC(+) group had lower level of D-Dimer than in the DIC(-) group [21.9(1.2-477.1) mg/L vs 26.3(0.6-488.7) mg/L, χ(2)=1.871, P=0.002] by ISTH, and there was not significant difference in APTT by JMHW [27.05(18.0-181.0) s vs 26.15(18.2-35.5) s, χ(2)=1.162, P=0.134]. In this study, both of the gender and age had no difference in the DIC (+) and DIC (-) group by CDSS. Univariate analysis showed that the level of WBC and the percent of abnormal promyelocytic cells in bone marrow when diagnosed were different in DIC (+) and DIC (-) group by CDSS (P<0.05). Multiple analysis showed the level of WBC (OR=3.525, 95% CI 1.875-6.629, P<0.001) was the only independent predictor in DIC diagnosis by CDSS. Conclusion: The sensitivity of diagnosing DIC by CDSS was higher than the ISTH; and the specificity was superior to JMHW. Using CDSS can help to make the DIC diagnosis and treatment in time for APL patients who with the coagulation abnormalities.

Objective: PLASMIC score was evaluated its value in differential diagnosis between the patients with thrombotic thrombocytopenic purpura (TTP) and those with disseminated intravascular coagulation (DIC) . Method: Twenty-four patients with TTP and 41 cases with DIC were retrospectively analyzed in this study. The platelet count, average red blood cell volume, indirect bilirubin, creatinine and prothrombin time international normalised ratio were collected, and then PLASMIC scores were calculated. Results: According to the risk classification of PLASMIC score, three (12.5%) TTP patients had moderate risk, and the rest 21 (87.5%) cases had high risk. In DIC patients, 92.7% cases were in low risk group, 4.9% at moderate risk, and only one case had high risk. Of these 65 patients, the sensitivity and the specificity to TTP of the high risk of the scoring system were 87.5% and 97.6%, respectively. Conclusion: The patients with high risk of PLASMIC score correlated well with clinical TTP diagnosis. The scoring system showed to be an excellent diagnostic model to distinguish TTP patients from those with DIC.

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide. The finding that cellular microparticles (MPs) generated by injured cells profoundly impact on pathological courses of TBI has paved the way for new diagnostic and therapeutic strategies. MPs are subcellular fragments or organelles that serve as carriers of lipids, adhesive receptors, cytokines, nucleic acids, and tissue-degrading enzymes that are unique to the parental cells. Their sub-micron sizes allow MPs to travel to areas that parental cells are unable to reach to exercise diverse biological functions. In this review, we summarize recent developments in identifying a casual role of MPs in the pathologies of TBI and suggest that MPs serve as a new class of therapeutic targets for the prevention and treatment of TBI and associated systemic complications.
