Abstract
Thrombomodulin (TM) is a type-I transmembrane protein that is mainly expressed on endothelial cells and plays important roles in many biological processes. Circulating TM of different forms are also present in biofluids, such as blood and urine. Soluble TM (sTM), comprised of several domains of TM, is the major circulating TM which is generated by either enzymatic or chemical cleavage of the intact protein under different conditions. Under normal conditions, sTM is present in low concentrations (<10 ng/mL) in the blood but is elevated in several pathological conditions associated with endothelial dysfunction such as cardiovascular, inflammatory, infection, and metabolic diseases. Therefore, sTM level has been examined for monitoring disease development, such as disseminated intravascular coagulation (DIC), sepsis and multiple organ dysfunction syndrome in patients with novel coronavirus disease 2019 (COVID-19) recently. In addition, microvesicles (MVs) that contain membrane TM (MV-TM) have been found to be released from activated cells which also contribute to levels of circulating TM in certain diseases. Several release mechanisms of sTM and MV-TM have been reported, including enzymatic, chemical, and TM mutation mechanisms. Measurements of sTM and MV-TM have been developed and explored as biomarkers in many diseases. In this review, we summarize all these advances in three categories as follows: (1) release mechanisms of circulating TM, (2) methods for measuring circulating TM in biological samples, and (3) correlation of circulating TM with diseases. Altogether, it provides a whole picture of recent advances on circulating TM in health and disease.

Abstract
This article discusses the complications of hematopoietic stem cell transplantion (HSCT) that affect infections in HSCT recipients, with analogies to patients with hematologic malignancies. Mucositis, with mucosal barrier disruption, is common and increases the risk of gram-positive and anaerobic bacterial, and fungal infections, and can evolve to typhlitis. Engraftment syndrome; graft-versus-host disease, hepatic sinusoidal obstruction syndrome; and posterior reversible encephalopathy syndrome can affect the infectious potential either directly from organ dysfunction or indirectly from specific treatment. Pulmonary infections can predispose to life threatening complications including diffuse alveolar hemorrhage, idiopathic pulmonary syndrome, bronchiolitis obliterans syndrome, and bronchiolitis obliterans with organizing pneumonia.

Abstract
Innate immunity consists of several kinds of pathogen recognition receptors (PRRs), which participate in the recognition of pathogens and consequently activation of innate immune system against pathogens. Recently, several investigations reported that PRRs may also play key roles in the induction/stimulation of immune system related complications in microbial infections. Hepatitis B virus (HBV), as the main cause of viral hepatitis in human, can induce several clinical forms of hepatitis B and also might be associated with hepatic complications such as cirrhosis and hepatocellular carcinoma (HCC). Based on the important roles of PRRs in the eradication of microbial infections including viral infections and their related complications, it appears that the molecules may be a main part of immune responses against viral infections including HBV and participate in the HBV related complications. Thus, this review article has brought together information regarding the roles of PRRs in immunity against HBV and its complications.

Abstract
Thrombomodulin (TM) is a membrane glycoprotein expressed on endothelial cells, which plays a major role in the protein C anticoagulation pathway. In people with inflammation, TM expression can be down-regulated on endothelial cells and a soluble form released into circulation, resulting in increased risk of thrombosis and disseminated intravascular coagulation. TM is present in dogs; however, there has been minimal investigation of its expression in canine tissues, and the effects of inflammation on TM expression in canine tissues have not been investigated. The objective of this study was to evaluate endothelial TM expression in tissues from dogs with systemic inflammatory diseases. A retrospective evaluation of tissue samples of lung, spleen, and liver from dogs with and without systemic inflammatory diseases was performed using immunohistochemistry (IHC) and a modified manual IHC scoring system. TM expression was significantly reduced in all examined tissues in dogs diagnosed with septic peritonitis or acute pancreatitis.

Abstract
Sinusoidal obstruction syndrome (SOS), previously called veno-occlusive disease (VOD) can be a difficult problem after hematopoietic cell transplantation (HCT). The overall incidence has changed since the early days of allogeneic HCT. Prophylaxis and treatment remain important components of supportive care. As the indication and the comorbidities for HCT continue to change, especially with older and more infirm patients, SOS remains an important area for clinicians. I discuss how SOS could be addressed, from prophylaxis to diagnosis and potential therapy.

Abstract
Viral infections are associated with coagulation disorders. All aspects of the coagulation cascade, primary hemostasis, coagulation, and fibrinolysis, can be affected. As a consequence, thrombosis and disseminated intravascular coagulation, hemorrhage, or both, may occur. Investigation of coagulation disorders as a consequence of different viral infections have not been performed uniformly. Common pathways are therefore not fully elucidated. In many severe viral infections there is no treatment other than supportive measures. A better understanding of the pathophysiology behind the association of viral infections and coagulation disorders is crucial for developing therapeutic strategies. This is of special importance in case of severe complications, such as those seen in hemorrhagic viral infections, the incidence of which is increasing worldwide. To date, only a few promising targets have been discovered, meaning the implementation in a clinical context is still hampered. This review discusses non‐hemorrhagic and hemorrhagic viruses for which sufficient data on the association with hemostasis and related clinical features is available. This will enable clinicians to interpret research data and place them into a perspective. J. Med. Virol. 84:1680–1696, 2012. © 2012 Wiley Periodicals, Inc.

Abstract
The current gold standard for the diagnosis and staging of hand-arm vibration syndrome (HAVS) is the Stockholm workshop scale, which is subjective and relies on the patient's recalling ability and honesty. Therefore, great potentials exist for diagnostic and staging errors. The purpose of this study is to determine if objective serum tests, such as levels of soluble thrombomodulin (sTM) and soluble intercellular adhesion molecule-1 (sICAM-1), may be used in the diagnosis and staging of HAVS. Twenty two nonsmokers were divided into a control group (n = 11) and a vibration group (n = 11). The control group included subjects without history of frequent vibrating tool use. The vibration group included construction workers with average vibrating tool use of 12.2 years. All were classified according to the Stockholm workshop scale (SN, sensorineural symptoms; V, vascular symptoms. SN0, no numbness; SN1, intermittent numbness; SN2, reduced sensory perception; SN3, reduced tactile discrimination; V0, no vasospasmic attacks; V1, intermittent vasospasm involving distal phalanges; V2, intermittent vasospasm extending to middle phalanges; V3, intermittent vasospasm extending to proximal phalanges; V4, skin atrophy/necrosis). All control subjects were SN0 V0. Seven out of 11 vibration subjects were SN1 V1, and 4 out of 11 were SN1 V2. A 10-cm(3) sample of venous blood was collected from each subject. The sTM and sICAM-1 levels were determined by enzyme-linked immunosorbent assay. The mean plasma sTM levels were as follows: control group = 2.93 +/- 0.47 ng/ml, and vibration group = 3.61 +/- 0.24 ng/ml. The mean plasma sICAM-1 levels were as follows: control group = 218.8 +/- 54.1 ng/ml, and vibration group = 300.3 +/- 53.2 ng/ml. The sTM and sICAM-1 differences between control and vibration groups were statistically significant (p < 0.0002 and p < 0.001, respectively). When reference ranges provided by Hemostasis Reference Lab were used as cut-off values, all sTM and sICAM-1 levels were within range, except three vibration individuals (27%) who had sICAM-1 levels greater than the reference range. This was not statistically significant (p = 0.08). When subjects were compared based on the Stockholm workshop scale, mean plasma sTM levels were SN0 V0 group = 2.93 +/- 0.47 ng/ml, SN1 V1 group = 3.59 +/- 0.25 ng/ml, and SN1 V2 group = 3.65 +/- 0.27 ng/ml, and mean plasma sICAM-1 levels were SN0 V0 = 219 +/- 54.1 ng/ml, SN1 V1 = 275 +/- 33.5 ng/ml, and SN1 V2 = 345 +/- 54.6 ng/ml. The difference in sTM level among the three groups was statistically significant (p < 0.001). The difference in sICAM-1 level among the three groups was also statistically significant (p < 0.002). The sTM and sICAM-1 levels are statistically higher in subjects with HAVS, with levels proportional to the disease severity. However, large population studies are needed to determine the "real-life" standard reference ranges for sTM and sICAM-1.

Abstract
Patients receiving maintenance hemodialysis (HD) present with hemostatic abnormalities, which may be aggravated by comorbid conditions, especially liver disease. The factors that influence plasma levels of thrombomodulin (TM), an initiator of the anticoagulant protein C pathway, and those of tissue factor (TF), which triggers the extrinsic coagulation pathway, were assessed. In 63 HD patients, TM and TF levels were higher than those in healthy controls. In bivariate analysis, TF positively correlated with TM, and both were directly associated with the presence of viral hepatitis B or C marker, serum liver enzymes, use of erythropoietin therapy, hemoglobin levels, and duration of HD therapy, and inversely correlated with body mass index. TF was also positively associated with plasma von Willebrand factor (vWF) antigen, and inversely associated with activated partial thromboplastin time. In multivariate analysis, increased vWF, alanine aminotransferase, and use of erythropoietin independently predicted both TF and TM levels. HD patients with vWF and ALT levels lower than middle, and not treated with erythropoietin had normal TF but increased TM concentrations compared with levels in healthy controls. Increased plasma levels of TM and TF in patients on maintenance HD are surrogates of vascular endothelial injury. Liver disease and use of erythropoietin treatment are also important determinants of these markers, and should be considered in further studies.

Abstract
BACKGROUND The level of soluble thrombomodulin (sTM), a traditional marker of endothelial injury, is also dependent on renal excretory function. We studied serum sTM in chronic haemodialysis (HD) patients to determine which factors are predictive of its levels in this population. METHODS AND RESULTS sTM levels of 10.7 (5.72-30.7) ng/ml in 100 HD patients were higher than in 30 controls (P<0.0001). In a bivariate regression analysis, immunoreactive sTM was positively associated with the presence of hepatitis B virus surface antigen and/or anti-hepatitis C virus antibodies measured by third generation ELISAs (P<0.0001), and was related to certain markers of liver injury and biosynthetic dysfunction. sTM was also directly associated with time on dialysis (P=0.001), or use of unfractionated heparin (UFH) (vs enoxaparin) (P=0.0007), erythropoietin (P=0.008), ACE-inhibitors (P=0.034), acetate-buffered dialysate (vs bicarbonate) (P=0.040), pre-dialysis systolic (P=0.012), and diastolic blood pressure (P=0.043). It was negatively associated with lipoprotein(a) (P=0.029). sTM was not related to age, sex, smoking, cause of renal failure, prevalence of cardiovascular disease, amount of HD delivered, preserved residual renal function, ferritin, C-reactive protein, and other vasoactive medications used. In a multivariable analysis, a positive hepatitis marker (P=0.0002), the use of UFH (P=0.030) and erythropoietin (P=0.019), and raised pre-dialysis blood pressure (P=0.024) were positive independent predictors of high sTM level. CONCLUSION These data indicate that, in addition to endothelial activation, elevated sTM levels in HD patients may be related to viral infection and/or liver dysfunction, and influenced by modifiable factors such as increased blood pressure, and the type of heparin and erythropoietin treatment used.
