Abstract
BACKGROUND Disseminated intravascular coagulation (DIC) syndrome is a highly lethal condition characterized by the complication of multiple organ damage. Although the effects of combined antithrombin (AT) and recombinant thrombomodulin (rTM) on DIC syndrome have previously been examined, the results are inconsistent and inconclusive. Therefore, we conducted a systematic review on the combined administration of AT and rTM for the treatment of septic DIC to investigate the superiority of the combination therapy over either AT or rTM monotherapy using a random-effects analysis model. METHOD We searched electronic databases, including Medline, Cochrane Central Register of Controlled Trials, Scopus, and Igaku-Chuo Zasshi (ICHU-SHI) Japanese Central Review of Medicine Web from inception to January 2022. Studies assessing the efficacy of combined AT and rTM were included. The primary outcome was all-cause mortality, and the secondary outcome was occurrence of serious bleeding complications compared to monotherapy. We presented the pooled odds ratio (OR) or hazard ratio (HR) with 95% confidence intervals (CI) depending on reporting results in each primary study. RESULTS We analyzed seven enrolled clinical trials, all of which were observational studies. Combination therapy had a non-significant favorable association with lower 28-day mortality compared to monotherapy (HR 0.67 [0.43-1.05], OR 0.73 [0.45-1.18]). The I(2) values were 60% and 72%, respectively, suggesting high heterogeneity. As a secondary outcome, bleeding complications were similar between the two groups (pooled OR 1.11 [0.55-2.23], I(2) value 55%). CONCLUSIONS Although the findings in this analysis could not confirm a statistically significant effect of AT and rTM combination therapy for septic DIC, it showed a promising effect in terms of improving mortality. The incidence of bleeding was low and clinically feasible. Further research is warranted to draw more conclusive results. TRIAL REGISTRATION This study was registered in the University Hospital Medical Information Network (UMIN) Clinical Trials Registry (UMIN ID 000049820).

Abstract
BACKGROUND Recombinant human soluble thrombomodulin (rhTM) is used to treat sepsis-induced disseminated intravascular coagulation (DIC). However, no consistent clinical guidelines exist regarding the administration of rhTM in patients with sepsis-induced DIC. Therefore, we conducted this meta-analysis to evaluate the efficacy and safety of rhTM therapy in patients with sepsis-induced DIC. METHODS EMBASE, PubMed, Scopus, Ichushi, and CINAHL databases were used to search for relevant articles that met the inclusion criteria of patients with sepsis-induced DIC treated with and without rhTM through November 2022. Mortality, DIC resolution, and incidence of bleeding complications were evaluated. DIC resolution was defined as the recovery from DIC after the start of DIC treatment. RESULTS Of the 1697 citations identified for screening, 17 studies involving 2296 patients were included. Administering rhTM significantly reduced mortality (odds ratio (OR) 0.54, 95 % confidence interval (CI) 0.42-0.71) and improved DIC resolution (OR 2.88, 95 % CI 1.83-4.52). There were no significant differences in the incidence of bleeding complications between the rhTM and control groups (OR 0.92, 95 % CI 0.66-1.28). CONCLUSIONS Our meta-analysis revealed that rhTM could reduce mortality and improve DIC resolution without increasing the risk of bleeding in patients with sepsis-induced DIC. Our findings suggest that rhTM is a relatively effective and safe anticoagulant for the treatment of sepsis-induced DIC. SUMMARY Recombinant human soluble thrombomodulin reduced mortality without increasing the bleeding risk in the treatment of sepsis-induced disseminated intravascular coagulation.

Chen, D., Hou, Y., Wei, C., Cai, X.
International Journal of Clinical Practice. 2022;2022:2124019
Abstract
Previous studies suggest that sepsis remains a common critical illness with a global incidence of 31.5 million. The aim of this study was to evaluate the comparative therapeutic value of recombinant human thrombopoietin (rhTPO) in treating sepsis patients with thrombocytopenia. We conducted a comprehensive electronic search of PubMed, EMBASE, the Cochrane Library, and CNKI from its inception through December 31, 2021. Thirteen randomized controlled trials (RCTs) involving 963 patients were included. Network meta-analyses showed that rhTPO 300 U/kg/day and rhTPO 15000 U/day significantly increased the platelet (PLT) levels on the 7(th) day and decreased the requirement of transfusion of red blood cells (RBCs), plasma, and PLT compared with IVIG and NAT. SUCRA showed that rhTPO 300 U/kg/day ranked first in terms of 28-day mortality (85.5%) and transfusion, including RBC (88.7%), plasma (89.6%), and PLT (95.2%), while rhTPO 15000 U/day ranked first for the length of the intensive care unit (ICU) stay (95.9%) and PLT level at day 7 (91.6%). rhTPO 300 U/kg/day may be the optimal dose to reduce 28-day mortality and transfusion requirements. However, rhTPO 15000 U/day may be the optimal dose for shortening the ICU stay and increasing the PLT level on the 7th day. However, additional studies to further validate our findings are needed.

Abstract
BACKGROUND The effect of early vasopressin initiation on clinical outcomes in patients with septic shock is uncertain. A systematic review and meta-analysis was performed to evaluate the impact of early start of vasopressin support within 6 h after the diagnosis on clinical outcomes in septic shock patients. METHODS We searched the PubMed, Cochrane, and Embase databases for randomized controlled trials (RCTs) and cohort studies from inception to the 1st of February 2021. We included studies involving adult patients (> 16 years)with septic shock. All authors reported our primary outcome of short-term mortality and in the experimental group patients in the studies receiving vasopressin infusion within 6 h after diagnosis of septic shock and in the control group patients in the studies receiving no vasopressin infusion or vasopressin infusion 6 h after diagnosis of septic shock, clearly comparing with clinically relevant secondary outcomes(use of renal replacement therapy(RRT),new onset arrhythmias, ICU length of stay and length of hospitalization). Results were expressed as odds ratio (OR) and mean difference (MD) with accompanying 95% confidence interval (CI). RESULTS Five studies including 788 patients were included. The primary outcome of this meta-analysis showed that short-term mortality between the two groups was no difference (odds ratio [OR] = 1.09; 95% CI, 0.8 to 1.48; P = 0.6; χ2 = 0.83; I2 = 0%). Secondary outcomes demonstrated that the use of RRT was less in the experimental group than that of the control group (OR = 0.63; 95% CI, 0.44 to 0.88; P = 0.007; χ2 = 3.15; I2 = 36%).The new onset arrhythmias between the two groups was no statistically significant difference (OR = 0.59; 95% CI, 0.31 to 1.1; P = 0.10; χ2 = 4.7; I2 = 36%). There was no statistically significant difference in the ICU length of stay(mean difference = 0.16; 95% CI, - 0.91 to 1.22; P = 0.77; χ2 = 6.08; I2 = 34%) and length of hospitalization (mean difference = -2.41; 95% CI, -6.61 to 1.78; P = 0.26; χ2 = 8.57; I2 = 53%) between the two groups. CONCLUSIONS Early initiation of vasopressin in patients within 6 h of septic shock onset was not associated with decreased short-term mortality, new onset arrhythmias, shorter ICU length of stay and length of hospitalization, but can reduce the use of RRT. Further large-scale RCTs are still needed to evaluate the benefit of starting vasopressin in the early phase of septic shock.

Revista Brasileira de terapia intensiva. 2021;33(1):154-166
Abstract
Red blood cell transfusion is thought to improve cell respiration during septic shock. Nevertheless, its acute impact on oxygen transport and metabolism in this condition remains highly debatable. The objective of this study was to evaluate the impact of red blood cell transfusion on microcirculation and oxygen metabolism in patients with sepsis and septic shock. We conducted a search in the MEDLINE®, Elsevier and Scopus databases. We included studies conducted in adult humans with sepsis and septic shock. A systematic review and meta-analysis were performed using the DerSimonian and Laird random-effects model. A p value < 0.05 was considered significant. Nineteen manuscripts with 428 patients were included in the analysis. Red blood cell transfusions were associated with an increase in the pooled mean venous oxygen saturation of 3.7% (p < 0.001), a decrease in oxygen extraction ratio of -6.98 (p < 0.001) and had no significant effect on the cardiac index (0.02L/minute; p = 0,96). Similar results were obtained in studies including simultaneous measurements of venous oxygen saturation, oxygen extraction ratio, and cardiac index. Red blood cell transfusions led to a significant increase in the proportion of perfused small vessels (2.85%; p = 0.553), while tissue oxygenation parameters revealed a significant increase in the tissue hemoglobin index (1.66; p = 0.018). Individual studies reported significant improvements in tissue oxygenation and sublingual microcirculatory parameters in patients with deranged microcirculation at baseline. Red blood cell transfusions seemed to improve systemic oxygen metabolism with apparent independence from cardiac index variations. Some beneficial effects have been observed for tissue oxygenation and microcirculation parameters, particularly in patients with more severe alterations at baseline. More studies are necessary to evaluate their clinical impact and to individualize transfusion decisions.

Abstract
OBJECTIVE To investigate the effect of terlipressin on prognosis of adult septic shock patients. METHODS All randomized controlled clinical trials (RCT) of terlipressin in the treatment of adult septic shock patients from January 1980 to December 2019 were retrieved from CNKI, Wanfang, SinoMed, PubMed, Embase, Springer Link, Cochrane Library, Google Scholar, and etc. Patients in the treatment group received terlipressin while patients in the control group received norepinephrine or other vasopressors. Main outcome indicator was mortality. Secondary outcome indicators included the incidence of severe adverse events, limb peripheral ischemic events and renal complications. Literature screening, data extraction and quality evaluation were conducted by two researchers respectively. Meta-analysis was performed with RevMan 5.3 software. Funnel plot was used to analyze the publication bias. RESULTS A total of 507 related literatures were retrieved. According to the inclusion and exclusion criteria, 8 RCT studies were finally included, with a total of 811 patients. One study was considered to have a lower risk of bias, 6 studies had uncertain risk of bias, and 1 study had a higher risk of bias. The Meta-analysis showed that terlipressin did not significantly improve the mortality of septic shock patients compared with the control group [odds ratio (OR) = 0.89, 95% confidence interval (95%CI) was 0.67-1.19, P = 0.45]; increased the incidence of severe adverse events (OR = 2.98, 95%CI was 1.99-4.45, P < 0.000 01); there was a tendency to increase the incidence of limb peripheral ischemic events, but without statistical difference (OR = 10.81, 95%CI was 0.88-133.19, P = 0.06); and reduced the incidence of renal complications (OR = 0.30, 95%CI was 0.09-0.96, P = 0.04). Funnel plot analysis indicated that there might be publication bias in a study on case fatality and incidence of serious adverse events in the included literature. No significant publication bias was found in studies on the incidence of limb peripheral ischemic events and the incidence of kidney-related complications. CONCLUSIONS The available evidence suggests that terlipressin could not significantly improve mortality in adult's septic shock patients, but it may reduce the incidence of renal complications. A tendency to increase the incidence of limb peripheral ischemic events in the terlipressin-treated group needs to be emphasized.

Journal of critical care. 2020;61:5-13
Abstract
BACKGROUND Thromboelastometry/elastography (ROTEM/TEG) showed promising results for diagnosis of sepsis-induced coagulopathy, but their association with the outcome is unclear. Our aim was to assess any difference in ROTEM/TEG measurements between septic survivors and non-survivors. METHODS Pubmed, Web of Science, Embase and Cochrane Library databases were investigated. The research aimed to include any randomized or observational study: i) on septic adult patients admitted to Intensive Care Unit (ICU) or Emergency Department (ED); ii) including ROTEM/TEG; iii) assessing mortality. RESULTS Seven prospective and four retrospective observational studies (952 patients) were included. According to the INTEM/kaolin-assay, clotting time (CT)/R (standardized mean difference(SMD) -0.29, 95% CI -0.49 to -0.09, p = 0.004) and clot formation time (CFT)/K (SMD -0.42, 95% CI -0.78 to -0.06, p = 0.02) were shorter in survivors. According to the EXTEM-assay, CT was shorter (MD -11.66 s, 95% CI -22.59 to -0.73, p = 0.04), while MCF was higher (MD 3.49 mm, 95% CI 0.43 to 6.55, p = 0.03) in survivors. A hypocoagulable profile was more frequent in non-survivors (OR 0.31, 95%CI 0.18 to 0.55, p < 0.0001). Overall, the risk of bias of the included studies was moderate and the quality of evidence low. CONCLUSIONS Hypocoagulability and lower MCF in EXTEM may be associated with higher mortality in sepsis.

Front Pharmacol. 2020;11:940
Abstract
BACKGROUND The efficacy and safety of the administration of recombinant human thrombopoietin (rhTPO) in sepsis patients with thrombocytopenia were still inconclusive. OBJECTIVES To investigate whether rhTPO is a benefit for sepsis patients with thrombocytopenia. METHODS PubMed, Cochrane library, Embase, China National Knowledge Infrastructure, and Wanfang Database were electronically searched to the randomized controlled trials (RCTs) from inception to March 4, 2020. The primary outcome was the level of platelet (PLT) on the 7(th) day of treatment, and secondary outcomes were 28-d mortality, the level of coagulation indicators, hepatic and renal function indicators, blood transfusion, and length of intensive care unit (ICU) stay. RESULTS Ten RCTs involving 681 patients were included. For compared with conventional antibiotic therapy, rhTPO could significantly increase platelet counts (PCs) [standardized mean difference (SMD), 2.61; 95% confidence interval (CI), 1.28-3.94; P < 0.001], decreased 28-d mortality [relative risk (RR), 0.66; 95%CI, 0.46-0.97; P=0.03], transfusion volume of blood products and length of ICU stay. Additionally, for compared with conventional antibiotic therapy combined with intravenous immunoglobulin, the pooled results shown that rhTPO also associated with an improvement of PCs on 7(th) of treatment (SMD, 0.86; 95%CI, 0.54-1.17; P < 0.001), and a reduced transfusion volume of blood products. However, there were no differences in 28-d mortality and the length of ICU stay. CONCLUSIONS Current evidence shown that rhTPO could increase PCs on 7(th) day of treatment and reduce the transfusion volume of blood products in sepsis-related thrombocytopenia during hospitalization. The conclusions are needed to be verified indeed by more multicenter RCTs due to the limitation of the included studies.

Front Pharmacol. 2020;11:563
Abstract
Background: Vasopressin is an efficient remedy for septic shock patients as its great capacity in promoting hemodynamic stabilization. The aim of current systematic review and meta-analysis is to compare the clinical efficiency of vasopressin or its analogs with sole catecholamines on patients with septic shock. Methods: A systematic search of Cochrane Library, EMBASE, and PubMed online databases was performed up to 30 Oct 2019 to identify randomized controlled trials comparing use of vasopressin or its analogs (e.g., terlipressin, selepressin) with administration of catecholamines alone. Results: We included 23 RCTs with 4,225 patients in the current study. Compared with solely use of catecholamines, administration of vasopressin or its analogs was not associated with reduced 28-day or 30-day mortality among patients with septic shock [RR=0.94 (95% CI, 0.87-1.01), P=0.08, I(2) = 0%]. The result of primary endpoint remained unchanged after conducting sensitivity analysis. Despite a significantly higher risk of digital ischemia in patients receiving vasopressin or its analogs [RR=2.65 (95% CI, 1.26-5.56), P < 0.01, I(2) = 48%], there was no statistical significance in the pooled estimate for other secondary outcomes, including total adverse events, arrhythmia, acute myocardial infarction (AMI) and cardiac arrest, acute mesenteric ischemia, ICU/hospital length of stay, and mechanical ventilation (MV) duration. Conclusions: The administration of vasopressin or its analogs was not associated with reduced 28-day or 30-day mortality among patients with septic shock, while an increased incidence of digital ischemia should be noted in patients receiving agonists for vasopressin receptors.

BMC anesthesiology. 2020;20(1):58
Abstract
BACKGROUND Catecholamines are the first-line vasopressors used in patients with septic shock. However, the search for novel drug candidates is still of great importance due to the development of adrenergic hyposensitivity accompanied by a decrease in catecholamine activity. Terlipressin (TP) is a synthetic vasopressin analogue used in the management of patients with septic shock. In the current study, we aimed to compare the effects of TP and catecholamine infusion in treating septic shock patients. METHODS A systematic review and meta-analysis was conducted by searching articles published in PUBMED, EMBASE, and the Cochrane Central Register of Controlled Trials between inception and July 2018. We only selected randomized controlled trials evaluating the use of TP and catecholamine in adult patients with septic shock. The primary outcome was overall mortality. The secondary outcomes were the ICU length of stay, haemodynamic changes, tissue perfusion, renal function, and adverse events. RESULTS A total of 9 studies with 850 participants were included in the analysis. Overall, no significant difference in mortality was observed between the TP and catecholamine groups (risk ratio(RR), 0.85 (0.70 to 1.03); P = 0.09). In patients < 60 years old, the mortality rate was lower in the TP group than in the catecholamine group (RR, 0.66 (0.50 to 0.86); P = 0.002). There was no significant difference in the ICU length of stay (mean difference, MD), - 0.28 days; 95% confidence interval (CI), - 1.25 to 0.69; P = 0.58). Additionally, TP improved renal function. The creatinine level was decreased in patients who received TP therapy compared to catecholamine-treated participants (standard mean difference, SMD), - 0.65; 95% CI, - 1.09 to - 0.22; P = 0.003). No significant difference was found regarding the total adverse events (Odds Ratio(OR), 1.48(0.51 to 4.24); P = 0.47), whereas peripheral ischaemia was more common in the TP group (OR, 8.65(1.48 to 50.59); P = 0.02). CONCLUSION The use of TP was associated with reduced mortality in septic shock patients less than 60 years old. TP may also improve renal function and cause more peripheral ischaemia.
