Efficacy and Safety of Recombinant Human Thrombopoietin on Sepsis Patients With Thrombocytopenia: A Systematic Review and Meta-Analysis.

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 7th 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 7th 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 7th 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.

Project description:BackgroundSepsis is still a major health problem that causes high mortality in all populations. Organ dysfunction including sepsis-associated thrombocytopenia is prevalent among sepsis patients, resulting in increasing mortality rates. Considering the clinical role of platelets, thrombocytopenia in sepsis has led to a large spend in research activity and clinical trials in this area, yet there is no consensus upon which treatment should be administered. As a result, platelet transfusion is often indicated to resolve low platelet counts, leading to an increasing risk of the multiple risks transfusion brings, such as infectious or immune system complications. Given the role of thrombopoietin in stimulating proliferation and differentiation of megakaryocytes, our previous study investigated the potential benefits of recombinant human thrombopoietin in severe sepsis patients with thrombocytopenia. However, there are several limitations in the study, which may have led to bias in our conclusion. Thus, we are conducting this study in order to evaluate the safety and efficacy of recombinant human thrombopoietin in a large, varied population.Methods/designThe study is designed as a randomized, open-label, placebo-controlled, multi-center study in tertiary academic centers for evaluating the safety and efficacy of recombinant human thrombopoietin over placebo. An established total of 708 patients with sepsis and thrombocytopenia will undergo prospective random assignment to recombinant human thrombopoietin or placebo (a 1:1 ratio). The primary endpoint is 7-day all-cause mortality and 28-day all-cause mortality.DiscussionTo our knowledge, this is the first study to evaluate the safety and efficacy of recombinant human thrombopoietin among severe sepsis patients with thrombocytopenia in a varied population. With our study, the level of evidence for the treatment of these patients will be significantly raised.Trial registrationClinicalTrials.gov: NCT02094248 . Registration date: 23 March 2014.

Project description:Thrombopoietin receptor agonists (TPO-RAs) play a crucial role in stimulating thrombopoiesis. However, conventional meta-analyses have shown inconsistent results regarding the efficacy of thrombopoietin receptor agonists versus placebo. Therefore, we performed a network meta-analysis to assess the effects of five TPO-RAs via indirect comparison. For this network meta-analysis, we considered randomized trials that included any of the following interventions: avatrombopag, lusutrombopag, eltrombopag, romiplostim, recombinant human thrombopoietin (rhTPO). We searched the Medline, PubMed, Embase, the Cochrane Library, and Web of Science databases for randomized controlled clinical trials from inception to January 31, 2021. We use randomized controlled clinical trials of TPO-RAs for treatment of immune thrombocytopenia in adults. The primary outcome was the number of patients achieving platelet response which was defined as the achievement of a platelet count of more than 30 or 50 cells × 109/L in the absence of rescue therapy, and the secondary outcome was the therapy-related serious adverse events and incidence of bleeding episodes. To obtain the estimates of efficacy and safety outcomes, we performed a random-effects network meta-analysis. These estimates were presented as odds ratios with 95% confidence intervals. We use surface under the cumulative ranking probabilities to rank the comparative effects and safety of all drugs against the placebo. In total, 2,207 patients were analyzed in 20 clinical trials. All preparations improved the point estimates of platelet response when compared with the placebo. Avatrombopag and lusutrombopag had the best platelet response compared to the placebo, the former had a non-significant advantage compared to the latter [odds ratio (OR) = 1.91 (95% confidence interval: 0.52, 7.05)]. The treatments were better than eltrombopag, romiplostim, rituximab, and rhTPO + rituximab, with corresponding ORs of 3.10 (1.01, 9.51), 9.96 (2.29, 43.29), 33.09 (8.76, 125.02), and 21.31 (3.78, 119.98) for avatrombopag and 1.62 (0.63, 4.17), 5.21 (1.54, 17.62), 17.34 (5.15, 58.36), and 11.16 (2.16, 57.62) for lusutrombopag. Regarding bleeding, the placebo group had the highest probability of bleeding, whereas lusutrombopag had the lowest risk of bleeding when compared to the placebo. Adverse events were slightly higher in patients receiving rituximab than in those receiving placebo or other treatments. Overall, this meta-analysis showed that avatrombopag may yield the highest efficacy because it has the most favorable balance of benefits and acceptability.

Project description:IntroductionA network meta-analysis (NMA) was performed to assess the efficacy and safety of avatrombopag, relative to eltrombopag, romiplostim, and fostamatinib, for patients with chronic immune thrombocytopenia (ITP) not responding adequately to corticosteroids.MethodsA systematic search of publication and clinical trial databases was conducted to identify relevant randomized controlled trials (RCTs) and observational studies. Data from eligible studies were extracted and analyzed in a Bayesian framework using relative effect sizes vs placebo. Outcomes included durable platelet response; need for rescue therapy; reduction in use of concomitant ITP medication; incidence of any or World Health Organization (WHO) grade 2-4 bleeding events, and any adverse events. Results were reported as odds ratios or incidence rate ratios (IRR) with 95% credible intervals (CrIs).ResultsThe NMA included seven phase 3 RCTs. Compared with placebo, avatrombopag was associated with statistically significant improvements in durable platelet response, reduction in use of concomitant ITP medication, and incidence of any bleeding events. Statistically significant differences vs placebo were also observed for durable platelet response and need for rescue therapy (eltrombopag, romiplostim, and fostamatinib); reduction in use of concomitant ITP medication (eltrombopag and romiplostim); incidence of any bleeding events (fostamatinib); and incidence of WHO grade 2-4 bleeding events (romiplostim and fostamatinib). No statistically significant differences were observed for any adverse events. Avatrombopag was associated with a statistically significant lower incidence of any bleeding events vs eltrombopag (IRR 0.38 [95% CrI 0.19, 0.75]) and romiplostim (IRR 0.38 [95% Crl 0.17, 0.86]); no other between-treatment differences were observed.ConclusionIn this NMA, avatrombopag significantly increased the chance of achieving durable platelet response and reducing the use of concomitant ITP medication vs placebo, and significantly reduced the incidence of any bleeding events compared with placebo, eltrombopag, and romiplostim. The study aims to help guide clinicians managing patients with chronic ITP and insufficient response to previous treatment.

Project description:BACKGROUND:Sepsis is still a common critical disease with high morbidity and mortality in intensive care unit. Despite published guidelines for sepsis, development of antibiotic therapy and advanced organ support technologies, the mortality of sepsis patients is still 25% or more. It is necessary to distinguish the subtypes of sepsis, and the targeted therapy for the patients need to be explored. Platelets have various biological functions in hemostasis and thrombosis, host defense, inflammatory/immune responses and tissue repair/regeneration. Moreover, severe thrombocytopenia or sustained thrombocytopenia was closely associated with multiply organ dysfunction and higher mortality in sepsis patients. The clinical therapies for thrombocytopenia are platelet transfusion and platelet-elevating drugs. However, platelet transfusion has many defects in clinical practice in sepsis patients, and the impact of platelet-elevating drugs for sepsis patients is still unclear. RESCUE trial is aim to explore the effect of a platelet-elevating drug, recombinant human thrombopoietin (rhTPO), as an effective rescue therapy on sepsis patients with acute severe thrombocytopenia. METHODS:It is a randomized, open-label, multi-center, controlled trial in 5 tertiary academic hospitals including medical, surgical or general ICUs. In this study, a total of 200 sepsis patients with severe thrombocytopenia will be randomly assigned in a 1:1 ratio to the control and rhTPO group. The patients will be followed up to 28?days after randomization. All patients in two groups receive the same treatment based on the guideline of Surviving Sepsis Campaign. Primary outcome is 28-day mortality. Secondary outcomes are the changes of PCs, blood transfusion, biomarkers of infection and organ function, days free from advanced organ support, drug-related adverse events, the length of ICU and hospital stay. DISCUSSION:RESCUE trial is the first randomized controlled trial to explore the impact of rhTPO for severe thrombocytopenia in sepsis patients diagnosed by sepsis-3.0 standard. Furthermore, RESCUE trial results will be of significant clinical value on the targeted therapy and add clinical evidence that rhTPO is an effective rescue therapy for these sepsis patients.
