Expert opinion on pharmacotherapy. 2023;24(6):763-774
Abstract
INTRODUCTION In this paper, we systematically review the efficacy and safety of thrombopoietin receptor agonists (TPORAs) for treatment of persistent and chronic immune thrombocytopenia (ITP) in children and adults. METHODS We searched PubMed, MEDLINE, ScienceDirect, Scopus, EMbase and the Cochrane Library to collect randomized controlled trials (RCTs) of TPO-RAs which including avatrombopag hetrombopag eltrombopag and romiplostim treated persistent and chronic ITP from their earliest records to February 2022. RESULTS We included 15 RCTs with a total of 1563 patients. There were ten trials of adults and five trials of children. The results of meta-analysis showed that in adult patients, patients treated with TPO-RAs had longer duration of platelet response, higher platelet response rate, lower use of rescue therapy, and lower incidence of bleeding events, and similar incidence of adverse events compared with placebo. Except for the incidence of any bleeding, the results in children were consistent with those in adults. The network meta-analysis of data on overall platelet response rates in adults showed that avatrombopag was more effective than eltrombopag and hetrombopag. CONCLUSIONS TPO-RAs has better efficacy and higher safety in the treatment of ITP. And the overall response rate of avatrombopag in adults was higher than that in eltrombopag and hetrombopag.

Pharmacological research. 2022;182:106345
Abstract
OBJECTIVE We aimed at comparing the efficacy of intravenous and oral iron supplementations for the treatment of iron deficiency (ID) in patients with heart failure (HF). METHODS We searched the PubMed, Cochrane, and Embase databases from inception to January 15, 2022. We included randomized controlled trials enrolling patients with HF who were treated for ID with intravenous iron supplements, oral iron supplements, or placebo. The primary outcomes were all-cause death, cardiovascular mortality, and hospitalization for heart failure. The secondary outcomes were evaluated through the six-minute walking test (6MWT) and the Kansas City Cardiomyopathy Questionnaire (KCCQ). RESULTS The network meta-analysis included sixteen studies. Compared to placebo/control groups, intravenous iron supplements did not decrease all-cause death (0.69, 0.39-1.23) or cardiovascular mortality (0.89, 0.66-1.20). After 12 weeks, a reduced hospitalization for heart failure was associated with the administration of intravenous iron supplementations (0.58, 0.34-0.97). The most significant improvements regarding 6MWT (44.44, 6.10-82.79) and KCCQ (5.96, 3.19-8.73) were observed with intravenous iron supplements. Oral iron supplements reduced hospitalization for heart failure (0.36, 0.14-0.96) and all-cause death (0.34, 0.12-0.95), but did not influence the 6MWT (29.74, -47.36 to 106.83) and KCCQ (0.10, -10.95 to 11.15). CONCLUSIONS Administering intravenous iron supplements for ID in patients with HF improves their exercise capacity and quality of life. In order to reduce hospitalizations for heart failure, the supplementation should be administered for more than 12 weeks. Although oral iron supplements did not improve exercise capacity and quality of life, they could reduce all-cause death and hospitalizations for heart failure.

Journal of plastic, reconstructive & aesthetic surgery : JPRAS. 2021
Abstract
BACKGROUND Autologous fat grafting (FG) is a popular technique for soft-tissue augmentation, but the fat survival rate is unpredictable. Platelet-rich plasma (PRP) has emerged as an adjuvant to enhance fat graft survival. OBJECTIVES This literature review and meta-analysis aimed to investigate the effect of PRP on the survival rate of fat grafting. METHODS A comprehensive systematic literature search was done to identify clinical studies on PRP and fat cotransplantation in PubMed, Cochrane Library, Web of Science, and EMBASE databases up to May 2020. The reference lists of selected articles were reviewed to identify any additional related articles. A meta-analysis was conducted to compare PRP + FG and conventional FG in terms of fat graft survival rate, patient satisfaction rate, and recovery time after surgery. RESULTS Eleven studies consisting of 1125 patients were analyzed. Patients were followed up from 3 to 24 months post-FG. The fat survival rate varied from 20.5% to 54.8% in FG alone and from 24.1% to 89.2% in the PRP + FG groups. The survival rate was significantly higher and recovery time was significantly lower in the PRP + FG group than in the FG alone group. However, there was no significant difference in the patient satisfaction rate between the groups. CONCLUSIONS This study demonstrates that PRP-enhanced fat transplantation has better efficacy than conventional fat grafting. Further studies are required to provide the optimum concentration of PRP and the long-term efficacy of the technique. There is not enough evidence to compare the rate of complications with PRP and fat cotransplantation and conventional fat grafting.

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.

Abstract
INTRODUCTION To examine the effects and safety of oxytocin administered intramuscularly or intravenously for preventing postpartum hemorrhage (PPH) in the third stage of labor after vaginal deliveries. MATERIAL AND METHODS Before data extraction, the review was registered with the PROSPERO International Prospective Register of Systematic Reviews (registration No. CRD42019145912). We searched the published electronic databases, including Medline, EMBASE, PubMed, Web of Science, CNKI, VIP, Wanfang, the Cochrane Library, clinicaltrial.gov and PROSPERO database, from their inception until February 2019. We included all randomized controlled trials (RCTs) comparing intramuscular and intravenous oxytocin administered just after the birth of the anterior shoulder or soon after the birth of the baby during a vaginal delivery. The primary outcomes were the incidence of PPH and severe PPH. PPH was defined as a blood loss ≥500 ml within 24 hours after vaginal birth. Severe PPH refers to a clinically estimated blood loss equal to or greater than 1000 mL within 24 hours after vaginal birth. Statistical heterogeneity was assessed by the I(2) test, the Cochran Q statistic and the Galbraith plot for heterogeneity. RESULTS Six RCTs, including 7320 women undergoing vaginal delivery, were identified in the meta-analysis. Women who were randomized to have intravenous oxytocin for the third stage of labor had a significantly lower incidence of PPH (relative risk 1.35, 95% CI 1.11-1.64, p = 0.003), severe PPH (relative risk 1.61, 95% CI 1.05-2.46, p = 0.03) and blood transfusion (relative risk 2.50, 95% CI 1.37-4.59, p = 0.003) compared with those who were randomized to have intramuscular oxytocin during the third stage of labor after vaginal delivery. There was no significant difference with regard to changes in hemoglobin level, third stage of labor duration, mean postpartum blood loss, or the incidences of a need for additional uterotonics and of retained placenta or manual removal of placenta between groups. CONCLUSIONS For women in the third stage of labor who are undergoing a vaginal delivery, the use of intravenous oxytocin reduces the incidence of PPH, severe PPH and blood transfusion and does not increase the risk of adverse effects compared with intramuscular oxytocin.

Huang P, Guo Y, Li B, Liu Q
Frontiers in pharmacology. 2019;10:1492
Abstract
Purpose: The meta-analysis aims to evaluate the efficacy and safety of terlipressin compared with norepinephrine for septic shock. Materials and Methods: The relevant studies from MEDLINE, Cochrane Library, Embase were searched by two independent investigators. A variety of keywords were used to search the studies. Stata software (version 11.0, Stata Corp LP, College Station, TX, USA) was used for statistical analysis. Results: A total of six studies were identified and incorporated into the meta-analysis. The results showed that there was no difference for 28-day mortality (RR = 0.99, 95% CI = [0.85,1.15], P = 0.849), AE (RR = 2.54, 95% CI = [0.58,11.08], P = 0.214), and MAP (SMD = -0.10, 95% CI = [-0.35,0.14], P = 0.405), OI, urinary output, Scr, total bilirubin, ALT, and AST between TP group and NE group. While TP could decrease HR at 24 and 48 h compared with NE. Conclusions: Current results suggest that terlipressin showed no added survival benefit for septic shock when compared with norepinephrine, while terlipressin could decrease heart rate in the late phase of septic shock compared with norepinephrine without further liver and kidney injury.

Liu Q, Geng P, Shi, Wang Q, Wang P
International Journal of Surgery (London, England). 2018;54((Pt A):):105-112
Abstract
OBJECTIVE To compare the efficacy and safety of tranexamic acid and aminocaproic acid for reducing blood loss and transfusion requirements after total knee and total hip arthroplasty. METHODS We conduct electronic searches of Medline (1966-2017.11), PubMed (1966-2017.11), Embase (1980-2017.11), ScienceDirect (1985-2017.11) and the Cochrane Library (1900-2017.11). The primary outcomes, including total blood loss, hemoglobin decline and transfusion requirements. Secondary outcomes include length of hospital stay and postoperative complications such as the incidence of deep vein thrombosis and pulmonary embolism. Each outcome is combined and calculated using the statistical software STATA 12.0. Fixed/random effect model is adopted based on the heterogeneity tested by I(2) statistic. RESULTS A total of 1,714 patients are analyzed across three randomized controlled trials (RCTs) and one non-RCT. The present meta-analysis reveals that TXA is associated with a significantly reduction of total blood loss and postoperative hemoglobin drop compared with EACA. No significant differences are identified in terms of transfusion rates, length of hospital stay, and the incidence of postoperative complications. CONCLUSION Although total blood loss and postoperative hemoglobin drop are significant greater in EACA groups, there is no significant difference between TXA and EACA groups in terms of transfusion rates. Based on the current evidence available, higher quality RCTs are still required for further research.

Tan J, Chen H, Liu Q, Chen C, Huang W
Journal of Surgical Research. 2013;184((2):):880-7.
Abstract
BACKGROUND To evaluate the effectiveness and safety of tranexamic acid (TEA) treatment in reducing perioperative blood loss and transfusion for patients receiving primary unilateral total knee arthroplasty (TKA) and to explore the most effective and safe protocol. MATERIALS AND METHODS This study was based on Cochrane methodology for conducting meta-analyses. Only randomized controlled trials were eligible for this study. The participants were adults who had undergone primary unilateral TKA. The Review Manager Database (RevMan version 5.0, The Cochrane Collaboration, 2008) was used to analyze selected studies. RESULTS Nineteen randomized controlled trials involving 1114 patients were included. The use of TEA reduced postoperative drainage by a mean of 290 mL (95% confidence interval [CI] -385 to -196], total blood loss by a mean of 570 mL (95% CI -663 to -478), the number of blood transfusions per patient by 0.96 units (95% CI -1.32 to -0.59), and the volumes of blood transfusions per patient -440 mL (95% CI -518 to -362). TEA led to a significant reduction in the proportion of patients requiring blood transfusion (relative risk 0.39). There were no significant differences in venous thromboembolism or other adverse events among the study groups. CONCLUSIONS Intravenous TEA could significantly reduce perioperative blood loss and blood transfusion requirements following primary unilateral TKA. Its application is not associated with increased risk of venous thromboembolisms or other adverse events. Copyright 2013 Elsevier Inc. All rights reserved.
