Thymoglobulin vs. ATG-Fresenius as Induction Therapy in Kidney Transplantation: A Bayesian Network Meta-Analysis of Randomized Controlled Trials.

ABSTRACT: Background: Thymoglobulin (THG) and antithymocyte globulin-Fresenius (ATG-F) have not been compared directly as induction therapies in kidney transplantation. Materials and Methods: We performed a Bayesian network meta-analysis to compare THG with ATG-F by pooling direct and indirect evidence. Surface under the cumulative ranking curve (SUCRA) values were used to compare the superiority of one method over the other. Results: A total of 27 randomized controlled trials (RCT) were eligible for the network meta-analysis. Efficacy endpoints, as well as safety indicators, were statistically comparable. For efficacy endpoints, THG seemed inferior to ATG-F in preventing delayed graft function [odds ratio (OR): 1.27; SUCRA: 78% vs. 58%], patient deaths (OR: 2.78; SUCRA: 83% vs. 34%), and graft loss (OR: 1.40; SUCRA: 83% vs. 59%), but superior to ATG-F in biopsy-proven acute rejection (BPAR; OR: 0.59; SUCRA: 78% vs. 39%) and steroid-resistant BPAR prevention (OR: 0.61; SUCRA: 76% vs. 49%) within the first year. For safety endpoints, THG was associated with higher risk of infection (OR: 1.49, SUCRA: 79% vs. 54%), cytomegalovirus infection (OR: 1.04; SUCRA: 40% vs. 37%), de novo diabetes (OR: 1.10; SUCRA: 90% vs. 30%), and malignancy (OR: 8.40; SUCRA: 89% vs. 6%) compared to ATG-F. A subgroup analysis of patients at high risk for immunologic complications revealed similar results, but THG performed better for graft loss (OR: 0.82; SUCRA: 68% vs. 54%). Conclusion: ATG-F seemed to be more effective than THG in improving the short-term kidney transplantation outcomes. Prospective head-to-head comparison of THG and ATG-F with larger sample sizes and longer follow-up is still required.

Project description:BACKGROUND:Complicated intra-abdominal infections (cIAIs) are common in clinical practice, caused by a mixture of aerobic and anaerobic bacteria, increase the risk of mortality. Carbapenems and tigecycline (TGC) are recommended for antimicrobial therapies for cIAIs. OBJECTIVE:To compare the effectiveness and safety of different carbapenems vs TGC for the treatment of cIAIs. METHODS:PubMed, Embase, Medline (via Ovid SP) and Cochrane library databases were systematically searched. We included randomized controlled trials (RCTs) comparing different carbapenems vs TGC for the treatment of cIAIs. The pooled odds ratio (OR) with 95% credible interval (CrI) was calculated by Markov chain Monte Carlo methods. We estimated summary ORs using pairwise and network meta-analysis with random effects. RESULTS:Fifteen studies involving 6745 participants were included in the analysis. Five different carbapenems and TGC were ultimately evaluated in this study. Although, the efficacy of carbapenems and TGC by ORs with corresponding 95% CrIs had not yet reached statistical differences, the cumulative rank probability indicated that clinical treatment success from best to worst was doripenem (DOPM), meropenem (MEPM), imipenem/cilastatin (IC), biapenem (BAPM), TGC and imipenem/cilastatin/relebactam (ICRB); microbiological treatment success from best to worst was DOPM, MEPM, IC, BAPM, ICRB and TGC. As for the risk of adverse events (AEs), TGC showed higher risk of AEs compared with IC (OR = 1.53, 95% CrI = 1.02-2.41), the remain antibiotic agents from lower to higher was MEPM, IC, BAPM, DOPM, ICRB and TGC. The risk of mortality from lower to higher was BAPM, DOPM, MEPM, IC, TGC and ICRB. CONCLUSION:No differences in clinical and microbiological outcomes were observed between different carbapenems and TGC. Balancing the evidence for drug efficacy and side effects, DOPM appears to be the best available treatment for cIAIs. Therefore, it is reasonable to consider that DOPM is one of the best carbapenem monotherapy for cIAIs. MEPM and IC was also associated with higher rates of clinical and microbiological treatment success following DOPM. Empiric antimicrobial treatment of patients with cIAIs should be selected in light of the local bacterial epidemiology and patterns of resistance.

Project description:ObjectiveThe aim of this meta-analysis was to evaluate the therapeutic effects of mesenchymal stromal cells (MSCs) versus traditional regimens for induction therapy in kidney transplantation (KT), especially the safety of MSC infusion, practicability of MSCs as induction therapy agents, and posttransplant complications.MethodsPubMed, Embase, EBSCO, Ovid, and the Cochrane Library were searched for prospective clinical trials that compared MSCs with traditional regimens for induction therapy in KT.ResultsFour trials were included, including a total of 197 patients. The pooled results revealed that MSC therapy had a lower 1-year infection rate than did the traditional therapies (RR = 0.65, 95% CI: 0.46-0.9, P = 0.01). There were no significant differences between the two protocols regarding the 1-year acute rejection (AR) rate (RR = 0.77, 95% CI: 0.41-1.45, P = 0.42), 1-year graft survival rate (RR = 0.99, 95% CI: 0.95-1.03, P = 0.74), delayed graft function (DGF) rate (RR = 0.54, 95% CI: 0.21-1.38, P = 0.2) and renal graft function at 1 month (MD = -1.56, 95% CI: - 14.2-11.08, p = 0.81), 3 months (MD = 0.15, 95% CI: - 5.63-5.93, p = 0.96), 6 months (MD = - 1.95, 95% CI: - 9.87-5.97, p = 0.63), and 12 months (MD = - 1.13, 95% CI: - 7.16-4.89, p = 0.71) postsurgery. Subgroup analysis demonstrated that the 1-year AR rate, 1-year graft survival rate, DGF rate, and renal graft function at 12 months postsurgery did not significantly differ between the low-dose calcineurin inhibitor (CNI) group and the standard-dose CNI group, indicating the potential benefits of successful CNI sparing in combination with MSC treatment. Moreover, when MSCs were applied as an alternative therapy rather than an additional therapy or allogeneic MSCs were utilized instead of autologous MSCs, all of the outcomes mentioned above were comparable.ConclusionInduction therapy with MSCs is safe and has similar immune response modulation effects to those of traditional regimens in the short term in KT recipients. However, regarding the long-term effects, as suggested by the 1-year infection rate and the potential of CNI sparing, MSC therapy has significant advantages. However, these advantages should be further verified in more well-designed, multicenter randomized controlled trials (RCTs) with large sample sizes and long follow-up periods.

Project description:Background: We provided a comprehensive evaluation of efficacy of available treatments for coronavirus disease 2019 (COVID-19). Methods: We searched for candidate COVID-19 studies in WHO COVID-19 Global Research Database up to August 19, 2021. Randomized controlled trials for suspected or confirmed COVID-19 patients published on peer-reviewed journals were included, regardless of demographic characteristics. Outcome measures included mortality, mechanical ventilation, hospital discharge and viral clearance. Bayesian network meta-analysis with fixed effects was conducted to estimate the effect sizes using posterior means and 95% equal-tailed credible intervals (CrIs). Odds ratio (OR) was used as the summary measure for treatment effect. Bayesian hierarchical models were used to estimate effect sizes of treatments grouped by the treatment classifications. Results: We identified 222 eligible studies with a total of 102,950 patients. Compared with the standard of care, imatinib, intravenous immunoglobulin and tocilizumab led to lower risk of death; baricitinib plus remdesivir, colchicine, dexamethasone, recombinant human granulocyte colony stimulating factor and tocilizumab indicated lower occurrence of mechanical ventilation; tofacitinib, sarilumab, remdesivir, tocilizumab and baricitinib plus remdesivir increased the hospital discharge rate; convalescent plasma, ivermectin, ivermectin plus doxycycline, hydroxychloroquine, nitazoxanide and proxalutamide resulted in better viral clearance. From the treatment class level, we found that the use of antineoplastic agents was associated with fewer mortality cases, immunostimulants could reduce the risk of mechanical ventilation and immunosuppressants led to higher discharge rates. Conclusions: This network meta-analysis identified superiority of several COVID-19 treatments over the standard of care in terms of mortality, mechanical ventilation, hospital discharge and viral clearance. Tocilizumab showed its superiority compared with SOC on preventing severe outcomes such as death and mechanical ventilation as well as increasing the discharge rate, which might be an appropriate treatment for patients with severe or mild/moderate illness. We also found the clinical efficacy of antineoplastic agents, immunostimulants and immunosuppressants with respect to the endpoints of mortality, mechanical ventilation and discharge, which provides valuable information for the discovery of potential COVID-19 treatments.
