Patients received kidney transplantation (KTR) have a low seroconversion rate after vaccination. Our objective was to compare the seroconversion rates and adverse effects of additional different vaccinations in KTR patients in existing studies. Databases such as PubMed, Cochrane Library, Web of Science, Embase, ClinicalTrials.gov and others. Three high-quality RCT were included and showed no statistical difference in seroconversion rates between the two vaccines (RR = 0.93[0.76,1.13]). There was no statistical difference in seroconversion rates between the sexes, for men (RR = 0.93[0.69,1.25]) and women (RR = 0.91[0.62,1.33]). Among the adverse effects there was no statistically significant difference in fever (RR = 1.06[0.44,2.57]), while for injection site pain there was a statistically significant difference (RR = 1.14[1.18,1.84]). There was no significant difference in seroconversion rates in patients with KTR who received the two additional vaccines. Patients injected with the viral vector vaccine were less painful than those injected with the mRNA vaccine.

The long-term mortality of kidney transplantation patients with atypical hemolytic uremic syndrome remains high, and the efficacy of the main treatment eculizumab is still controversial.


A comprehensive systematic review and meta-analysis of clinical trials using eculizumab in renal transplant patients with atypical hemolytic uremic syndrome was conducted to evaluate the efficacy of this therapy and its impact on renal function.


A comprehensive systematic search was conducted across multiple reputable databases, including Ovid (MEDLINE, EMBASE), PubMed, and the Cochrane Library (since database inception), to identify relevant studies exploring the use of eculizumab in patients with atypical hemolytic uremic kidney transplantation. Various renal function parameters, such as dialysis, rejection, glomerular filtration rate, serum creatinine, lactate dehydrogenase, and platelet count, along with patient relapse rates, were extracted and summarized using a combination of robust statistical methods, including fixed effects, random effects, and general inverse variance methods.


Eighteen trials with 618 subjects were analyzed. Our analysis suggests that the use of eculizumab is associated with a reduced likelihood of AHUS recurrence (odds ratio (OR) = 0.05, 95% CI: 0.00-0.13), as well as a significant reduction in the need for dialysis (odds ratio (OR) = 0.13, 95% CI: 0.01-0.32). Additionally, eculizumab treatment led to lower serum creatinine levels (mean differences (MD) = 126.931μmoI/L, 95% CI: 115.572μmoI/L-138.290μmoI/L) and an improved glomerular filtration rate (mean differences (MD) = 59.571 ml/min, 95% CI: 57.876 ml/min-61.266 mL/min). Our results also indicate that the use of eculizumab reduces the likelihood of rejection (odds ratio (OR) = 0.09, 95% CI: 0.01-0.22). Furthermore, the drug was effective in improving platelet counts (×10∧9/L) (mean differences (MD) = 163.421, 95% CI: 46.998-279.844) and lactate dehydrogenase levels (mean differences (MD) = 336.608 U/L, 95% CI: 164.816 U/L-508.399 U/L).


Based on the meta-analysis, treatment with eculizumab can reduce dialysis rates and improve patients' quality of life by enhancing renal function.

The systematic review and meta-analysis were conducted for COVID-19 infections in kidney transplant patients. Recent research on this topic was still scarce and limited meta-analysis research discussion, specific to some risks or treatment in kidney transplantation patients with COVID-19 infection. Therefore, this article demonstrated the fundamental steps to conducting systematic review and meta-analysis studies to derive a pooled estimate of predictor factors of worse outcomes in kidney transplant patients with positive for the SARS-CoV- 2 test•PICOT Framework to determine the research scope•PRISMA strategy for study selection•Forest Plot for meta-analysis study.

CET Conclusion
Reviewer: Mr John O'Callaghan, Centre for Evidence in Transplantation, Nuffield Department of Surgical Sciences University of Oxford
Conclusion: This is a well-conducted systematic review that searched multiple databases and included data from 966 renal transplant patients with FSGS (38% recurrence after transplantation). A review protocol was recorded in advance and the literature search and data extraction was completed in duplicate. Significant heterogeneity was identified between studies and was not explored by the authors with sensitivity analysis. This identified one study as a key source of heterogeneity, that was then later removed from statistical analysis. Publication bias was also checked statistically and was only present for one risk factor analysis (age at transplantation); correcting for this had no effect on the pooled estimate. In summary, this study showed that the overall recurrence risk of FSGS after renal transplantation is high. Age at transplant, age at onset, time from diagnosis to kidney failure, proteinuria prior to transplant, related donor and native nephrectomy were all associated with a higher risk of FSGS recurrence. Multiple other risk factors were examined and not found to be associated with risk of recurrence of FSGS: HLA mismatch, duration of dialysis, sex, living donor, tacrolimus and previous transplant.

Clinical Impact Rating 3
Review: Whilst transplantation is the treatment of choice for renal failure due to focal segmental glomerular sclerosis (FSGS), it is one of the few indications for transplantation with a known risk of recurrent disease in the transplant kidney that can affect graft survival post-transplant. Treatments such as pre-emptive plasmapheresis with or without rituximab have been used to prevent or treat post-transplant recurrence, but the evidence for effectiveness is limited (1). A number of publications have attempted to correlate demographic and clinical features with risk of recurrence post-transplant. In a recent systematic review and meta-analysis, Bai and colleagues have attempted to summarise and synthesise this literature (2). They identified 22 studies with 966 patients, showing an overall rate of FSGS recurrence of 38%. Risk factors for recurrence were identified as younger age at transplant, older age of disease onset, shorter time from diagnosis to kidney failure, higher levels of proteinuria prior to transplant, a related living donor transplant and native nephrectomy. The review methodology was sound, with searches in multiple databases, multiple reviewers screening the literature and an evaluation of risk of bias. As might be expected when exploring retrospective cohort studies, there was heterogeneity seen in some outcomes, in particular age at transplant and pre-transplant proteinuria. Most underlying studies included in the meta-analysis explored risks in univariate analysis, without correction for confounding, and there is no way in meta-analysis to explore the interactions between risks. Limited data are available on the distinction between primary and secondary FSGS, and the impact of testing for genetic mutations and risk of recurrence (3). Despite the limitations, the review still provides a useful guide when assessing patients with FSGS for transplantation. The findings allow us to stratify risk of recurrence and set realistic expectations during the consent process. References 1. Boonpheng B, Hansrivijit P, Thongprayoon C et al.

To systematically review the incidence and risk factors for recurrent FSGS after kidney transplantation.


We searched PubMed, Embase, Medline, Web of Science, the Cochrane Library, CNKI, CBMdisc, Wanfang, and Weipu for case-control studies related to recurrent FSGS from the establishment until October 2022. The protocol was registered on PROSPERO (CRD42022315448). Data were analyzed using Stata 12.0, with odds ratios (counting data) and standardized mean difference (continuous data) being considered as effect sizes. If the I2 value was greater than 50%, the random-effects model was used; otherwise, a fixed-effects model was used. A meta-analysis on the incidence and risk factors for recurrent FSGS after kidney transplantation was performed.


A total of 22 studies with 966 patients and 12 factors were included in the meta-analysis. There were 358 patients with recurrent FSGS and 608 patients without FSGS after kidney transplantation. The results showed that the recurrence rate of FSGS after kidney transplantation was 38% (95% CI: 31%-44%). Age at transplantation (SMD = -0.47, 95% CI -0.73 to -0.20, p = .001), age at onset (SMD = -0.31, 95% CI -0.54 to -0.08, p = .008), time from diagnosis to kidney failure (SMD = -0.24, 95% CI -0.43 to -0.04, p = .018), proteinuria before KT (SMD = 2.04, 95% CI 0.91 - 3.17, p < .001), related donor (OR 1.99, 95% CI 1.20 - 3.30, p = .007) and nephrectomy of native kidneys (OR 6.53, 95% CI 2.68 - 15.92, p < .001) were associated with recurrent FSGS, whereas HLA mismatches, duration of dialysis before KT, sex, living donor, tacrolimus use and previous transplantation were not associated with recurrent FSGS after kidney transplantation.


The recurrence of FSGS after kidney transplantation remains high. Clinical decision-making should warrant further consideration of these factors, including age, original disease progression, proteinuria, related donor, and nephrectomy of native kidneys.

Pre-emptive kidney transplantation (PEKT), i.e., transplantation performed before initiation of maintenance dialysis, is considered an ideal renal replacement therapy because there is no exposure to long-term dialysis therapy. Therefore, we summarized advantages/disadvantages of PEKT to assist in deciding whether kidney transplantation should be performed pre-emptively.


This study was registered with PROSPERO, CRD42021269163. Observational studies comparing clinical outcomes between PEKT and non-PEKT were included; those involving only pediatric recipients or simultaneous multi-organ transplantations were excluded. The PubMed/MEDLINE, Cochrane Library, and Ichushi-Web databases were searched on 1 August 2021. Studies were pooled using the generic inverse-variance method with random effects model, and risk of bias was assessed using ROBINS-I.


Seventy-six studies were included in the systematic review (sample size, 23-121,853; enrollment year, 1968-2019). PEKT patients had lower all-cause mortality (adjusted HR: 0.78 [95% CI 0.66-0.92]), and lower death-censored graft failure (0.81 [0.67-0.98]). Unadjusted RRs for the following outcomes were comparable between the two patient groups: cardiovascular disease, 0.90 (0.58-1.40); biopsy-proven acute rejection, 0.75 (0.55-1.03); cytomegalovirus infection, 1.04 (0.85-1.29); and urinary tract infection, 0.89 (0.61-1.29). Mean differences in post-transplant QOL score were comparable in both groups. The certainty of evidence for mortality and graft failure was moderate and that for other outcomes was very low following the GRADE classification.


The present meta-analysis shows the potential benefits of PEKT, especially regarding patient and graft survival, and therefore PEKT is recommended for adults with end-stage kidney disease.

Purpose: Solid organ transplant recipients (SOTR) have a high risk for severe COVID-19 infection; hence it is necessary to find alternative treatment strategies to protect these patients from the complications caused by the severe progression of the disease. This study aimed to determine the effectiveness of sotrovimab among SOTR with COVID-19.Materials and methods: A systematic literature search was conducted with relevant keywords to find studies that reported clinical outcomes regarding sotrovimab administration in SOTR outpatients with confirmed COVID-19 infection, who had mild-to-moderate symptoms.Results: Of 796 records found by a systematic search, only 14 met the inclusion criteria for reporting in a systematic review and only 6 enrolled in a meta-analysis. This meta-analysis indicated that SOTR outpatients with mild to moderate COVID-19 who received sotrovimab had lower likelihood of all-cause hospitalization (OR: 0.29, CI: 0.16, 0.52, p < 0.001), ICU admission (OR: 0.17, CI: 0.05, 0.64, p = 0.009) and mortality (OR: 0.15, CI: 0.03, 0.64, p = 0.010) within 30 days of drug infusion compared to controls.Conclusions: Our findings confirm that monoclonal antibody therapy with sotrovimab in SOTR is associated with better outcomes and consequently a reduced risk of disease progression in this high-risk population.

Small-for-size syndrome (SFSS) is a well-recognized complication following liver transplantation (LT), with up to 20% developing this following living donor LT (LDLT). Preventing SFSS involves consideration of factors before the surgical procedure, including donor and recipient selection, and factors during the surgical procedure, including adequate outflow reconstruction, graft portal inflow modulation, and management of portosystemic shunts. International Liver Transplantation Society, International Living Donor Liver Transplantation Group, and Liver Transplant Society of India Consensus Conference was convened in January 2023 to develop recommendations for the prediction and management of SFSS in LDLT. The format of the conference was based on the Grading of Recommendations, Assessment, Development, and Evaluation system. International experts in this field were allocated to 4 working groups (diagnosis, prevention, anesthesia, and critical care considerations, and management of established SFSS). The working groups prepared evidence-based recommendations to answer-specific questions considering the currently available literature. The working group members, independent panel, and conference attendees served as jury to edit and confirm the final recommendations presented at the end of the conference by each working group separately. This report presents the final statements and evidence-based recommendations provided by working group 2 that can be implemented to prevent SFSS in LDLT patients.

The immunogenicity and efficacy of COVID-19 vaccination varied by demographic, including solid organ transplant recipients on immunosuppressive therapy.


This purpose of this study is to assess seropositivity and seroconversion in solid-organ transplant recipients before and after third-dose COVID-19 vaccination.


This study is a systematic review and meta-analysis performed using PRISMA guidelines. To analyze clinical and cohort studies reporting immunologic response and seroconversion third-dose vaccination, a systematic search was performed using electronic databases (PubMed, Scopus, Cochrane, Directory of Open Access Journal (DOAJ), and Clinicaltrials.gov).


There were 18 full-text papers that could be analyzed qualitatively and quantitatively. After the third vaccination, the pooled rate seropositivity was 67.00% (95% CI 59.511; 74.047, I2 = 93.82%), and the pooled rate seroconversion was 52.51% (95% CI 44.03; 60.91, I2 = 92.15%). The pooled rate of seroconversion after the mRNA-based booster was 52.380% (95% CI 40.988; 63.649, I2 = 94.35%), and after the viral-vector-based booster was 42.478% (95% CI 35.222; 49.900, I2 = 0.00%).


Based on the analysis of immunologic responses and seroconversion findings, the third-dose vaccination of solid organ transplant recipients is an effective method in establishing better immunity against COVID-19.
