Meta-Analysis Review
BACKGROUND
Although previous studies have explored the correlation of interleukin (IL)-6 with mortality risk in dialysis patients, the findings have been conflicting. Hence, this meta-analysis aimed to comprehensively assess the use of IL-6 measurement for estimating cardiovascular mortality and all-cause mortality in dialysis patients.
METHODS
The Embase, PubMed, Web of Science, and MEDLINE databases were searched to identify relevant studies. After screening out the eligible studies, the data were extracted.
RESULTS
Twenty-eight eligible studies with 8370 dialysis patients were included. Pooled analyses revealed that higher IL-6 levels were related to increased cardiovascular mortality risk (hazard ratio [HR] = 1.55, 95% confidence interval [CI]: 1.20-1.90) and all-cause mortality risk (HR = 1.11, 95% CI: 1.05-1.17) in dialysis patients. Further subgroup analyses suggested that higher IL-6 levels were associated with elevated cardiovascular mortality in hemodialysis patients (HR = 1.59, 95% CI: 1.36-1.81) but not in peritoneal dialysis patients (HR = 1.56, 95% CI: 0.46-2.67). Moreover, sensitivity analyses indicated that the results were robust. Egger's test revealed potential publication bias among studies exploring the correlation of IL-6 levels with cardiovascular mortality (p = .004) and all-cause mortality (p < .001); however, publication bias was not observed when using Begg's test (both p > .05).
CONCLUSIONS
This meta-analysis reveals that higher IL-6 levels could indicate higher risks of cardiovascular mortality and all-cause mortality in dialysis patients. These findings suggest that monitoring IL-6 cytokine may help to enhance dialysis management and improve the general prognosis of patients.

Kidney transplant recipients and dialysis patients constitute a risk group for severe COVID-19. They are highly advised to get vaccinated according to the current guidelines. However, data on antibody response, cell responses and protection from events, and factors that might alter this response after a routine full series of vaccination remain incomplete for these populations. The aim of this article was to analyze the antibody responses after a full series of mRNA-based SARS-CoV-2 vaccination in kidney transplantation and dialysis patients and to define the factors that alter seroconversion status in these populations. In this systematic review, 18 studies investigating the antibody response to full vaccination with two doses of COVID-19 mRNA vaccines in hemodialysis, peritoneal dialysis, and kidney transplant patients were included. Kidney transplant and dialysis patients have a lower seroconversion rate after mRNA-based SARS-CoV-2 vaccination than the healthy population: 27.2% for kidney transplantation, 88.5% for dialysis patients while all healthy control in these studies seroconverted. Moreover, anti-S antibody titers were lower in seroconverted kidney transplantation or dialysis patients than in healthy control in all studies that assessed this variable. Older age and dialysis vintage, immunosuppressive or chemotherapy treatment, and lower serum albumin, white blood cell, lymphocyte and hemoglobin counts were associated with lower/no antibody response to vaccination. Dialysis patients and kidney transplant recipients have lower seroconversion rates after a full series of mRNA-based SARS-CoV-2 vaccination than the general population. Several factors are associated with an altered antibody response. A third dose could be considered in this patient group.

Review
Cephalexin is a first-generation β-lactam antibiotic used in adults and pediatrics to treat various streptococcal and staphylococcal infections. This review aims to summarize and evaluate all the pharmacokinetic (PK) data on cephalexin by screening out all pertinent studies in human beings following the per oral (PO) route. By employing different online search engines such as Google Scholar, PubMed, Cochrane Central, and Science Direct, 23 studies were retrieved, among which nine were in healthy subjects, five in diseased ones, and the remaining were drug-drug, drug-food, and bioequivalence-related. These studies were included only based on the presence of plasma concentration-time profiles or PK parameters, i.e., maximum plasma concentration (C), half-life (t) area under the curve from time 0-infinity (AUC and clearance (CL/F). A dose-proportional increase in AUC and C can be portrayed in different studies conducted in the healthy population. In comparison to cefaclor, C was recorded to be 0.5 folds higher for cephalexin in the case of renal impairment. An increase in AUC was seen in cephalexin on administration with probenecid, i.e., 117 µg.h/mL vs. 68.1 µg.h/mL. Moreover, drug-drug interactions with omeprazole, ranitidine, zinc sulfate, and drug-food interactions for cephalexin and other cephalosporins have also been depicted in different studies with significant changes in all PK parameters. This current review has reported all accessible studies containing PK variables in healthy and diseased populations (renal, dental, and osteoarticular infections, continuous ambulatory peritoneal dialysis) that may be favorable for health practitioners in optimizing doses among the latter.

INTRODUCTION
Peritoneal dialysis (PD)-associated peritonitis due to tuberculosis (TB) is associated with poor outcomes and optimal treatment strategies for this condition remain unknown. Our study aimed to: (i) systematically review the published literature on peritonitis caused by in patients on PD and (ii) review cases of peritonitis due to in patients on PD reported in Australia and New Zealand to determine the epidemiology, management strategies, and outcomes of this condition.
METHODS
A literature search of Medline, Scopus, Embase, ClinicalTrials.gov, Cochrane CENTRAL Register of Controlled Trials and Google Scholar for articles published from inception date to June 2022 was conducted. To be eligible, articles had to describe patient characteristics, initial anti-TB therapy, and treatment outcomes in all patients on PD with peritonitis caused by . Data from the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry of patients on PD who developed peritonitis due to between September 2001 and December 2020 were included and analyzed.
RESULTS
The systematic literature review identified 70 case studies (151 patients) and 8 cohort studies (97 patients), whereas the ANZDATA Registry identified 17 cases of peritonitis due to . Overall, in patients diagnosed with peritonitis due to , the rates of PD catheter removal and permanent transfer to hemodialysis (HD) were numerically higher in the ANZDATA Registry cases (82%) than in the case studies (23%) and cohort studies (20%). Observed all-cause mortality rates were also higher as observed in the case studies (33%) and cohort studies (26%) than in the ANZDATA Registry cases (6%).
CONCLUSION
Tuberculous peritonitis is uncommon in patients on PD and is associated with poor outcomes. Prospective studies are warranted to study the effect of retaining PD catheters after infection on patient outcomes.

Review
BACKGROUND
Cardiac valve calcification (CVC) is highly prevalent and a risk factor for adverse outcomes in patients with chronic kidney disease (CKD). This meta-analysis aimed to investigate the risk factors for CVC and association between CVC and mortality in CKD patients.
METHOD
Three electronic databases including PubMed, Embase, and Web of Science were searched for relevant studies up to November 2022. Hazard ratios (HR), odds ratios (OR), and 95% confidence intervals (CI) were pooled using random-effect meta-analyses.
RESULTS
22 studies were included in the meta-analysis. Pooled analyses showed that CKD patients with CVC were relatively older, had a higher body mass index, left atrial dimension, C-reaction protein level, and a declined ejection fraction. Calcium and phosphate metabolism dysfunction, diabetes, coronary heart disease, and duration of dialysis were all predictors for CVC in CKD patients. The presence of CVC (both aortic valve and mitral valve) increased the risk of all-cause and cardiovascular mortality in CKD patients. However, the prognostic value of CVC for mortality was not significant anymore in patients with peritoneal dialysis.
CONCLUSION
CKD patients with CVC had a greater risk of all-cause and cardiovascular mortality. Multiple associated factors for development of CVC in CKD patients should be taken into consideration by healthcare professionals to improve prognosis.

Comparative Study Meta-Analysis
BACKGROUND
Accurate comparisons of haemodialysis (HD) and peritoneal dialysis (PD) survival based on observational studies are difficult due to substantial residual confounding that arises from imbalances between treatments. Propensity score matching (PSM) comparisons confer additional advantages over conventional methods of adjustment by further reducing selection bias between treatments. We conducted a systematic review of studies that compared mortality between in-centre HD with PD using a PSM-based approach.
METHODS
A sensitive search strategy identified all citations in the PubMed, Cochrane and EMBASE databases from inception through November 2018. Pooled PD versus HD mortality hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated through random-effects meta-analysis. A subsequent meta-regression explored factors to account for between-study variation.
RESULTS
The systematic review yielded 214 citations with 17 cohort studies and 113 578 PSM incident dialysis patients. Cohort periods spanned the period 1993-2014. The pooled HR for PD versus HD was 1.06 (95% CI 0.99-1.14). There was considerable variation by country, however, mortality risks for PD versus HD remained virtually unchanged when stratified by geographical region with HRs of 1.04 (95% CI 0.94-1.15), 1.14 (95% CI 0.99-1.32) and 0.98 (0.87-1.10) for European, Asian and American cohorts, respectively. Subgroup meta-analyses revealed similar risks for patients with diabetes [HR 1.09 (95% CI 0.98-1.21)] and without diabetes [HR 0.99 (95% CI 0.90-1.09)]. Heterogeneity was substantial (I2 = 87%) and was largely accounted for by differences in cohort period, study type and country of origin. Together these factors explained a substantial degree of between-studies variance (R2 = 90.6%).
CONCLUSIONS
This meta-analysis suggests that PD and in-centre HD carry equivalent survival benefits. Reported differences in survival between treatments largely reflect a combination of factors that are unrelated to clinical efficacy.

Meta-Analysis
OBJECTIVE
For end-stage renal disease (ESRD), patients receiving kidney transplantation, peritoneal dialysis (PD) and hemodialysis (HD) are both appropriate modes of pre-transplant dialysis. The aim of this review is to assess the impact of pre-transplant PD compared to HD on kidney transplant outcomes in ESRD patients.
MATERIALS AND METHODS
A comprehensive search in digital databases, like PubMed, SCOPUS and EMBASE and a manual search were conducted to identify cohort studies comparing the kidney transplant outcomes of both pre-transplant dialysis modalities. The data were subjected to both qualitative and quantitative analysis. A meta-analysis was carried out to calculate the effect estimate for patient survival, graft survival and delayed graft function, death-censored graft survival, acute rejection-free graft survival, graft vessel thrombosis, urological complications, surgical complications, any infections, and onset of diabetes after transplantation. The qualities of the included studies were judged by the New-castle Ottawa scale.
RESULTS
The overall patient survival is shown to be better with patients who underwent pre-transplant PD compared to HD with OR 1.34 95% CI [1.11, 1.61], p = 0.002. Delayed graft function was found to be highly associated with HD compared to PD with OR 0.60 [0.52, 0.70], p<0.0001 with moderate heterogeneity (i2 = 48%). However, no difference was observed in terms of graft survival, complications, infections, and new onset of diabetes mellitus compared to patients undergoing pre-transplant HD.
CONCLUSIONS
Within the limitations of the review, it can be concluded that ESRD patients undergoing pre-transplant PD were found to have better patient survival and lower incidence of delayed graft function.

BACKGROUND AND OBJECTIVES
Compared with hemodialysis, home peritoneal dialysis alleviates the burden of travel, facilitates independence, and is less costly. Physical, cognitive, or psychosocial factors may preclude peritoneal dialysis in otherwise eligible patients. Assisted peritoneal dialysis, where trained personnel assist with home peritoneal dialysis, may be an option, but the optimal model is unknown. The objective of this work is to characterize existing assisted peritoneal dialysis models and synthesize clinical outcomes.
DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS
A systematic review of MEDLINE, Cochrane Central Register of Controlled Trails, Cochrane Database of Systematic Reviews, Embase, PsycINFO, and CINAHL was conducted (search dates: January 1995-September 2018). A focused gray literature search was also completed, limited to developed nations. Included studies focused on home-based assisted peritoneal dialysis; studies with the assist provided exclusively by unpaid family caregivers were excluded. All outcomes were narratively synthesized; quantitative outcomes were graphically depicted.
RESULTS
We included 34 studies, totaling 46,597 patients, with assisted peritoneal dialysis programs identified in 20 jurisdictions. Two categories emerged for models of assisted peritoneal dialysis on the basis of type of assistance: health care and non-health care professional assistance. Reported outcomes were heterogeneous, ranging from patient-level outcomes of survival, to resource use and transfer to hemodialysis; however, the comparative effect of assisted peritoneal dialysis was unclear. In two qualitative studies examining the patient experience, the maintenance of independence was identified as an important theme.
CONCLUSIONS
Reported outcomes and quality were heterogeneous, and relative efficacy of assisted peritoneal dialysis could not be determined from included studies. Although the patient voice was under-represented, suggestions to improve assisted peritoneal dialysis included using a person-centered model of care, ensuring continuity of nurses providing the peritoneal dialysis assist, and measures to support patient independence. Although attractive elements of assisted peritoneal dialysis are identified, further evidence is needed to connect assisted peritoneal dialysis outcomes with programmatic features and their associated funding models.

Meta-Analysis
CONTEXT
End-stage renal disease (ESRD) is the advanced stage of a progressive loss of kidney function. About 10% of all patients with lupus nephritis (LN) eventually progress to ESRD, which may necessitate renal replacement therapy (RRT), such as hemodialysis (HD), peritoneal dialysis (PD), and/or kidney transplant. Research hasn't confirmed which dialysis options, prior to kidney transplantation, are beneficial to patients' prognoses.
OBJECTIVE
The study intended to compare the risks-related to disease activity, exercise, all-cause infection, all-cause cardiovascular events, and mortality-of the use of HD and PD for LN-ESRD adults, as the initial alternative treatment before renal transplantation.
DESIGN
The research team performed a narrative review and analyzed the data obtained about clinical outcomes for HD and peritoneal dialysis. For the review, the research team searched the PubMed, EMBASE, and SCOPUS databases. The search used the keywords: end-stage renal disease, renal replacement therapy, hemodialysis and peritoneal dialysis.
SETTING
The study made in Affiliated Hospital of Hebei University, China.
PARTICIPANTS
The studies included 15 636 patients who had been diagnosed with LN-ESRD prior to renal transplantation.
OUTCOME MEASURES
For the data analysis, the research team divided the data into two groups, one of which included the data on the clinical outcomes for HD patientsand one of which included the data on the clinical outcomes for PD patients. The study evaluated four types of risks: lupus-flare risks, all-cause infection risks, all-cause cardiovascular events risk, and risk of mortality.
RESULTS
The 16 studies found in the review reported one or more outcomes of interest for the two dialysis modalities, HD and PD. The analysis of the data from the 16 studies showed that HD was associated with a higher risk than PD: (1) of lupus flares, with RR = 1.23 (confidence interval: 0.82, 1.85), but the difference didn't reach statistical significance (P = .31); (2) of all-cause infection risk, with RR = 1.02 (confidence interval: 0.66, 1.59), but the difference didn't reach statistical significance (P = .92); (3) of all-cause cardiovascular events, with RR = 1.44 (confidence interval: 1.02, 2.04), and the difference reached statistical significance (P = .04); and (4) of mortality risk, with RR = 1.29 (confidence interval: 0.95, 1.75), but the difference didn't reach statistical significance (P = .10).
CONCLUSIONS
The current study may have reference significance for clinical treatment of ESRD. Except for all-cause cardiovascular events in which PD was superior to HD, offering better outcomes, both treatment modalities provide more or less similar clinical outcomes as effective initial choices for RRT in LN-ESRD patients prior to renal transplant. The current research team, however, encourages further research on the question, addressing better the possible sources of biases encountered in the current study.

Meta-Analysis
Inconsistent investigations of the risk factors for all-cause mortality in patients undergoing peritoneal dialysis (PD) were reported. The present meta-analysis aimed to assess the impact of some clinical characteristics on the risk of mortality in PD patients. PubMed and Embase were systematically searched for studies evaluating the risk factors for all-cause mortality in PD patients. Hazard ratio (HR) and 95% confidence interval (CI) were derived using a random-effect or fixed-effect model considering the heterogeneity across studies. A total of 26 studies were included in this meta-analysis in accordance with the inclusion and exclusion criteria. Age, primary cardiovascular diseases, diabetes mellitus, and high level of alkaline phosphatase showed significant positive associations with elevated risk of all-cause and cardiovascular mortality in PD patients, while hemoglobin acted as a benefit factor. Furthermore, early onset of peritonitis, high peritoneal transport status, elevated body mass index and high-sensitivity C-reactive protein could also considerably increase the risk of all-cause mortality. The absolute serum level of magnesium, potassium, and uric acid required to improve survival in PD patients should be verified further. Multiple factors could affect the risk of mortality in PD patients.
