Meta-Analysis Review
AIMS
The association of renal function and linezolid-induced thrombocytopaenia (LIT) remains controversial. We performed a meta-analysis to determine whether impaired renal function is associated with an increased LIT risk.
METHODS
We conducted a systematic search of PubMed, EMBASE and the Cochrane Library from inception to February 2021 for eligible studies evaluating the relationship between renal function and LIT. Indicators of renal function included renal impairment (RI), severe RI, haemodialysis status, creatinine clearance rate (Ccr) and estimated glomerular filtration rate (eGFR). Unadjusted and adjusted estimates and 95% confidence intervals (CIs) were calculated separately using a random-effect model.
RESULTS
A total of 24 studies with 3580 patients were included in the meta-analysis. RI patients had an increased LIT risk compared to non-RI patients in both the unadjusted (OR 3.54; 95% CI 2.27, 5.54; I = 77.7%) and adjusted analyses (OR 2.51; 95% CI 1.82, 3.45; I = 17.9%). This association persisted in the subset of studies involving only patients receiving a fixed conventional dose (600 mg every 12 h) and other subgroup analyses by ethnicity, sample size and study quality. Moreover, the LIT risk was significantly higher in patients with severe RI and haemodialysis than in patients without severe RI and haemodialysis. The eGFR and Ccr were significantly lower in LIT patients than in non-LIT patients.
CONCLUSIONS
Impaired renal function is associated with an increased risk of LIT. A reduced linezolid dose may be considered in RI patients at a low risk of treatment failure, ideally guided by therapeutic drug monitoring.

INTRODUCTION
Despite antiretroviral (ARV) therapy reducing renal disease in human immunodeficiency virus overall, there is concern that certain ARVs, particularly tenofovir disoproxil fumarate (TDF) with or without a boosted protease inhibitor (PI), may reduce renal function over time. It is not known whether effects seen with PI-based regimens are independent, result from interactions with TDF coadministration, or are artefactual owing to inhibition of renal tubular creatinine transport by ritonavir or cobicistat pharmacoenhancement. The aim of this review was to conduct a systematic review of studies, weighted toward high-quality evidence, examining changes in renal function over time with PI-based regimens.
METHODS
PubMed, Embase, and Medline databases and conference abstracts were searched using pre-defined terms for English language articles, published up to and including August 12, 2013, describing changes in renal function over time with PI-based regimens. All available randomized controlled trials (RCTs) were selected; however, to reduce bias, only observational studies recruiting from more than one center and analyzing data from more than 1,000 patients were included. Evidence was qualitatively evaluated according to levels established by the Oxford Centre for Evidence-Based Medicine (OCEBM).
RESULTS
A total of 2,322 articles were retrieved by the initial search. Of these, 37 were selected for full review, comprising 24 RCTs (OCEBM Level 1 evidence: 4 reports of fully double-blinded or blinded with respect to the PI component). The remaining 20 RCTs and 13 observational studies qualified as OCEBM Level 2 evidence. Level 1 evidence showed initial but non-progressive increases in serum creatinine and corresponding decreases in estimated glomerular filtration rate (eGFR), suggesting an effect on renal tubular transport of creatinine. Level 2 evidence suggested that atazanavir and lopinavir especially in combination with TDF were associated with non-progressive reductions in eGFR over time, with a decreased risk for the development of chronic kidney disease (CKD) on cessation and without the development of advanced CKD or end-stage renal disease (ESRD); whether these reductions were independent or associated with interactions with coadministered TDF could not be established with certainty. Data on darunavir were insufficient to draw any conclusions. The principal limitation of the reviewed studies was the lack of standardization of creatinine measurements in virtually all studies and the lack of corroborative data on changes in proteinuria or other indices of renal function.
DISCUSSION
In this review, there was little evidence for progressive changes in eGFR, or the development of advanced CKD, or ESRD with lopinavir or atazanavir. Further long-term studies, employing a wide range of validated renal function assessments, are required to fully evaluate potential association of PIs with CKD.

Meta-Analysis
BACKGROUND
Sacubitril/valsartan, a new pharmacological class of angiotensin receptor neprilysin inhibitor, is beneficial to heart failure through blocking the degradation of natriuretic peptides and inhibiting renin-angiotensin-aldosterone system (RAAS) activation which also relate to the pathophysiologic mechanisms of chronic kidney disease (CKD). However, its effects on CKD remain unclear. To assess the efficacy and safety of sacubitril/valsartan for patients with CKD, we performed this meta-analysis.
METHODS
The Embase, PubMed and the Cochrane Library were searched for randomized controlled trials (RCTs) that compared sacubitril/valsartan with ACEI/ARBs in patients with CKD whose estimated glomerular filtration rate (eGFR) was below 60 mL/min/1.73 m. We adopted the Cochrane Collaboration tool for assessing the risk of bias. The effect size was estimated using the odds ratio (OR) with 95% confidence interval (CI).
RESULTS
Six trials with a total of 6217 patients with CKD were included. In terms of cardiovascular events, sacubitril/valsartan attenuated the risk of cardiovascular death or heart failure hospitalization (OR: 0.68, 95% CI 0.61-0.76, P < 0.00001, I = 43%). With respect to renal function, sacubitril/valsartan prevented the incidence of serum creatinine (Scr) elevation among patients with CKD (OR: 0.79, 95% CI 0.67-0.95, P = 0.01, I = 0%). Subgroup analysis about eGFR demonstrated that with long follow-up, sacubitril/valsartan significantly decreased the number of patients with more than 50% reduction in eGFR compared with ACEI/ARBs (OR: 0.52, 95% CI 0.32-0.84, P = 0.008, I = 9%). In patients with CKD, the incidence of end-stage renal disease (ESRD) was reduced with sacubitril/valsartan treatment, despite no statistically significant difference between the two groups (OR: 0.59, 95% CI 0.29-1.20, P = 0.14, I = 0%). As for the safety, we found that sacubitril/valsartan was associated with the occurrence of hypotension (OR: 1.71, 95% CI 1.15-2.56, P = 0.008, I = 51%). However, there was no trend towards increasing the risk of hyperkalemia in patients who received sacubitril/valsartan (OR: 1.09, 95% CI 0.75-1.60, P = 0.64, I = 64%).
CONCLUSION
This meta-analysis indicated that sacubitril/valsartan improved renal function and conferred effective cardiovascular benefits in patients with CKD, without serious safety issues being observed. Thus, sacubitril/valsartan may be a promising option for patients with CKD. Certainly, further large-scale randomized controlled trials are needed to confirm these conclusions.

Meta-Analysis Review
BACKGROUND
To assess the potential effects of telbivudine (LdT) and entecavir (ETV) on renal function in patients with chronic hepatitis B (CHB), we performed a meta-analysis of the relevant data available on these agents to evaluate their effects on the estimated glomerular filtration rate (eGFR) during treatment.
METHODS
The PubMed, EMBASE, Scopus, CNKI (China National Knowledge Infrastructure), Cochrane Library, and WanFang databases were searched for relevant articles appearing in the literature up to July 1, 2015. A total of 6 studies (1960 CHB patients) with 1-year eGFR outcomes were retrieved and analyzed.
RESULTS
Generally, the results of the 6 studies analyzed showed that eGFR was improved after LdT treatment, but was decreased after ETV treatment. Using a fixed-effects approach, the change in eGFR was found to be significantly different between LdT and ETV treatment (Z = 3.64; P = 0.0003). Whereas the eGFR was slightly decreased with ETV compared with baseline (-1.45 mL/min/1.73 m(2)), the eGFR was improved with LdT (2.99 mL/min/1.73 m(2)) after 1 year of treatment. An overall test of effect in the meta-analysis showed that the eGFR in LdT-treated patients was significantly improved after 1-year of treatment (Z = 3.71; P = 0.0002).
CONCLUSION
This meta-analysis has confirmed that LdT has a renal protective effect whereas ETV does not. However, whether the benefit on renal function outweighs the occurrence of resistance in specific clinical situations is not yet clear.

The interaction between acute heart failure (AHF) and renal dysfunction is complex. Several studies have evaluated the prognostic value of this syndrome. The aim of this systematic review, which includes non-selected samples, was to investigate the impact of different renal function variables on the AHF prognosis. The categories included in the studies reviewed included: creatinine, blood urea nitrogen (BUN), the BUN/creatinine quotient, chronic kidney disease, the formula to estimate the glomerular filtration rate, criteria of acute renal injury and new biomarkers of renal damage such as neutrophil gelatinase-associated lipocalin (NGAL and cystatin c). The basal alterations of the renal function, as well as the acute alterations, transient or not, are related to a worse prognosis in AHF, it is therefore necessary to always have baseline, acute and evolutive renal function parameters.

Current Urology Reports Apr 2020To present the latest evidence related to the impact of ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) on the renal function.
PURPOSE OF REVIEW
To present the latest evidence related to the impact of ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) on the renal function.
RECENT FINDINGS
Our review suggests that the overall renal function is not detrimentally affected by endourological interventions (URS, PCNL). This is however influenced by the preoperative renal function, presence of comorbidities such as diabetes and hypertension. For PCNL procedures, tract multiplicity, preoperative UTI, and postoperative bleeding also contribute to a decline in renal function. This review suggests that endourological interventions do not adversely affect renal function and tend to improve it in patients who do not have a poor renal function prior to the procedure. Several factors including poor preoperative renal function, diabetes, hypertension, and multiple percutaneous tracts appear to predispose patients to declining renal function after procedure, and these patients should be counseled for and followed up appropriately.

Meta-Analysis
PURPOSE
Erectile dysfunction has a lower prevalence in renal transplant recipients compared to dialysis patients. Despite this observation, the effect of renal transplantation on erectile function remains unknown. We aimed to assess the role of renal transplantation on erectile function and to determine potential factors improving or deteriorating erectile dysfunction.
MATERIALS AND METHODS
We conducted a systematic review and random effects meta-analysis of observational studies comparing erectile function preoperatively and postoperatively in renal transplant recipients (PROSPERO ID: CRD42020189580). Records reporting relevant outcomes were identified through search of PubMed®, Embase®, Cochrane Library and Scopus® databases from inception to September 2020. Judgment of the strength of evidence was performed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
RESULTS
We included 20 studies with 1,695 renal transplant recipients. At postoperative evaluation the number of patients with erectile dysfunction was reduced (RR 1.21, 95% CI 1.02-1.45, I=88%). Renal transplant recipients reported an improvement in erectile function (RR 2.53, 95% CI 1.44-4.44, I=90%) and the mean International Index of Erectile Function score increased by 3.04 points (95% CI 0.63-5.45, I=96%) after renal transplantation. These effects were not demonstrated in the sensitivity analysis. In individuals reporting severe erectile dysfunction, no favorable effect of renal transplantation was observed (RR 1.51, 95% CI 0.85-2.68, I=33%). For all outcomes the strength of evidence was considered low or very low due to methodological concerns and high heterogeneity among the included studies.
CONCLUSIONS
Renal transplantation improves erectile function and the risk of erectile dysfunction reduces postoperatively compared to preoperatively. However, evidence on the matter is mostly based on low quality data. More studies with standardized outcomes are needed to validate and strengthen our findings.

Meta-Analysis
BACKGROUND
Linezolid causes hematological toxicity, mostly thrombocytopenia, which leads to treatment discontinuation and failure. Recent studies revealed that during linezolid therapy, the incidence of treatment-related hematological toxicity is significantly higher in patients with decreased renal function (DRF) than in those with normal renal function. Linezolid monitoring is necessary due to the high frequency of hematological toxicity in patients with DRF and the relationship between blood concentration and safety. We performed a systematic review and meta-analysis to evaluate the safety correlation between DRF and trough monitoring.
METHODS
Articles published before June 24, 2022, on MEDLINE, Web of Sciences, Cochrane Register of Controlled Trials, and ClinicalTrials.gov were systematically analyzed. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using the Mantel-Haenszel method and the variable effects model.
RESULTS
The incidence of hematological toxicity was significantly higher in patients with DRF than in those without DRF (OR = 2.37; p < 0.001). Subgroup analysis, performed according to hematotoxicity classification, including thrombocytopenia, anemia, and pancytopenia, revealed a significantly higher incidence of thrombocytopenia (OR = 2.45; p < 0.001) and anemia (OR = 2.31; p = 0.006) in patients with DRF than in those without; pancytopenia (OR = 1.41; p = 0.80) incidences were not significantly higher. Based on a systematic review, linezolid trough concentrations > 6-7 μg/mL may be associated with an increased incidence of thrombocytopenia. However, no confidential threshold values for the development of thrombocytopenia were found in the area under the concentration curve values for children or adults.
CONCLUSION
We observed a high frequency of hematological toxicity during linezolid therapy in patients with DRF. To ensure safety, linezolid trough concentrations should be ≤6-7 μg/mL.

Which recipient pretransplant factors, such as MELD, renal function, sarcopenia, and recent sepsis influence suitability for and outcome after living donor liver transplantation? A systematic review of the literature and expert panel recommendations.
BACKGROUND
Varied access to deceased donors across the globe has resulted in differential living donor liver transplant (LDLT) practices and lack of consensus over the influence of models for end stage liver disease (MELD), renal function, sarcopenia, or recent infection on short-term outcomes.
OBJECTIVES
Consider these risk factors in relation to patient selection and provide recommendations.
DATA SOURCES
Ovid MEDLINE, Embase, Scopus, Google Scholar, Cochrane Central.
METHODS
PRIMSA systematic review and GRADE.
PROSPERO ID
RD42021260809 RESULTS: MELD >25-30 alone is not a contraindication to LDLT, and multiple studies found no increase in short term mortality in high MELD patients. Contributing factors such as muscle mass, acute physiologic assessment and chronic health evaluation score, donor age, graft weight/recipient weight ratio, and inclusion of the middle hepatic vein in a right lobe graft influence morbidity and mortality in high MELD patients. Higher mortality is observed with pretransplant renal dysfunction, but short-term mortality is rare. Sarcopenia and recent infection are not contraindications to LDLT. Morbidity and prolonged LOS are common, and more frequent in patients with renal dysfunction, nutritional deficiency or recent infection.
CONCLUSIONS
When individual risk factors are studied mortality is low and graft loss is infrequent, but morbidity is common. MELD, especially with concomitant risk factors, had the greatest influence on short term outcome, and recent infection had the least. A multidisciplinary team of experts should carefully assess patients with multiple risk factors, and an optimal graft is recommended.

Review
Nephrotoxicity has been described in some patients with inflammatory bowel disease (IBD) treated with 5-aminosalicylic acid (5-ASA). Studies with 5-ASA treatment in which serum creatinine or creatinine clearance was measured regularly show that nephrotoxicity is exceptional (mean rate of only 0.26% per patient-year). There have been several case reports, including 46 patients, of renal disease associated with 5-ASA treatment in patients with IBD. 5-ASA treatment-related nephrotoxicity is reported most often within the first 12 months, but also delayed presentation after several years has been shown. The absence of a clear relationship between 5-ASA dose and the risk of nephrotoxicity suggests that this complication is idiosyncratic rather than dose-related. Most of the patients with renal disease associated with 5-ASA treatment suffered interstitial nephritis, with symptoms and signs being nonspecific, which may delay detection for many months. The nephrotoxicity potential of mesalazine and sulfasalazine seems to be similar. The risk with different oral preparations of 5-ASA is probably too small to influence the choice of agent. Mesalazine should be withdrawn when renal impairment manifests in a patient with IBD; if this does not result in a fall in serum creatinine, then renal biopsy should be considered. A trial of high-dose steroid may be recommended in patients whose renal function does not respond to drug withdrawal. The optimal monitoring schedule of serum creatinine in patients receiving 5-ASA treatment remains to be established, as there is no evidence to date that either the test, or the frequency of testing, improves patient outcomes.
