Lipophagy and Mitophagy in Renal Pathophysiology.

The lysosomal autophagic pathway plays a fundamental role in cellular and tissue homeostasis, and its deregulation is linked to human pathologies including kidney diseases. Autophagy can randomly degrade cytoplasmic components in a nonselective manner commonly referred to as bulk autophagy. In contrast, selective forms of autophagy specifically target cytoplasmic structures such as organelles and protein aggregates, thereby being important for cellular quality control and organelle homeostasis. Research during the past decades has begun to elucidate the role of selective autophagy in kidney physiology and kidney diseases. In this review, we will summarize the knowledge on lipophagy and mitophagy, two forms of selective autophagy important in renal epithelium homeostasis, and discuss how their deregulations contribute to renal disease progression.

Impact of Renin-Angiotensin System Blockade on Mortality and Allograft Loss among Renal Transplant Recipients: A Systematic Review and Meta-Analysis.

The blockade of the renin-angiotensin system (RAS) has a beneficial effect on reducing the levels of proteinuria and blood pressure in patients with chronic kidney disease (CKD) and reduces the risk of developing end-stage kidney disease in CKD patients. Nonetheless, a debate persists regarding the impact of RAS inhibitors on outcomes such as mortality and graft survival in renal transplant patients. To assess the effect of RAS inhibitors on graft recipients in the past decade, we conducted a systematic review and meta-analysis. We searched Embase, PubMed, and the Cochrane Central Register of Clinical Trials from January 1, 2012, to August 1, 2022. We included 14 articles, comprising 5 randomized controlled trials (RCTs) and 9 cohort studies, including 45,377 patients. These studies compared patient or graft survival between an RAS inhibitor treatment arm and a control arm. The meta-analysis revealed that RAS blockade was significantly associated with lower mortality in cohort studies (risk ratio [RR] = 0.66, 95% confidence interval [CI]: 0.55-0.79), reduced allograft loss in cohort studies (RR = 0.62, 95% CI: 0.54-0.71), and significant changes in systolic blood pressure in RCTs. Subgroup analysis of the groups of interest (interventions involving RAS blockade, follow-up period of ≥5 years) showed consistently reduced mortality (RR = 0.67, 95% CI: 0.56-0.81) and reduced allograft loss (RR = 0.61, 95% CI: 0.54-0.70). Our results demonstrated that the application of RAS blockade among renal transplant recipients was associated with lower mortality and allograft loss in cohort studies but not in RCTs. More powered clinical trials are needed to evaluate the effects of RAS blockade in renal transplant recipients.

Magnesium Derangement among Critically Ill Patients with Acute Kidney Injury: An Association with Acute Kidney Disease.

The association between magnesium level and progression to acute kidney disease (AKD) in acute kidney injury (AKI) patients was not well studied. With AKI transition to AKD, the burden of the disease on mortality, morbidity, and healthcare costs increases. Serum magnesium disturbances are linked with a decline in renal function and increased risk of death in CKD and hemodialysis patients. This study aims to assess the significance of magnesium derangements as a risk factor for the progression of AKI to AKD in critically ill patients. This study was conducted among patients with AKI admitted to the intensive care units at Mayo Clinic from 2007 to 2017. Serum magnesium at AKI onset was categorized into five groups of <1.7, 1.7-1.9, 1.9-2.1, 2.1-2.3, and ≥2.3 mg/dL, with 1.9-2.1 mg/dL as the reference group. AKD was defined as AKI that persisted >7 days following the AKI onset. Logistic regression was used to evaluate the association between magnesium and AKD. Among 20,198 critically ill patients with AKI, the mean age was 66 ± 16 years, and 57% were male. The mean serum magnesium at AKI onset was 1.9 ± 0.4 mg/dL. The overall incidence of AKD was 31.4%. The association between serum magnesium and AKD followed a U-shaped pattern. In multivariable analysis, serum magnesium levels were associated with increased risk of AKD with the odds ratio of 1.17 (95% CI: 1.07-1.29), 1.13 (95% CI: 1.01-1.26), and 1.65 (95% CI: 1.48-1.84) when magnesium levels were <1.7, 2.1-2.3, and ≥2.3 mg/dL, respectively. Among patients with AKI, magnesium level derangement was an independent risk for AKD in critically ill AKI patients. Monitoring serum magnesium and proper correction in critically ill patients with AKI should be considered an AKD preventive intervention in future trials.
