Purpose Of This Review: The purpose of this review is to explain the rationale and limitations for use of mineralocorticoid receptor blockers (MRBs) for the treatment of chronic kidney disease (CKD) and its complications.
Recent Findings: Recent studies in animal models of CKD demonstrate that blockade of the mineralocorticoid receptor using spironolactone or eplerenone decreases inflammation, oxidative stress, proteinuria and glomerular and tubular injury. Patients with CKD are at very high risk for progression of kidney disease and major cardiovascular events. Recent studies in patients with CKD demonstrate that administration of low doses of MRBs added onto an angiotensin-converting enzyme inhibitor-based regimen reduces proteinuria--a risk marker for both progressive kidney disease and cardiovascular events. However, incident hyperkalemia, an unwanted side effect, dampened enthusiasm for this approach. There are no large-scale, long-term outcome trials examining whether MRB can slow progression of kidney disease or prevent cardiovascular events.
Summary: At this time it is unknown whether mineralocorticoid receptor blockade can improve outcomes in patients with CKD. To move this field forward and determine whether these agents can improve the lives of patients with kidney disease, novel strategies to prevent or ameliorate hyperkalemia are needed.

Incidence and Risk Factors for Amiodarone-Induced Thyroid Dysfunction: A Nationwide Retrospective Cohort Study.
Am J Cardiovasc Drugs
January 2025
Division of Cardiology, Department of Internal Medicine, Ilsan Paik Hospital, Inje University College of Medicine, Goyang, Republic of Korea.
Background: Amiodarone is an effective anti-arrhythmic drug; however, it is frequently associated with thyroid dysfunction. The aim of this study was to investigate the incidence and risk factor of amiodarone-induced dysfunction in an iodine-sufficient area.
Methods: This retrospective cohort study included 27,023 consecutive patients treated with amiodarone for arrhythmia, using the Korean National Health Insurance database.
Improving Understanding of Fexofenadine Pharmacokinetics to Assess Pgp Phenotypic Activity in Older Adult Patients Using Population Pharmacokinetic Modeling.
Clin Pharmacokinet
January 2025
Clinical Pharmacology and Toxicology Service, Anesthesiology, Pharmacology and Intensive Care Department, Geneva University Hospitals, 4 Rue Gabrielle Perret-Gentil, 1205, Geneva, Switzerland.
Background And Objective: Fexofenadine is commonly used as a probe substrate to assess P-glycoprotein (Pgp) activity. While its use in healthy volunteers is well documented, data in older adult and polymorbid patients are lacking. Age- and disease-related physiological changes are expected to affect the pharmacokinetics of fexofenadine.

Department of Paediatrics, University Medical Centre Maribor, Ljubljanska ulica 5, 2000, Maribor, Slovenia.
Background: Serum and urinary uromodulin are emerging as potential cardiovascular risk factors. The aim of our study was to determine uromodulin in both serum and urine to evaluate their potential as early cardiovascular risk markers and markers of kidney function in children and young adults.
Methods: This case-control study included 72 participants - 42 children and young adults with chronic kidney disease stages 1-2 and 30 healthy controls.
Transcription factor MAZ activates the transcription of hypomethylated TYMP in ccRCC.

School of Medical Technology, Tianjin Medical University, Tianjin, 300203, China.
Clear cell renal cell carcinoma (ccRCC) is a highly malignant tumor characterized by a significant propensity for recurrence and metastasis. DNA methylation has emerged as a critical epigenetic mechanism with substantial utility in cancer diagnosis. In this study, multi-omics data were utilized to investigate the target genes regulated by the transcription factor MYC-associated zinc finger protein (MAZ) in ccRCC, leading to the identification of thymidine phosphorylase (TYMP) as a gene with notably elevated expression in ccRCC.

Background: Chronic inflammation is well recognized as a key factor related to renal function deterioration in patients with diabetic kidney disease (DKD). Neutrophil extracellular traps (NETs) play an important role in amplifying inflammation. With respect to NET-related genes, the aim of this study was to explore the mechanism of DKD progression and therefore identify potential intervention targets.
