Approximately 30% of adult-onset systemic lupus erythematosus (SLE) patients develop lupus nephritis (LN). The gold standard for LN detection involves renal biopsies, invasive procedures not suitable for routine disease monitoring. A urinary biomarker panel comprised of lipocalin-like prostaglandin D synthase (LPGDS), transferrin, alpha-1-acid glycoprotein (AGP-1), ceruloplasmin, monocyte chemoattractant protein 1 (MCP-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) has shown promise to predict LN and response to rituximab at baseline. Whether these proteins predict LN during longitudinal sampling, however, remained unknown. Here, we quantified aforementioned urinary proteins at baseline (N = 25), six and twelve months (N = 17 each) after rituximab treatment. Urine MCP-1 (at six and twelve months) and AGP-1 (at twelve months) levels varied between patients with active vs mildly active/inactive LN. Findings support the use of urinary proteins to detect active LN in ongoing disease monitoring in adult-onset SLE patients, but need to be validated in larger cohorts.

Background: Ursodeoxycholic acid (UDCA), traditionally recognized for its hepatoprotective effects, has also shown potential in protecting kidney injury. This study aimed to evaluate the protective effects of UDCA against sepsis-induced acute kidney injury (AKI) and to elucidate the underlying mechanisms.
Methods: Sixty male C57BL/6 N mice were utilized to establish a sepsis-induced AKI model through intravenous injection of lipopolysaccharides (LPS, 10 mg/kg).

Kidney stones, a common urological disease, may involve the brain-kidney axis in their formation, though the specific mechanism remains unclear. This study aimed to investigate the effects of blue light on relevant metabolic indicators and oxidative stress status in rats with kidney stones through the brain-kidney axis. A rat model of kidney stones was established by administering 1% ethylene glycol and 2% ammonium chloride.

Infections associated with urinary catheters are often caused by biofilms composed of various bacterial species that form on the catheters' surfaces. In this study, we investigated the intricate interplay between Escherichia coli and Enterococcus faecalis during biofilm formation on urinary catheter segments using a dual-species culture model. We analyzed biofilm formation and global proteomic profiles to understand how these bacteria interact and adapt within a shared environment.

In vitro models that can faithfully replicate critical aspects of kidney tubule function such as directional drug transport are in high demand in pharmacology and toxicology. Accordingly, development and validation of new models is underway. The objective of this study was to characterize physiologic and transport functions of various sources of human renal proximal tubule epithelial cells (RPTECs).

Background: Renal dysfunction is significantly associated with poor prognosis in patients with heart failure. However, the prognostic significance of proteinuria as a potential marker of an impaired glomerular filtration barrier in acute heart failure (AHF) remains unclear. We aimed to investigate the prognostic value of urinary protein/creatinine ratio (PCR) in patients with AHF.
