AI Article Synopsis
- The study aimed to establish standard reference values for serum and urinary nephrin levels during normal pregnancy and compare them with levels in patients who later developed preeclampsia (PE).
- Researchers enrolled 117 healthy pregnant women and tracked their nephrin levels through various stages of pregnancy and postpartum.
- Results showed that nephrin levels significantly increased in women who developed PE, indicating that these levels could serve as predictive markers for the condition before clinical symptoms appear.
Article Abstract
Purpose: The aim of this study was to evaluate serum and urinary nephrin levels of normal pregnancy to establish a standard reference value and to compare them with patients who subsequently developed preeclampsia (PE).
Materials And Methods: In this prospective study, 117 healthy singleton pregnancies were enrolled between 6 to 20 weeks of gestation at 2 participating medical centers during October 2010 to March 2012. Urine and serum samples were collected at the time of enrollment, each trimester, and at 4 to 6 weeks postpartum. Enzyme-linked immunosorbent assay for nephrin was performed and samples from patients who subsequently developed PE were compared to the normal patients.
Results: Of 117 patients initially enrolled, 99 patients delivered at the study centers and of those patients, 12 (12.1%) developed PE at a median gestational age of 34⁺⁴ weeks (range 29⁺⁵-36⁺⁶). In the normal patients (n=68), serum nephrin level decreased and urinary nephrin level increased during the latter of pregnancy. In 12 patients who subsequently developed PE, a significant rise in the 3rd trimester serum and urinary nephrin levels, compared to the controls, was observed (p<0.001), and this increase occurred 9 days prior to the onset of clinical disease.
Conclusion: As the onset of PE was preceded by the rise in the serum and urinary nephrin in comparison to normal pregnancy, serum and urinary nephrin may be a useful predictive marker of PE.

Phospholipase A2 receptor 1 (PLA2R1) exists important role in membranous nephropathy. In this study, we evaluate a PLA2R1 in a middle-aged rat model of renal function repair to further investigate the molecular mechanisms of membranous nephropathy. We analyzed the PLA2R1 knockout (KO) model and PLA2R1 knock in (KI) model in rats, extending the time to 85 weeks of age.

CKD is frequently diagnosed only after a significant progression. GFR is the most common indicator of kidney function but is limited in detecting early CKD cases and distinguishing glomerular, tubular, and global CKD. Aiming to provide a glomeruli specific biomarker assay, we developed a peptide immunoaffinity targeted mass spectrometry method for the quantitation of three podocyte specific proteins in human urine: nephrin, podocalyxin, and podocin.

Article Synopsis
- The study investigates the impact of preeclampsia (PE) on the fetal kidneys by comparing urinary biomarkers in infants born to mothers with and without PE.
- Sixty-eight mothers and their newborns provided urine samples, revealing that infants from the PE group had lower body lengths and significantly higher levels of protein and creatinine in their urine.
- The results indicate potential glomerular immaturity or impaired kidney function in infants of mothers with PE, as higher protein and nephrin levels correlated negatively with gestational age.

Diabetic nephropathy (DN) is the most common microvascular complication of diabetes mellitus and a major cause of end-stage renal disease. Isoferulic acid (IFA) is a phenolic compound that has strong antioxidant, anti-inflammatory, and hypoglycemic effects. Researches and our previous study showed the potential anti-diabetic capacity and anti- oxidative stress damage targeting podocytes of IFA.

Minimal Change Disease (MCD) is a predominant cause of idiopathic nephrotic syndrome in the pediatric population, yet presents significant clinical challenges due to its frequent relapses and steroid resistance. Despite its relatively benign histological appearance, MCD is characterized by severe proteinuria, hypoalbuminemia, and edema, which may affect patient outcomes. Current treatment strategies primarily rely on corticosteroids, which are effective in inducing remission but are associated with high relapse rates, steroid resistance, and numerous long-term side effects, underscoring the need for more targeted and effective therapeutic approaches.
