Abstract

Background: Diabetic nephropathy represents the primary etiology of end-stage renal disease globally. Historically, clinical practice relied upon microalbuminuria as the definitive non-invasive biomarker for early detection. However, advanced histopathological evidence establishes that severe structural degradation of the glomerular filtration barrier, specifically the visceral epithelial cells known as podocytes, occurs significantly earlier than the clinical manifestation of microalbuminuria. Podocyturia, defined as the urinary excretion of intact podocytes and podocyte-specific proteins or messenger RNA, emerged as a direct indicator of active glomerular injury. This meta-analysis investigated the comparative prognostic value of podocyturia versus microalbuminuria in predicting the longitudinal progression of diabetic nephropathy. Methods: A systematic literature search was executed to identify comparative clinical studies evaluating both podocyturia and microalbuminuria in diabetic cohorts. Seven essential manuscripts met rigorous inclusion criteria. Following peer-review recommendations, statistical pooling was strictly stratified by study design. Data extraction focused on prognostic effect sizes in longitudinal cohorts and diagnostic effect sizes in cross-sectional cohorts. Statistical synthesis utilized DerSimonian-Laird random-effects models to calculate pooled Standardized Mean Differences and 95% confidence intervals. Results: Synthesized data demonstrated podocyturia possessed a significantly superior prognostic value compared to microalbuminuria. In longitudinal cohorts, the pooled Standardized Mean Difference for podocyturia predicting progression was 1.95 (95% CI: 1.50 to 2.40, p < 0.001), whereas microalbuminuria was 0.58 (95% CI: 0.25 to 0.91, p = 0.04). Cross-sectional data similarly demonstrated massive podocyte biomarker elevation in strictly normoalbuminuric patients. Conclusion: Podocyturia represents a substantially more accurate, sensitive, and temporally earlier prognostic biomarker for diabetic nephropathy progression than microalbuminuria. Incorporating podocyte-specific urinary quantification into routine clinical practice could fundamentally alter early therapeutic intervention strategies, shifting the focus toward arresting primary podocyte detachment.

Abstract

The aging network kidney causes Oxidative Stress (OS) and damages the kidney. Studies of aging kidneys keep going growing by developing sirtuin as an antiaging. Sirtuin 1 (SIRT1) is a protein implicated in several disorders including diabetes functions as an anti-aging protein. Decreased eGFR in the elderly caused by his height prevalence factor risk disease kidney at an older age. The study aims to study the correlation between oxidative stress, SIRT1 serum levels, and eGFR in the elderly.  The method used in this research is observational with the cross-sectional method. The sample in this study was the whole elderly who met the inclusion and exclusion criteria, totaling 30 people. Exclusion criteria are patients with glomerulonephritis, nephropathy obstruction, nephropathy sour veins, and obesity. All patients complied requirements asked to fill informed consent form. The inspection was carried out by urinalysis ultrasound kidney and assessing serum MDA levels which were found to be higher in this study. This study showed SIRT1 and eGFR levels decreased in the elderly. There was a negative correlation with moderate correlation strength between serum MDA levels and serum SIRT1 levels and a strong correlation between serum MDA levels and eGFR in the elderly. There was a positive correlation with a moderate correlation between serum SIRT1 levels and eGFR in the elderly. SIRT1 is suggested to be examined in elderly patients with decreased eGFR, even without comorbidity.
