AI Article Synopsis
- The study examines the changes in serum levels of anti-aging protein Klotho and NGAL in type 2 diabetes patients across different stages of diabetic kidney disease (DKD), showing significant alterations compared to control subjects.
- Significant negative correlation between Klotho and NGAL levels was found, indicating potential involvement in DKD progression and associated inflammatory and metabolic processes.
- The research suggests that both Klotho and NGAL could serve as promising biomarkers for early diagnosis of DKD in individuals with type 2 diabetes.
Article Abstract
Objective: To investigate the changes of serum anti-aging protein Klotho and neutrophil gelatinase-associated lipocalin (NGAL) levels and their correlation in type 2 diabetes mellitus (T2DM) patients at different stages of diabetic kidney disease (DKD) determined by urinary albuminuria.
Methods: 462 cases with T2DM were divided into three groups: normoalbuminuric [N-UAlb; urinary albumin to creatinine ratio (UACR) < 30 mg/g, n=180], microalbuminuric [M-UAlb; UACR 30-300 mg/g, n = 158], macroalbuminuric [L-UAlb; UACR > 300 mg/g, n = 124]. The levels of serum soluble-Klotho (sKlotho), NGAL, 8-isoprostane prostaglandin F2α (8-iso-PGF2α), monocyte chemotactic protein-1 (MCP-1), tumor necrosis factor-α (TNF-α), transforming growth factor-β1 (TGF-β1) were determined by enzyme-linked immunosorbent assay (ELISA) in all cases and 160 control subjects.
Results: Compared with control, serum sKlotho levels were significantly decreased (P < 0.001), and serum NGAL levels increased significantly (P < 0.001) in T2DM patients. Furthermore, serum sKlotho and NGAL levels were significantly negatively correlated (P < 0.001). Serum sKlotho levels negatively correlated with UACR, TG, CHO, LDL, 8-Iso-PGF2α, MCP-1, TNF-α, TGF-β1 (P < 0.001), but positively correlated with LDL (P < 0.001). Serum NGAL levels positively correlated with UACR, 8-Iso-PGF2α, MCP-1, TNF-α, TGF-β1 (P < 0.001). In addition, serum NGAL levels and LDL were significantly positively correlated (P = 0.005), and HDL was significantly negatively correlated (P < 0.001).
Conclusion: Serum Klotho and NGAL levels may become new biomarkers of the early diagnosis of DKD in T2DM. Klotho may participate in the development of DKD pathological mechanism such as oxidative stress related to inflammation, renal fibrosis, lipid metabolic disorders, modulating the pathological process of diabetic kidney tissue. NGAL may play a part in these mechanisms.

Objective: Obesity is a major risk factor for osteoarthritis (OA). Adipose tissues may be linked to OA development through secretion of potential proinflammatory cytokines including neutrophil gelatinase-associated lipocalin (NGAL). Our objective was to assess changes in serum NGAL after a low-calorie diet (LCD) and subsequent glucagon-like peptide 1 receptor agonist (GLP-1 RA) treatment.

Background: Normothermic machine perfusion (NMP) provides a platform for kidney quality assessment. Donation after circulatory death (DCD) donor kidneys are associated with great ischemic injury and high intrarenal resistance (IRR). This experimental study aims to investigate the impact of different perfusion pressures on marginal kidney function and injury during NMP.

Introduction: Neutrophil gelatinase-associated lipocalin (NGAL) is believed to be involved in the pathogenesis of psoriasis, and its serum level was previously found to decline after administration of biologics, UV, and cyclosporine therapy.
Aim: To investigate whether NGAL may serve as a biomarker of disease activity in psoriasis vulgaris.
Material And Methods: To measure the level of NGAL in serum, 36 patients with psoriasis vulgaris and 33 healthy controls were enrolled.

Background: Cadmium (Cd) is a toxic heavy metal present in environment that has potential to instigate renal toxicity. Didymin (DDM) is a natural flavone, which shows anti-oxidant, anti-inflammatory and antiapoptotic nature. Therefore, the current study was formulated to appraise attenuative potential of DDM against Cd instigated nephrotoxicity.

Background: Ischemia-reperfusion injury (IRI) often results in renal impairment. While the presence of neutrophil extracellular traps (NETs) is consistently observed, their specific impact on IRI is not yet defined. Sivelestat sodium, an inhibitor of neutrophil elastase which is crucial for NET formation, may offer a therapeutic approach to renal IRI, warranting further research.
