Impact of body mass index on adverse kidney events in diabetes mellitus patients: A systematic-review and meta-analysis.

Background: The incidence of chronic kidney disease among patients with diabetes mellitus (DM) remains a global concern. Long-term obesity is known to possibly influence the development of type 2 diabetes mellitus. However, no previous meta-analysis has assessed the effects of body mass index (BMI) on adverse kidney events in patients with DM.

Decoy receptor 2 mediation of the senescent phenotype of tubular cells by interacting with peroxiredoxin 1 presents a novel mechanism of renal fibrosis in diabetic nephropathy.

Premature senescence of renal tubular epithelial cell (RTEC), which is involved in kidney fibrosis, is a key event in the progression of diabetic nephropathy. However, the underlying mechanism remains unclear. Here we investigated the role and mechanism of decoy receptor 2 (DcR2) in kidney fibrosis and the senescent phenotype of RTEC.

High-dose HOOK effect in urinary DcR2 assay in patients with chronic kidney disease.

Background: Urinary DcR2 (uDcR2) is a biomarker for the early detection the tubulointerstitial injury (TII) in patients with chronic kidney disease (CKD), but the high-dose hook effect may lead to falsely low or even negative results when using an enzyme-linked immunosorbent assay (ELISA). This study aimed to investigate if the high-dose hook effect exists with ELISA testing, and to uncover a potential approach for reducing this effect.

Methods: 72 CKD patients were recruited and categorized into four groups based on TII scores.

Urinary DcR2 is a novel biomarker for tubulointerstitial injury in patients with diabetic nephropathy.

Tubulointerstitial injury (TII) plays a crucial role in the progression of diabetic nephropathy (DN), but lack of specific and sensitive biomarkers for monitoring TII in DN management. This study is to investigate whether urinary decoy receptor 2 (uDcR2) could serve as a novel noninvasive biomarker for assessing TII in DN. We recruited 311 type 2 diabetics and 139 DN patients who were diagnosed by renal biopsy.
