Plasma Thrombospondin-1 in Etiology-Specific Associations with Proteinuria Events in Pediatric Chronic Kidney Disease
Year: 2025
Type: article
Study design: Observational Study
Abstract: Background: Thrombospondin-1 (TSP-1) is a matricellular protein involved in kidney fibrosis, potentially influencing the progression of proteinuria. However, its potential as a predictive biomarker for proteinuria events in children with chronic kidney disease (CKD), particularly across different etiological subgroups, such as congenital anomalies of the kidney and urinary tract (CAKUT) and non-CAKUT, has not been fully explored. Methods: In this prospective study of 60 children with CKD, we assessed baseline plasma TSP-1 and tracked proteinuria events over one year. Participants were stratified into CAKUT and non-CAKUT groups. Results: In total, 5 of 60 participants had proteinuria events. Plasma TSP-1 was significantly lower in patients with events (21.18 vs. 36.28 μg/mL, p = 0.0364). In multivariable analysis, TSP-1 lost significance overall but remained predictive in the non-CAKUT subgroup (AUC = 0.79, p = 0.064; OR = 0.93, p = 0.028). Conclusions: Plasma TSP-1 may serve as an etiology-specific biomarker for proteinuria events in pediatric CKD, particularly among non-CAKUT patients, and warrants further investigation for personalized risk assessment.
