Abstract
Background
Growth/differentiation factor-15 (GDF-15) plays a crucial role in modulating inflammation and fibrosis and is emerging as a potential biomarker in metabolic diseases. This study investigated the association between circulating GDF-15 levels and the development of diabetic kidney disease (DKD) in patients with type 2 diabetes mellitus (T2DM), with or without metabolic dysfunction-associated fatty liver disease (MAFLD).
Methods
In this prospective observational study, participants were stratified into three groups: those with T2DM and MAFLD (Group A) and those with T2DM and no MAFLD (Group B), alongside a healthy control group (Group C). Comprehensive clinical evaluations and laboratory assessments, including measurements of GDF-15, metabolic profiles, liver enzymes, and renal function, were performed.
Results
GDF-15 levels demonstrated a stepwise elevation from controls to T2DM patients, with the highest levels observed in patients with MAFLD (1929 ± 412 pg/mL in Group A, 1655 ± 368 pg/mL in Group B, and 1246 ± 245 pg/mL in Group C; p < 0.001). DKD was diagnosed in 51.4 % of patients in Group A compared to 37.1 % in Group B (p < 0.001). Multivariate analysis identified GDF-15 as the sole independent predictor of DKD (p = 0.01). ROC curve analysis revealed that a GDF-15 cutoff value of ≥1890.51 pg/mL provided an AUC of 0.951, with a sensitivity of 94.2 % and specificity of 87.1 %.
Conclusion
Elevated GDF-15 levels are independently associated with an increased risk of DKD in T2DM patients, particularly in those with MAFLD. These findings highlight the potential of GDF-15 as an early biomarker for DKD.
期刊介绍:
Journal of Diabetes and Its Complications (JDC) is a journal for health care practitioners and researchers, that publishes original research about the pathogenesis, diagnosis and management of diabetes mellitus and its complications. JDC also publishes articles on physiological and molecular aspects of glucose homeostasis.
The primary purpose of JDC is to act as a source of information usable by diabetes practitioners and researchers to increase their knowledge about mechanisms of diabetes and complications development, and promote better management of people with diabetes who are at risk for those complications.
Manuscripts submitted to JDC can report any aspect of basic, translational or clinical research as well as epidemiology. Topics can range broadly from early prediabetes to late-stage complicated diabetes. Topics relevant to basic/translational reports include pancreatic islet dysfunction and insulin resistance, altered adipose tissue function in diabetes, altered neuronal control of glucose homeostasis and mechanisms of drug action. Topics relevant to diabetic complications include diabetic retinopathy, neuropathy and nephropathy; peripheral vascular disease and coronary heart disease; gastrointestinal disorders, renal failure and impotence; and hypertension and hyperlipidemia.
