Kidney diseases represent a global public health problem due to the aging of the population, the increasing prevalence of diabetes, hypertension, obesity and immune disorders. TNF-superfamily ligands are heterotrimeric transmembrane proteins with a molecular structure characterized by the presence of a TNF homology domain that binds to cysteine-rich regions of specific TNF-superfamily receptors. The tumor necrosis factor (TNF) superfamily consists of ligands and receptors that modulate adaptive immunity regulation, hematopoiesis, morphogenesis, as well as different disease states, including cancer and diabetes. DcR3 is found increased in a variety of cancer cells and various inflammatory tissues and is considered a potential biomarker to predict inflammatory disease progression and cancer metastasis. While increasing DcR3 expression may be possible to treat inflammatory diseases and enhance tissue repair, decreasing DcR3 expression may increase tumor apoptosis and suppress tumor growth in vivo. The study will be carried out with the prospective examination of patients without anuria and who developed Acute Kidney Injury or on the basis of Acute Kidney Disease on Chronic Kidney Disease. Sixty patients and 30 age- and gender matched control healthy individuals that accept enrollment in the study will be followed up by the Nephrology Department in Kırıkkale University Faculty of Medicine for 2 years. The aim of this study was to investigate the relationship between blood and urine DcR 3 levels on the effects of renal and patient prognosis in patients with Acute Kidney Injury as a predictor or an auxiliary test in prediction.
