The elusive task of biomarkers of renal injury
نویسندگان
چکیده
Neutrophil gelatinase-associated lipocalin (NGAL) is one of the most promising candidate biomarkers of renal injury, with expression in renal tissue increasing dramatically after ischemia-reperfusion injury but not in the case of pure pre-renal failure. In a recent issue of Critical Care, Di Somma and colleagues reported that NGAL could improve the classification of acute kidney injury compared with clinical assessment and showed that NGAL was associated with poor prognosis. NGAL may therefore carry different information than biomarkers of renal function. This study finally provides additional evidence for the highly complex relationship between renal function and renal injury.

Early Detection of Renal Dysfunction in β Thalassemia with Focus on Novel Biomarkers
Improved survival among transfusion dependent thalassemia patients in recent years has led to the manifestation of morbidities such as renal dysfunction. Renal injury is still an underestimated complication in β thalassemia major patients. Chronic anemia, iron overload due to repeated transfusion, and specific iron chelators are the main factors in pathogenesis of renal dysfunction in β thalass...
متن کاملThe role of hormones in renal disease and ischemia-reperfusion injury
The patients with renal diseases, especially end-stage renal disease (ESRD), are at high risk of developing cardiovascular disturbances. Some hormones such as brain natriuretic peptide appear to be important serum biomarkers in predicting cardiac death in ESRD patients. Renal diseases cause inflammation, anemia, uremic toxins, fluid overload, and electrolyte disturbance. Kidney transplantation ...

Objective(s): lupus nephritis (LN) is a severe form of systemic lupus erythematosus (SLE) with renal complications. Current diagnosis is based on invasive renal biopsy and serum antibodies and complement levels that are not specific enough. The current study aims to identify new biomarker candidates for non-invasive diagnosis of LN and explore the pathogenic mechanisms...
متن کاملDifferent Biomarkers of Acute kidney Injury in Cancer Patients
Acute Kidney Injury (AKI) occurs if the kidneys suddenly lose their ability to remove waste products. When the kidneys lose their ability to filter, dangerous levels of waste products can accumulate, which can upset the chemical composition of the blood and urine. Chemotherapy is one of the methods used to treat or temporarily reduce cancer by using certain medications. The main task of this tr...
متن کاملAssessment of acute kidney injury by urinary β2-MG and NAG in pediatric cancer patients prescribed with Cisplatin, Carboplatin, and Ifosfamide as the chemotherapeutic agents
Background: Acute kidney injury (AKI) is defined as a failure in renal function leading to insufficiency of fluid and electrolyte homeostasis. Thus, sensitive biomarkers of renal tubular injury are needed to detect AKI earlier. In this study, urinary beta 2-microglobulin (β2-MG) and urinary N-acetyl-β-D-glucosaminidase (NAG) were evaluated for AKI prognosis/diagnosis in pediatric patients suffe...
