Acute Kidney Injury
Conditions
Brief summary
The goal of this observational study is to assess the clinical value of humanin in acute kidney injury. The main questions it aims to answer are:whether Humanin can be a novel marker for predicting AKI Researchers will compare humanin concentration in healthy people to see if humanin can be a novel marker for predicting AKI
Detailed description
Acute Kidney Injury (AKI) is a clinically critical condition manifested by a sharp decline in kidney function, with approximately 13.3 million people diagnosed with AKI each year in hospital worldwide and associated with 1.7 million deaths. According to global multi-center research data, the total incidence of AKI in hospital is as high as 21%, and the incidence of acute kidney injury in hospitalized patients in China is 0.99%\ 11.6%. AKI increases the risk of long-term chronic kidney disease (CKD) and end-stage renal disease (ESRD), and has a very high long-term mortality rate. The diagnosis of AKI is mainly based on blood creatinine or urine output, and the current KDIGO criteria are used, but blood creatinine is a very insensitive indicator, so in the past 20 years, scholars have been exploring biological markers that are more sensitive than blood creatinine and urine output. Humanin is a mitochondrial polypeptide containing 24 amino acids. It was first identified in Alzheimer's disease patients in 2001. Studies have shown that Humanin has a strong mitochondrial protective effect in neurodegenerative diseases, cardiovascular diseases, diabetes, male infertility, cancer and other diseases, and its mechanism may be related to anti-apoptosis, anti-inflammation, regulation of autophagy and maintenance of mitochondrial homeostasis, because Humanin can function through autocrine, paracrine or endocrine forms, so it can be detected in the blood. Studies have shown that Humanin expression in serum or plasma of patients with diabetes and coronary heart disease is declined. In our previous study, the investigators found that Humanin was elevated in plasma in a mouse model of AKI with sepsis. The goal of this observational study is to assess the clinical value of humanin in acute kidney injury. The main questions it aims to answer are:whether Humanin can be a novel marker for predicting AKI
