Acute kidney injury (AKI) is a medical condition characterized by the sudden and severe decrease in kidney function. It can be caused by a variety of underlying medical conditions, such as sepsis, dehydration, toxin exposure, and certain medications.
AKI can manifest with a variety of clinical symptoms, including:
Severe fluid retention
Increased blood pressure
Increased heart rate
Nausea and vomiting
Headache
Dizziness and confusion
Loss of consciousness
The underlying causes of AKI can be more serious and can include:
Sepsis
Severe dehydration
Toxic insults to the kidneys
Certain medications
Underlying medical conditions such as diabetes, hypertension, and coronary artery disease
The diagnosis of AKI is based on a combination of clinical presentation and laboratory findings. A urine albumin-to-creatinine ratio (UACR) is the most commonly used laboratory test to diagnose AKI. A UACR of 30 mg/dL or higher indicates that there is albumin in the urine, which can be a sign of kidney damage.
Treatment for AKI depends on the underlying cause. Treatment may include:
Fluid replacement
Diuretics to remove excess fluid from the body
Antibiotics to treat sepsis
Medications to treat underlying conditions such as diabetes and hypertension
Dialysis for severe cases of AKI
Acute kidney injury can be a serious condition, but it is often preventable with proper medical care and lifestyle interventions
