From the Guidelines

The diagnosis of acute kidney injury (AKI) should be based on the Kidney Disease Improving Global Outcomes (KDIGO) criteria, which define AKI as an increase in serum creatinine by 0.3 mg/dL within 48 hours or an increase in serum creatinine to 1.5-fold from baseline within 7 days. The KDIGO criteria also include urine output criteria, with a urine output of less than 0.5 mL/kg/h for 6 hours indicating AKI 1. The diagnosis of AKI is crucial in patients with cirrhosis, as it is associated with increased mortality and morbidity 1.

The KDIGO criteria have been widely adopted and are recommended by various guidelines, including the International Club of Ascites (ICA) and the American Gastroenterological Association (AGA) 1. The use of these criteria allows for early detection and management of AKI, which is essential in improving patient outcomes.

Some key points to consider when diagnosing AKI include:

  • The use of serum creatinine as a marker of renal function, with an increase in serum creatinine by 0.3 mg/dL within 48 hours or an increase in serum creatinine to 1.5-fold from baseline within 7 days indicating AKI
  • The importance of urine output in the diagnosis of AKI, with a urine output of less than 0.5 mL/kg/h for 6 hours indicating AKI
  • The need to consider other potential causes of kidney disease, such as chronic kidney disease (CKD) or hepatorenal syndrome (HRS)
  • The importance of early detection and management of AKI in improving patient outcomes.

Overall, the KDIGO criteria provide a standardized and widely accepted definition of AKI, and their use is essential in the diagnosis and management of AKI in patients with cirrhosis.

From the Research

Diagnosis Criteria for AKA (Diabetic Ketoacidosis)

  • The diagnosis of AKA (Diabetic Ketoacidosis) is confirmed when all three of the following criteria are present 2:
    • 'D': Elevated blood glucose levels or a family history of diabetes mellitus
    • 'K': The presence of high urinary or blood ketoacids
    • 'A': A high anion gap metabolic acidosis
  • Early diagnosis and management are crucial to improve patient outcomes 2
  • The mainstays of treatment include:
    • Restoration of circulating volume
    • Insulin therapy
    • Electrolyte replacement
    • Treatment of any underlying precipitating event 2
