From: Prognosis of alcohol-associated lactic acidosis in critically ill patients: an 8-year study

Variable

Definition

Alcohol abuse

Uncontrolled alcohol drinking despite adverse consequences such as hepatic toxicity.

Hypoglycemic event

Plasma glucose <70 mg/dL with or without symptoms27.

Acute kidney injury

At least 1.5 times increase in baseline serum creatinine.

Chronic kidney disease

Baseline serum creatinine 1.5 mg/dL for men and 1.4 mg/dL for women.

Liver disease

The presence of liver cirrhosis or hepatitis. Cirrhosis is diagnosed according to clinical manifestations, laboratory results and image studies; and hepatitis is diagnosed using the evidence regarding abnormal hepatic biochemical and functional tests.

Sepsis

The presence of infection together with systemic manifestations of infection.

High MCV

MCV >100 fL (normal range of MCV: 80–100 fL).

Hyperammonemia

Serum ammonia level >32 μmol/L (normal range of ammonia level: 11–32 μmol/L).

Lactate clearance rate per hour

100% × [(peak blood lactate level - dynamic blood lactate level when blood lactate concentration <5 mmol/L)/(peak blood lactate level)]/(time interval by hours spent between the peak and dynamic blood lactate level).
