Diagnostic Criteria of Hepatorenal Syndrome (HRS)

Major criteria

  1. Low glomerular filtration rate, as indicated by serum creatinine greater than 1.5 mg/dl or 24-hour creatinine clearance lower than 40 ml/minute

  2. Absence of shock, ongoing bacterial infection, fluid losses and current treatment with nephrotoxic drugs

  3. No sustained improvement in renal function (decrease in serum creatinine to 1.5 mg/dl or less or increase in creatinine clearance to 40 ml/minute or more) following diuretic withdrawal and expansion of plasma volume with 1.5 l of a plasma expander

  4. Proteinuria lower than 500 mg/day and no ultrasonographic evidence of obstructive uropathy or parenchymal renal disease

Additional criteria

  1. Urine volume lower than 500 ml/day

  2. Urine sodium lower than 10 mEq/l

  3. Urine osmolality greater than plasma osmolality

  4. Urine red blood cells less than 50 per high-power field

  5. Serum sodium concentration lower than 130 mEq/l

All major criteria must be present for the diagnosis of hepatorenal syndrome. Additional criteria are not necessary for the diagnosis, but provide supportive evidence.

 

 

Clinical types of hepatorenal syndrome

  

Type I: Rapid and progressive impairment of renal function as defined by a doubling of the initial serum creatinine to a level higher than 2.5 mg/dl or a 50% reduction of the initial 24-hour creatinina clearance to a level lower than 20 ml/minute in less than 2 weeks

Type II: Impairment in renal function (serum creatinine 41.5 mg/dl) that does not meet the criteria of type I
