Recently, the Acute Kidney Injury Network (AKIN) defined acute renal failure as acute kidney injury (AKI) on the basis of an absolute increase in sCr of 0.3mg/dl or a percentage increase in sCr ≥ 50% providing also a staging from 1 to 3. AKIN stage 1 was defined as an increase in sCr ≥ 0.3mg/dl or increase in sCr ≥ 1.5-fold to 2-fold from baseline. AKI diagnosed with the two different criteria was evaluated for the prediction of in-hospital mortality.
METHODS: Consecutive hospitalized patients with cirrhosis and ascites were included in the study and evaluated for the development of AKI.
RESULTS: Conventional criterion was found to be more accurate than AKIN criteria in improving the prediction of in-hospital mortality in a model including age and Child-Turcotte-Pugh score. The addition of either progression of AKIN stage or a threshold value for sCr of 1.5mg/dl further improves the value of AKIN criteria in this model. More in detail, patients with AKIN stage 1 and sCr<1.5mg/dl had a lower mortality rate (p=0.03), a lower progression rate (p=0.01), and a higher improvement rate (p=0.025) than patients with AKIN stage 1 and sCr ≥ 1.5mg/dl.
CONCLUSIONS: Conventional criterion is more accurate than AKIN criteria in the prediction of in-hospital mortality in patients with cirrhosis and ascites. The addition of either the progression of AKIN stage or the cut-off of sCr ≥ 1.5mg/dl to the AKIN criteria improves their prognostic accuracy.
