BackgroundHepatorenal syndrome in cirrhosis with ascites is a well-defined entity with significant morbidity and mortality. It is unclear whether milder degrees of acute kidney injury (AKI), defined as a serum creatinine increase of over 26.4 μmol/l (0.3 mg/dl) or by 50% from baseline, also has a negative impact on patient outcomes.ObjectivesTo determine the prevalence of AKI in cirrhosis with ascites and the impact of AKI on patient outcomes.DesignPatients with cirrhosis with ascites and baseline serum creatinine less than 110 μmol/l, and no evidence of structural renal disease, prospectively underwent 4-6-weekly blood work-up for full blood count, biochemistry and liver function. Clinical assessments occurred every 4 months for the development of AKI and other complications.Results90 patients (mean age 55.8±0.8 years) with a mean follow-up of 14.05±1.07 months were enrolled. 82 episodes of AKI occurred in 49 patients, with the majority of episodes precipitated by a disturbance in systemic haemodynamics. The mean peak serum creatinine of the AKI episodes was within the laboratory's normal range. 73 episodes of AKI resolved; nine did not. There was no clear clinical predictor for the development or resolution of AKI. Despite resolution of most AKI episodes, a gradual and significant increase in serum creatinine and a gradual reduction in mean arterial pressure were observed during follow-up, associated with a significant reduction in survival compared with non-AKI patients.ConclusionMinor increases in serum creatinine are clinically relevant and can adversely affect survival. Every effort should be made to avoid precipitation of AKI in cirrhosis and ascites. |
