Insights
Acute kidney disease (AKD) is common in cirrhosis patients and significantly lowers survival rates. This condition can recur or progress to chronic kidney disease (CKD), increasing mortality.
Area of Science:
- Nephrology
- Hepatology
- Internal Medicine
Background:
- The 2012 KDIGO guidelines defined acute kidney injury (AKI), acute kidney disease (AKD), and chronic kidney disease (CKD).
- While AKI in cirrhosis is well-studied, AKD's epidemiology and outcomes remain largely unknown.
- This study addresses the gap in understanding AKD in patients with cirrhosis.
Purpose of the Study:
- To determine the prevalence of AKD in patients with cirrhosis.
- To evaluate the impact of AKD on the clinical course, complications, and survival of these patients.
Main Methods:
- A cohort of 272 consecutive patients with cirrhosis was enrolled.
- Clinical and laboratory data were collected at baseline.
- Patients were followed for outcomes including death, liver transplant, or end of study.
Main Results:
- 29.4% of patients developed AKD during follow-up.
- AKD was associated with a significantly lower 5-year survival rate (34.8% vs. 88.8%).
- Patients with AKD experienced higher rates of cirrhosis complications and hospitalizations.
Conclusions:
- AKD is a frequent complication in patients with cirrhosis.
- AKD can be reversible but is prone to recurrence and progression to CKD.
- AKD significantly worsens morbidity and mortality in cirrhosis patients.
Background & Aims:
In 2012, the KDIGO group proposed new definitions for acute kidney injury (AKI), acute kidney disease (AKD) and chronic kidney disease (CKD). According to the definition adapted by the International Club of Ascites, AKI has been extensively investigated in patients with cirrhosis. On the contrary, there are currently no data on the epidemiology and clinical outcomes associated with AKD. The aim of the study was to assess the prevalence and the impact of AKD on the clinical course and survival of patients with cirrhosis.
Methods:
A total of 272 consecutive patients with cirrhosis attending our outpatient clinic were included in the study. Clinical and laboratory data were collected at inclusion. Patients were followed-up until death, liver transplant or the end of follow-up.
Results:
During follow-up, 80 patients developed AKD (29.4%). Forty-two (52.5%) recovered from the first episode of AKD and 26 maintained a normal renal function up to the end of follow-up. Sixteen patients developed a second episode of AKD. Globally, 36 patients (45.0%) died with AKD. Finally, AKD progressed to CKD in 11 patients (13.8%). The 5-year survival rate was significantly lower in patients who developed AKD than in those who did not (34.8% vs. 88.8%, p <0.001). The 5-year rates of complications of cirrhosis and of hospitalizations were also higher in patients with AKD than in those without AKD.
Conclusions:
AKD is frequent in patients with cirrhosis. It can be reversible, but it may recur and progress to CKD. AKD has a very negative impact on morbidity and mortality in patients with cirrhosis.
Lay Summary:
Renal impairment has a very negative impact on patients with cirrhosis. Renal impairment seems to be characterized by a very dynamic course, which is defined according to renal function and length of the impairment as acute kidney injury, acute kidney disease and chronic kidney disease. The role of acute kidney disease is currently unknown. Our study shows for the first time that acute kidney disease is frequent in patients with cirrhosis and has a very negative impact on survival.
