About

This is a phase IV, unicentric, open-label. Patients eligible for this study will be patients with AKI 1B or greater and decompensated cirrhosis from the hospital participating in the study

Full description

This is a phase IV, unicentric, open-label, randomized clinical trial to evaluate the efficacy of intravenous human albumin administration versus saline solution (NaCl 0.9%) in patients with decompensated cirrhosis and AKI 1B or grater.

Patients will be randomized to receive (1:1):

1. Intravenous Human Albumin 20% (20 g/100 ml), at a dose of 1 g per kg body weight with a maximum of 100 g per day, during 48 hours.
2. Saline solution (NaCl 0.9%) 500 ml every 24 hours, administered during 48 hours. Patients will be followed up for 28 days since the administration of the treatment (at baseline visit).

Enrollment: 114 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Age ≥ 18 years old.
2. Cirrhosis defined by standard clinical criteria, ultrasonographic findings and/or histology. (Cirrhosis of any etiology may be included).
3. Patients with AKI 1B or greater, defined according to EASL guidelines (EASL. J Hepatol 2018).
4. Women of child-bearing potential* must have a negative pregnancy test in serum before the inclusion in the study and agree to use highly effective contraceptive methods during the study. Highly effective contraceptive methods will include: intrauterine device, bilateral tubal occlusion, vasectomized partner and sexual abstinence** (only if refraining from heterosexual intercourse during the period of twelve months). Hormonal contraceptive methods will be avoided due to the risk of adverse events and impairment of liver function

Exclusion criteria

1. Time since AKI diagnosis > 24 hours.
2. Patients with AKI due to pure hypovolemia. According to guidelines, these patients should receive crystalloid solutions (i.e. NaCl 0.9%) and will be excluded from the study. Fluid losses will be specifically assessed by an accurate anamnesis and physical examination. If patient's diuretic treatment has been increased recently (within prior 2 weeks), or the patient had diarrhea before admission, patient will be considered that the AKI phenotype is pre-renal and will be excluded from the analysis. Patients will be excluded when clear evidence of hypovolemia is present, based on clinical history (e.g, recent fluid losses, diuretic escalation, diarrhea) and corroborating physical findings (e.g, dry mucous membranes, reduced skin turgor, sunken eyes, or low jugular venous pressure)
3. Patients with AKI due to gastrointestinal bleeding with AKI 1B or greater, and hemoglobin < 7.0 g/dL. These patients can be included after 48 hours without rebleeding and Hb ≥ 8.0 g/dL, and still present AKI 1B or greater.
4. Patients who had already received albumin at the time of inclusion/exclusion criteria assessment.
5. Patients with Chronic kidney disease grade 3a or higher, defined as glomerular filtration rate <60ml/min for three months and markers of kidney damage (one or more): Albuminuria (Albumin excretion rate > 30 mg/24h; Albumin-to-creatinine ratio > 30 mg/g), Urine sediment abnormalities, Electrolyte and other abnormalities due to tubular disorders, Abnormalities detected by histology or Structural abnormalities detected by imaging.
6. Patients under renal replacement therapy, or with urgent criteria of RRT.
7. Patients with hepatocellular carcinoma beyond Milan criteria.
8. Patients with severe extrahepatic comorbidities, including congestive heart failure New York Heart Association Grade III/IV, chronic obstructive pulmonary disease Global Initiative for Chronic Obstructive Lung Disease group 2 or higher.
9. Previous liver and/or kidney transplantation.
10. Patients with current extra hepatic malignancies including solid tumors and hematologic disorders.
11. Patients included in other clinical trials in the month before inclusion.
12. Patients with mental incapacity, language barrier, bad social support or any other reason considered by the investigator precluding adequate understanding, cooperation or compliance in the study.
13. Refusal to give informed consent.
