About

Kidney dysfunction is a complex and common event in patients with liver cirrhosis. Although novel treatments have shown some promising results , acute kidney injury remains a major complication of decompensated liver cirrhosis with high morbidity and mortality rates . AKI occurs in up to 19-20% of hospitalized patients with liver cirrhosis and among the most frequent causes are prerenal azotemia (PRA), hepatorenal syndrome and acute tubular necrosis , with prevalence rates estimated around 68%, 25%, and 33%, respectively.

The introduction and widespread use of diagnostic criteria of AKI in the area of cirrhosis has contributed to an increased awareness and earlier detection of AKI. However, some important problems remain. One of the main issues is the differential diagnosis of AKI, particularly between acute tubular necrosis (ATN) and hepatorenal syndrome (HRS-AKI). This is important because treatment is different; renal replacement therapy (RRT) is used for the former, and vasoconstrictors and albumin are used for the latter.

Full description

Aim of the study:

To determine utility of NGAL in chronic liver disease patients with acute kidney injury.

Objective:

1. To compare urine NGAL values in HRS and Non-HRS group.
2. To determine optimal cutoff of urine NGAL for early determination of HRS.

Plan of investigation:

All the following investigations will be done at admission for the patients who satisfy the inclusion criteria

Routine blood investigations :

CBP, LFT, PT- INR, RFT urine sodium on day 1 urine spot urine protein creatinine ratio CUE Urine c/s Urine NGAL Serum creatinine will be repeated on Day 3.

Enrollment: 120 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
