Changes in liver function were evaluated by changes in the Child Pugh Score at days 7, 30, and 90. The Child Pugh Score is a scoring system used to assess the severity of chronic liver disease. Scores range from 5 to 15, with higher scores indicating more severe disease. Points are assigned as follows:
Hepatic encephalopathy: None = 1 point, Grade 1 and 2 = 2 points, Grade 3 and 4 = 3 points Ascites: None = 1 point, mild = 2 points, moderate to severe = 3 points Total Bilirubin: under 2 mg/dl = 1 point, 2 to 3 mg/dl = 2 points, over 3 mg/dl = 3 points Albumin: greater than 3.5g/dl = 1 point, 2.8 to 3.5g/dl = 2 points, less than 2.8g/dl = 3 points International normalised ratio (INR): under 1.7 = 1 point, 1.7 to 2.3 = 2 points, above 2.3 = 3 points
Assigned points for each category are summed to calculate the Child Pugh Score.
