Serum uric acid level in chronic liver disease and its correlation with Child–Pugh score in a tertiary care hospital from South India
Abstract
Background: Chronic liver disease (CLD) is one of the important causes of morbidity and mortality in our country, and since the damage to the liver is irreversible, we have to look for many severity markers or predictors for the prognosis of the patient. In this study, we have tried to correlate the level of serum uric acid (UA) with the severity of CLD presented as a Child–Pugh score. Methods: A cross-sectional observational study was conducted at Vijayanagar Institute of Medical Science (VIMS), Ballari, Karnataka, from October 2015 to June 2017 in the Department of General Medicine. Fifty patients diagnosed with CLD, aged between 18 and 65 years, of either gender, were enrolled in the study. Serum UA levels were measured, and liver function and coagulation parameters were assessed. A statistical analysis was performed to evaluate the association between serum UA levels, liver function test, and coagulation parameters. Results: In our study, the mean serum UA level was 6.52 mg/dl and was raised in patients with CLD in correlation to its severity. Alcoholic liver disease (ALD) was the most common etiology for CLD (80%) followed by hepatitis B (Hep B) virus infection (12%) and hepatitis C (Hep C) virus infection (6%). Serum UA levels increased as the Child–Turcotte–Pugh (CTP) score increased. The mean UA level in CTP class C was 8.29 mg/dl. Various parameters such as serum aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase, total bilirubin, international normalized ratio (INR), calcium, and albumin were significantly associated with serum UA levels in CLD patients. Conclusion: The correlation between rising blood UA levels and the Child–Pugh score shows that UA estimate may be a valid and affordable indicator for assessing the extent of liver cirrhosis in CLD.
