Hyperuricemia as an independent risk factor for non-alcoholic fatty liver disease (NAFLD) progression evaluated using controlled attenuation parameter-transient elastography: Lesson learnt from tertiary referral center

Abstract Background and aim Hyperuricemia is one of the metabolic parameter which has been considered to play an important role in non-alcoholic fatty liver disease (NAFLD). However, there is still lack of studies about association between serum uric acid with liver disease progression in NAFLD. This study aimed to know the association between hyperuricemia with moderate to severe steatosis and significant fibrosis along with other metabolic factors in NAFLD patients evaluated using Controlled Attenuation Parameter (CAP) – Transient Elastography (TE). Methods This is a prospective study in NAFLD patients who came to our tertiary referral center University hospital hepatobiliary outpatient's clinic. All patients underwent metabolic parameters measurement including serum uric acid level and CAP-TE examination. Cutoff value used for significant liver fibrosis ≥7 kPa and ≥285 dB/m for moderate-severe steatosis. Results Of 113 NAFLD patients, there were 45 patients with moderate-severe steatosis and 34 patients with significant fibrosis. Multivariate analysis showed only high level of fasting blood glucose (OR 2756; 95% CI 1.131–6.717) and low HDL level (OR 4.196, 95% CI 1.22–14.430) to be independent risk factors of moderate-severe steatosis. High level of fasting blood glucose (OR 3.98, 95% CI 1.105–14.389) and hyperuricemia (OR 2.501, 95% CI 1.095–5.714) were found to be independent risk factors for significant liver fibrosis. Conclusion Hyperuricemia is found to be an independent risk factor for significant liver fibrosis.
