Early Detection of Liver Damage in Mexican Patients with Chronic Liver Disease.

BACKGROUND AND

OBJECTIVE

Liver cirrhosis is usually detected at the later stages of disease. This study is aimed to detect liver damage in patients with chronic liver disease using transitional elastography (TE) and to assess the biochemical parameters associated with liver damage.

METHODS

In 578 patients, chronic liver disease based on etiology was diagnosed by clinical and laboratory tests. Liver damage was evaluated with TE (FibroScan®), while its association with biochemical parameters was performed using the logistic regression tests.

RESULTS

Overall, the main etiologies of liver damage were hepatitis C virus (HCV) (37%), alcoholic liver disease (ALD) (33%) and non-alcoholic steatohepatitis (NASH) (26%). Patients were 40 to 50 years of age. ALD and hepatitis B prevailed in men, whereas HCV and NASH in women. The stages of fibrosis were F0 (n = 121, 21%), F1 (n = 122, 21%), F2 (n = 58, 10%), F3 (n = 46, 8%) and F4 (n = 87, 15%). In patients with liver cirrhosis, ALD (n = 96/217, 45%), HCV (n = 94/217, 43%) and NASH (n = 21/217, 10%) were the leading etiologies. Platelets count (OR=3.31, 95%CI 1.61-6.78), glucose (OR=3.07, 95%CI 1.50-6.26), gamma-glutamyl-transferase (OR=3.60, 95%CI 1.79-7.25), albumin (OR=3.89, 95%CI 1.61-9.36), and total bilirubin (OR=3.93, 95%CI 1.41-10.91) were associated to advanced stages of fibrosis (F3-F4) regardless of etiology. The concordance and positive predictive values of these parameters were higher as compared to other scores.

CONCLUSION

Asymptomatic liver disease due to HCV, ALD and NASH prevailed in young adults. Advanced liver damage assessed by TE was associated with five biochemical parameters. In conjunction, both methodologies may be useful for the early detection of fibrosis and cirrhosis in Latin America.
