Clinical significance of liver function and autoantibodies in patients with acute or chronic drug-induced liver injury / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical significance of liver function and autoantibodies in patients with acute or chronic drug-induced liver injury.</p><p><b>METHODS</b>51 patients with drug-induced liver injury were divided into acute drug induced liver injury group and chronic drug induced liver injury group, liver function and autoantibodies were compared between these two groups.</p><p><b>RESULTS</b>There was no significant difference (P more than 0.05) in alanine aminotransferase [(412.1+/-387.5) U/L and (376.0+/-319.7) U/L], aspartate aminotransferase [(352.5+/-457.9) U/L and (198.8+/-142.7) U/L], total bilirubin [(109.7+/-104.80)micromol/L and(102.4+/-135.7)micromol/L], direct bilirubin [(66.4+/-73.3)micromol/L and (61.2+/-72.1)micromol/L], alkaline phosphatase [(133.4+/-50.1) U/L and (147.4+/-97.3) U/L], gamma-glutamyltransferase [(139.9+/-134.1) U/L and (180.6+/-227.9) U/L], and albumin [(41.3+/-4.9) g/L and (39.8+/-5.3)g/L] between these two groups, however, the level of globulin [(25.1+/-5.3) g/L and (28.6+/-5.1) g/L] was significantly different between these two groups (P less than 0.05). The titers of Anti-nuclear antibody (ANA) and smooth muscle antibody (SMA) were less than or equal to 1:320 in patients with acute drug induced liver injury. The titers of ANA, antimitochondrial antibody (AMA), and SMA were more than or equal to 1:320 in most of the patients with chronic drug induced liver injury.</p><p><b>CONCLUSION</b>Liver function has no value in the diagnosis of acute or chronic drug induced liver injury. High titer autoantibodies are found in patients with chronic drug induced liver injury.</p>
