ABSTRACT

<p><b>OBJECTIVE</b>To explore the pathological and clinical characteristics of children with liver diseases by retrospective study on clinical and liver biopsy pathological data of children with liver diseases.</p><p><b>METHOD</b>This retrospective analysis was performed at Beijing No. 302 Hospital among 3 932 children with liver diseases who visited the hospital from January 2001 to December 2012. The kinds of diseases were compared with the results of 1983-2000.</p><p><b>RESULT</b>(1) Liver biopsy was successful in 99.72% (3 932/3 943) of cases of 2001-2012 group, complications occurred in 31 children only. (2) Of the 3 932 cases, 2 647 (67.32%) had hepatitis , non-hepatotropic viral hepatitis and non viral liver disease were seen in 365 cases (9.28%), and 920 cases (23.4%), respectively. Among 2 647 cases with viral hepatitis, 2 115 were hepatitis B (79.90%), 521 hepatitis C (19.69%), 7 were hepatitis A (0.26%) and 4 hepatitis E (0.15%), respectively. (3) In 2001-2012 group, the degrees of inflammatory activity (>G2) of liver were seen in 9.57% (202/2 111) patients with hepatitis B, while 23.57% (132/560) in 1983-2000 group. There was significant difference between the two groups (χ(2)=80.36, P=0.00 ). (4) Significant difference was observed in the rate of non viral liver disease between 2001-2012 group (23.40%, 920/3 932) and 1983-2000 group (9.61%, 98/1 020) (χ(2)=93.46, P=0.00). In 2001-2012 group, including 46 kinds of diseases, which were significantly higher than those of 1983-2000 group (18 kinds). In 2000-2012, the main causes of diseases were liver degeneration (18.26%, 168/920), drug-induced liver injury (13.59%, 125/920), fatty liver (8.80%, 81/920) and liver glycogen accumulation disease (8.70%, 80/920). While in 1983-2000 group, the main causes were liver degeneration (20.41%, 20/98), fatty liver (16.33%, 16/98), glycogen storage disease (10.20%, 10/98) and myopathy (9.18%, 9/98).</p><p><b>CONCLUSION</b>Liver biopsy in children is safe and feasible. Hepatitis B virus was ranked first in children with liver diseases in 2001-2012 group. The kinds of non viral hepatic disorders had changed and extended.</p>
