Abstract
The natural history of pediatric nonalcoholic steatohepatitis is still unknown; however, there are differences between adult and pediatric presentation. Apoptosis may play an important role in pathophysiologic pathways involved in liver damage and progression. Our aim was to detect early apoptosis markers, activated caspase-3 and cleaved cytokeratin-18, in hepatocytes and to correlate their presence with clinical, serologic, and histologic characteristics in pediatric nonalcoholic steatohepatitis. Twenty-five pediatric nonalcoholic steatohepatitis liver biopsies were evaluated by immunohistochemistry for presence of activated caspase-3 and cleaved cytokeratin-18. Biopsy specimens were semiquantitatively graded for activity (steatosis, inflammation, and ballooning) and fibrosis. Records were reviewed for serum aspartate aminotransferase, alanine aminotransferase, cholesterol, triglycerides, and body mass index, which was elevated in 92% of cases. Serum aspartate aminotransferase and alanine aminotransferase were elevated in 32% and 68% of cases, respectively. Sixty percent of biopsies exhibited lobular steatosis grade 3, 84% lobular inflammatory activity grade 1, 72% ballooning grade 1, and 76% fibrosis stage 3. Cleaved cytokera...Continue Reading
