Changes induced in human liver by long-term anticonvulsant therapy. Functional and ultrastructural data

Area of Science:

• Hepatology
• Pharmacology
• Cell Biology

Background:

• Anticonvulsant medications are widely prescribed.
• Their long-term effects on liver cells require detailed investigation.
• Hepatic microsomal enzymes play a role in drug metabolism.

Purpose of the Study:

• To investigate the functional and morphological effects of anticonvulsant therapy on hepatocytes.
• To quantify structural changes in liver cells over time.
• To explore potential drug-induced cellular damage.

Main Methods:

• Functional assessment of hepatic microsomal NADPH cytochrome c reductase activity.
• Quantitative ultrastructural analysis of hepatocyte smooth membranes.
• Morphological examination for abnormal cytoplasmic formations.

Main Results:

• All subjects exhibited increased hepatic microsomal NADPH cytochrome c reductase activity.
• A significant increase in hepatocyte smooth membranes was observed, doubling within 20 days.
• Abnormal lipofuscin-related cytoplasmic formations were noted in 50% of subjects.

Conclusions:

• Anticonvulsant therapy induces significant enzymatic and structural alterations in hepatocytes.
• These drug-induced changes manifest early and may involve abnormal degradation product accumulation.
• Further research is needed to elucidate the precise mechanisms and clinical implications.
