    Area of Science:

    • Hepatology
    • Cell Biology
    • Biochemistry

    Context:

    • Investigates Wilson-Konovalov disease (hepatolenticular degeneration) in 18 patients.
    • Focuses on liver-related symptoms and electron microscopic findings.
    • Examines mitochondrial and lipid metabolism in hepatic cells.

    Purpose:

    • To elucidate the pathogenetic mechanisms underlying Wilson-Konovalov disease.
    • To correlate clinical manifestations with ultrastructural hepatic changes.
    • To evaluate the long-term efficacy of d-penicillamine treatment.

    Summary:

    • Electron microscopy revealed mitochondrial dysfunction, suggesting impaired hepatocyte energy metabolism.
    • Observed lipid accumulations (neutral and phospholipids) indicate disrupted lipid metabolism involving lysosomes.
    • The term "Wilson-Konovalov cirrhosis" is justified in patients with predominant liver symptoms.
    • Pathogenetic treatment with d-penicillamine demonstrated significant clinical improvement and better long-term prognosis.

    Impact:

    • Highlights the role of mitochondrial and lipid metabolism defects in Wilson-Konovalov disease.
    • Provides evidence for the therapeutic benefits of d-penicillamine in managing the disease.
    • Contributes to understanding the cellular basis of liver pathology in Wilson-Konovalov disease.
