[Malabsorption caused by HBsAg-positive panareteritis nodosa]

W Dölle, W Wenig, H Schomerus

    Zeitschrift Fur Gastroenterologie
    |May 1, 1976
    PubMed
    Summary

    Hepatitis B-associated polyarteritis nodosa (PAN) can cause severe gastrointestinal issues, including malabsorption syndrome due to chronic ischemia. This case highlights the link between PAN, hepatitis, and gastrointestinal complications.

    Area of Science:

    • Gastroenterology
    • Hepatology
    • Vascular Medicine

    Background:

    • Polyarteritis nodosa (PAN) is a systemic vasculitis that can affect multiple organs.
    • Hepatitis B virus (HBV) infection is a known risk factor for PAN.
    • Gastrointestinal symptoms are common in patients with PAN.

    Observation:

    • A 36-year-old male with HBsAg-positive hepatitis presented with predominantly gastrointestinal symptoms.
    • Angiography revealed arterial microaneurysms and stenoses in the liver, kidneys, and small intestine.
    • Autopsy confirmed these vascular findings and revealed intestinal infarctions and bowel necrosis.

    Findings:

    • The patient exhibited a reactive hepatitis confirmed histologically.
    • Chronic ischemia resulting from vascular occlusions led to malabsorption syndrome.

  • Necrosis and ulcerations of the large bowel were observed.

    • Implications:

    • This case underscores the significant gastrointestinal manifestations of HBV-associated PAN.
    • Chronic ischemia and malabsorption may contribute to cachexia in PAN patients.
    • Early recognition and management of gastrointestinal complications are crucial in managing PAN.
