Hepatic structure and function in Papua New Guineans with leprosy
Summary
Leprosy patients generally have normal liver function. Abnormal liver function in leprosy is usually due to other conditions like amyloidosis or sepsis, not the disease itself.
Area of Science:
- Hepatology
- Infectious Diseases
- Immunology
Background:
- Leprosy, a chronic infectious disease, can affect various organs.
- Hepatic involvement in leprosy requires further investigation to differentiate disease-specific effects from complications.
Purpose of the Study:
- To assess hepatic function and liver histology in patients with leprosy.
- To determine if leprosy itself impairs liver function or if complications are responsible.
Main Methods:
- Studied plasma bromsulphthalein (BSP) clearance and liver biopsy histology in 20 leprosy patients (lepromatous and tuberculoid/borderline) and 12 controls.
- Correlated abnormal BSP results with complicating factors such as hepatic amyloidosis, erythema nodosum leprosum (ENL), and malignancy.
Main Results:
- Most leprosy patients exhibited normal hepatic function (BSP clearance).
- Abnormal BSP results were associated with complicating factors like hepatic amyloidosis, ENL, hepatocellular carcinoma, and abscesses.
- Liver biopsies revealed vacuolated phagocytes, histiocytes, and tuberculoid granulomata; no cirrhosis was observed.
Conclusions:
- Leprosy is not inherently associated with impaired hepatocellular function.
- Abnormal liver function in leprosy patients typically indicates a concurrent severe complication or unrelated disease.
- Therapeutic agents in this study did not show association with abnormal liver structure or function.
