Liver Function Tests in Tuberculoid Leprosy

Area of Science:

• Hepatology
• Infectious Diseases
• Immunology

Background:

• Leprosy, particularly tuberculoid leprosy, can affect various organs.
• Previous studies indicated significant liver involvement in 85% of these patients.
• Understanding subclinical liver impact is crucial for comprehensive patient management.

Purpose of the Study:

• To evaluate liver function in patients with untreated tuberculoid leprosy.
• To correlate clinical observations of liver involvement with biochemical liver function tests.
• To determine if standard liver function tests can detect minimal hepatic changes in leprosy.

Main Methods:

• Study included 24 patients with untreated tuberculoid leprosy.
• Five healthy individuals served as controls.
• Standard liver function tests were performed, including prothrombin time, serum bilirubin, zinc sulphate turbidity, serum proteins, and serum transaminases.

Main Results:

• No statistically significant alterations were observed in the liver function tests of leprosy patients compared to controls.
• Despite prior histological evidence of liver involvement, biochemical tests did not reflect these changes.
• This suggests that minimal and focal hepatic changes may not be detectable by conventional liver function assays.

Conclusions:

• Standard liver function tests are not sensitive enough to detect minimal, focal liver involvement in tuberculoid leprosy.
• Further research may be needed to identify more sensitive biomarkers for subclinical liver disease in leprosy patients.
• Clinical management should consider potential subclinical organ involvement even with normal biochemical test results.
