Electrophoretic pattern of proteins in lepromatous leprosy

Area of Science:

• Clinical immunology
• Infectious diseases
• Biochemistry

Background:

• Leprosy, particularly lepromatous leprosy, is a chronic infectious disease caused by Mycobacterium leprae.
• Lepra reaction represents a complication of leprosy, involving immune-mediated inflammatory responses.
• Alterations in serum protein profiles are often observed in chronic inflammatory and infectious conditions.

Purpose of the Study:

• To investigate the changes in serum total proteins and their fractions in patients with lepromatous leprosy.
• To analyze the impact of lepra reaction on serum protein composition.
• To correlate these biochemical findings with the disease status.

Main Methods:

• Serum samples were collected from 50 patients with lepromatous leprosy and 11 patients with lepra reaction.
• Serum total proteins and protein fractions (albumin, globulins - alpha-1, alpha-2, beta, gamma) were analyzed.
• Comparison was made with healthy control subjects.

Main Results:

• Significant increase in serum total proteins observed in both lepromatous leprosy (14.5%) and lepra reaction (22.95%) groups.
• Elevated globulin fractions (alpha-1, alpha-2, and gamma) and decreased albumin, leading to a reversed albumin/globulin ratio.
• An additional globulin fraction was noted in 17 lepromatous leprosy and 2 lepra reaction cases.

Conclusions:

• Lepromatous leprosy and lepra reactions are associated with significant alterations in serum protein profiles.
• The observed changes, including increased total proteins and reversed A/G ratio, reflect the inflammatory and immune responses in leprosy.
• Further research into the additional globulin fraction may provide insights into disease pathogenesis.
