Cortisol status in different types of leprosy

Area of Science:

• Endocrinology
• Infectious Diseases
• Mycobacterial Infections

Background:

• Leprosy, a chronic infectious disease, can affect various bodily systems.
• Endocrine function, particularly the hypothalamic-pituitary-adrenal (HPA) axis, may be impacted by chronic illness and stress.
• Cortisol, a key stress hormone, plays a crucial role in metabolic and immune regulation.

Purpose of the Study:

• To investigate basal plasma cortisol levels in patients with different forms of leprosy.
• To assess the adrenal reserve in leprosy patients using the ACTH stimulation test.
• To explore potential links between leprosy, chronic stress, and adrenal function.

Main Methods:

• Measurement of basal plasma cortisol levels in 12 healthy controls and 60 leprosy patients.
• Administration of ACTH (Synacthen) stimulation test to assess adrenal response.
• Comparison of cortisol levels between different leprosy types and controls.

Main Results:

• Basal plasma cortisol levels were within normal limits for most leprosy patients.
• Significantly lower basal cortisol levels were observed in patients with multibacillary leprosy.
• All leprosy patient groups showed a significant increase in plasma cortisol after ACTH stimulation, indicating maintained adrenal reserve.

Conclusions:

• Multibacillary leprosy may be associated with adrenal exhaustion, potentially due to chronic stress.
• Despite potential basal cortisol abnormalities, the adrenal gland retains its reserve capacity in leprosy patients.
• These findings highlight the complex interplay between leprosy, stress, and endocrine function.
