Adrenocortical hormones and interleukin patterns in leprosy

Area of Science:

• Endocrinology
• Immunology
• Infectious Diseases

Background:

• Leprosy presents distinct clinical forms, lepromatous (LL/BL) and tuberculoid.
• Adrenocortical hormones and inflammatory cytokines play roles in disease pathology.

Purpose of the Study:

• To investigate adrenocortical hormone status in leprosy.
• To explore the relationship between hormone levels and inflammatory cytokines.

Main Methods:

• Measured plasma levels of Interleukin (IL)-1beta, IL-6, tumour necrosis factor (TNF)-alpha, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), adrenocorticotropic hormone, cortisol, and dehydroepiandrosterone sulfate (DHEA-S).
• Compared levels between leprosy patients (LL/BL) and healthy controls.
• Analyzed correlations between inflammatory markers and hormone levels.

Main Results:

• LL/BL leprosy patients exhibited significantly higher IL-1beta, IL-6, TNF-alpha, CRP, and ESR compared to controls.
• Positive correlations were found between IL-6/TNF-alpha and ESR/CRP.
• Adrenocorticotropic hormone and cortisol levels were similar between groups.
• Dehydroepiandrosterone sulfate (DHEA-S) levels were significantly lower in leprosy patients.
• Inverse correlations were observed between DHEA-S and IL-6, TNF-alpha, and CRP.

Conclusions:

• Leprosy is associated with a pro-inflammatory state and altered adrenal androgen levels.
• Lower DHEA-S may be linked to increased inflammation in leprosy.
• These findings suggest a potential pathogenetic role for DHEA-S in leprosy and other inflammatory conditions.
