A study of blood ascorbic acid in leprosy.

S N Sinha, S C Gupta, A K Bajaj

    International Journal of Leprosy and Other Mycobacterial Diseases : Official Organ of the International Leprosy Association
    |June 1, 1984

    Summary

    Leprosy patients exhibit low blood ascorbic acid (vitamin C) levels, particularly in the tuberculoid form. Supplementing vitamin C alongside dapsone (DDS) therapy improved patient condition and accelerated ulcer healing.

    Area of Science:

    • Biochemistry
    • Dermatology
    • Nutritional Science

    Background:

    • Leprosy is associated with reduced blood ascorbic acid levels.
    • Ascorbic acid deficiency is more pronounced in the tuberculoid form of leprosy.
    • Dapsone (DDS) treatment does not appear to affect ascorbic acid levels.

    Purpose of the Study:

    • To investigate basal blood ascorbic acid levels in leprosy patients.
    • To evaluate the effect of ascorbic acid supplementation on leprosy complications and treatment.
    • To assess the role of ascorbic acid in lactate and pyruvate metabolism in leprosy.

    Main Methods:

    • Measured blood ascorbic acid levels in 70 leprosy patients.
    • Compared levels between leprosy types and treatment groups.

  • Assessed clinical improvement and biochemical markers (lactic and pyruvic acids) after ascorbic acid supplementation.

    • Main Results:

    • Significantly reduced ascorbic acid levels were observed in both lepromatous and tuberculoid leprosy.
    • Ascorbic acid supplementation improved healing of trophic ulcers and normalized elevated lactic and pyruvic acid levels.
    • Erythema nodosum leprosum (ENL) did not affect ascorbic acid levels in lepromatous leprosy.

    Conclusions:

    • Ascorbic acid deficiency in leprosy may stem from the disease itself or nutritional factors.
    • Ascorbic acid supplementation shows promise in improving leprosy patient outcomes and ulcer healing.
    • Ascorbic acid may play a role in managing metabolic disturbances associated with leprosy and DDS treatment.
