Bone-marrow in tuberculoid leprosy.

R V Koranne, R Singh, B Iyengar

    Leprosy in India
    |April 1, 1978
    PubMed
    Summary
    This summary is machine-generated.

    Bone marrow examination in tuberculoid leprosy patients showed normal cytology. No acid-fast bacilli were detected in bone marrow smears, suggesting limited bone marrow involvement in this leprosy form.

    Area of Science:

    • Medical Microbiology
    • Hematology
    • Immunology

    Background:

    • Leprosy, particularly the tuberculoid form, is a chronic infectious disease primarily affecting the skin and peripheral nerves.
    • Understanding the systemic involvement, including bone marrow, is crucial for comprehensive disease management.

    Purpose of the Study:

    • To investigate the involvement of bone marrow in patients with untreated tuberculoid leprosy.
    • To assess bone marrow cytology and the presence of acid-fast bacilli in these patients.

    Main Methods:

    • Bone marrow smears were prepared from 24 untreated patients with confirmed tuberculoid leprosy.
    • Bone marrow smears from 5 healthy individuals served as controls.
    • Cytological examination of smears was performed to assess cellularity and morphology.

  • Microscopic examination for the presence of acid-fast bacilli was conducted.

    • Main Results:

    • Bone marrow cytology in tuberculoid leprosy patients was essentially normal.
    • No acid-fast bacilli were identified in the bone marrow smears of any patient.
    • Control group also exhibited normal bone marrow cytology.

    Conclusions:

    • The study suggests that bone marrow involvement is minimal or absent in untreated tuberculoid leprosy.
    • Normal bone marrow cytology and absence of acid-fast bacilli indicate that tuberculoid leprosy may not significantly impact hematopoietic tissue.
