Bone morphometry in alcoholics

O Johnell, B E Nilsson, P E Wiklund

    Clinical Orthopaedics and Related Research
    |May 1, 1982
    PubMed
    Summary

    Alcoholism significantly increases osteoclast activity, leading to bone resorption. While not causing advanced osteomalacia, these changes impact bone health in men, particularly those with a history of gastric resection.

    Area of Science:

    • Bone Biology
    • Endocrinology
    • Nutritional Science

    Background:

    • Alcoholism is a chronic condition associated with numerous health complications.
    • Skeletal integrity can be compromised by long-term alcohol abuse.
    • Previous research suggests potential links between alcoholism and altered bone metabolism.

    Purpose of the Study:

    • To investigate the effects of alcoholism on bone turnover in men.
    • To compare osteoclast activity and osteoid abundance in alcoholics versus controls.
    • To explore if prior gastric resection influences alcohol-related bone changes.

    Main Methods:

    • Iliac crest bone biopsies were analyzed from 38 men with alcoholism and a control group.
    • Osteoclast activity was quantified by counting osteoclasts per bone section.
    • Osteoid abundance was measured as the percentage of trabecular bone surface covered by osteoid.

    Main Results:

    • Alcoholic men exhibited significantly higher osteoclast numbers compared to nonalcoholic controls.
    • Osteoid seam thickness increased only in alcoholics with a history of gastric resection.
    • No advanced osteomalacia was observed, indicating relatively slight nutritional effects on bone.

    Conclusions:

    • Alcoholism is characterized by increased bone resorption due to heightened osteoclast activity.
    • Gastric resection may exacerbate alcohol-induced skeletal changes.
    • Alcoholism induces systemic and local bone alterations, impacting skeletal health.
