    •       chronic:  gradual muscle wasting and weakness, no pain or elevated muscle enzymes, thought to be the result of vit. B defiency

    • Improvement with alcohol abstinence and nutritious diet is seen
    • -Wernickes encephalopathy

    • -Leukopenia
    • -Thrombocytopenia; platelet production and survival are impaired.... risk for hemorrhage
    • -Sexual dysfunction

    100 and 200 mg/dL

    death occurs at 400 to 700 mg/dL
