  1. Prevalence of hereditary Hemochromatosis in 16 031 primary care Patients : Iron overload, public health, and genetics.

    Article - En anglais

    Background 

    Despite evidence from screening studies in northern European populations, the prevalence of hemochromatosis in primary care populations in the United States remains speculative.

    Objective 

    To establish the feasibility of screening for hemochromatosis and to estimate the prevalence of hemochromatosis in a large primary care population.

    Design 

    Cross-sectional prevalence study.

    Setting 

    22 primary care practices in the Rochester, New York, area.

    Patients 

    16 031 ambulatory patients without a previous diagnosis of hemochromatosis.

    Intervention 

    Serum transferrin saturation screening tests were offered to all adult patients in participating primary care practices.

    Measurements 

    Patients with a serum transferrin saturation of 45% or more on initial testing had a serum transferrin saturation test done under fasting conditions and had serum ferritin levels measured.

    Those who had a fasting serum transferrin saturation of 55% or more and a serum ferritin level of 200 mug/L or more with no other apparent cause were presumed to have hemochromatosis and were offered liver biopsy to confirm the diagnosis.

    Results 

    25 patients had biopsy-proven hemochromatosis ; 22 patients met the clinical criteria for hemochromatosis but declined liver biopsy and were classified as having clinically proven hemochromatosis ; and 23 patients had a serum transferrin saturation of 55% or more with no identifiable cause, indicating probable hemochromatosis.
