Elevated plasma triglyceride levels are associated with human protoporphyria.

M B Poh-Fitzpatrick, R H Palmer

    The Journal of Laboratory and Clinical Medicine
    |August 1, 1984
    PubMed
    Summary

    Mild hypertriglyceridemia is more common in patients with protoporphyria. Beta-carotene therapy did not increase triglyceride levels and may even lower them in some individuals.

    Area of Science:

    • Biochemistry
    • Metabolic Disorders
    • Dermatology

    Background:

    • Protoporphyria is a rare genetic disorder affecting heme synthesis.
    • Elevated triglyceride levels are a common metabolic abnormality.

    Purpose of the Study:

    • To investigate the prevalence of hypertriglyceridemia in protoporphyria patients.
    • To assess the impact of beta-carotene therapy on triglyceride levels in these patients.

    Main Methods:

    • Fasting plasma lipid profiles were measured in protoporphyria patients.
    • Triglyceride levels were compared to a matched control population.
    • The effect of beta-carotene administration on triglyceride levels was evaluated.

    Main Results:

    • Protoporphyria patients showed a significantly higher frequency of mild hypertriglyceridemia.
    • Beta-carotene therapy did not elevate triglyceride levels.
    • Eight out of 13 patients experienced lower triglyceride levels during beta-carotene therapy.

    Conclusions:

    • Mild hypertriglyceridemia is associated with protoporphyria.
    • Beta-carotene therapy is safe concerning triglyceride levels and may be beneficial.
