    Summary
    This summary is machine-generated.

    Vasolastine enzyme therapy shows promise for improving lipid profiles in elderly individuals. It reduces total cholesterol and increases HDL-cholesterol, potentially lowering cardiovascular disease risk in younger elderly groups.

    Area of Science:

    • Biochemistry
    • Gerontology
    • Cardiovascular Medicine

    Background:

    • Age-related enzyme deficits impact lipid metabolism, contributing to cardiovascular diseases.
    • Enzyme replacement therapy faces challenges due to enzyme size and immunogenicity.
    • Vasolastine is an enzyme preparation developed to address lipid metabolism disorders.

    Purpose of the Study:

    • To evaluate the efficacy of Vasolastine in modifying plasma lipid profiles in elderly subjects.
    • To assess the impact of Vasolastine on total cholesterol and HDL-cholesterol levels across different age groups within the elderly population.

    Main Methods:

    • Intramuscular administration of Vasolastine to elderly subjects across various age ranges (60-95 years).
    • Measurement of total plasma cholesterol and HDL-cholesterol levels before and after treatment.

  • Calculation of the total cholesterol to HDL-cholesterol ratio.

    • Main Results:

    • Vasolastine reduced total cholesterol by 13% in the 75-80 age group, with smaller increases at younger and older extremes.
    • HDL-cholesterol levels increased by 5% across all age groups.
    • The total cholesterol to HDL-cholesterol ratio decreased by approximately 6% up to age 80, with a lesser reduction above 80.

    Conclusions:

    • Vasolastine effectively modifies plasma lipid profiles in the elderly, with a notable reduction in cardiovascular risk markers up to age 80.
    • The enzyme preparation demonstrates a reduced, though still present, protective effect in the oldest age group (above 80).
    • Vasolastine shows potential as a therapeutic agent for managing age-related lipid metabolism dysfunctions and associated cardiovascular risks.
