    Insights

    In diabetics, elevated alpha-2-macroglobulin and reduced mononuclear phagocytic system function contribute to blood vessel damage (angiopathy). Disturbed immune balance and infections also play a role in diabetes complications.

    Area of Science:

    • Immunology
    • Diabetology
    • Vascular Biology

    Background:

    • Diabetes mellitus is associated with micro- and macro-angiopathy.
    • The pathogenesis of diabetic vascular complications is multifactorial.

    Purpose of the Study:

    • To investigate the role of alpha-2-macroglobulin and mononuclear phagocytic system function in diabetic angiopathy.
    • To explore the contribution of immunobalance and infection to diabetic vascular complications.

    Main Methods:

    • Analysis of alpha-2-macroglobulin levels.
    • Assessment of mononuclear phagocytic system functional capacity.
    • Evaluation of immune balance and infection parameters in diabetic patients.

    Main Results:

    • Increased alpha-2-macroglobulin levels were observed in diabetics.
    • Decreased functional capacity of the mononuclear phagocytic system was noted.
    • Disturbed immunobalance and specific infection/inflammation patterns were identified.

    Conclusions:

    • Elevated alpha-2-macroglobulin and impaired mononuclear phagocytic system function are key factors in diabetic angiopathy.
    • Immunological disturbances and infections contribute significantly to the development and progression of vascular complications in diabetes.

    Drug Dosing in Renal Diseases: Measurement of Glomerular Filtration Rate

    The glomerular filtration rate (GFR) is a critical indicator of kidney health, reflecting how well the kidneys filter blood. Changes in GFR can signal potential kidney impairment, necessitating accurate measurement methods to monitor kidney function effectively.Various molecules can serve as markers for GFR measurement, with the ideal marker meeting several specific criteria. It must freely filter at the glomerulus, avoid reabsorption or secretion by the renal tubules, remain unmetabolized, not...
