Diabetic microangiopathy involves increased capillary permeability, affecting 39% of patients. Early lymphatic dysfunction and elevated albumin retention (AR) are key indicators, particularly in women and those without complications.

Area of Science:

  • Vascular Biology
  • Endocrinology
  • Diabetology

Background:

  • Microangiopathic disorders, common in diabetes, feature capillary changes preceding complications.
  • Capillary vasodilation, increased blood flow, and permeability are hallmarks of diabetic microangiopathy.

Purpose of the Study:

  • To investigate capillary permeability and lymphatic function in diabetic patients.
  • To identify factors associated with increased capillary permeability and lymphatic abnormalities.

Main Methods:

  • Assessed capillary permeability via albumin retention (AR) in 163 diabetic patients.
  • Evaluated lymphatic function and correlated findings with patient demographics and complication status.

Main Results:

  • Increased AR was observed in 39% of patients, more prevalent in women and those without microangiopathic complications.
  • Abnormal lymphatic function was detected in 72% of patients, often preceding increased AR.
  • Elevated AR correlated with insulin-dependent diabetes in male patients.

    • Conclusions:

    • Capillary permeability and lymphatic dysfunction are significant early indicators in diabetic microangiopathy.
    • Glycemic and blood pressure control, along with potential interventions like flavonoids and n-3 fatty acids, may improve capillary function.
