    Insights

    This study reveals that diabetes mellitus significantly alters blood clotting (hemostasis), contributing to diabetic retinopathy. Impaired hemostasis, including hypercoagulation, plays a key role in the development of this eye condition.

    Area of Science:

    • Cardiovascular Medicine
    • Endocrinology
    • Ophthalmology

    Background:

    • Diabetes mellitus is a systemic disease with known microvascular complications.
    • Diabetic retinopathy is a leading cause of vision loss in diabetic patients.
    • The role of hemostasis in diabetic retinopathy pathogenesis requires further elucidation.

    Purpose of the Study:

    • To investigate the hemostatic system in patients with diabetes mellitus.
    • To correlate hemostatic changes with the severity of diabetic retinopathy.
    • To understand the contribution of hemostasis to the development of diabetic retinopathy.

    Main Methods:

    • Analysis of coagulogram and thromboelastogram parameters.
    • Assessment of platelet aggregation stimulated by collagen.
    • Evaluation of plasma fibrinolytic activity, plasminogen, fibrinogen, and fibrin-degradation products.

    Main Results:

    • Patients exhibited generalized hypercoagulation.
    • Lower activity of the antithrombin III-heparin system was observed.
    • Increased fibrinogen activity and fibrinolytic system activation correlated with retinopathy severity.

    Conclusions:

    • Impaired hemostasis is significantly associated with diabetic retinopathy.
    • Hemostatic system alterations are crucial in the pathogenesis of diabetic retinopathy.
    • Targeting hemostasis may offer therapeutic strategies for diabetic retinopathy.

    Diabetic Retinopathy

    DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

    Diabetic Nephropathy

    Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
    Complications of Diabetes Mellitus01:22

    Complications of Diabetes Mellitus

    Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...

    Diabetic Foot Ulcer

    Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
    Disorders of Hemostasis01:24

    Disorders of Hemostasis

    Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
    Thromboembolic Disorders
    Two factors primarily cause thromboembolic conditions.
    Diabetic Neuropathy01:22

    Diabetic Neuropathy

    DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
