  • Endocrinology

Background:

  • Diabetes mellitus is a global health issue with severe cardiovascular and renal complications, leading to significant mortality.
  • MicroRNAs (miRNAs), a class of short non-coding RNAs, play crucial roles in regulating pathological processes.
  • Emerging research highlights miRNAs as potential therapeutic agents for managing diabetes-related organ damage.

Purpose of the Study:

  • To review the current understanding of microRNA involvement in diabetes mellitus.
  • To discuss the clinical applications of miRNAs in preventing and treating diabetes complications.
  • To focus on the potential of miRNAs in repairing cardiovascular and renal damage caused by diabetes.

Main Methods:

  • Literature review of scientific articles on microRNAs and diabetes.
  • Analysis of studies investigating miRNA function in diabetic pathophysiology.
  • Synthesis of information regarding clinical trials and therapeutic strategies involving miRNAs.

Main Results:

  • MicroRNAs are implicated in the pathogenesis of diabetic complications affecting multiple organs.
  • Specific miRNAs have been identified as potential biomarkers for early detection of diabetic complications.
  • Therapeutic strategies using miRNAs demonstrate potential in preclinical models for cardiovascular and renal protection.

Conclusions:

  • MicroRNAs represent a promising therapeutic avenue for mitigating diabetes-induced cardiovascular and renal pathologies.
  • Further research and clinical trials are warranted to fully harness the therapeutic potential of miRNAs in diabetes management.

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...

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...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System01:26

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

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...

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Type II Diabetes II: Pathophysiology

PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
