Insights

Renal denervation (RDN) shows promise for treating resistant hypertension and improving glucose metabolism. This minimally invasive procedure may offer a new option for patients with both hypertension and diabetes.

Area of Science:

  • Cardiovascular Medicine
  • Metabolic Disorders
  • Interventional Cardiology

Background:

  • Hypertension and diabetes are leading causes of cardiovascular disease.
  • Optimal control of blood pressure and glucose remains challenging despite available therapies.
  • Sympathetic nervous system overactivity contributes to hypertension and related comorbidities.

Purpose of the Study:

  • To evaluate the role of catheter-based sympathetic renal denervation (RDN) in managing treatment-resistant hypertension.
  • To explore the potential impact of RDN on glucose metabolism, including fasting glucose, insulin levels, and HOMA index.
  • To assess RDN as a therapeutic option for patients with resistant hypertension and altered glucose metabolism.

Main Methods:

  • Catheter-based sympathetic renal denervation (RDN) procedure.
  • Monitoring of blood pressure control.
  • Assessment of glycemic control parameters: fasting glucose, insulin levels, and Homeostasis Model Assessment (HOMA) index.

Main Results:

  • RDN has emerged as a significant treatment for resistant hypertension.
  • Preliminary data suggest RDN may improve blood pressure control.
  • Early findings indicate potential reductions in fasting glucose and insulin, and improved HOMA index.

Conclusions:

  • RDN is a promising intervention for resistant hypertension.
  • RDN may offer benefits for glycemic control in patients with coexisting hypertension and diabetes.
  • Further large-scale controlled trials are needed to confirm these findings and establish RDN as a preferred treatment.

Antihypertensive Drugs: Direct Renin Inhibitors

The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...

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...

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...

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.

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...
Insulin: The Receptor and Signaling Pathways01:28

Insulin: The Receptor and Signaling Pathways

Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but this inhibition is released...
