Nephrotic Syndrome I : Introduction01:24

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...

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...
Type I Diabetes II: Pathophysiology01:26

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...

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.
Type I Diabetes III: Clinical Manifestations01:19

Type I Diabetes III: Clinical Manifestations

Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...
Type II Diabetes I: Introduction01:26

Type II Diabetes I: Introduction

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...

Area of Science:

  • Metabolic Medicine
  • Hepatology
  • Endocrinology

Background:

  • Metabolic syndrome is a precursor to Type-2 diabetes and Coronary Artery Disease (CAD).
  • Insulin resistance is a central factor in metabolic syndrome and Non-Alcoholic Fatty Liver Disease (NAFLD) development.

Purpose of the Study:

  • To determine the prevalence of NAFLD in individuals with metabolic syndrome.
  • To investigate the role of metabolic risk factors in causing NAFLD among non-diabetic North Indian males.

Main Methods:

  • Study included 495 non-diabetic, non-alcoholic males aged 30-65 years.
  • Metabolic syndrome diagnosed using ATP III and ADA (2005) criteria.
  • NAFLD assessed via liver ultrasonography; insulin resistance measured using Homeostasis Model Assessment (HOMA) and QUICKI index.

Main Results:

  • Prevalence of metabolic syndrome and NAFLD was 24% and 14.8% respectively.
  • 27% of metabolic syndrome patients had NAFLD, linked to hyperinsulinemia, insulin resistance, and elevated metabolic risk factors.
  • NAFLD prevalence correlated positively with insulin resistance and the clustering of metabolic risk factors.

Conclusions:

  • Metabolic syndrome and NAFLD are prevalent in the studied population.
  • Insulin resistance and associated metabolic abnormalities are key drivers for NAFLD development in non-diabetic males.
