Nephrotic Syndrome

Nephrotic Syndrome is a kidney disorder that causes your body to excrete too much protein in your urine. Understanding Nephrotic Syndrome is crucial for managing health and preventing complications. This guide provides detailed yet simple explanations of Nephrotic Syndrome, including its causes, symptoms, treatments, and more.

Nephrotic Syndrome is a condition where the kidneys leak an excessive amount of protein into the urine. This protein loss leads to various symptoms, including swelling, high cholesterol, and increased risk of infections. The syndrome results from damage to the kidney’s filtering units called glomeruli.


Pathophysiology

Understanding how Nephrotic Syndrome affects the body involves looking at the kidneys’ structure, how they filter blood, and their nerve supply.

Kidney Structure

  • Glomeruli: Tiny blood vessels in the kidneys that filter waste and excess fluids from the blood.
  • Tubules: Structures that process the filtered fluid into urine.
  • Bowman’s Capsule: Surrounds the glomeruli and collects the filtered fluid.

Blood and Protein Filtration

Under normal conditions, glomeruli act like a sieve, allowing waste and excess substances to pass into the urine while retaining essential proteins and blood cells. In Nephrotic Syndrome:

  1. Damage to Glomeruli: Makes the filtration barrier leaky.
  2. Protein Leakage: Large amounts of protein, especially albumin, escape into the urine.
  3. Low Blood Protein Levels: Reduced protein in the blood causes fluid to leak into tissues, leading to swelling.

Nerve Supply

The kidneys receive nerve signals that help regulate blood flow and filtration rates. Disruptions in nerve supply can affect kidney function and exacerbate Nephrotic Syndrome symptoms.


Types of Nephrotic Syndrome

Nephrotic Syndrome can be categorized based on its origin:

  1. Primary (Idiopathic): Originates in the kidneys without a known systemic disease.
  2. Secondary: Results from other diseases or conditions affecting the kidneys, such as:
    • Diabetes
    • Lupus
    • Infections
    • Certain medications

Additionally, it can be classified by the underlying cause affecting the glomeruli:

  • Minimal Change Disease
  • Focal Segmental Glomerulosclerosis (FSGS)
  • Membranous Nephropathy

Causes of Nephrotic Syndrome

Nephrotic Syndrome can be triggered by various conditions. Here are 20 potential causes:

  1. Diabetes Mellitus: High blood sugar damages kidneys.
  2. Lupus (Systemic Lupus Erythematosus): An autoimmune disease attacking kidney tissues.
  3. Infections: Such as hepatitis B and C, HIV, and malaria.
  4. Membranous Nephropathy: Thickening of the kidney’s filtering units.
  5. Focal Segmental Glomerulosclerosis (FSGS): Scarring in parts of the glomeruli.
  6. Minimal Change Disease: Causes significant protein loss with minimal changes seen under a microscope.
  7. Amyloidosis: Buildup of abnormal proteins in organs, including kidneys.
  8. Multiple Myeloma: A cancer of plasma cells affecting kidneys.
  9. Pre-eclampsia: A pregnancy complication causing high blood pressure and kidney damage.
  10. Certain Medications: Such as nonsteroidal anti-inflammatory drugs (NSAIDs).
  11. Amyloidosis: Accumulation of amyloid proteins in kidneys.
