Nephrotic Syndrome

Definition: Nephrotic syndrome is a collection of symptoms that occur when the kidneys are damaged and can't filter waste properly, leading to the loss of large amounts of protein in the urine.
Causes / Etiology: The exact cause of nephrotic syndrome is not known but it is often associated with autoimmune diseases, infections, and exposure to certain toxins or drugs. It can be primary (idiopathic) or secondary (caused by other conditions).
Types or Classification:

Minimal Change Disease: Characterized by minimal changes in the kidney tissue and typically affects children.
Focal Segmental Glomerulosclerosis (FSGS): Involves scarring of the glomeruli and is often secondary to other conditions.
Membranous Nephropathy: Characterized by thickening of the glomerular basement membrane and is often associated with autoimmune diseases.
Membranoproliferative Glomerulonephritis: Involves thickening and proliferation of the glomerular basement membrane and is often secondary to infections or autoimmune diseases.
Diabetic Nephropathy: A complication of diabetes that damages the kidneys.

Pathology: Step 1 → The kidneys filter waste and excess fluids from the blood, but in nephrotic syndrome, the kidneys are damaged and can't filter properly. Step 2 → The damaged kidneys leak large amounts of protein, including albumin, into the urine. Step 3 → The loss of protein leads to a decrease in blood volume and a decrease in the blood's ability to clot, increasing the risk of bleeding. Step 4 → The kidneys also produce less urine, leading to a buildup of waste products in the blood. Step 5 → In some cases, the kidneys may also produce excess amounts of certain hormones, such as aldosterone and renin, which can further increase blood pressure.
Clinical Features:

General features: weight loss, fatigue, swelling in the legs and feet, and high blood pressure.
Specific features: proteinuria (excess protein in the urine), hypoalbuminemia (low albumin levels in the blood), hyperlipidemia (high levels of lipids in the blood), and edema (swelling).

Acute Complications: Hyperkalemia (high potassium levels), acidosis, and acute kidney injury.
Chronic Complications: End-stage renal disease, cardiovascular disease, and an increased risk of infections.

Routine Tests: Blood tests to check for kidney function, urine tests to check for protein and blood, and an electrocardiogram (ECG) to check for cardiac damage.
Special Tests: A biopsy of the kidney tissue to confirm the diagnosis and determine the cause of the nephrotic syndrome.

General Management: Rest, diet, and medication to control blood pressure and fluid balance.
Modern Treatment: Corticosteroids and immunosuppressive medications to reduce inflammation and prevent further damage.
Dietary Advice: A low-sodium diet, a diet high in protein and calories to help maintain weight, and a diet that limits the intake of sugar and fat.
