Glomerulonephritis is a condition characterized by inflammation of the glomeruli, which are the tiny filtering units in the kidneys. This inflammation can impair the kidneys' ability to filter waste and excess fluids from the blood, potentially leading to kidney damage.



Types of Glomerulonephritis:

  1. Acute Glomerulonephritis:

    • A sudden onset of inflammation, often following a throat or skin infection, such as strep throat. It may resolve with treatment or lead to chronic kidney issues.
  2. Chronic Glomerulonephritis:

    • A slow, progressive damage to the kidneys that can lead to kidney failure over time. This form often develops over many years and can result from conditions like high blood pressure or diabetes.
  3. Rapidly Progressive Glomerulonephritis (RPGN):

    • A severe form where kidney function rapidly deteriorates, leading to kidney failure within weeks to months. This type requires immediate treatment.
  4. Focal Segmental Glomerulosclerosis (FSGS):

    • Involves scarring of some of the glomeruli, which can lead to protein loss in the urine and kidney damage.
  5. Membranous Nephropathy:

    • Characterized by thickening of the glomerular membrane, often causing significant proteinuria (protein in the urine).

Symptoms:

  • Swelling (edema), especially in the face, hands, and feet
  • Blood in the urine (hematuria), giving it a reddish or cola-like color
  • Foamy urine due to excess protein (proteinuria)
  • High blood pressure
  • Decreased urine output
  • Fatigue
  • Nausea and vomiting (in severe cases)

Causes:

  • Infections: Streptococcal infections, viral infections like hepatitis, or bacterial endocarditis.
  • Autoimmune Diseases: Conditions like lupus, Goodpasture syndrome, and vasculitis can cause the immune system to attack the kidneys.
  • Genetic Conditions: Some forms of glomerulonephritis run in families, such as Alport syndrome.
  • Diabetes and Hypertension: Long-term high blood pressure or poorly controlled diabetes can lead to kidney damage.

Diagnosis:

  • Urine Tests: To detect blood and protein in the urine.
  • Blood Tests: To measure kidney function (e.g., creatinine levels) and check for underlying conditions.
  • Kidney Biopsy: A sample of kidney tissue may be examined under a microscope to determine the type and extent of damage.
  • Imaging: Ultrasound or CT scans may be used to assess kidney size and structure.

Treatment:

Treatment depends on the underlying cause and type of glomerulonephritis, but may include:

  • Medications:
    • Corticosteroids and immunosuppressants to reduce inflammation.
    • Antihypertensive drugs to control blood pressure.
    • Diuretics to reduce fluid retention.
    • Medications to control cholesterol or blood sugar levels.
  • Dietary Changes: A low-salt, low-protein diet may be recommended to reduce strain on the kidneys.
  • Dialysis: In severe cases, where kidney function fails, dialysis may be required to perform the kidneys' filtration role.
  • Plasmapheresis: A procedure to remove harmful antibodies from the blood in cases of severe autoimmune-related glomerulonephritis.

Prognosis:

The prognosis for glomerulonephritis varies widely. Some people recover fully with treatment, especially in cases of acute glomerulonephritis. However, chronic or severe forms can lead to kidney failure, requiring long-term management and possibly a kidney transplant.

If you suspect you have glomerulonephritis, it's essential to seek medical attention promptly for proper diagnosis and treatment.
