IgA Nephropathy

IgA Nephropathy, also known as Berger’s disease, is a kidney disorder that occurs when the immunoglobulin A (IgA) protein builds up in the kidneys. This buildup can lead to inflammation and damage to the kidneys over time, potentially resulting in kidney failure. It is one of the most common forms of kidney disease worldwide, especially in young adults and adolescents.

Pathophysiology of IgA Nephropathy

Structure of the Kidneys

The kidneys are bean-shaped organs located on either side of the spine. They filter waste products from the blood and produce urine. Each kidney contains:

• Nephrons: The functional units that filter blood and produce urine.
• Glomeruli: Tiny clusters of blood vessels within the nephrons where blood filtration occurs.

Blood and Nerve Supply

• Blood Supply: The kidneys receive blood from the renal arteries, which branch off from the aorta. They filter about 50 gallons of blood daily.
• Nerve Supply: The kidneys are innervated by the autonomic nervous system, which regulates their function and blood flow.

Pathophysiological Process

In IgA Nephropathy, IgA antibodies accumulate in the glomeruli. This can trigger an immune response, causing inflammation and damage to the kidney tissue. Over time, repeated damage can lead to scarring and reduced kidney function.

Types of IgA Nephropathy

1. Primary IgA Nephropathy: The most common type, where the disease arises without any underlying condition.
2. Secondary IgA Nephropathy: Occurs as a result of other diseases, such as liver disease, celiac disease, or infections.

Causes of IgA Nephropathy

While the exact cause is not fully understood, several factors may contribute to the development of IgA Nephropathy:

1. Genetic predisposition
2. Abnormal immune response
3. Viral infections (e.g., Epstein-Barr virus)
4. Bacterial infections (e.g., strep throat)
5. Chronic liver disease
6. Celiac disease
7. Diabetes
8. Hypertension
9. Environmental factors (e.g., exposure to toxins)
10. Allergies
11. Smoking
12. Obesity
13. High-fat diets
14. Excessive alcohol consumption
15. Low vitamin D levels
16. Frequent respiratory infections
17. Autoimmune diseases (e.g., lupus)
18. IgA deficiency
19. Genetic mutations
20. Stress

Symptoms of IgA Nephropathy

Symptoms may vary among individuals and can develop gradually. Common symptoms include:

1. Blood in the urine (hematuria)
2. Dark or foamy urine
3. Swelling in the legs, ankles, or feet (edema)
4. High blood pressure
5. Fatigue
6. Abdominal pain
7. Nausea
8. Vomiting
9. Frequent urination
10. Decreased urine output

Diagnostic Tests for IgA Nephropathy

To diagnose IgA Nephropathy, healthcare providers may perform several tests:

1. Urinalysis: Checks for blood and protein in the urine.
2. Blood tests: Measures kidney function and the level of IgA.
3. 24-hour urine collection: Evaluates protein excretion over a day.
4. Imaging tests: Ultrasound or CT scans to examine the kidneys.
5. Kidney biopsy: A small sample of kidney tissue is examined for IgA deposits.
6. Serum creatinine test: Measures the level of creatinine in the blood to assess kidney function.
7. Blood urea nitrogen (BUN) test: Assesses waste products in the blood.
8. Electrolyte panel: Checks the balance of electrolytes in the blood.
9. Lipid profile: Evaluates cholesterol and triglyceride levels.
10. Complement levels: Measures specific proteins that help fight infections.
11. Autoimmune tests: Identifies underlying autoimmune disorders.
12. Genetic testing: Looks for genetic markers associated with kidney disease.
13. Microscopic examination: Analyzes urine samples for cells and crystals.
14. Immunofluorescence microscopy: Used during kidney biopsy to detect IgA deposits.
15. Renal function tests: Evaluates overall kidney performance.
16. CT or MRI scans: Provides detailed images of kidney structure.
17. Serum IgA levels: Measures the amount of IgA in the blood.
18. Thyroid function tests: Assesses thyroid health as part of systemic evaluation.
19. Hepatitis screening: Checks for viral hepatitis, which can affect the kidneys.
20. HLA typing: Determines tissue types that might affect the risk of IgA nephropathy.

Non-Pharmacological Treatments for IgA Nephropathy
