IgA-Dominant Post-Infectious Glomerulonephritis (IgA-D PGN) is a kidney condition that often follows an infection. It primarily affects how your kidneys filter blood. This article will explain what IgA-D PGN is, its causes, symptoms, diagnostic tests, treatments, and when to seek medical help.
IgA-Dominant PGN is a type of kidney inflammation that occurs after an infection, where the immune system produces an excess of Immunoglobulin A (IgA). This antibody can deposit in the kidneys and lead to inflammation, affecting their filtering ability.
Pathophysiology
Structure of the Kidneys
The kidneys are two bean-shaped organs located on either side of your spine, just below your rib cage. They contain tiny structures called nephrons that filter waste and excess fluids from the blood.
Blood Supply
The kidneys receive blood through the renal arteries. This blood supply is crucial for the kidneys to perform their filtering functions.
Nerve Supply
The kidneys are connected to the nervous system, which helps regulate blood pressure and fluid balance, affecting how the kidneys filter blood.
Types of IgA-Dominant Glomerulonephritis
- IgA Nephropathy: The most common form, often occurring without a preceding infection.
- Post-infectious IgA Glomerulonephritis: This occurs after infections, particularly respiratory or gastrointestinal ones.
Causes
- Recent infections (e.g., respiratory, skin, or urinary tract)
- Genetic predisposition
- Immune system disorders
- Viral infections (e.g., hepatitis, HIV)
- Bacterial infections (e.g., streptococcus)
- Vaccinations (rarely)
- Environmental factors (e.g., exposure to toxins)
- Chronic diseases (e.g., diabetes)
- Allergic reactions
- HIV/AIDS
- Certain medications (e.g., antibiotics)
- Blood disorders
- Obesity
- Hypertension
- Alcoholism
- Smoking
- Traveling to areas with endemic infections
- Fungal infections
- Parasitic infections
- Autoimmune diseases (e.g., lupus)
Symptoms
- Swelling in the legs and feet
- High blood pressure
- Foamy urine (indicating protein in urine)
- Blood in urine
- Fatigue
- Nausea
- Vomiting
- Loss of appetite
- Weight gain (due to fluid retention)

- Confusion (in severe cases)
- Changes in urine output
- Dry skin
- Fever (occasionally)
Diagnostic Tests
- Urinalysis: Checks for blood and protein in the urine.
- Blood tests: Measures kidney function and antibody levels.
- Kidney ultrasound: Uses sound waves to create images of the kidneys.
- CT scan: Provides detailed images of the kidneys.
- MRI: Another imaging technique to view kidney structure.
- Kidney biopsy: Removes a small kidney sample for examination.
- 24-hour urine collection: Measures how much protein is lost in urine.
- Electrolyte panel: Checks levels of electrolytes in the blood.
- Complete blood count (CBC): Assesses overall health and detects disorders.
- Serum creatinine test: Evaluates kidney function.
- Lipid profile: Checks cholesterol levels.
- Antibody tests: Identifies specific antibodies related to infections.
- Complement levels: Measures components of the immune system.
- Streptococcal antibody tests: Looks for prior streptococcus infection.
- Viral load tests: Determines the presence of viral infections.
- Urine protein-to-creatinine ratio: Assesses protein levels in urine.
- C-reactive protein test: Measures inflammation in the body.
- Kidney function tests: Assesses how well the kidneys are working.
- Genetic testing: Identifies hereditary factors if applicable.
- Urine culture: Checks for urinary tract infections.
Non-Pharmacological Treatments
