Post-infectious glomerulonephritis is a condition that affects the kidneys. It occurs after an infection, usually a throat or skin infection. This illness causes inflammation in the glomeruli, the tiny filters in the kidneys that clean the blood. When the glomeruli become inflamed, they can’t filter waste and excess fluid from the blood effectively, leading to various health issues.
Pathophysiology (Structure, Blood, Nerve Supply)
Structure
- Glomeruli: These are tiny structures in the kidneys responsible for filtering blood. Each kidney contains about a million glomeruli.
- Nephrons: The glomeruli are part of nephrons, the basic functional units of the kidney, which help in urine formation.
Blood Supply
- The kidneys receive blood from the renal arteries, which branch off from the abdominal aorta.
- Blood flows through the glomeruli, where filtration occurs. The filtered blood then continues through the renal tubules, where further processing occurs.
Nerve Supply
- The kidneys are innervated by the autonomic nervous system, which regulates their functions. This nerve supply helps control blood flow and the filtration process.
Types of Post-infectious Glomerulonephritis
- Acute Post-infectious Glomerulonephritis: This is the most common type, often occurring after a bacterial infection.
- Chronic Post-infectious Glomerulonephritis: This is less common and may develop slowly over time, possibly leading to long-term kidney damage.
Causes of Post-infectious Glomerulonephritis
- Streptococcal Infection: Often follows strep throat or skin infections.
- Viral Infections: Such as hepatitis, HIV, and chickenpox.
- Bacterial Infections: Like endocarditis (infection of the heart valves).
- Skin Infections: Including impetigo.
- Autoimmune Diseases: Conditions where the immune system attacks the body, like lupus.
