Membranous Nephropathy is a kidney disorder that affects the glomeruli, which are tiny filtering units in the kidneys. In this condition, the membranes surrounding the glomeruli become thickened due to the buildup of immune complexes. This can lead to problems with filtering blood and can result in nephrotic syndrome, characterized by significant protein loss in urine.
Pathophysiology
- Structure: Membranous Nephropathy primarily affects the glomerular basement membrane. In healthy kidneys, this membrane acts as a barrier to prevent large proteins from entering the urine. In this condition, the membrane thickens, disrupting its function.
- Blood Supply: The kidneys receive blood from the renal artery, which branches off from the abdominal aorta. Proper blood flow is crucial for the kidneys to filter waste and maintain fluid balance.
- Nerve Supply: The kidneys are innervated by the autonomic nervous system, which regulates blood flow and kidney function. This nerve supply is essential for responding to the body’s needs, such as regulating blood pressure.
Types of Membranous Nephropathy
- Primary (Idiopathic): Occurs without a known cause, often linked to autoimmune disorders.
- Secondary: Related to other medical conditions, such as infections, drugs, or cancers.
Causes of Membranous Nephropathy
