Dasatinib is a medication commonly used to treat certain types of blood cancers, particularly chronic myeloid leukemia (CML). While effective, it can lead to a condition known as nephrotic-range proteinuria, which is characterized by a significant amount of protein in the urine. This article aims to explain this condition in simple terms, covering its causes, symptoms, diagnosis, treatments, and more.
Nephrotic-range proteinuria refers to the presence of an excessive amount of protein in the urine, usually defined as more than 3.5 grams per day. This condition is a sign of kidney damage and can lead to various complications.
Pathophysiology
Structure of the Kidneys
- Nephrons: The functional units of the kidneys, responsible for filtering blood and producing urine.
- Glomeruli: Tiny filters within the nephrons that prevent large proteins from entering the urine.
Blood Supply
- Renal Artery: Supplies blood to the kidneys.
- Renal Vein: Drains blood away from the kidneys after filtration.
Nerve Supply
- Autonomic Nervous System: Controls kidney functions, including blood flow and urine production.
Types of Nephrotic Syndrome
- Minimal Change Disease
- Focal Segmental Glomerulosclerosis (FSGS)
- Membranous Nephropathy
- Diabetic Nephropathy
- Lupus Nephritis
Causes of Dasatinib-Induced Nephrotic-Range Proteinuria
