Harvoni Induced Renal Injury refers to kidney damage that may occur as a side effect of taking Harvoni. Harvoni is a medication used to treat chronic hepatitis C, a viral infection that affects the liver. While Harvoni is generally well-tolerated, understanding its potential impact on kidney health is essential for patients and healthcare providers.
Harvoni is a combination medication containing two active ingredients: ledipasvir and sofosbuvir. It is used to treat hepatitis C, a liver infection caused by the hepatitis C virus (HCV). Harvoni works by stopping the virus from multiplying, helping to clear the infection from the body.
Key Points:
- Uses: Treats chronic hepatitis C
- Components: Ledipasvir and Sofosbuvir
- Administration: Oral tablet, usually taken once daily with food
Renal injury, also known as kidney damage, affects the kidneys’ ability to filter waste and excess fluids from the blood. This can lead to a buildup of harmful substances in the body, causing various health issues.
Key Functions of the Kidneys:
- Filtering blood to remove waste
- Balancing fluids and electrolytes
- Regulating blood pressure
- Producing hormones that affect other bodily functions
Pathophysiology of Harvoni Induced Renal Injury
Structure of the Kidneys
The kidneys are bean-shaped organs located on either side of the spine, just below the rib cage. Each kidney contains about one million tiny filtering units called nephrons. Nephrons remove waste and excess substances from the blood, forming urine.
Blood Supply
The kidneys receive blood through the renal arteries. Blood flows into the nephrons, where filtration occurs. Clean blood exits through the renal veins back into the bloodstream.
Nerve Supply
The kidneys are connected to the nervous system via the renal plexus, which controls blood flow and other kidney functions.
Harvoni’s Impact: While Harvoni primarily targets the liver to treat hepatitis C, its components may affect kidney function indirectly by altering blood flow, causing inflammation, or leading to electrolyte imbalances.
Types of Renal Injury
- Acute Kidney Injury (AKI): Sudden loss of kidney function.
- Chronic Kidney Disease (CKD): Gradual loss of kidney function over time.
- Interstitial Nephritis: Inflammation of the kidney’s tubules and surrounding structures.
- Nephrotic Syndrome: Excessive protein loss in urine.
