Nephrotoxicity

Nephrotoxicity is a term used to describe kidney damage caused by drugs, toxins, or other substances. It is a significant concern in the medical field due to the vital role the kidneys play in the body's overall health. The kidneys are responsible for filtering waste and excess substances from the blood, which are then excreted in the urine. When the kidneys are damaged, they may not function properly, leading to a variety of health problems.

Causes

Nephrotoxicity can be caused by a variety of substances, including certain medications, environmental toxins, and illegal drugs. Some of the most common causes include:

• Nonsteroidal anti-inflammatory drugs (NSAIDs)
• Antibiotics
• Chemotherapy drugs
• Radiographic contrast media
• Heavy metals
• Alcohol
• Illegal drugs

Symptoms

The symptoms of nephrotoxicity can vary greatly depending on the cause and severity of the kidney damage. Some people may not experience any symptoms, while others may experience:

• Fatigue
• Swelling in the legs, ankles, or feet
• Shortness of breath
• Confusion
• Nausea
• Seizures
• Coma

Diagnosis

Diagnosing nephrotoxicity involves a variety of tests and procedures, including:

• Blood tests
• Urine tests
• Imaging tests
• Kidney biopsy

Treatment

Treatment for nephrotoxicity depends on the cause and severity of the kidney damage. In some cases, stopping or changing the medication or substance causing the damage may be enough to reverse the damage. In other cases, treatment may involve:

• Dialysis
• Medications
• Dietary changes
• Kidney transplant

Prevention

Preventing nephrotoxicity involves avoiding substances that can damage the kidneys, as well as managing underlying health conditions that can increase the risk of kidney damage. This may involve:

• Regularly monitoring kidney function
• Using medications as directed
