Crizotinib is a medication used to treat certain types of cancer, particularly non-small cell lung cancer (NSCLC) that has specific genetic mutations (like ALK and ROS1). It works by blocking certain proteins that help cancer cells grow.
Acute Kidney Injury (AKI) refers to a sudden decrease in kidney function. It can happen in a matter of hours or days and can be caused by various factors, including medications, dehydration, and infections.
Crizotinib can lead to AKI in some patients. The exact mechanism isn’t fully understood, but it may involve direct damage to kidney cells, dehydration, or effects on blood flow to the kidneys.
Pathophysiology
- Structure of the Kidneys:
- The kidneys are two bean-shaped organs located in the lower back. They filter waste from the blood, balance fluids, and regulate electrolytes.
- Blood Supply:
- Each kidney receives blood through the renal artery, which branches off from the aorta. Blood flows through smaller arteries into the nephrons, the functional units of the kidney.
- Nerve Supply:
- The kidneys have a rich nerve supply that helps regulate their functions, including blood flow and filtration.
Types of Acute Kidney Injury
- Prerenal AKI: Caused by reduced blood flow to the kidneys (e.g., dehydration, heart failure).
- Intrinsic AKI: Caused by direct damage to the kidney tissue (e.g., from medications like Crizotinib).
- Postrenal AKI: Caused by blockage of urine flow (e.g., kidney stones).

- Increased blood levels of Crizotinib
- Rapid tumor lysis syndrome
- Diabetes
- High blood pressure
- Older age
- Previous kidney disease

- Seeking emotional support
- Limiting processed food intake
- Incorporating kidney-friendly foods (berries, leafy greens)
- Utilizing telehealth services for regular monitoring
Drugs for AKI Management
- Crizotinib (with caution)
- Diuretics (to help with fluid balance)
- ACE inhibitors (to lower blood pressure)
- Beta-blockers (for heart health)
- Erythropoietin (to stimulate red blood cell production)
- Phosphate binders (to manage electrolyte levels)
- Calcium supplements (if needed)
- Sodium bicarbonate (to manage acidosis)
- Potassium binders (to lower potassium levels)
- Antibiotics (for infections)
- Steroids (for inflammation)
- Vasopressors (to improve blood flow)
- Antihypertensives (to control high blood pressure)
- Nutritional supplements (if needed)
- Anticoagulants (for blood clots)
- Antidepressants (for mental well-being)
- Anticonvulsants (if seizures occur)
- Analgesics (for pain relief)
- Antiemetics (for nausea)
- Antihistamines (for allergic reactions)
Surgical Options for Severe AKI
- Hemodialysis (to filter blood)
- Peritoneal dialysis (alternative dialysis method)
- Kidney transplant (if kidneys fail)
- Ureteral stenting (to relieve urine blockage)
- Nephrectomy (removal of a kidney)
- Kidney biopsy (to diagnose underlying issues)
- Vascular access surgery (for dialysis)
- Exploratory laparotomy (to check for internal issues)
- Treatment for kidney stones (e.g., lithotripsy)
- Surgery for tumors obstructing kidneys
Preventive Measures for AKI
- Stay well-hydrated
