Nephrotoxicity

Nephrotoxicity means damage to the kidneys caused by a drug, chemical, or other substance. It can show up as reduced kidney function on blood tests (rising creatinine, falling eGFR), protein or blood in the urine, or, in severe cases, acute kidney injury requiring hospitalization. The damage may be temporary and reversible, or it may progress to chronic kidney disease.

Origin

From the Greek nephros (kidney) and toxikon (poison). The term entered medical use in the late 19th and early 20th centuries as pharmacology began systematically describing organ-specific drug toxicities.

Significance in Asbestos Context

For patients with mesothelioma or other asbestos-related cancers, nephrotoxicity is most often a concern as a side effect of treatment rather than a direct effect of asbestos itself. Cisplatin, a backbone chemotherapy drug in mesothelioma regimens (often paired with pemetrexed), is well known for damaging the kidneys, and pemetrexed itself is cleared by the kidneys and can be unsafe if kidney function drops. Some pain medications (NSAIDs), contrast dye used in CT scans, and certain antibiotics add further risk. Kidney function therefore drives real treatment decisions: whether you can receive full-dose chemotherapy, whether doses must be reduced, whether scans can use IV contrast, and whether you qualify for certain clinical trials.

Example Sentence

Before each cycle of cisplatin and pemetrexed, the oncology team checked her creatinine and eGFR to watch for nephrotoxicity that might require a dose reduction.

Notes

• Ask your oncologist which of your medications and scans carry kidney risk, and what eGFR or creatinine threshold would cause them to change your treatment plan.
• Stay well hydrated around chemotherapy and contrast-enhanced scans unless your doctors tell you otherwise; IV fluids before and after cisplatin are standard to protect the kidneys.
• Avoid routine use of NSAIDs (ibuprofen, naproxen) during chemotherapy without checking with your oncologist, since they can compound kidney injury.
• Keep copies of all kidney function labs (BUN, creatinine, eGFR, urinalysis). Declining kidney function during treatment is part of the medical record that documents the burden of your illness and may be relevant to damages in a legal claim.
• Tell every new provider (dentist, ER, specialists) about your cancer treatment so they avoid prescribing additional nephrotoxic drugs.
