Why is allopurinol used for tumor lysis syndrome? Medications can be adjusted after the start of chemotherapy in response to the level of tumor lysis and/or metabolic disturbances. Allopurinol, a xanthine oxidase inhibitor, reduces the conversion of nucleic acid byproducts to uric acid, in this way preventing urate nephropathy and subsequent oliguric renal failure.
Why is allopurinol used in cancer patients? Allopurinol can be given at the start of a course of chemotherapy. When chemotherapy medicines start to kill the cancer cells, uric acid is released from these cells which can crystallise causing damage to the kidneys. Allopurinol stops these crystals from forming.
What are interventions for tumor lysis syndrome? Intermediate-risk patients should be offered up to 7 days of allopurinol prophylaxis, along with increased hydration once cancer treatment is initiated, or until risk of tumor lysis syndrome has resolved. High-risk patients should be offered prophylaxis with rasburicase, along with increased hydration.
How does tumor lysis cause hyperuricemia? When cancer cells break down quickly in the body, levels of uric acid, potassium, and phosphorus rise faster than the kidneys can remove them. This causes TLS. Excess phosphorus can “sop up” calcium, leading to low levels of calcium in the blood.

How can down syndrome happen?
Down syndrome is usually caused by an error in cell division called “nondisjunction.” Nondisjunction results in an embryo with three copies of chromosome 21 instead of the usual two. Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separate.
