[2] [4] Another approach to prevent damage to the kidneys is to prevent the buildup of uric acid during TLS, and this can be accomplished with use of allopurinol or rasburicase. [2] Allopurinol (a xanthine oxidase inhibitor, which inhibits uric acid production) works by preventing the formation of uric acid following tumor cell lysis.
Uric acid is a heterocyclic compound of carbon, nitrogen, oxygen, and hydrogen with the formula C 5 H 4 N 4 O 3. It forms ions and salts known as urates and acid urates, such as ammonium acid urate. Uric acid is a product of the metabolic breakdown of purine nucleotides, and it is a normal component of urine. [1]
Lab tests are used to measure the potential of elevated serum concentrations such as uric acid, potassium, phosphate, and hypocalcemia. Disseminated intravascular coagulation and spontaneous tumor lysis syndrome can develop before and after chemotherapy treatment. Patients undergoing this type of therapy need to be closely monitored before and ...
Diagnosis is based on clinical and laboratory findings of low serum osmolality and low serum sodium. [13] Urinalysis reveals a highly concentrated urine with a high fractional excretion of sodium (high sodium urine content compared to the serum sodium). [14] A suspected diagnosis is based on a serum sodium under 138.

Unless high blood levels of uric acid are determined in a clinical laboratory, hyperuricemia may not cause noticeable symptoms in most people. [4] Development of gout – which is a painful, short-term disorder – is the most common consequence of hyperuricemia, which causes deposition of uric acid crystals usually in joints of the extremities, but may also induce formation of kidney stones ...
Hypouricemia or hypouricaemia is a level of uric acid in blood serum that is below normal. In humans, the normal range of this blood component has a lower threshold set variously in the range of 2 mg/dL to 4 mg/dL, while the upper threshold is 530 μmol/L (6 mg/dL) for women and 619 μmol/L (7 mg/dL) for men.

The rapid breakdown of cancer cells causes the release of chemicals from the inside of the cells. Following this, high levels of uric acid, potassium and phosphate are found in the blood. High levels of phosphate induce secondary hypoparathyroidism, resulting in low levels of calcium in the blood. [125]
