Hyperuricaemia or hyperuricemia is an abnormally high level of uric acid in the blood. In the pH conditions of body fluid , uric acid exists largely as urate, the ion form. [ 1 ] [ 2 ] Serum uric acid concentrations greater than 6 mg/dL for females, 7 mg/dL for males, and 5.5 mg/dL for youth (under 18 years old) are defined as hyperuricemia. [ 3 ]
A 2011 survey in the United States indicated that 3.9% of the population had gout, whereas 21.4% had hyperuricemia without having symptoms. [ 43 ] Excess blood uric acid (serum urate) can induce gout , [ 44 ] a painful condition resulting from needle-like crystals of uric acid termed monosodium urate crystals [ 45 ] precipitating in joints ...
Underexcretion of uric acid by the kidney is the primary cause of hyperuricemia in about 90% of cases, while overproduction is the cause in less than 10%. [5] About 10% of people with hyperuricemia develop gout at some point in their lifetimes. [19] The risk, however, varies depending on the degree of hyperuricemia.
Hyperuricosuria is a medical term referring to the presence of excessive amounts of uric acid in the urine. For men this is at a rate greater than 800 mg/day, and for women, 750 mg/day. [1] Notable direct causes of hyperuricosuria are dissolution of uric acid crystals in the kidneys or urinary bladder, and hyperuricemia.
Azotemia (from azot 'nitrogen' and -emia 'blood condition'), also spelled azotaemia, is a medical condition characterized by abnormally high levels of nitrogen-containing compounds (such as urea, creatinine, various body waste compounds, and other nitrogen-rich compounds) in the blood.
Hyperuricemia results from a combination of increased generation and decreased excretion of uric acid, which is generated when increased amounts of G6P are metabolized via the pentose phosphate pathway. It is also a byproduct of purine degradation. Uric acid competes with lactic acid and other organic acids for renal excretion in the urine.
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...
