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 ]
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.
HUPRA syndrome. Other names. Hyperuricemia-pulmonary hypertension-renal failure-alkalosis syndrome. HUPRA syndrome is inherited via autosomal recessive manner. Frequency. Less than one in a million. HUPRA syndrome is a rare syndrome that was first described in 2010 in two infants of Palestinian origin from the same village in the Jerusalem area ...
Hypouricemia. 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. [ 1]
About 10% of people with hyperuricemia develop gout at some point in their lifetimes. [21] The risk, however, varies depending on the degree of hyperuricemia. When levels are between 415 and 530 μmol/L (7 and 8.9 mg/dL), the risk is 0.5% per year, while in those with a level greater than 535 μmol/L (9 mg/dL), the risk is 4.5% per year.
Uremia is the term for high levels of urea in the blood. Urea is one of the primary components of urine. It can be defined as an excess in the blood of amino acid and protein metabolism end products, such as urea and creatinine, which would be normally excreted in the urine. Uremic syndrome can be defined as the terminal clinical manifestation ...
Frequency. 1 in 100,000 live births. Glycogen storage disease type I ( GSD I) is an inherited disease that prevents the liver from properly breaking down stored glycogen, which is necessary to maintain adequate blood sugar levels. GSD I is divided into two main types, GSD Ia and GSD Ib, which differ in cause, presentation, and treatment.
Hyperuricemia (serum uric acid concentration of >8 mg/dL) is often present but not reliable enough for diagnosis. Activity of the HGPRT enzyme in cells from any type of tissue (e.g., blood , cultured fibroblasts , or lymphoblasts ) that is less than 1.5% of normal enzyme activity confirms the diagnosis of Lesch–Nyhan syndrome.
