Hipoüriseminin Muhtemel Nedeni; Ksantinüri

Kalıtımsal hipoürisemiye genellikle ksantinüri ve herediter renal hipoürisemi yol açmaktadır. Hipoürisemi serum ürik asit seviyesinin 2mg/dl’den düşük olması olarak tanımlanmaktadır. Ksantinüri her yaşta, nadir görülen ve otozomal resesif geçen bir hatalıktır. Ksantin ve hipoksantin, enzim veya kofaktör eksikliği sonucu ürik asite dönüşümü olmaz ve kanda birikir, ayrıca idrar ile atılımı artar. Serum ve idrarda ürik asit seviyesi çok düşük saptanmaktadır. Biz bu makalede,hipoürisemi saptanan ve ksantinüri tanısı konulan yetmiş yediyaşında kadınhasta litaratüreşliğinde tartışıldı.

Anahtar Kelimeler:

Hipoürisemi, Ksantinüri, böbrek taşı

The Probable Cause of Hypouricemia; Xanthinuria

Xanthinuria and hereditary renal hypouricemia usually leads to hereditary hypouricemia. Hypouricemia is defined as having serum uric acid level lower than 2 ml/dl. Xanthinuria is an autosomal recessive disease that can be occasionally seen in all ages. As a result of enzyme or cofactor deficiency, xanthine and hypoxanthine do not convert to uric acid and accumulate in the blood and increase the excretion in urine. The level of uric acid is detected very low either in serum or in urine. In this study, a case of a seventy-seven-year-old female patient in which hypouricemia was detected and who had the diagnosis of xanthinuria was discussed.
