Common_Name2,8-Dihydroxyadenine
Description2,8-Dihydroxyadenine is a Purine metabolite usually not detectable in biofluids of normal individuals; this insoluble metabolite (at physiological urinary pH) cause urinary tract calculi and arthritis, and is identified in Adenine phosphoribosyltransferase deficiency (APRT, OMIM 102600). (PMID 16613999) In APRT, 2,8-dihydroxyadenine (DHA) accumulates in crystals within the tubular lumens (a feature of many kidney stone diseases) creating crystal-induced injury in human kidney epithelial cells. (PMID 16374038) Urinary DHA crystals are easily recognized under a microscope, and effective treatment can be offered and therefore the prognosis depends upon the renal function at diagnosis; treatment consists of adequate fluid intake, a low-purine diet and administration of allopurinol.
