Epidemiology. Xanthine is an intermediate in the degradation of adenosine monophosphate to uric acid, being formed by oxidation of hypoxanthine. Allopurinol may cause side effects. The loss of xanthine dehydrogenase activity prevents the conversion of xanthine to uric acid, leading to an accumulation of xanthine in the kidneys and other tissues. An association between caffeine intake and increased miscarriage risk, and possibly fetal demise has been reported but remains unproven. Because the solubility of xanthine is relatively independent of urinary pH, urine alkalinization has no effect (in contrast to patients with uric acid lithiasis) 12). These enzymes catalyze the oxidation of hypoxanthine to xanthine and can further catalyze the oxidation of xanthine to uric acid.These enzymes play an important role in the catabolism of purines in some species, including humans. This includes prescription medicines, herbal drugs, and nutraceuticals. Rothman, E.M. Mikkelsen, S.B. Drugs. About 150 cases of this condition have been reported in the medical literature.
