It is interesting to consider that some of these compounds are very stable, e.g. 1. Lancet. Primary gout is an arthritis characterized by a derangement of purine metabolism, occurring mostly in males, with the elevation of serum uric acid concentration. Metabolism and action of purine nucleoside analogs. Mayazawe. Multiple systems are affected by disorders of purine and pyrimidine metabolism and as a result the differential diagnosis for these conditions is lengthy. Purine also gives its name to the wider class of molecules, purines, which include substituted purines and their tautomers. Some of the diseases are: Severe immunodeficiency by loss of adenosine deaminase. Most disorders of purine metabolism are expressed by a considerable variation in serum urate concentration and urinary uric acid excretion, since uric acid is the final product of purine metabolism in human beings (see Fig. Presentation PDF Available. Abnormal purine metabolism and purine overproduction in a patient deficient in purine nucleoside phosphorylase. GOUT (Gouty Arthritis): A defect of purine metabolism Serum Uric Acid Levels (mg/dl) Incidence of Gout (% of cases) >9.0 ~10% 7-9 0.5-3.5% <7.0 0.1% Guanine Xanthine Hypoxanthine Urate xanthine oxidase xanthine oxidase Allopurinol: a. decrease urate b. increase xanthine & hypoxanthine c. decrease PRPP.

Rosa Torres Jiménez, Juan García Puig, in Gout & Other Crystal Arthropathies, 2012. 578-594. Purine and pyrimidine metabolism was compared in erythrocytes from three patients from two families with purine nucleoside phosphorylase deficiency and T-cell immunodeficiency, one heterozygote subject for this enzyme deficiency, one patient with a complete deficiency of hypoxanthine-guanine phosphoribosyltransferase, and two normal subjects.
