Hypouricemia by Defect in the Tubular Reabsorption

Open publisher page 32 citations
Abstract
Two patients with hypouricemia with high levels of uric acid in their urine were given pyrazinamide and probenecid. The uric acid clearance decreased to low or normal values after pyrazinamide administration. In both cases, probenecid produced a slight increment in the uric acid excretion. This type of response suggests a defect in the reabsorption component. It is tempting to speculate on a postsecretory reabsorption defect based on the results of pyrazinamide and probenecid tests.
