Hypouricemia and Hyperuricosuria as Expressions of Renal Tubular Damage in Primary Biliary Cirrhosis
Namiki Izumi, Yasushi Hasumura, Jugoro Takeuchi – 1 January 1983 – Renal tubular damage, in particular, renal tubular acidosis is associated with primary biliary cirrhosis (PBC), but hypouricemia has not been described. We studied four patients with PBC whose serum uric acid levels were 1.4 to 1.8 mg per dl, and compared their renal and liver functions with those of 11 patients with PBC whose serum uric acid levels were normal. In the patients with PBC and hypouricemia, uric acid clearance (Cua) and the ratio of Cua and creatinine clearance (Cua/Ccr) were high enough to cause hypouricemia.
