Bile salt transport in the Dubin-Johnson syndrome.

Abstract
Serum bile salt measurements and i.v. clearance of glycocholate were performed in a woman with Dubin-Johnson syndrome. Fasting conjugated cholate concentration was raised and prolonged i.v. clearance of sodium glycocholate revealed a secondary rise in conjugated cholate concentration after 2 h. The i.v. clearance of bromsulphthalein also showed a secondary rise. Dubin-Johnson syndrome is apparently not homogeneous and in some patients an abnormality of bile salt clearance apparently coexists with an abnormality of bilirubin and bromsulphthalein clearance.
