The hepatic excretion of 131I-rose bengal and 99mTc-IDA derivatives in Rotor's syndrome

G Galli et al. Eur J Nucl Med. 1982.

Abstract

Bilirubin kinetics and hepatobiliary excretion of some exogenous anions (BSP, 131I-rose bengal, diethyl and parabutly-IDA labeled with 99mTc) were studied in three patients presenting with Rotor's syndrome. Two were brothers; a nonjaundiced fraternal twin of one of them was also evaluated. The hepatic clearance of the radiopharmaceuticals was impaired in the affected patients but the degree of impairment was different among the tested anions, i.e., maximal for 99mTc-diethyl-IDA and minimal for 131I-rose bengal. Parabutyl-IDA was cleared better than the diethyl derivative. The metabolic derangement seems to be at the level of transfer from plasma to liver and of the hepatic storage, rather than at the level of hepatocyte excretory pathways, as in the case of Dubin-Johnson syndrome.
