Abstract

BACKGROUND/AIMS:

Abnormalities of biliary drainage have been documented at hepatobiliary scintigraphy in many but not all patients studied with cystic fibrosis-associated liver disease. Ursodeoxycholic acid was shown to be beneficial in this disease, mainly by improving biliary secretion. Therefore, patients with impaired biliary drainage are expected to obtain the greatest benefit from this treatment.

METHODS:

We evaluated the effects of long-term treatment with ursodeoxycholic acid in 36 patients with cystic fibrosis-associated liver disease, and compared the response in patients presenting a normal (n=18) or delayed time of intestinal visualization (n=18) at baseline hepatobiliary scintigraphy.

RESULTS:

The mean treatment duration was 58+/-26 (S.D.) months and 63+/-29 months in the groups with normal or delayed time of intestinal visualization, respectively. The time of intestinal visualization decreased (57+/-23%, p<0.001) from baseline in patients with initially abnormal values and became normal in four (22%). Treatment failure, i.e. lack of sustained normalization of serum liver enzymes or the occurrence of a clinically relevant adverse event, was more frequently observed in patients with a normal time of intestinal visualization at baseline (OR, 5.50; 95% CI, 1.32-22.7). When only clinically relevant adverse events were considered, they occurred in six of the latter patients (liver transplantation in one case, development of ultrasographic or endoscopic signs of portal hypertension in six cases), but in only one patient (development of portal hypertension) in the group with delayed time of intestinal visualization (OR, 10.82; 95% CI, 1.17-100.4).

CONCLUSIONS:

Delayed intestinal visualization at hepatobiliary scintigraphy in patients with cystic fibrosis-associated liver disease seems to predict a better response to ursodeoxycholic acid.
