title: Effect of thiazide treatment on biliary lipid composition in healthy volunteers.
abstract: An increased incidence of cholecystitis has been observed in thiazide-treated patients. In order to test the possibility that the therapy might have caused an increase in the cholesterol saturation of gallbladder bile, biliary lipid composition was determined in fasting duodenal bile obtained from 10 healthy individuals after cholecystokinin injection, before and after 3 weeks of treatment with hydrochlorthiazide. The mean relative concentration of cholesterol was increased in 6 subjects, from 4.7 to 5.6 mol%, and the cholesterol saturation of bile was increased in 7, from 69 to 81%. These preliminary results indicate that thiazide treatment may to some extent increase biliary cholesterol saturation, and this may, at least in part, explain the higher prevalence of symptomatic gallbladder disease during such therapy.
