To evaluate the usefulness of 7 alpha-hydroxy-4-cholesten-3-one (HCO) serum concentrations as a diagnostic marker of bile acid malabsorption, we determined the reference range of HCO in 106 normal subjects (age 40.2 +/- 16.8 years; 55 women, 51 men) and conducted a utility study in 23 patients with chronic diarrhea of unknown origin (age 49.4 +/- 15.3 years, 13 women, 10 men). The diagnosis of bile acid malabsorption was made on the basis of a decreased retention of [Se-75]homocholyltaurine after oral application ((75)SeHCAT test). HCO (reference range: 6-48 ng/ml) and the (75)SeHCAT test yielded the same results in 19/23 (83%) patients. Bile acid malabsorption was identified by an increase of HCO in serum with a sensitivity of 90% and a specificity of 79%. Analysis of HCO in serum may serve as a novel, simple, and sensitive method for the detection of bile acid malabsorption in patients with chronic diarrhea of unknown origin.
