Capillary gas chromatographic determinations of urinary bile acids and bile alcohols in CTX patients proving the ineffectivity of ursodeoxycholic acid treatment

Urine samples and serum samples of a patient with cerebrotendinous xanthomatosis (CTX) were investigated by means of capillary gas chromatography, both before and during oral treatment with ursodeoxycholic acid (UDCA), and the results compared with those obtained during chenodeoxycholic acid (CDCA)...

Zusammenfassung:Urine samples and serum samples of a patient with cerebrotendinous xanthomatosis (CTX) were investigated by means of capillary gas chromatography, both before and during oral treatment with ursodeoxycholic acid (UDCA), and the results compared with those obtained during chenodeoxycholic acid (CDCA) therapy. The predominantly excreted bile alcohol, 5β-cholestane-3α,7α,12α,23,25-pentol and two abnormal bile acids, i.e. 23-norcholic acid and 23-hydroxycholic acid were determined. In addition, the serum cholestanol/cholesterol ratio was determined. Whereas previous experiments demonstrated that the urinary excretion of 5β-cholestane-3α, 7α,12α,23,25-pentol and the abnormal bile acids decreased within a few weeks during CDCA therapy, the present study shows that their urinary excretions remain essentially the same during UDCA treatment. In contrast to the decrease in the serum cholestanol/cholesterol ratio during CDCA therapy, this ratio remains essentially the same during UDCA therapy. It is therefore concluded that, in contrast to CDCA therapy, UDCA treatment is not effective in the treatment of CTX.
