...COMPETITION FOR EXTRAVASCULAR BINDING SITES BY DEOXYCHOLIC ACID MAY EXPLAIN REDUCED VOL OF DISTRIBUTION OF BROMSULFOPHTHALEIN IN PRESENCE OF BILE ACID.
Deoxycholic acid was tested alone and as a promoter of N-nitrosobis(2-hydroxypropyl)amine induced carcinogenesis in the hamster. Three groups of 5 to 6-wk-old male Syrian hamsters (SYR)/NI were used and 10 animals per group were given subcutaneous injections of 0.9% NaCl, once per week for 5 weeks. Group 1 received no further treatment; groups 2 and 3 received 0.1% and 0.5% DCA in their feed for 30 weeks, respectively. Animals were autopsied at week 35. There was no significant difference in body wt. between groups 1 and 2, whereas there was a significant decrease in body weight for group 3 (P<0.005). There were no liver tumors, bile duct proliferation, gallbladder lesions or polyps, pancreatic lesions, or pancreatic duct hyperplasia in these 3 groups. In the promoter study, three groups of 5 to 6-wk-old hamsters (number not stated) were given a subcutaneous injection of 500 mg/kg body wt. N-nitrosobis(2-hydroxypropyl)amine per week for 5 weeks. Group 4 received no further treatment and the N-nitrosobis(2-hydroxypropyl)amine treatment was followed by 0.1% DCA (group 5) , or 0.5% DCA (group 6) in the feed for 30 weeks. There was a significant body weight loss (P<0.005) for groups 5 and 6 compared to group 4. DCA significantly increased the induction of cholangiocarcinomas 10/19 in group 5 (P<0.006); 9/25 in group 6 (P<0.05) compared to group 4 which had 1/15. Pancreatic carcinomas were significantly increased in group 5 (14/19, P<0.03). Therefore, under the conditions of this experiment, DCA was not carcinogenic when given alone but was an effective promoter of N-nitrosobis(2-hydroxypropyl)amine-induced hepatic and pancreatic carcinogenesis in hamsters.
Deoxycholic acid is rapidly absorbed after subcutaneous administration. After maximum recommended single treatment dose, 100mg, the post-treatment plasma levels returned to endogenous levels within 24 hours. With the proposed treatment guideline, no accumulation is expected.
The exogenous deoxycholic acid joins the endogenous bile acid pool in the enterohepatic circulation and is excreted unchanged in feces along with endogenous deoxycholic acid.
