Abstract:
:Tacrolimus, a relatively new therapeutic option for patients with corticosteroid-refractory Crohn's disease or ulcerative colitis, is a substrate for the apically directed efflux transporter P-glycoprotein (P-gp). Duodenal biopsy specimens obtained from a patient with corticosteroid-refractory Crohn's disease and with significantly higher-than-average tacrolimus dose requirements were analyzed for P-gp by Western blot. The P-gp content in this patient was more than double that in specimens obtained from 9 of 10 healthy subjects. Elevated intestinal P-gp could have resulted in decreased tacrolimus absorption, thereby leading to decreased blood concentration and decreased efficacy in this patient. The cause and prevalence of this phenomenon are unknown.
