In SLCO1B3 polymorphism, insertion (ins)/ins, ins/wild, and wild/

In SLCO1B3 polymorphism, insertion (ins)/ins, ins/wild, and wild/wild genotype was present in 2.3%, 20.5%, and 77.3% of the cases, respectively, while in 0.2%, 10.5%, and 89.4% of the controls, respectively. The allele frequency of L1 insertion was 12.5% of the cases, which was significantly greater than the controls

(5.4%, P=0.012, odds ratio 2.5 [95% CI: 1.3-4.9]). The c.1738C>T mutation in SLCO1B1 was not observed in both cases and www.selleckchem.com/products/Deforolimus.html controls. [Conclusions] The genotype of L1 retrotransposon insertion in SLCO1B3 was observed more frequently in Japanese patients with drug-induced cholestasis than controls. As L1 insertion potentially impairs the function of OATP1B3, the individuals with this polymorphism might be predisposed to acquired cholestasis.

Methods: All consecutive PSC patients undergoing liver transplantation in Sweden between 1999 and 2013 were evaluated (n=255). Patients

were categorized using histopathology of the explanted liver to determine the presence

of CCA or dysplasia. Sensitivity, specificity, 上海皓元医药股份有限公司 and other measures of test performance were calculated for single and repeated brush cytology, with or without fluorescence in situ hybridization (FISH). Survival after liver transplantation was analyzed using Kaplan-Meier estimate. Results: Brush cytology was done before liver transplantation in 117 of the 225 patients, of whom 65 patients were brushed more than once. The sensitivity and specificity of brush cytology for diagnosing dysplasia or CCA increased from 50% and 81% respectively in patients with one sampling, to 100% and 83% respectively in patients where repeated examinations were performed (table 1). When considering only the subgroup where FISH was also done in addition to brush cytology (n=64), the presence of aneuploidy increased the sensitivity of brush cytology in this subgroup from 83% to 95%, while the finding of only diploid cells increased specificity from 90% to 95%. Survival after liver transplantation was significantly lower in the group with pre-transplantation undiagnosed CCA in the explanted liver p<0.001). Conclusion: In PSC patients, the utilization of repeated brush cytology or the combination with FISH results in increased sensitivity and specificity for the detection of dysplasia or CCA.
