1Thiopurine-methyltransferase variants in inflammatory bowel disease:Prevalence and toxicity in Brazilian patients显示文摘AIM:To analyze the prevalence of thiopurine-methyltransferase(TPMT)genotypes and their associationwith drug toxicity in inflammatory bowel disease(IBD)patients from southeastern Brazil.METHODS:A total of 219 consecutive patients with IBD,of which 146 had Crohn’s disease and 73 had ulcerative colitis,regularly seen at the outpatient unit of the Division of Gastroenterology at the University Hospital Pedro Ernesto of the State University of Rio de Janeiro,a tertiary referral center,were enrolled in this study from February 2009 to January 2011.We analyzed the presence of major TPMT genetic variants(TPMT*2,*3A,*3C)in IBD patients by means of a specific allele and RFLP-PCR.Genomic DNA was isolated from peripheral blood leukocytes by proteinase-K/Sodium Dodecyl Sulfate digestion and phenol-chloroform extraction.TPMT*2(C238G),TPMT*3A(G460A/A719G),and TPMT*3C(A719G)genotypes were detected by real-time polymerase chain reaction followed by direct sequencing with specific primers.Clinical data were systematically recorded,and correlated with the genotype results.RESULTS:The distribution of the selected TPMT gene polymorphism TPMT*2(C238G),TPMT*3A(G460A/A719G),and TPMT*3C(A719G)genotypes was 3.6%,5.4%,and 7.7%of the patients,respectively.Among the side effects recorded from patients taking azathioprine,14 patients presented with pancreatitis and/or an elevation of pancreatic enzymes,while 6 patients had liver toxicity,and 2 patients exhibited myelosuppression/neutropenia.TPMT polymorphisms were detected in 37/219 patients(8 heterozygous for*2,11 heterozygous for*3A,and 18 heterozygous for*3C).No homozygotic polymorphisms were found.Despite the prevalence of the TPMT*3C genotype,no differences among the genotype frequencies were significant.Although no association was detected regarding myelotoxicity or hepatotoxicity,a trend towards the elevation of pancreatic enzymes was observed for TPMT*2 and TPMT*3C genotypes.CONCLUSION:The prevalence of TPMT genotypes was high among Brazilian patients.Variants genes*2and*3C may be associated with azathioprine pancreatic toxicity in a IBD southeastern Brazilian population.Ana Teresa P Carvalho Barbara C Esberard Renata S B Fróes Davy C M Rapozo Ana B Grinman Tatiana A Simo Juliana C V C Santos Antonio José V Carneiro Luis Felipe Ribeiro-Pinto Heitor S P de Souza 2014World Journal of Gastroenterology2014,20,12:3
