| 主な結果/Results | The NUDT15 C/C, C/T, and T/T genotypes were 80.7, 18.2, and 1.1%, respectively.The allelic frequency was 10.2%. Among 161 IBD patients, there was no significant difference in 6-TGN levels among the NUDT15 genotypes.Forty-five patients (27.9%) developed leukocytopenia (WBC<3000/ul), and the C/T and T/T genotypes were significantly associated with the development of leukocytopenia (P=1.7 X 10(-5)). )). In these patients, 6-TGN levels were not significantly different between NUDT15 genotypes. NUDT15 R139C was significantly associated with early (<8 weeks) (P = 1.03 X 10(-4)) and late (>8 weeks) leukocytopenia (P = 4.3 X 10(-4)). The decrease in WBC count at 2 and 4 weeks was significantly higher in patients with the C/T or T/T genotypes as compared to the patients with the C/C genotype. All patients with the T/T genotype (n = 2) developed early severe hair loss and severe leukocytopenia (<1000/ul). The logistic regression analysis revealed that NUDT15 R139C was the sole genetic factor responsible for the thiopurine-induced leukocytopenia (P = 0.001). | |
