[Abstract]:Objective: to investigate the correlation between the predicted dose of warfarin IWPC and the actual dose. Methods: 97 patients with warfarin gene were selected from a hospital from November 2014 to August 2015, and their basic information and clinical drug use were recorded. The genotypes of CYP2C9O2KORGA-3 and VKORC1 were detected by gene sequencing. The IWPC formula was used to predict the warfarin dose and the correlation between the predicted dose and the actual dose was investigated. Results: 73 of 97 patients who took warfarin were treated with warfarin. The actual initial dose of CYP2C9 / 3 AAVKORC1 AA in the predicted dose range was 81.13% (43 / 53 cases), and the actual initial dose of CYP2C9 / ACVKORC1 AA was 62.50% (58 / 8) within the predicted dose range, and the actual initial dose of the remaining genotypes was in the pre-dose range of 62.50% (58 cases). The ratio within the range of the measured dose is small. In the maintenance dose, the average value of the predicted weekly dose was 19.286 mg, and the average of the actual maintenance weekly dose was 19.958 mg / min. The predicted weekly maintenance dose was not significantly different from the actual maintenance weekly dose. The correlation coefficients between predicted dose and actual dose in VKORC1 AA / CYP2C9 / 3 AC and VKORC1 AGR / CYP2C9 / 3 AA2 groups were 0.537 and 0.916, respectively. Conclusion: the prediction of warfarin dosage by gene detection has some accuracy. In the initial dose prediction, CYP2C9 / VKORC1 AA and CYP2C9 / 3AC / VKORCAA type are higher than that in maintenance dose prediction, and the accuracy of CYP2C9 / VKORCAA and CYP2C93AAVKORC1 AG prediction is higher than that of CYP2C93ACVKORCAA and CYP2C93AAKORC1 AG. It has high clinical reference significance.
