The aim of this study was to investigate the effects of genetic polymorphisms on the posaconazole plasma concentration (PPC). This prospective study was conducted from September 2014 to August 2016. We enrolled patients with acute myeloid leukemia or myelodysplastic syndrome treated with posaconazole oral suspension (200 mg) three times daily for fungal prophylaxis. The patients were examined for the multidrug resistance gene 1 3435C&gt;T and 2677G&gt;T\/A variations and the UGT1A4*3 allele by direct sequencing of DNA from peripheral whole-blood samples. We defined poor absorbers to be those with PPCs of &lt;200 ng\/ml and the optimal PPC to be \u2265700 ng\/ml on day 8. The associations between genetic polymorphisms and the PPC were evaluated using multivariate logistic regression analysis including clinical variables. During the study period, 132 patients were enrolled. Six patients (4.5%) were defined as poor absorbers, and 49 patients (37.1%) did not reach the optimal PPC on day 8. In multivariate analysis, the independent risk factors for a poor absorber were at least one UGT1A4*3 allele (adjusted odds ratio [aOR], 18.81; 95% confidence interval [CI], 1.09 to 324.44;\n            <jats:italic>P<\/jats:italic>\n            = 0.043) and poor oral food intake (aOR per \u2212100 kcal, 1.44; 95% CI, 1.04 to 1.99;\n            <jats:italic>P<\/jats:italic>\n            = 0.029). There was no statistically significant association between the genetic polymorphisms and achievement of the optimal PPC on day 8. The UGT1A4*3 polymorphism is an independent risk factor for being a poor absorber of posaconazole oral suspension in patients with hematological malignancies.\n
