[Factors Influencing and Adverse Reactions of Voriconazole Clearance in Patients with Hematological Diseases]

Abstract

Objective: To monitor the changes of voriconazole minimum concentration(C_min) in patients with hematological diseases, and evaluate the factors influencing and adverse reactions of voriconazole clearance in patients with hematological diseases, so as to provide a theoretical basis for reasonable clinical use of voriconazole.

Methods: 136 patients with hematological diseases who used voriconazole in Wuhan NO.1 Hospital from May 2018 to December 2019 were selected. The correlation between C-reactive protein, albumin, creatinine and voriconazole C_min were analyzed, and the changes of voriconazole C_min after glucocorticoid treatment was also detected. In addition, stratified analysis was used to explore the adverse events of voriconazole.

Results: Among 136 patients, 77 were male (56.62%) and 59 were female (43.38%). There were positive correlations between voriconazole C_min and C-reactive protein and creatinine levels (r=0.277, r=0.208), while voriconazole C_min was negatively correlated with albumin level (r=-2.673). Voriconazole C_min in patients treated with glucocorticoid was decreased significantly (P<0.05). In addition, sratified analysis of voriconazole C_min showed that compared with voriconazole C_min 1.0-5.0 mg/L group, the incidence of adverse reactions of visual impairment in voriconazole C_min> 5.0 mg/L group was increased (χ²=4.318, P=0.038).

Conclusion: The levels of C-reactive protein, albumin and creatinine are closely related to the voriconazole C_min, which indicate that inflammation and hyponutrition may prevent the clearance of voriconazole in patients with hematological diseases. It is necessary to monitor the voriconazole C_min of patients with hematological diseases, and adjust the dosage in time to reduce adverse reactions.
