Hyperlipidemia Caused by Voriconazole: A Case Report

Voriconazole has been widely used in clinical practice for nearly 20 years. The adverse reactions caused by voriconazole have been reported gradually, such as visual impairment, hepatotoxicity, skin rash. At present, there are few reports about triazole antifungal drugs causing the increase of triglyceride and total cholesterol. Thus, the present study reported a case of chronic pulmonary aspergillosis with significantly increased blood lipids after treatment with voriconazole. In this case, the patient’s total cholesterol was normal, and triglyceride was 2.64 times of the upper limit of the reference value at the time of admission. On the 30th day after oral administration of voriconazole 200mg q12h, triglyceride and total cholesterol were 4.55 times and 3.31 times of the baseline levels, respectively, with the trough concentration of voriconazole of 6.6 μ g/mL. After 28 days of voriconazole withdrawal and itraconazole administration, triglyceride decreased to 1.45 times of baseline level and total cholesterol decreased to the normal range. After another 24 days of treatment with voriconazole 200mg q12h, triglyceride increased again to 3.25 times of the baseline level and cholesterol was within the normal range. At the same time, the trough concentration of voriconazole was 3.2 μ g/mL. After 14 days of treatment with voriconazole 100mg q12h, the triglyceride level recovered to the baseline level, with the trough concentration of voriconazole of 1.5 μ g/mL. The Naranjo′s rating scale was used, the final score was 10 points, indicating that the causal relationship between voriconazole and dyslipidemia was positive, which was likely to be related to the trough concentration of voriconazole.
