%X BACKGROUND: Mucormycosis presents a diagnostic challenge characterized by high morbidity and mortality rates due to its swift and pervasive nature, which leads to extensive tissue destruction and dissemination. Immunocompromised individuals, notably those with hematological malignancies, are at a heightened risk. First-line antifungal agents include liposomal amphotericin B (L-AMB), posaconazole, and isavuconazole (IVZ), which offer advantages, such as minimal drug interactions and a favorable safety profile. However, the necessity and efficacy of therapeutic drug monitoring (TDM) of IVZ remain unclear.
METHODS: We report a successful case of IVZ therapy in a patient who was intolerant of L-AMB, highlighting the efficacy and pharmacokinetics of IVZ in treating pulmonary mucormycosis. Pharmacokinetic analysis revealed steady plasma IVZ concentrations, emphasizing the importance of monitoring IVZ levels, particularly in patients undergoing renal replacement therapy.
CONCLUSIONS: This case highlights the efficacy of IVZ therapy for mucormycosis and the potential utility of TDM in a specific patient population. Further research is needed to elucidate the optimal IVZ dosing and monitoring strategies to ensure safe and efficacious treatment.
