Abstract
Posaconazole is widely used in lung transplant recipients as pre-emptive therapy or universal fungal prophylaxis. In this patient group, posaconazole is increasingly used instead of voriconazole due to the concerns of an increased risk of squamous cell carcinoma (SCC) with voriconazole, particularly with its long-term use. Dose dependent toxicity has not been identified for posaconazole in the registration trials of intravenous (IV) and modified-release tablet formulations. This is supported by post-marketing experience. We describe a lung transplant recipient who experienced dementia-like symptoms almost 3 years after commencing posaconazole for treatment of Aspergillus fumigatus complex and Lomentospora prolificans (formerly Scedosporium prolificans) fungal infections. Symptoms resolved upon discontinuation of posaconazole, but recurred when re-challenged at a lower dose more than a year later. To the best of our knowledge, this is the first case reporting a dementia-like state with posaconazole.
