Adverse Effects Associated with Long-Term Administration of Azole Antifungal Agents

AbstractAzole antifungals are first-line options in the prophylaxis and treatment of invasive fungal infections. They are often used for prolonged (weeks to months) periods of time, particularly in patients with hematologic malignancies, or in those who have received a solid organ or hematopoietic stem cell transplant. Long-term use of azoles is associated with hepatotoxicity and hormone-related effects, including gynecomastia, alopecia, decreased libido, oligospermia, azoospermia, impotence, hypokalemia, hyponatremia, and (rarely) adrenal insufficiency. Voriconazole and posaconazole have been associated with peripheral neuropathies, and itraconazole and voriconazole with pancreatitis. In addition, voriconazole has been associated with periostitis, phototoxic reactions, and squamous cell carcinoma. Since many at-risk patients are commonly receiving multiple medications, it can be difficult for care providers to identify antifungal agent causality or contribution to patient symptoms. Knowledge and recognition of adverse events caused by azoles, leading to dose reduction or discontinuation, can generally reverse these adverse events.

This article mentions key results that lead to a new perspective where cancer stem cells are primarily seen as cells exhibiting increased epigenetic plasticity and increased gene expression variability. This perspective suggests new therapeutical interventions consisting in stabilizing gene expression to control cancer cell proliferation and prevent stochastic gene expression variations that could lead to therapeutic resistance.

This study revealed the possible occurrence and recurrence risk factors of ovarian endometriosis malignancy using univariate and multivariate statistics analyses. What are the implications of these findings for clinical practice and/or further research? A clinical retrospective study with a longer follow-up period is suggested for assessing the occurrence and recurrence risk factors for ovarian endometriosis malignancies.

Authors: Houédé N Abstract To date, systemic treatments, including hormone therapies or chemotherapy, are used at different stages of prostate cancer disease. Several types of complications can occur during systemic treatment in prostate cancer, depending on the therapeutic range. The most common with hormone therapy are fatigue, muscle loss, bone loss, high blood pressure and metabolic syndromes. For chemotherapy, the most significant risk is related to hematological toxicity, but peripheral neuropathies, mucositis, diarrhea and hypersensitivity reactions may also occur. The quality of the pre-treatm...
