Pharmacokinetic data from a randomized, parallel-group, multicenter study are presented. Adults with toenail onychomycosis (n = 146) received posaconazole (100 mg, 200 mg, or 400 mg) once daily (QD) for 24 weeks or 400 mg QD for 12 weeks. The posaconazole concentration in the great toenail exhibited a dose-related increase starting at week 2 for 24 weeks and a mean toenail-to-plasma concentration ratio of approximately 3:1 at the end of treatment for the 400-mg 24-week dose.

A simple, fast, sample-saving, and sensitive liquid chromatography-tandem mass spectrometry method was established with a linear range adjusted by in-source collision-induced dissociation. Notably, this could simultaneously determine busulfan, fludarabine, phenytoin, and posaconazole in plasma from children, each having unique physical and chemical properties. The procedure necessitated only 20 μL of plasma and involved a simple protein precipitation process.

Introduction: Posaconazole is recommended for prophylaxis in pediatric immunocompromised patients. Due to its variability in bioavailability and drug-to-drug interactions, EBMT recommends regimens based on therapeutic drug monitoring (TDM).
Materials And Methods: In total, 171 oncohematological pediatric patients on posaconazole prophylaxis were included.
Venetoclax plus azacitidine represents a key advance for older, unfit patients with acute myeloid leukemia (AML). The chemotherapy and venetoclax in elderly AML trial (CAVEAT) was first to combine venetoclax with intensive chemotherapy in newly diagnosed patients ≥65 years. In this final analysis, 85 patients (median age 71 years) were followed for a median of 41.

Background: This study investigated the impact of posaconazole (POSA) prophylaxis in COVID-19 patients with acute respiratory failure receiving systemic corticosteroids on the risk for the development of COVID-19-associated pulmonary aspergillosis (CAPA).
Methods: The primary aim of this prospective, multicentre, case-control study was to assess whether application of POSA prophylaxis in mechanically ventilated COVID-19 patients reduces the risk for CAPA development. All consecutive patients from centre 1 (cases) who received POSA prophylaxis as standard-of-care were matched to one subject from centre 2 and centre 3 who did not receive any antifungal prophylaxis, using propensity score matching for the following variables: (i) age, (ii) sex, (iii) treatment with tocilizumab and (iv) time at risk.

Background: Mucormycosis is an opportunistic fungal infection which is associated with poor prognosis. Only a few antifungals are available in the arsenal against mucormycosis. The global guidelines for diagnosing and managing mucormycosis recommend high doses of liposomal amphotericin B (LAmB) as the first-line treatment.
