A 41-year-old woman with no known immunosuppression experienced a 12-year period of a relapsing phaeohyphomycosis. Despite administration of multiple courses of therapy with standard antifungals, sustained clinical remission was not achieved. A partial response was seen initially with the combination of itraconazole and flucytosine therapy, but the patient did not respond to subsequent treatment. During the patient's pregnancy, the mycosis became disseminated, with lymphadenopathy and fever, and was considered life threatening. Despite receipt of parenteral amphotericin B therapy, the patient did not show a clinical response. After premature delivery by cesarean section, treatment with oral posaconazole suspension (800 mg/day) was started. The patient's condition improved within 1 week after initiating treatment; therapy was continued for 13 months. During posaconazole treatment, the patient showed a complete clinical response, with negative results of fungal cultures.

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.

Objective: To retrospectively analyze the incidence of infections in elderly acute myeloid leukemia (AML) patients undergoing induction therapy with venetoclax combined with hypomethylating agents and to compare these findings with those from patients receiving standard or low-dose chemotherapy.
Methods: Medical records of 169 elderly (≥60 years old) AML patients diagnosed via MICM (morphology, immunology, cytogenetics, and molecular genetics) at the First Affiliated Hospital of USTC between June 2019 and June 2022 were reviewed. Patients were divided into three groups: venetoclax combined with hypomethylating agents group (targeted therapy group), standard chemotherapy group, and low-dose chemotherapy group.

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: BCL-2 was the first gene identified to have antiapoptotic effects, and venetoclax is an oral selective BCL-2 inhibitor, which has great potential in the treatment of patients with acute myeloid leukemia (AML) who are not candidates for intensive therapy. Notably, posaconazole, an oral antifungal drug, is also a strong factor that can affect blood venetoclax concentrations. To the best of our knowledge, the relationship between BCL-2 expression, posaconazole, and venetoclax, as well as their influence on treatment efficacy and the prognosis of patients with AML, has not been reported.

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.
