Background: Invasive fungal disease (IFD) treatment is challenging in hematologic patients due to drug interactions and toxicities that limit the use of the antifungal agents.
Aims: To analyze retrospectively in terms of safety and potential efficacy anidulafungin therapy, alone or in combination.
Methods: Our institutional guidelines recommended anidulafungin treatment in hematologic patients with suspected IFD and concomitant renal or liver impairment (to avoid drug interactions and preserve organ function).
Results: From 2008 to 2013, 24 episodes of IFD occurring in 21 patients were classified as proven (4 cases), probable (15 cases) and possible (5 cases). Anidulafungin was administered alone (13%) or in combination (88%). Eight (33%) episodes were resolved, using monotherapy (1 out of 3, 33%) or a combined therapy (7 out of 21, 33%). Twelve cases (50%) were registered as failure (death due to IFD progression in 4 patients, and treatment change due to lack of efficacy in 8), and 4 cases (17%) were not evaluable (death unrelated to the IFD). Anidulafungin was not withdrawn in any case due to toxicity.
Conclusions: Anidulafungin therapy, alone or in combination, could be considered in hematologic patients with IFD and concomitant liver or renal impairment. Due to the low number of patients, we cannot draw any conclusion about efficacy.

Hematopoietic stem cells (HSCs) possess the capacity to regenerate the entire hematopoietic system. However, the precise HSC dynamics in the early post-transplantation phase remain an enigma. Clinically, the initial hematopoiesis in the post-transplantation period is critical, necessitating strategies to accelerate hematopoietic recovery.

The established protocol for the management of acute myeloid leukemia (AML) has traditionally involved the administration of induction chemotherapy, followed by consolidation chemotherapy, and subsequent allogeneic stem cell transplantation for eligible patients. However, the prognosis for individuals with relapsed and refractory AML remains unfavorable. In response to the necessity for more efficacious therapeutic modalities, targeted immunotherapy has emerged as a promising advancement in AML treatment.

One hallmark of cancer is the upregulation and dependency on glucose metabolism to fuel macromolecule biosynthesis and rapid proliferation. Despite significant pre-clinical effort to exploit this pathway, additional mechanistic insights are necessary to prioritize the diversity of metabolic adaptations upon acute loss of glucose metabolism. Here, we investigated a potent small molecule inhibitor to Class I glucose transporters, KL-11743, using glycolytic leukemia cell lines and patient-based model systems.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Acute B-lymphoblastic leukemia (B-ALL) is a highly heterogeneous hematologic malignancy, characterized by significant molecular differences among patients as the disease progresses. While the PI3K-Akt signaling pathway and metabolic reprogramming are known to play crucial roles in B-ALL, the interactions between lipid metabolism, immune pathways, and drug resistance remain unclear. In this study, we performed multi-omics analysis on different patient cohorts (newly diagnosed, relapsed, standard-risk, and poor-risk) to investigate the molecular characteristics associated with metabolism, signaling pathways, and immune regulation in B-ALL.
