Background: Pulmonary hypertension (PH) has rarely been associated with myeloproliferative neoplasms (MPNs), classified as World Health Organization group 5 PH. Progression of MPN may result in acute myelogenous leukemia (AML).
Case Summary: We describe a young woman with AML arising from MPN presenting with PH. Both the AML and PH were alleviated with pulmonary vasodilators and chemotherapy. The patient eventually underwent allogeneic hematopoietic stem cell transplantation, achieving remission. Several months later, she presented with respiratory symptoms and worsening of PH, signaling the relapse of her AML, subsequently confirmed with right heart catheterization and bone marrow biopsies.
Discussion: Our case highlights the interplay between PH and hematologic malignancies. Literature suggests that PH progression may parallel the progression of MPN.
Take-home Messages: Prompt recognition of PH in those with MPNs is needed to facilitate appropriate interventions in a multidisciplinary manner. Although an association between PH and MPN exists, further studies into the underlying mechanisms and their interplay is needed.

Allogeneic stem cell transplantation (allo-SCT) is a curative option for acute myelogenous leukemia (AML), but relapse is a challenge. Monitoring minimal residual disease post-transplant through detection of tumor-associated circulating cell-free DNA (TA-cfDNA) in peripheral blood (PB) and bone marrow is an emerging strategy to predict relapse. Persistent mutations in TA-cfDNA may be prognostic indicators of relapse and mortality.

The acquired JAK2-V617F mutation plays a causal role in myeloproliferative neoplasms (MPN). Weakly activating JAK2 germline variants have been associated with MPN risk, but the underlying mechanisms remain unclear. We previously identified the JAK2-R1063H germline variant, which contributes to hereditary MPN and increased disease severity in essential thrombocythemia.

Objective: Graft-versus-host disease (GVHD) is the most prevalent long-term complication following allogeneic hematopoietic stem cell transplant (allo-HSCT). This study aimed to investigate specific posttransplant metabolic alterations in allo-HSCT recipients with acute myelogenous leukemia (AML) or myelodysplastic neoplasms (MDS).
Methods: We analyzed the global metabolic profile in serum samples from 37 patients at 3 months posttransplantation.
Background: Ponatinib is a third-generation tyrosine kinase inhibitor (TKI) for treatment of chronic myeloid leukemia (CML) and Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) in patients who fail or are intolerant to a second generation TKI or who carry the mutation.
Method: This is the final analysis of the Belgian ponatinib registry evaluating use of ponatinib in clinical practice, with data available for up to 6 years after reimbursement.
Result: Forty-eight percent of 54 CML and 28% of 29 Ph+ ALL patients had received ≥3 previous TKIs.

BACKGROUND Acute myelogenous leukemia (AML) is a rare, aggressive, disease that requires prolonged treatment. It accounts for a third of all leukemias diagnosed in the United States. A bone marrow biopsy accompanied by histological, cytogenetic, and molecular analysis is essential for the classification of malignancy.
