The occurrence of acute myelogenous leukemia (AML) in HIV-infected patients is extremely rare with only adult patients reported so far. Our patient was a 7-year-old male who presented with fever and cough since 1 month with six episodes of intermittent hemoptysis. The child also had recurrent parotid swellings, melena, and purulent otitis media. Investigations revealed anemia (hemoglobin of 8.9 g/dl), thrombocytopenia (platelet count of 21,000 cells per microliter), and positive HIV antibody (perinatal transmission). The patient's bone marrow aspiration and biopsy suggested AML, and the leukemia panel 1 study showed CD13, CD33, CD34, and HLA DR-positive AML with CD7 expression. The child was given supportive treatment but succumbed to the disease. AML can occur in pediatric patients with HIV infection. A high index of suspicion of hematological malignancies should be kept in mind for patients presenting with cytopenias. This is the first HIV-infected pediatric patient (<12 years) with AML reported in the medical literature.

The outcomes of cardiac surgery in patients with hematologic disorders are significantly worse. However, details of the clinical course of each hematologic disease remain unclear. Myelodysplastic syndrome (MDS) presents with progressive pancytopenia that has the risk of infection, hemorrhage, and transformation to acute myelogenous leukemia.

FLT3-ITD and TKD mutants play a central role in acute myeloid leukemia (AML), making FLT3 an attractive target for AML treatment. To discover next-generation FLT3 inhibitors and gather additional structure-activity relationship (SAR) information, we performed structural modifications of G-749 (denfivontinib) utilizing structure simplification and scaffold hopping strategies. Among these derivatives, MY-10 exhibited the most potent and selective inhibition of MV4-11 cell proliferation, demonstrating potent inhibitory activity against FLT3-ITD (IC = 6.

Homeobox (HOX) transcript antisense RNA (HOTAIR) and HOX genes are reported to be more expressed in various cancers in humans in recent studies. The role of HOTAIR and HOXD genes in acute myeloid leukemia (AML) and chronic myeloid leukemia (CML) is not well known. In this study, expression levels of HOXD8, HOXD9 and HOXD11 from HOXD gene family and HOTAIR were determined from peripheral blood samples of 30 AML and 30 CML patients and 20 healthy volunteers by quantitative Real Time PCR.

MicroRNAs (miRNAs) emerge as critical regulators of CD8 + T cell function within the complex tumor microenvironment (TME). This review explores the multifaceted interplay between miRNAs and CD8 + T cells across various cancers. We discuss how specific miRNAs influence CD8 + T cell activation, recruitment, infiltration, and effector function.

Background: Acute myelogenous leukemia (AML) is a type of blood cancer that is characterized by the accumulation of young and undeveloped myeloid cells in the bone marrow. It is considered a heterogeneous disease due to its diverse nature. Endoplasmic reticulum (ER) stress has emerged as a critical regulator of tumor development and drug resistance in various cancers.
