Myelodysplastic/myeloproliferative neoplasms (MDS/MPN) are not a single illness; instead, a multifaceted group of diseases is emerging, characterized by their frequent genetic abnormalities. While extremely uncommon, chromosomal translocations affecting meningioma 1 (MN1) and ETS variant 6 (ETV6) genes are repeatedly observed in myeloid neoplasms. A case study details a patient with a myelodysplastic/myeloproliferative neoplasm, specifically, a neutrophilic variant, who presented an extramedullary T-lymphoblastic crisis, solely defined by the t(12;22)(p13;q12) chromosomal translocation. This instance of the case displays a number of clinical and molecular similarities to myeloid/lymphoid neoplasms marked by eosinophilia. Confronting the patient's treatment was the disease's remarkable resistance to chemotherapy, making allogenic stem cell transplantation the only possible cure. The observed clinical presentation, contrasting with previously reported cases involving these genetic alterations, lends support to the concept of a hematopoietic neoplasm arising from an early, uncommitted precursor cell. Moreover, it underscores the significance of molecular characterization in classifying and stratifying the prognosis of these entities.
Depleted iron stores in the body, a characteristic of latent iron deficiency (LID), create a significant diagnostic challenge, absent any accompanying anemia. Reticulocyte hemoglobin content (Ret-Hb) demonstrates a direct relationship with the iron resources available for erythrocyte heme synthesis. Pixantrone For this reason, Ret-Hb has been recommended as an effective measure of iron status.
Analyzing Ret-Hb's significance in identifying occult iron deficiency, and its application for the early detection of iron deficiency anemia.
Researchers at Najran University Hospital conducted a study on 108 individuals, 64 of whom were identified with iron deficiency anemia (IDA), and 44 of whom demonstrated normal hemoglobin levels. Measurements of complete blood count (CBC), reticulocyte percentage, Ret-Hb, serum iron, total iron-binding capacity (TIBC), and serum ferritin were conducted on every patient.
A considerable decline in Ret-Hb was ascertained in IDA patients in contrast with those not experiencing anemia, a 212 pg cut-off signifying IDA (levels below this value classify as IDA).
The determination of Ret-Hb, combined with complete blood count (CBC) parameters and indices, constitutes a readily available predictive marker for both iron deficiency (ID) and iron deficiency anemia (IDA). Lowering the threshold for Ret-Hb could prove more beneficial in identifying individuals with IDA through screening.
Ret-Hb measurement, alongside CBC parameters and indices, offers an accessible predictive marker for iron deficiency (ID) and iron deficiency anemia (IDA). Lowering the Ret-Hb cut-off value could yield a more comprehensive screening approach for identifying iron deficiency anemia.
A rare form of diffuse large B-cell lymphoma is marked by its spindle cell morphology. The 74-year-old male's initial presentation involved a right supraclavicular (lymph) node enlargement. Spindle-shaped cells, characterized by narrow cytoplasms, exhibited a proliferation as observed in the histological analysis. To ascertain that the tumor wasn't a melanoma, carcinoma, or sarcoma, an immunohistochemical panel was used. In accordance with Hans' classifier (CD10 negative, BCL6 positive, MUM1 negative), the lymphoma showcased a germinal center B-cell-like (GCB) subtype, further characterized by EBER negativity and the absence of BCL2, BCL6, and MYC rearrangements. Using a custom panel of 168 genes relevant to aggressive B-cell lymphomas, mutational profiling confirmed the existence of mutations in ACTB, ARID1B, DUSP2, DTX1, HLA-B, PTEN, and TNFRSF14. Pixantrone This case's subtype, as determined by the LymphGen 10 classification tool, was predicted to be ST2. The immune microenvironment displayed moderate M2-like tumor-associated macrophage (TAM) infiltration, evidenced by CD163, CSF1R, CD85A (LILRB3), and PD-L1 expression, accompanied by moderate PD-1-positive T cells and a low frequency of FOXP3-positive regulatory T lymphocytes (Tregs). There was no detectable immunohistochemical expression of both PTX3 and TNFRSF14. Significantly, the lymphoma cells were positive for HLA-DP-DR, IL-10, and RGS1, which are markers that correlate with an unfavorable prognosis in patients with diffuse large B-cell lymphoma (DLBCL). The patient's condition was effectively addressed by R-CHOP therapy, leading to a complete metabolic response.
Daprodustat, an inhibitor of hypoxia-inducible factor prolyl hydroxylase, and dapagliflozin, an inhibitor of sodium-glucose cotransporter 2, while approved in Japan for renal anemia, have not yet demonstrated their efficacy and safety in patients 80 years or older with low-risk myelodysplastic syndrome (MDS)-related anemia. Two men and a woman, aged over 80, formed the basis of this case series. They exhibited low-risk myelodysplastic syndrome (MDS)-related anemia, coupled with chronic kidney disease stemming from diabetes mellitus (DM). All were transfusion-dependent, and erythropoiesis-stimulating agents had proven ineffective. Daprodustat and the added dapagliflozin resulted in all three patients' red blood cell transfusion independence, with follow-up exceeding six months. The daily oral ingestion of daprodustat was associated with satisfactory tolerability. No fatalities or progression to acute myeloid leukemia occurred during the >6-month observation period after daprodustat was initiated. These findings support the efficacy of a daily combination therapy consisting of 24 mg of daprodustat and 10 mg of dapagliflozin for managing low-risk MDS-related anemia. Subsequent studies are needed to meticulously examine the synergistic impact of daprodustat and dapagliflozin on long-term management of low-risk MDS. Correcting chronic kidney disease-related anemia by boosting endogenous erythropoietin and normalizing iron metabolism is a key aspect.
During pregnancy, myeloproliferative neoplasms (MPNs), specifically essential thrombocythemia (ET) and polycythemia vera (PV), are a comparatively uncommon occurrence. These factors are associated with an elevated risk of thromboembolic, hemorrhagic, or microcirculatory disturbances, or placental dysfunction, which negatively impact fetal growth restriction or loss, rendering them harmful. Pixantrone Low-dose aspirin and low-molecular-weight heparin (LMWH) are advocated for reducing pregnancy complications; interferon (IFN) is the single cytoreductive treatment for pregnant women with MPN, focusing on successful live birth outcomes. As ropeginterferon alfa-2b stands as the only IFN accessible in South Korea, we describe a pregnancy case involving an MPN patient treated with this medication. A 40-year-old female, diagnosed with low-risk polycythemia vera (PV) in 2017, maintained on a regimen consisting of phlebotomy, hydroxyurea (HU), and anagrelide (ANA) for four years, was confirmed pregnant at five weeks gestation on December 9th, 2021. Following the cessation of HU and ANA therapy, a notable surge in platelet count was observed, increasing from 1113 x 10^9/L to 2074 x 10^9/L (within the normal range of 150-450 x 10^9/L), accompanied by a simultaneous rise in white blood cell count from 2193 x 10^9/L to 3555 x 10^9/L, also falling within the normal range of 40-100 x 10^9/L. With the significant risk of complications posing a considerable threat, we opted for a decisive cytoreductive strategy; ropeginterferon alfa-2b, the sole interferon agent obtainable in South Korea, was our chosen treatment modality. Eight cycles of ropeginterferon alfa-2b were administered over six months to the pregnant patient, who subsequently delivered without any neonatal or maternal issues. A review of this case emphasizes the significance of evaluating treatment protocols for MPN patients during pregnancy or those contemplating pregnancy, coupled with the requirement for further exploration into the safety and efficacy of ropeginterferon alfa-2b in these individuals.
A primary cardiac lymphoma (PCL) presentation of non-Hodgkin's lymphoma is a rare occurrence. The right side of the heart, affected by 1% of cardiac tumors, is frequently difficult to diagnose, due to the location of the lesion and the ambiguous presenting symptoms and signs, often leading to a delayed diagnosis and a poor prognosis. Our case report details the diagnosis of PCL in a middle-aged male, whose pyrexia of unknown origin was identified using F18-fluorodeoxyglucose positron emission tomography (18FDG-PET). In patients experiencing pyrexia of unknown origin (PUO), particularly when the cause is suspected to be a neoplasm, PET-CT emerges as an invaluable asset. By precisely identifying the affected area, it empowers clinicians to make the best choice in interventions leading to rapid tissue analysis. This particular case emphasizes the need for physicians to consider PCL in the differential diagnosis of PUO, especially when it mimics a relatively common cardiac tumor such as atrial myxoma.
A rare manifestation of non-Hodgkin lymphoma (NHL) is the primary cutaneous B-cell lymphoma (PCBCL), presenting with distinctive clinical and biological characteristics. Subjects with NHL have been extensively studied for their risk of autoimmune or neoplastic comorbidities, yet the existing data is not applicable to PCBCLs. This study set out to define the rate of occurrence for relevant medical conditions, with a particular emphasis on autoimmune and neoplastic disorders, in individuals with PCBCL. A retrospective observational study was undertaken, encompassing 56 patients with histologically confirmed PCBCL and 54 sex- and age-matched control subjects. Our analysis uncovered statistically significant associations for general neoplastic comorbidities (411% vs. 222%, p = 0.0034) and, more specifically, hematological malignancies (196% vs. 19%, p = 0.00041) with PCBCL, relative to control groups. A statistically insignificant difference was found in the occurrence of autoimmune comorbidities (214% vs. 93%, p = 0.1128) and chronic viral hepatitis (71% vs. 0%, p = 0.1184).
