Black cohosh extract (BCE) is a widely used dietary supplement marketed to women to alleviate symptoms of gynecological ailments, yet its toxicity has not been well characterized. The National Toxicology Program (NTP) previously reported significant increases in micronucleated erythrocytes in peripheral blood of female Wistar Han rats and B6C3F1/N mice administered 15-1,000 mg BCE/kg/day by gavage for 90 days. These animals also developed a dose-dependent nonregenerative macrocytic anemia characterized by clinical changes consistent with megaloblastic anemia...

OBJECTIVE: The past studies found that the treatment of chronic myeloid leukemia (CML) with imatinib can induce the macrocytic anemia, moreover the incidence of anemia increases along with enhancement of imatinib concentration. This study was aimed to evaluate the potential relation of erythrocyte mean corpuscular volume (MCV) increase after the treatment with tyrosine kinase inhibitors (TKI) with the therapeutic response in patients with CML-chronic phase (CML-CP). METHODS: The clinical and hematologic data including MCV, molecular and cytogenetic response of 119 patients with CML-CP were collected after treatment with TKIs, and the relation of MCV changes after treatment with the clinical characteristics and therapeutic efficacy for patients with CML-CP was analyzed...

The congenital dyserythropoietic anemias are a heterogeneous group of disorders characterized by anemia and ineffective erythropoiesis. Congenital dyserythropoietic anemia type I (CDA1) can present in utero with hydrops fetalis, but more often it presents in childhood or adulthood with moderate macrocytic anemia, jaundice, and progressive iron-overload. CDA1 is inherited in an autosomal recessive manner, with biallelic pathogenic variants in CDAN1 or C15orf41. This case report documents a severe fetal presentation of CDA1 where we identified two novel compound heterozygous mutations in CDAN1 and describes the associated pathologic findings and levels of iron-regulatory proteins hepcidin, erythroferrone, and GDF15...

Pearson syndrome (PS) is a rare mitochondrial disorder that usually presents with transfusion-dependent macrocytic anemia, exocrine pancreatic dysfunction, and lactic acidosis. Typical bone marrow (BM) features are vacuolization in hematopoietic progenitors, hypocellularity, and ringed sideroblasts. At the neonatal age, PS may have a variable clinical onset. Moreover, there is little information about BM features at this age and the timing of their presentation. We report a neonatal case of PS that presented with refractory anemia and atypical BM features...

BACKGROUND: Anemia has been shown to worsen cardiovascular diseases. However, it is unclear whether there is a gender difference in the impact of anemia on subclinical myocardial damage and cardiovascular mortality in the general population. METHODS: A prospective cohort study was conducted in a community based on annual health checks. Serum heart-type fatty acid binding protein (H-FABP) levels, which is a marker for myocardial damage, and blood counts were measured at baseline in subjects without previous cardiovascular diseases (n=3111)...

INTRODUCTION: Evaluation of red blood cell (RBC) morphology is an important first step in the differential diagnosis of hereditary hemolytic anemia. It is, however, labor intensive, expensive, and prone to subjectivity. To improve and standardize the analysis of RBC morphology as a screening tool in the diagnosis of hereditary hemolytic anemia, we studied its automated analysis by digital microscopy (DM). METHODS: Blood from 90 patients with hereditary hemolytic anemia and 32 normal control subjects was analyzed by the CellaVision DM96 Digital Microscope...

Clinical copper deficiency is now more frequently recognized. Hematologically, it can present as anemia (microcytic, normocytic, or macrocytic) and neutropenia. Thrombocytopenia is relatively rare. Neurologically, it can manifest as myelopathy and peripheral neuropathy simulating subacute combined degeneration. Bone marrow findings can mimic myelodysplasia resulting in occasional inappropriate referral for bone marrow transplantation. Other conditions with similar presentations include infections, drug toxicity, autoimmunity, B12 deficiency, folate deficiency, myelodysplastic syndrome, aplastic anemia, and lymphoma with bone marrow involvement...

Although mutations in RNA splicing genes occur frequently in patients with clonal cytopenias of unknown significance (CCUS) and myelodysplastic syndromes (MDS), very often additional common myeloid gene driver mutations are present at diagnosis. Thus, the clinical significance of isolated mutations in the most commonly mutated RNA splicing genes remains unknown. Here we report five unusual patients with an isolated mutation causing a loss of function of ZRSR2, a protein required for recognition of a functional 3' splice site...
