Increased expression of fetal hemoglobin (HbF) may ameliorate the clinical course of hemoglobinopathies. Hydroxyurea (HU) is the only inducer approved for the treatment of these diseases able to stimulate HbF production but patients' response is highly variable indicating the utility of the identification of pharmacogenomic biomarkers in order to predict pharmacological treatment efficacy. To date few studies to evaluate the role of genetic determinants in HU response have been conducted showing contradictory results...

INTRODUCTION: Retroperitoneal seminoma is a very rare form of cancer, with embryological origin represented by primordial germ cells from the urogenital ridges left behind during the fetal development. Extragenital germ cell tumors can also occur in the mediastinum or the pineal gland. The aim of this paper is to outline the particularities and draw embryological, histopatological and treatment conclusions regarding extragonadal germ cell tumors. PATIENT AND METHODS: A 43-year-old patient without any additional pathology was admitted for anemia of unknown etiology...

Preeclampsia is a serious pregnancy-specific condition, affecting 10 million women annually worldwide. No specific treatment is currently available. Recent studies have demonstrated abnormal production and accumulation of free fetal hemoglobin in the preeclamptic placenta, and identified subsequent leakage into the maternal circulation as an important factor in the development of preeclampsia. A recombinant version of alpha-1-microglobulin, an endogenous well-characterized heme and radical scavenger, has been developed...

Different hemoglobin isoforms are expressed during the embryonic, fetal and postnatal stages. They are formed by combination of polypeptide chains synthesized from the α- and β-globin gene clusters. Based on the fact that the presence of high hemoglobin F levels is beneficial in both sickle cell disease and severe thalassemic syndromes, a revision of the regulation of the β-globin cluster expression is proposed, especially regarding the genes encoding the y-globin chains (HBG1 and HBG2). In this review we describe the current knowledge about transcription factors and epigenetic regulators involved in the switches of the β-globin cluster...

Allogeneic hematopoietic stem cell transplantation has been established for several decades as a gene replacement therapy for patients with thalassemia major and now offers very high rates of cure to those who are able to access this therapy. Outcomes have improved tremendously over the last decade even in high-risk patients. The limited data available suggests that the long-term outcome is also excellent with >90% survival but for best results, hematopoietic stem cell transplantation should be offered early before any end organ damage occurs...

Induction of fetal hemoglobin (HbF) has therapeutic importance for patients with beta-hemoglobin disorders. Previous studies showed that let-7 microRNAs (miRNAs) are highly regulated in erythroid cells during the fetal-to-adult developmental transition, and that targeting let-7 mediated the up-regulation of HbF to greater than 30% of the total globin levels in human adult cultured erythroblasts. HMGA2 is a member of the high-mobility group A family of proteins and a validated target of the let-7 family of miRNAs...

BACKGROUND: Worldwide, 199.5 million women have diabetes mellitus (DM). Preconception care (PCC) education starting from adolescence has been recommended as an effective strategy for safeguarding maternal and child health. However, traditional preconception care advice provided by health care professionals (HCPs) within clinic settings is hindered by inadequate resources, suboptimal coverage, and busy clinics. Electronic health (eHealth), which is instrumental in solving problems around scarce health resources, could be of value in overcoming these limitations and be used to improve preconception care and pregnancy outcomes for women with DM...

We present a patient with a compound heterozygosity codon 39 (C > T) (β(0)) [or β39(C5)Gln→Stop (G39X); CAG > TAG; HBB: c.118C > T] and -87 (C > T) (β(+)) (HBB: c.-137C > T) β-globin mutations, a non transfusion-dependent thalassemia phenotype and 97.0% fetal hemoglobin. A novel heterozygous mutation was identified in a highly conserved residue in the COOH-terminus of the Krüppel-like factor 1, R360H, that likely altered DNA-binding and impaired transactivation.

Diabetes in pregnancy is associated with higher rates of miscarriage, pre-eclampsia, preterm labor, and fetal malformation. To prevent these obstetric and perinatal complications, women with diabetes have to control levels of blood sugar, both prior to and during pregnancy. Thus, individualized medical nutrition therapy for each stage of pregnancy is essential. We provided in-depth medical nutrition therapy to a 38-year-old pregnant woman with diabetes at all stages of pregnancy up to delivery. She underwent radiation therapy after surgery for breast cancer and was diagnosed with diabetes...

Stress erythropoiesis induces fetal hemoglobin (HbF) expression in β-thalassemias, however the level of expression is highly variable. The last decade has seen dramatic advances in our understanding of the molecular regulators of HbF production and the genetic factors associated with HbF levels, leading to the promise of new methods of the clinical induction of HbF. Areas covered: This article will review the heterogeneity and genetic modifiers of HbF and HbF induction therapy in β-thalassemia. Expert commentary: One promising curative β-thalassemia therapy is to induce HbF synthesis in β-thalassemic erythrocytes to therapeutic levels before clinical symptom occurs...

Juvenile myelomonocytic leukemia (JMML), previously known as juvenile chronic myeloid leukemia (JCML), is a rare, myelodysplastic-myeloproliferative disease typically presenting in early childhood. This disorder is difficult to distinguish from other myeloproliferative syndromes such as chronic myeloid leukemia (CML) because of the similarities in their clinical and bone marrow findings. However, because of its unique biological characteristics such as absolute monocytosis with dysplasia, absence of Philadelphia chromosome or BCR-ABL fusion protein, hypergammaglobulinemia, and raised fetal hemoglobin level, this disorder does not satisfy the criteria for inclusion in the CML or chronic myelomonocytic leukemia (CMML) group, as seen in adult patients...
