Vitamin D, a secosteroid, is essential for the development and maintenance of healthy bone in both the adult and pediatric populations. Low level of 25-hydroxy vitamin D (25-(OH)-D) is highly prevalent in children worldwide and has been linked to various adverse health outcomes including rickets, osteomalacia, osteomalacic myopathy, sarcopenia, and weakness, growth retardation, hypocalcemia, seizure and tetany, autism, cardiovascular diseases, diabetes mellitus, cancers (prostate, colon, breast), infectious diseases (viral, tuberculosis), and autoimmune diseases, such as multiple sclerosis and Hashimoto's thyroiditis...

INTRODUCTION: Inherited anemias diagnostic workup requires a step-wise algorithm. Causal genes implicated in congenital hemolytic anemia are numerous, making a gene-by-gene approach by Sanger sequencing time consuming, expensive and labour intensive. Targeted resequencing can be of great use in explaining these cases. METHODOLOGY: Six months female presented with neonatal jaundice and negative family history. Clinical and laboratory evidences were suggestive of hemolytic anemia...

Renal medullary carcinoma (RMC) is a rare, yet aggressive malignancy of the kidney that is found predominantly in young patients with African descent and sickle cell hemoglobinopathies and most specifically sickle cell trait. Due to its aggressive nature, most cases have metastasis or local invasion at the time of diagnosis. Prognosis is extremely poor with survival less than 1 year after diagnosis. Here we present a case of metastatic RMC in a 29-year-old African female. Despite chemotherapy with cisplatin, gemcitabine, and paclitaxel, and initial shrinkage of the tumor, the patient died 5 months after diagnosis...

BACKGROUND: Alpha globin chain variants are clinically significant since they directly influence the structure and function of the hemoglobin (Hb) molecules they constitute, either in combination with normal beta globin chains or with variant beta chains, thereby altering the morbidity and mortality associated with the resultant hemoglobinopathies. We describe here two unrelated families from Madhya Pradesh who had a nondeletional alpha-chain variant, HbO Indonesia (CD116 G → A). Members of one of the two families also had coinheritance of sickle hemoglobin (HbS)...

Red blood cells (RBC) are the most abundant host cells in the human body. Mature erythrocytes are devoid of nuclei and organelles and have always been regarded as circulating 'bags of hemoglobin'. The advent of proteomics has challenged this assumption, revealing unanticipated complexity and novel roles for RBCs not just in gas transport, but also in systemic metabolic homeostasis in health and disease. Areas covered: In this review we will summarize the main advancements in the field of discovery mode and redox/quantitative proteomics with respect to RBC biology...

BACKGROUND: Sickle cell anemia is a congenital hemoglobinopathy characterized by deformed red blood cells. Oxidative stress plays an important role in the pathophysiology of sickle cell anaemia as it destroys free radicals, and thereby depleting the protective mechanisms such as antioxidants in serum. These antioxidants are essential to protect against harmful oxidation-reduction reactions preventing oxidative damage to the cells. AIM: To evaluate and compare the Total Antioxidant Capacity (TAC) of serum and saliva in sickle cell anemia patients...

Salmonella osteomyelitis is well-described in children with hemoglobinopathies, particularly infection with Salmonella typhi. To characterize non-typhoidal osteomyelitis in otherwise healthy children without hemoglobinopathies, we performed a retrospective review of children discharged from our institution with this condition, supplemented with a systematic literature review. Among the 46 subjects identified, common risk factors for Salmonella infection were frequently absent and complications were common.

Allogeneic hematopoietic cell transplantation (HCT) effectively treats several non-malignant disorders such as selected lysosomal disorders, cerebral adrenoleukodystrophy and hemoglobinopathies. However, rates of graft failure (GF) in non-malignant populations exceed those of patients with malignant indications for HCT. Salvage conditioning regimens and outcomes for second HCT for GF vary immensely in the literature. We report 17 consecutive pediatric patients with non-malignant disorders who underwent a second allogenic HCT for GF using a non-myeloablative, low-dose busulfan-based regimen...

Congenital causes of erythrocytosis are now more easily identified due to the improvement of the molecular characterization of many of them. Among these causes, hemoglobins with high oxygen affinity take a large place. The aim of this work was to reevaluate the diagnostic approach of these disorders. To assess the current practices, we sent a questionnaire to the expert laboratories in the diagnosis of hemoglobinopathies in France and Belgium. In parallel, we gathered the methods used for the diagnosis of the hemoglobins with high oxygen affinity indexed in the international database HbVar...

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...

Red cell alloimmunization is a serious problem in chronically transfused patients. A number of high-throughput DNA assays have been developed to extend or replace traditional serologic antigen typing. DNA-based typing methods may be easily automated and multiplexed, and provide reliable information on a patient. Molecular genotyping promises to become cheaper, being not dependent on serologic immunoglobulin reagents. Patients with hemoglobinopathies could benefit from receiving extended genomic typing. This could limit post transfusional complications depending on subtle antigenic differences between donors and patients...

BACKGROUND: Thalassemia and hemoglobinopathies are inherited red blood cell disorders found worldwide. Hemoglobin (Hb) E disorder is one of the hemoglobinopathies known to have the high prevalence in South East Asia. Most of transfusion-dependent thalassemias were genotypically compound heterozygous Hb E/ β-thalassemia. In Malaysia, the national screening program for thalassemia was implemented for early pregnancy or secondary school girls; however many participants do not turn-up and missed the screening test...

Sickle-cell diseases are the most common inherited hemoglobinopathies worldwide. Improvement in survival has been seen in the last decades with the introduction of careful screening and prevention of complications and the introduction of hydroxyurea. Stem-cell transplantation is currently the only curative option for these patients and has been indicated for patients with neurological events, repeated vaso-occlusive crisis, any organ damage or presence of red blood cell antibodies. Related bone-marrow or cord-blood transplant has shown an overall survival of more than 90% with a disease-free survival of 90% in 1,000 patients transplanted in the last decades...

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...

Sickle cell syndrome HbS/β thalassemia is an inheritable mendelian type disease where two affected alleles are simultaneously present, one from HbS (βS) and the other from β thalassemia. That situation is mainly linked to individuals who share African and Mediterranean ancestors. The mutation responsible for HbS is a point mutation, whereas for β thalassemia, there are more than 200 mutations that cause different degrees of deficiency synthesis of β globin chain, which justifies the clinical and genetic heterogeneity of this syndrome...
