Filter by:INTRODUCTION Circulatory changes associated with fetal anemia have an important role in maintaining sufficient tissue oxygenation. With fetal anemia, hyperdynamic circulation and increased cardiac output occurred. In current practice, using Doppler in assessment of the peak systolic velocity (PSV) of the middle cerebral artery (MCA) is the main parameter in screening of fetal anemia. Myocardial performance index (MPI) is a noninvasive technique that evaluates systolic and diastolic cardiac function by pulsed Doppler. Patients and Methods: This prospective study will be carried out on Women with singleton pregnancies with Rh isoimmunization who are scheduled to have intrauterine blood transfusion. Selected patients will be monitored weekly from 18 weeks gestational age till 28 weeks of gestational age. Venous and arterial Doppler indices: 1. Middle cerebral artery (MCA) peak systolic velocity (PSV) 2. Umbilical Artery Pulsitility Index (PI) and Resistant Index (RI) 3. Ductus venosus (DV) Doppler Cardiac functions: 1. Global cardiac function evaluated by Modified Myocardial Performance Index (Mod-MPI) 2. Diastolic cardiac function evaluated by relationship between the maximal velocities of the E and A waveforms of ventricular filling (E/A ratio)
This is an open, Phase I / II clinical trial to evaluate the safety and efficacy of a hematopoietic gene therapy procedure with an orphan drug consisting of a lentiviral vector carrying the FANCA gene for patients with Fanconi Anemia of Subtype A . CD34 + cells derived from bone marrow and / or mobilized peripheral blood (fresh and / or cryopreserved) from patients with Fanconi subtype A (FA-A), will be transduced ex vivo with a lentiviral vector carrying the gene FANCA (orphan drug) . After transduction the cells will be inoculated in patients in order to restore their hematopoiesis with genetically corrected stem cells.
Ferrous sulfate is rapidly absorbed and the bolus of iron enters blood rather quickly possibly leading to higher concentrations of non-transferrin bound iron which induces oxidative stress. The objective of this study was to determine how quickly iron enters into blood stream from the iron-enriched Asperigillus oryzae (AspironTM, ASP) in contrast to ferrous sulfate. Seventeen healthy, female subjects (18-35 y) were randomized, double blind, cross-over experimental design with three treatments: 10 mg iron as FeSO4 and ASP as well as 20 mg iron as ASP.
Crohn's disease (CD) and ulcerative colitis (UC) are chronic gastrointestinal diseases characterized by relapsing and remitting inflammation of the intestines Anemia may often complicate the course of inflammatory bowel disease (IBD). The cause of anemia in IBD is multifactorial In the chronically ill patients, it has been described that the mechanism underlying anemia involves hepcidin.A potential mechanism underlying anemia during an chronic disease is suggested by recent data demonstrating a hepcidin lowering effect of vitamin D
This is a Phase 2, randomized, open-label study to evaluate vadadustat versus epoetin alfa for the treatment of anemia in subjects with Dialysis-dependent Chronic Kidney Disease (DD-CKD) who are hyporesponsive to erythropoiesis stimulating agents (ESAs.)
Transfusion of red blood cells is an everyday practice in critical care with the primary aim of restoring adequate tissue oxygenation. However, blood transfusion may also be harmful and costly, therefore a so called restrictive transfusion regime has been suggested by recent guidelines. These transfusion guidelines consider certain levels of hemoglobin as transfusion trigger, which on its own gives little information if any about the balance between oxygen delivery (DO2) and consumption (VO2). Hence, there is a clear need for additional physiologic transfusion trigger values. One of the potentially useful and easily obtainable physiological parameters is the central venous oxygen saturation (ScvO2), which has been shown to be a potential transfusion trigger value in hemodynamically stable but anemic patients. However, the role of ScvO2 as a transfusion trigger value was examined only in a retrospective observational study and in animal experiment. The normal value of ScvO2 in a resting adult at rest is around 70-75%, which is the product of the VO2 and DO2 relationship. Low ScvO2 usually indicates inadequate DO2. It was found in an observational study that if ScvO2>70% before transfusion due to transfusion only the value of hemoglobin increased but the value of ScvO2 did not change. This finding indicates that the DO2 may have been adequate in spite of the low hemoglobin value and the transfusion may have been unnecessary. In one of their recent animal experiments, the investigators reported that in an isovolemic-anemia model the value of ScvO2<70% was only reached when the value of hemoglobin was far less, 59 g/L, than the recommended lowest value of 70g/L as transfusion trigger by guidelines. Despite the pathophysiological rationale and the encouraging results of retrospective studies and animal experiments, prospective randomized trials in order to test the effects of an ScvO2-assisted transfusion protocol are yet to be performed. The aim of this study is to investigate the effects of an ScvO2-assisted transfusion protocol as compared to the guideline-based, hemoglobin levels guided transfusion practice.
Single-arm study to investigate the repeatability and reproducibility of SpHb measurements from the Rad-67 and DCI Mini sensor.
The Novel use Of Hydroxyurea in an African Region with Malaria (NOHARM) study is the first placebo-controlled randomized clinical trial of hydroxyurea treatment in a malaria endemic region. NOHARM has now achieved full enrollment; all children have completed the blinded portion of the protocol and are in the open-label study treatment portion. This extension study of maximum tolerated dose (MTD), addresses the next critical set of questions about the optimal dosing and monitoring of hydroxyurea treatment for children with SCA in low-resource settings. By providing guidance about optimal hydroxyurea treatment, the NOHARM MTD Study will directly inform policies that can transform the health of African children living with SCA.
Childhood anemia is a global public health problem that is associated with life-threatening consequences such as growth retardation, impaired motor and cognitive development, and increased morbidity and mortality. Anemia can be caused by a variety of factors such as nutritional deficiencies (i.e., iron, folic acid, vitamin B12, and vitamin A), infections (i.e., helminth), and blood disorders (i.e., hemoglobinopathies). The World Health Organization (WHO) estimates that approximately 50% of anemia cases can be attributed to iron deficiency. This is an estimated global average that varies widely depending upon the location in question. The World Bank estimates for 2011 claim that approximately 55.60% of all Bangladeshi children under five years of age are suffering from anemia. The relationship between socioeconomic status (SES) inequality and anemia among the children has never been conclusively and it is unclear if the children of the age group of 6-59 months have uniformly high levels of anemia during all the stages of development, e.g., during the infant, toddler, and preschool stages. In addition, there is a dearth of evidence from Bangladesh, where the meaning of sociodemographic characteristics may be different from that in other countries. Therefore, this study attempts to fill the above-mentioned lacuna by investigating and evaluating the association of SES inequality, among other explanatory variables, on the development of childhood anemia during different stages of child development and to answer the questions: (a) Is SES a factor impeding childhood anemia along with other explanatory variables? (b) In which stage of child development, the chance of disparaging with childhood anemia is highest? (c) Is there evidence of between child development stages differences in the strength and form of association disparities between having childhood anemia and SES? (c) What are the predictive margins for SES-associated anemia in the case of infants, toddlers, and preschool children? The results of this analysis will be reported for elucidating the potential effects of SES and the stages of child development that are usually neglected in the conventional scientific literature. Moreover, as anemia is one of the current key health issues in Bangladesh, it is also expected that the findings of this study would contribute significantly toward shaping the health policy strategy of the country.
Despite significant advances in the field of medicine and healthcare, anemia continues to be a major public health problem worldwide. The situation is particularly acute in developing countries where females belonging to the reproductive age category are especially vulnerable to the malady. Given the multifactorial nature of this disease, correcting anemia often requires the adoption of an integrated approach. Therefore, it is imperative that the role played by the "causes of the causes" (i.e., the sociodemographic determinants of risk), along with other contributing factors, must be identified, and addressed in order to effectively combat this disease. In general, it is terrible to sort out the psychosocial factors from the demographics, environmental and poverty-related causes. Therefore, the objective of this study is to use a nationwide representative survey to explore the magnitude of household economic inequalities contribute towards the prevalence of anemia among ever-married women in Bangladesh. The study also aims to examine the inference of other explanatory variables that frequently had supposed decomposing on the burden of anemia. Thus, this study answers the questions: (a) what are the strengths and likelihoods of having mild, moderate or severe anemia among the ever married women of different SES?; (b) do other factors viz., demographics, diabetes, maternity, and BMI affects the strength and form of the association between SES and anemia?; (c) which explanatory variable is more prone to pose anemia among the women? As the burden of anemia is one of the key policy issues facing Bangladesh, the findings generated by this study are expected to contribute towards further policy making by virtue of identifying associated risk factors. This is expected to be instrumental for program purposes designed to prevent anemia among Bangladeshi women.
