Active clinical trials for "Anemia"

The drug that is under investigation during this study is BAY85-3934 which is intended to be used as a treatment for patients suffering from renal anemia due to chronic kidney disease (stage 3 and 4). The purpose of this study is to provide safety and tolerability information on the drug. Other objectives of the study are to investigate the effect of the drug on the body (pharmacodynamics) as well as the absorption, breakdown, metabolism, distribution and excretion (pharmacokinetics) by measuring the concentration in blood and urine. The study will be conducted in one study center in the United Kingdom and several centers in Germany. 84 (of which 36 are optional) patients who meet the inclusion criteria will participate in the study. BAY 85-3934 will be given following a combined single / multiple dose escalation design in seven (of which three are optional) dose steps.

Every individual receiving a general anesthetic is at potential risk for developing a ''cannot intubate-cannot ventilate'' situation following anesthetic induction. Building up of oxygen reserves assumes great significance as this provides a longer duration of non-hypoxic apnea should one be faced with an unanticipated difficult airway. The main physiological functions of red blood cell hemoglobin are to deliver oxygen to the peripheral tissues. During anemia, a reduction in blood oxygen content occurs as a result of reduced Hb while arterial oxygenation and oxyhemoglobin saturation remain high. Previous studies about the duration of non-hypoxic apnoea focus on methods to improve the safety period of tracheal intubation. To our knowledge, there is no literature about the duration of non-hypoxic apnoea of anemia patients. The aim of this study was to assess the effect of chronic anemia on the duration of non-hypoxic apnoea during induction of anaesthesia.

Iron deficiency anemia is the most common nutritional problem in the world. The objectives of this study are: to evaluate the prevalence of anemia in children from 6 to 24 months of age and the therapeutic and prophylactic response to ferrous sulfate plus folic acid on hemoglobin levels. to compare the effect of folic acid supplementation with ferrous sulfate on the linear and weight growth of anemic and non-anemic Study hypothesis: The ferrous sulfate plus folic acid can improve the response on hemoglobin levels. The folic acid supplementation with ferrous sulfate have effect on the linear and weight growth of anemic and non-anemic.

Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Epoetin alfa may stimulate red blood cell production to treat anemia in patients who have received chemotherapy and/or radiation therapy for cervical cancer. Randomized phase III trial to study the effectiveness of epoetin alfa in treating anemia in patients who have cervical cancer.

Anemia in patients with myocardial infarction (MI) is a relatively frequent issue, resulting in poorer outcome. There is equipoise regarding which transfusion strategy is best, and there is an international consensus on the urgent need for a randomized trial. The investigators hypothesize that a "restrictive" transfusion strategy is at least non-inferior to a "liberal" transfusion strategy on 30-day outcomes of MI patients with anemia. Given the costs and risks of transfusion, a cost-effectiveness and cost-utility analysis becomes key to determining the role of each strategy.

A clinical trial was conducted in 65 PLWH randomly allocated to receive standard hospital diet alone (Control group: n=33), or the diet combined with 100 g/day of RUTF (RUTF group: n=32). Individual dietary intakes were measured and compared to the Recommended Dietary Allowances (RDA) for PLWH. Body composition was measured by bio-impedance analysis (BIA), hemoglobin by HemoCue and plasma zinc concentration by atomic absorption spectrometry and adjusted to infection (CRP and α1-AGP). All measures were conducted at baseline, 3 weeks and after 9 weeks home-based follow up.

The treatment of HCV (hepatitis C virus) infection has made significant progress over the past decade with the therapy combining pegylated interferon (Peg-IFN) to ribavirin (RBV). The cure of HCV infection which consists to obtain a sustained virological response (SVR) (undetectable HCV RNA 24 weeks after end of treatment) is reached in more than 50% of patients infected with HCV. However, this rate is much lower, around 30 to 40% in HIV-HCV co-infected patients and sometimes can be less than 20% for patients infected with HCV genotype 1. Haemolytic anemia is a dose-limiting adverse effect which occurs frequently under RBV therapy. RBV-induced anemia represents the main cause of treatment discontinuation or dose reduction of RBV, thus limiting the chances of achieving a SVR. RBV has a large inter-individual pharmacokinetic variability and a relationship between the occurrence of anemia and RBV concentration was clearly demonstrated. However, other factors, including genetic factors, could be predictive of hematotoxicity and/or a better efficiency. In particular, IL-28B polymorphism analysis, in patients infected with HCV genotype 1, before starting antiviral therapy could predict the response to treatment (positive predictive value). The genetic polymorphism of inosine triphosphate pyrophosphatase (ITPA) is also strongly associated to a protective effect towards the RBV-induced-anemia. But most of these data are issued from studies performed in a Japanese HCV mono-infected population treated with Peg-IFN-RBV therapy for which there is no other causal variant that the rs1127354. Only few studies are reported in the literature in caucasian HIV-HCV co-infected patients. Moreover, data on RBV plasma exposure are very scarce in all these studies showing an impact of the ITPA polymorphism on the occurrence of anemia. In addition, others polymorphisms of SCL29A1/A2 and SCL28A2/A3 coding for RBV transporters, ENT (equilibrative nucleoside transporter) et CNT (concentrative nucleoside transporter) would be associated to either rapid virological response or anemia in HCV infected patients treated by Peg-IFN plus RBV. No study considering both polymorphisms of ITPA, IL-28B, SCL29A1/A2 and SCL28A2/A3 genes and RBV plasma exposure data has so far been conducted in HIV-HCV co-infected patients. Thus, it would be interesting in a first time to assess the impact of the ITPA polymorphism on both the RBV plasma exposure and the protective effect towards RBV-induced anemia in HIV-HCV co-infected patients. This study could be helpful to the literature for possible further RBV dose adjustments according to ITPA activity. Then, it would be relevant to further complete these data by assessing other genetic polymorphisms as IL-28B, SCL29A1/A2 and SCL28A2/A3 and thus evaluate the overall pharmacogenetic relationships towards RBV-induced anaemia and/or virological response to a Peg-IFN/RBV therapy.

The proposed project is aimed at testing two interventions, namely a highly bioavailable iron compound and a combination of SP plus amodiaquine for intermittent preventive treatment (IPT) of malaria, to reduce anaemia in very young children.

This is an open-label study to understand the safety and tolerability of AXA4010, a novel composition of amino acids in adult and adolescent subjects with sickle cell disease over 12 weeks. The study also assesses the effects of this amino acid composition on the structure and function of the vascular system. Physiological effects on structure and function will be assessed by Magnetic Resonance Imaging (MRI) to assess blood flow in the brain and kidneys and the 6-Minute walk with pulse oximetry. Changes in blood biomarkers of inflammation will also be assessed.

The specific aims of the current study were: 1) To determine the prevalence of IDNA in a sample of female rowers at the beginning of a training season; 2) To determine how IDNA affects endurance training and performance at the beginning of a training season; 3) To determine how iron supplementation affects iron status, training and performance in IDNA female collegiate rowers. The researchers hypothesized that IDNA affects endurance performance in female collegiate rowers both in and outside of the laboratory, and that iron supplementation of IDNA rowers will improve iron status, and consequently, training quality via increased energetic efficiency.
