Filter by:Delayed anaemia has been reported in European travellers with malaria cured by artesunate. Although no deaths related to this delayed anaemia have been reported so far, blood transfusion has been necessary in some affected patients. Recent observations suggest that this episodes of anaemia also occurs in endemic countries. The aim of this trial is to assess the incidence of late onset anaemia after treatment with intravenous artesunate compared to intravenous quinine, to identify patients at risk and to clarify the causes of this delayed anaemia.
This study will determine whether the haemoglobin response to daily home fortification for 30 days with 3mg iron as NaFeEDTA is non-inferior to 12.5 mg iron as encapsulated ferrous fumarate.
This study aims to characterize the relationship between dose of GSK1278863 and hemoglobin (Hgb) response in hemodialysis-dependent (HDD) subjects with anemia associated with chronic kidney disease (CKD). It is anticipated that the data generated will enable selection of the starting dose(s) and optimize dose adjustment regimen(s) for Phase 3 clinical trials. This study will consist of a screening phase of 3-9 weeks, a 4-week treatment phase and a follow-up visit approximately 4 weeks after completing treatment.
This study will be conducted in approximately 228 subjects with anemia associated with CKD who are not on dialysis. Two groups of subjects will be enrolled into the study: Group 1: recombinant human erythropoietin (rhEPO) naive subjects; Group 2: rhEPO users, who are currently receiving rhEPO. Subjects who are rhEPO naive will be randomized to receive either GSK1278863 once daily (QD) or rhEPO in a 3:1 fashion; subjects who are receiving an rhEPO before enrolling (rhEPO users) will be randomized in a 1:1 fashion to GSK1278863 QD or to the control arm. For those randomized to the control arm, the decision around whether the subject requires rhEPO, the selection of the type of rhEPO (if needed) and the choice of rhEPO dose to achieve and maintain Hgb concentrations within the target range should be based on Investigator clinical judgment, with the historical rhEPO dose and the current Hgb value being considered. The study consists of a screening phase of at least 4 weeks, a 24-week treatment phase and a follow-up visit that will occur approximately 4 weeks after completing treatment. It is anticipated that the data generated will enable selection of the starting dose(s) and optimize dose adjustment regimen(s) for Phase 3 clinical trials.
This study is intended to evaluate the dose-response relationship of GSK1278863 over the first 4 weeks of treatment and evaluate the safety and efficacy of GSK1278863 over 24 weeks to maintain hemoglobin (Hgb) level in hemodialysis-dependent (HDD) subjects with anemia associated with chronic kidney disease (CKD) who are switched from a stable dose of recombinant human erythropoietin (rhEPO). The data generated will enable selection of the starting dose(s) and optimize dose adjustment regimen(s) for Phase 3 clinical trials.
Problematic and state of the art Obesity and its associated non communicable diseases (NCDs) are rising rapidly in middle income countries, such as those in the Maghreb (North Africa). This progression is related to the context of a nutrition transition (changing food and physical activity environment) and profound changes in technological advances and in society. These societies and their health systems are insufficiently prepared for this evolution, which has enormous health and socioeconomic consequences. In the context of limited resources, the priority has been given on an international level to prevention. But several problems arise: - these countries are still confronted by undernutrition in terms of micronutrient deficiencies, which coexist with obesity and NCDs, including at a family level and also individual level. Known as the 'double burden', this coexistence is relatively new and has been rarely documented until recently. Educational measures could be ineffective in a society where cultural norms do not recognise obesity and where changes in lifestyle are possibly not seen as acceptable. As well as information about citizen's knowledge of risk factors, data on their perceptions and attitudes are indispensable. Policies that involve changing the 'obesogenic' environment that individuals occupy is a priority. Objectives of the project Overall aim: to contribute to the development of preventive strategies for obesity and chronic NCDs in the context of a nutrition transition. Specific objectives: characterise the nature and size of the double burden (obesity/undernutrition) in regions, families and individuals; estimate the prevalence of biological and behavioural risk factors; characterise the psycho-sociocultural determinants of behaviour.
Anaemia is a common problem in patients undergoing surgery. About half of patients undergoing a major operation have anaemia, often a consequence of the disease requiring surgery. Anaemia causes patients to feel tired and unwell. Anaemia at the time of surgery increases the requirement for blood transfusion (50% if anaemic compared to only 15% without anaemia). Both anaemia and blood transfusions are associated with increased complications from surgery, delayed recovery and prolonged hospital stay. The investigators propose that giving intravenous iron before operation can be used to correct anaemia in these patients. Consequently if patients are not anaemic they are less likely to need blood transfusion. Also patients feel better and their health is improved before their operation they are more likely to tolerate the surgery, recover faster, be less likely to have complications from surgery and return home sooner. This will have benefits to the individual patient and also to the NHS by reducing costs. Oral Iron tablets are not effective as they take 3-6 months to increase blood levels, the tablets are often not tolerated as cause constipation or stomach pain, overall only 30-50% of people continue taking oral iron. A full treatment dose of intravenous iron can be given in 15 minutes with minimal side effects. The effect is to rapidly increase blood counts in 2-4 weeks. The investigators propose that this treatment can be incorporated to patient preparation pathways for surgery as an outpatient without the need for additional visits to hospital. Small studies have suggested a benefit of iron therapy in orthopaedic and gynaecological surgery. This study will look at 500 patients undergoing major surgery at 20 hospitals in the UK. The investigators anticipate half of patients treated will have their anaemia corrected before operation. Patients with anaemia will be identified as part of the routine blood tests taken preoperatively and invited to take part in the study. Following informed consent, they will be randomly allocated to receive either intravenous iron or a placebo infusion of saline. Intravenous iron is a dark liquid given continuously into a vein over 15 minutes. To ensure neither doctor nor patient knows which treatment is being given both infusions will be prepared and administered by an unblinded authorised person via a black bag through black tubing. There will be no other changes to the patient's normal treatment. The main aim of this study is to assess if intravenous iron will reduce the need for blood transfusion in the time period around the operation. Further outcome measures will include; patient-reported quality of life, complications, length of hospital stay, and cost. Outcomes will be assessed both during hospital stay and after the patient has been discharged. The trial will be run through a Clinical Trials Unit with considerable experience in conducting large trials. The team has a large range of experience in anaemia management and assessment of complications, quality of life and the cost of health care.

This protocol is designed to explore whether short-term therapy with GSK1278863 affects PASP under normoxic and hypoxic conditions in healthy volunteers. Healthy subjects will be evaluated using echocardiography to estimate PASP based on the velocity of the tricuspid regurgitant jet. Resting PASP will be assessed under normoxic (room air) conditions, as well as after 30 minutes' exposure to 15% O2 before, during, and after short-term treatment with GSK1278863.
In areas of Africa where malaria is only a problem during a short rainy season, monthly courses of antimalarial drugs can provide very effective prevention of malaria in children. This approach, called intermittent preventive treatment in children (IPTc) but now known as Seasonal Malaria Chemoprevention (SMC), may also be useful in large areas of Africa where malaria is transmitted for longer each year. It is uncertain if IPTc would be effective, acceptable to communities or sustainable when delivered over a longer period, but this is an important public health question of key interest to policy makers, because in areas with a longer transmission season, the burden of malaria is typically higher than in highly seasonal areas. Another form of prevention that would be operationally easier for African countries to put into practice would be to treat malaria patients with long-lasting antimalarials, which protect children against further malaria episodes for several weeks. Because malaria disproportionately affects certain high risk children more than others, causing repeated attacks of fever and leading to severe anaemia, long-acting drugs may be a simple and effective way to target limited resources at the individuals who most need protection. This may be particularly beneficial where malaria is a seasonal problem, because repeated malaria attacks will not only be borne by a few unfortunate children, but will also occur close together in time. The investigators propose a clinical trial to evaluate these two forms of chemoprevention in Kumasi, Ghana, an area with an extended malaria transmission season. Children under 5 years of age currently have access to diagnosis and treatment of malaria via by community based health workers. Children enrolled in the study will receive either the standard community-based diagnosis and treatment, treatment with a longer-acting artemisinin combination therapy (ACT), or standard care plus five monthly courses of seasonal malaria chemoprevention (SMC) during the peak in transmission.
Impact exerted by intestinal parasitic infections is much higher in developing countries. School-aged children are at higher risk from the burden of disease, because they specially have many parasitic infections. The poor health results in deficits in physical and cognitive development and educational achievements. Nowadays, there is huge commitment among the global community to control intestinal parasitic infections and to improve nutritional status of young children in developing countries. Large-scale anthelminthic drug administration through vertical control programmes is still required for the foreseeable future and is, therefore, recommended by the World Health Organization (WHO). However, due to the inevitability of re-infection in endemic areas, children need to be treated regularly, and once morbidity control is consolidated, the strategy must shift to transmission control emphasising access to clean water and adequate sanitation. To lower dependency on 'drug only' approach and to enhance sustainability, from the onset of control activities, complementary measures should be implemented, that depend on available resources. Therefore, the investigators are proposing to undertake a randomised controlled trial to assess the impact of simple and easy-to-do hand hygiene intervention packages (hand washing with soap and hand finger nail clipping) on intestinal parasitic infection prevalence, intensity and re-infection rates and on haemoglobin concentration and anaemia prevalence rates among 6-15 years old schoolchildren. Our results will provide solid evidence on if and how hand hygiene practice affects infection prevalence and re-infection rates, as well as, anaemia prevalence among the highly vulnerable age group.
