Active clinical trials for "Anemia"

Critical patients which requiring admission to intensive care (IT) are a special group of patients. In these patients the prevalence of anemia reported in studies is 75%. This prevalence is similar to that in the retrospective observational study conducted in our intensive care unit(ICU). Of the 783 patients included in the study, 551 (73.37%) had anemia on admission. Frequently anemia is present on discharge from ICU or hospital and may persist for an average of 11 weeks. Some studies have reported the presence of anemia as far as 6 months after discharge. It is widely accepted that anemia has a negative impact on rehabilitation and quality of life, but the treatment can not be exclusively based on blood products due to the risks associated with transfusion. Alternative treatments such as injectable iron or erythropoietin should be considered. The Transfusion Management Initiative Group recently issued recommendations on perioperative anemia. Similar recommendations for ICU have not yet been developed in Romania. The current study has two main purposes. The first to adopt the perioperative anemia diagnostic algorithm and adapt it to anemic patients on ICU; the second to identify patients with mixed anemia (inflammatory and iron deficient anemia) who can benefit from treatment with iron.

The purpose of this trial is to study the effect that anemia and Red Blood Cell (RBC) transfusions have on oxygen levels in the digestive tracts of Extremely Low Birth Weight (ELBW) infants and to look for possible markers in a baby's blood, urine and/or stool that may lead to a better understanding of what makes an ELBW infant at risk for digestive tract problems such as necrotizing enterocolitis.

Anemia concerns a lot of patients with cancer and affects their quality of life (QOL). Numerous studies in oncology have demonstrated the benefit of erythropoiesis-stimulating agents (ESA) in the treatment of anemia. ESAs allow the improvement of QOL,of the hemoglobin level (Hb) and is a validated alternative to transfusion. However, in hematology, if there are some specific recommendations for the use of ESAs in lymphoid pathology, there are none for myeloid disorders and in the context of autografts and allogeneic hematopoietic stem-cell transplantation (HSCT). Thus, the investigators are in particular interested in both indications: treatment of anemia in acute myeloid leukemia (AML) patients treated with chemotherapy, and the in patients receiving a myeloablative or a non-myeloablative conditioning before allogeneic HSCT, whatever type of donor and cell source.

Iron deficiency is considered one of the main nutritional deficiency disorders despite the apparent availability of a high-quality diet even in developed countries, and Iron deficiency anemia (IDA) is the most common form of anemia in the world. IDA during pregnancy has been associated with adverse health consequences for both the mother and her developing fetus. Helicobacter pylori (Hp) may be the most common bacterial infection worldwide, infecting almost half of people in developed countries and 80% of people in developing countries. The available data on the prevalence of Hp infection in Taiwan population was 54.4%. We all know that infection with Hp is strongly associated with peptic ulcer and gastric cancer, but recent evidence suggests that Hp is associated with iron deficiency and anemia, although the mechanisms remain unclear. Till now, only few previous studies specifically have addressed a potential role of Hp infection on anemia or iron deficiency during pregnancy. Our previous Research showed, between the Hp infection (+) and Hp infection (-) gravidas, the associations between the Hp infection and iron deficiency were stronger, although not statistically significant. This might be due to that we needed more cases and evidences to prove the relationship between maternal Hp infection and serum iron, ferritin and hemoglobin levels, or we should further consider the interactions of the particular customs or diet preference of the Taiwanese gravidas. This longitudinal study will recruit 140 women from the antenatal care clinics of E-Da Hospital to examine the association between Hp infection and maternal IDA. The standardized interviews of mothers (anthropometric data, socioeconomic status, medical history, obstetric history, alcohol consumption during pregnancy, and history and duration of iron supplementation during pregnancy) will be conducted, Hp infection status will be determined by the urea breath test and IgG enzyme immunoassay, and the measurement of hemoglobin, iron, and ferritin levels will be obtained 5 times at various antepartum and postpartum points of time during pregnancy (routine prenatal visits of 1st, 2nd, and 3rd trimester, puerperium and 2 weeks after delivery). We hope that we could investigate the possible role of Hp infection in iron deficiency and iron-deficiency anemia during pregnancy in Taiwan, and that early detection and treatment of anemia may reduce the risk of blood transfusion and perinatal and maternal mortality.

The purpose of the study is to determine the trigger for blood transfusions in Israeli ICU patients and the possible effects of anemia on the post ICU discharge course.

This is a national, multicenter, ambispective, observational post-authorization study (EPA-SP for its acronym in Spanish) to describe the incidence, clinical management and outcome of aplastic anemia in hospitals throughout Spain.

Investigator have previously shown that hepcidin is up-regulated even by low levels of inflammation and, according to our prior stable isotope studies, is predicted to block iron absorption. In this follow-up observational study, investigator aim to elucidate the potential drivers of this low-grade inflammation and to recalibrate the relationship between hepcidin and iron absorption using a more direct measure of absorption than the stable isotope method which measures the net of absorption and utilization. Investigator will study 120 ostensibly well children (6-24m) living in the rural region of West Kiang. Investigator will: Use detailed clinical screening for possible origins of the low grade inflammation. Assess iron absorption and its relationship to iron and anaemia status, inflammation, EPO, erythroferrone and hepcidin.

The Investigator have previously shown that hepcidin is up-regulated even by low levels of inflammation and, according to our prior stable isotope studies, is predicted to block iron absorption. In this follow-up observational study, the investigator aim to characterise the relationship between infections, acute inflammation, hepcidin and iron iron deficiency anaemia in rural African children. The Investigator will study 200 sick children (6-36 months of age) living in the rural region of West Kiang. The Investigator will: Recruit 50 sick febrile children in each of 4 categories; Upper Respiratory tract infections, Lower respiratory tract infections (pneumonia), Urinary tract infections, gastroenteritis. Assess iron absorption and its relationship to iron and anaemia status, inflammation, EPO, erythroferrone and hepcidin.

Anaemia (low haemoglobin levels) can develop in a number of conditions, including chronic kidney disease (CKD) and intestinal conditions (e.g. inflammatory bowel disease, intestinal failure). Intravenous iron can be given to patients with these conditions to help correct their aneaemia. However, intravenous iron has been associated with the development of low phosphate levels - hypophophosphataemia. The aim of this study is to determine potential causes of hypophosphataemia following administration of intravenous iron.

Anemia is the most common complication of liver cirrhosis and is seen in 75% of cases. The etiology of anemia in liver disease is diverse and often multi-factorial. Given the diverse and sometimes multifactorial etiology of cirrhosis, it is difficult to determine the exact cause of anemia in these groups of patients. The most common type of anemia encountered in liver cirrhosis is normocytic normochromic anemia, attributable to the chronic inflammatory state. The key question in management of anemia in patients with liver disease which specific factor needs to be corrected to restore hemoglobin levels and improve overall clinical status and improve severity scores.
