Filter by:This is a multicenter, single-arm, non-interventional study (NIS) to confirm the safety and efficacy of eltrombopag in Anti-Thymocyte Globulin (ATG) treatment naive pediatric patients with aplastic anemia (AA).
To look at the safety and effectiveness of emapalumab for the treatment of prolonged severe cytopenia in participants with LBCL who receive CART.
The goal of this observational study is to evaluate the clinical efficacy of the transfusion of irradiated red blood cells, washed red blood cells, and leukocyte privative red blood cells, and to study the changes of inflammatory response before and after the transfusion of irradiated red blood cells, washed red blood cells, and leukocyte privative red blood cells in anemic neonates. The main questions it aims to answer are: - Objective evaluation of the advantages and disadvantages of transfusion of different blood products in the treatment of neonatal anemia from the clinical efficacy. - To provide objective basis for clinical rational use of blood in the selection of blood products. Participants will be transfused with fresh irradiated red blood cells, washed red blood cells, and leukocyte privative red blood cells respectively according to relevant clinical and laboratory indicators.
The prevalence of iron deficiency in pediatric cardiac surgery patients is not very well known. Iron deficiency can lead to anemia, higher transfusion rates and possibly higher complication rates. In this retrospective study, the iron status of all patients undergoing pediatric cardiac surgery at our institution between January 2019 and december 2023 will be analyzed. Together with iron status, transfusion requirements as well as complications will be recorded. Iron status will be reported with descriptive statistics, patients with or without iron deficiency will be compared using non-parametric tests.
The aim of this prospective, observational cohort study is to assess the impact of iron deficiency anaemia on the incidence of perioperative complications and the quality of recovery after surgery in patients undergoing colorectal cancer surgery. The main questions the study aims to answer are: - whether the presence of preoperative iron deficiency anaemia leads to a poorer quality of postoperative recovery in patients undergoing colorectal cancer surgery - whether different combinations of complete blood count parameters (red blood cell indices) could be suitable diagnostic tools for the detection of iron deficiency in the latent stage (without laboratory-confirmed anaemia) in colorectal cancer patients. Blood samples for laboratory analyses will be collected from each study patient admitted to the surgical ward one day prior to elective surgery and on the first postoperative day during the stay in the intensive care unit. The pre-operative laboratory analyses include a complete blood count and serum iron status parameters (iron concentration, ferritin concentration, TIBC, UIBC and TSAT). Laboratory parameters analysed on the first postoperative day include complete blood count, serum concentration of electrolytes (Na, K, Ca, Cl, Mg), serum concentration of urea and creatinine, parameters of haemostasis (aPTT, PT, INR), serum concentration of C-reactive protein and procalcitonin. Data about overall morbidity, intraoperative complications, quality of postoperative recovery, red blood cell transfusion rate, all-cause infection rate, antibiotic usage, as well as length of hospital stay will be collected. The researchers will compare the group of patients with iron deficiency anaemia, the group of patients with iron deficiency in the latent stage and the control group to determine whether patients with iron deficiency have a higher incidence of perioperative complications and impaired recovery after surgery. The researchers will investigate whether iron deficiency can be detected at an early stage, when anaemia is not yet present, by calculating various red blood cell indices.
Autoimmune cytopenias resistant to treatment are among the most common clinical manifestations observed in patients with congenital alterations of the immune system, such as primary immunodeficiencies (PI). The exact contribution of immune system alterations to the pathogenesis of autoimmune cytopenias has not yet been fully elucidated. Moreover, conventionally employed therapeutic strategies often fail, leading to increased healthcare costs, high morbidity, and even mortality. Therefore, there is a need to establish clinical guidelines for diagnosis and to identify early biomarkers capable of identifying individuals responsive to therapy. Thus, a systematic approach to the study of such pathologies will allow for the identification of early biomarkers and facilitate the development of targeted therapeutic strategies
Due to long-term dependence on platelet transfusion, some severe aplastic anemia (SAA) patients suffer platelet transfusion refractoriness (PTR). Unlike immune thrombocytopenia (ITP), glucocorticoids and human immunoglobulin (IVIg) are generally ineffective for PTR. Due to the lack of effective intervention methods, patients with PTR suffer increased platelet transfusions, bleeding events and treatment costs, prolonged hospital stays, and decreased survival rate. SAA with PTR has become a challenge for physicians. The experiment aims to explore the efficacy of rituximab in the treatment of SAA with PTR, and establish a new effective, safe treatment method with relatively low treatment cost.

ENROL, the European Rare Blood Disorders Platform has been conceived in the core of ERN-EuroBloodNet as an umbrella for both new and already existing registries on Rare Hematological Diseases (RHDs). ENROL aims at avoiding fragmentation of data by promoting the standards for patient registries' interoperability released by the EU RD platform. ENROL's principle is to maximize public benefit from data on RHDs opened up through the platform with the only restriction needed to guarantee patient rights and confidentiality, in agreement with EU regulations for cross-border sharing of personal data. Accordingly, ENROL will map the EU-level demographics, survival rates, diagnosis methods, genetic information, main clinical manifestations, and treatments in order to obtain epidemiological figures and identify trial cohorts for basic and clinical research. To this aim, ENROL will connect and facilitate the upgrading of existing RHD registries, while promoting the building of new ones when / where lacking. Target-driven actions will be carried out in collaboration with EURORDIS for educating patients and families about the benefits of enrolment in such registries, including different cultural and linguistic strategies. The standardized collection and monitoring of disease-specific healthcare outcomes through the ENROL user-friendly platform will determine how specialized care is delivered, where are the gaps in diagnosis, care, or treatment and where best to allocate financial, technical, or human resources. Moreover, it will allow for promoting research, especially for those issues that remain unanswered or sub-optimally addressed by the scientific community; furthermore, it will allow promoting clinical trials for new drugs. ENROL will enable the generation of evidence for better healthcare for RHD patients in the EU as the ultimate goal. ENROL officially started on 1st June 2020 with a duration of 36 months. ENROL is co-funded by the Health Programme of the European Union under the call for proposals HP-PJ-2019 on Rare disease registries for the European Reference Networks. GA number 947670
