Filter by:The "National Transfusion Treatment Survey in patients with sickle cell disease (SCD)" is a prospective longitudinal systemic study that was created in order to evaluate the therapeutic approach, mainly transfusional, in patients affected by SCD throughout Italy and to improve the quality of care and implement research. The survey will evaluate all patients affected by different forms of sickle cell disease (HbS homozygosis, Thalassoso-drepanocytosis, HbS / HbC compound heterozygosis, other possible genetic compounds). Patients will be selected according with a SCD diagnosis confirmed by standardized biochemical criteria or by DNA analysis. Patients will be excluded from the study who do not meet the these requirements, who are unable to understand the protocol or able to give informed consent in the absence of any legal representative. All data will be collected through a standard web-based application, which will be completed by the responsable investigator or by sub-investigators selected by each center, after registration on the site providing personal data and indicating the affiliation structure. All data will be subsequently encrypted by the Central Server. The operator will subsequently be able to access the patient's clinical data to perform the updates, in order to follow the patient's clinical evolution over time. The study will not involve any additional tests compared to the routine of patient control.
Patients with sickle cell disease (SCD) and cancer often have complicated courses while hospitalized and often deal with pain, anxiety and depression. Advances in the field of technology provide potential avenues for innovative and improved care models for our patients. Virtual reality (VR) has been recently utilized to improve anxiety and pain in a variety of patient populations including children undergoing elective surgery and children experiencing intravenous cannulation in the Emergency Department. Patients with SCD and cancer, both adults and children, are a group of patients that can benefit from VR as part of their care. Over the past four years, our team has successfully implemented several self-developed mobile applications ("apps") for our patients, in addition to integrating objective data (heart rate, activity, stress) from wearable activity trackers. The investigators now propose implementing a feasibility study followed by a pilot study and randomized-controlled trial of the use of VR in patients with SCD and cancer. The investigators plan to assess pain and anxiety prior to the session as well as following the session in hospitalized patients and outpatients with SCD and cancer. The sessions will include a ten-minute relaxation response introductory narrative segment (deep breathing and mindfulness) followed by a ten-minute narrated and immersive VR. Heart rate will be tracked using an Apple iWatch for 30 minutes prior to the session, during the session, and following the session. We anticipate VR will not only be a feasible method to provide non-pharmacologic treatment, but will also significantly reduce pain and anxiety.
This study will test the hypothesis that Heart Rate Variability Biofeedback (HRV-B) restores autonomic balance and reduces pain and other symptoms among patients with sickle cell disease (SCD).The specific aims of this study are to: (1) conduct a randomized, wait list controlled, pilot intervention trial to determine whether HRV-B increases HRV coherence among SCD participants (minimum N of 30, up to 50 total); (2) determine whether HRV-B reduces pain, stress, fatigue, depression or insomnia among SCD participants; and (3) determine whether increases in HRV coherence are associated improvements in pain, stress, fatigue, depression, or sleep among study participants.
The goal of this study is to specify the interventions, implementation strategies and control conditions from the Sickle Cell Disease Implementation Consortium (SCDIC) using a mixed-methods approach to study site materials and conduct semi-structured qualitative interviews with site representatives (N=3 per site). We focused on the Emergency Department Working Group from the SCDIC working groups.
Sickle Cell Disease (SCD) is a rare disease occurring in an estimated 100,000 individuals, often poor and underserved, in the US. Silent and overt strokes contribute significantly to morbidity in adults with SCD, resulting in functional impairment, challenges with school and job performance, and premature death. Five NIH-funded randomized controlled trials have identified therapies to prevent silent and overt strokes in children with SCD, including monthly blood transfusion therapy (for preventing initial and recurrent strokes) and hydroxyurea (for preventing initial strokes). Despite the observation that at least 99% of children with SCD in high-income countries reach adulthood, and approximately 60% of adults will experience one or more strokes (~50% with silent strokes and ~10% with overt strokes), no stroke trials have established therapeutic approaches for adults with SCD. For adults with SCD, inadequate evidence-based guidelines exist for secondary stroke prevention strategies. Applying stroke prevention strategies in children may not be effective for stroke prevention in adults with SCD, particularly given the high rate of co-morbidities. Identifying subgroups of adults with SCD and higher incidence coupled with the contribution of established stroke risk factors in the general population (smoking, diabetes, obesity, renal disease) will provide the requisite data required for the first-ever phase III clinical trials focused on secondary stroke prevention in adults.
Despite important advances in the current understanding of sickle cell vaso-occlusion, the basis of its control and prevention remain partially unknown. The primary purpose is to test the hypothesis of a control of the sickle cell vaso-cocclusive (VOC) process by the anti band 3 antibodies by assessing the level of these antibodies in the steady state and during the crises in SCA patients. To assess the relationship between the level of band 3 antibodies, the oxidation status, the expression of microparticles and the hemorheological alterations of the sickle red cells (SS RBs), the severity of VOC.
pulmonary arterial hypertension (PAH) has been reported with a prevalence of approximately 30% in adult sickle cell disease (SCD) patients, with an increased mortality in SCD patients with PAH, compared with those without PAH. The identification of several hemolysis biomarkers such as lactate dehydrogenase, bilirubin, reticulocytes or hemoglobin level, has clearly documented a link between hemolysis and PAH. However, other physiopathological mechanisms may be involved to explain PAH in these patients, such as pulmonary thromboembolism, pulmonary fibrosis or left heart diastolic and / or systolic dysfunction. The investigators suggest studying HTAP in patient's presenting the most frequent both drepanocytic syndromes, SS and SC and homogeneous in their medical coverage and the association between HTAP risk and specific SCD complications.
This is a Phase II study for the use of T-cell replete reduced intensity conditioning (RIC) haploidentical donor allogeneic hematopoietic cell transplantation (HaploHCT) for individuals with high-risk non-malignant diseases who lack a suitable HLA-matched sibling donor.
Acute vaso-occlusive crisis (VOC) is the most common complication in patients with sickle cell disease (SCD) and pain related to VOC is often inadequately treated. This is a phase II randomized controlled clinical trial evaluating the efficacy of virtual reality technology when added to standard pain management for patients with sickle cell disease who are experiencing acute pain crisis in the ambulatory care setting. Patients will be randomized to receive either standard management only or standard management in addition to virtual reality therapy. The remainder of care for the painful event will continue per institutional standards according to clinical indication, including reassessment and documentation of pain and additional doses of pain medicines by intravenous (IV) or oral route. Pain scores and opioid requirement will be measured and compared across treatment arms, along with the outcomes of discharge from clinic versus admission to the inpatient unit. PRIMARY OBJECTIVE: To assess the efficacy of virtual reality (VR) technology in reducing pain at 30 minutes after intervention during an acute vaso-occlusive crisis in patients with sickle cell disease. Primary endpoint will be change in pain scores in Standard versus VR arms, between the first pain assessment at the time of presentation and the subsequent pain assessments up to 30 minutes after intervention. Secondary Objectives: - To compare total opioid consumption from the time of presentation to the time of discharge from acute care setting in Standard versus VR arms. - To assess the efficacy of virtual reality (VR) technology in reducing pain at 60 minutes after the first IV medication administered or 60 minutes after completion VR during an acute vaso-occlusive crisis in patients with sickle cell disease.
BIOCADRE is a CADRE substudy and aims to characterize more precisely the sickle cell patients with extreme phenotype.
