Active clinical trials for "Anemia, Sickle Cell"

The purpose of this study is to evaluate the effect of Virtual Reality induced Hypnosis on patients' pain scores, anxiety and the use of analgesics during a vaso-occlusive crisis

The objective of this study is to determine the seroprevalence of severe acute respiratory syndrome-CoV-2 in unvaccinated sickle cell patients living in an area with high viral circulation and at risk of high viral transmission, after the 4th epidemic wave of COVID-19 in Ile-de -France, over a period of 3 months (for example, last quarter of 2021).

The investigators propose to adopt sustainable community networks (in this case churches) to implement an integrated community-based screening that incorporates mobile health technology (mHealth) to make prenatal test results available at the point-of-delivery to guide medical management.

Prolong proposes to test safety, tolerability and pharmacokinetics of SANGUINATE™ in sickle cell disease (SCD) patients. Prolong's preclinical studies showed that SANGUINATE™ was safe in a number of different animal models and toxicology studies. In this Phase I trial, Prolong will test whether it is also safe and tolerable in sickle cell patients. The study will be conducted in 15 adult (>18 years) patients.

The investigators propose to evaluate etCO in patients with HbSS, HbSC, and HbS-beta thalassemia during routine clinic visits, and longitudinally. Our goal is to know whether etCO differs amongst subjects with different sickle cell syndrome genotypes, and whether it is a stable marker of hemolytic rate, as reflected in routine labs obtained for clinical care (including total hemoglobin, reticulocyte count, lactate dehydrogenase, and, when sampled, total and direct bilirubin). We hope to establish whether this inexpensive and non-invasive test faithfully reflects hemolytic parameters in sickle cell syndromes.

This was a retrospective cohort study using secondary data from member sites of the National Alliance of Sickle Cell Centers (NASCC) with at least five patients who initiated crizanlizumab. Patients who were prescribed crizanlizumab were included in the cohort.

To describe change in ACR and eGFR during study follow-up, and assesss the association of baseline and change in ACR and eGFR, with progression of kidney failure and/or all-cause mortality.

Sickle cell disease (SCD) necessitates a paediatric treatment plan that considers the influence of psychological, family and intercultural factors. At the Louis-Mourier Hospital (APHP) in Colombes, France, a paediatric-psychological partnership where a clinical psychologist accompanies the paediatrician at programmed consultations was introduced. The psychological repercussions of SCD were assessed among children and their parents treated in Colombes and in two other paediatric units without a paediatric-psychological partnership.

Three methods are actually used in newborn screening for sickle cell disease (SCD) in France: isoelectric focusing, high performance liquid chromatography and capillary electrophoresis. New technologies are currently under development such as Matrix Assisted Laser Desorption Ionisation - Time of Flight (MALDI-TOF) and tandem mass spectrometry (MS/MS) using the SpOtOn Diagnostics Reagent Kit available in United Kingdom only. Zentech company (Liège, Belgium) is developing a package for SCD newborn screening using MS/MS technology. The main objective of the present study will be to compare this new technique with the technique actually used in the hospital center of Lille (sub-contractor for SCD newborn screening of Lyon) and the haemoglobin analysis to test its accuracy (sensitivity and specificity).

Background: Painful vasoocclusive crisis (VOC) occurs in people with sickle cell disease (SCD). People with VOC have many visits to the hospital. About 10 30 percent of these people will go on to develop acute chest syndrome (ACS). ACS can cause further ill health. It can also cause death. Researchers want to find ways to diagnose ACS more quickly. To do this, they want to use stored blood samples and scans from a study (the DeNOVO trial) that was closed in 2015. They want to see if scans and samples taken of people with VOC who later developed ACS could help diagnose ACS faster. The data of people in the DeNOVO study who did not develop ACS will serve as controls. Objectives: To look at data from the DeNOVO trial to find a way to diagnose ACS more quickly. Eligibility: People 10 85 years old who took part in NHLBI Protocol number 05-H-0019 (the DeNOVO trial). The trial lasted from 2004 to 2008. The study was closed in November 2015. Design: Scans and intact, frozen samples from a study that was closed in 2015 will be studied. No new participants will be enrolled. ...
