Filter by:The University of Illinois Health and Health Sciences System (UI Health) developed an integrated care management quality improvement model designed to provide comprehensive care coordination for Medicaid insured minority children and young adults with chronic health conditions living in Chicago. This program, called CHECK (Coordinated HEalthcare for Complex Kids), targeted children and young adults with chronic disease.
In this prospective observational study among sickle cell children aged 7 to 17 years, who face many experience of pain, pain will be assessed during incentive spirometry sessions. Then a relation between, inspiratory volume, pain and the length of hospital stay will be identified . Currently, there is no scientific data regarding the correlation between acute pain during vaso-occlusive crisis, incentive spirometry and the impact on length of hospital stay. In fact, physiotherapist experience's in the pediatric department suggests that the pain expressed by the child is not always correlated with inspiratory capacity. The absence of pain is one of the reasons for hospital discharge after decompensation in patients with sickle cell disease. However, no scientific study has linked incentive spirometry, pain and length of hospital stay. Investigator assume that these children underestimate the real pain and its impact on breathing pattern, and presume that the maximal inspiratory volume during spirometry sessions will be a better reflect of pain than standard pain scale. The aim of this study is to show that inspiratory volume would be a better indicator of discharge from hospitalization than actual pain scales.
Pain is the most common component of the morbidity seen in sickle cell disease (SCD), and may be acute or chronic. It is most commonly acute and a result of the hallmark vaso-occlusive episodes of the disease. Many patients however suffer from chronic pain - defined as pain lasting over three months- with neuropathic pain being a component of chronic pain. Neuropathic pain significantly contributes to the chronicity and morbidity of pain in SCD patients, and is an inadequately managed complication. There is a paucity of literature covering this area, and it has never been examined in the Jamaican population. The main objective of this study is to determine the epidemiology of pain among Jamaicans with SCD, and determine the prevalence of chronic and neuropathic pain among these patients. A second objective is to validate, using gold-standard measures, screening tools to determine neuropathic pain among the study population. This cross-sectional study will investigate the prevalence of neuropathic pain and complications in a sample of persons with SCD in Jamaica aged 14 years and older, with a validation sub-study to be conducted on a random 20 percent of the sample. With improved diagnosis of neuropathic pain, clinicians may potentially improve the management of pain in SCD, as clinicians should be able to direct our treatment toward medications and non-pharmacological methods of pain relief that are more specific for neuropathic pain. All data will be de-identified and maintained in a secure database, with access limited to key personnel. There is very minimal risk to participants.
Background: Sickle Cell Disease (SCD) is an inherited blood disorder. People with SCD have abnormal hemoglobin in their red blood cells. Researchers are investigating the safety and efficacy of an investigational medicine called AG-348 (mitapivat sulfate) to determine if it will help people with SCD. Objective: To test the tolerability and safety of AG-348 in people with SCD. Eligibility: People ages 18 and older with SCD. Design: Participants will have 8 visits over approximately 14 weeks. At the first visit participants will be screened with a medical history, a physical exam, blood and urine testing, and an EKG. During the following 5 visits, participants will stay at the clinic for 1 night each. Participants will take study drug in increasing doses up to visit 6, after which the drug will be tapered off. All visits will include physical exam, blood, and urine tests. The last visit will occur 4 weeks after stopping the drug. Participants will provide DNA from the blood samples they provide. The DNA will be tested for an inherited gene that can cause differences in response to the study drug. Researchers may also test other genes to see if they can find any genes that interact with SCD.
TAK-755 (previously known as SHP655) is a medicine used to treat sickle cell disease (SCD). The main aim of the study is to measure the safety and tolerability of TAK-755 in SCD participants. Study participants will receive TAK-755 or placebo on Day 1. Their SCD will be treated by their doctor according to their doctor's usual clinical practice. During the study, participants will be asked to follow-up on 13 days following SHP655 or placebo administration for safety assessment. Maximum duration of participation is expected to be about 2 months.
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).
Sickle cell disease is the most common genetic disease in the world. It results in the synthesis of an abnormal hemoglobin (HbS) which, in its deoxygenated form, polymerizes and causes structural changes in red blood cells (RBCs). They become more rigid and less deformable. The fragility of sickle-cell RBCs leads to their massive destruction, leading to chronic anemia (i.e. low hemoglobin in the blood) and to low tissue oxygenation. More rigid and less deformable, sickle-shaped RBCs tend to obstruct microvessels, leading to particularly painful vaso-occlusive crisis (VOC), which can cause organ failure (spleen, kidneys, brain, lungs, heart, liver, bone ...) and patient's lifethreatning. A preliminary work on red blood cells of sickle cell patients showed alteration of a parameter measuring the overall deformability of RBCs by assessing the nature of their movement in a shear flow. This parameter is altered sickle cell patients at basal state compared to a population of healthy individuals. This alteration is increased when sickle cell patients are in crisis. The main objective of this project is to study the evolution of this parameter in sickle cell patients according to their health status (basal state vs vaso-occlusive crisis). The investigators hypothesize that the alteration of the RBC deformability parameter is significant before symptoms of vaso-occlusive crisis (several hours to several days). The main objective is a weekly analysis of the evolution of the parameter in 30 sickle cell patients (SS or SB°) in the basal state and daily in at least 6 patients at the beginning, during and just after a vaso-occlusive crisis. The comparison between the parameter measured in a subject in the basal state and in the same subject in crisis will be performed. The criteria for the presence of a vaso-occlusive crisis were: the appearance of a attacks of pain affecting at least two territories +/- fever> 38.3 +/- dyspnea and / or sputum. The investigators will differentiate the moderate VOC managed at home with low-level analgesics and VOC requiring hospitalization. The number of days of hospitalization, the occurrence of thrombotic complications, the degree of anemia and hemolysis will be noted. The measurement of the parameter will be performed on a capillary sampling of 40 microliters performed at the fingertip, weekly outside crises and daily when a crisis occurs.
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.
Background: Sickle cell disease is a common inherited blood disorder. Kidney disease is a major cause of problems in people with sickle cell disease. In order to identify kidney problems early and stop the progression of kidney disease, doctors need the most accurate tests to check kidney function. Researchers hope to understand more about how to test for kidney disease in people with sickle cell disease. Objective: To determine which of two different lab tests is the best to measure kidney function in adults with sickle cell disease. Eligibility: People 18 years and older who have sickle cell disease Design: Participants will be screened with a medical history and blood tests. Participants will have up to 3 visits. Participants will collect their urine in a special container over 24 hours. At the first visit, participants will have blood tests. They will bring their container of urine to the visit. They will have an iothalamate test. For the test, they will get a catheter: a small tube will be inserted into a vein. A special contract agent will be injected into the vein. Blood will be collected over the next 4 hours to test kidney function. Participants will return the next day for a second visit. They will have blood tests. They will have an MRI. For the MRI, they will like on a table that slides into a machine that takes pictures of the kidneys. They may have the MRI in a third visit. ...
Sickle cell disease is very common in Nigeria. Early diagnosis is important to prevent or reduce serious complications from the disease and to enable children stay healthy. To this end, the investigators would like to test a new, simple and quick device called the HemeChip to determine if it can detect whether or not someone has sickle cell disease. The investigators will compare the results obtained with the HemeChip with a standard method of diagnosing sickle cell disease known as Isoelectric focusing (IEF) or High Performance Liquid Chromatography (HPLC).If the investigators show that the new device can differentiate between children who have sickle cell disease and those who don't as successfully as the IEF or HPLC, they estimate a sharp increase in the use of this device in many countries especially in Africa due to its lower cost
