Active clinical trials for "Down Syndrome"

This study involves the collection ocular lens tissue from individuals with Down syndrome and age-matched controls at the time of cataract surgery.

This prospective blinded study will assess the diagnostic capability of an informatics enhanced SNP based technology (Parental Support) to identify pregnant women who are carrying a fetus with an aneuploidy from fee floating DNA in the maternal blood.

Failure to thrive and difficulty gaining weight is a sign of uncompensated congestive heart failure (CHF). Infants with Trisomy 21 and complete atrioventricular canal defects (CAVC) frequently develop uncompensated CHF and weight gain failure pre-operatively. A weight of 5 kg has been suggested as optimal for timing of CAVC repair. A delay in surgical repair often occurs if weight gain stalls and reaches a plateau prior to reaching 5 kg. A retrospective review performed by Kogon, et al, of children undergoing surgery for VSD at CHOA at Egleston recently reported that age and weight at surgery may not, however, be associated with adverse surgical outcome. The purpose of this study is to determine the optimal timing for surgical correction of CAVC in Trisomy 21 infants based on reaching a plateau of failed weight gain despite maximal anti-congestive and nutritional therapy.

The Cognitive Neuroscience Section of the National Institute of Neurological Disorders and Stroke proposes to continue its cross-sectional and longitudinal studies of cerebral metabolism in frontal lobe dementias and atypical basal ganglia disorders. These studies include repeated assessments of neuropsychological and brain anatomical and metabolic function in subjects with these important and possibly related brain disorders.

This study will document the detection rate and false positive rate as well as failure rate of a new prenatal screening approach ('Smart NIPT') as described at www.vanadisdx.com and implemented in an academic laboratory with limited molecular testing experience. Testing will be performed on samples from a general risk pregnancy population, with additional high-risk cases added to improve confidence in the detection rate. Additional characteristics of this non-NGS test such as turn-around time, costs (equipment, training, per test), results reporting, fetal sex, fetal fraction, and quality measures will also be examined.

Survivors of acute lymphoblastic leukemia (ALL) are at risk for neurocognitive deficits, reduced educational and psychosocial outcomes, and lower quality of life. Neurocognitive assessment is frequently implemented during therapy and continued into survivorship to monitor functioning and to facilitate intervention. Children with Down Syndrome (DS) are at 10 to 20-fold increased risk for leukemia. Survival rates for leukemia patients with DS are comparable to or lower than patients without DS, however, these patients are at greater risk for treatment-related toxicities. Children with preexisting neurodevelopmental conditions, including DS, are systematically excluded from neurocognitive assessment on clinical trials, contributing to a gap in the investigators understanding of outcomes in these patients with preexisting neurocognitive vulnerability. The investigators propose a novel preliminary investigation of functional outcomes in children with DS and childhood leukemia. This study has implications for future treatment of leukemia patients with DS, and may generalize to leukemia patients with other predispositions or preexisting neurodevelopmental conditions (e.g., genetic disorders, acquired brain injury, autism, and epilepsy). Primary Objective: To describe neurocognitive and psychosocial outcomes in survivors of childhood leukemia with Down Syndrome using a novel assessment approach.

The objectives of the clinical study are to demonstrate the accuracy of our new NATUS diagnostic method to determine the genetic health of the developing fetuses in a multiple gestation pregnancy from a maternal blood sample. The long term goal of this study will be the development of a method of minimally invasive prenatal diagnosis that has a higher sensitivity and lower false positive rate in the intended population (e.g. multiple gestation pregnancies) than any currently available screening tests. This will result in fewer unnecessary amniocenteses and CVS procedures, which are associated with a risk of miscarriage.

Objective To access predictive values of the auxological parameters and indexes for risk of comorbid malformations in newborns with Down syndrome (DS) Study design In this cohort retrospective study, 141 newborns with proven trisomy 21 born at the Department of Gynecology and Obstetrics of the University of Split Hospital (1990 to 2015) were included. The data were obtained from the medical histories of mothers, infants and the delivery protocol. The objective was to access predictive values of the auxological parameters and indexes for risk of comorbid malformations in newborns with Down syndrome (DS) Conclusion Higher CI were found in hyportrophic (SGA) newborns with DS and indicated their intrauterine growth restriction with brain sparing and increased further risk of severe psychomotor retardation. The SGA newborns have lower parameters and indexes of nutritive status and significantly differed from eutrophic and hypertrophic newborns. These SGA newborns with DS have increased developmental risks and that requires further diagnostic attention.

Patients with trisomy 21 are in greater danger of developing caries. It has been hypothesized that adding silver nanoparticles to fluor varnishes could promote remineralization of the teeth. A split-plot randomized controlled trial will be performed to address this question.

The purpose of this research study is to determine which measures best capture cardiovascular disease (CVD) risk and type 2 diabetes (T2DM) risk in children and adolescents with Down syndrome (DS). We hypothesize that DS is associated with worse cardiometabolic risk factors for a given body mass index compared to controls. This difference arises at least in part, from increased fat tissue.
