The purpose of this study is to determine if choline bitartrate can be administered daily to children with prenatal alcohol exposure, ages 2.5 to 5, as a potential treatment for brain development and cognitive functioning.
This study may provide information that may serve as the foundation for a larger research study to address issues regarding the causes, diagnosis, and treatment of osteoporosis in the Down syndrome patient population.
Creatine supplementation in RTT: a randomized controlled trial Rett Syndrome (RTT) is a neurodevelopmental disorder characterised by apparently normal early development (stage 1 of RTT) followed by loss of purposeful hand use, distinctive hand stereotypes, slow brain growth, loss of language, respiratory irregularities, gastrointestinal disturbances, gait abnormalities, seizures, and mental retardation. These symptoms typically appear between 6 and 18 months of age (stage 2). Subsequently, there is gradual stabilisation of severe mental retardation and motor compromise (stage 3). The majority (70% to 80%) of patients show mutations in the methyl-CpG-binding-protein-2 (MeCP2) gene, located on chromosome Xq28. MeCP2 encodes a transcription repressor protein that is ubiquitously expressed in all tissues. As RTT primarily affects females, only very few males with mutations in MeCP2 have been identified. Mutations in MeCP2 have also been identified in children with X-linked mental retardation, autism and a clinical phenotype that resembles Angelman Syndrome. The aim of this study is to investigate the effects of a dietary supplement on the biochemical and clinical parameter of RTT. About 80 % of labile methyl groups generated through the re-methylation cycle are used for the synthesis of creatine within the human organism. Supplementation of creatine will therefore increase the availability of labile methyl groups for different methylation reactions including methylation of DNA. The study will be double blind and cross-over. The patients will get creatine monophosphate (200 mg/kg/d in three dosages per day) or placebo. After 6 months and a wash-out period of 4 weeks the groups are changed for the next 6 months. All participants with RTT and mutations in MeCP2 will undergo physical and neurological exam, quantitative EEG, behavioral assessment, laboratory testing, and neuropsychological evaluations. Participants will have a follow-up after 3, 6, 10, 13 and 16 months (3 months after finishing the study), which will include similar assessments.
Clinically Characterized by the presence of chronic widespread pan and tenderness, Fibromyalgia (FM) is one of the most common "functional" syndromes. FM is currently conceived of as representing a prototype of central pain, i.e. a condition in which sensitization of the central nervous system results in a overall increase in the processing of painful stimuli, as well as an impairment of pain inhibition. This condition is responsible for significant a social and economic burden and is estimated to affect up to 5% of all women. The 1990 American College of Rheumatology (ACR) classification criteria for FM are the current standard for studying FM, and require the presence of widespread pain lasting over 3 months, as well as documentation of tenderness in at least 11 of 18 pre-defined "tender points. Multiple additional symptoms, which are not part of the classification criteria, include among others sleep disturbances, mood disturbances, cognitive dysfunction, vulvodynia, dysmenorrhea, sexual dysfunction and weight fluctuations. In addition, FM is well known to overlap both clinically and epidemiologically with an ever increasing number of other "functional" disorders, including irritable bowel syndrome (IBS), Temporomandibular joint disorder (TMJD), functional dyspepsia etc. In addition to the central symptom of pain, FM patients frequently complain of non- specific symptoms which are potentially autonomically - mediated. Thus, palpitations, fatigue and inability to stand for long periods of time are all common complaints. About 80-90 percent of FM patients have one or more symptoms associated with autonomic dysfunction. The most common of them is presyncope (62.5%), followed by syncope (12.5%), palpitations on standing (12.5%) and dizziness (12.5%) (14). Some of these symptoms overlap with those of the postural tachycardia syndrome (POTS). POTS is a common dysautonomia, characterized by remarkable increased heart rate during the assumption of the upright posture (>30 bpm). According to our experience, FM is found, at least, in 15% of POTS patients. But, no data exists about the incidence of POTS in patients with FM.The role of the autonomic nervous system (ANS) in initiating and maintaining the syndrome of FM has been studies (and debated) over the last decade. The ANS is an extremely complex system, regulating involuntary body functions, including heart rate, intestinal motility, urination, and sexual activity, among many other variables. Notably, the vagus has an inhibitory effect on pain. Deterioration in the vagal control is "associated" with increased pain sensation. Previous studies have indicated that FM patients may have an increase in sympathetic control over the cardiovascular system with a reciprocal decrease in parasympathetic control. High sympathetic tone is usually associated with a lower threshold to pain. But, the contribution of the ANS to the pathogenesis of FM syndrome remains unclear. Evidently, the ANS interacts with other components of the CNS in the pathogenesis of FM, including pain processing centers in the thalamus and amygdala, as well as with the hypothalamic-pituitary-adrenal (HPA) axis.
Primary Objective: - To demonstrate that lixisenatide can reduce cardiovascular morbidity and mortality [composite endpoint of cardiovascular (CV) death, non-fatal myocardial infarction (MI), non-fatal stroke, hospitalization for unstable angina] compared to placebo in type 2 diabetic patients who recently experienced an acute coronary syndrome (ACS) event. Secondary Objectives: To demonstrate that when compared to placebo, lixisenatide can reduce: - composite endpoint of cardiovascular death, non-fatal MI, non-fatal stroke, hospitalization for unstable angina, or hospitalization for heart failure - composite endpoint of cardiovascular death, non-fatal MI, non-fatal stroke, hospitalization for unstable angina, hospitalization for heart failure, or coronary revascularization procedure - urinary albumin excretion (based on the urinary albumin/creatinine ratio). To assess the safety and tolerability of lixisenatide.
To confirm that the combination therapy of rufinamide has superior efficacy compared to placebo in patients with Lennox-Gastaut syndrome.
This research study is studying identification of de novo Fanconi anemia in younger patients with newly diagnosed acute myeloid leukemia. Studying samples of tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to Fanconi anemia in patients with acute myeloid leukemia.
Gitelman syndrome is a rare renal disease where the kidneys are unable to normally retain some salts (sodium, potassium and magnesium). Main consequences of these renal leaks of salts are a tendency toward low blood pressure, hypokalemia and hypomagnesemia both contributing to cardiac and muscles symptoms.
The purpose of this study is to evaluate the efficacy of Losartan versus Atenolol in the progression of aortic dilatation in patients with Marfan syndrome.
