Filter by:Irritable Bowel Syndrome (IBS) is a common disorder, defined by symptom-based diagnostic criteria. The pathogenesis is multifactorial and gut motor dysfunction is considered to be a contributing factor. Changes in motor patterns in the small bowel in IBS patients are quantitative rather than qualitative with no distinct patterns to distinguish patients from healthy individuals. Changes in motor patterns can affect transit of bowel contents. Indeed, variation in intestinal transit was reported in patients with IBS. Lubiprostone is a novel agent that is Food and Drug Administration (FDA) approved for the treatment of chronic constipation. More recently 2 randomized double-blind, placebo-controlled trials showed the drug to be effective in relieving symptoms in patients with constipation-predominant Irritable Bowel Syndrome (C-IBS), resulting in approval for female patients with C-IBS at a dose of 8 micrograms twice a day. The investigators hypothesize that lubiprostone works not just as a laxative, but by actually altering motility patterns in the small intestine of female patients with C-IBS. These alterations can be measured through High Resolution Manometry (HRM), a new technique that uses catheters with multiple closely spaced sensors and special software that uses color schemes to portray a pressure gradient. This technique allows a detailed assessment of the direction and spread of contractions. The investigators would like to use HRM to see if lubiprostone affects intestinal contractions by giving blinded participants lubiprostone and placebo while they are undergoing High Resolution Manometry and seeing if any changes in contractions occur. Participants will be recruited from investigator's clinic. If interested, potential subjects will be provided with a copy of the consent form for review. Patients will be informed that after they have had an opportunity to review the consent form, they may contact the study team to further discuss the research and address any questions/concerns they have. Participants will undergo a screening visit and a manometry visit. During the screening visit investigators will determine eligibility, including application of inclusion/exclusion criteria and administration of a pregnancy test. Then during the manometry visit patients will receive two capsules, lubiprostone and placebo, three hours apart during HRM. Patients will receive each capsule only once and will not know which order they're receiving them in.
The objective of this study is to evaluate the clinical efficacy and safety of SPM962 in patients with restless legs syndrome (RLS) with once-daily repeated doses of 4.5mg and 6.75mg during a 13-week dose-titration and maintenance period. This is a multi-center, randomized, placebo-controlled, double-blind, 3-armed parallel group comparison study. Efficacy will be determined by investigating the superiority of SPM962 to placebo in terms of the primary efficacy variable, change in International Restless Legs Syndrome Rating Scale (IRLS) total score from baseline to the end of the dose-maintenance period.
The purpose of this study is to determine if short term use of rivastigmine can improve functional abilities (for example, language, memory, and executive function) in adolescents with Down syndrome.
This phase II trial studies how well azacitidine works in treating patients with relapsed myelodysplastic syndrome (MDS), chronic myelomonocytic leukemia (CMML), or acute myeloid leukemia (AML) who have undergone stem cell transplant. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.
The exact etiology of CTS remains yet unknown. A rise in carpal tunnel pressure is well documented, but why this phenomenon occurs is yet unknown in most patients. There is an absolute or relative narrowing of the carpal tunnel, which results in a compression of the median nerve. The investigators postulate, that a stiffer flexor retinaculum (roof of carpal tunnel) will be less compliant. As a consequence of this stiffer retinaculum the pressure in the carpal tunnel will rise more quickly in stiff patients resulting in CTS-complaints. A relation between connective tissue composition and joint stiffness is proven. This relationship possibly extends to a relation between stiffness of the skin, joint stiffness and the prevalence of CTS.
The purpose of this study is to determine the safety of lenalidomide and markers for disease progression in the treatment of IPSS low- or intermediate-1 risk MDS with isolated del5q.
Neurotrophins (NTs) constitute a family of growth factors, which regulated differentiation, proliferation, and survival of both neuronal cells and astrocytes. In recent years, several studies have provided evidences that the cellular effects of NGF " Nerve Growth Factor ", BDNF " Brain-Derived Neurotrophic Factor " and NT-3 are not limited to the nervous system. Indeed, neurotrophins and their receptors are widely expressed on non neuronal cells. Data concerning the implication of NTs and their receptors in the immune system maturation and in the regulation of normal and pathological immune responses are numerous and suggest the existence of a specific "neuro-immunomodulation" through these neuropeptides. The aim of the study is to compare Sjögren's syndrome systemic activity to seric, lymphocytic and conjunctival levels of NTs (i.e NGF, BDNF and NT-3). A preliminary study has previously pointed out the link between high BDNF seric levels and Sjögren's systemic activity. The increased levels of BDNF were correlated to T cell activation. A similar correlation between high NGF level and hypergammaglobulinemia was also pointed out.
The study project can be divided into two parts: (1) health screening for the community and (2) clinical diagnosis and treatment for patients at National Referral Hospital (NRH) in Solomon islands. The health screening includes a questionnaire, stool parasitic screening and blood laboratory tests. A total of 800 subjects will participate in this study. The collected samples are venous blood (20 ml/per subject) and stool in order to conduct the related tests mentioned above. As for the collection of target patients, KMUH will cooperate with NRH to collect two kinds of blood samples: the blood samples of confirmed malarial cases and those of cases suspicious of Flaviviral, Alpha-viral, Rickettsial, and Leptospiral infections. The expected received cases are 600 each year. The venous blood samples (20 ml/per subject) will be used to conduct related tests mentioned above. At the same time, the subjects will also have to fill out a related questionnaire which includes height, weight, waist line, heath behavior and habit, and past history, etc.
The aim of the trial is to assess coronary artery reactivity using adenosine-induced coronary flow reserve (CFR) by transthoracic echocardiography in patients with Bio-active stent (BAS) and Everolimus-eluting stent (EES) distal to the original culprit lesion at 6-8 months.
In Serono Study 24380, the antecedent protocol to Study 25373, patients were randomly assigned in a 3.0-to-1.0 ratio to Groups A and B. All patients in Group A received recombinant human growth hormone (Serostim®) 4 mg daily (the "induction" phase) for the first 12 weeks, and then were re-randomized to receive either placebo or Serostim 2 mg on alternate days (roughly equivalent to 1 mg daily) during Weeks 12-36 (the "maintenance" phase). All patients in Group B initially received placebo from baseline to Week 24, and then received Serostim® 4 mg daily from Weeks 24 to 36 (Grunfeld, 2007). In the follow-up Study 25373, any subject who was enrolled in Serono Study 24380 and was assigned to Group A, who fully completed all study visits without a major protocol violation, was eligible to enroll to receive re-treatment with Serostim at a dose of 4 mg daily for 12 weeks. During study 25373, safety was monitored by recording of adverse events and measurement of urinalysis and laboratory blood tests to assess fasting glucose, fasting insulin, and routine biochemistry and hematology parameters. At Week 12 or at the time of study termination, subjects underwent re-assessment of body composition via anthropometry measurements and dual photon absorptiometry (DXA) scanning. In addition, at study termination, measurements of insulin-like growth factor I (IGF-I), insulin-like growth binding protein 3 (IGFBP-3), fasting lipid profile, and oral glucose tolerance testing were obtained.
