Active clinical trials for "Syndrome"

Inflammation has been known to be a pivotal pathogenic mechanism of obesity-related disorders such as type 2 diabetes, metabolic syndrome and atherosclerosis. Adipose tissue functions as a major endocrine organ by adipokine mediated modulation of a number of signaling cascades in target tissues, that has pro-inflammatory or anti-inflammatory activities. Progranulin and CTRP3 are recently discovered novel adipokines. Therefore, the investigators tried to clarify the clinical meaning of these two adipokines in the subjects with or without metabolic syndrome

Marfan syndrome is an autosomal dominant connective tissue disorder caused by mutations in the fibrillin-1 gene (FBN1). Penetrance of FBN1 mutations is complete but intra and inter familial clinical expressivity is extremely variable. The underlying mechanisms for variability are not understood. An interesting mechanism is that the expression level of the wild type and/or mutated allele may play a role in the determination of variability. Principal objective: To evaluate in Marfan patients, if FBN1 expression level (non-mutated or mutated allele) modulates the clinical expression of the disease. Judgment criteria : Correlation allelic expression level-phenotype Perspectives : To search the predictive factors of severity in order to ameliorate precocity of taking care.

The purpose of this study is to define subgroups of patients with somatoform disorders due to DSM-IV by immunological, psychological and genetic characterization.

Polycystic ovary syndrome (PCOS) is an extremely common disorder in women of reproductive age. Diagnosis of PCOS is principally based on clinical and physical findings. Diagnostic criteria and PCOS definitions used by clinicians and researchers are almost as heterogeneous as the syndrome. This first part of study is determine whether genetic polymorphisms influence hormonal and metabolic characteristics in Taiwanese patients with PCOS and controls. Furthermore, women with PCOS were reported with high risk of cardiovascular disease, the investigators planned to calculate the difference of carotid intima-media thickness (IMT) and B-type natriuretic peptide (BNP) between women with PCOS and normal control to determine the premature atherosclerosis of women with PCOS.

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 prognosis of rheumatic diseases has improved considerably with development of therapy. However, infections are considered the most important cause of morbidity and mortality in this group of patients. One of the ways to prevent such complications is vaccination. In 2009, a new pandemic strain of influenza virus (A/H1N1/2009) has emerged raising major concerns for public health. Patients under immunosuppressive therapy have indication for immunization against influenza virus H1N1. There are, however, concerns about possibility of reactivation of autoimmune diseases, determine adverse events and insufficient immunogenicity in these patients. The lack of studies evaluating the efficacy and safety of the vaccine against influenza A(H1N1)/2009 in these rheumatic patients led to the development of this research. The objectives of this study are to evaluate the humoral response and safety of the vaccine virus A(H1N1)/2009 in immunosuppressed patients with rheumatic diseases compared to healthy controls. We have recruited 400 patients with rheumatoid arthritis, 350 with spondyloarthritis, 1000 with systemic lupus erythematosus (SLE), 150 with dermatomyositis (DM), 100 with mixed connective tissue disease, 150 with systemic vasculitis, 250 with systemic sclerosis (SSc) , 100 with Sjögren's syndrome, 100 with antiphospholipid syndrome, 100 patients with juvenile idiopathic arthritis, 80 with juvenile SLE, and 80 with juvenile DM, followed at our Rheumatology Outpatient Division and Unit Pediatric Rheumatology Children's Institute, HC-FMUSP. The control group was recruited were 200 healthy employees of ICHC-FMUSP. Informed consent was obtained from all participants and the study was approved by the Local Ethical Committee. All subjects were vaccinated against influenza virus A/(H1N1)/2009 (vaccine approved and supplied by Instituto Butantan-São Paulo). Blood samples was collected to measure levels of antibodies inhibiting hemagglutination by influenza virus A (H1N1)/2009 immediately prior to vaccination and 21 to 28 days after vaccination., Participants fulfilled a questionnaire on the immediate side effects of the vaccine. All patients with rheumatoid arthritis, spondyloarthritis, SLE, DM, systemic vasculitis, juvenile idiopathic arthritis, juvenile SLE, and DM were assessed before and 21 days after vaccination for clinical, laboratory parameters of disease activity as well as treatment. Continuous variables will be compared by t-test to evaluate differences between patients with rheumatic diseases versus healthy controls. Differences between categorical variables will be evaluated using the chi-square or Fisher exact test. Statistical significance was set at p<0.05.

Serotonin has recently been identified as a major regulator of bone formation. Gut-derived serotonin inhibits bone formation, and early animal studies have shown that inhibition of gut-derived serotonin has anabolic effects on bone in ovariectomised rodents. This pathway has potential to be developed as a new anabolic treatment for osteoporosis in humans. Carcinoid neuro-endocrine tumours produce very high levels of serotonin, and so it might be expected that patients with carcinoid disease would have reduced bone formation, low bone mass and fractures. However, this has not been apparent in clinical practice. There may be a discrepancy between rodent models and human disease. This study aims to identify whether patients with carcinoid disease have reduced bone mass, reduced bone formation or high fracture rates. The investigators will conduct a cross-sectional observational case-control study of patients with carcinoid disease in the Sheffield neuro-endocrine tumour clinic and gender-, age- and body mass index (BMI)-matched controls.

The purpose of this study is to investigate the overall response rate (ORR) and safety when treating patients with myelodysplastic syndrome with decitabine. Decitabine is to be administered as long as there is evidence of clinical benefit.

Rational: Intellivent is a ventilation mode completely automated which controls ventilation and oxygenation parameters. Safety and performance of IntelliVent has still been demonstrated in post operative heart surgery for patient with a controlled ventilation on short period (2 to 4 hours). This feasibility study evaluate the use of Intellivent for Intensive care unit patients from intubation to coming off. Primary objective : Compare parameters which have been selected by automated mod (Intellivent) to those selected by clinical practitioner in a conventional mode Secondary objectives: Record oxygenation , gaseous interchange and ventilation parameters. Record complications, number of manual adjustments and prognostic signs. Methodology: Patients in the intensive care unit who need invasive ventilation. They will be included after a detailed information (information note). Oxygenation and ventilation parameters will be recorded 2 times by day from intubation to coming off. The investigator in charge will determine daily at the bedside of the patient the adjustments he should make in a conventional mode. These adjustments will be compared to the IntelliVent automated adjustments. Experimental study, observational, prospective, comparative, opened, monocentric in an intensive care unit. Number of patients: 100

Patellar subluxation is a common disorder that may cause patellofemoral pain syndrome. The efficiency of patellar taping in the treatment of patellofemoral pain syndrome has been reported good outcomes in most patients. However, some studies reported less effective in patients with higher body mass index, larger lateral patellofemoral angle, and smaller Q angle. The investigators hypothesized that femoral internal rotation is a negative factor to the patellar taping. The investigators enroll consecutive 100 patients with anterior knee pain and radiographic evidence of patellar subluxation. The investigators determine femoral rotation via physical examination. The visual analogue scale was evaluate to compare the result between the those with and without femoral internal rotation.
