NCT ID: NCT02210741 Not yet recruiting - Graves Disease Clinical Trials

Next-generation Sequencing (NGS) of Peripheral Blood Immune Repertoire in Graves' Disease

Start date: August 2014
Phase: N/A
Study type: Observational

Graves' disease (MIM 27500) is the leading cause of hyperthyroidism worldwide. The prevalence of Graves' disease is quite high (2.7% in women), and there is solid evidence of genetic predisposition. Despite its clinical and scientific significance, Graves' disease is still mysterious in terms of its susceptibility genes or pathophysiological mechanisms. The immune repertoire, being the sum of T and B lymphocytes in a body at any given time, is both a snapshot and a historical record of a person's immune function. Thanks to the power of next-generation sequencing (NGS), massively parallel sequencing of the B cell and T cell receptors suddenly becomes plausible, and opens a door for many creative approaches to study immune related diseases. The ultimate goal of this project is to use both the NGS deep sequencing and immune repertoire experiment to perform Graves' disease sub-group genetic fine mapping, and to identify Graves' disease-specific T cell and B cell receptors. Furthermore, using the immune repertoire approach, investigators want to study the critical epitopes of thyroid auto-antigens, and to delineate the pathophysiological steps in various disease stages and in various sub-groups. Investigators expect to solve the immune repertoire of Graves' disease of different sub-group presentations and at various disease activity stages.

NCT ID: NCT02191072 Not yet recruiting - Urticaria Clinical Trials

Efficacy and Safety of Omalizumab in Patients With Severe Acute Urticaria

Start date: July 2014
Phase: N/A
Study type: Interventional

Efficacy of omalizumab in chronic spontaneous urticaria had been demonstrated in phase II and phase III studies. Clinical symptoms and signs had been significantly reduced with omalizumab as doses of 150 mg and 300 mg at 4-week intervals in patients with chronic spontaneous urticaria who remained symptomatic despite antihistamine treatment. Omalizumab had an onset of effect within a week after initiation. Thus, the investigators hypothesize that omalizumab will be effective in the treatment of severe acute urticaria as add on therapy with a fast onset of action. Objective:To investigate the efficacy and safety of omalizumab in the treatment of severe acute urticaria Study design: This prospective, interventional, single-arm open label study will recruit patients with severe acute urticaria from emergency departments, hospitalized and outpatient departments. The included patients will receive a single subcutaneous dose of 300mg omalizumab therapy. The efficacy of omalizumab will be evaluated by physical examination and assessed by Urticaria Activity Score (UAS) at baseline, 1 hour, Day 1, Day3, Day 7, and 6 weeks after omalizumab therapy. The frequency and severity of treatment-emergent adverse events will also be evaluated

NCT ID: NCT02178774 Not yet recruiting - Clinical trials for Diagnostic and Monitoring Anesthesiology Devices Associated With Adverse Incidents

Evaluation the Perfusion of Uterus and Lower Extremities During Cesarean Section With NIRS and Color Doppler

Start date: June 2014
Phase: N/A
Study type: Observational

Hypotension after spinal anesthesia for cesarean section is one of the most common perioperative issue, with an incidence up to 83%.Hypotension is mainly induced by the associated sympathetic blockade, with a drop of peripheral vascular resistance in the lower extremities and an increase in venous capacitance. Hypotension is a distress for both anesthesiologists and obstetricians as it endangers parturient's hemodynamics and compromises the uteroplacental blood flow. In clinical practice, there are several ways to treat hypotension after spinal anesthesia such as preloading with intravenous fluids and administrating ephedrine. Normotensive maternal blood pressure does neither guarantee the well-being of the fetus nor ensure the tissue perfusion of the parturient. Based on the anatomy and physiology basis, we hypothesize that uterine perfusion under spinal anesthesia would correlate with the perfusion of the lower extremities. To measure the perfusion of the lower extremities, we use a relative new tool, the non-invasive transcutaneous near infrared spectroscopy.

NCT ID: NCT02133677 Not yet recruiting - Clinical trials for Lung Cancer and Breast Cancer Patients With Brain Metastases

A Phase II Multi-center Pilot Study of Concurrent Temozolomide and Whole Brain Irradiation in Lung Cancer and Breast Cancer Patients With Brain Metastases

Start date: May 2014
Phase: Phase 2
Study type: Interventional

Brain metastasis (BM) is among the most feared complications in cancer because even small tumors may cause incapacitating neurologic symptoms. It is observed in more than 50% of patients with lung cancer and 15% to 25% of patients with breast cancer. Temozolomide (TMZ) is an oral alkylating agent that crosses blood-brain barrier (BBB). This pilot study aims to evaluate the efficacy, safety and tolerability of whole-brain radiotherapy (WBRT) plus concomitant TMZ in lung cancer and breast cancer patients with BM.

NCT ID: NCT02074202 Not yet recruiting - Clinical trials for Hepatocellular Carcinoma

To Evaluate the Efficacy and Safety of (18F-FCH) Comparing With (18F-FDG) for Detecting Hepatocellular Carcinoma

Start date: February 2014
Phase: Phase 3
Study type: Interventional

Liver cancer is a major cause of death among patients of east or southeast asian descent, as well as other population groups, notably in central and west Africa. Diagnosis of liver cancer requires a combination of several imaging techniques and biopsies. Despite this, diagnosis can remain inconclusive or difficult to establish in patients at risk for liver cancer. The purpose of this multi-center trial is to evaluate novel imaging methods developed to diagnose the most common form of liver cancer, hepatocellular carcinoma. We propose to use novel imaging probes that have been reported to bind to liver cancers but not benign liver lesions that can be confused with liver cancer. Two such imaging probes will be evaluated. 2-[18F]-fluoro-2-deoxy-D-glucose, called [18F]FDG, is a radioactive sugar that is widely used for cancer imaging with a device called positron emission tomography, or PET scans. We already know that [18F]FDG cannot detect some liver cancers that are slow growing. [18F]Fluorocholine ([18F]FCH), another molecule, has been recently reported to be highly effective at detecting liver cancer. In 2010, a French researcher reported 80-90% detection rate by using [18F]FCH alone or in combination with [18F]FDG. We will compare [18F]FCH and [18F]FDG in evaluating 150 patients over a period of two years. The results will be correlated with those of biopsies and clinical follow-up. This study will provide valuable data on whether these imaging agents can successfully differentiate malignant liver lesions from benign ones. It will also provide information about whether these imaging agents can successfully assess whether the cancer has spread outside the liver. It will provide data that will allow physicians to determine the optimal imaging protocol to properly diagnose liver cancer.

NCT ID: NCT02072265 Not yet recruiting - Clinical trials for Wound Healing Disturbance of Port-A

Using a Thermal Imaging System to Evaluate the Wound of Port-A and the Relationship Between Thermal Images and Infection

Start date: March 2014
Phase: N/A
Study type: Observational

Permanently implantable venous ports (Port-A) is very important to patients receiving chemotherapy. It not only provides a reliable route to administrate intravenous drugs, and it also requires minimal care when it is not in use. However, catheter related blood stream infection(CRBSI) is one of the serious complications of Port-A. The diagnosis of CRBSI relies on limited tools, including blood culture or symptoms and signs of active infection. In the stage of CRBSI, Port-A removal is necessary and pose the risk for the patients to re-implant the Port-A. Thus, it is crucial to early detect the infection and give appropriate treatment. Among the pathogens, some pathogens are related to skin contaminants. Before systemic spreading, these pathogens may colonize or cause minor infection subcutaneously. This investigation is to utilize a non-invasive dual spectrum infrared imaging system to evaluate the Port-A wound and to detect the infection. Aim: 1. To build the database of infra-red thermal images of Port-A wound healing. 2. To investigate the thermal images of skin contamination related CRBSI and to compare with the thermal images of the CRBSI of unknown foci

NCT ID: NCT02063633 Not yet recruiting - Clinical trials for To Correlate RPM Respiratory-gating Methods Analyses, Treatment Response, and Normal Tissue Metabolic Effect.

PET With Respiratory Gating Technique in Evaluation of Response and Normal Tissue Effect in Thoracic Cancer

Start date: March 2014
Phase: N/A
Study type: Observational

Technologic advances in the field of radiation oncology have made in possible to deliver a highly conformal and accurate radiation dose to a target tissue. Accompanying the rapid implementation of these novel techniques is often a reduction in the radiation margins, which reinforces the importance of accurate target delineation, and reduces the side effect of therapy. F-18 FDG PET/CT is widely used in oncology, including complete whole body staging, restaging and monitoring of tumor response in different types of cancers. As to non-oncology application, inflammation in almost any tissue will result in increased FDG accumulation. However, the normal tissue with sparing radiation may show subtle change, and would be difficult to be detected. FDG PET/CT was limited in the spatial resolution of 5 mm and low FDG-avid disease. To be evaluation of the interval change of metabolic response before and after radiotherapy of thoracic malignancies, we plan to initiate a prospective study trail the takes advantages of recent technical advances of technique in 4-dimensional PET/CT (4-D PET/CT) with respiratory gating system. Respiratory motion creates artifacts in PET and PET/CT images, and can alter diagnosis. The tumor edge would be blurred due to respiratory movement, and be underestimated the uptake value. Also, semi-quantitative measurement, standard uptake value (SUV), combined with parameters such as the lesion site and shape, which is commonly used to make the final assessment of disease would be mis-estimated. The study aims to investigate the correlation of 4-D PET/CT with respiratory gating methods and free breathing PET/CT when processing primary thoracic malignancy and normal tissue effect.
