Filter by:The primary hypothesis is that INT-747 will cause a reduction in alkaline phosphatase levels in Primary Biliary Cirrhosis patients, over a 12 week treatment period, as compared to placebo.
Cystic fibrosis is a genetic disease caused by mutation of the cystic fibrosis transmembrane conductance regulator (CFTR). The purpose of the study is to investigate the effects of miglustat on CFTR function in cystic fibrosis patients.
This study will examine whether five drugs (pravastatin, Losartan, Zileuton, N-acetylcysteine and erythromycin) used together can slow the course of pulmonary fibrosis (scarring of the lung tissue) in patients with Hermansky-Pudlak Syndrome (HPS). Patients with this disease have decreased skin color (albinism), bleeding problems, and sometimes colon problems. Two of the known types of Hermansky Pudlak syndrome, type 1 and type 4, are at high risk of pulmonary fibrosis between the ages of 30 and 50. Patients 18 to 70 years of age who have Hermansky-Pudlak Syndrome with a serious loss of lung function due to pulmonary fibrosis may be eligible for this study. Participants begin taking pravastatin on study day 2 and start a new drug every 3 days. Patients who experience no problems with the medicines return home and continue on the drugs for the next 2 years. They return to the NIH Clinical Center every 3 months for a medical history, physical examination, and blood, urine and lung function tests. CT and bone density scans are done every year. The study may continue for up to 3 years.
Hepatocellular carcinoma (HCC) is the fifth commonest cancer in the world with poor prognosis, as the annual mortality is almost equivalent to the incidence. This is mainly due to late diagnosis and co-morbid liver dysfunction. HCC is prevalent in our region than in the West due to prevalent Hepatitis B infection and carriers. At the time of diagnosis, only 10 - 20% of HCC patients are candidates for liver resection or transplantation. Almost 40-50% of patients have such poor liver function and co-morbid conditions that only supportive cares are offered. Thus the median survival time is 18-24 months for resectable disease, 6 months for unresectabe disease and 3 months for metastatic disease. Current screening methods for HCC in high risk patients depend on alpha-fetoprotein (AFP) and ultrasound of the liver. Neither test is sensitive or specific enough for early detection. Therefore, early diagnosis with novel protein biomarkers is needed urgently and may provides hope to improve treatment outcome. Our preliminary study in 49 HCC patients have identified several proteins such as truncated complement C3a, albumin, B2 microglobulin, may be potentially helpful in early diagnosis. We have started a large prospective and longitudinal study in July 2006, with nearly 100 patients accrued. This application is to extend and expand our current study. We aim to (i) identify and validate novel protein biomarkers for early diagnosis of HCC (ii) conduct longitudinal proteomics with most up-to-date methods to discover new biomarker for early detection and prognostication of HCC (iii) set up gene and plasma depository and clinical database for HCC in collaboration with Singapore Tissue Network.
This was a multicenter, randomized, double-blind, placebo-controlled study of patients with severe, though stable, cystic fibrosis (CF) whose routine treatment included Pulmozyme. Patients were randomized to either continue Pulmozyme or have therapy withdrawn for 2 weeks (placebo group). Patients must have had stable CF symptoms without any change in therapy for 2 weeks prior to enrollment in order to participate.
The purpose of this trial is to evaluate the effects of a single dose of denufosol versus placebo on mucociliary clearance in patients with mild to moderate CF lung disease
Patients with cystic fibrosis (CF) need to frequently undergo courses of IV antibiotic therapy. To avoid a high number of venipunctures peripheral venous catheters (SPVC) or cannulas are used. Because of the irritant action of the drugs used, SPVC's often do not last for the whole antibiotic course (usually of two weeks) and the patient has to be punctured again for the insertion of a new IV line. With the passing of time the veins are more difficult to be found. An alternative to the use of a cannulas is the surgical insertion of a central venous catheter. This intervention may have contraindications or, specially in adolescents, cause unacceptable alterations of the body image. The aim of this study is to find a way to prolong the duration of the SPVC used by CF patients during antibiotic courses avoiding the irritation of the vein or a phlebitis. Design of the study: randomized controlled trial. The study will see a collaboration of nurses, physicians and technicians of the Tuscan CF Centre. The patients that will participate at the study will be randomly assigned to one of the two groups: one group will receive the antibiotics prescribed according to the maximal dilution suggested by the pharmaceutical company, the other will receive a much higher dilution (i.e. a higher volume of Normal Saline), but the time of administration will be the same. The assessment will regard: the level of inflammation of the vein (with a special visual scale) and the duration of the SPVC. The hypothesis that is to be proved is that diluting the antibiotic in a higher volume of Normal Saline it is possible to delay or prevent the irritation of the vein and the onset of a phlebitis. In case that the hypothesis will be confirmed by this study an easy, secure, low cost and immediately available system will be available to reduce the number of venipunctures necessary to complete a course of IV antibiotics.
This is an add-on, randomized, open label, clinical trial that evaluates the use of quadriceps electrostimulation as an additional retraining procedure in patients suffering from cystic fibrosis.
Suppression of stop mutations in the CFTR gene with parenteral gentamicin can be predicted in vitro and is associated with clinical benefit and significant modification of the CFTR-mediated chloride transport in nasal and sweat gland epithelium.
The three objectives of this trial are: 1. To demonstrate that a decline in hepatic metabolic function as measured by BreathID will correlate with changes in CTP and MELD scores in patients with cirrhosis. 2. To determine the critical value of hepatic metabolic function as measured by BreathID will predict which patients are at risk to develop complications of cirrhosis. 3. To determine the critical value of hepatic metabolic function as measured by BreathID will predict which patients are at risk for liver related mortality. The hypothesis is that the BreathID breath test will correlate to CTP and MELD scores, and that thresholds can be established that will help predict risk of complications of cirrhosis and mortality.
