NCT00163098
A randomised, controlled study investigating the effect of UK-369,003 on exercise tolerance in patients with COPD
NCT00238836
The University of Ottawa and Élisabeth Bruyère Research Institute are conducting a study of preventive care for frail patients at risk of functional decline. At risk patients are assigned by chance to continue receiving their standard care from their family physician or receive additional care from a nurse practitioners and a pharmacist. In collaboration with the family physician, they develop an individualized care plan, a treatment and management road plan, for each patient, which they implement over the study period of one approximately year. The objective of the study is to compare the effectiveness of the model of care that includes the nurse practitioners and pharmacist against standard care in preventing functional decline, to determine the acceptability of this model of care to patients, their caregivers and the medical team, and to evaluate the cost implication of the program.
NCT00303121
Clinic-based evaluation of patients compliance with topical medications in the treatment of glaucoma. Also assessing effectiveness of delivery techniques among these patients.
NCT00309660
Treatment with PPARgamma ligands have been shown to reduces intestinal inflammation in murine models of colitis. The aim of this study was to evaluate the effect of treatment with local PPARgamma ligand (rosiglitazone) in distal ulcerative colitis.The patients are treated with rosiglitazone enema, once a day, for fourteen days. Disease activity was assessed before and after treatment by endoscopical and clinical activity score.
NCT00374725
In this trial we test the hypothesis that a probiotic containing Lactobacillus acidophilus and Lactobacillus rhamnosus is an effective therapy for patients with ulcerative colitis.
NCT00044369
Varicose veins in the scrotum (varicocele) are responsible for \>20% of male infertility in the US. Varicocele are associated with decreased sperm number and markedly reduced sperm fertilizing ability. Surgical repair or removal of varicocele restores fertility in only 1/3 of cases. The goal of this study is to identify markers that predict the outcome of variocele correction. This would offer considerable health cost savings. Based on preliminary findings, we will obtain testis biopsies and semen specimens from infertile men with varicocele and prospectively examining the levels of cadmium, a toxic metal, and expression of genes required for normal sperm function. The semen and biopsies will be obtained during clinically dictated procedures. Cadmium and gene expression will be compared with response to varicocele repair (i.e., increased sperm production; pregnancy).
NCT00347893
Selective laser trabeculoplasty (SLT) is a new method to reduce intraocular pressure in eyes with open angle glaucoma or ocular hypertension. SLT may also be effective for cases with previously failed ALT procedures. We will study the efficacy and safety of the SLT procedure.
NCT00346541
Glaucoma, an optic neuropathy characterized by progressive visual field loss, is the leading cause of irreversible blindness worldwide. The condition has a substantial heritable basis, as illustrated by the numerous loci and genes identified to date, and the large proportion of patients having a family history. Interleukin-1 (Il-1) is an important mediator of inflammation. There are 2 pro-inflammatory cytokines, Il-1 alpha and Il-1 beta. The genes encoding Il-1 are located within a 430kb region on chromosome 2q14.2. The role of Il-1 in glaucoma is a subject of recent interest. It has been shown that Il-1, produced endogenously by glaucomatous cells, inhibits the apoptotic response to oxidative stress, and Il-1 has also been reported to increase outflow facility by stimulating the \_expression of matrix metalloproteinase enzymes, which in turn reduces extra cellular resistance. Recently, polymorphisms in Il-1 (particularly +3953T of the Il-1 β) were found to reduce the risk of primary open angle glaucoma. In this pilot study, we aim to investigate the role of Il-1 polymorphisms in both normal tension and high pressure glaucoma in our glaucoma patients. Both open and closed angle glaucoma will be studied. This is a pilot study of the role of immune system related polymorphisms and depending on the results, we may embark on a larger investigation of other immune genes in glaucoma
NCT00239512
Patent ductus arteriosus (PDA) is one of the most common complications in premature infants. Successful pharmacological closure of PDA with indomethacin was first reported in 1976. Since then indomethacin treatment has become the standard or prophylactic treatment for clinically significant PDA in premature infants. Clinically there is a high incidence of complications associated with indomethacin treatment, including hypoglycemia, necrotizing enterocolitis, GI bleeding, extension of IVH. More recently, ibuprofen has been shown to be effective for the closure of patent ductus arteriosus in premature infants without reducing mesenteric, renal, or cerebral blood flow.Ibuprofen has been shown to close the ductus in animals without reducing cerebral,intestinal or renal blood flow. Furthermore, ibuprofen enhanced cerebral blood-flow autoregulation and had some neuroprotective effect. In recent years, our strategy of PDA treatment for ELBW infants was essentially early targeted indomethacine treatment depending on echocardiographic shunt flow pattern of PDA. (Arch Dis Child 1997;77:F36-F40. Acta Paediatr Tw 1998;39:33-7. and Arch Dis Child 1999;79: F197-F200.) By this regimen, infants will be eligible for the study if their birth weight less than 1000 gm and if they had PDA without other structured cardiac anomaly confirmed by echocardiography shortly after birth (as close as possible to12 hours). After parental informed consent is obtained, infants will be randomly assigned to two groups based on a double-blined design. INDO group will receive echocardiographic assessment at interval of 12-24 hours or clinically necessary, and if the PDA had pulsatile or growing flow pattern, indomethacin is given; if the PDA had flow patterns other than growing or pulsatile pattern, no treatment is given. The subsequent dose of indomethacin is according to the echocardiographic flow patterns at interval of 24 hours from the last dose. When indomethacin was fail to close after the first course, the second course of another 3 doses of indomethacin or ibuprofen will be given. In spite of infants of INDO group or IBUO group, if PDA fail to close after 2 courses of treatment, surgical ligation of PDA would be considered according to the infant's clinical condition. Our historical data showed that the incidence of complication was about 30%. Permitting 5% chance of type I error and 20% of type II error and an absolute reduction of the incidence by 20%, 30 infants in each group is needed to detect a difference. Primary outcome of the assessment is the closure rate of PDA and the incidence of death or pulmonary hemorrhage. Secondary outcome is IVH or PVL, NEC, oliguria and CLD. We expect that, by using this treatment regimen, a high PDA closure rate can be achieved and the survival of very premature infants may be increased.
NCT00227500
This study is a randomised, placebo-controlled study of the effect of treatment with the HMG-CoA reductase inhibitor, pravastatin, in HIV-infected, protease inhibitor treated patients with high serum cholesterol. We hypothesise that pravastatin will result in greater reductions in cholesterol than placebo when used in conjunction with appropriate dietary advice.
NCT00000148
To assess the long-range outcomes of sequences of interventions involving trabeculectomy and argon laser trabeculoplasty in eyes that have failed initial medical treatment for glaucoma.
NCT00328991
This study is a double-blinded, controlled clinical intervention trial to evaluate the efficacy of duct tape occlusions therapy for the treatment of common warts. 80 patients completed this study, and were randomized 1:1 to receive pads which contained either moleskin+transparent duct tape or moleskin alone. The patients wore the pad over the target wart for 7 days at a time, removed the pad on the evening of the 7th day, and replaced the pad on the 8th day. This cycle was repeated for 8 weeks or until the wart resolved. The hypothesis was that duct tape occlusion therapy would be more therapeutic than moleskin for the treatment of the common wart. However, in our study there was only 21% resolution rate in the duct tape arm vs. 22% in the control group.
NCT00327405
The use of ocular compression and suture release have helped to improve the safety and decrease the risks of glaucoma filtering surgery. This study looks at the decrease in intraocular pressure and glaucoma medications required following glaucoma filtering surgery.
NCT00120978
Large population-based studies suggest that patients with chronic obstructive pulmonary disease (COPD) are 2 to 3 times at risk for cardiovascular mortality, which accounts for a large proportion of the total number of deaths. How COPD increases the risk of poor cardiovascular outcomes is largely unknown. However, there is growing evidence that persistent low-grade systemic inflammation is present in COPD and that this may contribute to the pathogenesis of atherosclerosis and cardiovascular disease among COPD patients. Inflammation and more specifically, C-reactive protein (CRP), has been linked with all stages of atherosclerosis, including plaque genesis, rupture and subsequent thrombo-fibrosis of vulnerable vessels. Recently, our group has demonstrated in a relatively small study that short-term inhaled corticosteroid (ICS) therapy can repress serum CRP levels in stable COPD patients. Conversely, withdrawal of ICS leads to a marked increase in serum CRP levels. Although very promising, these data cannot be considered definitive because the study was small in size and scope (N=41 patients). Additionally, this study did not address the potential effects of combination therapy with ICS and long-acting β2 agonists (LABA). This is an important short-coming because combination therapy of ICS and LABA have been shown to produce improved clinical outcomes over ICS monotherapy and is commonly used by clinicians in the treatment of moderate to severe COPD. We hypothesize that inhaled fluticasone (Flovent®) reduces systemic inflammation and that combination therapy (Advair®) is more effective than steroids alone in reducing systemic inflammation in COPD. In this proposal, we will implement a randomized controlled trial to determine whether ICS by themselves or in combination with LABAs can: 1. reduce CRP levels in stable COPD patients and 2. reduce other pro-inflammatory cytokines, which have been linked with cardiovascular morbidity and mortality such as interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1)
NCT00150943
Background: Atherosclerotic renal artery stenosis (ARAS) is associated with progressive loss of renal function and is one of the most important causes of renal failure in the elderly. Current treatment includes restoration of the renal arterial lumen by endovascular stent placement. However, this treatment only affects damage caused by ARAS due to the stenosis and ensuing post-stenotic ischemia. ARAS patients have severe general vascular disease. Atherosclerosis and hypertension can also damage the kidney parenchyma causing renal failure. Medical treatment focuses on the latter. Lipidlowering drugs (statins) could reduce renal failure progression and could reduce the overall high cardiovascular risk. The additional effect on preserving renal function of stent placement as compared to medical therapy alone is unknown. Therefore, the STAR-study aims to compare the effects of renal artery stent placement together with medication vs. medication alone on renal function in ARAS patients. Method: Patients with an ARAS of ≥50% and renal failure (creatinine (Cr) clearance \<80 mL/min/1.73 m2) are randomly assigned to stent placement with medication or to medication alone. Medication consists of statins, anti-hypertensive drugs and antiplatelet therapy. Patients are followed for 2 yrs with extended follow-up to 5 yrs. The primary outcome of this study is a reduction in Cr clearance \>20% compared to baseline. This trial will include 140 patients.
NCT00224653
To assess the potential benefits on mechanical ventilation plateau pressure of pressure controlled mode versus volume controlled mode for laparoscopic bariatric surgery in obese patients (BMI \> 35). High plateau pressures encountered in obese patients due to their reduced pulmonary compliance could be lowered using pressure controlled mechanical ventilation.
NCT00309582
Nevirapine (NVP)-based antiretroviral therapy (ART) has been commonly used in many developing countries due to its affordability and feasibility. Nonetheless, the potential drug-drug interaction between NVP and fluconazole (FLU) is a major concern. NVP can induce cytochrome P450 isoenzymes in the liver while FLU inhibit the activity of this enzyme. The recent report has demonstrated that fluconazole significantly raises plasma NVP levels and may cause serious hepatotoxicity. Conversely, NVP does not significantly influence the plasma level of FLU. However, there have not been enough data or any recommendations to adjust NVP dosage for the concurrent use of both drugs in order to avoid the adverse events. A previous study has demonstrated that genetic disposition may play a role in NVP hypersensitivity reactions. There is little data of safety and tolerability for concurrent use of NVP and FLU in Asian populations. We therefore conducted this prospective observational study to compare the trough plasma NVP levels and frequencies of adverse events among antiretroviral HIV-infected patients who did not receive FLU and received FLU in different dosages for cryptococcosis prophylaxis or treatment; and subsequently received NVP-based ART regimens.
NCT00299754
Most studies of labour induction with misoprostol used doses higher than 25mg and intervals of 3-4 hours. We studied a low-dose regime of 25mg misoprostol and compared its efficacy as single dose or double dose with dosing interval of 6 hours to our current regime of 3 mg dinoprostone pessary.
NCT00121147
The purpose of this study is to compare the additive effect on eye pressure of Azopt and Alphagan P to Travatan.
NCT00288548
We want to study the effect of the combination of metoprolol (a beta-blocker) with formoterol (a beta-agonist) on long function in patients with Chronic Obstructive Pulmonary Disease (COPD). There are more and more clues that a beta-blocker, when well chosen and in the right dosage, won't harm the long function in patients with COPD. Since a beta-blocker can be a valuable addition to treating patients with heart problems we would like to see if this category of medication can be available for COPD patients in the future.
