There are about 21071 clinical studies being (or have been) conducted in Spain. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Evidence is lacking on the effects of different psychotropic drugs in the treatment of anorexia nervosa (AR). However, HVA levels seem to be elevated in this disease, therefore suggesting a role for drugs with a partial agonist profile on dopaminergic receptors. This is a pilot study assessing the effects of aripiprazole in teenagers with AR, compared with a placebo.
Poor prognosis dufuse large B-cell lymphoma (DLBCL) represents 50% of all DLBCL with overall cure rates ranging from 50-60% with modern dose-dense immunochemotherapy regimens such as R-CHOP14. Using an alternative strategy, as infusional and dose-adjusted R-EPOCH, the investigators have shown an 83% of complete responses (CR), with an estimated 5-year overall survival (OS) rate of 75% (García-Suárez et al. British Journal of Haematology 2007, 136:276). Despite this improvement in outcome, the search for new treatment strategies should continue. Therefore, compared with prior R-EPOCH the investigators decided to investigate whether the introduction of dexamethasone (40 mg IV on days 1-5) in place of prednisone (based upon data which demonstrated that the former was associated with enhanced Central Nervious System penetration) and the reduction of treatment intervals from 3 to 2 weeks would be feasible and might improve the outcome in this group of patients.
Vasculitis is group of diseases where inflammation of blood vessels is the common feature. Patients typically present with fever, fatigue, weakness and muscle and joint aches. These symptoms are very common among many different diseases, not just vasculitis. A clustering of other symptoms, physical examination findings, blood tests, radiology and biopsy help make the diagnosis. There are currently no criteria to help doctors make a diagnosis of vasculitis when a patient presents with these non specific symptoms and they are reliant on previous experience and disease definitions. One of the aims of this project is to develop diagnostic criteria for the primary systemic vasculitides (granulomatosis with polyangiitis (Wegener's), microscopic polyangiitis, Churg Strauss syndrome, polyarteritis nodosa, giant cell arteritis, Takayasu arteritis). We, the investigators, will do this by studying a large group of patients with vasculitis and comparing them to a large group of patients that present in a similar way, but do not have vasculitis. By comparing the 2 groups we will create a list of items to differentiate between vasculitis and 'vasculitis mimics'. We also aim to update the current classification criteria. Classification criteria are used to group patients into different types of vasculitis, once a diagnosis of vasculitis has been made, and are useful for studying patients in clinical trials with similar or identical diseases. The current classification criteria (American college of Rheumatology 1990 criteria) were developed 20 years ago, before the availability of some important diagnostic tests (e.g. antineutrophil cytoplasmic antibodies [ANCA]), and are now not consistent with some of the current disease definitions. Therefore to progress future research in vasculitis, it is important that the classification criteria are updated. We will recruit 260 patients with each of the 6 types of vasculitis and compare them with 1300 controls (patients with the 5 other types of vasculitis), in order to determine the optimal combination of symptoms, signs and investigations that classify each person into the appropriate group.
The advent of new antiretroviral drugs improved the management of HIV naive patients in terms of efficacy. However, the long term metabolic profile of this drugs has not yet been compared and associations between new antiretrovirals and cardiovascular events remains controversial. Moreover, the better tolerability and easy dosage of this new drugs might hypothetically influence adherence and QOL of HIV patients.
Acute pancreatitis is the most frequent (5-10%) and severe complication after endoscopic retrograde cholangiopancreatography (ERCP), that could require of surgical intervention and lead to death. A double- blind study designed to evaluate if the treatment with somatostatin in intravenous bolus before starting the ERCP procedure followed by a continuous infusion for 4 hours after endoscopic proof could prevent acute post-ERCP pancreatitis. Patients submitted to ERCP will be randomized in two groups of treatment, one will receive somatostatin and another placebo. The main aim of this study will be the incidence of acute post-ERCP pancreatitis and secondary objectives will be identify sub-groups of patient with high risk to develop post-ERCP pancreatitis, who could benefit of pharmacologic prophylaxis before the exploration. The study will include 510 patients submitted to an ERCP during a period of 3 years.
Following the sudden and unexpected emergence of influenza A(H1N1)pdm09 (2009 H1N1) virus, this observational study was initiated to estimate rates of morbidity and mortality and to examine predictors of severity among participants with 2009 H1N1 infection. In 2011, as surveillance indicated that 2009 H1N1 virus was co-circulating with other seasonal influenza A and B viruses worldwide, the protocol was expanded to include other influenza A subtypes and influenza B viruses. The current version of the protocol (released in August 2013) further broadens the scope of this observational study. With the recognition that novel respiratory viruses other than novel influenza A viruses, e.g., Middle East Respiratory Syndrome Coronavirus (MERS-CoV), could become prevalent and of major public health importance, the objectives of this protocol have been expanded.
Obesity is a serious medical problem because it increases the risk of cardiovascular disease (CVD), type 2 diabetes mellitus, and certain forms of cancer. The definition of obesity is based on an excess of body fat, not of BMI. However, BMI is the reference used to establish a graded classification of weight relative to height. Although BMI is widely used as a simple surrogate measure of body fat and has been shown to correlate closely with adiposity, it would be more appropriate to determine body fat percentage and to use this value for classification purposes. The present study contemplates the determination of the per cent body fat with the aim of establishing new diagnostic and therapeutic criteria according to the associated comorbidities.
The survival of esophageal cancer and stomach cancer (EGC) at 5 years is less than 30%. Pravastatin is a potent inhibitor of HMG-CoA reductase inhibitor that has shown increased survival in patients with advanced hepatocellular carcinoma. The objective is to evaluate the efficacy of treatment (increase in survival and recurrence-free period of the disease) with pravastatin in patients with advanced EGC. The investigators have designed a randomized, controlled and open. Advanced stage was considered for patients with T4 or N1 or M1 according to the TNM classification. It has been estimated sample size per treatment arm of 73 patients (146 patients in total). Randomization was done on a stratified by location (CE or CG). All patients receive hatitual treatment (surgery and / or chemotherapy and / or radiotherapy and / or palliative) for each of their clinical conditions. The experimental group will receive one tablet of 40 mg of pravastatin orally every 24 hours (breakfast) for 2 years. There will be a monthly monitoring of these patients for at least 2 years which includes an analytics. Every 2 months there will be an abdominal-pelvic CT scan to assess progression and treatment response.
Parallel, randomized and controlled clinical trial to evaluate the effect of 12 months of noninvasive mechanical ventilation versus conventional treatment in hypercapnic patients with stable COPD. Main objective: To evaluate the effect of 12 months of noninvasive ventilation on c-reactive protein concentration and daily physical activity in hypercapnic patients with stable COPD. Secondary objectives: To compare the plasmatic concentration of other inflammatory biomarkers between COPD patients with conventional treatment and wich noninvasive ventilation. To determine the response of breathlessness, health-related quality of life and lung function to noninvasive ventilation. To identify the COPD patients with a higher gasometric and clinic response to noninvasive ventilation.
The Icatibant Outcome Survey (IOS) is a prospective, observational disease registry designed to document the routine clinical outcomes over time in participants with angioedema treated with Firazyr® (icatibant) and/or Cinryze® (C1 inhibitor [human]) in countries where it is currently approved. The data collected will be used to evaluate the safety of Firazyr (icatibant) and Cinryze (C1 inhibitor [human]) in routine clinical practice and as a data source for post-marketing investigations.
