Filter by:The purpose of this study is to evaluate the safety of an association with one anti-inflammatory and one gastroprotective agent compared to the one anti-inflammatory and one gastroprotective agent in patients with acute or chronic osteoarticular inflammation.
The current treatment of individuals with alpha-1 antitrypsin deficiency (AATD) who develop lung disease (COPD) is the administration of intravenous purified alpha-1 antitrypsin (augmentation therapy) at a fixed dose of 60 mg/kg per week. This dose aims at increasing the deficient AAT serum levels just above a predetermined "safety threshold" of 11 uM. However, normal levels of AAT are between 25-50 uM. AAT has shown not only to inhibit lung proteases such as neutrophil elastase, but also to modulate inflammation. Given that many subjects with AATD who receive augmentation therapy still have significant lung disease and inflammation, this study will evaluate whether doubling the dose to 120 mg/kg/week has an effect in decreasing lung inflammation. Only the dosing of 60 mg/kg /week has received FDA approval. FDA has granted an IND number to this study to test the higher dose of 120 mg/kg/week. The study will evaluate systemic (serum) and pulmonary (bronchoscopy samples)markers of inflammation in 3 phases: standard dose (4 weeks), double dose (4 weeks) and standard dose (4 weeks).
The purpose of this study to determine whether Fish oil (Omega-3 Fatty Acid) supplementation has an impact on inflammation and lean body mass in older adults. The investigators expect that Fish oil supplementation will reduce inflammation and prevent the loss of lean mass compared to placebo.
To evaluate the safety and efficacy of OTX-DP as a sustained release drug (dexamethasone) depot when placed in the canaliculus of the eyelid for the treatment of ocular inflammation and pain in subjects who have undergone cataract extraction with intra-ocular lens implantation.
Rationale: It is well established that increased intake of saturated fatty acids (SFA) is associated with incidence of cardiovascular heart disease (CHD). This effect is mediated by dietary saturated fat's impact on fasting plasma cholesterol levels. Research is needed to clarify the association between dietary fatty acids and metabolic risk markers beyond lipid profile. World Health Organisation (WHO) has recommended reduced intake of SFA with energy replacement from monounsaturated fatty acids (MUFA) or carbohydrates (CARB). However, limited evidence is available on the effects of dietary fatty acids on insulin sensitivity and secretion. The current study is designed to investigate the effects of SFA versus MUFA versus CARB on insulinemic response and lipid metabolism in healthy individuals with central obesity. Study design: A randomized, crossover, single blind design study was carried out. The subjects consumed controlled diets for 6 weeks each. They were provided 3 meals per day during weekdays in which SFA, MUFA and CARB diet was assigned to them randomly. Protein content was standardised at 14% energy. The SFA and MUFA diets each provided 31.5% energy intake from fat, with 69% of the total fats replaced by test fats (approximately 49 g/d based on a 2000 kcal basic diet). Each individual fatty acid provided approximately 7% of the total energy intake. The CARB diet provided approximately 34 g/day experimental fat based on a 2000 kcal basic diet. The CARB diet replaced 7 % energy of carbohydrate from total fat with the exchange from oleic acid (C18:1). Hypothesis: Changing energy from dietary fat (SFA and MUFA) to carbohydrate will influence insulin sensitivity, endothelial and vascular function, pro-inflammatory markers and lipid metabolism differently in individuals with metabolic syndrome. SFA (palm olein) may be comparable with MUFA (high oleic sunflower oil) with regards to its effects on insulin sensitivity, endothelial and vascular function and inflammation
The hypothesis of the study is that tomato extracted lycopene will be able to decrease postprandial oxidation and inflammation in healthy weight men and women when compared to Placebo.
Protocol Summary Constitutive STAT3 activity is implicated in many malignancies including Cutaneous T Cell Lymphoma. It is also essential for Th17 differentiation, a subset of CD4 effector T cell, implicated in chronic inflammatory conditions and possibly CTCL. HDAC inhibitors have shown activity in CTCL but their exact mechanism of action is not known. It is known that HDAC inhibitors regulate STAT3 transcriptional activity and hence can potentially be active in CTCL through modulation of the STAT3 pathway. The hypothesis is that Th17 cytokines contribute to the initiation of cancer by creating a pro-inflammatory microenvironment that predisposes cells to neoplastic transformation. To probe this, the investigators will compare the differences in cytokine production and gene expression in the skin resident T cells from patients with benign dermatoses and CTCL as well as in the blood/circulating lymphocytes of healthy donors and Sezary syndrome (SS). The investigators will also investigate whether HDAC inhibitors have a direct impact on the number of Th17 cells, the cytokine production by these cells and phosphorylated STAT3 protein in CTCL with subsequent treatment cycles. The objectives of this study are 1. Observe the epigenetic, transcriptional and phenotypic changes that take place in T cell during malignant transformation 2. Understand the mechanism of action of HDAC inhibitors in CTCL. Methods: Skin biopsy specimens from cutaneous T cell lymphoma (CTCL) patients and benign skin conditions namely eczema, dermatitis and psoriasis will be obtained through a standard punch biopsy procedure from the skin lesion. Additionally, 15 ml of peripheral blood from CTCL patients who have Sezary syndrome (SS) and from patients with benign skin condition will be collected. CTCL patients, who are starting treatment with HDAC Inhibitors namely Vorinostat and Romidepsin, will have a total of 3 skin biopsies and/or blood draws. The first procedure would be before starting treatment with either of these HDAC inhibitors. Two more skin biopsies and/or blood draws will be performed after first and second cycle of treatment. Levels of Th17 cytokines, IL-17, IL -22 and pSTAT3 protein will be determined by IHC staining in the skin and cytokine levels in the blood will be assayed by sandwich ELISA method.The investigators will also assay the mRNA levels of the transcription factors of the different T effector cells by qPCR.
Cystic Fibrosis (CF) is a fatal, recessive genetic disorder characterized by progressive inflammation and lung damage. It is unclear whether current treatment strategies, which focus on detection and eradication of pathogenic microorganisms in the lung, are the best way to prevent the initiation of early inflammation and lung damage. This study asks how early acquisition of microbial flora occurs in infants with CF and healthy baby controls, and whether this process initiates or influences early inflammation and clinical disease progression in CF.
This is a double-blind, placebo-controled, randomized trial to investigate if aspirin pre-treatment has anti-inflammatory effects in a model of acute lung injury induced by inhaled endotoxin (LPS) in healthy human volunteers.
Genetic factors contribute to risk factors for cardiovascular disease, such as blood lipids, blood pressure, obesity, diabetes, and may also influence dietary choices, physical activity, and responses to stress. The most robust genetic variant associated with myocardial infarction (MI) is the 9p21 variant, which may raise the risk of MI by up to 40% in those who carry 2 copies of the gene. The investigators recently found that among those who carry the 9p21 variant, the risk of MI may be "turned off" if individuals eat a diet high in fruits and vegetables. The investigators seek to determine how a "prudent" or "anti-inflammatory" diet interacts with the 9p21 risk allele to alter the risk of MI.
