Filter by:Multicenter clinical trial, phase III, controlled by active medicine, open, randomized, enroll 962 children, 2 to 12 years old, that suffer acute inflammation upper airway characterized by non-productive cough, daytime/nighttime, with duration for at least 3 and no more than 5 consecutive days (without systemic/topic use of medication during this period) followed by nasal congestion, with or without associate other nasal symptoms (sneezing, runny nose, nasal itching and/or mouth breathing). The subjects will be allocated in 2 parallel groups, and will receive the medicines of study, according of the randomization.
The purpose of the study is to investigate whether caffeinated and decaffeinated coffee consumption has acute effects on subjective appetite feelings, energy intake and biochemical markers related to appetite, inflammation and glucose metabolism compared to water consumption.
The purpose of this research study is to gain understanding of the basic responses of the lung to inflammation and specifically if a certain medication can reduce the inflammation alone or in combination with another. Inflammation is the way our bodies react to irritation or injury, and involves red, warm, and often painful swelling of the affected tissue. "Acute lung injury" involves inflammation that is not specific to one area of the lung and is caused by any one of several conditions: infection, trauma, breathing toxic substances, etc. When lung injury is severe, not enough oxygen can get into the body; this can lead to the need for mechanical support of breathing (mechanical ventilation), problems with brain, heart or other organ function, and in some cases, death.
In this project, we propose to recruit lean and obese subjects with different ethnic background (African Americans and Caucasians) to study the alterations of lipid and carbohydrate metabolism and determine whether these disturbances are linked to genetic, inflammatory, oxidative stress, and/or nutritional factors. Because systemic inflammation and insulin resistance are frequent features of obesity, we postulate that an unbalanced diet with high saturated- and low omega 3-fatty acids is linked to obesity-related inflammation and insulin resistance. We propose to investigate fatty acid metabolism and determine the links between fatty acid composition and oxidative stress in tissues of lean and obese subjects. We propose the following aims: Specific Aim 1: Evaluate nutrient intake in lean and obese subjects using the standard NHANES Food Questionnaire. Specific Aim 2: Evaluate the fatty acid composition, including omega-3, in adipose tissue depots, blood monocytes and skeletal muscle, and examine the relationship between omega-3 content and inflammatory and oxidative stress markers. Specific Aim 3: Compare the effects of omega-3 and saturated FA supplementation on inflammatory and oxidative stress markers in vitro in adipose tissue explants, preadipocytes and monocyte culture.
Adipocyte fatty acid binding protein (A-FABP) is a member of the FABP super family, is abundant in adipocytes and macrophages. Regulatory functions of A-FABP in lipid and glucose metabolism have been described, and it is suggested to play an important role in the pathogenesis of metabolic syndrome.We hypothesize that obstructive sleep apnea (OSA) may upregulate A-FABP production and thus causally contribute to metabolic dysfunction. Our group has recently demonstrated that A-FABP, expressed and secreted from adipocytes, is present in the blood stream .The levels of A-FABP correlated with various metabolic variates in the metabolic syndrome. Furthermore, we have obtained novel data in men with a range of sleep disordered breathing showed that the duration of oxygen desaturation correlated with circulating levels of A-FABP, independent of age and waist/body mass index. The current proposal aims to pursue this finding and further explore the role of A-FABP in the association of OSA and metabolic dysfunction.
Psoriasis is a chronic relapsing prevalent inflammatory disease affecting 2-4% of the world's population. Severe psoriasis is a disabling disease affecting the physical and emotional well being of patients, and its effect on quality of life is similar to that seen with other major medical diseases such as diabetes, rheumatoid arthritis, and cancer. Lately, it is increasingly being recognized that psoriasis is not merely a skin disease but is probably associated with other co-morbidities such as psoriatic arthritis, Crohn's disease, the metabolic syndrome and cardio-vascular diseases (CVD). The metabolic syndrome is a combination of diabetes mellitus type II (or insulin resistance), hypertension, central obesity, and combined hyperlipidemia (elevated LDL; decreased HDL; elevated triglycerides). As the literature linking psoriasis and the metabolic syndrome expands, also reports of an increased rate of CVD mortality in psoriasis patients accumulates. These data emphasize that metabolic dysregulations are the leading risk factors for occlusive vascular events and early death in patients with severe psoriasis. Progress in understanding the pathogenesis of these apparently diverse diseases has discovered that low-grade systemic inflammation might be the common physiological pathway that may provide the biological plausibility of the associations discovered in the epidemiological studies. Since some of these co-morbidities often become clinically apparent years after the onset of psoriasis we assume that controlling systemic inflammation might prevent or reverse some of these co-morbidities. Presently there is no study in psoriasis that shows that a "systemic" co-morbidity can be prevented or treated by reversing skin inflammation.
Background: - Allergic inflammation is central to allergy-related diseases and disorders, such as asthma, food allergies, and atopic dermatitis. Atopic dermatitis, commonly called eczema is a chronic, noncontagious skin condition, usually starting in the first years of life, which causes itching and scaling of an individual s skin. Because atopic dermatitis is a common condition in children who have allergy-related diseases, including asthma, researchers are interested in studying both individuals with atopic dermatitis and their close relatives (parents and children) to better understand how allergy-related diseases develop and progress. In addition, some patients with inherited disorders with features including atopic dermatitis or other aspects of allergy such as food allergy, asthma, hay fever, hives, and others, will also be seen. Objectives: - To study the natural history of diseases of allergic inflammation, such as atopic dermatitis or genetic disorders associated with allergic inflammation. Eligibility: - Children and adolescents between 1 month and 21 years of age who have a documented history of moderate to severe atopic dermatitis. - Individuals between 1 month and 80 years of age who have a suspected genetic or inherited allergy disorder related to atopic dermatitis or allergic pathways. - Child and adult relatives of eligible participants will also be studied on this protocol. Design: - The study will require one initial visit to the National Institutes of Health Clinical Center (lasting 1-5 days), as well as any required follow-up visits for treatment and research studies. Participants will receive treatment for atopic dermatitis and other allergic diseases as part of the study for up to 1 year. - Participants will have some or all of the following tests as part of this study: - A detailed physical examination and medical history - Allergy skin prick testing to examine participants' responses to different allergens. - Blood samples for additional allergen testing, testing the immune system, and other research purposes - Skin punch biopsy to take a skin sample - Lung function tests to measure airflow from the lungs and inflammation - Food-related tests to diagnose potential food allergies - Leukapheresis to collect white blood cells only - Research samples, including stool specimens, saliva samples, buccal swabs (to collect cells from the inside of the cheek), and skin cell samples - Clinical digital photography to provide images of affected and healthy skin. - Participants will be asked to return for follow-up visits and tests for up to 1 year after the initial visit(s).
Intraocular delivery of ketorolac will be an effective means to treat inflammation and macular edema and prevent structural complications and vision loss in patients with uveitis who are unable to tolerate corticosteroids due to their side effects.
The investigators are hoping to discover the cause of chest pain in patients with a normal coronary arteriogram. For patients with chest pain coronary angiography is the standard method by which the blood vessels of the heart can be visualized and any narrowing can be assessed. In some cases the investigators find totally normal coronary blood vessels or only minor disease. Such a finding is associated with an excellent long term prognosis. However, as a large proportion of patients with normal coronary arteries or mild coronary narrowings often continue to experience recurrent chest pains the investigators are interested in understanding the mechanisms responsible for this. The investigators hypothesise that in many cases, coronary artery spasms are responsible for the recurrent chest pains. These spasms usually respond to treatment with drugs known as vasodilators. The acetylcholine test (ACH-test) has been recommended by the European Society of Cardiology and the American College of Cardiology as a diagnostic test. This test can reveal whether the coronary blood vessels have a tendency to go into spasm. The investigators plan in this study to carry out the test in patients who have chest pains suggestive of coronary narrowings but are found to have normal or only mildly narrowed coronary arteries on angiography. A positive test -indicating a tendency for spasm- may help guiding therapy with vasodilators, which are often very effective to prevent coronary spasms. The investigators would also like to take blood samples during the test (before and after) from every patient to measure blood markers and see if there is a relation between these markers and the result of the ACH-test.
