Active clinical trials for "Inflammation"

This study collects data on microbiological, genetic and environmental factors, as well as lung function parameters (e.g. spirometry, body plethysmography, lung-MRI) to assess the complex interaction of predisposing risk factors for impaired lung development and respiratory diseases.

This study is designed to assess how KPI-121 1% compares to prednisolone acetate in reducing inflammation after cataract surgery in young children. Approximately half the participants will receive KPI-121 1% eye drops and the other half will receive prednisolone acetate.

Study Aims Understanding the gut microbiome profile in very low birth weight infants with or without ROP. The onset and aggravation of ROP and their relationship with gut microbiome will be examined. Understanding the serum inflammatory cytokine profile in these infants and its relationship with the onset and progression of ROP. Their changes and association with the other systemic disorders such as NEC or RDS or sepsis will be explored. Examiningthe associations amongmicrobiome profile and serum inflammatory cytokines and their relationship with ROP clinical features (prematurity without ROP, ROP without treatment, and ROP with treatment) in the study participant

Trauma and major operation are associated with an excessive inflammation reaction due to tissue injury. This overwhelming immune response is considered to be a major risk factor in the pathogenesis of late inflammatory complications such as acute respiratory distress syndrome (ARDS), multiple organ dysfunction syndrome (MODS) and sepsis. The investigators hypothesize that administration of C1-esterase inhibitor (C1-INH) will attenuate the humane inflammatory response and, thereby, reduce the risk of inflammatory complications due to surgical interventions in trauma patients with a femur or pelvic fracture

The primary objective of this study is to histologically evaluate the incorporation of AlloMend® Acellular Dermal Matrix into surrounding native soft tissue. Adults 18 years of age or greater who have undergone a pre-pectoral placement of tissue expanders for breast reconstruction and will have a histological evaluation of the AlloMend® Acellular Dermal Matrix and native tissue at time of permanent breast implantation.

Co-morbidities, including low bone mineral density, increased visceral adiposity and chronic kidney disease (CKD) are frequent in people living with HIV, and may be driven by ongoing inflammation and immune activation. Initiation of ART reduces inflammation and immune activation and is associated with changes in bone and renal biomarkers and gut microbiota. Investigators hypothesise that changes in gut microbiome when starting antiretroviral therapy correlate to changes in bone and renal biomarkers and wish to explore possible mechanisms linking these by investigating changes in markers of inflammation and immune activation.

The proposed study is designed to test the hypothesis that in human obesity, the balance of pro- and anti-inflammatory T cells in fat tissue is in fact related to macrophage phenotype and insulin resistance, and how it is related. This study is needed to confirm whether conclusions based on studies of visceral adipose tissue in mice are indeed applicable to humans. We also want to determine the relationship between insulin resistance/hyperinsulinemia and ability to lose weight in obese individuals.

This study will investigate inflammatory diseases and disorders. Inflammation is the body s immune response to many things, including infections and other acute or chronic irritants. It may also be a sign of abnormal immune function. This study will allow evaluation and long-term follow-up of such disorders to: Establish and maintain a group of patients that may be eligible for other NIAID protocols. Provide clinical training and experience for NIAID fellows. Provide a mechanism for NIAID staff to maintain their clinical skills. Serve as a starting point for new investigations of syndromes not currently under study. Patients between 1 and 80 years of age with acute or chronic inflammation, including but not limited to viral, fungal or bacterial infections, or abnormal immune responses may be eligible for this study. Immediate family members of patients may also be enrolled for preliminary examination to see if they are affected in any way that may warrant further investigation. All patients and family members will have a history, physical examination and laboratory tests. Depending on the results, family members may require additional tests. Patients will have additional diagnostic tests indicated for their specific disease, according to accepted medical standards. These may include routine blood and urine tests, X-rays or other imaging studies, body fluid or tissue cultures, skin tests for allergic or immune responses, and others as needed. Treatments will include only medications approved by the Food and Drug Administration according to accepted dose schedules and delivery methods. Patients may be requested to donate extra blood for research studies. No more than 450 cc (30 tablespoons) will be drawn from adults within a 6-week period, and no more that 7 cc (1/2 tablespoon) from children under 18 years of age in the same time period.

The primary study objectives are: to evaluate (1) the change in ocular discomfort at 30 days and (2) the change in signs and symptoms of ocular surface disease in demodex-positive subjects beginning the use of Avenova.

Myocardial infarction (heart attack) is usually the consequence of rupture of a fatty 'plaque' in a heart artery. The presence of this fat and debris causes the propagation of a blood clot and blockage of the artery. The heart muscle normally supplied by the artery becomes deprived of oxygen and, if starved for long enough, this area of muscle dies. Much of the heart muscle damage is caused by overactivation of inflammatory cells. Whilst inflammation can be beneficial in healing processes, there is accumulating evidence that overactivation of inflammatory processes contributes to further muscle damage and cell death during myocardial infarction. We have recently developed a means of labelling human blood cells with 'nanoparticles' of iron oxide which can then safely be reinjected into the blood to allow the cells to be tracked and seen in the body using a conventional magnetic resonance scanner. In the proposed study we aim to recruit patients with recent heart attacks to perform similar cell labelling and reinjection of labelled cells into the same volunteer's blood stream via the arm to track the fate of the blood cells over the course of days to months. We think that the labelled inflammatory cells will 'home' to the site of the heart attack and will be visible using magnetic resonance imaging (MRI) of the heart. We aim not only to highlight the role of inflammatory cells in myocardial infarction, but also propose that, if successful, this technique could be used in the future to assess the effects of antiinflammatory treatments currently being developed for the treatment of patients with heart attacks. The technique could also be extended to allow labelling of other cell types, including stem cells, to let us further understand how these cells may contribute to repair of damaged organs including the heart.
