Active clinical trials for "Inflammation"

This Strategic Research Project is a translational proof-of-concept study that will determine whether vitamin D3 has potential to prevent recurrent tuberculosis (TB), as indicated by enhanced resolution of pulmonary inflammation detected using 18F-FDG PET-CT scanning. The extent of pulmonary inflammation detectable on PET-CT scanning is a validated biomarker that has previously been shown to predict risk of TB recurrence in patients taking anti-TB treatment. The investigators propose to explore whether vitamin D3 can enhance resolution of PET-CT-detectable pulmonary inflammation, on the basis of extensive preliminary data from in vitro studies and a Phase 2b clinical trial that the investigators have conducted, showing that high-dose vitamin D3 accelerates resolution of peripheral blood inflammatory responses in patients with pulmonary TB. Forty vitamin D-deficient patients who have completed 6 months' TB treatment, but who still have residual pulmonary inflammation detectable on PET-CT scanning, will be allocated to receive either an 8-week course of high-dose oral vitamin D3 supplementation or placebo during the study period. The extent of pulmonary inflammation on PET-CT scanning will be compared between intervention vs. control groups at 8-week follow-up. If the study shows a positive result, it will generate valuable proof-of-concept data that could be used to support an application to conduct a large phase 3 trial of vitamin D supplementation to prevent TB recurrence.

The purpose of this study is to evaluate the efficacy of Saturno II association on the control of ocular inflammation post-phacoemulsification

The main objective of this research is to investigate the effect of addition of fiber on the high fat high carbohydrate (HFHC) meal induced inflammation and oxidative stress mechanisms at the molecular level in humans, in vivo. The investigators have previously shown that the intake of one HFHC meal leads to an increase in oxidative stress and inflammation. HFHC meal also induces an increase in the expression of suppressor of cytokine signaling- 3 (SOCS-3) in the mononuclear cells (MNC), which interferes with insulin signal transduction and contributes to the pathogenesis of insulin resistance. In contrast, an American heart association (AHA) meal rich in fruits and fiber does not induce these effects. These observations are important since HFHC meal not only induces oxidative stress and inflammation but also lays the foundations of a potentially greater insulin resistance through the induction of SOCS-3, TLR-4 and TLR-2.

The aim of this project is to elucidate how high-fat meals with different kinds of dairy products affect postprandial responses of lipid metabolism and inflammatory markers in healthy and obese subjects.

Pilot exploratory study on the effect of a Bifidobacterium breve extract, as VMK223, on plasma inflammatory markers, saliva hormones, gut microbiota and tolerance in females over 50years old. Participants are randomised in one of 4 arms: 0.25g/d VMK223, 0.5g/d VMK223, 0.75g/d VMK223, or placebo.

This study is a double blinded, placebo-controlled, randomized, parallel group study, designed to compare the efficacy and safety of VB-201 80mg taken orally once daily to placebo for anti-inflammation in HIV-infected subjects.

Entropion is a common condition in which the ageing eyelid becomes lax and rolls inwards, resulting in the eyelashes rubbing against the surface of the eye. This can cause discomfort, excessive watering and in severe cases inflammation of the surface of the eye which may lead to permanent scarring and impairment of vision. There are several options for surgical management of entropion. One of the quickest and simplest treatments to turn the eyelid outwards is to have three stitches ('everting sutures') placed into the eyelid. However recurrence of the entropion is common following this procedure alone. A more permanent operation ('definitive surgery') is to shorten and tighten the eyelid ('wedge excision') in addition to the everting sutures. One approach is to perform the everting sutures soon after the patient attends, as this procedure can be done in a clinic or minor operations theatre and provides immediate relief of symptoms, followed by the wedge excision at a later date, when a slot is available in the operating theatre (which has a longer waiting list). These procedures are routinely offered to patients at our hospital. Different surgeons use different types of stitches to turn the eyelid outwards e.g. polypropylene or polyglactin 910. Currently, there is no consensus as to which stitch causes less inflammation in the eyelid. The aim of this research study is to compare the inflammatory reaction between the two types of stitches. If there is a significant difference, this could provide useful information for surgeons in deciding which stitch is more appropriate for patients, especially those prone to scarring. We will assess the outcome of each type of stitch in terms of objective and clinical assessment of any scars (through questionnaires) and amount of inflammation caused (through examination of the tissue in the lab).

This study aimed to investigate whether femtosecond laser-assisted LASIK (FS-LASIK) surgery causes inflammation in the anterior chamber and to analyze its effect on endothelial cells.

Asthma is a disease characterised by chronic inflammation of the airways leading to symptoms including periods of shortness of breath, wheezing and a tight chest due to airway narrowing in affected patients. Current data show that one in 12 adults are currently receiving treatment for asthma in the United Kingdom (UK), with the UK having some of the highest rates in Europe. In the winter, 30-40% of the UK population are vitamin D deficient with some asthma patients having significantly lower vitamin D levels compared to normal patients. Vitamin D has been shown to be involved in the development of immune-related disorders including asthma. Cross-sectional research has shown that reduced vitamin D levels are associated with reduced lung function, increased airway hyper-responsiveness and reduced response to glucocorticoids, suggesting vitamin D levels may also implicate asthma treatment. To date, there have been three randomised controlled trials (RCT) assessing the effect of vitamin D supplementation in adults with symptomatic asthma. These trials have not found a significant effect of vitamin D supplementation on asthma. However, these studies relied on high doses of vitamin D with long time periods between doses. There is a requirement for RCTs in adults with daily supplementation of lower doses of vitamin D as it has been suggested that daily supplementation is more effective for inducing non-classical actions of vitamin D. However, vitamin D has been found to significantly improve airway function as measured by forced expiratory volume in one second (FEV1) in adults supplemented with 100, 000 international units (IU) vitamin D intramuscularly plus 50, 000 IU oral vitamin D weekly. Therefore, the effect of daily dosing on lung function also requires investigation. Furthermore, these trials have focussed on clinical outcomes without investigating the cellular mechanisms affording protection.

During last decades, an excessive intake of sugars has been observed in westernized countries, mainly due to the consumption of sugar-rich soft drinks. Epidemiological studies have pointed out a positive correlation between the consumption of such drinks and the risk of obesity, diabetes, and cardiovascular diseases. Therefore, there is a growing trend looking for new non-caloric alternatives (sweeteners) in order to reduce the sugar content of foodstuffs without losing their sweetness and tastefulness. However, some questions regarding sweeteners have recently arisen as their effects after long-term consumption have not been fully unravelled. They could also contribute to a higher caloric intake and to disrupt the gut microbiota. Besides seeking new alternatives for the high intake of sugar-rich drinks, there is a need for increasing the consumption of fruits and vegetables among general public. Developing new products to stretch the shelf-life of fresh fruits, preserving their nutrients, and reducing the energetic content of fruit juices should also be accomplished. In this sense, lemon juice has been proposed as an interesting ingredient in the elaboration of soft drinks due to its distinctive aroma and high nutritive value. Its combination with maqui berry juices contributes to stabilize the colour and phenolic compounds that both products contain (mainly flavanones for lemon juice and anthocyanins for maqui). The beneficial effects of these vegetal foodstuffs and their phenolic substances on glucose intolerance have been reported.The aim of BEBESANO is studying the beneficial effects of sugar-free, rich-in-phytochemicals drink consumption on postprandial hyperglycaemia, in order to provide alternatives to excessive sugar intake and counteract the postprandial response linked to sugar consumption in subjects with low levels of chronic inflammation such as overweight people. Moreover, BEBESANO will shed light on the interactions of food constituents with the main pathways involved in the lipid and glucose metabolism, oxidative stress, inflammation, and hormonal regulation in overweight population.
