Active clinical trials for "Inflammation"

Rationale: COPD is increasing in prevalence among people living with HIV/AIDS (PLWHA) as widespread use of ART has increased longevity in this population. In rural Ugandan ART clinics, we report COPD prevalence of 6.22%. Currently, it's not fully known what drives chronic lung inflammation in PLWHA population despite being virologically suppressed on ART. There is need to explore factors driving chronic airway inflammation among PLWHA. Airway microbiome has been implicated in the pathogenesis of COPD. Preliminary analysis from our study revealed that, specific microbes were significantly enriched in PLWHA with COPD with more lung bacteria impacted by HIV than COPD. These findings suggest that HIV-associated changes in unique airway microbial genera may be driving COPD among PLWHA in our cohort. Currently, we don't know how such genera drive chronic airway inflammation. Study objectives: In this study, we will: (1) establish a relationship between airway microbiome and Th17/Treg cellular phenotypes among HIV-infected individuals with COPD; (2) investigate bacterial-mediated Th17 upregulation of pro-inflammatory and pro-fibrotic genes among HIV individuals with COPD and (3) explore the role of bacterial outer membrane vesicles (OMVs) in mediating microbiome driven Th17 immune responses among HIV individuals. Methods: We will conduct a 2-year case-controlled study, leveraging on the established lung microbiome cohort in rural Nakaseke district of Uganda. We will recruit 80 HIV-infected individuals ≥35 years attending the ART clinic at Nakaseke General Hospital screened for COPD as well as 80 HIV-negative controls ≥35 years attending the pulmonary clinic at Nakaseke General Hospital screened for COPD. In both cases and controls, we will consider 40 stable COPD participants and 40 participants with no COPD. Recruited participants will undergo sputum induction protocol at our newly established negative pressure sputum induction facility at Nakaseke General Hospital following established standard operating procedures. Using induced sputum samples, we will (i) perform 16S sequencing and metagenomics analysis to determine airway bacterial communities, (ii) RNA sequencing and analysis to determine gene expression profiles, mass flow cytometry and analysis to profile immune cells in induced sputum of study participants as well as (iv) ELISA tests to compare OMV levels between participants.

The present study aimed to investigate the effects of low-level laser therapy (LLLT) as an adjunct to non-surgical periodontal treatment (NSPT) on the plasminogen-activating system in Stage 3-4, Grade C periodontitis patients.

Rationale: Tinnitus is the perception of sound without an external source. In the past decade, inflammation has been implicated in the pathophysiology of tinnitus. In animal models of tinnitus, the expression of proinflammatory cytokines Tumor Necrosis Factor-α (TNF-α) and interleukine-1β (IL-1β) was increased throughout the whole auditory tract. Only two studies evaluated cytokine concentrations in tinnitus patients. In these studies an increase of IL-6 and decrease of IL-10 have been objectified. However, studies did not include tinnitus patients based on the degree of hearing loss, despite that inflammation has also been implicated in hearing loss. On the other hand, studies about inflammation in hearing loss did not (always) exclude tinnitus. Thus, it remains unclear whether the upregulated cytokine concentrations the studies are specific for tinnitus, and whether potential effects remained unsignificant because the presence of hearing loss is a confounder. Therefore, the aim of this study is to evaluate the presence of inflammation in tinnitus patients with normal hearing. Objective: The main objective is to evaluate the presence of inflammation in blood samples of human subjects with tinnitus and normal hearing, compared to healthy controls. The secondary objective is to evaluate the relation between tinnitus severity and inflammatory marker concentrations. Study design: This is a cross-sectional study. Study population: Patients who have been referred to the tinnitus consultation at the outpatient clinic will be asked to participate in this study. For the control group, healthy volunteers will be recruited. Main study parameters/endpoints: The main study parameter is the disparity in blood cytokine levels between participants with and without tinnitus. Secondary study parameters are the relation between tinnitus severity and blood cytokine concentration, and the difference in complete blood count measures in participants with and without tinnitus.

Primary Objective: To evaluate the effect of dupilumab, compared to placebo, on airway inflammation in participants with persistent asthma. Secondary Objective: To assess the safety, tolerability, and immunogenicity of dupilumab compared to placebo.

Vascular inflammation, a central feature of atherosclerosis, participates in the initiation, perpetuation and instability of plaques. Multiple clinical trials of cholesterol lowering therapy with statins have demonstrated that reductions in atherosclerotic cardiovascular disease (CVD) events are associated with reductions in both LDL cholesterol (LDL-C) and the systemic inflammatory mediator C-reactive protein (CRP). The Cardiovascular Inflammation Reduction Trial (CIRT) investigates if an anti-inflammatory agent commonly used in rheumatoid arthritis (low dose methotrexate (LDM)) can reduce CV morbidity and mortality among patients with a prior myocardial infarction or angiographically demonstrated multivessel coronary artery disease (GCO#13-1467). In this ancillary CIRT imaging study, the investigators propose to use this well validated approach by non-invasive serial FDG-PET/CT imaging in a subset of patients enrolled in the main CIRT trial to directly visualize vascular inflammation. Once the subjects are enrolled in the main CIRT trial, baseline imaging will be done and follow up imaging will be done approximately 8 months after the baseline imaging. 18FDG-PET imaging data will be acquired, analyzed centrally and results incorporated into the main CIRT database. The investigators hypothesize that LDM treatment will result in a significant decrease in plaque inflammation as measured by 18-FDG-PET/CT after 8 months as compared to placebo.

The primary objective of this clinical trial is to determine if treatment with an anti-inflammatory drug (delayed-release prednisone) improves the health-related quality of life (HRQOL) of veterans with Gulf War Illness (GWI). The primary outcome measure is a change from baseline of HRQOL with respect to physical functioning and symptoms. Secondary outcomes measures include changes from baseline levels of GWI-associated biomarkers of inflammation in peripheral blood, GWI-associated symptoms (chronic pain, fatigue, and cognitive impairment), and HRQOL with respect to mental functioning.

The purpose of this study is to compare the oral inflammatory reduction effect caused from orthodontic treatment of anthocyanin and placebo mouthrinse.

The aim of this study is to evaluate the effect of adding Vildagliptin versus Glimepiride to Metformin on markers of inflammation, thrombosis, and atherosclerosis in diabetic patients with symptomatic Coronary artery diseases. The pre-specified established biological markers of inflammation, thrombosis, and atherosclerosis will include: Interleukin 1 beta (IL-1 beta)), hs-CRP, Atherogenic index and coronary risk index, Lipid profile. and adiponectin levels..

The Vibringe is the first endodontic sonic irrigation system that enables delivery and activation of the irrigation solution in the root canal, in only one step. The activation of the disinfectant by acoustic streaming, enriches and completes the irrigation procedure and improves the success rate of endodontic treatments. It has been shown that this system significantly improves debridement. It also improves the disruption of the smear layer and biofilm by activating irrigation solutions. As there are no previous studies comparing the Vibringe system with other irrigation techniques under clinical settings, in this regard, the aim of this study is to evaluate whether irrigation with Vibringe provides more or less benefit in terms of postoperative pain when compared with the conventional needle technique.

The effects of a nutraceutical combination (NC) containing low-dose monacolin K and berberine on lipid profile, proprotein convertase subtilisin/kexin type 9 (PCSK9), subclinical inflammation and arterial stiffness were investigated in human immunodeficiency virus (HIV)-infected patients receiving stable antiretroviral therapy (ART).
