Reducing Innate Inflammation in New Onset Type 1 Diabetes
Type 1 Diabetestype1diabetes1 moreThis study aims to determine whether Lactiplantibacillus plantarum 299v (Lp299v) supplementation will reduce systemic inflammation and prolong residual beta cell function in individuals newly diagnosed with Type 1 diabetes. The investigators hypothesize that probiotic-induced alterations in the intestinal microbiota may favorably alter the post-onset disease state.
Angiotensin II and Chronic Inflammation in Persistent Microvascular Dysfunction Following Preeclampsia...
PreeclampsiaWomen who develop preeclampsia during pregnancy are more likely to develop cardiovascular disease later in life, even if they are otherwise healthy. The reason why this occurs is unclear but may be related to blood vessel damage and increased inflammation that occurs during the preeclamptic pregnancy and persists postpartum. The purpose of this investigation is to 1) determine the mechanisms contributing to this lasting blood vessel damage and chronic inflammation, and to 2) identify factors (both physiological and pharmacological) that mitigate these negative effects in order to inform better clinical management of cardiovascular disease risk in women who have had preeclampsia.
Anti-retroviral Therapy, Medications for Opioid Use Disorder, Opioids and HIV Infection - Study...
Opioid-use DisorderHIV-1-infection6 moreHIV infection, as well as exposure to opioids (including heroin), are associated with systemic immune activation including increased microbial translocation from the gut. The overall objective of this study is to define the impact of long-term mu-opiate receptor stimulation or blockage with medication for opiate use disorder (i.e, methadone, buprenorphine/naloxone, or extended-release naltrexone) on the kinetics and extent of immune reconstitution on HIV-1 infected people who inject opiate and initiating antiretroviral therapy.

Depressive SymptomsThe purpose of this study is to determine the feasibility and preliminary efficacy of daily supplementation of freeze-dried blueberry to modulate inflammation-driven lack of motivation in 40 sedentary, older adults with depressive symptoms.
Bimodal and Coaxial High Resolution Ophtalmic Imaging
Retinitis PigmentosaMaculopathy10 moreThe knowledge of the pathogenesis of retinal affections, a major cause of blindness, has greatly benefited from recent advances in retinal imaging. However, optical aberrations of the ocular media limit the resolution that can be achieved by current techniques. The use of an adaptive optics system improves the resolution of ophthalmoscopes by several orders of magnitude, allowing the visualization of many retinal microstructures: photoreceptors, vessels, bundles of nerve fibers. Recently, the development of the coupling of the two main imaging techniques, the Adaptive Optics Ophthalmoscope with Optical Coherence Tomography, enables unparalleled three-dimensional in vivo cell-scale imaging, while remaining comfortable for the patients. The purpose of this project is to evaluate the performance of this system for imaging micrometric retinal structures.
Relationship of Exercise, Sleep, and Inflammation Markers in People Living With HIV
HivSleepThe purpose of this randomized clinical trial is to characterize the effects of two exercise interventions, high-intensity interval training (HIIT) and continuous moderate-intensity exercise (CME), on sleep and inflammation in older people living with HIV (PWH). This study is a sub-study associated with The High Intensity Exercise Study to Attenuate Limitations and Train Habits in Older Adults with HIV (HEALTH-HIV; NCT04550676). The investigators propose the following aims: Aim 1. Compare the effectiveness of HIIT and CME exercise interventions on sleep in older PWH. Aim 2. Quantify inflammation markers associated with sleep quality (self-report surveys) in older PWH at baseline, between (week 8) and after exercise interventions (HIIT and CME) (week 16). The investigators hypothesize HIIT will lead to greater improvement in sleep quality (duration and quality) compared to CME and older PWH who experience poor sleep quality and the CME intervention will have increased inflammation markers compared to older PWH who experience better sleep quality and the HIIT intervention. The intervention is being delivered by research personnel at the University of Washington associated with the HEALTH-HIV study (NCT04550676). Data for this study will only be collected at the University of Washington site of the HEALTH-HIV study.
The Effect of Donation Frequency on Donor Health in Blood Donors Donating Plasma by Plasmapheresis...
Psychological DistressProtein Deficiency1 moreThis project is a randomized controlled non-inferiority study that aims to cover knowledge gaps about the composition and development of plasma proteins, inflammation markers and mental health in Norwegian, voluntary, and unpaid blood donors who donate plasma and blood. We will include 120 male blood donors who are randomized into three groups, the first donating plasma by plasmapheresis 3 times every 2 weeks, the second donating plasma by plasmapheresis every 2 weeks and the third donating whole blood every 3 months. Blood sample analyses are done before, every 2 weeks during the donation period and after the donation period. Questionnaires regarding mental symptoms, Hopkins Symptoms Checklist 25, are done before and after the donation period. The donations extend over 16 weeks and the participants are followed up with blood tests 2 and 4 weeks after the last donation. A plasma sample from each sampling will be stored in an biobank in Innlandet Hospital Trust. The donation frequency are based on the Council of Europe's latest guidelines for plasmapheresis which allow 33 plasma donations per year with at least 96-hour intervals and previous national guidelines. The project is useful to ensure that frequent plasma donations, which are necessary to increase plasma production and the degree of self-sufficiency of plasma products in Norway, do not pose a health risk to blood donors. The primary objective is to assess the safety of blood donors donating plasma, by comparing the change in total protein and immunoglobulin G concentrations between donors who will be donating plasma 3 times every 2 weeks with donors donating plasma every 2 weeks and blood donors donating regular whole blood every 3 months. The secondary objectives are to compare the concentrations of other plasma proteins and inflammation markers and describe the development of these during plasma and blood donations between the three donations groups, compare the dropout rate and the degree of psychological distress measured by Hopkins Symptoms Checklist 25.
High-protein Oral Supplement Improves Normalized Protein Catabolic Rate and Inflammation Markers...
Renal FailureChronic Kidney Disease Requiring Chronic DialysisThe investigators propose to determine the impact of high-protein beverages on protein status and inflammation markers among CKD patients undergoing hemodialysis. A 12-week double-blind randomized cross-over trial will be used in which participants (n=22) will consume a 4-ounce high protein supplement with either whey (20 g total protein) or soy (20 g total protein). Outcomes of interest include serum urea nitrogen and inflammation markers (CRP and IL-6). The findings will contribute to the knowledge gap regarding the effect of different protein types in CKD populations which can be translated to the development of affordable supplements to prevent malnutrition in adults with non-communicable diseases.
Imaging Sex Differences in Smoking-Induced Pulmonary Inflammation
SmokingCigarette2 moreThe purpose of this research is to measure the extent of lung inflammation between different groups of participants using a radioactive tracer called [18F]NOS. A radioactive tracer is a type of imaging drug that is labeled with a radioactive tag and injected into the body.
Immuno-Genetic, Inflammation, Retro-Virus, Environment
Bipolar DisorderSchizophreniaImmunology combined to neurobiology now offer prominent tools to yield biomarkers, so far missing in psychiatry, and to design innovative treatment approaches based on the discovery of new molecular and cellular targets. As Bipolar Disorder and Schizophrenia are now known to be significantly associated with neuro-inflammation, the project I-GIVE will combine multidisciplinary approaches (clinical, viral, immunological, genetic) to explore a global hypothesis placing the Human Endogenous Retro-Virus, HERV-W, at the crossroads between susceptibility to environmental factors (such as winter-spring births, infections, urbanicity…) and genetic factors controlling immune responses. Thus I-GIVE will allow identification of new biomarkers and their correlation with clinical profiles and immuno-inflammatory/immuno-genetic markers, and description of patho-physiological mechanisms of a psychiatric disorder. In addition, I-GIVE should help to design innovative treatments and foster personalized psychiatry tailored to the needs of each patient. Notably, monoclonal antibodies anti-HERV-W Env will be assessed in a preclinical model for their ability to slow, stop, or even reverse the progression of the psychosis in patients. I-GIVE project should thus lead to major results that will have strong impacts on the scientific community, pharmaceutical industries and, in a longer term, on improvement of patients suffering Bipolar Disorder or Schizophrenia and their family.
