NCT ID: NCT06400212 Recruiting - Clinical trials for Inflammatory Response

CytoHealth - A Study of the Inflammatory Response to Exercise

CytoHealth
Start date: April 8, 2024
Phase: N/A
Study type: Interventional

By measuring cytokines and chemokines in healthy volunteers of a range of ages and physical fitness, the researchers want to establish how the body's immune system responds to undergoing a single, short test of maximal effort exercise. There is limited research looking at fitness testing and the immune system, particularly in less fit individuals and women. This may not only reveal more about how people respond to the stress of very hard exercise, but it has strong relevance to patients who are undergoing major cancer operations. The researchers know that better fitness improves the patients chances of doing well after a cancer operation, and so patients undergo an exercise test to assess their fitness before a cancer operation. The researchers use this information to guide their treatment during and after their operation. What the researchers do not know is how the immune system responds to the exercise test and how this might be reflected in how they do after the operation. By undertaking this study, in healthy volunteers, the researchers will not only gain an understanding of how best to assess the immune system during exercise testing, and the logistics of doing this, but it will provide us data that the researchers can compare to cancer patients collected in separate, future study. The potential implication being that information about the immune system could be assessed during exercise testing and enhance how the researchers manage those individuals during and after an operation, potentially improving their outcomes. To provide a good representation of the general adult population, the researchers will recruit volunteers from two universities and staff at a hospital. Individuals invited to participate will have a blood test to assess their levels of cytokines and chemokines before and after they complete an exercise test. The exercise test will be delivered at one site only, which is a university laboratory.

NCT ID: NCT06312423 Recruiting - Immune System Clinical Trials

Safety and Pharmacokinetics of IMT504, an Immunomodulator and Tissue Repair Inducer

ECDA000/02
Start date: February 23, 2024
Phase: Phase 1
Study type: Interventional

Phase 1 open-label dose-escalation study to evaluate the safety and pharmacokinetics of IMT504 Phosphorothioate Oligonucleotide, an immunomodulator and tissue repair inducer, in healthy volunteers.

NCT ID: NCT06263686 Completed - Immune System Clinical Trials

Evaluation of the Effects of Routine Intake of Fresh vs- Pasteurized Yoghurt on the Immune System in Healthy Adults

YASI-03
Start date: June 1, 2016
Phase: N/A
Study type: Interventional

In this study, the purpose was to describe and compare the modulator effects on the immune system of the routine ingestion of fresh vs. pasteurized yoghurt. A unicentral, prospective, randomized, double-blind, parallel group nutritional study for 8 weeks was carried out comparing the ingestion of 125 g (three times a day) of the products in healthy adults. A complete battery of in vitro tests on the activity of immune system, processes and phenomena was performed.

NCT ID: NCT06190379 Completed - Immune System Clinical Trials

Aromatherapy for Upper Respiratory Health

Start date: December 1, 2022
Phase: N/A
Study type: Interventional

The purpose of this study is to confirm and quantify the effects of aromatherapy on respiratory health.

NCT ID: NCT06109337 Recruiting - ADHD Clinical Trials

Immunoprofilling of Peripheral Blood Mononuclear Cells in Children With Attention Deficit/Hyperactivity Disorder

Start date: December 4, 2023
Phase:
Study type: Observational

The goal of this observational study is to learn about The immune cell landscape of peripheral blood mononuclear cells in children with ADHD compared to typically developing controls. The main question it aims to answer are: 1.Testing the differences in immune cell subpopulations, protein expression and signaling pathways and cell subsets between two groups 2. Exploring the correlations between immune function in PBMC and resting-state brain functional networks in children with ADHD. Participants will be taken peripheral blood about 5 ml , cognitive assessment including Intelligence testing, Stroop color-word test and Trail making test, clinical interview and brain structural and functional MRI.

NCT ID: NCT05792137 Recruiting - Inflammation Clinical Trials

Postprandial Monocyte Study

PPMS
Start date: November 14, 2023
Phase: N/A
Study type: Interventional

The purpose of this research is to determine the role of a type of immune cell in blood, called a non-classical monocytes (NCMs), following consumption of a high-fat meal. Previous studies have found that monocytes are important for blood vessel health. In this study, two different high-fat meals will be used to study the effect of different types of dietary fat on postprandial NCMs. The investigators will characterize NCMs in both fasting conditions and following consumption of two different high-fat meals, and will evaluate whether the type of fat in a meal affects NCMs in blood.

NCT ID: NCT05648136 Recruiting - Clinical trials for Recurrent Miscarriage

Immune Profile Analysis and Biomarker Identification in Women With Repeated Implantation Failure or Unexplained Recurrent Spontaneous Miscarriage

ERIM
Start date: December 2, 2022
Phase: N/A
Study type: Interventional

Implantation is a determining step in human reproduction which requires the transition from a pro-inflammatory state to an anti-inflammatory state allowing the implantation of a competent embryo within a receptive endometrium, and then the maternal immunotolerance towards the alloantigenic fetus. Repeat implantation failures (RIFs), that refers to the fail to achieve a clinical pregnancy after the transfer of at least 3-4 good quality embryos or two blastocysts, and unexplained recurrent spontaneous miscarriage (RM) (≥2-3) could be related in some patients to immune imbalances characterized by an excessive and prolonged inflammatory response and/or a defect of anti-inflammatory regulation. In this context, several therapies have been evaluated in patients with RIFs or RMs in order to restore the immune balance, with heterogeneous results. No serum biomarker assay has been routinely approved to identify patients with immune imbalances that may explain repeated pregnancy failures and to predict the success of the subsequent IVF/ICSI cycle. The immunological analysis on peripheral blood will be based on the determination of the proportions of immune subpopulations (e.g. CD4+ et CD8+, TH1, TH2, TH17, Treg, ILC 1, ILC2, and ILC3) on the one hand and the circulating level of plasma cytokines on the other hand.

NCT ID: NCT05334888 Recruiting - Clinical trials for Cardiovascular Risk Factors

Sex-differential Host-microbiome CVD Risk - A Longitudinal Cohort Approach

XCVD
Start date: August 29, 2022
Phase:
Study type: Observational [Patient Registry]

The XCVD study investigates the influence of sex hormones on the composition of the gut microbiome and the possible emergence of cardiovascular risk factors. It will follow 200 healthy transgender individuals for two years during their hormone replacement therapy (HRT) and analyze them for the possible emergence of cardiovascular risk factors in relation to changes in the gut microbiome, metabolome, and immunome. We would also like to phenotype cardiovascular disease.

NCT ID: NCT05329337 Completed - Insulin Resistance Clinical Trials

The IRACTIV study will include a subset of volunteers from the MetACTIV study for whom a blood sample will be taken as part of the IRACTIV study.

NCT ID: NCT05221996 Completed - Resistance Training Clinical Trials

Minimal-Dose Resistance Training for Improving sIgA and Cortisol

sIgA
Start date: February 1, 2022
Phase: N/A
