Elucidating Age-related Comorbidity Patterns in Down Syndrome (DS)
France, Spain, United Kingdom230 participantsStarted 2021-06-10
Plain-language summary
This study is a non-drug, multicenter, prospective cohort study. It will be conducted in 300 volunteers from 12 to 45 years of age (inclusive) with a diagnosis of Down syndrome from 3 countries (France, Spain, United Kingdom (UK)). The basic hypotheses of the study are the following:
1. Diseases (and comorbidity) arise from one or more biological networks perturbed by the genetic disorder (trisomy 21) through interaction with environmental risks factors and epigenetic changes.
2. Health comorbidity patterns in DS individuals (particularly of obesity and related conditions) will likely vary by age and sex.
3. Obesity comorbidity patterns will relate to variation in factors including lifestyle, stress-response, severity of intellectual disability (ID) and variation in cognitive domains such as executive functioning.
4. Stress responses, as measured with cortisol concentrations, will differentiate individuals with DS who are obese and those who are not. Extremes in phenotype (Obese vs. Non-obese) will be related to differences in the metabolomic, transcriptomic, and microbiome concentrations.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Males and females aged 12 to 45 years
* With established genetic diagnosis of Down syndrome (full trisomy 21; based on karyotype results - not exclusion if not available but will need to confirm karyotype if not done previously)
* Availability of parent/caregiver to accompany the subject to clinical visits and to be willing to give written informed consent, when necessary
Exclusion Criteria:
* Confirmed mosaic trisomy 21, partial trisomy 21, or translocation
* Comorbid conditions - Participation is allowed as long as the condition(s) are considered stable and it do not interfere with the participation of the study
* Subjects with evidence of dementia or meeting clinical diagnoses for dementia
* Participation in a medication treatment trial in the last 3 months prior to the study
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Since this Down Syndrome study has already completed recruitment and was focused on observing patterns like BMI, diet, and physical activity rather than testing a treatment, what practical findings from research like this might actually be relevant to my or my loved one's current care plan?
2This trial measured mental health alongside physical health factors like diet and exercise in people with Down Syndrome — does my doctor think there are any gaps in how we're currently monitoring these areas together, and should we be doing more comprehensive check-ins?
3Since this was an observational study tracking lifestyle and health patterns rather than testing a new therapy, are there any active treatment trials for Down Syndrome-related comorbidities that my doctor thinks would be worth exploring next?
4The trial looked at leisure-time physical activity using a specific questionnaire — given that exercise habits can affect so many health outcomes in Down Syndrome, is my current level of physical activity something my care team feels we should be paying closer attention to?
5Because this study focused on age-related comorbidities in Down Syndrome, should I be asking about any age-specific health screenings or preventive steps that my doctor recommends we prioritize right now?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
