Neuropsychiatric DisordersNCT07877246
A Longitudinal Natural History Study of Immune Biomarkers in Neuropsychiatric Illness
An observational study of Neuropsychiatric Disorders and Neuroinflammatory Disorders, run by National Institute of Mental Health (NIMH) at 3 sites in United States.
Trial summary
Background: Some brain or mental health conditions may be caused when a person s immune system attacks their own body. These are called immunologic neuropsychiatric disorders. In this natural history study, researchers want to see if they can find substances in the blood that can help them identify people with this… Read more about this study

About this study
Background:
Some brain or mental health conditions may be caused when a person s immune system attacks their own body. These are called immunologic neuropsychiatric disorders. In this natural history study, researchers want to see if they can find substances in the blood that can help them identify people with this kind of brain or mental illness. What they learn may help them find better ways to diagnose and treat these conditions in the future.

Objective:
To collect blood samples from people with a brain or mental illness that may be related to their immune system.
Eligibility:
People ages 1 month or older with a brain or mental illness that may be related to their immune system.
Design:
Participants will have 1 visit. This visit may be in person or by telehealth. They will answer a questionnaire about their health. They may have blood drawn for testing; this blood sample may also be taken at another medical facility and sent to the researchers.
Researchers will look at the participant s medical records and images over time. Researchers will also collect leftover blood or other tissue samples that are taken in the course of a participant s routine health care.
Participants may opt to have more visits. These visits will be every 3 to 12 months for up to 5 years. They will be asked about changes in their health since their last visit. They may opt to have blood drawn for research.

Study Description:
This study aims to identify and characterize biomarkers in biospecimens collected during clinical care or research encounters, which are not required for clinical or research testing. These "surplus" biospecimens consist of: (1) residual tissue, blood, or CSF remaining after clinical testing is complete; (2) additional blood collected for research purposes at the time of clinical biospecimen collection; (3) residual tissue, blood or CSF collected as part of a human research study; or (4) additional blood collected solely for this research protocol at the same time as biospecimen collection for a separate research protocol from which research blood are already being collected. Additionally, (5) blood will be collected longitudinally from a subset of enrolled participants. Biospecimen categories 1 - 4 do not require an additional venipuncture, whereas 5 does require an additional venipuncture. The biospecimen collection events will occur: (1) at the National Institutes of Health (NIH), (2) at medical centers and academic research institutions, and (3) at commercial phlebotomy facilities in the United States and its affiliated territories. Research activities utilizing the collected biospecimens will occur (1) at the NIH or, after de-identification, in (2) collaborating research laboratories or (3) commercial service facilities. It is anticipated that such studies will yield molecular correlates of and biomarkers for diverse neuropsychiatric illnesses.
Objectives:
The primary objective of this study is to identify immune factors that improve the diagnosis and classification of individuals with suspected immune-associated neuropsychiatric disorders.
The secondary objective is to correlate these immune factors with endotypes and endophenotypes of diverse neuropsychiatric disorders.
Endpoints:
Primary Endpoints:
- Identification of autoantibodies that are recurrently detected and statistically enriched (presence vs absence) in prespecified neuropsychiatric diagnostic or phenotypic subgroups compared with control participants, using twosided Fisher's Exact tests, with adjustment for multiple comparisons as appropriate.
- Identification of biomarker signatures that reliably classify psychotic subgroups as distinct from controls.
Secondary Endpoints:
-Derivation and characterization, when feasible, of research grade human monoclonal autoantibodies from biospecimens of participants with candidate or recurrent autoantibody responses, for use in in vitro and ex vivo mechanistic studies.

In this natural history study, researchers want to see if they can find substances in the blood that can help them identify people with this kind of brain or mental illness. What they learn may help them find better ways to diagnose and treat these conditions in the future.
Objective:
To collect blood samples from people with a brain or mental illness that may be related to their immune system.
Eligibility:

Design:
Participants will have 1 visit. This visit may be in person or by telehealth. They will answer a questionnaire about their health. They may have blood drawn for testing; this blood sample may also be taken at another medical facility and sent to the researchers.
Researchers will look at the participant s medical records and images over time. Researchers will also collect leftover blood or other tissue samples that are taken in the course of a participant s routine health care.
