PEDI Pediatric Autoimmune Neuropsychiatric Disorder Associated With Streptococcus Study

Официальное название

Feasibility of a Study to Determine the Incidence and Natural History of Children With Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS)

Обзор

The objective of the Pediatric Epidemiological Data and Incidence (PEDI) PANDAS study is to demonstrate the feasibility of enrollment and retention of subjects in a study to determine the incidence and natural history of children with Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS) with regard to spectrum, course and outcome. The investigators aim to demonstrate they can recruit and retain 85% of children who are eligible for this study. Eligible children are those who fit criteria for PANS and Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcus (PANDAS). Each child will be followed for one year.

Подробное описание

Specific Aim 1: To establish proof-of-concept of prospectively determining the incidence of PANDAS/PANS and the role of Group A streptococcus (GAS) in this group of disorders.

Specific Aim 1a: To prospectively identify and enroll children with PANDAS and PANS in geographically distinct populations of children in the US in order to determine the incidence and spectrum of these disorders.

Specific Aim 1b: To determine the role of GAS in new onset PANDAS/PANS.

Specific Aim 2a: To establish proof-of-concept for studying the clinical course and outcome over the first year of treatment prospectively in children identified through the EHR in a primary care population.

Specific Aim 2b: To augment the number of children identified and establish proof-of-concept for studying the clinical course and outcome over the first year of treatment. Investigators will prospectively enroll children recently diagnosed with PANDAS/PANS in our local specialty clinics (not included within our primary care population) within four months of symptom onset.

• Suspected diagnosis of PANS or PANDAS based on published criteria:

• PANS: (A) Abrupt, dramatic, overnight onset of obsessive compulsive disorder (OCD) or severely restricted food intake; (B) concurrent abrupt onset of additional severe neuropsychiatric symptoms from at least 2 of the following 7 categories:

• Anxiety
• Emotional lability and/or depression

• Developmental regression
• Deterioration in school performance
• Sensory or motor abnormalities, including heightened sensitivity to sensory stimuli, hallucinations, dysgraphia, complex motor, and/or vocal tics

AND (C) symptoms not better explained by another medical or neurologic disorder

• PANDAS

• Presence of OCD and/or tic disorder
• Pre-pubertal onset of symptoms (i.e., 3-12 years old)
• Episodic course characterized by very acute and severe onset and dramatic symptom exacerbations
• Neurologic abnormalities present during symptom exacerbations-motoric hyperactivity and adventitious movements
• Temporal relationships between group A streptococcus (GAS) infections and symptom exacerbations

Inclusion Criteria - External to Primary Care Group ONLY:

• Abrupt onset of symptoms (within 7 days) occurring in the past 4 months.
• Confirmed diagnosis of PANS or PANDAS based on published criteria (see above).

Exclusion Criteria (all participants):

• History of tics, OCD or food restriction/avoidance that contradicts a history of sudden onset or was present before the onset of this investigation
• Current symptom(s) of Pica
• Previous participation in the study
• Not suitable for study participation at the discretion of the site investigator (e.g., the child does not have verbal or cognitive ability adequate for self-report assessment)
• Patient or family is unable to complete the study questionnaires or procedures in English as the primary language
