Is parental report of upper respiratory infection at the onset of obsessive-compulsive disorder suggestive of pediatric autoimmune neuropsychiatric disorder associated with streptococcal infection?
The diagnosis of pediatric autoimmune neuropsychiatric disorder associated with streptococcal infection (PANDAS) requires a prospectively determined association between group A beta-hemolytic streptococcal (GABHS) infection and obsessive-compulsive disorder (OCD) or tic disorder. Screening for GABHS infection imposes a significant burden on both patient and clinician. To heighten the index of suspicion for PANDAS, it would be useful to know if parent-reported upper respiratory infection (URI) is associated with PANDAS symptoms or associated characteristics. Eighty-three consecutive, clinically referred patients aged 6 to 17 years with a primary diagnosis of OCD and their primary caregivers were asked about URI signs and symptoms at the time of OCD onset, PANDAS symptoms, OCD and tic symptoms, comorbidity, and putative PANDAS risk factors. Specific inquiry regarding URI symptoms proved more informative than general inquiry. In the URI present versus URI absent group, more patients experienced a sudden rather than insidious onset of symptoms. Additionally, more patients with a URI plus sudden onset exhibited a comorbid tic disorder. Until validated biomarkers permit retrospective diagnosis, a history that OCD began around the time of a URI should clue the clinician to look prospectively for PANDAS. Additional research is required to define the boundaries of PANDAS and to develop psychometrically reliable and valid diagnostic strategies.
