The findings reported in this research study represent one of the largest retrospective studies conducted to date on the association between streptococcal infections and PANDAS. Children with a previously positive streptococcus test had an 18% higher risk of any mental disorder, 51% higher risk of OCD, and 35% higher risk of tic disorders, which are diagnostic criteria for PANDAS. Study findings support the association of streptococcal and non-streptococcal infections in the diagnosis of pediatric acute-onset neuropsychiatric syndrome.

Hedman A, Breithaupt L, Hübel C, Thornton LM, Tillander A, Norring C, Birgegård A, Larsson H, Ludvigsson JF, Sävendahl L, Almqvist C, Bulik CM. Bidirectional relationship between eating disorders and autoimmune diseases. J Child Psychol Psychiatry. 2019 Jul;60(7):803-812. doi: 10.1111/jcpp.12958. Epub 2018 Sep 3. PMID: 30178543.

Conclusions: The interactions between EDs and autoimmune diseases support the previously reported associations. The bidirectional risk pattern observed in women suggests either a shared mechanism or a third mediating variable contributing to the association of these illnesses.
