  • Identifies a subgroup of children with PANS characterized by the triad of PANS symptoms, joint complaints, and family history of autoimmunity (including psoriasis).

  • Suggests this subgroup may be at increased risk for inflammatory bowel disease and other immune-mediated disorders.

  • Recommends a low threshold for evaluation of gastrointestinal inflammation using biomarkers such as hemoglobin, CRP, fecal calprotectin, and endoscopy when indicated.

  • Reports that PANS symptoms may improve with effective treatment of inflammatory bowel disease.

  • Notes high prevalence of joint complaints and autoimmune family history, suggesting shared immune mechanisms with psoriasis and arthritis.

  • Proposes that treatments used in inflammatory bowel disease and arthritis warrant study for potential application in PANS.
