Pediatric Acute-Onset Neuropsychiatric Syndrome: A Data Mining Approach to a Very Specific Constellation of Clinical Variables


Published Online: 7 Oct 2020Doi: https://doi.org/10.1089/cap.2019.0165

Abstract
Objectives: Pediatric acute onset neuropsychiatric syndrome (PANS) is a clinically heterogeneous disorder presenting with: unusually abrupt onset of obsessive compulsive disorder (OCD) or severe eating restrictions, with at least two concomitant cognitive, behavioral, or affective symptoms such as anxiety, obsessive-compulsive behavior, and irritability/depression. This study describes the clinical and laboratory variables of 39 children (13 female and 26 male) with a mean age at recruitment of 8.6 years (standard deviation 3.1).
Methods: Using a mathematical approach based on Artificial Neural Networks, the putative associations between PANS working criteria, as defined at the NIH in July 2010 (Swedo et al. 2012), were explored by the Auto Contractive Map (Auto-CM) system, a mapping method able to compute the multidimensional association of strength of each variable with all other variables in predefined dataset.
Results: The PANS symptoms were strictly linked to one another on the semantic connectivity map, shaping a central “diamond” encompassing anxiety, irritability/oppositional defiant disorder symptoms, obsessive-compulsive symptoms, behavioral regression, sensory motor abnormalities, school performance deterioration, sleep disturbances, and emotional lability/depression. The semantic connectivity map also showed the aggregation between PANS symptoms and laboratory and clinical variables. In particular, the emotional lability/depression resulted as a highly connected hub linked to autoimmune disease in pregnancy, allergic and atopic disorders, and low Natural Killer percentage. Also anxiety symptoms were shown to be strongly related with recurrent infectious disease remarking the possible role of infections as a risk factor for PANS.

Conclusion: Our data mining approach shows a very specific constellation of symptoms having strong links to laboratory and clinical variables consistent with PANS feature.

Revised Treatment Guidelines Released for Pediatric Acute Onset Neuropsychiatric Syndrome (PANS/PANDAS) -JCAP 2017

The special issue on PANS/PANDAS treatment guidelines was led by Guest Editors Jennifer Frankovich, MD, Stanford University, Susan Swedo, MD, NIH, and Tanya Murphy, MD, University of South Florida .

Treatment of PANS depends on three complementary modes of intervention:
1. Treating the symptoms with psychoactive medications, psychotherapies (particularly cognitive behavioral therapy), and supportive interventions.
2. Removing the source of the inflammation with antimicrobial interventions.
3. Treating disturbances of the immune system with immunomodulatory and/or anti-inflammatory therapies.

Clinical Management of PANS: Part I–Psychiatric and Behavioral Interventions
Part I—Psychiatric and Behavioral Interventions, Margo Thienemann, MD, Stanford University and coauthors present consensus guidelines for treating the psychiatric and behavioral symptoms of children with PANS/PANDAS. Symptom improvement is aimed at decreasing suffering, improving functioning, and making it easier for the children to adhere to therapeutic interventions.
