- Males had a higher median Modified Overt Aggression Scale (MOAS) score in the first year of clinic when compared with females and a higher median subscore for physical aggression.
- The median time from PANS symptom onset to first administration of immunotherapy, which did not include nonsteroidal anti-inflammatory drugs or short bursts of oral steroids, was 6.9 years for females and 3.7 years for males.
- Although the physical aggression measured by the MOAS was significantly higher in males, caregivers of males and females reported similar levels of caregiver burden.
- The two groups did not differ significantly in age of PANS onset, time from onset to clinic entry, other psychiatric symptom measures, or laboratory markers of inflammation.
Conclusion: Among patients with PANS, males exhibit more aggressive behavior when compared with females, which may advance the decision to treat with immunotherapy. Scores that capture a more global level of functioning show that despite there being a higher level of aggression in males, female patients with PANS have similar levels of overall impairment.
