“Conclusions: In PANS, which may be associated with an underlying immune dysregulation, IVIG [Octagam 5%] successfully ameliorated psychological symptoms and dysfunction, with sustained benefits for at least 8 weeks, and up to 46 weeks, following the final infusion. In addition, baseline immune and autoimmune profiles demonstrated significant elevations in a majority of subjects, which requires further evaluation, characterization, and study to clarify the potential immune dysfunction by which PANS manifests and progresses.”

In an open-labeled IVIG study in children with comorbid ASD and PANS/ PANDAS, anti-tubulin and anti-D2R (as measured by the Cunningham panel) were associated with responsiveness to IVIG treatment, suggesting that these autoantibodies could be biomarkers to select for positive IVIG treatment outcomes. Research continues to explore serum biomarkers and genetic risk factors that can provide a diagnostic tool and/or complement diagnosis in children with PANS/PANDAS.

In this cohort, 29 out of 34 of children treated with IVIG showed a reduction or disappearance of the symptomatology, while in 5 cases (15%), despite 3 IVIG courses, there was only temporary improvement of clinical symptoms, with their reappearance within 1 to 6 months. According to the results of literature and ours no definitive conclusions may be drawn from IVIG treatment for PANDAS. Limitations of the present study include the absence of casecontrols and long-term follow up. However, in our opinion, treatment with IVIG has been shown to be effective in PANDAS children with a serious-severe type and to be well tolerated. As it has been reported by Frankovic et al.  most of the PANS Research Consortium (PRC) members prefer use of IVIG in treatment of patients with this disorder in moderate to severe forms.

IVIG was safe and well tolerated. Between-group differences were smaller than anticipated, and the double-blind comparison failed to demonstrate superiority of IVIG over placebo. The observed open-label improvements indicate that future trials would benefit from larger sample sizes designed in part to aid in the identification of biomarkers predictive of a positive response to immunotherapy. Future investigations focused on the natural history of PANDAS are also warranted.

This case series demonstrates the benefits of IVIG therapy for youths with PANDAS/PANS, including those who had been symptomatic for several years prior to treatment. Although the generalizability of this retrospective report is limited, the selected cases represent the breadth of symptom presentations in PANDAS/PANS and provide additional evidence that IVIG may be useful in the management of children with moderate-severe symptoms.
