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.
