An increasing body of evidence indicates that an immune basis might underline a number of pediatric neuropsychiatric disorders. Research studies found a subgroup of children who had Obsessive compulsive (OCD) and/or tic disorders following a Group A beta-hemolytic streptococcal (GAS) infection. The subgroup is identified by the acronym, PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections. More recently, several PANDAS variants have been described, including adult-onset variant. There are many evidences that OCD/tic symptoms could be due to an immunologic reaction against brain tissues following a streptococcal infection.
The purpose of this study is to know if sertraline (one of the SSRI approved by FDA to improve OCD/tic symptoms in these patients) plus antibiotic (benzathine penicillin G or azithromycin in case of penicillin allergy) is more effective than SSRI only.
Patients who will not respond to antibiotic will be treated with intravenous immunoglobulin (IVIG) in order to inactivate the immune reaction versus brain tissues.(No treatment response is based on the lack of a Y-BOCS score improvement of at least 35%).
- To determine the safety and efficacy of SSRI+AB compared to SSRI only.
- To test the safety and additional beneficial effects of high dose of IVIG on antibiotic prophylaxis for the treatment of OCD symptoms in non-responders patients with PANDAS.
- Participants will be screened to obtain medical history and other information at Neurologic and Psychiatric Sciences Department of Florence University Hospital and at Paris-est University.
- Participants will receive a treatment of either SSRI+AB or SSRI+placebo for 12 weeks (double-blind randomized trial)
- Patients who will not respond to AB will be admitted to the hospital to receive IVIG for 5 days, for 5 consecutive months.
- Follow-up visits will take place 3 and 6 months after the first evaluation, followed by 6 months follow-ups for 3 additional years.
Blood samples (including blood cytokine determination), ECG, Doppler and 2-dimensional echocardiogram EEG, imaging studies (2 tesla MRI), and other tests will be performed both before and after the treatment with SSRI+AB or SSRI+placebo and in case also after IVIG treatment.

|Official Title:||Antibiotic Treatment and Intravenous Immunoglobulin Double-blind, Randomized, Placebo-controlled Trial for PANDAS|
|Study Start Date :||June 2013|
|Estimated Primary Completion Date :||December 2013|
|Estimated Study Completion Date :||June 2016|
Active Comparator: SSRI+AB
Intervention: sertraline+antibiotic (penicillin/azithromycin) 12 weeks treatment with a combination of sertraline (to a maximum of 200 mg/day)and one antibiotic ( benzathine penicillin G 1.200.000 U every 3 weeks or, in case of allergy, azithromycin 500 mg/week ). Patients who will not respond to SSRI+antibiotic (penicillin/azithromycin) will be treated with IVIG (2g/kg over 5 days for 5 consecutive months)
Drug: Sertraline+Antibiotic (penicillin/azithromycin)
12 weeks treatment with a combination of Sertraline (to a maximum of 200 mg/day) and an antibiotic (benzathine penicillin G 1.200.000 U every 3 weeks or, in case of allergy, azithromycin 500 mg/week.
Non-responder patients will be treated with IVIG (2g/kg over 5 days for 5 consecutive months)
Patients who will not respond to SSRI+antibiotic (penicillin/azithromycin) will be treated with IVIG (2g/kg over 5 days for 5 consecutive months)
Placebo Comparator: SSRI+placebo
Intervention: Sertraline+placebo 12 weeks treatment with a combination of sertraline (to a maximum of 200 mg/day) and a placebo
12 weeks treatment with a combination of sertraline (to a maximum of 200 mg/day) and placebo
- The improvement of OC/tic symptoms will be superior in patients treated with SSRI+AB and in case with IVIG, compared with those treated with SSRI+placebo, as assessed by the YBOCS/YGTSS [ Time Frame: 6 months ]
- The degree of treatment response is expected to correlate with the percentage reduction in antibodies titers following IVIG administration [ Time Frame: 6 months ]
- The degree of treatment response is also expected to correlate with decreased inflammation in specific regions of the brain, as demonstrated by macroscopic changes and microstructural alterations on MRI and serum and CSF cytokines and chemokines [ Time Frame: 6 months ]
