In these patients, autoimmune\/inflammatory diseases and psychiatric disorders were common in first-degree family members (71% and 78%, respectively). Most acute-onset patients had a relapsing\/remitting course (84%), prominent sleep disturbances (84%), urinary issues (58%), sensory amplification (66%), gastrointestinal symptoms (42%), and generalized pain (68%). Inflammatory back pain (21%) and other arthritis conditions (28%) were also common. Suicidal and homicidal thoughts and gestures were common (44% and 17%, respectively) as were violent outbursts (61%). Group A streptococcus (GAS) was the most commonly identified infection at onset (21%) and during flares (74%). Rates of the abovementioned characteristics did not differ between the acute-onset group and the subacute\/insidious-onset groups. Low levels of immunoglobulins were more common in the subacute\/insidious-onset group (75%) compared with the acute-onset group (22%), but this was not statistically significant (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      =0.06).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>In our PANS clinic, 40% of patients had acute onset of symptoms.

Because of the wide variety of medical and psychiatric symptoms, youth with PANS may require a multidisciplinary team for adequate care management.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/cap.2014.0081","type":"journal-article","created":{"date-parts":[[2015,2,19]],"date-time":"2015-02-19T15:43:53Z","timestamp":1424360633000},"page":"38-47","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":130,"title":["Multidisciplinary Clinic Dedicated to Treating Youth with Pediatric Acute-Onset Neuropsychiatric Syndrome: Presenting Characteristics of the First 47 Consecutive Patients"],"prefix":"10.1177","volume":"25","author":[{"given":"Jennifer","family":"Frankovich","sequence":"first","affiliation":[{"name":"Stanford University School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margo","family":"Thienemann","sequence":"additional","affiliation":[{"name":"Stanford University School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"Pearlstein","sequence":"additional","affiliation":[{"name":"Stanford University School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amber","family":"Crable","sequence":"additional","affiliation":[{"name":"Stanford University School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kayla","family":"Brown","sequence":"additional","affiliation":[{"name":"Stanford University School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiki","family":"Chang","sequence":"additional","affiliation":[{"name":"Stanford University School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2015,2,1]]},"reference":[{"key":"e_1_3_1_2_1","doi-asserted-by":"publisher","DOI":"10.1089\/cap.2010.0034"},{"key":"e_1_3_1_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/npp.2012.56"},{"key":"e_1_3_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.pediatrneurol.2004.02.011"},{"key":"e_1_3_1_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmii.2013.03.015"},{"key":"e_1_3_1_6_1","doi-asserted-by":"publisher","DOI":"10.1089\/cap.2014.0084"},{"key":"e_1_3_1_7_1","doi-asserted-by":"publisher","DOI":"10.1177\/0883073812451327"},{"key":"e_1_3_1_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10096-014-2098-7"},{"key":"e_1_3_1_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0006-3223(99)00020-7"},{"key":"e_1_3_1_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaut.2013.05.005"},{"key":"e_1_3_1_11_1","doi-asserted-by":"publisher","DOI":"10.1017\/S1092852912000491"},{"key":"e_1_3_1_12_1","doi-asserted-by":"publisher","DOI":"10.1177\/000992280404300709"},{"key":"e_1_3_1_13_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.0887-03.2004"},{"key":"e_1_3_1_14_1","doi-asserted-by":"publisher","DOI":"10.1084\/jem.144.4.1094"},{"key":"e_1_3_1_15_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.101.1.86"},{"key":"e_1_3_1_16_1","doi-asserted-by":"publisher","DOI":"10.1038\/nm892"},{"key":"e_1_3_1_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jneuroim.2006.06.017"},{"key":"e_1_3_1_18_1","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.178.11.7412"},{"key":"e_1_3_1_19_1","article-title":"Editorial commentary: \u201cWhat does immunology have to do with brain development and neuropsychiatric disorders?\u201d","author":"Leckman JF","year":"2014","unstructured":"Leckman JF, , Vaccarino FM: Editorial commentary: \u201cWhat does immunology have to do with brain development and neuropsychiatric disorders?\u201d.
