This retrospective single-center study investigates the safety, complication profile, and clinical outcomes of TPE in children with pediatric neuroimmunological disorders (PNID). Methods: Medical records of pediatric patients who underwent TPE at the Medical University of Vienna between April 2006 and October 2022 were reviewed. Inclusion criteria required TPE initiation before the age of 18 years. Data collected included diagnoses, pre-TPE therapy, TPE characteristics, complications and clinical outcomes based on retrospective documentation. Results: A total of 53 patients (60% female, median age 13 years) were included and underwent 378 TPE procedures. Most common diagnoses were pediatric-onset multiple sclerosis (23%) and autoimmune encephalitis (19%). TPE was preceded by corticosteroids and\/or intravenous immunoglobulin in 83% of patients. Complications occurred in 81% of patients and 23% of procedures and were predominantly rated mild to moderate (CTCAE I\u2013II), including nausea, hypotension, and catheter-related issues. Severe complications (CTCAE III\u2013IV) occurred in 11% of patients; no deaths were reported. Clinical improvement was documented in 84% of patients, with 42% showing significant improvement. Conclusions: TPE is a generally well-tolerated and effective treatment in PNID, with a high rate of clinical improvement and predominantly mild complications. The higher reported complication rate compared to other studies likely reflects more comprehensive documentation of minor adverse events. These findings support the use of TPE in PNID, particularly in cases refractory to first-line therapies. Standardized reporting of outcomes and complications is essential to improve comparability across studies and guide future clinical practice.<\/jats:p>","DOI":"10.3390\/children12111457","type":"journal-article","created":{"date-parts":[[2025,10,28]],"date-time":"2025-10-28T09:16:07Z","timestamp":1761642967000},"page":"1457","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Complications of Therapeutic Plasma Exchange in Pediatric Neuroimmune Disorders"],"prefix":"10.3390","volume":"12","author":[{"given":"Kathrin","family":"Eichinger","sequence":"first","affiliation":[{"name":"Division of Pediatric Pulmonology, Allergology and Endocrinology, Department of Pediatrics and Adolescent Medicine, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3825-5749","authenticated-orcid":false,"given":"Markus","family":"Breu","sequence":"additional","affiliation":[{"name":"Department of Neurology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marleen","family":"Renken","sequence":"additional","affiliation":[{"name":"Department of Neurology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8022-7736","authenticated-orcid":false,"given":"Sandy","family":"Siegert","sequence":"additional","affiliation":[{"name":"Division of Pediatric Pulmonology, Allergology and Endocrinology, Department of Pediatrics and Adolescent Medicine, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisa","family":"Hilz","sequence":"additional","affiliation":[{"name":"Division of Pediatric Pulmonology, Allergology and Endocrinology, Department of Pediatrics and Adolescent Medicine, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Glatter","sequence":"additional","affiliation":[{"name":"Division of Neonatology, Pediatric Intensive Care Medicine and Neuropediatrics, Department of Pediatrics and Adolescent Medicine, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dagmar","family":"Csaicsich","sequence":"additional","affiliation":[{"name":"Division of Pediatric Nephrology, Department of Pediatrics and Adolescent Medicine, Medical University of Viena, 1090 Wien, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4897-6953","authenticated-orcid":false,"given":"Michael","family":"Boehm","sequence":"additional","affiliation":[{"name":"Division of Pediatric Nephrology, Department of Pediatrics and Adolescent Medicine, Medical University of Viena, 1090 Wien, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2720-1019","authenticated-orcid":false,"given":"Christian","family":"Lechner","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurology, Department of Pediatrics I, Medical University of Innsbruck, 6020 Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara","family":"Kornek","sequence":"additional","affiliation":[{"name":"Department of Neurology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1455-6491","authenticated-orcid":false,"given":"Rainer","family":"Seidl","sequence":"additional","affiliation":[{"name":"Division of Pediatric Pulmonology, Allergology and Endocrinology, Department of Pediatrics and Adolescent Medicine, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,27]]},"reference":[{"key":"ref_1","unstructured":"DiFazio, M.P., Patel, N.C., Patel, M.N., Chhibber, S., and Tseng, B.S.
