The study included 47 children hospitalized with pneumococcal or meningococcal meningitis between 2010 and 2020. Analyses involved leukocyte profiles, immunoglobulin levels (IgA, IgM, IgG), complement activity (C3, C4, CH50), and 11 single-nucleotide polymorphisms across 7 genes. Data on complications were collected from medical records, follow-ups, and patient surveys. Complications occurred in 59.6% of cases, with cognitive impairment, focal neurologic deficits, subdural effusion, and hearing disorders being most common. CH50 defects showed a statistical trend toward an increased risk of neurologic complications (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009=\u2009.064), and the TIRAP rs8177374 single-nucleotide polymorphism demonstrated a borderline trend toward significance (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009=\u2009.054). Bacterial meningitis may lead to long-term complications. Complement system disturbances and genetic predispositions are important prognostic factors influencing outcomes.\n                  <\/jats:p>","DOI":"10.1177\/08830738251374541","type":"journal-article","created":{"date-parts":[[2025,9,16]],"date-time":"2025-09-16T18:03:32Z","timestamp":1758045812000},"page":"539-544","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of Immune Risk Factors for Developing Complications After Bacterial Meningitis in Children"],"prefix":"10.1177","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0704-1011","authenticated-orcid":false,"given":"Anna","family":"Kadziszewska","sequence":"first","affiliation":[{"name":"Poznan University of Medical Science"},{"name":"Department of Infectious Diseases, Greatpoland Pediatric Center, Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ewelina","family":"Gowin","sequence":"additional","affiliation":[{"name":"Poznan University of Medical Science"},{"name":"Department of Infectious Diseases, Greatpoland Pediatric Center, Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,9,16]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1517\/14656560903277210"},{"key":"e_1_3_2_3_2","volume-title":"Invasive pneumococcal and meningococcal disease among children in Poland in 2021","author":"Skoczy\u0144ska A","year":"2022","unstructured":"Skoczy\u0144ska A, Go\u0142\u0119biewska A, Wr\u00f3bel-Pawelczyk I, et al.
