This study aimed to investigate changes in the incidence, risk factors, microbiology, and clinical outcomes of PD\u2010associated peritonitis in the past decades.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a retrospective study that included children who initiated chronic PD at our institution between 2000 and 2017. The patients were divided into two groups according to the year of initiation: those who initiated PD between 2000 and 2008 and those who initiated PD between 2009 and 2017. The incidence and characteristics of peritonitis were compared between the groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 184 patients with a median age of 10.2\u2009years were included in this study. Of the patients, 92 experienced 210 episodes of peritonitis. The incidence rate of peritonitis decreased from 0.35 to 0.21 episodes\/patient year during the study period (<jats:italic>P<\/jats:italic>\u2009=\u20090.001). During the 2000\u20132008 period, the 2\u2010year peritonitis\u2010free survival rate was significantly lower for patients under 2\u2009years of age than for the other age groups (<jats:italic>P<\/jats:italic>\u2009=\u20090.004), whereas this was not observed during the 2009\u20132017 period. The multivariable Cox proportional hazard model showed that the &lt;2\u2009years age group had a significantly higher risk of developing peritonitis in the 2000\u20132008 period. However, this was not evident in the 2009\u20132017 period.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The incidence of PD\u2010associated peritonitis decreased, particularly in children under 2\u2009years of age. Thus, younger age may not be a risk factor for PD\u2010associated peritonitis.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jpc.16630","type":"journal-article","created":{"date-parts":[[2024,8,2]],"date-time":"2024-08-02T06:54:41Z","timestamp":1722581681000},"page":"531-537","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Decreased incidence of peritoneal dialysis\u2010associated peritonitis in young children"],"prefix":"10.1111","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4389-7917","authenticated-orcid":false,"given":"Peong Gang","family":"Park","sequence":"first","affiliation":[{"name":"Department of Pediatrics Seoul National University Children's Hospital  Seoul Republic of Korea"},{"name":"Department of Pediatrics Ajou University School of Medicine  Suwon Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yo Han","family":"Ahn","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Seoul National University Children's Hospital  Seoul Republic of Korea"},{"name":"Department of Pediatrics Seoul National University College of Medicine  Seoul Republic of Korea"},{"name":"Kidney Research Institute Seoul National University Medical Research Center  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hee Gyung","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Seoul National University Children's Hospital  Seoul Republic of Korea"},{"name":"Department of Pediatrics Seoul National University College of Medicine  Seoul Republic of Korea"},{"name":"Kidney Research Institute Seoul National University Medical Research Center  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Il\u2010Soo","family":"Ha","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Seoul National University Children's Hospital  Seoul Republic of Korea"},{"name":"Department of Pediatrics Seoul National University College of Medicine  Seoul Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,8]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-323-04883-5.50059-3"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.3345\/cep.2022.01431"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00467-006-0375-0"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.3339\/jkspn.2020.24.2.63"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1681\/ASN.2006101158"},{"key":"e_1_2_5_7_1","volume-title":"NAPRTCS 2011 Annual Dialysis Report","year":"2011"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/kisup.2015.8"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00467-008-1113-6"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.3349\/ymj.2013.54.4.983"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.3339\/jkspn.2010.14.2.174"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.3339\/jkspn.2012.16.2.80"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1177\/08968608221080586"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1159\/000484344"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00467-010-1510-5"},{"key":"e_1_2_5_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.kint.2016.02.015"},{"key":"e_1_2_5_17_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00467-017-3839-5"},{"key":"e_1_2_5_18_1","doi-asserted-by":"publisher","DOI":"10.3747\/pdi.2012.00126"},{"key":"e_1_2_5_19_1","first-page":"397","article-title":"Infectious complications following laparoscopic appendectomy","volume":"49","author":"Gupta R","year":"2006","journal-title":"Can.
