Gestational age (GA) and birth weight are major factors associated with the development and progression of ROP, but postnatal systemic inflammation is also an important well-known risk factor. Methods: This study retrospectively analyzed the relationship between systemic inflammation and ROP severity using the corrected GA (CGA), which reflects the intrinsic immaturity of the infant, rather than days of life. Three acute phase reactants (APRs) were analyzed using discriminant probability and compared with conventional ROP prediction models: C-reactive protein, \u03b11AG, and haptoglobin. Results: Alpha 1AG was the best predictor of ROP onset and progression, and could be predicted with blood samples up to 30 weeks (30 W) CGA (p = 0.006). Incorporation of APR into the conventional GA + body weight (BW), ROP score, and Children\u2019s Hospital of Philadelphia (CHOP) predictive models improved the decision to treat (4\u20135% increase in discrimination probability) and helped determine whether treatment of ROP was necessary by CGA 30 W. Conclusions: Therefore, simply adding \u03b11AG protein to the assessment is useful for predicting the need to treat ROP.<\/jats:p>","DOI":"10.3390\/diagnostics15050571","type":"journal-article","created":{"date-parts":[[2025,2,27]],"date-time":"2025-02-27T05:13:58Z","timestamp":1740633238000},"page":"571","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Role of Acute Phase Reactants, Including \u03b11-Acid Glycoprotein, in Predicting Onset and Severity of Retinopathy of Prematurity"],"prefix":"10.3390","volume":"15","author":[{"given":"Yoko","family":"Nakazawa","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Nagoya City University West Medical Center, Nagoya 462-8505, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9913-1905","authenticated-orcid":false,"given":"Tsutomu","family":"Yasukawa","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Science, Nagoya City University Graduate School of Medical Sciences, Nagoya 467-8601, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haruo","family":"Goto","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Nagoya City University West Medical Center, Nagoya 462-8505, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoru","family":"Kobayashi","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Nagoya City University West Medical Center, Nagoya 462-8505, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyoko","family":"Yokoi","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Nagoya City University West Medical Center, Nagoya 462-8505, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1445","DOI":"10.1016\/S0140-6736(13)60178-6","article-title":"Retinopathy of prematurity","volume":"382","author":"Smith","year":"2013","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1001\/jamaophthalmol.2019.4502","article-title":"Individual risk prediction for sight-threatening retinopathy of prematurity using birth characteristics","volume":"138","author":"Pivodic","year":"2013","journal-title":"JAMA Ophthalmol."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"618","DOI":"10.1016\/j.survophthal.2018.04.002","article-title":"Retinopathy of prematurity: A review of risk factors and their clinical significance","volume":"63","author":"Kim","year":"2018","journal-title":"Surv.
