Few studies have examined inflammation shortly after trauma as a predictor of later PTSD symptoms.

Plasma cytokines were assessed from a study blood draw in the ED: an inflammatory index (standardized sum of generally pro-inflammatory markers interleukin [IL]-6, IL-8, tumor necrosis factor alpha [TNF-\u03b1], interferon gamma [IFN-\u03b3]), and generally anti-inflammatory IL-10. PTSD symptoms were self-reported at 2\u00a0weeks, 8\u00a0weeks, 3\u00a0months, and 6\u00a0months post-ED. Covariate-adjusted repeated-measures regressions estimated associations between inflammation and PTSD symptoms, overall and sex-stratified.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0033291726103833_sec3\" sec-type=\"results\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 742 participants (age\n                      <jats:italic>m<\/jats:italic>\n                      \u00a0=\u00a040.0 [13.7]; 479 [64.6%] female), PTSD symptoms were elevated then modestly decreased over follow-up.
