In a recent large study of the relationship between C-reactive protein (CRP) and posttraumatic stress pathology, researchers demonstrated an association between systemic inflammation and stress pathology (PTSD; trending with depression), which remained after adjusting for potentially confounding variables. These results contribute to research findings suggesting a salient relationship between inflammation and posttraumatic stress pathology. Researchers analyzed a large naturalistic cohort sharing a discrete physical and mental health trauma from the destruction of the World Trade Center (WTC) towers on September 11, 2001 (n=641). They found:
- CRP was positively associated with PTSD severity, trending toward association with depression, but not with anxiety.
- CRP was positively associated with re-experiencing and avoidance symptom clusters, and trended toward associations with negative cognitions/mood and arousal.
