PROBLEM: Sexual violence compromises women's health and increases susceptibility to pathogens. Yet immunobiological consequences of acute sexual trauma remain incompletely understood.
METHODS: We conducted a cross-sectional study among women without HIV, comparing women exposed to forced vaginal penetration in the past 4 days (Acute Cases, n = 10), within the past 12 weeks (Cases, n = 10) and never exposed (Controls, n = 12). Sixteen immune biomarkers were measured by ELISA in plasma and cervical swabs. Blood CD4 and CD8 T cells were quantified by flow cytometry. Group differences were analyzed using Kruskal-Wallis tests followed by Dunn's test and Bonferroni correction for continuous variables and Fisher's exact test followed by pairwise Fisher's tests with Bonferroni correction for categorical variables.
RESULTS: Participants were predominantly Black (66%), publicly insured (59%) and less than 30 years of age (29%). Black women were more likely to be Acute Cases and Cases (p = 0.02). Cervical fluid from Acute Cases showed significantly elevated inflammatory cytokines, TNF-α (p = 0.02), IL-1α (p < 0.001) and IL-6 (p = 0.001); chemokines, IL-8 (p < 0.05) and MIP-3α (p < 0.001); and antimicrobials, serpinA1 (p < 0.001), SLPI (p = 0.035) and elafin (p = 0.001). Plasma biomarkers differed significantly for inflammatory cytokine IL-1α (p = 0.001), acute phase protein CRP (p = 0.03), chemokine MCP-1 (p = 0.043), antimicrobials SLPI (p = 0.001) and HBD-2 (p = 0.03) as well as MMP-1 (p = 0.004) and 9 (p = 0.006). CD4 and CD8 T cell proportions in blood were not significantly different between groups.
CONCLUSIONS: Sexual violence exposure is associated with rapid systemic and mucosal immune dysregulation that may increase susceptibility to HIV and other sexually transmitted infections.
