Sex difference in prevalence of depression after stroke.

ABSTRACT:

Objective

This study investigated the sex difference in prevalence of depression at 90 days after first-ever stroke.

Methods

Patients with first-ever stroke (n = 786) were identified from the population-based Brain Attack Surveillance in Corpus Christi project (2011-2016). Poststroke depressive symptoms were assessed by the 8-item Patient Health Questionnaire, and prestroke depression status (history and medication use) was self-reported. Logistic regression was used to examine the association between sex and depression after stroke, and effect modification by prestroke depression status, accounting for missing data.

Results

Women were more likely to have a history of and be on medication for depression at the time of stroke than men (p < 0.001). Prevalence of depression at 90 days was 28.2% for men (95% confidence interval [CI], 23.7%-32.8%) and 32.7% for women (95% CI, 27.8%-37.5%). The age-adjusted odds ratio (OR) of depression after stroke comparing women and men was 1.34 (95% CI, 0.97-1.85), and fully attenuated after adjustment for sociodemographic, stroke, and prestroke characteristics. Effect modification by prestroke depression status was present (p = 0.038). Among participants on medication for depression at the time of stroke, women were significantly less likely to have depression at 90 days compared with men (OR, 0.39; 95% CI, 0.16-0.96), whereas significant sex differences were not noted among those with and without a depression history.

Conclusion

The sex difference in prevalence of depression at 90 days after first-ever stroke was not significant overall, but varied by prestroke depression status. Interventions to address and prevent poststroke depression are needed, particularly among those with prestroke depression but not undergoing treatment for depression at stroke onset.

Project description:Ischemic stroke (IS) greatly threatens human health resulting in high mortality and substantial loss of function. Recent studies have shown that the outcome of IS has sex specific, but its mechanism is still unclear. This study is aimed at identifying the sexually dimorphic to peripheral immune response in IS progression, predicting potential prognostic biomarkers that can lead to sex-specific outcome, and revealing potential treatment targets. Gene expression dataset GSE37587, including 68 peripheral whole blood samples which were collected within 24 hours from known onset of symptom and again at 24-48 hours after onset (20 women and 14 men), was downloaded from the Gene Expression Omnibus (GEO) datasets. First, using Bioconductor R package, two kinds of differentially expressed genes (DEGs) (nonsex-specific- and sex-specific-DEGs) were screened by follow-up (24-48 hours) vs. baseline (24 hours). 30 nonsex-specific DEGs (1 upregulated and 29 downregulated), 79 female-specific DEGs (25 upregulated and 54 downregulated), and none of male-specific DEGs were obtained finally. Second, bioinformatics analysis of female-specific DEGs was performed. Gene Ontology (GO) functional annotation analysis shows that DEGs were mainly enriched in translational initiation, cytosolic ribosome, and structural constituent of ribosome. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis shows that the top 6 enrichment pathways are ribosome, nuclear factor-kappa B (NF-kappa B) signaling pathway, apoptosis, mineral absorption, nonalcoholic fatty liver disease, and pertussis. Three functional modules were clustered in the protein–protein interaction (PPI) network of DEGs. The top 10 key genes of the PPI network constructed were selected, including RPS14, RPS15A, RPS24, FAU, RPL27, RPL31, RPL34, RPL35A, RSL24D1, and EEF1B2. Sex difference of ribosome in stroke-induced peripheral immunosuppression may be the potential mechanism of sex disparities in outcome after IS, and women are more likely to have stroke-induced immunosuppression. RPS14, RPS15A, RPS24, FAU, RPL27, RPL31, RPL34, RPL35A, RSL24D1, and EEF1B2 may be novel prognostic biomarkers and potential therapeutic targets for IS.
