Researchers from Istanbul University-Cerrahpasa investigated the relationship between Epstein-Barr Virus (EBV), Herpes Simplex Virus type 1 (HSV-1), and inflammatory biomarkers in individuals with schizophrenia, bipolar disorder, major depressive disorder, and healthy controls. The study, which involved 708 participants, found that EBV seropositivity was significantly higher in individuals with schizophrenia compared to healthy controls, while HSV-1 seropositivity was elevated in individuals with bipolar disorder. Furthermore, inflammatory biomarkers such as CRP, IL-6, and IL-1b were significantly increased in individuals with schizophrenia and major depressive disorder compared to healthy controls.

Key Takeaways:

  • EBV seropositivity was significantly higher in individuals with schizophrenia (90.9%) compared to healthy controls (78.9%) (OR = 3.46, 95% CI: 1.68-7.12; p = 0.001).
  • HSV-1 seropositivity was elevated in individuals with bipolar disorder (83.5%) compared to healthy controls (67.0%) (OR = 2.29, 95% CI: 1.34-3.92; p = 0.003).
  • Inflammatory biomarkers such as CRP, IL-6, and IL-1b were significantly increased in individuals with schizophrenia and major depressive disorder compared to healthy controls.
  • The study highlights the potential relevance of biomarker-based stratification for generating hypotheses regarding targeted antiviral or anti-inflammatory interventions in psychiatric populations.
  • The research was supported by the Istanbul Aydin University Scientific Research Projects Unit.
  • The study's findings suggest that EBV and HSV-1 may play a role in the development of psychiatric disorders, and that inflammatory biomarkers may serve as potential therapeutic targets.

Statistics:

  • 708 participants were included in the study.
  • 110 individuals with schizophrenia, 121 with bipolar disorder, 135 with major depressive disorder, and 342 healthy controls were assessed.
  • EBV seropositivity was higher in individuals with schizophrenia (90.9%) compared to healthy controls (78.9%) (OR = 3.46, 95% CI: 1.68-7.12; p = 0.001).
  • HSV-1 seropositivity was elevated in individuals with bipolar disorder (83.5%) compared to healthy controls (67.0%) (OR = 2.29, 95% CI: 1.34-3.92; p = 0.003).
  • Inflammatory biomarkers such as CRP, IL-6, and IL-1b were significantly increased in individuals with schizophrenia and major depressive disorder compared to healthy controls.
