Abstract

Identification of the structural causes of depression is important for the treatment process, and toxoplasmosis may be related to psychiatric disorders. The aim of this study was to evaluate the relationship between Toxoplasma gondii (T. gondii) seropositivity and depression in children and adolescents. This case-control study included 37 children and adolescents aged 11-18 years diagnosed with depression who were followed by the Manisa Celal Bayar University Child and Adolescent Mental Health Service and 36 children and adolescents aged 11-18 years with no history of depressive episodes or psychiatric disorder treated by the Pediatric Outpatient Department. The T. gondii serology of these two groups was evaluated and compared. There were no statistically significant age or sex differences between the 37 participants with depression and the 36 healthy controls. Eight patients and two controls were seropositive for T. gondii, a statistically significant difference (p = 0.046). Seropositivity was significantly higher in patients with suicidal ideation (p = 0.005) than in those without suicidal ideation. The seropositivity of seven of the nine participants who attempted suicide was significantly higher (p < 0.001) than that of participants who did not. Thus, T. gondii infection may affect the predisposition for and severity of depression.
