Clinical and demographic features of acutely hospitalised schizophrenia patients according to Toxoplasma gondii serostatus

Abstract

Background: Few data exist concerning the clinical correlates of Toxoplasma gondii infection in persons with schizophrenia. The aim of this study was to investigate the correlation between toxoplasmosis and schizophrenia regarding the quality of life, symptoms and course of hospitalisation in patients with schizophrenia. Methods: Acutely hospitalised patients (n = 67) were examined twice during their hospital stay. Schizophrenia psychopathology, quality of life, extrapyramidal symptoms and T. gondii antibody titres were assessed upon admission and at discharge. Results: Toxo-IgG (+) patients (59.7%) were older, less educated, more obese and less eager to undertake psychotherapy. Female gender and higher fertility were dominant in this group with abnormal involuntary movements more commonly observed. Lower antipsychotic drug doses and monotherapy were used more frequently for Toxo-IgG (+) patients. Lower education (OR 2.41, 95% CI 1.21-4.79) was the most important factor associated with higher likelihood of IgG seropositivity. High levels of Toxo-IgM antibodies correlated with lower quality of life (r = -0.37; p = 0.02) and more severe positive (r = 0.40; p = 0.01) and focal (r = 0.32; p = 0.04) schizophrenia symptoms. Conclusions: Toxoplasmosis is more common in older, obese women with lower education. Recent infection is linked to more severe schizophrenia symptoms. Patients with toxoplasmosis history were given less medication.

Associations between Toxoplasma gondii seropositivity and psychopathological manifestations in schizophrenic patients: A single-center study from Ecuador

“…The associations between T. gondii seropositivity and psychopathological manifestations in schizophrenic patients remain an area of interest [7,[19][20][21]. While the exact mechanisms by which T. gondii may influence the severity of schizophrenia are not yet fully elucidated, understanding these associations can provide valuable insights [3,[22][23][24][25][26][27].…”
