Seroprevalence and associated risk factors of Toxoplasma gondii infection in psychiatric patients: a case-control study in eastern China.

Abstract:

:In recent years, the effect of Toxoplasma gondii infection on the cerebrum and neuropsychiatric patients has been increasingly highlighted. However, there is limited information about the epidemiology of T. gondii infection in psychiatric patients in Shandong province, eastern China. Therefore, through a case-control study, 445 patients hospitalized for diacrisis or treatment in Weihai, eastern China, and 445 control subjects from the general population of the same region matched by gender, age, and residence were examined with enzyme-linked immunoassays for the presence of IgG and IgM antibodies to T. gondii and associated sociodemographic and behavioural characteristics in a population of psychiatric patients. Seroprevalence of IgG antibodies to T. gondii in psychiatric patients (77/445, 17·30%) was significantly higher than in control subjects (55/445, 12·36%) (P = 0·038). Fourteen (3·15%) psychiatric patients and 10 (2·25%) control subjects had IgM antibodies to T. gondii (P = 0·408). Multivariate analysis using logic regression showed that T. gondii infection was associated with cats at home and consumption of raw/undercooked meat in psychiatric patients. Considering that most psychiatric patients usually have lower cognitive functioning and additional transmission routes related to their inappropriate behaviours that could enhance the risk of infection, psychiatric patients should be considered as a specific group of T. gondii infection.
