The association of Toxoplasma gondii infection with suicide attempts has been scarcely evaluated. Two hundred eighty-three psychiatric outpatients (156 patients with history of suicide attempt and 127 control patients without history of suicide attempt) were examined with enzyme-linked immunoassays for Toxoplasma immunoglobulin G (IgG) and IgM antibodies. Seroprevalences of Toxoplasma IgG and IgM in the cases and the controls were similar: 7 (4.5%) and 3 (1.9%) vs. 10 (7.9%) and 3 (2.4%) (p = 0.23 and p = 0.55), respectively. In contrast, the Toxoplasma IgG levels higher than 150 IU/ml were more frequently observed in the cases than in the controls (100% vs. 50%, respectively; p = 0.04). The seroprevalence of Toxoplasma infection increased with age and with the number of suicide attempts. Toxoplasma seropositivity was associated with reflex impairment, national trips, and snake meat consumption. Our results suggest that although seroprevalence of Toxoplasma infection is not associated with suicide attempts, a high anti-Toxoplasma antibody level is, therefore warranting further research.
Background: We performed a retrospective, observational study in 1156 adult subjects from the general population of Durango City, Mexico, Fifty five subjects with a history of abdominal hernia repair and 1101 subjects without hernia were examined with enzyme-linked immunoassays for the presence of anti-Toxoplasma IgG and IgM antibodies.
Results: The seroprevalence of anti-Toxoplasma IgG antibodies and IgG titers was significantly higher in subjects with abdominal hernia repair than those without hernia. There was a tendency for subjects with hernia repair to have a higher seroprevalence of anti-Toxoplasma IgM antibodies than subjects without hernia. The seroprevalence of anti-Toxoplasma IgG antibodies in subjects with hernia repair was significantly higher in subjects >= 50 years old than those < 50 years old. Further analysis in subjects aged >= 50 years showed that the seroprevalence of anti-Toxoplasma IgG antibodies was also significantly higher in individuals with hernia repair than those without hernia (OR = 2.72; 95% CI: 1.10-6.57). Matching by age and sex further showed that the seroprevalence of Toxoplasma infection was significantly higher in patients with hernia repair than those without hernia (OR: 4.50; 95% CI: 1.22-17.33).
Conclusions: Results indicate that infection with Toxoplasma is associated with abdominal hernia. The contributing role of infection with Toxoplasma in abdominal hernia was observed mainly in subjects aged >= 50 years old. Our results might have clinical, prevention and treatment implications and warrant for further investigation.
