BACKGROUND: Immunocompromised patients may be at risk for reactivating the toxoplasmosis infection; therefore, early diagnosis would be highly desirable in these individuals. This study evaluated the possible association between coronavirus disease 2019 (COVID-19) and latent Toxoplasma gondii infection in Guilan province, Iran.
MATERIALS AND METHODS: The study was performed among 210 COVID-19 patients referred to Guilan University of Medical Sciences hospitals in 2022. Peripheral blood samples were taken for serum separation, collected into tubes, and kept at - 20 °C until use. Blood samples were obtained from COVID-19 patients. IgG antibody to Toxoplasma gondii was detected by a commercial ELISA kit. Accordingly, IgG absorbance levels <9 were considered harmful, 9-11 was considered borderline, and >11 was positive.
RESULTS: Toxoplasma IgG antibodies were found in 73.9 % of patients with COVID-19 in male patients. The seroprevalence of Toxoplasma in dead and lived COVID-19 male patients was 83.3 % and 66.7 %, respectively, and this difference was significant. A present study found a significant correlation between the rising titer of Toxoplasma IgG and the severity of COVID-19. There was no significant difference between the hospitalization duration factor and the seropositivity rate.
CONCLUSION: Regarding the significant association between the rising titer of Toxoplasma IgG and the severity of COVID-19. The findings demonstrated an association between the severity and mortality rate of COVID-19 with higher titer Anti-Toxoplasma IgG antibodies. Toxoplasmosis is currently considered a risk factor for COVID-19.
