Abstract

Background: We aimed to estimate the incidence of Toxoplasma infection in T. gondii-seropositive patients under allogeneic hematopoietic stem cell transplantation (HSCT). Methods: The present research was a prospective study on 54 whole blood samples of al-logeneic HSCT recipients, who were referring to bone narrow transplantation centers affili-ated to Shahid Beheshti University of Medical Sciences, Tehran, Iran in 2018. All patients were IgG positive against T. gondii. Results: Overall, 54 Toxoplasma positive pre-HCTSP patients were enrolled. 53.7% (n= 29) were male, also 1.9% (n=1) had germ-line type of the disease. The Multiple myeloma patients had higher age in comparison with other disease, but pairwise comparison showed the difference of age between Multiple myeloma patients were statistically significant with Acute lymphoblastic leukemia, Acute myeloblastic leukemia and Huntington's disease (P< 0.05). The results of PCR assay showed 5.6% (n= 3) of the patients were infected with Toxoplasma. Conclusion: PCR method has detected considerable incidence of Toxoplasma infection for monitoring HSCT recipients at risk for toxoplasmosis, and many patients who showed the incidence of toxoplasmosis had previous infections with the Toxoplasma parasite. © 2022 Yusefi et al.
