BACKGROUND: Toxoplasma gondii is a protozoan parasite that belongs to the family Coccidae. We aimed to evaluate IgG avidity and the changes of anti-Toxoplasma immunoglobulins M (IgM) and G (IgG) in patients with acute leukemia and lymphoma.
METHODS: Ninety eight patients with Acute myeloid leukemia (AML), Acute Lymphoblastic Leukemia (ALL) and lymphoma, selected from patients referring to Imam Reza Hospital of Tabriz (38°04'N 46°18'E), in terms of the presence of anti-Toxoplasma IgM, IgG, IgG avidity antibodies and the major risk factors were evaluated.
RESULTS: The results of pre-chemotherapy evaluation showed that of the examined patients, only two cases, one patient with ALL and another patient with lymphoma, had a positive IgM titer. Overall, 46 cases had positive IgG titers, including 20 patients with AML, 15 patients with ALL and 11 patients with lymphoma. Three (3.06%) patients were positive for anti-T. gondii IgM and one of them was with new infection of toxoplasmosis in lymphoma patients. The post-chemotherapy IgG titer evaluation showed 46 [46.9% (95% CI 37.4-56.7)] positive IgG cases that this result was similar to the result of pre-treatment phase. One [1% (95% CI 0.2-5.6)] positive IgG avidity case was detected using ELISA method, in a patient with lymphoma whose IgM was also positive. There was no significant difference between the type of leukemia and the history of contact with cat.
CONCLUSION: Performing specialized tests to diagnose toxoplasma infection before starting treatment, in immunodeficiency patients who undergo chemotherapy, is necessary; therefore, these tests should be considered in therapeutic protocols.
