ABSTRACT
BACKGROUND:
Childhood brain tumors are a significant global health challenge, yet the etiology of these tumors remains elusive. While research has identified potential risk factors, recent studies have explored the involvement of infectious agents, particularly Toxoplasma gondii (T. gondii), in brain tumor development.METHODS:
This study aimed to explore the prevalence of T. gondii infection in children diagnosed with brain tumors and to investigate the potential association between T. gondii infection and childhood brain tumors in Egypt. A total of 64 children with brain tumors and 92 healthy controls were enrolled in this study. Demographics and risk factors data were collected using structured questionnaires. Serological assay using ELISA technique was performed to detect anti-T. gondii antibodies in both cases and control groups.RESULTS:
This study revealed a significantly higher seroprevalence of T. gondii infection in brain tumor cases (62.5 %) compared to healthy controls (38 %). Furthermore, a strong association was observed between T. gondii seropositivity and childhood brain tumors (odds ratio 2.7). Notably, the consumption of unwashed vegetables emerged as a significant risk factor for T. gondii infection in Egypt. Analysis of T. gondii seroprevalence across different subtypes of brain tumors revealed varying rates, with glioma cases displaying a striking 100 % seroprevalence.CONCLUSIONS:
These findings support the hypothesis that T. gondii infection may be a risk factor for childhood brain tumors and emphasize the need for further research in this area. The study also highlights the potential implications of control of T. gondii infection for prevention and treatment of childhood brain tumors.Palavras-chave
