Prevalence of Toxoplasma gondii Infection in Hemodialysis Patients with Chronic Renal Failure and Risk Factors in Diyala Province, Iraq

ABSTRACT

@#Introduction: Toxoplasma gondii is a protozoan parasite which causes a zoonotic disease called toxoplasmosis. The main purpose of this study was to investigate the seropositivity rate of specific antibodies “anti-T. gondii IgG and IgM antibodies using enzyme-linked immunosorbant assay” in hemodialysis patients attending the Teaching Hospital, Baquba City, Diyala Province, Iraq and to determine the potentially preventable risk factors. Methods: Eighty five hemodialysis patients with kidney failure and 85 healthy volunteers were selected for this study. Results: The percentage of seropositivity for IgG antibodies in patients with hemodialysis was 54.1% while it was 38.2% among the healthy control subjects and the difference was significant between the two groups [Odds Ratio (OR)= 1.8586; 95% Confidence Interval (CI)= 1.0097-3.4212; P= 0.0465]. In contrast, IgM antibodies were not detected in any of the patients or the healthy subjects. Many risk factors were identified, including contact with cats (OR, 2.62; P= 0.0398); eating undercooked meat (OR, 2.6, P= 0.0439); drinking unfiltered water (OR, 2.86, P= 0.0433); and eating outside the home (OR, 5.6, P= 0.0024) as risk factors for toxoplasmosis. However, smoking was not found to be as a risk factor for toxoplasmosis (OR, 2.1, P= 0.1204). Conclusion: The results of the present study revealed a high prevalence of toxoplasma infection in hemodialysis patients and therefore, we recommend monitoring these patients for T. gondii infection to minimize the spreading of toxoplasmosis via treating the seropositive patients with the available commercial drugs.
