Toxoplasmosis gondii and dilated cardiomyopathy; serological and echocardiographic study

The present study comprised 50 patients [36 males and 14 females, 10 - 70 years old] and 15 normal subjects of matched age and sex as control group. They were clinically diagnosed as cases of advanced idiopathic dilated cardiomyopathy [DCM]. It was shown that the incidence of toxoplasmosis seropositivity was 14/50 [28%] in these patients, 5/14 [35.7%] with IgM seropositivity and 9/14 [64.3%] with IgG seropositivity. There was no relation between the toxoplasmosis serological profile [i.e. the magnitude or the type of antibody] and the studied echocardiographic parameters
