[Toxoplasma gondii IgG seroprevalence in HIV/AIDS patients].

OBJECTIVE Our aim was to determine the Toxoplasma gondii IgG seroprevalence in HIV/AIDS patients who applied to our outpatient clinic. METHODS Between January 2006 and June 2010, 164 HIV/AIDS patients were tested for Toxoplasma gondii IgG antibodies by using the ELISA method. RESULTS Of the total of 164 HIV/AIDS patients, 135 were male, 29 were female with a mean age of 36 years (range: 20-72 years). 85 (52%) of cases, T. gondii IgG was evaluated positive. In addition, positive T. gondii IgG was seen in 23 of 36 patients (64%) whose count of CD4+T cell was below 100. CONCLUSION Life threatening clinical conditions, mostly toxoplasma encephalitis, develop in cases who are T. gondii IgG seropositive with a count of CD4+ T cell lower than 100. The presence of T. gondii IgG should be investigated in all HIV infected patients due to the high risk of reactivation.
