IgG anti-toxoplasma antibodies among asymptomatic HIV-infected patients in Marrakesh-Morocco

Detection and monitoring of anti-Toxoplasma gondii antibodies are of a great interest among human immunodeficiency virus (HIV)-infected patients, since cerebral toxoplasmosis is a life-threatening opportunistic infection within this vulnerable population. The IgG anti-T. gondii seroprevalence was assessed in 95 asymptomatic HIV-infected adults living in Marrakesh city and its surrounding areas. Our results showed a seroprevalence of 62.1%, which is high compared to most other countries. The mean of CD4+ T-cells count of involved patients was 381.9 cells/μl. Given these results, HIV-infected patients in Marrakesh region could be at high risk to develop toxoplasmosis disease, especially when CD4+ T-cells count falls below 100 cells/μl. Accordingly, there is a serious need of widening antiretroviral therapy and chemoprophylaxis against toxoplasmosis, when indicated, to ovoid toxoplasmosis reactivation among this population.
