[Toxoplasma serology in HIV infected patients and suspected cerebral toxoplasmosis at the Central Hospital of Bobo-Dioulasso (Burkina Faso)].

A study was conducted in the Internal Medicine unit of Bobo-Dioulasso Hospital. Of the 1828 HIV positive patients admitted in medical wards, 268 presented neurological symptoms. 25.4% had positive Toxoplasma gondii serology. Encephalitis was associated with 12.5% of this latter group and intracranial hypertension with focal neurological defects affected a further 47.5% of them. Presumptive treatment of toxoplasmosis led to significant clinical improvement in 60% of cases. Toxoplasma gondii serology should be part of the standard check-up for every HIV-infected patient, and toxoplasmosis chemoprophylaxis should be given to those with positive toxoplasma serology. Presumptive therapy of toxoplasmosis should be started for all HIV positive patients with focal neurological manifestations in the absence of a cerebral scanner.
