NEW METHODS IN THE DIAGNOSIS AND MANAGEMENT OF CEREBRAL TOXOPLASMOSIS ASSOCIATED WITH THE ACQUIRED-IMMUNE-DEFICIENCY-SYNDROME

Cerebral toxoplasmosis is a life-threatening condition associated with the acquired immune deficiency syndrome (AIDS). Current diagnostic and therapeutic methods have serious limitations. The diagnosis of cerebral toxoplasma infection in a patient with AIDS was assisted by the detection of specific IgM in a highly sensitive immunosorbent agglutination assay and by the demonstration of Toxoplasma gondii nucleic acid in a brain biopsy specimen by means of the polymerase chain reaction. Following initial failure of the patient to respond to treatment with sulphadiazine and pyrimethamine, clinical improvement was observed during treatment with clindamycin followed by dapsone. Further assessment of novel methods in the management of cerebral toxoplasmosis is required. © 1991 The British Society for the Study of Infection.
