NCT00000966

Brief Summary

To evaluate the effectiveness and toxicity of oral azithromycin and pyrimethamine as acute therapy for toxoplasmic encephalitis in AIDS patients. To assess the toxicity and effectiveness of azithromycin alone as maintenance therapy. Encephalitis caused by Toxoplasma gondii is the most frequent cause of focal central nervous system infection in patients with AIDS. Untreated, the encephalitis is fatal. Standard treatment for toxoplasmic encephalitis is associated with serious adverse effects. Thus, alternative treatments are needed.
