[Good response to azidothymidine in 3 patients with vacuolar myelopathy].

We report 3 drug abusers with human immunodeficiency virus (HIV) infection who had presented with myelopathic symptoms. A diagnosis of vacuolar myelopathy associated with HIV was made. The patients had a favorable response to azidothymidine. They were followed up as outpatients, and they showed a significant clinical improvement within 1-3 months of therapy. They remained stable 11 months afterwards. The patients with this type of disease may benefit from azidothymidine therapy.
