Clinical and lymphocyte responses to beta-carotene supplementation in 11 HIV-positive patients with chronic oral candidiasis

Abstract

Eleven HIV-positive patients with chronic oral candidiasis were supplemented with 60 to 120 mg of beta-carotene daily for 3 to 7 months. Lymphocyte profiles were evaluated at intervals to help assess immune competence. Although there was a modest increase in some lymphocyte values at 2 months, there was a significant decrease in numbers of CD4 and CD8 cells and CD4 percentage of lymphocytes after 6 months of beta-carotene supplementation. Serum triglyceride and liver enzyme levels were not affected by the beta-carotene supplementation. No improvement was observed in the control of the oral candidiasis. Under the conditions of the study, there was no indication that daily beta-carotene supplements enhanced immune competence or was of benefit in managing oral candidiasis.
